Post Date: 06 May, 2016 Inquiry: In residential units, are the requirements of Feature 76 met if individual unit controls for heating are provided? Ruling: No, an exemption from ASHRAE 55 requirements may not be granted in residential units if individual unit controls are provided. It is typical for each unit in a multifamily residential development to have individual control over space temperatures with controls allowing occupants to adjust temperatures. In order to rely on the controllability of the systems as an alternative strategy, it must be demonstrated that the local controls allow occupants to set conditions within the unit to meet ASHRAE 55. |
