The 2016 version of ANSI/ASHRAE/IES Standard 90.1, the Energy Standard for Buildings Except Low-Rise Residential Buildings, was recently released.
The update includes a new compliance path and significant technical changes affecting building envelope, and mechanical and lighting systems. The document contains 121 new addenda since publication of the previous version: the 2013 standard.
The 2016 edition contains a new compliance path, the Performance Rating Method, which is included in Appendix G. The provision was previously used only to rate “beyond code” performance of buildings; it now serves as an alternative to the traditional performance path.
Among the most significant technical changes are:
Envelope:
• Mandatory requirements for envelope verification, supporting reduced air infiltration, and increased requirements for air leakage to overhead coiling doors.
• More stringent prescriptive requirements for metal building roofs and walls, fenestration, and opaque doors.
• Improved clarity of exterior walls definitions, building orientation, and clarity around the effective R-value of air spaces.
• New requirements based on the addition of climate zone 0.
Lighting:
• Modified control requirements to simplify advanced lighting control applications.
• New exterior and interior lighting power densities based on LED technology.
• Requirements for dwelling units to set limits on light source efficacy.
• Additional controls for lighting in parking areas.
Mechanical:
• Chilled water plant metering, requiring large electric driven chilled water plants to be monitored for electric energy use and efficiency.
• DOAS requirements, adding efficiency and rating requirements for dedicated outside air systems.
• Elevator efficiency, introducing requirements for identifying usage category and efficiency class.
• Economizer fault detection and diagnostics, implementing monitoring system requirements for air-cooled DX cooling units with economizers, helping to ensure that equipment is working properly.
• New requirements for replacement equipment, such as adding economizers or fan speed control, which previously only applied to new installations.
