1.1.2. Efficient Building Envelope

Try these first

1. 1.

   What primary function does insulation have in a building?

   Hint

   Think about keeping warm in winter.

2. 2.

   Name one material that can improve a building's airtightness.

   Hint

   Consider sealing gaps.

3. 3.

   What does high-quality insulation primarily achieve?

   • Increases heat gain
   • Minimizes heat loss
   • Adds weight to the building

   Hint

   Think about winter and summer.

4. 4.

   True or False: Airtight construction helps prevent unwanted drafts.

   • True
   • False

   Hint

   Focus on comfort.

5. 5.

   Calculate the energy savings if a building transitions from single-layer windows to triple-glazed windows, assuming an average heating cost reduction of 30%.

   Hint

   Consider the total area and volume of heating needed.

6. 6.

   Propose a strategy for retrofitting an older building to improve its energy efficiency by optimizing the building envelope.

   Hint

   Account for the climate of the building's location.
