ASHRAE Releases 90.1-2010–Part 2: Lighting Controls

ASHRAE/IES 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings is published every three years to provide states and other jurisdictions with a model commercial building energy code.

Last month, the Lighting Controls Association published a guide to the new ASHRAE/IES 90.1-2010 standard, focusing on its prescriptive lighting power requirements as well as significant changes to its scope and administrative requirements.

In Part 2 of this series on the new standard, we will focus on its extensive new mandatory and optional lighting control requirements. Regarding controls, the changes are nothing short of historic.

ASHRAE/IES 90.1-2010 requires:

• automatic shutoff of indoor and outdoor lighting when not in use;
• automatic lighting shutoff now required in buildings <5,000 sq.ft. unless specifically exempted;
• automatic lighting shutoff requirements of code now required for lamp plus ballast retrofits impacting 10+% of the connected lighting load;
• occupancy sensors required for a broader range of applications
• manual-ON or auto-ON to 50% operation required for automatic controls;
• multilevel lighting in spaces using manual space controls;
• automatic multilevel lighting in certain stairwell, parking garage and other spaces;
• automatic daylight harvesting control;
• power credits providing additional lighting power allowances as an incentive for using advanced control strategies;
• functional testing of controls; and
• documentation requirements including a control narrative and maintenance schedule.
