Transcript of Climate zone leh, ladakh cold and sunny climate
LEHMountainous region
Little vegetation
Considered to be a ‘Cold Desert’
COLD and SUNNY type of climate is experienced here.
TEMPERATURE VARIATIONS• Summer
during day : 17 - 24°Cduring night : 4 - 11°C• Winterduring day : 7 - 9°Cduring night : -14 – 0 °C
Relative humidity – consistently low : 10-50%Winds – occasionally intenseSky is fairly clear throughout the year Cloud cover is less than 50%
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
Materials that heat up fast
Decreasing the ventilation
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.

METHODOLOGY
1.SITE:
a) LANDFORM
b) OPEN SPACE AND BUILT FORMS
c) STREET WIDTH AND ORIENTATION
2.ORIANTATION AND PLANFROM
3.BUILDING ENVELOPS
a) ROOF
b) WALLS
c) FENESTRATION
d) COLOR AND TEXTURE
4.TECHNIQUES
a) GLAZING
b) TROMB WALL
c) WATER WALL
d) ROOF BASED AIR HEATING SYSTEM
e) SUNSPACES
SITE
a) LANDFORM:
In cold climates,heat gain is
desirable.Hence,building should be located on the south
slope of a hill or mountain for better access to sollar
radiation.
