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.

Get your 'Early Bird' entry in for BD+C 30th Annual Reconstruction Awards
The deadline is for BD+C's 30th Annual Reconstruction Awards is July 19, but if you get me a draft of your entry by July 12 (earlier if possible, please!), we'll read it and give you feedback and suggestions that could help you win. We'll give you enough time to rework your entry in time to meet the deadline. We do this "Early Bird" service to help you put together the best possible entry - one that will answer any questions our distinguished jury members may come up with. However, we must emphasize that the BD+C Reconstruction Awards program is a juried competition, so there are no guarantees you'll win. We're just trying to improve your odds. Building Design+Construction is the only publication in its field to recognize the importance of reconstruction in all its forms - historic preservation, adaptive reuse, renovation, fitouts, and reconstruction with addition. And we've been doing it for 30 years. Incidentally, reconstruction accounts for 30-35% of all revenue for AEC firms, so it's a key component of the US/Canada design and construction industry. Send your draft entry to: rcassidy@sgcmail.com. And good luck!
