Regenerative buildings
Regenerative buildings and living buildings are a new paradigm in the field of sustainable architecture, particularly relevant to Alberta, Canada, given its unique climate and environmental conditions. These buildings go beyond the traditional concept of sustainability, which often focuses on minimizing harm, to actively improve the environment. They are designed to be self-sufficient, generating more energy than they consume, capturing and treating all water on-site, and using resources efficiently to create a positive impact on the environment.
In Alberta, the adoption of regenerative and living buildings is gaining momentum. The province’s diverse climate, ranging from cold winters to warm summers, presents an opportunity for these buildings to utilize renewable energy sources such as solar and wind power. For instance, the Mosaic Centre for Conscious Community and Commerce in Edmonton is Alberta’s first net-zero commercial building, generating more energy than it consumes annually. It exemplifies the principles of regenerative design, featuring solar panels, geothermal heating and cooling, and a tight building envelope for energy efficiency.
Moreover, the Living Building Challenge, a green building certification program, has inspired several projects in Alberta. This program sets rigorous standards for sustainable design, including net-positive energy, water, and waste. The University of Calgary’s Child Development Centre, for instance, is pursuing this certification. It features a green roof, rainwater harvesting, and natural ventilation, embodying the principles of living buildings. As Alberta continues to embrace these innovative design approaches, it contributes to a more sustainable and resilient future.
Decarbonization.
Decarbonizing existing buildings is a crucial aspect of achieving sustainability goals, particularly in regions like Alberta, Canada, where the built environment contributes significantly to greenhouse gas emissions. Decarbonization involves reducing the carbon footprint of buildings through energy efficiency improvements and the use of renewable energy sources. This can be achieved through various strategies such as retrofitting older buildings with energy-efficient technologies, using low-carbon construction materials, and integrating renewable energy systems.
Retrofitting is a key strategy in decarbonizing existing buildings. It involves upgrading the building’s systems and infrastructure to improve energy efficiency. This could include enhancing insulation, installing energy-efficient lighting and appliances, and improving heating, ventilation, and air conditioning (HVAC) systems. On the other hand, integrating renewable energy systems, such as solar panels or wind turbines, can reduce the reliance on fossil fuels for electricity and heating. In Alberta, initiatives like the Energy Efficiency Alberta’s Home Improvement Rebates program have been introduced to encourage homeowners to make energy-efficient retrofits. As these strategies are increasingly adopted, the decarbonization of existing buildings will play a pivotal role in mitigating climate change and moving towards a more sustainable future.
