As of January 1, 2017 ASHRAE 90.1 took effect in Ohio. ASHRAE 90.1 compliance applies to all new construction and retrofit projects involving alteration of >10% of lighting loads. ASHRAE is the benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 36 years.
This standard provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings. It offers the minimum energy efficiency requirements for design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as criteria for determining compliance with these requirements.
This 2016 edition comprises numerous energy-saving measures and incorporates changes from more than 125 addenda.
Key updates to ASHRAE 90.1:
1. Exterior LDP (lighting power density) requirements
2. Detailed daylighting control and skylight requirements
3. Occupancy-sensor control requirement
4. Daylighting/after hours control in parking garages
5. Emergency shutoff and stairwell control
6. Modified requirements for exterior and interior lighting power densities. (Reflecting new lighting levels in the IES Lighting Handbook).
7. Modified requirements for lighting control to add additional controls in some space types and options to others to allow easier application of advanced controls.
