General advances in lighting technology are expected to make up this difference. These are fairly common practice today with the former being a simplified approach, and the latter providing additional flexibility.Ĭhanges to the building area method lighting power densities (LPDs) have averaged a 16 per cent reduction as the limits for many building types have been lowered, or at least maintained. There are two approaches to achieve compliance with the interior lighting power limits detailed in ASHRAE 90.1-2010-calculation of total load (measured in Watts per square foot) using either the building area method or the space-by-space method of calculation.

However, while power density reductions were imposed both indoors and out, lighting controls are the major focus of extra energy efficiency requirements. Lighting systems will continue to feel downward pressure on power densities, with the general expectation that solid-state light-emitting diode (LED) technology will continue to provide necessary efficacy improvements. Mohawk College in Hamilton, Ont., contains energy-efficient lighting, daylighting, and a green wall. It has also fundamentally modified its scope beyond just design and construction to energy-efficient operations and maintenance. This prescriptive method of achieving compliance includes more than 40 lighting addenda-as compared to the 2007 version-and has made ASHRAE 90.1-2010 one of the most modern energy efficiency standards available. The latter option is the only one that does not require energy modelling. achieve energy efficiency levels attained by conforming to ASHRAE 90.1-2010, as modified by Supplementary Standard SB-10.exceed by not less than five per cent the energy efficiency levels attained by conforming to ASHRAE 90.1-2010 or.Accordingly, Supplementary Standard SB-10 offers the following new compliance paths: These paths reference ASHRAE 90.1, which is widely used by the North American building industry. However, it also provides additional compliance paths to achieve this level of energy efficiency. This standard requires the energy efficiency of those building types for which a permit has been applied after December 31, 2011, exceed, by at least 25 per cent, the energy efficiency levels attained by conforming to the 1997 MNECB.

Ontario Regulation 315/11 was made under the Building Code Act to require energy efficiency for large buildings and small non-residential buildings conform to an updated Supplementary Standard SB-10. When the six-year ‘roadmap’ for energy efficiency expired on December 31, 2011-as set out by the Ontario Building Code ( OBC) and relative to the dated 1997 Model National Energy Code for Buildings ( MNECB)-a new path was laid out for the future. It can be subscribed to independently, as a part of the Standard 90.1: Energy Standard for Buildings Course Package, or Standards eLibrary.Ontario has signalled its intent to remain among the energy efficiency leaders in North America for new building construction in adopting American National Standards Institute/American Society of Heating, Refrigerating, and Air-conditioning Engineers/Illuminating Engineering Society of North America (ANSI/ASHRAE/IESNA) 90.1-2010, Energy Standard for Buildings Except Low-rise Residential Buildings. This course is targeted at design professionals and building owners, helping them successfully achieve their LEED submission objectives. Appendix G is especially useful for energy simulations connected with LEED credits and with U.S. Appendix G provides specific guidance on the rules and procedures needed to simulate building energy usage when the objective is to substantially exceed the requirements of the Standard. This course presents an overview of Standard 90.1 and then explains Appendix G, which is an informative appendix in the Standard. The 2010 version marks a major change to the Standard with a goal of saving 30% more energy than the 2004 version. Standard 90.1 has become the technical basis for meeting the energy efficiency requirements that must be achieved to obtain LEED certification for a commercial building or other facilities.
