VENTILATION AND AIRFLOW
- Does BERS limit the number of downlights per assessment?
- Can BERS Pro model stack driven ventilation?
- I would really like to be able to change the number of air changes per hour (due only to mechanical ventilation) in different zones to size the mechanical ventilation requirements.
- Why is it that adding a ceiling fan can make a room’s star rating different by anywhere between a 0.5 star - up to 2.5 stars?
- I am having trouble getting a house with a traditional stone fireplace to pass as the unsealed chimney has a significantly negative impact on the star rating.
- How do I model a permanent opening between a living and kitchen open plan area?
- How do I model a bank of louvres modelled next to a bedroom door opening on to the corridor?
- When you select tiles on a roof with no foil under, does this constitute a ventilated or discontinuous roof space?
- Conversely, if the roof is tiled and sarked, is it now considered unventilated/ continuous?
- I am about to do a BERS assessment on a high-rise unit complex. As the units get higher do I change the wind shielding?
- How do I model night time air flushing?
- How do I model whole house fans which change the air in rooms 35 to 45 times every hour and in roofs up to 60 times an hour? (...it can ventilate every room in the house or be directed to ventilate certain rooms.)
- The plan has wall mounted oscillating fans. Is a ceiling fan an acceptable substitute in the context of the program?
- Does the system where external louvres flap shut under gravity constitute a sealed exhaust fan?
- Where we have units above the car park (mechanically vented and with screen doors) do we nominate an “enclosed sub-floor”? Is there a ventilation rate we should approximate for these situations?
- What is happening in the assessment, between adding a vent of unflued gas heater v/s adding a wall or ceiling vent?
