Standards & Codes

ASHRAE Standards
Standard 90.1-2004
The purpose of this standard is to provide minimum requirements for the energy-efficient design of buildings except low-rise residential buildings.

Standard 55-2004
The purpose of this standard is to specify the combinations of indoor thermal environmental factors and personal factors that will produce thermal environmental conditions acceptable to a majority of the occupants within the space.

Standard 62.1-2007
The purpose of this standard is to specify minimum ventilation rates and other measures intended to provide indoor air quality that is acceptable to human occupants and that minimizes adverse health effects. This standard is intended for regulatory application to new buildings, additions to existing buildings, and those changes to existing buildings that are identified in the body of the standard. This standard is intended to be used to guide the improvement of indoor air quality in existing buildings.

Proposed Standard 189.1-2
The purpose of this standard is to provide minimum requirements for the design of high-performance, green buildings to:

  • Balance environmental responsibility, resource efficiency, occupant comfort and well being, and community sensitivity, and
  • Support the goal of the development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
  • Design, Construction and Operation of Green High Performance Healthcare Facilities

LEED Energy and Atmosphere
The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ is the nationally accepted benchmark for the design, construction and operation of high-performance green buildings. LEED provides building owners and operators with a tool that provides immediate and measureable impact on their buildings' performance. Energy efficiency is covered under the Energy and Atmosphere section of the rating. Additional energy savings (but not points) result from some of the strategies covered under "Sustainable Sites" and "Indoor Environmental Quality".

The Living Building Challenge
The Living Building Challenge, being developed by the Cascadia Chapter of the USGBC, is a performance based standard that aims to challenge all building owners, architects, engineers and design professionals to move beyond LEED Platinum. It is an evolving tool and specific rules on how to document compliance and to seek living building designation will be presented in the document The Living Building User's Guide. The requirements are all based on actual measured outcomes or actual performance - not what a project is proposed to be. There are no optional credits, only prerequisites.

Advanced Buildings Core Performance
The Core Performance Guide outlines a step-by-step simplified approach to achieve predictable energy savings in small- to medium-sized buildings without the need for modeling. The Guide is the new version of Benchmark 1.1, a nationally recognized resource on how to deliver best-in-class energy efficiency and indoor environmental quality in high performance commercial buildings. It is aimed at small to medium sized buildings (under 70,000 square feet) but also has some application in larger more complicated buildings.
