Sustainable Buildings - Architectural Considerations

2019-07-22

Architecture and Sustainability


One of the key factors in improving the sustainability of a project is understanding the
energy requirements of a building. Buildings such as houses, shops, offices and with
Other uses account for 40% of world energy consumption and 36% of greenhouse gas
emissions according to the European Commission (2010,2013).

Achieving energy-efficient building design is the way to improve sustainability :) 

Solar control

Construction project that uses architecture to minimize energy consumption and improve
thermal comfort.

• Building envelope design should seek to control solar radiation absorption and its
effects within the future building;
• Sun protection and surrounding shading to reduce the incidence of direct solar
radiation;
• Optimization, building compactness and window to wall ratio.

Thermal Control

Thermal exchanges between buildings and the outdoor micro-climate will depend on:
• Temperature difference between indoor and outdoor
• Exposure and thermal properties of external building elements.
• Wall cavities
• Thermal insulation
• Reflective external materials is to prevent heat gain

Passive cooling


• Passive cooling is most appropriate for releasing heat in buildings in hot climates;
• Evaporative cooling of outdoor air supplied to the building for ventilation;
• Radioactive or convective cooling to cool the building structure;
• Ventilation provides fresh air supply necessary for occupant health and building hygiene.

Cooling Strategies


• Passive cooling is most appropriate for releasing heat in buildings in hot weather.
• Evaporative cooling of outdoor air supplied to the building for ventilation
• Radioactive or convective cooling to cool the building structure;
• Ventilation.

Natural ventilation

  • Process of feeding and removing air through an internal space without the use of mechanical systems.
  • Outside air flow to an interior space as a result of pressure or temperature differences.
