ASHRAE 90.1 CLIMATE ZONES SERIES
The third series of Guides provide recommendations for achieving zero energy buildings. Each 50% Guide addresses a specific building type. The second series of Guides have an energy savings of 50% over 90.1-2004. Each 30% Guide addresses a specific building type. The original series of Guides have an energy savings target of 30% over 90.1-1999. The partnership agreement between the organizations can be viewed here:Īdvanced Energy Design Guides (AIA, ASHRAE, IES, USGBC) (PDF) The New Building Institute (NBI) participated in the development of the initial Guide. Green Building Council (USGBC), and the U.S. The Guides have been developed in collaboration with these partnering organizations: The American Institute of Architects (AIA), the Illuminating Engineering Society (IES), the U.S. A zero energy building is defined as a building that, on an annual basis, draws from outside resources equal or less energy than it provides using on-site, renewable energy sources.

The Advanced Energy Design Guides (AEDGs) are a series of publications designed to provide recommendations for achieving zero energy buildings or building energy savings over the minimum code requirements of ANSI/ASHRAE/IES Standard 90.1. These documents contain additional details about the analysis and development process.Īdditional Tools and Resources AEDG Toolkit

If the AHJ chooses not to establish climatic values, the building designer must obtain the climatic values by selecting the appropriate values from Table C-2 of the BC Building Code and by contacting Atmospheric Environment Service, Environment Canada, 4905 Dufferin Street, Toronto, Ontario M3H 5T4, 41.All of the 30% Advanced Energy Design Guides have a corresponding Technical Support Document prepared by the National Lab that did the analysis for the development of that Guide. It would be reasonable if an AHJ established a set of these three values and likewise apply them broadly within their jurisdiction. Alternatively, the AHJ can obtain raw climatic data from select weather stations (available on Environment Canada’s website: and map appropriate values based on geographic proximity and local experience. These values can be modelled by Environment Canada based on latitude and longitude as a fee-based service. Values for cooling degree-days above 10☌, monthly mean temperature, and monthly precipitation however are not provided in Table C-2.

A common approach is for AHJs to use Heating Degree-Days below 18☌ from listed locations (or in the absence of a specific listing, neighbouring locations) within Table C-2 Design Data for Selected Locations in Canada of the BC Building Code, and apply them broadly to all construction within their jurisdiction2.

The BC Building Code states that the authority having jurisdiction (AHJ) can establish climatic values1 for use in the calculation formula provided in Table B-4. The assigned Climate Zone dictates energy efficiency requirements appropriate to the locations. Table B-4 International Climate Zone Definitions in ASHRAE 90.1-2010 (see Appendix) provides the calculation formula for establishing Climate Zones based on these four climatic values. Thresholds for each of these climatic values have been established in order to group environmental conditions into various zones. ASHRAE 90.1-2010 requires four climatic values to define the environmental conditions of a proposed building location:
