Passivhaus building is the epitome of energy-efficient design, built to meet the globally recognised Passivhaus standard. The primary focus? Unparalleled thermal comfort for occupants while drastically reducing energy consumption.
Why Choose the Passivhaus Standard?
Building to the Passivhaus standard offers a range of compelling benefits:
Energy Savings: Reduce heating and cooling demands—and costs—by up to 90%.
Year-Round Comfort: Enjoy consistent, draft-free thermal comfort in every season.
Exceptional Build Quality: Achieve higher construction standards with meticulous attention to detail.
Eco-Friendly Design: Minimize your building’s carbon footprint compared to traditional construction.
For context, the Passivhaus standard limits annual heating demand to just 15 kWh/(m²a). Compare this to a typical 1950s two-bedroom end-terrace house, which may have an estimated heating demand of 458 kWh/(m²a)—a stark difference that showcases the energy efficiency of Passivhaus design.
How Does a Passivhaus Stay Warm?
Passivhaus buildings leverage smart design principles:
Optimal Orientation: Maximize natural solar gain.
Mechanical Ventilation Heat Recovery (MVHR): Efficiently recycle and distribute heat, eliminating the need for traditional heating systems.
Backup Heating: Optional systems can provide a small boost during extreme cold snaps, ensuring comfort in every scenario.
Flexibility in Construction and Finishes
Passivhaus is as versatile as it is efficient. Whether you prefer timber, steel, masonry, or other materials, the standard can be achieved without limiting your creative vision or the choice of high-quality finishing materials.
Is Passivhaus a New Concept?
Not at all. The first Passivhaus was built in Germany in 1991, following ground breaking research by physicist Wolfgang Feist and structural engineer Bo Adamson in 1988. Today, it remains a gold.
standard in sustainable architecture worldwide.
