The Power of Integrative Passive Design Strategies in Buildings
Passive design strategies can make occupants feel 10°C to 20°C cooler, reducing or eliminating the need for mechanical cooling, while increasing resilience and reducing energy-supply strains
Passive design strategies in buildings have gained significant attention in recent years as the need for sustainable and energy-efficient buildings continues to grow. Passive design refers to the use of natural processes and design elements to regulate a building’s temperature and lighting, rather than relying on mechanical systems. Integrative passive building design, in particular, involves a holistic approach to designing a building that prioritizes energy efficiency and sustainability from the start.
One of the most significant advantages of passive building strategies is that they can make occupants feel cooler, reducing or even eliminating the need for mechanical cooling systems. This not only saves energy but also increases resilience in the face of power outages or supply chain disruptions. In fact, studies have shown that passive design strategies can make occupants feel 10°C to 20°C cooler, which can have a significant impact on energy consumption and overall building performance.
Integrative design of high-performance buildings can also reduce first costs by “tunnelling through the cost barrier.” By prioritizing energy efficiency and sustainability from the start, designers can identify cost-effective solutions that might not have been apparent if they were designing a building without these priorities in mind. This can lead to lower operating costs over the life of the building, making it a more attractive investment for building owners and operators.
Indigenous techniques and materials also provide a pathway for beneficiary-led and informal housing sectors. By drawing on local knowledge and materials, designers can create buildings that are better adapted to the local climate and culture. This can also help to support local economies and communities, creating a more sustainable and resilient built environment.
However, for passive building strategies to be widely adopted, the professional sector needs a knowledge base of case studies, costs, and benefits of passive, integrative design. Designers and builders also need tools and training to shift towards performance-based design, which focuses on creating buildings that meet specific performance metrics, rather than just meeting minimum code requirements.
The beneficiary-led sector also needs distinct technology, workforce, and market development efforts. This includes developing new technologies that are affordable and accessible to communities, training a local workforce to build and maintain these buildings, and creating new markets for sustainable and energy-efficient buildings.
In conclusion, passive building strategies, particularly integrative design, offer a promising pathway to creating more sustainable and energy-efficient buildings. However, achieving widespread adoption will require collaboration and innovation across the design, construction, and policy sectors. By prioritizing energy efficiency and sustainability from the start, we can create buildings that not only save energy but also enhance resilience, support local communities, and create a more sustainable and equitable built environment.
