The following list provides more detailed descriptions of the requirements in Section 4 of the Mechanical Compliance
Certificate.
Requirements Specific To: HVAC System 1
1. The specified heating and/or cooling equipment is covered by the ASHRAE 90.1 Code and must meet the following minimum
efficiency: Heat Pump: 6.8 HSPF, 10.0 SEER
2. Heat pumps having supplementary electric resistance heat must have controls that, except during defrost, prevent supplementary
heat operation when the heat pump can meet the heating load.
Requirements Specific To: Storage Water Heater 1
1. Piping for the specified circulating service hot water system must be insulated with a minimum of 1-in. insulation having a
conductivity no >0.28 Btu-in/(h-ft2-degrees F).
2. Circulating service hot water systems must have a time switch control that can automatically turn off the system during unoccupied
hours.
3. Service water heating equipment used solely for heating potable water, pool heaters, and hot water storage tanks must meet the
following miniumum efficiency: Gas Storage Water Heater efficiency >= 0.43 EF
Generic Requirements: Must be met by all systems to which the requirement is applicable:
1. Design heating and cooling loads for the building must be determined using procedures in the ASHRAE Handbook of Fundamentals
or an approved equivalent calculation procedure.
2. All equipment and systems must be sized to be no greater than needed to meet calculated loads. A single piece of equipment
providing both heating and cooling must satisfy this provision for one function with the capacity for the other function as small as
possible, within available equipment options.

6. Outdoor -air supply systems with design airflow rates >3,000 cfm of outdoor air and all exhaust systems must have dampers that are
automatically closed while the equipment is not operating.
7. The system must supply outside ventilation air as required by Chapter 4 of the International Mechanical Code. If the ventilation
