The most energy efficient design is one that meets the needs of the users, of the processes and of asset maintenance while implementing the most efficient systems and equipments. Thanks to energy saving studies, one can clearly and precisely identify the mode of operation and investments that could lead to a reduction in energy consumption and operating costs.
Our approach to energy efficiency aims to optimize a building’s energy consumption and includes the following options :
- Applying for grant programs offered by public suppliers (Hydro-Québec, Énergir and Gazifère).
- Reducing energy consumption thanks to the validation of the electromechanical systems’ conceptual criteria (lighting levels, temperature, relative humidity, acceptable variations, etc.).
- Integrated building design in collaboration with other professionals, especially for the optimization of the building’s envelope (orientation of the building, story height, thermal resistance of the envelope, inertia, choice of materials, etc.).
- Use of systems allowing a transfer of energy, the use of low-temperature heat-transfer fluids and the transfer of energy from one area of the building to another.
- Selection of energy sources, including renewable energy sources (natural lighting, heat recovery, passive and active solar energy, photovoltaic energy, wind energy, biomass, geothermy, solid, liquid and phase change energy storage), and traditional sources, hydroelectricity, fossil sources and cogeneration (natural gas, oil).
The study of the overall building includes the study of its energy consumption (hours of operation, fresh air input, lighting, ventilation) and its energy production (boilers, water heaters, energy recovery). It also enables us to spot the necessary replacements of obsolete equipments.
