RECOMMENDATION
Recommendations
Supplementary Information
Engage a Commissioning Authority.
Commissioning serves to verify the performance of completed systems and
determine whether or not they comply with the design concept and the
specified performance ratings. The commissioning process should have
begun during the early stages, where decisions would have been made as to
which systems would be commissioned. Later, the performance requirements
should have been established. At the Construction Documents Stage, the
commissioning plan, and construction documents should be reviewed,
preferably by someone other than the Designer.
Include Commissioning requirements in the
Construction Documentation.

RECOMMENDATION
Recommendations
Supplementary Information
Provide a stormwater management plan to prevent
damage to project elements, including vegetation,
on this and neighboring sites. Include an
engineering design of the site drainage pattern,
including volume calculations and site
management strategies. Aim for no increase in runoff. Or, if the site already consists of more than
50% impervious surface in its pre-development
state, aim for a reduction of 25% in storm water
run-off.
Develop design strategies that minimize disturbances to the site's watershed.
Control stormwater run-off and promote groundwater percolation for irrigation
and to recharge aquifers. Minimize stormwater run-off into rivers, streams,
lakes or sewers by:
minimizing hardscapes and maximizing the use of permeable, pervious
surface paving materials,
storing water in catchment systems (barrels or cisterns),
increasing vegetation to maximize the total amount of water consumed by
plants,
integrating storage area ponds, surface stormwater retention areas, rock
marshes, drywells and infiltration basins where water can seep into the
ground,
grading the site to direct water flow, and landscaping the site to divert water
away from the building.
Enhancement of site ecology

Opportunities for improvement
Northside Dining Terrace pg. 9
RECOMMENDATION
Recommendations
Supplementary Information
Ensure that the projected energy consumption
meets or exceeds the preset energy-use targets.
Include the energy performance requirements in
the specifications.
Simulations should have been done at the Design Development Stage, using
tools such as EQuest or DOE 2.0 programs. Modeling of different HVAC and
lighting options should have been reviewed and refined to determine the most
efficient solution to meet or exceed the ASHRAE 90.1-2004 standard. This
standard focuses on improving the energy consumption performance of
commercial buildings based on both the building envelope and the building
systems and equipment.
Control strategies and sizing of the systems should have been carefully
evaluated to avoid over-specification. Post occupancy operation and
maintenance requirements should also have been considered.
Energy demand minimization
Summary of Your Achievements
Space optimization
The floor area has been optimized to efficiently fulfill the building's functional and spatial requirements while minimizing the amount of
space that needs to be heated and cooled (i.e. kitchen and utility equipment is separated from other areas ).
Response to microclimate and topography
The building is located and oriented on the site to optimize the effect of microclimatic conditions for heating or cooling (i.e. building is
south facing to optimize the heat in winter months with deep overhang to minimize heat gain in summer months. ).
Opportunities offered by the site topography, and design measures – including location and orientation – are optimized to provide
shelter against wind and snow deposition.
Integration of daylighting
The amount of daylighting is optimized through building orientation and window-to-wall size ratios (i.e. window wall optimizes natural
light with provision of sun shading ).
The indicated visible transmittance(VT) of the window glazing is 0.7.
Northside Dining Terrace pg. 10
Building envelope
The thermal resistance of the exterior enclosure meets Building Energy Code levels. The reported thermal resistance (R) of the roof is

Supplementary Information
If possible, phase the construction process.
Buildings are often designed with additional space to accommodate potential or
future expansion, based on projections that may or may not prove accurate.
Resources can be spared if entire parts of a project are never built. By planning
to build in phases, only the parts of a project that are needed at a given time will
be constructed. Drawings should indicate the various potential phases.

than indoor air.
Integration of daylighting
RECOMMENDATION
Recommendations
Supplementary Information
Provide specifications for daylighting systems,
integrated electrical lighting and daylighting
control systems. An account of the daily and
seasonal variations should be included in the
construction documents. Provide the modeling
results and manufacturers' information on the
lighting controls. Develop an operating manual
to ensure that appropriate adjustments can be
made to the lighting systems to account for
daily and seasonal changes.
Natural light entering the building should be integrated with electrical light, taking
into account daily and seasonal variations. Zones with daylighting potential
should have light-sensing controls to adjust electric lighting in response to
available daylight. Failure to provide these can produce less than optimal
results. For example, on days when daylighting alone can provide sufficient light
for most office activities, occupants may experience eye strain due to excessive
light levels if electrical lights are not dimmed. Energy is also wasted on
unnecessary artificial lighting and the air-conditioning needed to counter the
heat from lights.
Daylight control systems can save up to 60% in lighting energy. They include
dimming and switching. Dimming controls vary the light output over a large
range to provide the desired light level, while switching controls turn individual
lamps off or on as required. Dimming systems require electronically dimmable
ballasts. Although they are more expensive than switching systems, they
achieve the largest savings and do not abruptly change light levels as do
switching systems.
Note that the use of daylight control systems is still relatively rare in America.
Care must be taken to ensure proper design and commissioning, otherwise
energy-savings may be minimal and the controls are likely to be de-activated.
Building envelope

Detail the continuous air/vapor barrier and
show how it will avoid thermal bridging,
provide thermal comfort to the occupants and
prevent condensation in the building. Include
product data on air/vapor barrier materials.
A continuous air barrier helps to ensure the integrity of the building envelope,
thereby eliminating thermal bridging and preventing condensation, avoiding air
leakage, reducing the energy needed for heating and cooling, and avoiding
water damage to the building envelope, interior walls and ceilings. Airtight
commercial construction involves a systematic approach to providing continuity
of an air barrier in the building envelope, including areas where dissimilar
materials meet. This is of particular significance to residential buildings.
Follow the best air/vapor barrier practices by:
Ensuring that drawings provide air barrier detailing of roof to wall air barrier
connection and other details such as between different wall types, air barrier
penetrations, and wall to glazing systems.
Considering the building occupancy requirements for relative humidity,
temperature, and interior pressures in the design of the air and vapor barrier
systems.
Considering material compatibility issues.
Requiring mock-ups and mock-up testing for air and vapor barrier systems.
Requiring lab testing for air and vapor barrier systems.
Requiring field review and testing by a building envelope specialist.
Optimizing the mechanical systems been for designed building air leakage.
Review is required for the most likely areas for air leakage, such as joints
between the roof and wall air barriers, the area between the wall air barrier and
the windows and doors, and between the wall air barrier and the grade beam,
and, in residential buildings - balconies.
Other high risk areas are penetrations of the wall and roof air barriers by
electrical, plumbing, telecommunication services, trusses, beams, chimneys and
ventilation ducts; joints at the floor level in multi-story buildings; and poor quality
or poorly adjusted weather strips on doors and windows.

Supplementary Information
In addition to a water meter to measure the total
amount of water supplied to the building, major
water consumption operations such as boilers,
cooling tower make-up lines, water-cooled airconditioning units or special laboratory operations,
should also be individually monitored.
Metering provides continuous information of system efficiency and can give
early warnings of system problems such as leaks. When each tenancy is

dishwashers (conveyor) which use 120 gallons/hour); etc.
Minimal use of water for irrigation
RECOMMENDATION
Recommendations
Supplementary Information
Specify irrigation using non-potable water (i.e.
captured rainwater or recycled site water). If
rainwater will be used, ensure that there is a
system for catchment, storage and distribution.
Collected rainwater and graywater or treated wastewater can be reused for
irrigation. Rainwater can be collected with a cistern or in rain barrels at each
rainwater leader or downspout. Manufactured rain barrels range from 40 to 80
G. They should incorporate a “roof washer” or a “first flush” device, to avoid
contamination by bird droppings and dust, an inlet screen and an overflow
outlet.
Northside Dining Terrace pg. 17
Most roofing materials are suitable for rainwater collection, except for
redwood, cedar or treated wood shingles and shakes and asphalt shingles,
which leach toxic materials when wet. Food-producing gardens should not be
watered with rainwater from roofs covered with these materials.
Consider graywater reuse technologies, if local codes permit, and if sufficient
water is generated from baths, showers, bathroom sinks and washing
machines. Wastewater can only be used after proper treatment to remove
solids and to meet predefined and/or regulated bacterial levels. Graywater
collection and irrigation systems must be considered early in the design
process, since they will affect landscaping design and the size and placement
of mechanical spaces.

RECOMMENDATION
Recommendations
Supplementary Information
Specify materials with low embodied energy.
Provide evidence that the foundations, floor,
structural system (column and beam, or post and
beam combinations), roof and envelope (cladding,
windows etc.) assembly materials have undergone
a life cycle assessment. The specifications should
reflect the results of the “best run” life cycle
assessment of the building's materials. “Best run”
here means the specification with the lowest life
cycle impact out of the number of the alternatives
investigated. In Division 1, state the project's
environmental goals and the general environmental
procedures with regards to material selection and
specification.
A lifecycle assessment (LCA) is considered to be the most reliable way to
calculate and compare the cradle-to-grave environmental effects of common
building materials. Designers can use modeling tools such as Athena™ to
examine the lifecycle environmental effects of a complete structure or of
individual assemblies, and can experiment with alternative designs and
different material mixes to arrive at the best environmental footprint. The
objective of the simulation is to aid the Designer in selecting building
assemblies with the lowest reported impact in terms of energy consumption,
air and water toxicity index, global warming potential (GWP), ecologically
weighted resource use, and solid waste emissions.
Materials that minimize consumption resources
Summary of Your Achievements

RECOMMENDATION
Recommendations
Supplementary Information
Specify materials high in recycled content such as
crushed aggregate, carpets with fibers made of
recycled content, ceiling tiles and metal products.
Avoid materials where the recycled content may
compromise the IAQ or service performance.
Reference recycled-content standards, regulations
and requirements. Provide material specifications
which reflect the results of a life cycle assessment
and post-consumer content. In Division 1, state the
project's environmental goals and the general
environmental procedures that address materials
with recycled-content. In
eachCSI/Masterformat technical section, provide
specific recycled-content percentages for postindustrial or post-consumer material. Document the
rationale for using recycled materials, in terms of
recycled content, embodied energy, durability, etc.
For public bid projects, provide three different
manufacturers.
Where practical, use materials high in recycled content. True recycled content
consists of materials that have been used and then recycled (i.e. postconsumer), as opposed to materials that are recycled within the industry itself.
Examples of post-consumer materials are crushed aggregate carpets with
recycled content in the fibers and backing, ceiling tiles and metal products.
Avoid recycled materials where the recycled content or recycled product could
compromise IAQ or service performance.
RECOMMENDATION
Recommendations
Supplementary Information
Maximize the use of locally manufactured products
and materials (produced within 500 miles of the
site) as they generally require less energy for
transportation and should therefore be cost
competitive over materials from a more distant
source. A target of 25% of the total percentage of
products or materials should be locally
manufactured or be from renewable sources.
Documentation of locally manufactured materials
should reflect the results of their life cycle
assessment.
Transportation consumes energy and generates pollution. Therefore locally
produced materials (i.e. those manufactured within a 250-500 mile radius of
the project site) are likely to have lower embodied energy. Since price reflects
transportation charges, they may also be cheaper than those produced farther
away. Weight and volume minimization can also significantly lower the
environmental impact of transportation. Consider foldable or stackable designs
and final product assembly at the retail location or by the end-user.
Where feasible, specify renewable materials such
as cork, and bamboo. Before making the final
selection, conduct a life cycle assessment using a
tool such as Athena™ Environmental Resource
Guide or BEES™.
Design strategies to avoid waste during construction can also save on
transportation. For example, modularity and standard sizes promote efficient
use of materials and construction methods, and reduce off-cuts of lumber,
wallboard, and other materials.
Consider renewable sources such as wheat, cotton, wood, cork, and bamboo.
The final selection should be based on a life cycle assessment using a tool
such as Athena™ Environmental Resource Guide or BEES™, to evaluate the
environmental impacts of extracting, harvesting, or mining raw materials and
shipping them.

suppliers regarding the composition of the woodbased panel products and/or certification ((SFI),
(FSC), (ATFS), (CSA-SFM)) that the wood
products have been monitored from origin to end
consumer. In Division 1, state the project's
environmental goals and the general environmental
procedures that address certified sustainable
wood. In Divisions 6, 9, and 12, list at least three
different suppliers of certified wood.
The use of tropical hardwoods should be avoided, as their preservation is
critical for maintaining the biodiversity and survival of some of the most varied
ecosystems on earth. Where structural/envelope systems require wood
products, these should be certified through sustainable forestry management
programs such as the Sustainable Forestry Initiative (SFI), the Forest
Stewardship Council (FSC), the American Tree Farm System (ATFS) and the
CSA International Sustainable Forest Management program (CSA-SFM). The
American forest industry actively supports the development of consensusbased sustainable forestry certification standards to help ensure that wood
used in products is derived from environmentally sound and sustainable
forestry operations. Under these programs, forests or woodlands are
inspected to see if they are being managed according to criteria with regard to
the scale and intensity of forest management operations, taking into account
their uniqueness and ecological fragility.

Opportunities for improvement
RECOMMENDATION
Recommendations
Supplementary Information
To avoid re-entrainment, position air intakes and
outlets at least 33 ft apart, and ensure that inlets
will not be downwind of outlets.
Indoor air quality (IAQ) is primarily related to the quality of the outside air. If
the site is located relatively distant from heavy urban and industrial pollution,
the outdoor air should contain no more than 350-400 ppm of CO2. However,
even in locations where the outdoor air is of relatively high quality, the building
can be contaminated by localized sources of pollution.
One way to avoid some of these problems is to place outdoor air intakes high
up, where there may be less pollution than at ground level, although even at
higher elevations, care must be taken to prevent contamination by insects or
bird droppings. Prevailing winds and airflow patterns created by the building
can have a considerable impact on the air that actually reaches the air intakes.
When air intakes are unavoidably located close to sources of pollution, or
where the airflow is obstructed, additional measures to remove pollutants from
the supply air will be required. Air intakes should be separated from potential
sources of pollution by the following minimum separation distances:

Ensure that the mechanical systems will provide
effective air exchange. One way of determining
effective mechanical ventilation is through
measurements of air exchange effectiveness (E) as
determined by ASHRAE 129 - 1997 Measuring AirChange Effectiveness. This compares the age of
the air the occupants breathe to the age of the air
that would reach the occupants throughout the test
space if the indoor air were perfectly mixed. For
mechanically ventilated buildings, well-designed
ventilation systems should result in an E-value
greater than or equal to 0.9. For naturally ventilated
spaces, demonstrate a distribution and laminar flow
pattern that involves not less than 90% of the room
or zone area in the direction of airflow for at least
95% of the hours of occupancy. In the case of
standard HVAC systems, the construction
documents should summarize all the calculations,
indicating that the ventilation systems will be
capable of achieving these requirements.
Ventilation effectiveness addresses not only the provision of adequate
ventilation but also the distribution of “well-mixed” air within the
space. ASHRAE 62.1-2004 defines “ventilation effectiveness” as the fraction
of the outdoor air delivered to the space that actually reaches the occupants.
The objective is to ensure good air distribution; with free airflow and that the
outdoor air does not bypass the occupants' breathing zones.

Supplementary Information
Specify that personal control over the ventilation
rates will be provided for a maximum of four to six
occupants, either through personalized HVAC
controls or, for naturally ventilated buildings,
operable windows or operable trickle vents.
Providing individual control over the environmental conditions in the workplace
helps increase occupant satisfaction and productivity. Task/ambient
conditioning (TAC) systems allow occupants to control temperature, airflow,
and in some cases, lighting and sound levels to meet their individual needs. In
perimeter areas, consider a combination of TAC control and operable
windows. In non-perimeter areas, provide VAV systems with a 1:1:2 terminal
box to controller to occupant ratio. This technology is often implemented in
conjunction with under-floor air distribution, a combined approach which has
the potential to improve thermal comfort and IAQ, while simultaneously
reducing energy use and lifecycle building costs, and reducing the floor-tofloor height requirements in new construction.
