What is Passivhaus?

Passivhaus is German for ‘Passive House’, and it is a highly energy efficient building, which requires minimal heat energy to maintain a comfortable temperature all year round. In fact, a Passive House needs up to 90% less energy than the average house. The 10% that is needed is produced predominantly by passive heat sources which include human body heat, the sun’s rays and even the heat coming off household appliances.

What makes it all possible is the high-quality design principles and craftsmanship, combined with other key elements that set Passivhaus construction apart.

• Thermal performance insulation
• High quality windows and doors
• Thermal bridge free design and construction
• Airtightness
• Ventilation with highly efficient heat or energy recovery

At Fraser Millar, we have adopted this method of construction and are Passivhaus certified.

Our mission is to build certified Passivhaus homes in which homeowners have control over their energy consumption, without the worry of ever-increasing energy bills. Also, with less need for fossil fuels, Passivhaus practices are a step in the right direction for Northern Ireland with Fraser Millar leading the way to move the property sector forward and ensuring residents have access to a cleaner, greener and leaner way of living.
