Project Profile: Steel decking and steel roof in an energy-efficient home

Project: ECOTERRA™ House
Location: Eastman, Quebec

The company built the factory-built, pre-engineered home in Eastman, Quebec and demonstrated it to the public for two years before selling it to a private owner. 

The two-storey home has a footprint of 82.5 m2 (888 sq. ft.) and 141 m2 (1,517 sq. ft.) of interior space. There is a living room, dining room, kitchen, bathroom and laundry on the first floor and two bedrooms, an office and a bathroom on the second floor. 


Les Maisons Alouette chose pre-painted galvanized steel standing seam roof, coloured QC6068 Black, of which 57.2 m2 (616.7 sq. ft.) is south-facing, to comply with a subdivision covenant. That requirement, however, was well-suited for the solar array, manufactured by Michigan, USA-based UniSolar: The three kilowatt, thin-film photovoltaic array is laminated to the south-facing roof and is almost invisible. The result is a nearly seamless integration of the solar panels with the house. 


Heat from a cavity beneath the metal roof is recovered for the clothes dryer, to help heat the hot water and to passively heat the basement floor space through a ventilated slab. To heat the 4m by 11m (13’ by 36’) room, the air in the roof cavity, which reaches 75ºC (167ºF) in the summer and 55ºC to 60ºC (131ºF to 140ºF) in the winter, is blown through Canam’s P2436 profile 0.7mm (.0275”) galvanized steel decking in the floor. 


First, insulation, polyethylene sheets, polystyrene insulation and expanded metal grating was laid down, then the decking was laid down and covered with 125mm (5”) of concrete. The cold formed steel decking acts as a hollow core for the heated air to blow through. The grating creates turbulence to give the air better contact with the steel decking, another innovative use of cold formed steel in residential construction. 


The solar array can generate up to 3,420 kilowatt hours (3,420,000 watt-hours) a year. The array and the other energy efficient features of the house, which requires only 17% of the energy of the average Canadian home, result in a net energy consumption of nearly zero.

SFIA gives Webinar on the Risks of Wood Framing/Code Changes



The Steel Framing Industry Association is a USA-based sister organization to the CSSBI. As we have seen similar code changes for combustible materials in Canada, this webinar touched on many of the same concerns the steel and concrete industries have expressed in Canada.

This last Thursday the SFIA Professional Development series featured an online presentation by Chief Steve Lohr, currently the Fire Chief of Hagerstown, MD and who recently retired as Chief of the Montgomery County, MD Fire and Rescue Services.  Steve has recent, first-hand experience fighting a mid-rise wood-frame fire and he’s agreed to testify before a committee of the Maryland State Legislature about the dangers these structures represent.

Watch the video to see a clip reporting on the 2014 fire that destroyed the Upper Gables apartments in Rockville, MD.

Cas d'étude: Programme d’amélioration des installations sportives – l’acier, un choix évident

Projet: George Brown College
Toronto, ON

Le gymnase du collège George Brown de Toronto avait désespérément besoin d’être modernisé. Construit initialement dans les années 1970, le gymnase devait être rénové. « Tout l’équipement se trouvait dans un petit espace dépourvu de lumière naturelle. Seuls les rats de gymnase s’en servaient », selon M. YewThong Leong, architecte principal de SSG Architecture. « On nous a demandé d’ajouter une annexe au gymnase. Les besoins du collège en matière d’activités récréatives ont changé. Ils voulaient notamment un studio pour le yoga. »

Une charpente en acier léger a été choisie en raison de ses propriétés de construction non combustibles, de son poids léger et de sa capacité d’intégration à la nouvelle structure. L’acier permet de personnaliser facilement l’ensemble de la charpente et des éléments afin de s’harmoniser avec les écarts d’espacement de la structure historique.

L’ajout d’une annexe moderne à un bâtiment historique a constitué l’un des défis de ce projet. « L’annexe d’un immeuble historique se doit d’être construite de telle sorte qu’il soit possible de la retirer, et l’acier est parfait pour ce faire », indique M. Leong. « Le nouvel immeuble est entièrement construit en acier. » 

Les impératifs du calendrier de construction ont imposé l’érection de la superstructure pendant l’automne et la saison hivernale. Du fait de l’emploi d’une méthode de construction à sec, l’installation hivernale représentait une solution sûre. La préfabrication des composants a permis de poursuivre en toute sécurité les travaux de construction, tandis que le bâtiment actuel était utilisé par le personnel et les étudiants.

Il ajoute également que l’acier a été choisi pour sa solidité et son poids relativement léger. « Tout l’acier est découvert. Nous voulions que le design présente un certain degré d’honnêteté. L’acier a été peinturé de couleur blanche. Cela donne un effet de halo avec la lumière externe, le bâtiment semble tout simplement rayonner. » 


La construction de l’annexe a pris fin l’an dernier. Il s’agissait de la troisième et dernière phase du plan d’amélioration des installations sportives. « L’acier n’a pas un aspect lourd comme le béton. Le recours à l’acier donne un effet de légèreté à l’ensemble », selon M. Leong. « L’annexe est superbe. Elle offre une vue incroyable et profite de beaucoup de lumière naturelle. Ce bâtiment a été très bien reçu. » 

L’ajout offre tout l’espace nécessaire pour élargir les programmes existants de musculation et d’activités cardiovasculaires qui ont actuellement cours au même étage dans un endroit dépourvu de fenêtre du gymnase des années 1970. Une fois les installations existantes déplacées, l’espace a été rénové pour en faire une nouvelle salle de vélo et des studios pour les classes d’exercice.

Le nouvel espace est beaucoup plus convivial et cela incite beaucoup d’étudiants à s’entraîner au collège. « La faculté a fait quelques changements. Finalement, l’annexe sert de salle de musculation et compte de nombreux appareils cardiovasculaires. Le studio de yoga figurait mieux dans le bâtiment initial » explique M. Leong. « L’annexe attire une autre clientèle. C’est une réussite et nous en sommes bien heureux. »

Project Profile: Athletics Facility Enhancement Program – Steel was the obvious choice

Project: George Brown College
Location: Toronto, ON

The gymnasium at George Brown College in Toronto was in desperate need of an upgrade. Originally built in the 1970s, the gym was due for an overhaul. “All the exercise equipment was stuck in the same small space with no natural light. The only people who used it were gym rats,” says Yew-Thong Leong, Principal Architect with SSG Architecture. “We were asked to put an addition adjacent to the gym. The college’s recreational needs had changed. They wanted a yoga studio, among other things.”

Light steel framing was selected for its noncombustible construction properties, lightweight and its ability to integrating with the new structure. Steel allowed for easily customizing all the members and elements to align with the in congruencies of the historic structure’s differential grid spacing.

One of the challenges the project posed was the need to add a modern addition to a historical building. “When you’re building an addition to a historical building, you have to do it in such a way that it can be removed, and steel allows for that,” Leong says. “The new building is entirely made of steel.”

The construction schedule dictated that the super structure would be erected during the fall and through the winter months. A dry construction method made winter installation a safe possibility. Prefabrication of components allowed for construction to continue safely while the existing building is occupied with staff and students.

He adds that steel was also chosen for its strength and relatively light weight. “We left all the steel exposed. We wanted there to be a level of honesty about the design. We painted the steel pure white. It has a halo effect from the amount of light coming in – it simply glows.”


Construction of the addition was completed a year ago. This latest addition was the third and final phase of the Athletics Facility Enhancement Plan. “Steel doesn’t look as heavy as concrete. The use of steel added a lighter feel to the space,” says Leong. “The addition is amazing. It has incredible views and lots of natural light. It’s been very well received.”

The addition provides space for the purpose of expanding the programs for the existing weight lifting and cardio facility which is currently housed in a window-less space within a 1970s gymnasium addition on the same floor. Once the existing facilities were vacated, they were renovated into a new cycle room and studios for movement classes.

The new space is a lot friendlier, and it’s encouraged more students to work out at the college, he says. “The faculty bumped a few things around. In the end, the addition became the weight-training room, with a lot of cardio machines. The yoga studio was better suited to the original building,” Leong explains. “The addition has brought out a different population. It’s quite well done, and we’re very happy about it.”
