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.
Managun ModernePLOT NO. GH-02, SECTOR 78, NOIDA
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
