MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
1. Executive Summary Statement
Minneapolis Community and Technical College is planning to renovate the heating,
ventilating, and air conditioning systems in the Old Harmon Building, which is part of the
Management Education Center (MEC). Old Harmon consists of an underground level
and four stories above grade. In 2011, the third floor of Old Harmon HVAC was
renovated, with the introduction of a new, more efficient heating, ventilating and air
conditioning system, sized for future extension to the fourth floor. The new system uses
variable air volume distribution and hot water booster heating coils for zone temperature
control. An old constant-volume packaged HVAC rooftop unit provides heating, cooling,
and ventilation for Old Harmon (but no longer the third floor). When the other floors of
Old Harmon are renovated, the old rooftop unit will be removed. Two old, inefficient
steam boilers in the Health Science Building portion of MEC originally served the entire
MEC block of buildings. However, they presently only provide steam heat for Old Harmon
and a few other spaces. The rest of MEC is now heated with hot water furnished by a
newer, more efficient boiler plant. When the HVAC is built out for the other floors of Old
Harmon, heating for the remaining spaces with steam heat will be converted from steam to
hot water. The old steam boilers, no longer needed, will be decommissioned and removed
from the premises. Two small existing rooftop units will be converted from steam to hot
water heating. Adjacent to Old Harmon, and within MEC, is the structure known as New
Harmon, or Area E. To address maintenance needs and a potentially overloaded roof
structure, New Harmon will receive a new roof. The entire roof on New Harmon should
be replaced as part of the mechanical renovation project in order to eliminate obsolete roof
penetrations, minimize the possibility of a catastrophic failure, and to install a long term
durable roof system that will meet the MnSCU forty year life expectancy. The roof work is
combined with the HVAC work because of the removal of the old rooftop unit and because
of new roof openings which will be needed for the HVASC renovation. The HVAC work
and the roof work are interwoven. A summary of the work of the project is as follows:
•
•
•
•
•
Expand the new third floor HVAC system to also serve the fourth floor of Old
Harmon.
Build another, similar HVAC system to serve the first and second floors of Old
Harmon, replacing the old system.
Remove the old HVAC rooftop unit which presently serves Old Harmon.
Replace the roof of New Harmon.
Remove the steam boilers from the health Science Building.
The interior square footage in Old Harmon which will be affected totals about 21,300 gross
square feet.
With funding approved in June 2016, design will take place in the months that follow, and
construction is likely to take place in 2017. As shown in the table in Section 5, the
probable construction cost, in present day dollars, is $1,821,000. Adding a 10%
contingency, along with other project costs (design and project management and
Page 5 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
hazardous materials abatement), and then adding an inflation factor, the total project cost
in 2016 dollars is expected to be $2,852,200.
The backlog of deferred maintenance for Old Harmon is $4,439,000, and the FCI is 0.37.
The backlog of deferred maintenance for New Harmon is $2,964,000, and the FCI is 0.18.
Academic, operational, and workforce or economic development programs will not be
affected by this project, except that they will need to be temporarily relocated during
construction.
Section 5 of this report presents a summary of the capital cost required. Section 6
addresses ongoing costs. Section 7 includes a proposed project schedule.
The main purpose for the project is to address current deficiencies and to transform Old
Harmon into a more energy-efficient and sustainable building. This is in keeping with the
College’s Master Plan and strategic goals. The project supports MCTC’s vision and
mission by providing a comfortable, energy efficient space for teaching and learning.

2. Project Background Narrative
a.) The Existing Systems
Minneapolis Community and Technical College (MCTC) is planning to renovate portions of
the Management Education Center (MEC). This mostly academic building, located at
1314 Harmon Place (at S 13th St) in Minneapolis, houses the Continuing Education and
the Business Department. It is adjacent to the Health Science Center. Within the MEC,
in the northeast section, is a structure known as Old Harmon. It consists of an
underground level and four stories above grade. Each floor is about 7,100 gross square
feet. Refer to Appendix C for drawings of the MEC building, with the Old Harmon area
highlighted. Adjacent to Old Harmon, and within MEC, is the structure known as New
Harmon, or Area E.
Constructed in 1912, Old Harmon is mainly office space. An old packaged HVAC rooftop
unit provides cooling and ventilation for Old Harmon, but no longer the third floor. This
rooftop unit is mounted on the roof of New Harmon and is ducted across to Old Harmon. It
is in poor condition due to its age, and the replacement cost was previously quoted at
about $92,000. The old air handling unit delivers air to the first, second, and fourth floors
through old VAV boxes with pneumatic controls. All of the heat for these floors is
provided by steam radiators, using an old-fashioned one-pipe system. There is only one
steam control valve for the entire Old Harmon building. Two steam boilers in the Health
Science Building originally served all of the MEC building. However, they presently only
provide steam heat for Old Harmon and another classroom. The boilers are more than 40
years old. The rest of MEC is now heated with hot water furnished by a newer boiler plant.
The old steam boilers are much less efficient.
In 2011, the third floor of Old Harmon was renovated, with the introduction of a new
heating, ventilating and air conditioning system, at a cost of about $860,000. This
included a full gut-and-rebuild of the floor. The new HVAC system consists of a central
HVAC air handling unit, located in a room on the third floor, previously used as a vault.
Heating water and chilled water is generated at the Campus central plant, and this is
connected to the air handling unit on the third floor of Old Harmon. The College’s intent
has been to phase out the original heating and ventilation system which is inefficient,
difficult to control, and in poor condition.
According to reports, in 2010 the third floor of Old Harmon was tested for asbestos and
none was found. Some lead paint was found in walls and ceilings in Old Harmon.
Presently, there is some lead based paint at the windows. It is possible that the
renovation might disrupt materials which still have lead paint, but it is not clear at this
point. The project budget includes $30,000 for hazardous materials abatement.
The MEC block of buildings has two electric utility meters. One serves Old Harmon and
the Health Science Center. The other serves New Harmon, and the rest of the MEC
Page 7 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
block. There is a natural gas utility meter in the boiler room in the Health Science Center,
which only meters equipment serving Old Harmon.
Management Education Center (MEC) Building
According to the 2011 MCTC Master Plan, roof replacements, including New Harmon roof,
is among the top HEAPR requests. During the initial predesign process, it was
discovered that two built-up roofs of MEC are currently in place and the roof structure
could potentially be overloaded. Overloading of a roof deck and its support structure is
very serious and should be considered a life safety issue. In addition, roof core samples
showed no adhesion or attachment of the second roof system to the original built-up roof
system. It is, in effect, floating above the original roof. This lack of attachment could
result in catastrophic failure of the over-roof, with it either being partially or completely torn
off in a windstorm. Immediate attention to this particular roof area is strongly
Page 8 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
recommended. Because of the seriousness of the matters discussed above, this area
was moved up from its original rotation in the 0 – 5 reroofing budget.

3. Project Description
a.) Purpose and Rationale
This section describes the new work which will address the current deficiencies. The
proposed renovation is needed in order to transform Old Harmon into a more sustainable
building, in the following ways:
1.) By addressing deferred maintenance
2.) By providing a more comfortable working and learning environment for building
occupants
3.) By improving energy efficiency
4.) By addressing life safety concerns, by replacing the New Harmon roof
b.) Project Scope
The following paragraphs summarize the scope of the MEC renovation project, including
HVAC systems construction, equipment demolition, and roof work.
1 - The Continued HVAC Build-Out of Old Harmon
In addition to a new indoor air handling unit, the recent third-floor HVAC replacement
included new air ducts and air distribution through variable volume controllers (VAV boxes)
and duct-mounted hot water booster heating coils for zone temperature control. The air
handling unit was sized to also serve the fourth floor, through an extension of the supply
and return air ductwork. As part of the continuing renovation, the fourth floor will be builtout in a similar way. Also, another, similar indoor air handling unit will be installed, along
with VAV boxes and coils, to serve the first and second floors of Old Harmon. The
additional air handling unit will be located in a space directly below the third floor fan room.
Heating water and chilled water pipes were stubbed into the room. The new air handling
unit will include a supply fan, a return-relief fan, heating coils, cooling coils, filters, and
automatic dampers. The fans will be powered through adjustable speed motor drives for
variable air volume control of fan speed according to demand. Outdoor air will be
extended from the roof to the new air handling unit for fresh air ventilation, and a means of
allowing excess air to exit the building will be provided. Chilled water piping will be
extended to cooling/dehumidification coils in the new air handling unit. Heating water
piping will be extended to coils in the air handling unit and to booster heating coils in
supply air ductwork. Electric power will be extended to the new fan motors.
Generally, each room will be a temperature zone, with a room temperature sensor and a
dedicated VAV box with a booster heating coil. Some smaller rooms with similar
occupancies will share zone terminals. The HVAC equipment will be monitored and
controlled by the MCTC Campus building automation system (BAS). New electronic
Page 12 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
automatic controls will be installed for this purpose. The BAS is based on Invensys
Niagara (presently Schneider Electric/TAC). It is estimated that there will be about 80 to
100 additional points of monitoring and control by the BAS. This will include monitoring of
motor status and space temperatures. It will include control of dampers, VAV boxes and
coil valves. The BAS will facilitate energy conservation measures, including air-side
economizer control, variable volume air supply, demand ventilation (using space CO2
sensors), and automatic supply air temperature and pressure re-set. Old heaters in two
Old Harmon building entries will be replaced with new hot water cabinet unit heaters with
automatic control.
The HVAC retrofit will
also include replacing
the present steam heat
with hot water heat in a
classroom and in the
loading dock.
At this time, there are no
plans to change the
building program. It is
intended that walls will
not change, and the
present activities will
remain the same after
the renovation takes
place. There will be
some additional, general
construction activities
associated with the HVAC renovation. It is possible that some of the existing ductwork in
the first, second, and fourth floors could be re-used, but this would need to be cleaned,
and there would be much work involved in fitting this to new VAV boxes and heating coils.
In any case, ceilings will be temporarily removed and then restored, in order to install new
equipment and materials. Additional shaft space will be created for ductwork. Some fire
sprinkler piping and heads might need to be modified or relocated to a small extent.
Along with ceilings, light fixtures will need to be removed temporarily and reinstalled. A
sanitary drain and vent will be needed in the new fan room on the second floor.
During the Predesign, other HVAC options have been given some consideration, such as
heat pumps and variable flow refrigerant systems. However these have been dismissed
in favor of the central AHU/VAV/booster heating coil system described herein. The
proposed HVAC system is considered to be the most energy –efficient option and the
most practical for the space. It would be impractical to install an HVAC system for Old
Harmon, other than the one which has been started with the remodeling of the third floor,
which included the installation of a central air handling which was sized and selected to
also serve the fourth floor. Refer to the section on Sustainability in Section IV of this
Predesign report for information about alternative energy systems.
Page 13 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
Some general construction is anticipated, in order to support the HVAC renovation. The
proposed new second floor fan room for a new air handling unit will be fitted with an
acoustic door. The walls of this might also need some acoustic treatment. Depending on
the location of the new air handling unit, some reinforcement of the structural floor system
might be needed. Openings will need to be cut and holes drilled for new air ducts and
pipes to this room. Some lay-in ceilings will need to be dismantled and reconstructed, in
order to install ducts and pipes above ceilings. In some rooms, drywall soffits might be
needed to conceal air ducts. Some small vertical pipe chases will need to be constructed.
2 - Removal of the Old Rooftop Unit
When the proposed HVAC renovation of Old Harmon is completed, the rooftop unit will not
be needed. At that point, it will be removed. It is located on the roof of New Harmon,
and its removal has implications for reroofing of that building (Refer to the next item).
3 - MEC-New Harmon Roof Replacement
The entire roof on New Harmon should be replaced as part of the mechanical renovation
project in order to eliminate obsolete roof penetrations, minimize the possibility of a
catastrophic failure, and to install a long term durable roof system that will meet the
MnSCU forty year life expectancy.
The existing concrete deck has little to no structural slope, and therefore, a fully-tapered
insulation system will be required. The existing gravel stop style roof edge will be raised
Page 14 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
to accommodate the necessary base flashings heights required to meet current MnSCU
standards.
Select masonry wall surfaces will be covered with plywood, underlayment, and sheet
metal wall panels. The walls appear to be solid wall construction and do not appear to
have through-wall flashing; therefore on these roof areas, the existing reglet will be
removed or cut off and raised to accommodate the 12" minimum base flashing height as
required to meet current MnSCU standards. This work will require the services of a
masonry consultant. The walls appear to be cavity wall construction. Therefore on
these roof areas, new double through-wall flashing will be required to provide a weathertight condition and accommodate the 12" minimum base flashing height as required to
meet current MnSCU standards. This work will require the services of a masonry
consultant. Various holes and assorted defects in adjoining or intersecting masonry walls
will be repaired in conjunction with this project. This work will require the services of a
masonry consultant. There are several windows and/or other penetrations through the
masonry wall that may need to be raised to accommodate the necessary base flashing
height. This work will require the services of mechanical, masonry, and window
consultants.
The existing drains and
leaders will be replaced
with a larger size, or
additional drains
added, to meet current
code requirements.
Also, overflow drains
and/or scuppers will be
provided.
The existing
mechanical curbs will
be raised to
accommodate the
necessary base
flashing height. All
associated
mechanical/electrical/g
as modifications will be
incorporated. Mechanical equipment will be relocated as necessary to provide a
symmetrical and unobstructed drainage layout. The existing electrical lines located on the
surface of the roof will be removed and relocated to the interior of the building. The
existing lights will be removed and relocated to an exterior wall surface and the conduit will
be relocated to the interior of the building. This work will require the services of an
electrical consultant.
The obsolete capped curbs, vent stacks, and sleeper curbs will be removed and deck
replacement provided where necessary. The existing access ladders will be removed,
Page 15 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
modified, and/or replaced with new OSHA-approved access ladders in order to meet
current code requirements. In addition, two new OSHA-approved roof access ladders will
be provided at two new locations that were without proper roof access. This work will
require the services of a structural consultant.
On the New Harmon Area E, the existing roof membrane and insulation will be removed
down to the existing concrete deck. A base layer of 1" rigid insulation will be mopped in
asphalt to the existing concrete deck followed by a two-ply asphalt vapor retarder. A new
fully-tapered rigid insulation system with isocyanurate insulation filler boards will follow
topped by a 1" top layer of rigid insulation and a four-ply asphalt built-up membrane with
gravel surfacing.
4 - Removal of Two Existing Boilers
After the Old Harmon renovation is completed, the two old steam boilers will no longer be
needed, since all of the heat will be provided by the newer hot water boilers. As part of
the project, these will be removed. In addition, abandoned piping which connects to the
boilers will be removed wherever they can be accessed. Openings left in walls and floors
by the removal of pipes will be patched. Concrete housekeeping pads will also be
removed, so that the floor is more useable.

c.) Relationship of the Project to the Updated Facilities
Master Plan
Among the goals of the 2011 MCTC Master Plan is reducing the asset preservation
backlog. And among the top priority HEAPR projects is energy system improvement.
Among the strategic goals of MCTC is to reduce energy consumption by at least 20% and
to reduce the emission of greenhouse gasses. This project will help toward
accomplishing these goals. The project will eliminate two very old, inefficient steam
boilers, as well as a rooftop unit that has four condenser motors, a 30 HP blower and two
30 ton dx compressors.
d.) Other Considerations for this Project
Most of the work of this project will probably take place during the summer of 2017. It is
assumed that the renovation cannot take place while spaces are occupied. Faculty, staff
and students will need to relocate temporarily, while the work takes place. The HVAC
might need to be separated into stages, as described in Section 7, “Schedule”, with some
of the renovation taking place after the summer. The roof work on New Harmon would
happen during the summer, after the old rooftop unit is removed. At this point, the old
rooftop unit would no longer be needed. At this time, the College does not anticipate a
need to construct temporary space or lease off campus. It is assumed that space for
relocating faculty and staff offices will be available on campus.
c.) Consequences of Delayed Funding for this Project
The existing HVAC equipment is aging and in poor condition. The main heating coil has
sprung leaks. There are life-safety issues with the roof and environmental control.
Systems are inefficient, and the energy cost is higher than it needs to be. Delaying funds
will exacerbate these conditions.

4. Sustainability
a.) Opportunities for Sustainable Design Initiatives
The Minnesota Sustainable Building B3 Guidelines are applicable to all new State
buildings and to buildings larger than 10,000 square feet, which undergo major
remodeling. This project includes the continued renovation of the Old Harmon HVAC
system and the re-roofing of New Harmon, and this presents opportunities for
improvements in the areas of Energy Efficiency and Indoor Environmental Quality.
Energy Efficiency Improvements:
• The Old Harmon HVAC system will no longer use steam heat from the old health
Science boilers, and it will instead utilize hot water from the newer, more efficient
central plant boilers.
• The old, inefficient rooftop unit will no longer be used for ventilation and air
conditioning; instead new, indoor air handling units with a more modern variable
volume air distribution will be used.
• New automatic controls will provide improved zone temperature control and system
performance; the Campus building automation system will monitor and control the
systems, to help optimize their operation.
• The reroofing will improve the thermal characteristic of the roof system for New
Harmon.
Indoor Environmental Quality Improvements:
• The amount of outdoor air intake can be automatically regulated according to the
varying occupancy of spaces (demand ventilation).
• The new HVAC systems and improved zone controls will be better able to maintain
comfortable conditions; occupants will have better control of space temperatures.
This will have a distinct, positive impact on long-term sustainability and on energy
conservation. In addition, there are opportunities to use alternative energy systems, to
supplement the main energy systems, as discussed in the next section.
b.) Analysis of Alternative Energy Systems
General Information
Predesign reports for projects for State agencies are required to undergo an analysis for
including alternative energy sources, to provide at least 2 percent of the building’s annual
energy consumption. Sources to be considered are geothermal (using ground source
heat exchange), solar thermal (generating hot water), solar electric (using photovoltaic),
and wind.
Page 18 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
The Renovation at Minneapolis Community and Technical College will involve major
remodeling of about 28,300 square feet in Old Harmon. The State of Minnesota
Department of Administration B3 Benchmarking Website stores energy data for State
buildings, including MCTC. In the following analysis, the energy consumption data is
taken from these records. According to the B3 Database, the Old Harmon building
consumes about 1,535,000 kilo-watts of energy in a normal year. This includes energy
for all purposes – heating, cooling, power, lighting, domestic water heating, etc.
As part of the renovation, the new HVAC systems will incorporate sustainable design
measures which will reduce the energy consumption. It is not expected that the boilers
and chillers will change, so the energy improvements will be limited to measures which
can be taken with the air handling equipment, air terminals, and automatic controls. It is
reasonable to assume that a savings of at least 30 percent is achievable, so the required
energy for Old Harmon is expected to be 1,075,000. On this basis, the normal annual
energy load for the renovated project area (1st, 2nd, and 4th floors of Old Harmon) is
expected to be 79% of 1,075,000 or 849,000 KWH per year. The alternative energy
systems should be sized to produce an amount of energy equal to at least 2% of this
figure, or 16,980 KWH per year. Converted to BTUs, this equals about 58 million BTUs
per year.
The Clean Energy project Analysis Software of RETScreen International was used to
forecast the capacity and performance of the following systems: solar photovoltaic, solar
thermal, and wind. The analysis for a geothermal system was hand-calculated. The
software of RETScreen International was developed by Natural resources Canada, with
sponsorship by NASA, United Nations Environment Program, Renewable Energy and
Energy Efficiency Partnership, and World Bank. The software allows for input of local
weather conditions, capital costs, design costs, and local energy prices. It was specifically
designed as a decision-making tool for the analysis of renewable energy systems.
For each type of alternative energy system, a present-value cost analysis has been
performed, using the RETScreen software. Cost figures are present-day values and
include design, materials, labor, general conditions, overhead & profit, and a contingency
amount. Incentives and grants may be available to partially offset some of the capital
cost. Use of these incentives and grants are generally conditioned on ownership by
taxable entities. Analysis of eligible ownership structures and applicable incentives is
beyond the scope of this general screening of renewable energy systems. Savings are
the present value of amount of energy cost avoided by using the alternative system. The
energy required to operate the alternative systems is a small number compared with
savings, and so this has been discounted.
A Solar Photovoltaic System
A solar collector array was installed on the roof of the loading dock section of MEC. This
is only used by the instructors and students as part of a class being taught at the College.
For this analysis, a larger new solar array is assumed.
Page 19 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
An array of solar panels with photovoltaic cells could be installed on the building roof or
possibly on grade near the building. Other equipment would be required to transfer the
electrical energy to the main building system. In order to generate 16,980 KWH of
electricity per year, the array would consist of 42 panels, and would require an area of
about 742 square feet. This could produce as much as 13.4 KW under conditions of full
sunlight exposure. The total of the first costs is $137,800. The computer model
indicates an annual energy savings of 15,975 KWH and an annual dollar savings of
$1,628. The simple payback is, therefore 85 years. This does not include the cost of
additional roof structure support, if needed. It does not include additional maintenance
cost.
A Solar Thermal System
An array of solar collectors could be used to heat or preheat domestic water. These could
be installed on the building roof or possibly on grade near the building. The panels could
be the flat-plate type with water tubing inside. In addition to the solar panels and
supporting structure, the solar thermal system would include an indoor storage tank,
circulating pump, heat exchange, controls, and wiring. In order to generate 58 million
BTUs of heat per year (2%), the array would consist of 8 panels, and would require an
area of about 318 square feet. The heat collected could be as much as 66,500 BTUs per
hour. The total of the first costs is $29,450. The computer model indicates an annual
dollar savings of $458. The simple payback is, therefore 64 years.
A Wind Energy System
An array of wind-powered electric generating turbines could be installed on the building
roof or possibly on grade near the building. Other equipment would be required to transfer
the electrical energy to the main building system. In order to generate 16,000 KWH of
electricity per year, the array would consist of a single wind turbine, requiring an area of
about 200 square feet. This could produce as much as 3 KW under ideal conditions.
The total of the first costs is estimated to be $57,200. The computer model indicates an
annual energy savings of 16,000 KWH and an annual dollar savings of $1,608. The
simple payback is, therefore 36 years.
A Geothermal System
A ground-source (geothermal) heat pump system could be installed to provide a portion of
the annual heating and cooling energy consumed by Old Harmon (including lights, plug
loads, HVAC, etc.). The system would work in conjunction with the heating water and
chilled water feeds to the new air handling units serving Old Harmon. The geothermal
system would consist of a ground heat exchanger (well field) outside of the building, waterto-water heat pumps, buffer tanks, circulating pumps, piping, wiring and controls. The
balance of the heating and cooling for HVAC will be supplied by the Campus boilers and
chillers. There is limited space at the site for a well field. It could be constructed below
an existing parking lot next to the Loading Docks. There would be space for about 12
wells. In the analysis, it is assumed that the geology at this site is fairly normal, and it is
Page 20 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
estimated that a well field consisting of (12) 200-foot deep well bores could be installed. It
is estimated that this would provide sufficient ground heat exchange for about 12 Tons of
cooling effect and an equivalent amount of heat extraction. It is also estimated that this
will supply about 8% of the annual heating and cooling for the entire Old Harmon building,
and that this represents about 3.6% of the total annual energy usage of areas in Old
Harmon affected by the proposed HVAC renovation, or 30,740 KWH/year. About half of
this energy is for heating and half is for cooling, in order to maintain a balance of heat
extracted and heat rejected to the ground. During the design phase, a test bore and a soil
conductivity test should be undertaken, in order to verify the size. The overall system cost
would be approximately $86,000 including the cost of design and soil testing.
Based on
the cost of generating central plant steam ($8.40 per million BTUs output), the savings for
heating is about $2,180. Based on the average cost of electricity ($0.10 per KWH), the
annual savings for cooling is calculated to be about $7,580. The total savings is $9,760
per year. The payback period would be 9 years.

Expenditures
a.) Summary of Financial Information
A summary of capital expenditures for this project is shown in Table 1, on the next
page of this Predesign Report. More detail is presented in Appendix A. Table 1
includes project schedule information, and more detail is presented in the chart in
Section 7, “Schedule”.
b.) Funding Sources
The construction will be funded with HEAPA money.
will be funded with the general operating budget
Temporary relocation of people
c.) GESCs and HEAPR
As a result of the governor’s executive order 11-12, MnSCU has been encouraged to
consider all building energy efficiency projects as candidates for guaranteed energy
savings contracts before including them in a HEAPR request. As part of the Predesign,
research was conducted to determine the eligibility of each of the major project
components. In a conversation with the GESP Program Manager at the State Dept. of
Commerce, it was determined that the reroofing and the boiler demolition would not be
eligible for the GES contract and will need to be covered by HEAPR funds. The HVAC
renovation probably also needs to be covered by HEAPR funds, unless the payback
period is attractive (or attractive if it is bundled together with other projects); then it
possibly could be eligible for the guaranteed energy savings contract.

6. Financial Information – Ongoing
Operating Expenditures
a.) Utility Costs
The B3 Database for buildings at MCTC shows that Old Harmon consumed the following
amount of fuel and electricity for the 12 months prior to the start of this predesign:
Electrical usage and cost:
One electrical meter for Old Harmon (1300 Hennepin Ave.) Old Harmon Electrical
(9/12/2013 to 9/14/2014) = 516,400 KWH; $50,540 = $0.10/KWH. With a total of 35,490
GSF, the average cost of electricity per square foot is presently $1.42 per year in Old
Harmon.
Natural gas usage and cost:
Three Meters for Old Harmon:
1.) 1300 Harmon Place: (09/03/2013 to 09/03/2014) = 1,260 Therms; $1,202 =
$0.96/Therm
2.) 1301 Hennepin Avenue #1: (09/03/2013 to 09/03/2014) = 2,290 Therms; $2,139 =
$0.93/Therm
3.) 1301 Hennepin Avenue #2: (10/01/2013 to 09/30/2014) = 29,990 Therms; $21,776 =
$0.73/Therm
Total = 33,540 Therms; $25,117 = $0.75/Therm, or $7.50 per million BTUs input
(average).
This is equal to $8.40 per million BTUs system output, using 89% as the average heating
efficiency. With a total of 35,490 GSF, the average cost per square foot for natural gas is
presently $0.71 per year in Old Harmon.
Post-project estimate of electricity consumption and cost (adjusted):
According to weather data, there were 760 cooling degrees days in Minneapolis during
this 12-month period. In an average year there are 1064 cooling degree days in
Minneapolis. It is estimated that approximately 35% of the electricity consumed is for
summer air conditioning, and the other 65% is for lights, plug loads, and equipment.
Normalizing the electricity consumption results in a normal building consumption of (0.65 x
516,400) + (0.35 x 516,400 x 1064/760) = 588,700 KWH/Year. As explained in section 4,
Sustainability, implementation of the energy conservation measures in this project will
reduce the amount of electricity consumption in a normal year significantly. A reduction of
30% is reasonable. Therefore, the electricity consumption in a normal year is expected to
be about 70% of 588,700 KWH = 412,100 KWH. Using the average cost per KWH in
2014, the present cost of electricity in a normal year following construction would be $0.10
x 412,100 = a projected $41,200 per year for electricity. However, the unit cost of
electricity is likely to escalate, raising this figure over time. And changing weather
conditions from year to year will also be a major factor.
Page 24 of 31
Predesign Report for Minneapolis Community and Technical College
MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
Post-project estimate of natural gas consumption and cost (adjusted):
According to weather data, there were 8658 (base 65F) heating degrees days in
Minneapolis during this 12-month period. In an average year there are 7877 heating
degree days in Minneapolis. It is estimated that approximately 90% of the natural gas
consumed is for winter heating of the structure and the other 10% is process (domestic
water). Normalizing the heating consumption results in a normal building heating
consumption of (0.10 x 33,540) + (0.9 x 33,540 x 7877/8658) = 30,820 Therms. As
explained in section 4, Sustainability, implementation of the energy conservation
measures in this project will reduce the amount of natural gas consumption in a normal
year significantly. A reduction of 30% is reasonable. Therefore, the natural gas
consumption in a normal year is expected to be about 70% of 30,820 Therms = 21,570
Therms. Using the average cost per Therm in 2014, the present cost of natural gas in a
normal year following construction would be $0.75 x 21,570 = a projected $16,180 per
year for natural gas. However, the cost of natural gas is likely to escalate, raising this
figure over time. And changing weather conditions from year to year will also be a major
factor.
b.) 5-Year Projection of Operating Budgets
Removal of the old boiler and the use of the newer, more efficient boiler will have a
significant effect on operating cost. Similarly, removal of the old rooftop HVAC unit and
replacement with a more efficient variable volume system and more efficient equipment
will have the effect of reducing energy consumption and operating cost. By connecting
systems to the Campus energy management system, to monitor and control the
operations, a further reduction in operating cost is expected. No additional operating
expenditures are anticipated, and maintenance will be reduced due to the operation of
new equipment. Staffing levels will not be impacted because of the project scope. The
maintenance work load will be reduced.
Using the figures in part a) Utility Costs, above, the amount of electricity usage is expected
to be $41,200 for electricity and $16,180 for natural gas, for a total energy budget of
$57,380 per year. In a 5-year period, the present-value savings in energy amounts to
$286,900. This does not include inflation.
c.) Debt Capacity
Minneapolis Community and Technical College’s current debt is well within acceptable
parameters. No College debt from this project is expected, due to the availability of
HEAPR funding.

MEC/Old Harmon HVAC Replacement and New Harmon Reroofing
7. Schedule
It is most likely that design and construction will take place during the 2016/2017
biennium. With funding approved in June of 2016, design will take place during the
months that follow.
It is assumed that construction in Old Harmon cannot take place while the building is
occupied. The occupants will need to relocate in order for the work to take place. Time
would be needed to move out following the end of semester, and so mobilization would
begin in May 2017. It is estimated that at least 3 solid months will be required to replace
the HVAC systems. This doesn’t include commissioning and closeout. It also doesn’t
include dealing with unknown conditions. Because it is an older building, it is likely that
there will be hidden conditions that must be addressed. Therefore, it is recommended
that four to five months should be allotted for the HVAC construction. In order to
minimize the time when floors need to be vacated, the HVAC construction could take
place in two stages. The first stage would be the build-out of the fourth floor and the tie-in
to the existing third floor air handling unit. The second stage would be the HVAC
installation in the first and second floors. At the end of the first stage, the third and fourth
floors could be occupied again, while the first and second floors are being finished. This
is shown on the following schedule:

Prior to the last week of May 2017, the Contractor will prepare shop drawings, order
equipment, fabricate materials, and make other preparations for construction. The last
week of May, 2017, Old Harmon will be vacated, and the Contractor will begin demolition
and installation of equipment and materials.
The numbers of staff, faculty and students which will need to be temporarily relocated is
unclear at this time. The College believes that there will be sufficient space available in
another Campus building. Options would include the Technology Building, Helland Hall,
and the basement of New Harmon. As long as Old Harmon is unoccupied, the removal of
the old rooftop unit can take place any time after people leave. The reroofing of New
Harmon can take place after the old rooftop unit is removed. The demolition and removal
of the steam boilers can take place at any time, as long as the new heating water piping
has been installed.

COPY OF MEMO TO: Roger Broz (MCTC), Todd Peterson (EEA) and those present
The initial Predesign meeting took place today in Conference Room T1500. The following subjects
were discussed at the meeting:
The scope of the predesign was reconfirmed. It will address the following:
• Extension of the existing third floor HVAC system in Old Harmon to also serve the fourth floor of
Old Harmon
• Installation of a similar new air handling system to serve the first and second floors of Old
Harmon
• Removal of an existing rooftop unit on the roof adjacent to Old Harmon
• Replacement of a portion of the roof or the entire roof of the building where the rooftop unit is
located
• Remove the existing boilers in the Health Science basement
The MNSCU guidelines for a predesign report require an evaluation of system options. During the
discussion today, it was established that it would be impractical to install an HVAC system for Old
Harmon, other than the one which has been started with the remodeling of the third floor. This
included the installation of a central air handling which was sized and selected to also serve the fourth
floor.
The MNSCU guidelines for a predesign report also require an evaluation of alternative energy systems
such as geothermal, solar thermal and solar photovoltaic. It was pointed out in the meeting that some
structural supports were constructed on the roof for a future solar array, but that they might not
actually be practical to use. EEA will give further study to alternative energy systems.
BTR was the architectural firm for the Old Harmon third floor remodeling. They have conducted code
reviews in the past, and this information is likely to be relevant for the predesign.
It was reported in the meeting that hazardous materials have been abated from the areas of this
project.
The consultants requested a copy of the most current Facility Master Plan from MCTC.

It is our understanding that there are no plans to expand the building or to change the current building
program significantly. The academic program will, of course, be impacted due to construction
activities.
The predesign report will address the subjects of energy-efficiency and sustainability. Today we
talked about the College’s expectations for energy conservation improvement. The new systems will
be much more efficient than the original systems. It is likely that the building systems will be required
to meet the Minnesota B3/SB2030 sustainable design requirements.
A tentative schedule was proposed. A 50% draft report will be issued on October 31st. A 95% draft
report will be issued on November 26th. It is expected that, following each issue, MNSCU will spend
about two weeks reviewing the draft. A schedule for funding and construction could not be
determined today.
