Simplicity of design and execution make a winner

The north elevation. All windows are operable for natural ventilation

In cross-section, this two storey, 1,115 sq.m office building is a simple flat roofed rectangle, the upper level being a partial mezzanine leaving double height spaces to promote stratification of warm air. In plan the building is elongated in the east-west direction, maximizing the benefits of north and south exposure for day-lighting and passive solar heating. (more…)

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…)

Rendering of the Richmond Olympic Oal. The proprietary pre-fab “woodwave” panel system was designed, fabricated and installed by Structurecraft Builders Inc., and spans between the glulam arches.

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…)

Integrated design delivers Ontario’s first LEED Platinum

The north elevation. All windows are operable for natural ventilation.

The new Restoration Services Centre is located on the Toronto Conservation Authority’s ‘Living City Campus’ in Vaughan ON, home of the newly created secretariat of the World Green Building Council. The new structure symbolizes the TCRA’s commitment to energy efficiency and excellence in environmental design, within its broader mandate of environmental restoration and conservation in the Toronto region.

Space efficiency and student ideas remake college

The gymnasium extension with reuse of an existing handicap ramp. The design maximizes space efficiency for the most minimal footprint – a basic of green building – and economized on the construction budget.

In 2003, the Collège Notre-Dame-de-Lourdes was both celebrating its 50th anniversary and facing major difficulties: its location between two highly competitive private schools, a series of problems related to poor building maintenance, bad use of space, and unattractive settings threatened its viability. In order to fulfill its mission, the college needed to attract a new clientele and increase its enrollment from 600 to 950. (more…)
