DESIGN JOURNEY A boy named kumar, who never got an opportunity to go to school visits the vocational school , Foremost the eye catches the huge walls and enormous amount of greenery around once he gets closer to the building, he observes the huge central courtyard with quite a lot of people around curious to know more, he then moves forward classrooms all around, people doing different activities, beneath the wall, in the courtyard he sat down for relaxing slowly moving furture, he then notices open amphiteatre and auditorium, where one’s talent is showcased Amazed by everything on campus, he wishes to have a great learning experience too.

S I T E , C L I M A T E A N A LY S I S & P R O G R A M BRIEF A vocational training institute was chosen for this area to provide job training for students in the location. Students from many of the high schools in the surrounding area can opt for this institute to obtain better job opportunities. As an added benefit, this institute will alternatively function as a night school from 6:30pm to 10pm.

AIM The aim is to design and construct a school in such a way that it could accomodate users without consuming too much of energy and create negative impact on environment.

To achieve this we took the form of the building, its orientation, materials used and passive strategies into consideration

PSYCHROMETRIC CHART

From the psycrometric chart we get that we can achieve comfort by adding respective stratergies

RADIATION ROSE DIAGRAM

The rose diagarams help in determining the orientaion of the building

Observation: The hottest March, April and May. Inference: Insulation to be provided also sunshading techniques to be mplemented

Observation: Hottest months are March, April and May. Inference: The shorter side must be oriented in east-west direction and shading to be provided ENVIRONMEN TAL SHREYA PAI

SHADING

ASPECT RATIO

Inference Since the aspect ratio is 1:2 is lesser than 1:1, it is most prefered one.

Inference December to June months are more exposed to sun but June to December is comparatively comfortable.

Shading is required during the months of March, April, and may.

VENTILATION

WINDOW TO WALL RATIO

Inference Cross ventilation, wind catchers, stack effect, building should be tilted by 45 degree so that it catches more wind Helps to reduce the heat trapping. Cross ventilation reduces the humidity inside the room..

Inference The above table gives WWR for each facade which is derived from aspect ratio and orientation taken

ORIENTATION

WINTER SUN -Sun path at a low angle south to E-W axis - Solar radiation will penetrate south facing facades at a low angle during winter

SUMMER SUN -Sun path at a high angle north to E-W axis - glare free daylight is most easily available on north facade as minimal solar radiation will fall at high angle

East and west facades continue to recieve uniform strong radiation at a low angle throughout the year

ZONING & MASSING Zoning: The blocks area arranged in a way where there is one central space so that the accessibility to all the spaces are made easier. There is visual connection aswell. The placements of the blocks are done in such a way that the spaces are divided into public, semi public and semi private and all these spaces have direct access to green space.

Earth air tunnel or earth air heat exchanger is a pre-cooling or pre-heating system which consists of a pipe or network of pipes buried at reasonable depth below the ground surface. It either cools the air by rejecting heat to the ground or heats the air absorbing heat from the ground.

The exhibition space is semi indoor and outdoor, indoor exhibition area showcases the work and projects of students.

Library + reading room will have huge book shelves and seating space to read Open theatre has seating space and trees all around

The double heighted space in the design promets visual connection and interaction between the students.

Thick foliage trees in the periphery of the site acts as a natural sound proofing and seating spaces are also provided.

The space in the center of vocational school acts as a courtyard, helps in flow of cool air from ground and also promote interaction between the students, teachers and other staffs.

VO C AT I O N A L SCHOOL STRATEGIES TO REDUCE WATER CONSUMPTION 1. LOW FLUSH TOILETS, LOW-FLOW FAUCETS A low-flush or low-flow toilet is a flush toilet that is adapted in order to use significantly less water than a full-flush toilet. Low-flush toilets reduce the water consumption, The term “low flow” refers to fixtures that use a lesser amount of water to accomplish everyday activities, such as showering, washing your hands, or flushing the toilet. In some cases, low-flow fixtures can reduce water usage by as much as 60 percent over standard fixtures.

Working Principle - Human excreta is flushed away by a minimised amount of water.

Main strength - Comfortable and hygienic for the user. Saves large amounts of water in comparison with common flush-toilets.

2. GREY WATER TREATMENT Grey water can be defined as any domestic wastewater produced, excluding sewage. With proper treatment greywater can be put to good use. These uses include water for laundry and toilet flushing, and also irrigation of plants. Treated greywater can be used to irrigate both food and non food producing plants. The nutrients in the greywater (such as phosphorus and nitrogen) provide an excellent food source for these plants.

Major benefits of greywater use are: -Reducing the need for fresh water. Saving on fresh water use can significantly reduce household water bills -Groundwater recharge and reclamation of nutrients.

3. RAIN WATER HARVESTING SYSTEM / INSTALL RAIN BARRELS TO COLLECT RAINWATER Rainwater harvesting is collecting the run-off from a structure or other impervious surface in order to store it for later use. Traditionally, this involves harvesting the rain from a roof. The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel.

Rainwater harvesting systems consists of the following components: Catchment- Used to collect and store the captured Rainwater.

Conveyance system – It is used to transport the harvested water from the catchment to the recharge zone.
