VENTILATION Outdoor breezes create air movement through the interior by the push-pull effect of positive air pressure on the windward side and negative pressure(suction) on the leeward side. Good natural ventilation requires locating openings in the opposite pressure zones. Also, designers often choose to enhance natural ventilation using tall spaces called stacks in the buildings. With openings near the top of stacks, warm air can escape whereas cooler air enters the building from the openings near the ground. TO PROVIDE FRESH AIR TO THE OCCUPANTS HEATING AND AIR- CONDITIONING WHY VENTILATION?? AIR QUALITY TO DISTRIBUTE HEATING OR COOLING TO PROVIDE NATURAL PASSIVE COOLING TO DILUTE AND REMOVE POLLUTANTS RELATIONSHIP BETWEEN NATURAL VENTIALTION AND THERMAL COMFORT Thermal comfort is affected by air temperature and air movement. Ventilation obviously has an impact. If the external temperature is lower than the internal, then natural ventilation can be used for cooling if necessary. Another secondary cooling affect results from air movement. Even if the temperature of the incoming air is the same as that already inside it can feel cool because it is moving. Heat is lost from the body by the consequent evaporation of sweat on the skin. Designers can achieve cooling by utilizing this effect even when internal and ambient temperatures are similar.
PREVELANT WIND DIRECTION WHAT IS THE PREVELANT WIND DIRECTION IN DELHI? JANUARY FEBRUARY MARCH DELHI, India is in the area of high pressure. From December February, northerly, light winds carry dry, cool weather with little rain, making this time the driest of the year. However, from June to October, monsoon winds from the southern west are moist and rain-bearing. The prevailing wind pattern is very unusual because the winds switch directions. The weather becomes hotter and remains dry from march to may. Some years the rains are torrential, but when the monsoon fails, the rain is light or it varies from place to place.

NIGHT COOLING It is a very effective strategy during the summer months especially when the house has high thermal mass. High thermal mass components, such as the walls, the floor and the roof, can absorb large amounts of heat during summer. This mechanism keeps the house cool during a summer day. However, this amount of heat is released during summer nights. So, night ventilation can remove this heat and precool the house creating a lower temperature for the start of the next hot day. Practically for a homeowner, the answer is to open your windows at night and allow the building to properly cool, before closing the windows in the morning to allow the building fabric to take up the heat of the new day without heating the air in the home. So there are a few different methods of natural ventilation and when and where you can use them in your home. Taking advantage of this form of ventilation is going to save you money on air conditioning, reduce your energy use, and help keep you cool!
SINGLE-SIDED VENTILATION can be achieved be achieved in rooms that have a single window at just one wall. To use this to best effect, the width of the room should be equal or lower than 2 times the height of the room.(fig.1) STRATEGIES OF NATURAL VENTILATION CROSS VENTILATION can be easily used to each room that has two opposing windows. You can achieve more airflow and a cooler effect by opening both windows rather just one of them when the width of the room is higher than 2 and less than 5 times the height of the room.(fig.2) (Fig. 1) Single-Sided Ventilation STACK VENTILATION depends on the temperature difference within the space. The hot air is less dense than the cooler air so it has an upward route when indoor temperature is more than the outside air. So, if the house has roof windows or a chimney a good way to naturally ventilate the space is to open them rather than just opening the lower windows of the house during the hot days.(fig.3) (Fig. 2) Cross Ventilation (Fig. 3) Stack Ventilation
THE VENTILATION PROCESS Fig.1 and Fig.3 shows that there is no natural ventilation inside the building as all the windows are fixed. Fig2 and Fig4-the ground floor plan and the first floor plan respectively shows that if the windows are added and more windows are added to the building then how much it can receive the natural ventilation. (Fig. 1) Ground Floor Plan-Old Plan (Fig. 2) Ground floor plan(after refurbishment) (Fig. 3) First Floor Plan-Old Plan (Fig. 4) First Floor Plan-After refurbishment
THE VENTILATION PROCESS The natural ventilation system works well when there is cross ventilation in a space. So in order to provide a good ventilated space I have tried to give open-able windows on opposite walls. This will help the air to flow in and an outlet duct is being provided in the corridor which will help in outflow of the air. As the air will flow out and fresh air will start entering inside the room, this will help the air to keep moving. As the air enters inside the space it becomes hot and tends to rise due to the temperature difference in outside and inside area. Some air will flow out through windows and some that will rise up will move out through the outlet provided. The outlet duct on the top has exhaust system which suck all the hot air and let the cool air come inside the building.
WIND TOWER Cross ventilation is the best technique to keep the area or building ventilated. As the site is not naturally ventilated so I have tried to create a outlet duct that would suck the air, allowing it to move out of the building and providing space for fresh air to come in. this would help to move air quickly inside the building making the building naturally ventilated.

SUN MOVEMENT AND PENETRATION WHY IS IT HOT IN SUMMERS AND COLD IN WINTERS?? It is all about the tilt of the Earth s axis. Many people believe that the temperature changes because the earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January. During summer, the sun s rays hit at a steep angle. The light does not spread out as much, thus increasing the amount of energy hitting any given spot. Also, the long daylight hours allow Earth plenty of time to reach warm temperature.(fig. 1) During winters, the sun s rays hit the Earth at a shallow angle. These rays are more spread out, which minimize the amount of energy that hits any given spot. Also, the long nights and short days prevent the Earth from warming up. Thus, we have winter!(fig. 2) (Fig.1) Movement of sun in summers (Fig.2) Movement of sun in winters

SUN CHART This is the sun path movement from June 21 to December 23 that is the summer fall. This picture shows that people are comfortable when the temperature is above 20 C and below 27 C. So, this image shows that when the sun moves from east to west at different times of the day and in different months how people would react to in the atmosphere. The area marked with yellow shows the comfortable zone that is from mid September to December starting.

SUN MOVEMENT AND PENETRATION RULE OF THUMB FOR DAYLIGHTING The daylight penetration in a space varies linearly with window head height. (Fig.1 ) Limiting depth=2.5 * h window-head height (Fig. 1) Rule of thumb for Day lighting N NORTH ORIENTATION AND THE SUN PATH AND THE PENETRATION As the plan shows the building is facing towards north so the back side of the façade is facing south. And as the sun moves from east to west from the southern hemisphere this is how the sun will move in the and according to the rule of thumb for day lighting, the penetration in a space is 2.5times the window-head height. (Fig. 2) Sun penetration WEST EAST SOUTH

WATER MANAGEMENT This is showing the process where one can use the water by pumping it to the tank. The water that is being used for drinking and washing hands can be collected in a collection tank underground and from there it can be processed and all the soap that is being washed away while washing hands can be removed and it can be pumped back to the tank up from where it can be used in the water closets and the urinals.
