What are some features of a passive house?
Passive design utilises natural sources of heating and cooling, such as the sun and cooling breezes. It is achieved by appropriately orientating your building on its site and carefully designing the building envelope (roof, walls, windows and floors of a home).
What are the 3 aspects of passive solar design?
A strictly passive design will use the three natural heat transfer modes- conduction, convection and radiation- exclusively. In some applications, fans, ducts and blowers may be used to distribute the heat through the house. Control: Roof overhangs can be used to shade the aperture area during summer months.
What are passive solar design principles?
Passive heating design relies on greenhouse principles to trap solar radiation. Heat is gained when shortwave radiation from the sun passes through glass, where it is absorbed by building elements and furnishings and re-radiated as longwave radiation.
What are the 5 passive house principles?
According to the Australian Passive House Association, a Passive House is designed and built in accordance with five simple building-science principles:
- Airtightness.
- Thermal insulation.
- Mechanical ventilation heat recovery.
- High performance windows.
- Thermal bridge free construction.
What are the following is an example of passive solar technology?
6. Which of the following is an example of passive solar technology? Explanation: Solar furnace is a well known example of passive solar technology. It uses concentrated solar power to generate high temperatures for industrial purposes.
What are the benefits of passive solar design?
A huge benefit of passive solar design is that it saves money that would otherwise be spent on utilities toward and heating and cooling bills. It is a clean and efficient use of energy because it is based off of a type of energy that is readily available and occurs naturally.
What are PassivHaus four principles?
These principles are the core ways in which you can differentiate a “normal” home with one that has the PassivHaus badge of approval.
- 1 – High quality insulation.
- 2 – Heat control and robust windows.
- 3 – Airtight construction.
- 4 – Heat recovery ventilation.
- 5 – Thermal bridge free design.
What is the goal of Passive House?
The goal is to design an extremely air-tight building envelope, limiting outside air coming into the building. This allows for the ventilation to be managed mechanically, which dramatically improves indoor air quality without consuming unnecessary energy.
Why is passive solar design important?
Passive solar design takes advantage of a building’s site, climate, and materials to minimize energy use. A well-designed passive solar home first reduces heating and cooling loads through energy-efficiency strategies and then meets those reduced loads in whole or part with solar energy.
