Greening the high-rise office
Tuesday, May 4th, 2010Pointers 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.

Living roof Case Study
Thursday, March 11th, 2010Vancouver 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.

Controls for Building HVAC & Lighting
Monday, January 11th, 2010The basics on the all-important “nerve centre”
Controls are the brains of a building and are responsible for the performance of the mechanical and lighting systems. Because these systems are the primary consumers of building energy, the controls must be well designed, commissioned and maintained if energy performance is to meet design expectations.

Design for disassembly
Tuesday, October 27th, 2009Early 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…)

Considerations to stay with conventional installation methods of roofing in order to keep initial cost low can no longer stand against improved installation methods and new products that provide long term returns.
Not surprisingly, higher initial investment in denser insulation, membrane thickness, good drainage and reflectivity brings the greatest return on investment. Such measures deliver longevity that lowers the life cycle cost of roofing by decreasing material sourcing, manufacturing energy cost and transportation. And a decrease in repeated installation and demolition reduces the need for raw materials, transportation and landfill space. The added benefits of energy savings are a bonus.
Duro-Last Roofing Inc., considers sustainability in roofing as requiring all of the Five E’s: Energy, Environment, Endurance, Economics, and Engineering. The time for short cuts and ‘it’s good enough’ attitudes may be finally outdated. (more…)

When LEED was first launched about 10 years ago, it filled a huge void in the marketplace because it provided both an effective definition of a green building, and a means to measure green building performance in a consistent way.

One of the million or so iconic Veterans’ Homes, the Now House is upgraded to a net-zero energy level
by Lorrane Gautier and Don Fugler
The Now House is one of the 15 net-zero energy healthy housing projects selected from across Canada to be part of the Canada Mortage and Housing Corporation’s EQuilibriumTM Sustainable Housing Demonstration Initiative. The project comprised the renovation and retrofit of a 60 year old house, one of a million similar homes built across the country during and after World War II, and is the only EQuilibrium™ project focused on the renovation and retrofit market.

Commercial glazing systems
Tuesday, March 10th, 2009A summary of recent advances
Glazing considerations such as window area, elevation and orientation, thermal performance and solar shading to optimize natural daylighting and passive solar heat gain are very important to the envelope performance and energy consumption of buildings [1].

by Hugh Perry
Many of Canada’s commercial buildings were built over 40 years ago when there were few, if any, worries about energy performance and environmental responsibility. In an era of cheap and abundant energy, heating and cooling loads were of little concern; buildings were often clad entirely in glass with no differentiation between facades having different orientations.
