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 and certificates to
obtain PEPCO rebates and for other purposes.
In addition, the University intends to take advantage of
PEPCO's New Building Design Program whenever it is cost
effective to do so. Accordingly, a design study or
building simulation based upon the requirements of the
PEPCO New Building Design Program, Option 1,
Comprehensive Incentive Plan shall be provided. A list
of the conservation technologies to be included in the
study are to be submitted to the University during the

shall be submitted to PEPCO including application forms.
Besides the information which PEPCO requires, the study
shall provide life cycle costing, to include cost
comparisons between standard equipment and building
components and those recommended, energy and PEPCO
incentive savings, and simple payback.
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.

16. SECURITY EGRESS SYSTEM FOR INDIVIDUALS WITH DISABILITIES
(5.1.96)
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 (MPB-851 Mini Power Supply
with delayed relocking module and electric latch retraction)
and drawings (No. 9510-3 and 9510-4). In addition, reference
Section 8., Finishes and Windows (Hardware) and Section 16.,

specified by proprietary name, trade name, or
manufacturer, it is considered that the items named,
are intended to be used.
2. Group 2: When the material or equipment is specified
with the phrase "... or approved equal ..." after a
brand name and other identifying information it is
intended that the brand name is for the purpose of
establishing a minimum acceptable standard of quality
and performance and the Contractor may base his bid
proposal on any item which is in all respects equal to
or better than that specified and essentially would be
the same in appearance, in size, in operation, in
performance, and will fit in the available space.
3. Group 3: When material is specified as complying with
the requirements of a published "Standard
Specification" of a trade association such as, ANSI,
ASTM, government specifications, etc., the contractor
shall base his proposal on any item which can be shown
to comply in all respects with the referred "Standard
Specification."
D. It is distinctly understood: (1) that the University or
their designated representative will use their own judgment
in determining whether or not any materials, equipment or
methods offered for approval as an equal are in fact equal
to those specified and will fit the space available; (2)
that the decision of the University on all such questions
of equality is final; and (3) all acceptable material,
equipment or methods will be provided at no increase in
cost to the University.
E. Upon receipt of written notice from the University or their
designated representative that the material, equipment, or
methods have been reviewed and accepted (with no exceptions
taken or comments as noted thereon), the Contractor may
proceed with the accepted equal material, equipment, or
methods. The Contractor shall assume full responsibility
for and performance of any change or adjustment in the
construction that may be required by the use of such
materials, equipment, or methods. This shall include but
