Understanding Passive House

What is a Passive House? • A Passive House is a building in which a comfortableinterior climate can be maintained without active heatingand cooling systems. The house heats and cools itself, hencethe term “passive”. [FEIST 1988]

Key Elements of a Passive House

1. Optimised Orientation & Shape,

2. An Enhanced Building Envelope, Including:

- Super Insulation, Air-Tightness & Reduced Thermal Bridging,

3. PH Approved Windows & Doors,

4. PH Approved MVHR Systems,

5. Reducing the Buildings Energy Demand.

6. Meet the reduced heat demand with passive sources:- Solar gains & internal gains

Calculations: Performance is verified by the use of the PHPP calculation tool.

Passive House Criteria:

Criteria New Build (Dom/Non-Dom) Retro-Fit

Space Heating Demand: ≤ 15 kWh/(m²a) ≤ 25 kWh/(m²a)Heating Load: ≤ 10 W/m² ≤ 10 W/m²Primary Energy Demand: ≤ 120 kWh/(m²a) ≤ 120 kWh/(m²a) Pressure Test Result ≤ 0.6 ach ≤ 1.0 ach Overheating Frequency: ≤ 10% ≤ 10%

• Passive House is a comfort standard as well

as an energy standard.

• Passive House construction adopts a fabricfirst approach

• Can be used for any type of building
