BC Energy Step Code

The BC Energy Step Code has been adopted by many Municipalities in the Lower Mainland and across BC. The BC Step Code is an optional energy efficiency regulation produced by the BC Provincial Government. Adoption of the Code by Municipalities is decided by the individual Municipality. The BC Step Code website (BC Energy Step Code) provides information on the Code and lists Municipalities that have adopted it.

The BC Step Code changes the way buildings are designed and constructed. Exterior wall, roof, window and door assemblies require upgrades. The required upgrades are project specific but generally include higher effective thermal resistance and controlled air leakage.

APEGBC Innovation Article – HPO Reconstruction Rules

Working with Richard Linzey, Manager, Heritage Programs and Services, Heritage Branch, Ministry of Forests, Lands and Natural Resource Operations, Jeff Renwick P.Eng. principal of bamtec has co-authored an article in the APEGBC Innovation magazine regarding the latest amendments to the Homeowner Protection Act, and policy change with respect to “Substantial reconstruction” renovation or conversion projects.

The amendments allow certain architectural components of designated heritage buildings that do not strictly conform to the requirements of current building code regulations to be exempt from the Homeowner Protection Act warranty requirements, on commercial to residential conversions. In addition, the Homeowner Protection Office has issued a policy change clarifying the threshold at which renovation or reconstruction of designated heritage buildings triggers the Homeowner Protection warranty requirements.

In doing so, the changes recognize the importance of retaining heritage fabric within our communities.

The article was published in the Innovation magazine the week of July 25, 2011 and is available online thereafter @ .
