Larkin Architect Ltd. More than just extraordinary, colourful and lightfilled space, the design foe St. Gabriel,s reflects the unique eco-theology of the Catholic Passionist Community in Toronto . For them, the most important challenge of our time is to establish a mutually-enhancing, human-earth relationship. Like medieval cathedral of the past, the goal of their new church is to help communicate this message to the public. In response to the client’s ecological mandate,leading edge sustainable strategies were integrated into the design. The entire south façade of the worship space at St. Gabriel’s is glazed to passively harness the winter sun’s energy and extend the worship area visually into an extensively planted garden beyond. A large iconic canopy provides shade in summer. The remaining three walls of exposed architectural concrete serve as a constantly changing canvas for the dynamic play of coloured light that is filtered through the coloured glass panels of the continuous perimeter skylight and affected by seasonal influences on the sun’s intensity and inclination, together with daily weather conditions. The unprecedented investment in underground parking reduces the building’s impact on the urban heat island effect and contributes to wildlife habitat. The extensive green roof garden, located over the underground parking, with its drought-tolerant plants and drip-irrigation system, reduces potable water use by 78%. Waterless urinals, dual flush toilets, and solar-powered low-flow faucets provide an additional 47% water reduction. To reduce their impact on global warming and resource use, the client has purchased and ultra low-emissions hybrid vehicle. St. Gabriel’s is also located within easy walking distance of two subway stations encouraging parishioners to leave their cars at home and arrive via public transit."While reducing energy costs was one of the reasons for building a 'green' church, says Fr. Paul Cusack, C.P., current Pastor at St. Gabriel's, "Our primary motivation was to establish a link between the sacredness of the gathered community of Faith and the sacredness of the Earth." Thus it has passive solar heating, natural daylighting, heat recovery wheel, a living wall and rainwater collection. Melbourne,

SUSTAINABLE FEATURES St .Gabriel’s achieves a 50% reduction in energy use and purchases their electrical power from a renewable energy supplier. The building incorporates many energy-conserving features:
Almost all interior spaces (94%) enjoy a view to the outdoors and abundant natural lighting (89%). This design results in a healthy and beautiful indoor environment and reduces energy use by reducing the need for the artificial lighting.A “living wall” of tropical plants acts to purify and condition to providing a spectacular indoor natural feature. Material Reuse Over 10% construction materials were salvaged from the original church and re-used: pews, stained glass windows, mosaics, and marble. A total of 15% of construction materials have high recycled contend, most notably structural steel, rebar, concrete and drywall. Another notable achievement is that 30% of construction materials are locally produced. A construction waste management program diverted over 50% of construction materials from landfill. St. Gabriel’s has an active recycling program and environmentally friendly maintenance regimen. Innovation in design As part of their ongoing commitment to educating others, the church has installed an interactive computer kiosk to explain the building’s sustainable design features. This kiosk is augmented by an extensive signage program both inside and outside of the building. Brochures, online essays, frequent tours, and public presentations round of the project’s commitment to a greener Toronto . |
