From the options below select an appropriate U value range for a Passivhaus?
0.10 - 0.15 W/m2K
0.21 - 0.27 W/m2K
0.17 - 0.20 W/m2K
0.19 - 0.23 W/m2K
From the options below choose the statement which best defines "Thermal Bridging"
Thermal Bridging is the prevention of heat loss in a building.
Thermal Bridging is when materials that are poorer insulators than surrounding materials come in contact; allowing heat to flow through the path created.
Thermal Bridging is a property that enables building materials to absorb, store, and later release significant amounts of heat.
Thermal Bridging is the transfer of heat from room to room via the MVHR system.
The image above shows a blower window test to check the airtightness level of the structure:
True
False
From the list below, choose the statement which best describes "wicking" of insulation
Wicking is the positive effect on an Insulation's performance caused by air movement.
Wicking is the loss of heat through a structure due to materials that are poorer insulators coming in contact with cold surrounding surfaces.
Wicking is the term given to Insulation when it is performing at its optimum
Wicking is the negative effect on an Insulation's performance caused by air movement.
