ASHRAE, the U.S. Green Building Council (USGBC), and the Illuminating Engineering Society (IES) recently announced the publication of ANSI/ASHRAE/USGBC/IES Standard 189.1-2014, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings.

The standard incorporates 67 addenda. Major changes include:

Fenestration-orientation requirements were updated based on new research. Additionally, changes and updates were made to equipment-efficiency tables, ENERGY STAR references, and continuous-air-barrier requirements.
  • The updating of carbon-dioxide-emission factors for different energy sources.
  • The addition of lighting quality to the scope of the indoor-environmental-quality section, the addition of lighting-controls requirements for specific space types, the clarification of requirements for air sealing of filtration and air-cleaning equipment, and the addition of requirements for preoccupancy ventilation and building-envelope moisture management.
  • The mandating of all site-sustainability requirements; the enhancement of requirements for stormwater management; the addition of requirements for bicycle parking and preferred parking for low-emission, hybrid, and electric vehicles; and the addition of requirements for predesign assessment of native and invasive plants.
  • The addition of more-stringent water-use requirements for toilets, clothes washers, dishwashers, and green roofs.
  • The updating of requirements for recyclable-storage and collection areas, the updating of requirements for construction-waste management and life-cycle assessment, the addition of requirements for multiple-attribute-product declaration or certification, and the addition of maximum mercury-content levels for certain types of electric lamps.
  • The updating of requirements related to environmental impacts associated with idling construction vehicles and the addition of requirements to reduce the entry of airborne contaminants associated with construction areas.
