Great Gulf Active House

Big builder pushes the boundaries of green residential development

Great Gulf, one of the country’s largest home builders, is simultaneously concerned with being an innovative, forward-thinking company, and a competitive builder in the residential market. This project in Thorold, Ontario was a leap of faith in a market that has not to date shown much interest in sustainability. Using the existing local design guidelines of a traditional gabled roof design and adapting them for the Active House yielded a multi-functional design that was the basis for an open plan, an abundance of interior daylight, and a house of superior environmental performance.

Maison du Developpement Durable

Tuesday, December 24th, 2013

First building in Quebec to achieve LEED® Platinum NC status, the Maison du développement durable [MDD], is located in the heart of the Quartier des spectacles [Montreal’s Entertainment District]: a lively area with a rich architectural tradition. The project had to deal with the challenges inherent in a downtown site, such as contaminated soil and restricted access, together with the challenges of LEED Platinum construction.

Authored by the design team at Menkès Shooner Dagenais LeTourneux Architectes, Montreal.

JURY COMMENT - A simple and elegant renovation/addition that combines beautiful design with impressive energy performance. The straightforward approaches taken to daylight and natural ventilation are indicative of how the many green strategies are deftly interwoven into the architecture. Located in a neighbourhood of modest, late 19th century worker housing, this project demonstrates the potential for this typology to provide a sustainable, ground oriented and cost effective alternative to the high-rise condominium.

J URY COMMENT - A project notable for its modesty, but which at the same time is warm and inviting in its materiality and use of natural daylight. The interiors are beautiful, the surrounding landscaping makes for an appealing playspace, and the performance numbers for energy and water are particularly impressive. The directness of the design approach and the simplicity of the environmental systems offers a level of confidence that net zero performance can be maintained over time. All and all an engaging environment in which future generations can learn about sustainability.

Heritage home morphs to open modern

by Jim Taggart

The renewal of this 125-year old small Victorian home presented a typical challenge in Toronto – altering and updating the existing residential urban fabric while preserving the historic character of heritage neighbourhoods.

Low-tech design makes a sustainable home.

This project began with a suburban infill site in an established downtown west end neighbourhood of Moncton characterized by generic production houses. The intention was to create a custom-designed family home that responded to the opportunities of the site and neighbourhood context, while using “low-tech’ methods to maximize the benefits of passive solar design, natural lighting and natural ventilation.


Model green design squeezes most from tight city budget

Niagara Regional Headquarters

The new building creates an urban street presence at a suburban intersection.

The tight budget and schedule requirements of a Design Build contract, combined with the sustainable agenda of a LEED® municipal client set this project apart from others of similar scope and scale. The four-storey office building is an extension to the existing Thorold City Hall, and consolidates operational services for the Niagara Region. (more…)

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.
Jeong-sik Jeong and Gilbert Larocque

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…)

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…)

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…)
