At our Casa Aguila project in Ramona, we are working towards building San Diego County’s first Certified Passive House. Here’s a little bit about the passive design, first developed in Germany:
- It employs continuous insulation through its entire envelope without any thermal bridging.
- The building envelope is extremely airtight, preventing infiltration of outside air and loss of conditioned air.
- It employes high-performance windows (typically triple-paned) and doors
- It uses some form of balanced heat- and moisture-recovery ventilation and uses a minimal space conditioning system.
- Solar gain is managed to exploit the sun’s energy for heating purposes and to minimize it in cooling seasons.
- Superinsulation and airtight construction provides unmatched comfort and even in extreme conditions.
- Continuous mechanical ventilation of fresh filtered air assures superb air quality.
- A comprehensive systems approach to modeling, design and construction produces extremely resilient buildings.
- Passive building is the best path to Net Zero and Net Positive buildings because it minimizes the load that renewables are required to provide.
