Design parameters listing for required conditions for all areas, number of occupants, hours of
State the design conditions including indoor and outdoor temperatures, relative humidities for
summer and winter conditions, filtration and ventilation requirements, personnel loads, and
special equipment loads.
State the proposed building characteristics including 'U' Factors of walls, floors, roofs,
windows, etc., orientation of the building, latitude and longitude of location, and any special
conditions that would have an impact on HVAC design.
Energy budget target values, design temperatures and humidity requirements (Summer
outside design dry bulb and wet bulb temperatures, winter outside design dry bulb, indoor
design dry bulb and relative humidity range, special conditions such as room pressurization,
100% exhaust, 100% outside air, etc.). Special Services; i.e., compressed air natural gas.
Types of Equipment or systems Government does not desire; i.e., roof-top units, direct gas-
fired vs. hot water or direct heating systems, chilled water or direct expansion, no fancoil
terminals in humid areas, cooling towers on bases which demand air cooled chillers only,
pneumatic control systems not desired, etc.
List of types of equipment or systems Government requires; i.e., chilled water insulation must
be cellular glass, when single loop control systems are required, utility management and
control systems, required interface with Utility Monitoring and Control Systems (UMCS)., etc.
Monitor/Control Systems levels required.
Heat loads for Government furnished equipment
List required studies such as active solar water-heating feasibility study, life cycle cost (LCC)
study, etc. Advice offerors of the availability of Corps of Engineers' programs such as
SOLFEAS, the Corps Generic Study, and LCCID, where appropriate.
List acceptable HVAC loads programs, energy budget and life cycle cost software. Examples:
BLAST, LCCID, Trane Trace 600, Carrier HAP, etc.
List areas Requiring Fire Protection or require the Design-Build Contractor to make selection of
area fire protection requirements based upon applicable codes and standards for the use of
If fire protection system is preferred, indicate the type.
Design Criteria (including type of fixtures, lighting levels, daylighting requirements, distribution,
mechanization listing with power requirements, etc.).
