Study Notes

Passive Design Strategies

  • Passive design strategies work with the local climate to maintain a comfortable temperature in the space.
  • They reduce or eliminate the need for additional heating or cooling depending on the location.
  • Good passive design often relies on an active occupant to work properly.

Benefits of Passive Design Strategies

  • Energy efficiency
  • Indoor comfort
  • Health and well-being
  • Durability and longevity
  • Affordability
  • Sustainability

Key Passive Design Strategies Elements

  • Building orientation
  • Building form
  • Door and window openings
  • Building envelope
  • Thermal mass
  • Landscape
  • Roof

Malaysian Climate Context

  • Malaysia has an equatorial weather pattern due to its geographical position.
  • The climate is hot and humid.

Traditional Houses in Malaysia

  • Vernacular architecture refers to a type of architecture that is indigenous to a specific time or place.
  • Vernacular houses are the everyday dwellings of the local people.
  • They evolved according to different cultural settings and are the results of long-term modification, adaptations, shared experiences, and innovations.
  • Vernacular houses use local materials, and the function of the building is the dominant factor.

Case Studies

  • Al House of Sabah
  • The Longhouse of Sarawak
  • Factory in the Forest by Design Unit Architects Sdn Bhd
  • Permeability House by Tangu Architecture

Vernacular Needs

  • Technology
  • Culture
  • Climate

Orang Asli Forest Dwelling

  • The Orang Asli are indigenous people of peninsular Malaysia.
  • Their dwellings were designed for basic shelter, not for storing material goods.
  • House building never required professional skills.
  • House structures have evolved only minimally over the centuries, from nomadic to semi-permanent settlements.
  • Cengal and petaling are used for the standing poles because they are not vulnerable to termites.
  • Poles are driven into the ground to a depth of 40 cm measured from elbow to fingertips.
  • Edge beams and roof joists are lashed to the standing poles with rotan (cane).
  • Atap (thatch) roofs are made from palms that are woven.
  • Bamboo is commonly used for the walls.
