CLIMATE
DESIGN CRITERIA AND FEATURESOBJECTIVES
PHYSICAL MANIFESTATION
Resist heat loss Decrease exposed surface area
Increase thermal resistance
Increase thermal capacity (Time lag)
Increase buffer spaces Decrease air exchange rate Increase surface absorptivity
Promote heat gain Reduce shading Utilize heat from appliances Trapping heat
Orientation and shape of
building. Use of trees as wind barriers
Roof insulation, wall insulation and double glazing
Thicker walls Air locks/ Lobbies Weather stripping Darker colors
Walls and glass surfaces
Sun spaces/ green houses/ Trombe walls etc
TREES –wind barrier
Roof & wall insulation
Thick walls
Heavy walls (mud) and a well insulated roof (timber & mud) dampen the variations of indoor temperatures.
Use of glass and trombe wall – heat is stored in the building mass during the day and warm during the night
City of some 25,000 inhabitants
Population triples in size during summer tourist season
OLD LEH• 200 stone, mud and timber houses sandwiched between thick rammed earth walls
• Most well-preserved traditional Tibetan city in the world
• Most significant ensemble of historic Tibetan architecture
• One makes the walls for the first floor, piling up stone and sun-dried brick, • and then places wooden beams and floor joists across the walls to support the second floor walls above them, • and repeatedly adds more wooden beams across them. • Floors and roofs are made of mud treaded on wooden boards. • Roofs are basically flat, being unnecessary to waterproof, since it scarcely ever rains.• Columns are needed midway across larger spans
• First floor - used for stables • Second floor – for family rooms, such as a sitting room, a kitchen, bedrooms, and a Buddhist altar room • A larger house often consists of three floors.
