Strategies for Wireless Systems

Minimizing the energy consumption for lighting can only be achieved when the lighting is controlled in an efficient manner. The better this goal is achieved, the greater the energy savings.

Pointers from a front-line practitioner

Throughout Canada, as in the rest of the developed world, employers are confronting the looming demographic crisis — the retirement of vast numbers of baby boomers from the workforce — and projected acute shortage of younger skilled workers to replace them. The competition to attract and retain these workers has begun in earnest, and there is a growing consensus in the marketplace that offering a high quality work environment is an essential key to success. The result is a revolution in commercial office building design, the first since the 1960s.

Vancouver Convention Centre | Simple outward appearance belies underlying complexity of Canada’s largest green roof

The Vancouver Convention Centre Expansion Project [VCCEP] which opened in April 2009 occupies a prominent site on the city’s Coal Harbour waterfront, with sweeping views west to Stanley Park and north and east to the Coast Mountains. Designed by Seattle-based LMN Architects, in conjunction with Vancouver’s Musson Cattel Mackey Partnership and DA Architects & Planners, the 100 000sq.m [1.1 million sf] facility was conceived as a model of sustainable design for large-scale civic buildings.

Early planning means an economic afterlife for buildings

by Vince Catalli

The traditional model for the design, construction, operation, decommissioning, demolition and disposal of a building is a linear, sequence in which new materials, products and building systems are created at the beginning of a project and discarded at the end. (more…)

New rating systems will change our ways

Green roof of the Burnside Gorge community Centre controls stormwater runoff as part of a landscaping strategy that contributes points to LEED Gold certification.

We think of the landscape as green by default. In reality, it is challenging to achieve this goal in urban areas where requirements are imposed by market expectations, municipal requirements, and a range of other factors.
At the same time, green building rating systems are beginning to demonstrate their power to transform both the market and the regulatory context, and are offering opportunities for landscape architects, engineers, and other designers to apply a variety of new approaches to site development.

for high performance buildings

The Earth Rangers Centre uses earth tubes and a double foundation wall. The energy recovery in winter and summer is sufficient to temper the air about 5º C on average and up to 10º C on cold days.

It has become increasingly common to provide heat recovery on ventilation systems in buildings. In fact, it is difficult to achieve the minimum energy performance requirements for a LEED or other high performance building without it. (more…)

Product choices and considerations for energy savings

Thermafiber’s Mineral Wool Insulation contains over 80% recycled content and helps projects qualify for LEED Green Building Credits.

Insulation is only one component of many in the building envelope - but arguably the most critical one in determining energy savings and interior thermal comfort. Every aspect of the envelope design must be considered including the air tightness and the positioning of windows within the thickness of the walls. (more…)

The green roof of Electronic Arts, Phase II. Musson Cattell Mackey Partnership, Vancouver.

The use of green roofs for aesthetic and recreational purposes can be traced back to the Hanging Gardens of Babylon which were built in the 7th century BC as a diversion for the aristocracy. Later, more practical applications emerged in Scandinavia and North America where sod roofs, laid on a waterproof layer of bark, were used to insulate indigenous dwellings against the extreme cold.
