About Warm Temperate Climate:• Climate with four clearly defined

seasons, including a mild winter and a hot or cool summer.

• Rain occurs all seasons but summer is the wettest time and temperatures then are warm to hot.

• Around the Mediterranean and some parts of central Chile, California and Western Australia, between 30-40 degrees latitude, the winters are generally mild with depressions bringing some winter rain, and summers warm and hot with little or no rain.

Annual Wind Directions:

Passive Design priorities:

• Heating• Ventillation• Lighting• Cooling and Moisture Removal• Protection from summer sun• Inlet for winter sun• Protection from cold winter

winds• Water Conservation

Passive Strategies Used:

• Orientation: 1. Along East-West direction2. Winds from South West strike at 45

deg.• Glazed North façade, upper

clerestory, and lower blinds (aluminium).

• South façade (street side) faces hot, wet weather so it’s covered by triple layered brick wall.

• Pivoting slats for ventilation• Insulating base as well as thermal

sink• Curved roof for diffused lighting,

shade and reduced wind resistance• Gutters for rain water collection

• The bedrooms and living rooms oriented towards north

• Blinds, clerestory and louvred windows on the north :

• Control light• Allows ocean

views• Cuts glaze• Reduces heat

• Open environment provides no natural shelter from wind and sun

• The corrugated steel roof reflects most of the sunlight keeping the interiors cool during summers

• The steel frame with curved steel roof provides strength and durability to the structure as well as gives the tent like feel to the weekend house.

• North facade- steel framed glass wall• Upper portion consists of clerestory

glazing shaded by roof overhangs during summer

• The lower part has metal blinds or louvres which control heat and light.

• Sun angle of winter equinox allows light to flood the interiors

• Curved ceiling directs extra light into the rooms on north.

• The wide open north façade also allows the panoramic view of the sea

• The external light colored paved areas also help in bouncing back sunlight into the rooms.

• Receives wet season monsoon daily afternoon sea breezes

WEST ELEVATIONS

SOUTHERN FACADE• Sealed and opaque against the cold winter

winds by triple layer brick wall which also prevents heat loss at night.

• It has glass clerestory windows 2m above till the roof which allow enough light

• There is only one opening in the kitchen area

• Receives dry season prevailing breezes in the morning

• All the living areas require heating, cooling, and ventilation

• So all the rooms are aligned along the north direction in a linear fashion

• The house sits on an insulated slab• Slab and the back brick wall act as a

thermal sink absorbing winter sun during the day

• At night it radiates it back into the interiors reducing the need for artificial heating.

Ventilation:• The house is one room wide which is

approximately 6 m wide• The circulation corridor and the

wide fenestrations on the north ensure enough ventilation throughout the house

Fenestrations:

Pivoting slats

Roof :Corrugated Steel

Water Conservation• The central spine of the roof directs

the rainwater from the slope to a channel which directs it to the recharge pit underneath on both sides of the roof
