Diurnal Temperature
➢ The diurnal (night time and day time) temperature difference ranges from 20C to 70C, not a very large range.➢ The average summer night-time temperatures are largely above the adaptive thermal comfort temperature requirement of 22 to 240C➢ For only 3 months of the year (and only marginally so), does the diurnal temperature span the Thermal Comfort Zone (with a reference point
of 230C; thus the strategy of providing high thermal mass for the buildings (to help absorb the heat during the day and prevent it from warming the interiors will NOT work.
➢ Similarly, night-time cooling by opening the windows and doors will NOT help remove the heat from the indoor space. And indoor temperatures thereby achieved will NOT be low in the morning.
➢ Insulation, rather than Thermal Mass, will be a more conducive heat gain reduction strategy for this climate.

Seasonal Temperature & Humidity Summary
➢ The building will be occupied during day-time only. Hence, it is more important to ensure comfortable conditions during the day and night.➢ Temperatures remain high during the day for summer. Hence, it is essential to reduce heat gain inside the building.➢ Winter temperatures are low. Hence, reduction of

Monthly Temperature & Humidity Summary
➢ Relative Humidity (RH) in the day time ranges between 25%-77% on a monthly average basis; during periods of high day time temperature however, RH is moderate and hence evaporative cooling is a useful strategy for those months reach thermal comfort conditions by adding moisture to the air
➢ Night time RH is seen to be higher, in general, than day time RH; it ranges from 35%-85% on a monthly average basis. During periods of high night time RH, air temperatures are low and hence artificial cooling is unlikely to be needed. During higher night time temperature periods, RH is sufficiently low to permit use of evaporative cooling to reduce air temperature.
➢ Dehumidification is marginally required for some monsoon days.

➢ Temperatures are high from 8 AM onwards to the end of day, beyond 6PM. ➢ Shading is required from 8AM till 6 PM for all summer months➢ Considering the sun angles, horizontal shading (overahangs) will be useful in North and South. Vertical shading (boxing, fins) will be useful in
East and West.

Wind Analysis -Non-Monsoon
➢ Winds are predominantly from West and North-East from October to June (non – monsoon winds).➢ Wind temperatures are high from the West. North-Easterly winds are cooler. ➢ Wind speed from the Northeast is 8m/s (18 mph). This is considered to be a ‘moderate breeze’ on the Beaufort Scale . ➢ Wind from Northeast can help with cooling through cross-ventilation.

Annual Thermal Comfort – Statistical ➢ Thermal comfort
can be maintained in naturally ventilated spaces considering adaptive thermal comfort zone during February, July, August, September, October
➢ It is too warm or hot in March, April, May, June and temperatures need to be reduced to meet thermal comfort requirement.
➢ Temperature falls below thermal comfort conditions during November December, and January.

72
Monthly Thermal Comfort - Statistical
➢ Thermal comfort conditions are not met for most operating hours from March to June (warm, hot), and November to January (cold)

73
Annual Passive Strategy Distribution - Statistical
➢ Thermal comfort conditions can be met through passive measures to help: Natural Ventilation (28%), Mild Cooling (21%)
➢ Dehumidification can help meet comfort conditions. However, dehumidification is useful only during the monsoon. During this season, it is more important to protect from heavy rainfall and prevent mould growth through cross-ventilation.
➢ Mild cooling can be achieved through passive design measures to reduce heat gain as well as through measures to increase humidity during the dry months.
➢ It is necessary to provide cooling through active system for 4 only % of operating hours.
Source: http://www.carbse.org/resource/tools/
74
Monthly Passive Strategy Distribution - Statistical
➢The primary cooling strategy during non-adaptive-comfort months of March, April, May and June is Natural Ventilation and Mild Cooling or Cooling. Dehumidification
➢Dehumidification is essential during July to September, and some of these conditions can be achieved by forced ventilation (induced or forced draft)

VENTILATION ANALYSIS

Wind Analysis
Summer
➢ Wind temperatures are high during the summer from March - May. The temperatures are between 27C-38C, with temperatures >38C during May. ➢ Winds blow from West and North-West for most hours during the summer. The average wind speed is 4 m/s with highs of 8m/s - 10m/s. An average
speed of 4m/s generates a gentle breeze as per the Beaufort scale. ➢ These winds are relatively dry with less than 50% humidity. ➢ As the winds during the summer are hot, it is essential to cool down the winds before they enter the interior spaces. ➢ As the winds are not very strong only natural breeze will not help in cooling.
91
Wind Analysis
Monsoon
➢ Wind tempreatures are high during the monsoon from June-September. The wind temperatures are between 27C-38C. ➢ Winds blow from the West and South-West during the monsoon. The average wind speed is 6m/s with highs of 10m/s and 12m/s. The average wind
speed of 6m/s is sufficient for a moderate breeze. ➢ The winds have high humidity (>50%) during the monsoon with humidity above 70% in July and August. ➢ The winds are stronger during the monsoon and can help with cooling even though the temperature is high. ➢ Only the natural breeze will not be sufficient for cooling as the winds are warm and humid.
92
Wind Analysis
Winter
➢ Winds blow predominantly from East and North-east during winter from November - February. The wind temperatures are cool between 0C-21C. ➢ The average wind-speed is 2m/s with highs of 6m/s. The average wind-speed will not result in a breeze as per the Beaufort scale. ➢ The winds have average humidity during the winter. ➢ The winds are cool, have moderate humidity and are not very strong during the winter. This can be comfortable without a mechanical system. ➢ t will be better to avoid creating drafts during the winter to prevent discomfort.

94
Wind Analysis
Summary
➢The wind temperatures are high (27C-38C) during the summer and monsoon and the wind speeds are sufficient to create a breeze. However, it will be beneficial to cool the winds prior to entering the interior spaces.
➢As the winds have average or low humidity during the summer, cooling can be provided by adding moisture to the winds through evaporative cooling.
➢Windows aligned perpendicular to West and North-West will be most suitable for natural ventilation during summer and monsoon.
➢Necessary to provide sufficient overhangs to the windows in West to protect from heavy rainfall and still allow breeze in.
➢Winds are low-speed during the winter. Hence, it is not essential to provide buffers to protect from the cold wind during the winters.
