What we build has an impact now, and in the future, when it comes to building sustainable communities. More than ever, the built environment needs to demonstrate the 3 pillars of sustainability, which are economic, social, and environmental. Well planned and designed communities and buildings need to balance the role of affordability, livability and well-being.
The residential construction industry understands the importance of environmental sustainability and is taking steps to reduce the environmental impact of the built environment.
Builders are increasingly using materials that have a lower environmental impact. Examples:
More choices in sustainable materials are becoming increasingly available, like Biofibers, Carbon Neutral Silicones, Cementitious materials with the addition of fly ash and hempcrete just to name a few. By using sustainable building materials in homes, we can reduce our environmental impact, create more energy-efficient and resilient buildings, and support a more sustainable future.
Builders are incorporating energy-efficient designs which takes a whole house systems approach that considers all the variables, details and interactions that affect energy use in the home. Incorporating the latest technology in insulation and air sealing, lighting, day lighting (natural light), space heating and cooling, water heating, windows and doors. These homes can be rated and labeled by a Certified Energy Auditor that variefies the homes energy performance. The whole whom approach can maximize the reduction in energy consumption and carbon emissions.
Builders are incorporating water-conserving fixtures like low flow toilets, faucets and shower heads that reduce water consumption. ENERGY STAR appliances are certified to save water as well as energy. A standard certified dishwasher can save an average of 3,870 gallons of water and a certified clothes washer uses 33% less water.[iii]. In addition, efficient piping eliminates potential conflicts with structural and mechanical elements in the home.
Builders are increasingly paying attention to construction waste and recycling options, such as concrete and wood, to reduce landfill waste and conserve natural resources. While Regina has limited option in this area, those choices are growing.
Builders are constructing and renovating net-zero energy homes that produce as much energy as they consume, often through the use of renewable energy sources. The Canadian Home Builders Association (CHBA) has developed the Net Zero Energy (NZE), Net Zero Energy Ready (NZER) and Net Zero Renovation programs. These programs include training in building science and labeling of new homes and deep retrofits through a qualified service organization. These builders and renovators are trained to ensure that their NZE projects meet strict environmental standards. The Regina & Region Home Builders Association has facilitated 28 individuals to be experts in NZE Building.
Builders and Community Developers are increasingly incorporating sustainable landscaping practices, such as:
By implementing sustainable landscaping practices in new neighborhoods, we can create healthier, more resilient communities that benefit both people and the environment.
These are just a few examples of the actions that the residential construction industry is taking to promote environmental sustainability. As awareness grows and technology advances, the industry will continue to make progress in this area.
