Key Messages from the United Nations Environmental Program“It is estimated that at present, buildings contribute as much as one third of total global greenhouse gas emissions…

Decision-makers…need to make the mitigation of greenhouse gas emissions from buildings the cornerstone of every national climate change strategy.”

The building sector has the most potential for delivering significant and cost-effective GHG emission reductions.

Proven policies, technologies and knowledge already exist to deliver deep cuts in building related GHG emissions.

Significant co-benefits including green jobs and increased employment will be created by policies that encourage energy efficient and low-emission building activity.

135

Countries will not meet emission reduction targets without supporting energy efficiency gains in the building sector.

The building industry is committed to action and in many countries is already playing a leading role.

Failure to encourage energy-efficiency and low-carbon when building new or retrofitting will lock countries into the disadvantages of poor performing buildings for decades.

In the City of North Vancouver, buildings contribute to approximately 50% of GHG emissions and 70% of energy use.

Our Official Community Plan Targets:

15% reduction below 2007 levels by 2020 (approximately 36,500 tonnes CO2e of reductions)

To pursue increasingly aggressive energy standards for new and existing buildings over time… with a goal of 20% better than theBC Building Code

A Quick guide to Building Energy Performance standards

• Developed by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) for industrial, commercial and institutional buildings that exceed 1,000 square metres, as well as residential buildings over four storeys.

• Focuses on energy savings from more efficient operations of mechanical systems in the buildings.

• Updated every three years, the most recent versions include 2004, 2007 and 2010.

• Jointly-produced by the Canadian Commission on Building and Fire Codes in partnership with the provinces, territories, the National Research Council of Canada, and Natural Resources Canada.

• Focuses on energy savings from more efficient building design and operations.

• First edition was developed in 2011. The previous Canadian National Code was the Model National Energy Code of Buildings (MNECB) 1997.

Energy Standards trends in BC

yes! The United states is anticipating the adoption of ASHRAE 90.1-2010 by all States by October 2013. The Province of Ontario has also offered industry options to either:1) exceed energy efficiency level of MNECB-1997 by 25%, or2) exceed energy efficiency of ASHRAE 90.1-2010 reference building by 5%; or3) meet prescribed modifications of ASHRAE 90.1-2010 as set out by its

provincial building code.

Have any other North American

jurisdictions adopted higher energy

standards?

No! The City’s Official Community Plan stipulates maximum density limits for each lot in the City. These provisions for meeting higher energy standards will not exceed the OCP’s limits. Any development applications that contemplate density bonuses for “environmental considerations” beyond the densities laid out in Schedule ‘A’ of the OCP will continue to be considered by Council on a discretionary basis. This additional density factor is laid out in Section 5.12.5 of the OCP and does not relate to the Energy Efficient Buildings Program.

Can a building receive density beyond the OCP limit through this Energy Efficient Buildings Program?

As green buildings technology and energy standards continue to evolve, higher energy- efficiency is becoming more achievable and cost-effective. ASHRAE 90.1-2010 and NECB-2011 are two such standards being considered by the Province of BC and the City of Vancouver as the next referenced energy standards in their building codes.

The City has the opportunity to raise our energy standard requirements in the Density Bonusing Program by providing the industry with a choice to meet ASHRAE 90.1-2010 or NECB-2011. The new energy standards will further contribute to the City’s commitment to sustainability and to meeting community-wide greenhouse gas reduction targets.
