Lighting controls are rarely programmed correctly to match building occupancy schedules, and the calibration of daylight sensors must be checked prior to project completion. Experience as a commissioning agent on various new buildings, along with retro-commissioning activities in existing buildings, has shown me that lighting controls are often left to the installing contractor for verification. Jason Gerke : The proposed updates to ASHRAE 90.1 include a requirement for commissioning of lighting control systems by a person not involved in the design or construction of the project. Michael Tillou : The things in the 2010 version of the standard that I am excited about are new regulations for data center energy efficiency, specific air barrier requirements, and the move away from treating ventilation as energy neutral in recognition of the fact that good ventilation system design not only improves IAQ, but increases building energy efficiency. The Energy Compliance Budget (ECB) and Appendix G (used for LEED) modeling requirements have also been updated. In addition, there has been substantial work on control of lighting, daylighting, and HVAC systems.

This includes the building envelope, lighting power densities, power, equipment efficiencies, and HVAC and service water heating system requirements. Mick Schwedler : Since ASHRAE/IES 90.1 covers the entire building, all aspects are being addressed by addenda to the standard.

CSE: What areas-building systems, energy performance, efficient technology-does the new version of ASHRAE 90.1-2010 focus on that was not addressed by previous versions of the standard?
