Refer to 01 80 00 PERFORMANCE REQUIREMENTS. In general, apply energy recovery equipment in accordance with current edition of ASHRAE Standard 189.1 Standard for the Design of High-Performance Green Buildings: Energy Efficiency - Prescriptive Option.
The Standard 189.1 supersedes the minimum requirements in International Energy Conservation Code/ASHRAE 90.1. It requires energy recovery equipment when the system’s supply airflow rate exceeds the associated tabular values based on the climate zone and percentage of outdoor air at design conditions.
The energy recovery system effectiveness required by Standard 189.1 is also more stringent than the current minimum building code requirements.
Provisions shall be made to bypass or control the energy recovery system to permit air economizer operation as required elsewhere in the Standard 189.1.
Exceptions:
Do not apply rotary energy recovery wheels to systems with risk of cross leakage from contaminated air streams such as chemical lab fume hood exhaust or animal facilities. Use equipment with no potential for cross leakage.
Submit cost analysis and control sequence for approval prior to submission of final review drawings.
In general, any factory-assembled air handling units with energy recovery equipment shall comply with requirements in 23 73 00 AIR-HANDLING UNITS. # Link to page when it exists in directory
