ARCHITECTURE

(a). SITE

Mahagun Moderne at plot no. GH-02, Sector 78, Noida, Uttar Pradesh situated at

latitude 28 33’ 41.87” N and longitude 77 23’ 13.41” E at 199 m above MSL.

(b). CLIMATOLOGY

Noida has composite climate (refer climate zone map of India). Composite climates

are neither consistently hot-dry neither consistently warm-humid. Their

characteristics changes from season to season, alternating between long hot, dry

periods to shelter periods of concentrated rainfall and high humidity. Significant

differences in temperature, humidity, wind, sky and ground conditions can easily be

appreciated.

A third season can be considered having dry sunny days and uncomfortable cold

nights which is referred to winter.

During the cold season the effective temperatures are much lower than in the two

warmer seasons (warm-humid and hot-dry) and physical comfort will depend on the

prevention of heat loss from the body, especially at night. In the warm seasons the

heat dissipation is inadequate and our attempt should be to increase it as much as

possible, but in cold season it may become excessive, creating a sensation of cold

discomfort.

(c). DESIGN CRITERIA

Climate with changing seasons set a difficult task. In order to develop optimum

design standards which are appropriate to composite climate as a whole it is

necessary to establish some form of weighting whereby priorities can be allocated.

Such weighting system can be based on length of different seasons on relative

severity of the condition and their correlation of living pattern.

The results show that, taken singly cold season is the most important for thermal

design. It outweighs two hot seasons put together. However where the design

solution are similar for the hot-dry and cold-dry seasons, their pre-dominance over

warm-humid season is even more pronounced. On the basis of such an analysis

design standards can be formulated for composite climate of Noida.

(d). FORM AND PLANNING

Orientation of building and of its major openings can greatly influence the solar heat

gain, thus it is carefully considered. North and South facing vertical walls receive the

least amount of radiation. Building under expansion have orientation to the north

and south direction so that longer walls shall not faced east or west direction.

Major openings are on N-E or S-W wall. Openings are majorly covered by horizontal

projection of balconies having 1.5 m wide. The arrangement would reduce incident

solar radiation on fenestration.

(e). EXTERNAL SPACES

Larger projecting (wide) balconies have been suggested as outdoor living area which

shall be useful for warm-humid (monsoon) season. It can also be asset in hot season

as this shall protect fenestration from direct solar radiation and in cold season

balconies can be used in day time to take advantage of the sun.


Landscape courtyard between the buildings shall be more pleasant outdoor space

for most of the year to allow sun penetration during the winter months but provide

shading in the hot season

(f). ROOFS ANDWALLS

For continually occupied building the task in two folds

1. To limit the heat admitted during the strong sunshine hours.

2. To store some heat to be re-emitted during the cold period.

The retention of night time low wall temperature is desirable in the hot dry seasons

but same thermal properties will be useful in cold season to retain the heat of the

day for the uncomfortably cold nights.

External walls are therefore will be constructed of AAC blocks / RCC. AAC block withexternal plaster in cement motor has thermal insulation property which shall serveabove purpose.

The roof is by far more important as it receives the greatest amount of radiation.

Roofs shall be RCC with Reflective white color ceramic tiles and insulation.

(g). SURFACE TREATMENT

The prevention of heat entering through the outer surfaces of walls and roof at a

fundamental rule. Walls exposed to sun during hot & warm shall be painted in light

color.

(h). OPENINGS

Orientation of major openings are on north-south to utilize cooling effect of

prevailing breezes during the warm humid seasons and it will also help to
