PassivHaus design consultancy
"PassivHaus" is a building design philosophy which suggests that developments should minimise their energy consumption through the use of measures such as a highly insulated thermal envelope, increased use of solar gains, a high degree of airtightness and energy efficient appliances.
Further, PassivHaus is more than energy reduction; criteria are based on levels of comfort.
In order to be PassivHaus certified, a building must have:
- A heating requirement of less than 15kWh/m2/yr;
- An airtightness n50 value of less than 0.6ach;
- An overheating frequency of less than 5%;
- An internal surface temperature of more than 17 degrees; and
- A primary energy demand of less than 120kWh/m2/yr.
Through experience and in using the PassivHaus Planning Package (PHPP), Phlorum can assist designers in achieving the above standards for their projects.
