Definition
| In a construction assembly (wall, roof, floor0 there is a conductive material that bridges from the cold zone outside to the warm inside. Some common examples are structural beams and lintels, poorly insulated window frames or the edges of concrete floor slabs |
|
|
Term
|
Definition
| A material of low conductivity is used as a break between the cold zone and the more conductive thermal bridge |

Definition
| Between the neutral zone (horizontal cross-section of building). Above, positive air pressure results in air movement out of a building. |

Term
|
Definition
| The ability of a material to store heat. Also described as heat capacity. |

| What happens in tall buildings with stack effect? |
|
Definition
| There is an issue with IAQ (control, heat transfer, but also with smoke movement and fire control. |

Term
| What is direct solar gain? |
|
Definition
| Solar radiation reached materials and surfaces within the living space and heats the space through direct radiant heat as well as convection and conduction for the heated surface/material |
|
|
Term
| What is indirect solar gain? |
|
Definition
| Radiant energy heats a part of the building envelope that indirectly heats the interior of a building - examples of this are trombe walls, earthen roofs or water tanks |
