Changes to the BC Building Code became law on December 19, 2014, making new homes and small buildings more energy efficient.
The goal is energy conservation and greenhouse gas reduction, and the changes to the Code, Part 9 Buildings, set minimum standards for:
energy efficiency: for homes and small buildings there are new minimum standards for insulation performance, heating and cooling systems, hot water tanks, and doors, windows and skylights. Energy efficiency standards for insulation in walls are extended to every part of a building, including framing, sheathing and cladding;
ventilation: requirements include improved air flow to reduce the likelihood of mould and mildew; and
radon rough-ins: builders must now rough-in radon vent pipes that vent outside, instead of capping pipes.
Child care facilities are also addressed. The new code clarifies that buildings containing child care facilities may be classified as Assembly Occupancy (A-2). Child care facilities can occupy small wood-frame buildings if certain fire safety requirements are met.
