The basic aim was to build a long-lasting, beautiful and sustainable home by minimising energy required for heating, cooling, and efficient water use. Passivhaus is a network of highly experienced German and Swiss trained developers keen to minimise fossil energy used when building a home and the ongoing energy needs which contribute to global warming. Building a home in Cottesloe to international standards regarding energy efficiency and comfort was a great experience for Andrew. He recently completed WA’s first PassivHaus using our own structural insulated panels. He now works in Perth, specialising in building homes with environmentally friendly products. Andrew was appointed Project Coordinator for an expansion to Sydney’s International Airport Terminal Building and then transferred to the UK and Switzerland to help integrate three European businesses. He worked on engineering construction projects in Belgium and New Guinea and completed an MBA in France. ![]() Other control approaches include electronic sensing devices, such as a differential thermostat that signals a fan to turn on operable vents and dampers that allow or restrict heat flow low-emissivity blinds operable insulating shutters and awnings.Structural Insulated Panels (SIPs) A Builder's take with Andrew Abercromby ( Consortium Builders)Īndrew Abercromby qualified as a Civil / Environmental Engineer at UWA. ![]() Properly sized roof overhangs can provide shade to vertical south windows during summer months. Darker colors absorb more heat than lighter colors, and are a better choice for thermal mass in passive solar homes. Radiation is what you feel when you stand next to a wood stove or a sunny window and feel its warmth on your skin. Convection is heat transfer through a fluid such as air or water, and passive solar homes often use convection to move air from warmer areas - a sunspace, for example - into the rest of the house. Conduction occurs when heat moves between two objects that are in direct contact with each other, such as when a sun-heated floor warms your bare feet. In some homes, small fans and blowers help distribute heat. Solar heat is transferred from where it is collected and stored to different areas of the house by conduction, convection, and radiation. In well-insulated homes in moderate climates, the thermal mass inherent in home furnishings and drywall may be sufficient, eliminating the need for additional thermal storage materials. Make sure that objects do not block sunlight on thermal mass materials. Other thermal mass materials such as water and phase change products are more efficient at storing heat, but masonry has the advantage of doing double duty as a structural and/or finish material. Thermal mass in a passive solar home - commonly concrete, brick, stone, and tile - absorbs heat from sunlight during the heating season and absorbs heat from warm air in the house during the cooling season. ![]() During the spring, fall, and cooling season, the windows should be shaded to avoid overheating. Be sure to keep window glass clean. Typically, windows or other devices that collect solar energy should face within 30 degrees of true south and should not be shaded during the heating season by other buildings or trees from 9 a.m. ![]() To be successful, a passive solar home design must include some basic elements that work together: Well-designed passive solar homes also provide daylight all year and comfort during the cooling season through the use of nighttime ventilation. The ideal ratio of thermal mass to glazing varies by climate. The share of the home’s heating load that the passive solar design can meet is called the passive solar fraction, and depends on the area of glazing and the amount of thermal mass. In simple terms, a passive solar home collects heat as the sun shines through south-facing windows and retains it in materials that store heat, known as thermal mass.
