Sustainble house

  1. 1. Sustainable building:  Erection of health environment  Limits the negative impact on the environment  Re-used
  2. 2. Conditions Minimizing transportation roots Minimizing pollution Site beneficence Climate (sun direction ,wind, temperature, rain …) Minimize cost Local materials Comfortable for users Re-usable materials
  3. 3. Principles of sustainable house Conserving energy Energy conservation can be achieved through increased efficient energy use , in conjunction with decreased energy consumption. In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design or climatic design because, unlike active solar heating systems, it doesnt involve the use of mechanical and electrical devices.
  4. 4. Energy conservation strategies relating to buildingorientation:• Maximizing north and south façade exposure for daylightharvesting to reduce lighting electrical loads• Using southern exposure for solar heat gain to reduceheating loads in the heating season• Using shading strategies to reduce cooling loads caused bysolar gain on south façades• Turning long façades toward the direction of prevailingbreezes to enhance the cooling effect of natural ventilation• Turning long façades in the direction parallel to slopes totake advantage of cool updrafts to enhance naturalventilation• Shielding windows and openings from the direction of harshwinter winds and storms to reduce heating loads• Orienting the most populated building spaces toward northand south exposures to maximize day lighting and naturalventilation benefit• Determining building occupant usage patterns forpublic, commercial, institutional, or residential buildings, andhow occupants will be affected by the building orientation, bytime of day, on different exposures
  5. 5.  Protect and Conserve Water In many parts of the country, fresh water is an increasingly scarce resource. A sustainable building should use water efficiently, and reuse or recycle water for on-site use, when feasible Use Environmentally Preferable Products A sustainable building is constructed of materials that minimize life-cycle environmental impacts such as global warming, resource depletion, and human toxicity. Environmentally preferable materials have a reduced effect on human health and the environment and contribute to improved worker safety and health, reduced liabilities, reduced disposal costs, and achievement of environmental goals. Enhance Indoor Environmental Quality (IEQ) The indoor environmental quality (IEQ) of a building has a significant impact on occupant health, comfort, and productivity. Among other attributes, a sustainable building maximizes daylighting; has appropriate ventilation and moisture control; and avoids the use of materials with high- VOC emissions. Additionally, consider ventilation and filtration to mitigate chemical, biological, and radiological attack.
  6. 6.  1. Water conservation Use water efficient appliances and fittings, such as 3-star ( or more) showerheads and water pressure-limiting devices, and include a rainwater tanks to supply water for use with gardens, toilets and laundry. 2. Natural heating and cooling (passive solar design) Good passive solar design allows your home to respond to its local climate through natural heating in winter and cooling in summer e.g. good orientation and room zoning, capturing breezes for cross-ventilation, appropriate insulation, shading (e.g. sufficient eaves), building materials (lightweight construction/thermal mass), and fixtures and finishes (e.g. skylights and window treatment). Incorporation of passive design reduces the need to rely on air conditioners/heaters. It can also indirectly promote natural daylighting and improve indoor air quality with circulating breezes providing fresh air inside the home. 3. Energy and greenhouse efficient water heating Install a solar, natural gas or electric heat pump hot water system to lower energy bills and reduce the single largest source of greenhouse emissions in the household. 4. Future-proof The living area and at least one bedroom and toilet on the entry level should be readily accessible from the front boundary or car space to accommodate your changing housing needs as you get older.
  7. 7.  5. Safe floors Design floors and showers to be step-free (hobless). Use floor surfaces that are slip resistant to guard against injuries. 6. Address the street An easy to read house number at the front of your property makes it easy to find. Good external lighting and separated driveway and pedestrian entries also makes it safer. 7. Casual surveillance Design your home to have easy surveillance to play areas and the street from the main living area and kitchen for better security. 8. Long-term maintenance Reduce the repair and ongoing maintenance costs of your home by using low maintenance materials. 9. Indoor air quality Avoid materials that contain volatile organic compounds (VOC’s), such as paints/finishes and adhesives, which can cause irritation and allergies, and impact poorly on your health. 10. Outdoor living Include permanently covered outdoor play and entertainment areas with a good relationship to indoor spaces to maximise your home’s access to Queensland’s favorable lifestyle and climate.
