Climate and Building Design
Understanding how the sun moves through the house is key to maximizing energy efficiency.
Working with the sun. Skylights are used to heat and light the double-height bedroom and mezzanine.
High performance double-glazed windows with wooden frames help us conserve energy
When air warms it expands, becomes less dense than the surrounding air, and rises. This process is called convection and is the main process by which heat moves around a room and the house. When rooms are sealed, convection is a sealed circuit of hot air rising over radiators and then sinking as it cools to be heated again.
KEY DESIGN PURPOSES:
Shade all east & west glass in summer. Install reflective insulation to keep out heat in summer.
The Built Environment as a Technological System (Pearce 1999, adapted from Yeang 1995, Roberts 1995)
Frame structures with columns, beams and slab connections.
Aesthetically, timber possesses a natural attractiveness that people readily relate to.
Timber has good compressive strength but is strongest in tension
In general timber has low thermal mass
Timber is a natural insulator due to air pockets within its cellular structure
The sound insulation of walls is usually obtained by providing a barrier of sufficient mass to absorb the sound energy.
Timber is an organic material and deteriorates due to weathering.
Recorded Historical Perspective
Materials those have, the lowest possible negative impact to the natural environment, minimal net negative impact to the natural environment, and maintain some reasonable level of human satisfaction in their technological and socioeconomic performance could be defined as "eco-materials".
