Passive Solar Precedent Studies

SOLAR PRECEDENT STUDY 01 - POLYSPORTIVE ESTERRI
KEY POINTS - Low cost, low maintenance - 70% of energy acquired by passive solar design - Reflecting shutters - increase solar gain by 20% + act as insulation at night - Natural daylighting + natural ventilation reduce capital maintenance costs - Passive solar design adds 14% to the cost of the building in exchange for energy saving in the long term
ENVIRONMENTAL ANALYSIS Contextual Analysis The building is sited on a South facing slope with sheltering on the North side, and no overshadowing from other buildings. Environmental Section ...demonstrating the many methods of environmental control the building utlilises - the most useful being the openable photovoltaic cell 'shuttering' to the South facing sunspace which also reflects solar radiation into the building.	DETAIL ANALYSIS Winter Day The sunspace to the front of the building receives direct solar radiation and reflected radiation from the photovoltaic cell. This is self powered, raising or lowering itself according to the intensity of the light. Winter Night The shutter closes to retain trapped heat in the sunspace. Solar energy retained in the storage wall heats the space. Trickle ventilation is provided by underfloor duct and a fan at high level

SOLAR PRECEDENT STUDY 02 - BOEGEHUSENE
KEY POINTS - Low cost - 3 Climate Zones for different seasons - Attached sunspace with system of shutters and blinds cuts energy consumption by 40% - Warmed solar ar redistributed to cooler parts of house by simple system
ENVIRONMENTAL ANALYSIS Contextual Analysis The project is a series of two storey terraces houses arranged in blocks of six with South facing sun spaces. Summer Day Blinds protet the sun spaces from solar gain while ventilation to the North and South facades and internal walls provided cross ventilation. Shutters between the sunspace and house are manually operated as the heating requirements dictate. Winter Day The sunspace effectively collects solar radiation and distributes it into the house through the dividing wall. Stack effect carries the heat to the top of the house from where it is redistributed via an electrically powered fan. Winter Night The shutters to the sunspace are closed tight keeping all heat within the confines of the main living area.	DETAIL ANALYSIS Detailed Section Detailed section through junction between fully glazed (single) sunspace and fibre-cement sheeted roof.1000

SOLAR PRECEDENT STUDY 03 - AM LINDENWALDE
KEY POINTS - Curved terrace with sunspace attached to South side - Split level floors increases daylight penetration and promotes circulation of heated solar air throughout the house - Houses cost less than those of a similar traditional size due to design and construction savings.
ENVIRONMENTAL ANALYSIS Contextual Analysis The terraces are curved so that the South facing elevation has a greater area than the North. The terraces are thus at right angles to the street. Winter Day ...the passive solar heating system comes into play distributed warmed air through part of the house contributing to the overall heating demands. Summer Day ...effective cross ventilation of the house enabled by the open plan arrangements and split levels ensures effective cooling is achieved	DETAIL ANALYSIS Terrace plan The sunspace larger South facing elevation permits more solar energy to be collected in the large sunspaces and less lost through the reduced North facing wall.
