Passive House Design
Detailed overview of innovation with sample startups and prominent university research
What it is
Passive House design is a rigorous building standard that focuses on achieving ultra-low energy consumption in buildings. It emphasizes a holistic approach to building design and construction, utilizing passive strategies to minimize heating and cooling demands and create comfortable and healthy indoor environments.
Impact on climate action
Passive House Design in Energy-Efficient Buildings revolutionizes climate action by drastically reducing energy consumption for heating and cooling. By optimizing insulation, airtightness, and ventilation, these designs minimize reliance on fossil fuels, lower carbon emissions, and pave the way for sustainable, energy-efficient buildings, mitigating climate change impacts.
Underlying
Technology
- Thermal Insulation: High levels of insulation are used to minimize heat loss or gain through the building envelope.
- Airtightness: The building envelope is designed to be airtight, preventing uncontrolled air leakage and drafts.
- High-Performance Windows: Energy-efficient windows with low-emissivity (low-e) coatings and multiple glazing layers reduce heat transfer and improve thermal comfort.
- Thermal Bridge-Free Construction: Thermal bridges, which are areas of the building envelope with higher heat transfer rates, are minimized or eliminated to prevent heat loss.
- Heat Recovery Ventilation: Heat recovery ventilation systems provide fresh air while recovering heat from outgoing air, ensuring good indoor air quality and reducing energy consumption.
