BC Energy Efficiency Act
New Regulations for Windows and Doors
New regulations for the manufacture of windows, doors and skylights in B.C. took effect on June 1. Brought in under the BC Energy Efficiency Act, the regulations are part of a broad provincial strategy to reduce energy consumption in buildings. While designated buildings are exempt from the regulations, other heritage buildings are not.
Existing windows and doors in heritage buildings may be refurbished without reference to the regulations, but replacement windows and doors will have to conform to the new rules. This includes storm windows.
The problem for manufacturers of replacement windows and doors for heritage buildings is that the new regulations will place significant constraints on their options. Replacement of inappropriate windows and doors is common in the rehabilitation of historic properties. Under the new regulations, the options will be severely constrained.
Manufacturers of specialty wood windows and doors, and members of the heritage community, only became aware of this issue shortly before the new regulations came into effect. A couple of meetings with the provincial Heritage Branch and the Alternative Energy Policy Branch have already taken place. Key issues include a proposal to extend the exemption to include register as well as designated heritage status.
