Team Montreals mission for this competition was to produce a house in which the principal components are optimally balanced and highly energy-efficient. The project follows an architectural program in order to promote eco-efficient choices, preserve non-renewable natural resources and recycle residual materials. The vision of an ecologically viable and sound construction guides Team Montreal in all their structural, architectural, and technological decisions. Team Montreal followed nine guidelines in the design and execution of Lumen|Essence.

All the while maintaining fluidity between the two realms. The 580 square foot open plan encourages a synergistic organization of working, socializing, and resting in the home. The green South façade wall and North side green roof create a natural cleansing system and allow for rain water to be collected and stored for periods of drought. The single-surface photovoltaic and thermal solar array and yellow-clad mechanical core are bold architectural gestures intended to highlight the importance of integrating solar energy in the worlds quest towards social and environmental sustainability.

It offers precision, strength, and architectural flexibility. It (the structure) is recyclable, reusable, and eliminates waste not only in the construction phase but also in case of further renovation or relocation. The design of the home takes advantage of the unique structural properties of steel, the principal structural material, allowing it to span longer distances yielding greater flexibility in design and construction. Spatial constraints such as intermediary columns and bearing walls are eliminated. This offers endless possibilities for an open plan concept, providing occupants with a large home feel. 02 Transverse Section BB

Precedent Analysis arc 572 UT Solar Decathlon 2009 Lumen|Essence Team Montreal | 2007 architecture materials comfort zone getting around engineering appliances energy balance communications lighting hot water market viability ARCHITECTURE I INTERIOR I TECHNOLOGY I SOCIETY 02 Insulated Panel Installation Insulation: Lumen|Essence is designed with an rigid insulation composed of soy beans and recycled plastic sprayed over the structure before the exterior siding panels are installed, an ideal composition to ensure a complete and continuous thermal blanket. This sandwich keeps the home cool in the summer and warm in the winter as well as preventing moisture permeation and thermal shorts. The use of Low-E, argon gas filled, triple glazed windows minimizes heat exchange between the interior and exterior. Improving the efficacy of the glazing is the automated shading system which ensures efficiency and balance as the heat is kept inside during colder weather. 01 Wall Section

The Green wall on the South face assists in collecting and dispersing the intense solar radiation experienced in the summer months. In the winter, the same mass acts to store that same radiation. The Green wall acts in much the same manner, with additional benefit in collecting storm water and allowing it to disperse gradually, rather than quickly discharge and facilitate erosion. 01 Living Wall Section 02 Green Wall Assembly

The automation system can either alert the users as to the optimal time to complete the task, or if desired, execute the basic daily tasks like washing, drying, and cooking. Bath time is not currently automated. The Diva 12amp cooking surface provides low amp usage and an additional safety measure, since the heat is generated when metal is placed on the surface. The plumbing fixtures are also eco-friendly, as exhibited in the low flow shower head and dual flush toilet.

Precedent Analysis arc 572 UT Solar Decathlon 2009 Lumen|Essence Team Montreal | 2007 architecture materials comfort zone getting around engineering appliances energy balance communications lighting hot water market viability ARCHITECTURE I INTERIOR I TECHNOLOGY I SOCIETY Energy Balance: Lumen|Essence generates electricity by forty 205W Sanyo PV solar panels. The system can generate 8.2kW, adequate for the two occupants. The 30˚ slope to the roof, optimal for Montreals climate, allows the suns rays to enter perpendicularly to the PV cells. The slope is also a common slope, which eases construction cost and labor unfamiliarity. The home, as a result of the dust and rain, did poorly in this area of the competition and was not able to generate enough power for the length of the competition. 01 PV Cleaning 02 DC Battery Bank03 Power Generation + Consumption 03 Roof Section with PV Panels
