ii) Passive Systems The Healthy Home Kitchen cooking area located outdoors - this allows for fire separation and improves indoor air quality External bath house reduces risks of dampness and mould issues from water systems Openings allow for fresh air movement and the addition of the solar venti improves indoor air quality The sunny north east aspect of the living area allows for warmth in winter mornings whilst the work desk and computer monitor is on the southern façade for minimal glare Maximum natural day lighting fit for purpose Passive design appropriate to specific climatic conditions of region (Zone 2 warm humid summer, mild winter) Considered and adaptable building envelope Orientation for solar heating and cooling Eaves and vegetation to building elements provide shading House at minimum depth for cross ventilation Site exposure to breezes Screened and shaded outdoor living area Human thermal comfort addressed in building envelope design and façade treatment North, combination of fixed and adjustable shading with deep eaves East/ West, adjustable vertical screens SE & SW, additional planting to assist with thermal comfort NE & NW, adjustable shading Passive Heating Floor plan zoning and separation to allow for heating depending on needs Thermal mass ideally located on northern half of house where it will absorb most passive solar heat Option to close vertical circulation zone to prevent heat escaping and to contain it in the lower level during winter days Ceiling fans to run in reverse Solar venti system pushes warm air in to internal space as soon as it is light in winter
Water tank acts as a wind break preventing strong cold westerlies affecting the kitchen area in winter Louvers capable of being oriented to deflect cool breezes Glazing on southern façade to have low emissivity and U value, this coating would allow reflected daylight to penetrate the house but would reduce the amount of long wave length infra red heat that could escape through the window Appropriate window covering made from ply panels to cover the glazing at night during winter Passive Cooling Maximised openings on upper level to allow for summer ventilation Views are an important aspect of the scheme and provide a broader connection to the neighbourhood, house orientation capitalises on views whilst minimising heat gain in summer and glare Heat loss facilitated through air movement and cooling breezes Lifestyle adaptations such as the external kitchen prevent excessive heat gain indoors, the shading and weather protection provided means they can be used all year round Vertical circulation acts as a heat stack to encourage convective air movement (this is better at cooling the house than its occupants Evaporative cooling system, large amounts of heat are consumed by water as it evaporates drawn from surrounding air causing cooling, this cool air is then sucked in to the house by convective currents iii) Systems Application
