Energy Model
An energy model is being developed using the [eQUEST (DOE2.2, or identify other] predictive computer
modeling software. The features of the baseline building model are determined by the existing base
building conditions at [insert building name/ location], and ASHRAE 90.1 2007 code requirements.
Improvements to this model are then made to assess energy efficiency design improvements to the
leased premises systems.
Describe the tenant design standards or business as usual design as the adjusted baseline.
Describe build-out phases if the project is a multi-floor tenant space and how the design scope differs in
each phase if applicable.
Energy Utility Rates
Utility rates have been based on [note year of collected utility bills, ideally last year full year prior to
analysis].
Electric costs used a blended rate of [$0.XX/kWh], which includes average annual base rate and
demand charges.
Steam costs were modeled per [note applicable utility company] as shown in the table below.
Note that any steam savings or penalties have been assumed to be absorbed by the owner, due
to the negotiated rate of the steam costs to the tenant (if applicable).

Energy Model Assumptions (to be adjusted/ confirmed by the tenant and/or design team):
Condition [Revise as applicable]
Confirmation / Comment
The number of people on the floor is estimated as 200 gross square feet
(including storage and corridors, but excluding unconditioned core) per
person, a typical value for this type of office space.
On a typical day, only 95% of the maximum occupancy will be present
and working on the floor. Lower occupancy is typically due to offsite
meeting, absences, and travel. For example, floor 14 is estimated as
having maximum design occupancy of 86 people but a typical day
maximum occupancy of 82 people.
The space ends occupancy at 7PM, with a few people staying until 8PM.
Most lights are turned on at 7AM and off at 7PM.
On a typical day, 90% of the installed lighting is turned on (ignoring
daylight harvesting controls but including occupancy sensors).
Preliminary Results
The design (noted above) was evaluated from the perspective of energy efficiency opportunities. Areas
of high efficiency in the current design are noted as well as areas with potential for further increasing
the energy efficiency of tenant improvements (TI).
The preliminary energy model estimates that the optimal package will yield approximately X% in annual
tenant space electric energy cost savings relative to the existing baseline conditions at [insert building
name/ location].
Note that savings will also impact the owner for central plant related energy, including chilled water,
pumping, and cooling tower fans and are noted in the table below. The tenant savings will primarily
correspond to lights, plug‐in equipment loads, and ventilation fans. Any steam related savings or
penalties have been assumed to be absorbed by the owner, due to the negotiated rate of the steam
costs to the tenant (if applicable).

Description of Tenant Driven Energy Performance Measures (EPMs):
Envelope
Note: include all energy capital improvements completed or planned by the building owner for
an adjusted baseline
Perimeter Wall Insulation
Adding insulation to the exterior walls reduces thermal heat transfer of the surface, resulting in
decreased heat gain in the perimeter spaces of the building. This measure assumes that R-20 insulation
will be added to the inside of the perimeter walls. Assume aerogel wall insulation will be added to the
premises as prior to the perimeter wall enclosure and finish (whitebox).
Window Film
Utilizing a film on the existing glazing is one way to control solar heat gain through the glass. The
baseline glass has a U-Value of 0.60, and a Solar Heat Gain Coefficient of 0.70. Using a film would
reduce the SHGC to 0.50. This run in the analysis has assumed that film would be utilized for Levels 1621 as part of the tenant fit-out.
Window Replacement / Retrofit
Replacing the existing glass with a higher efficiency glass would also provide energy savings associated
with the reduced solar load and increased glazing insulation. The baseline glass has a U-Value of 0.60,
and a Solar Heat Gain Coefficient of 0.70. The replacement glass has been assumed to have a U-Value of
0.167 and a SHGC of 0.40.

Plug-In Equipment Load Reduction
Plug Load Control - Computer Software
Specialized computer software automatically backs up computers and shuts down computers to save
energy during unoccupied periods. This analysis assumes that the use of the computer power control
software combined with the off hours plug load control the plug-in equipment loads will be reduced by
50% during unoccupied hours.

Plug Load Control - Occupancy Sensors
Typically, plug loads are reduced at night but not to zero. Many plug loads continue to draw power, at a
reduced rate, when they are in sleep or off mode. One approach to minimizing these phantom loads is
to provide some number of outlets with active control that turns off power completely when the space
is unoccupied. This analysis assumes that plug‐in equipment will be reduced by 10% during occupied
hours, and combined with the Night Watchman controls will reduce plug-in equipment loads by 50%
during unoccupied hours.

Server Equipment/ IT Network Optimization
The implementation of the measure may be a combination of specifying Energy Star servers, right sizing
server equipment, virtualization and data distribution technologies such as a passive optical network
(PON). The reduction in electrical use would result in savings from the equipment power load and as
well as reduced computer room air conditioning and cooling load. A comprehensive design study would
be needed to investigate the design and implications of the measure.
High Efficiency Servers
Existing building server and IT loads have been estimated for the IDF/MDF rooms as 30-50 W/sf. Use of
high efficiency server equipment could reduce these loads significantly. This analysis assumes that IT
loads have been reduced by 50% as part of the tenant fit-out.
