Guide to passive solar home design

Guide to Passive Solar Home Design By using the basic physical characteristics and layout of your home you can improve its natural lighting and regulate temperature for indoor comfort Passive solar design can reduce your electricity consumption and reduce your energy bills ?? no matter your climate zone What is Passive Solar Design Passive solar design incorporates features in your home and its natural surroundings that harness the sun ? s low rays in winter and de ect the sun ? s high rays in summer to naturally warm and cool the interior A home ? s orientation elevation room layout materials and surrounding outdoor landscaping all contribute to its passive solar design Unlike active solar heating systems passive solar design does not involve the use of mechanical and electrical devices such as pumps fans or electrical controls to move collected solar heat Instead it incorporates the use of windows walls and oors to collect store and distribute solar energy in the form of heat in the winter and block solar heat in the summer Passive solar homes range from those heated almost entirely by the sun to those with south-facing windows that provide some fraction of the heating load You can apply passive solar design techniques to a new home However you can adapt or update existing buildings to passively collect and store solar heat Elements of Passive Solar Design To design a completely passive solar home you need to incorporate what are considered the ?ve elements of passive solar design Aperture Windows ?? Windows should face within degrees of true south and during winter months they should not be shaded from a m to p m The windows in living areas should face south while the windows in bedrooms should face north In colder climates reduce the window area on north- east- and west-facing walls while still allowing for adequate daylight In warmer climates use north-facing windows along with generously shaded south-facing windows When purchasing windows look for ENERGY STAR quali ?ed windows Absorber ?? The hard darkened surface of the storage element is the absorber This surface ?? such as a masonry wall oor or partition ?? sits in the direct path of sunlight Sunlight hits the surface and is absorbed as heat Thermal Mass ?? Floors and walls that absorb heat are particularly useful for naturally heating homes in colder climates Thermal mass refers to materials that retain or store the heat produced by sunlight The di ?erence between the absorber and thermal mass although they often form the same wall or oor is that the absorber is an exposed surface whereas thermal mass is the material below or behind that surface Heat Distribution ?? Passive solar design allows solar heat to circulate from collection and storage points to di ?erent areas of the house A strictly passive design will rely on natural heat transfer but some applications use fans ducts and blowers to help distribute heat continued CWinter Sun Five Elements of Passive Solar Design
