ASHRAE compliance is sweeping the nation As of July 2015, 41 out of 50 states have adopted energy code requirements that meet or exceed ASHRAE 90.1, a set of national recommendations that give states and local municipalities guidelines for writing their own energy codes. If you look at a system like LUTRON VIVE you'll get an idea about where these controls are headed. ASHRAE Standard 90.1 2010: A Beginner’s Guide. The 2013 version introduced many scenarios that makes planning for lighting controls a serious exercise. It seems like the direction ASHRAE is taking this is meant to have lighting and plug loads having a complex control logic instead of the old simple auto on/auto off lighting controls. For example, I don't believe an open plan office space is considered "enclosed by ceiling height partitions" but a private office would. Note that these apply to different spaces in different ways. Daylight sensors only work during daytime and won't help control light during night time, so I don't think the combination automatically complies (maybe a custom system would?). It needs to be either "manual on/auto off" or "auto on 50%/manual on 100%/auto off". The way I interpret this is that a simple on/off occupancy sensor doesn't comply.

under 9.4.1.2 seems to serve the same purpose for manual controls. The logic here seems to be reducing the amount of time a lighting system is turned on to 100% by requiring human intervention, otherwise it's either off or only on with half the power. AHSRAE 90.Section 9.4.1 Lighting Control states that "Any automatic control device required in sections 9.4.1.1, 9.4.1.2, and 9.4.1.6 shall either be manual on or shall be controlled to automatically turn the lighting on to not more than 50% power, except in.". ASHRAE 90.1-2007 required automatic shutoff for interior and exterior lights if more than 50% of the lighting design was included in the project.Daylighting is required if the building has 250SF or more side lighting and/or more than 900SF of top-lighting.However the allowance for corridors went from 0.5 (ASHRAE 90.1-2007) to 0.66 (ASHRAE 90.1-2010).

To achieve the prerequisites for Options 2 and 3, your project must follow ASHRAE 90.1-2010 mandatory and prescriptive requirements.This represents an expected savings of 50% over ASHRAE 90.1-2004. For Option 2, LEED now includes a prerequisite that the standard for compliance uses the 50% savings version of the Advanced Energy Design Guides (AEDG) instead of the 30% savings version of the AEDG.For data centers, USGBC requires that building power and cooling infrastructure provides 2% of the required 5% energy cost reductions.USGBC now requires you to achieve prerequisite compliance without accounting for the cost of generating renewable energy onsite Proposed addendum ch to ANSI/ASHRAE/IES Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings, changes the requirements.Process energy no longer has to make up 25% of the overall building energy for your baseline and proposed simulation models.ASHRAE 90.1-2007 has been updated to ASHRAE 90.1-2010 2010 ASHRAE Standard 90.1-2010 Incorporated 109 addenda aimed at reducing energy costs by 30 compared to the 2004 version.For your convenience, we have summarized the major changes below. LEED has updated to version 4, and that means the ASHRAE referenced standard has some updates as well.
