  1. 1. HyderabadHyderabad Hyderabad is the capital of the state of Andhra Pradesh and is one of the fastest growing economic states in India. The city is situated at an elevation of 544 meters. The average temperature during the months of summer is anywhere around 40 'C and in the months of winters the average temperature is about 16 'C. Best time to visit the state of Hyderabad is during the months of September to March. Climate: Tropical wet and dry Summers: Average Maximum Temperature: 40 deg C Average Minimum Temperature: 25 deg C Winters: Average Maximum Temperature: 28 deg C Average Minimum Temperature: 13 deg C Annual Rainfall: 79 cm (approximately)
  2. 2.  It remains fairly warm most of the year.  Receive less rainfall in the monsoon.  Temperatures come down in the months of December and January and the nights become quite cool in and around the Hyderabad city.  During the summer months, the mercury goes as high as 42° C while in winters the minimum temperature may come down to as low as 12° C. ClimateClimate Rainfall More than 75 per cent of the rainfall is received during the south-west monsoon season, i.e., from June to September, July being the month when it rains. September is the month, when there are rains. The south-west monsoon sets in by the 7th of June. Its advent is sudden and the rainfall increases from less than 5 per cent (of the annual) in May to 15 per cent in June. Excessive Rainfall In the case of Hyderabad, out of 6 years of excessive rain, as many as four years (1903, 1915, 1916 and 1933) were with rainfall of more than 150 per cent. Generally speaking, 1903 was a year of more than 150 per cent of rainfall. Cloudiness June to October is the period when more than half of the sky is covered with clouds, while only about 2/8 of the sky is clouded from January to March. Half of the days in July and August have overcast skies. About 10 to 13 days in the months of January, February and March, the skies are free from clouds in clear weather.  June to November are the months of monsoons and temperature goes down at times.  Thus, for most parts of the year the weather and climate of Hyderabad remains fairly moderate.
  3. 3. TemperatureTemperature RelativeRelative HumidityHumidity Humidity in the morning is very high exceeding 80 per cent from July to September. In the dry months of March, April and May, humidity is generally low with an average of 25 to 30 per cent and decreases to 20 per cent at individual stations. During the summer months, the mercury goes as high as 42° C while in winters the minimum temperature may come down to as low as 12° C.

Green Building TourGreen Building Tour  Central courtyard.  Roof garden - Protects heat penetration, cuts down heat-island effect  High performance glazing to bring in natural light while minimizing heat ingress.  Usage of light glazing and vision glazing.  Jali (Perforated) wall for bringing in natural light as well as ventilation .  Energy saving system.
  8. 8. CourtyardsCourtyards The courtyards act as "light wells," illuminating adjacent work areas. When this light is not sufficient, sensors trigger the deployment of efficient electric lights. Dimmers automatically control the illumination levels, turning the lights off when they're unnecessary. Also, occupancy sensors prevent a light from being switched on at an unoccupied workstation.
  9. 9. Internal Lighting: Difficult in the lower storey. Ventilation: Difficult conduction of supply air. In summer: Danger of over heating in the upper storey. Particular characteristics: Access zone. Open to one side Lighting: Good. Ventilation: Good. In summer: Effective shading required. Particular characteristics: Sound insulation. In this set of courtyards the wind enters in one direction. The other courtyard may be hot because of the temperature as a result the cool air replaces it. The hot air being lighter than cold air rises up making the place cooler and above the terrace gardens keep the temperature down forcing the hot air to rise up further.

  12. 12. This material will most significantly reduce penetration of radiation from the reflecting side to the non-reflecting side (penetration of 11-37% of total striking radiation).  Such glazing is used in this building where it is desir-able to maintain eye contact with the outside as well as to prevent penetration of radiation and in areas where it is hot most days of the year. Reflective glass (mirror)Reflective glass (mirror)
  13. 13. Usage of Light Glazing and Vision GlazingUsage of Light Glazing and Vision Glazing The double glazed glass will just allow the diffused sunlight to pass through and will radiate the solar radiation back. It is located in the western direction because the suns rays is highly radiant when it is setting.
  14. 14.  This consists of two sheets of glass with space in between, sometimes filled with air or other gases, or vacuum.  Variations in thickness have a certain effect, up to a certain limit, on the percentage of radiation allowed to penetrate and on thermal conductance of the composition.  The main advantage of this type of cross- section is its ability to reduce heat transfer from one pane to the other, both by conduction and by radiation.

  19. 19. Wind SystemWind System Wind tower with evaporative cooling A combination of sensible cooling in the ground and evaporative cooling with the flow of air induced by the wind tower can be achieved by a configuration as shown. The heat loss from air results in a decreased air temperature, but no change in the water vapour content of the air.
  20. 20. The hot ambient air enters the tower through the openings in the tower and is cooled, when it comes in contact with the cool tower and thus becomes heavier and sinks down. When an inlet is provided to the rooms with an outlet on the other side, there is a draft of cool air. After a whole of heat exchange, the wind towers become warm in the evening. Daytime and night time operation of a Wind TowerDaytime and night time operation of a Wind Tower During night the reverse happens; due to warm surface of wind tower and drop in temperature of ambient air due to buoyancy effect, warm air rises upwards. As a result, cooler ambient air is sucked into the room through the window. As a bye-product of this process, wind tower loses the heat that was collected during the day time and it becomes ready for use in cold condition up to the morning.
  21. 21. Wind tower design with openings on all four sides Wind tower design with evaporatively cooled system Due to the unpredictable wind direction, opening on all four sides are provided with an additional affect due to wind pressure. The rate of heat transfer mainly depends on surface area with which, the air comes in contact. Here the surface area is increased by having vertical conduits, which gives less resistance to air flow. Further, the effectiveness is increased by having sprinklers to promote the evaporative cooling
  22. 22. Wind DeflectorsWind Deflectors Interior partitions are provided in the building for various purposes of privacy, which may not allow openings in the partition. In this region, due to the warm and humid climate ventilation becomes very essential, cross – ventilation becomes the major solution. This can be overcome by providing ridge ventilation or ventilating ducts or shafts for deeper rooms.
  23. 23. The effect of positioning the apertures at various heights above the floor influences the efficiency of the natural ventilation in a given space. Inlet higher than outlet. Good interaction of air layers. Current at body level. Pocket of warm , still air over the outlet. Inlet and outlet are high. Airflow only near ceiling. No air current at body level. Good for removing hot air for warm season. Layers of still air at low levels.
