This Concept Map, created with IHMC CmapTools, has information related to: A2-BUILDING PROBLEMS by Kam Kenn Jhun, Passive design is design that does not require mechanical heating or cooling. It is about making the most of local conditions to make your home comfortable, affordable and sustainable. By paying close attention to all of the aspects below, you can reduce heat entering your home by up to 90%: •insulate ceilings, walls and floors •seal off draughts around windows, doors and any other gaps •provide external shading to north, east and west windows •create ventilation to allow cool outside air into the house Incorporating passive design in your home saves you money, increases your comfort and reduces greenhouse gas emissions from heating and cooling. A high energy conservation rating also adds to the overall value of your property at resale time. ???? Good passive design uses natural heat from the sun and natural cooling to keep your home comfortable. Cross ventilation allows natural airflow to cool your home. Ceiling fans can boost air flow using far less power than air-conditioners. And if you live in a hot and dry climate, an evaporative air cooler may be a cheaper alternative than an air conditioner., Good passive design uses natural heat from the sun and natural cooling to keep your home comfortable.

And if you live in a hot and dry climate, an evaporative air cooler may be a cheaper alternative than an air conditioner. How to create a passive design for a cooler home •Orientate the building for exposure to cooling breezes. •Increase natural ventilation by reducing barriers to air paths through the building. Open up enclosed verandahs and don’t enclose subfloor areas. •Install a roof ventilator. •Provide fans to move air in the absence of breezes. •Choose appropriate windows and glazing to minimise unwanted heat gains and maximise ventilation. •Provide effective shading (including planting trees). Use blinds or screens on verandahs to block sunlight but allow ventilation. Use heavy curtains or blinds to reduce heat transfer through windows particularly on western elevation. •Ensure adequate levels of appropriate insulation are installed. •Choose high thermal mass construction in regions with significant day and night temperature ranges (and low thermal mass construction in regions with a narrower temperature range). •Use light-coloured roof and wall finishes to reflect more solar radiation and reduce heat gain. Several manufacturers now make heat-reflecting roof coatings that claim up to a 20% reduction in ceiling temperatures., Nowadays, we are looking into the account of green building, energy efficiency, low energy consumption building. Green projects should be audited and if something is wrong with the design, that information needs to circulate back to the architect so they can learn from their mistakes. Flexibility often has beneficial results (though I don’t know I’d go so far as to change state policy on that front). And there should besome level of accountability for projects or team members that don’t meet their goals. What gets ignored in building design concept?
