Is B.C.’s Energy Step Code a blueprint for Canada?

Innovative building standard off
to a promising start

In 2017, British Columbia introduced what might be North America’s most innovative beyond-code standard for energy efficiency. The B.C. Energy Step Code is an opt-in regulation that enables local governments to pursue improved levels of performance for new homes and buildings — creating healthier and more comfortable spaces that are more affordable to heat. It’s a promising experiment that could chart a path for the rest of Canada.

Choosing the right windows for your house

Thursday, October 23rd, 2014

A brief guide:

Windows are essential to our houses. They give us natural light, a way to ventilate the home without depending on mechanical systems, a means of emergency exit, and offer an alternative way to heat the house free of charge through passive heating.

Building Envelope Design

The basics start with environmental loads

Building envelopes must be designed to perform under all weather conditions. The BC Cancer Agency Research Centre in Vancouver by IBI Group ans Henriquez Architects.

Modern building systems consist of structural, service and envelope components that can be respectively compared to the bones, organs and skin of the human body. The skin protects the body from harmful exterior environments and maintains comfortable body conditions. In the same manner, the building envelope aims to regulate indoor environmental conditions for human use or occupancy. (more…)

Understanding Sound Masking

Saturday, July 26th, 2008

An installed sound masking system is almost indiscernible to occupants.

Just as with light, temperature and humidity, there is a comfort zone for the volume of sound in an occupied space. It is determined by the noise floor, or the level of continuous background sound. If the noise floor is too high, the environment is irritating and tiring. If it is too low, other occupants’ conversations are easily overheard and noises cause distractions.
Acoustically, green buildings present additional challenges because the strategies that help with daylighting, natural ventilation and temperature regulation also tend to lower their acoustic performance. (more…)

The increasing concern for energy efficiency and other green building strategies, as codified in the LEED Rating System [as well as other rating systems], considers many aspects of indoor environmental quality but does not explicitly provide credits for good acoustical design. (more…)

Design flexibility, energy efficiency and healthy environments

by Bill Reynolds

.

A sustainable approach to building design brings with it demands for flexibility, energy efficiency and healthy work environments. Interior spaces need to respond rapidly and cost effectively to organizational and technological changes. Meanwhile, steadily increasing energy costs require building systems that operate with improved efficiencies while ensuring a healthy, comfortable environment for building occupants. (more…)
