Question 1 of 5

1. Question
What is meant by “specific annual energy demand” for a Passive House? Mark the correct answer:
- The amount of heat needed in an average building which is specific to your geographic location
- The amount of heat produced annually by your appliances
- The total amount of heating energy needed over the heating season, divided by the usable floor area
- The total annual cost of heating your building

Question 2 of 5

2. Question
Mark all true statements about heating a cool climate-zone Passive House:
- It is essential to provide a source of space heat under all large windows to ensure comfort on cold nights
- Space heating should never be direct electricity
- The space heating load should only be determined by the PHPP
- Rooms with extra comfort requirements (e.g. bathrooms) should be provided with extra heating capacity
- It is not possible to heat a cool-climate building solely via ventilation supply air
- A supply air heating system requires extra ducting to all rooms, compared to a ventilation system which does not use supply air heating
- It may be possible to both heat and cool a Passive House using a minisplit heat pump, in milder climates

Question 3 of 5

3. Question
What is the maximum specific heating load that should be distributed via a supply air heating system, according to the international Passive House Standard?

- 0.1 W/m2
- 10 W/m2
- 100 W/m2
Correct

Question 4 of 5

4. Question
Which of these statements about heating load are correct?
- All buildings have a design heating load
- For a Passive House, the heating load must be calculated using PHPP
- Both heating load and annual heat demand are expressed as W/m2
- The heating load for a Passive House building is the same size as the ventilation air demand
- A Passive House can be defined as a building in which the heating load can be supplied solely by the ventilation supply air
- The heating load in a building can be supplied by a variety of different heating systems
- The heating load in a Passive House is highly dependent on the thermal mass of the building
Correct

Question 5 of 5

5. Question
Which of these statements about heating in a Passive House is correct?
- Adequate heating can often be supplied to each room via the ventilation air supply
- It is important to heat every room in a Passive House to the same temperature
- Woodstoves produce too much heat energy to be used in Canadian Passive house buildings
- The space heating demand is normally 8 – 10 times lower than for normal Canadian construction
- Specific heat demand refers to the heat demand per square metre of usable floor space (i.e. Treated floor area)
- Radiant heating systems are preferable in Passive House buildings as they produce higher comfort levels
