16.02 Energy and Energy Analysis
A. Energy
The University regards the reduction of energy
consumption as an important objective in all University
facilities.
To comply with the requirements of this manual, the
design shall meet the Energy Performance Index, using the
procedures detailed in the University Manual in order to
demonstrate that the design meets the energy performance
criteria.
To be fully cost effective, energy conservation measures
must be given early and careful consideration during the
design phase of a new construction project. To ensure
that energy conservation is given priority status, an
independent Energy Analyst shall be utilized. The role
of this Energy Analyst shall be to:
1. Review and coordinate all disciplines within the
design team to achieve the most optimal energy
efficient design;
2. Review architectural, mechanical, and lighting
submissions for compliance with energy guidelines
developed by the University, prior to submission to
the University;
3. Perform energy and life cycle analysis, to
influence the building design to minimize future
energy expenditures, and to achieve the
University's desired energy budget;
4. Attend early design meetings to address building
site, orientation, and shape as factors in energy
consumption;
5. Calculate the projected energy cost of various
design alternatives, as requested by the
University;
6. Prepare required energy reports;
In designing for energy conservation, the entire facility
shall be considered, its site and prevailing climatic
conditions. Interactions among these elements as well as
the facility's energy using systems must be taken into
account. Design elements and sub-systems must be
analyzed to arrive at the most appropriate mix of energy
conservation measures.
B. Energy Analysis
Any building includes a diverse collection of spaces and
functions with varying environmental requirements.
Therefore, a system that is both efficient and
functionally responsive shall be developed. This
includes conducting a comprehensive Energy Study of the
building and a cost/benefit analysis of available energy
saving alternatives. The following considerations have
been specifically designated for evaluation. Other such
considerations shall be investigated which affect the
quality of the building environment and the cost of
operating its system.
1. Design variations in the fenestration, thermal
resistance for the exterior surfaces, and building
geometries which take advantage of passive energy
conservation systems.
2. Systems selection contingent on life cycle cost and
compatibility with building needs. A minimum of
three different systems are to be analyzed.
3. Instrumentation of the building so that the
building automatic central control systems will
monitor and control the various components.
4. Functional zoning of the building by use and
exposure.
At the Design Development submittal stage, provide a
formal written analysis to include, but not limited to:
1. Single line, conceptualized schematic system
drawings on floor plans. All HVAC duct work shall
be drawn double line in plan view regardless of
scale.
2. Heating, ventilating, and air conditioning block
and zone load calculations.
3. Economic cost/benefit study of the system chosen
and compared to alternatives chosen.
4. A computer energy analysis of the building system's
energy consumption, operation, and maintainability
over a period of not less than five years to
compare life cycle costs for the various HVAC
systems. It is desired to obtain from this
analysis the projected cost of operation by varying
hours of use and occupancy in the computer program.
One of the following shall be used:

by having compared selected alternative mechanical systems pre-
approved by the design project manager.
Analysis will be used in systems selections. ASHRAE approved or
based programs such as Trane Tracer, York Yes III, Carrier OP Cost,

16.09 Security Egress for Individuals with Disabilities
Currently, many facilities that have handicap door openers do
not have the electronic panic bar. The handicap door opener
is activated by the handicap door switch. During the day the
door is unlocked and the opener can operate without
resistance. The door is locked at night. When the door is
locked and the latch prevents the door from opening.
Therefore, when the handicap switch is pressed, the door does
not open. This condition traps individuals with disabilities
in the building.
To alleviate this problem, the following design criteria has
been established:
A. Install an electric panic bar on each door equipped with
a handicap door opener.
B. Interface the door opener with the electric panic bar.
Reference attached specifications Power Supply
with delayed relocking module and electric latch retraction)
and drawings. In addition, reference
Section 8., Finishes and Windows (Hardware) and Section 16.,
Electrical and (Security Guidelines).

resistant enclosures, and mounts, as well as, the
possible addition of interior lights.
