SITE ANALYSISThe climate of New Delhi is a monsoon-influenced humid subtropical climate (Köppen climate classifica-tion Cwa) with high variation between summer and winter temperatures and precipitation. The tem-perature varies from 40 degrees Celsius in summers to around 0 degrees Celsius in winters. New Delhi’s version of a humid subtropical climate is noticeably different from many other cities with this climate clas-sification in that it features long and very hot summers, relatively dry cool winters, and monsoon and dust storms. Summers are long, from early April to October, with the monsoon season in between. Winter starts in November and peaks in January. The annual mean temperature is 25 °C (77 °F); monthly mean temperatures range from 14 °C to 33 °C (58 °F to 92 °F). The average annual rainfall is approximately 714 mm (28.1 inches), most of which is during the monsoons in July and August.Source: www.en.wikipedia.org

FACTS:

- Located in the center of new Delhi, the site is sur-rounded by high rises. It is close to Onnaught Place (officially Rajeev Chowk), which is one of the largest financial, commercial and business centers in Delhi. - The site has a triangle shape.- According to my classmate, Viraat Kumar, New Delhi has a composite climate: Summers are at its peak in May, as high as 45 °C. Heavy rains or monsoons in August. Presence of humidity in September. Winters are cold as low as 2 to 10 °C. No really windy, except monsoon season. Calm wind most of the year. Extreme change of tempreatures.- According to Google Earth, there are no places related to sports activities around the site.- The site dimensions are: 122 mt x 84 mt x 120 mt (5100 mt²).- A challenging project, where the building will be over-shadowed most of the year.

IDEA:

- Proposing a sports center, where people can go before, during or after work to relax, enjoy and work out.- The building will operate 24 hrs. during the week and from 10 A.M. to 10 P.M. during weekends.- The design tends to apply all the techniques and process learnt during this phase.- The New Delhi Sports Center will have saunas, pools, gym, soccer, basketball, tennis, and volleyball fields, and a cricket practice pitch (cricket is the most popu-lar sports in India).- Also, it will be a place to relax and learn from yoga, dances, martial arts, and other activities related to sports.- It will host corporal/grouped competitions or cham-pionships such as in volleyball, soccer, etc.

INITIAL DESIGN:

- The building will be 8 storey high.- It will follow the triangular shape of the site, and will be directed towards the southwest direction.- Although it will be shaded most of the year by the buildings surrounding it, the building tends to per-form well for its function, in terms of ventilation.- Large operable windows will be facing southwest, few and smaller operable windows will be facing northeast for natural cross ventilation. - Large windows will let natural indirect light pass through it.- It will have 2 atriums to let natural light come into the building.- It will have open floor plans to maximize spaces for different administrative, and sports activities.

Because of its location and activity, the project tends to perform well under the given conditions.

A test performing its shaded areas and percentages through the year give us the result that the building will be covered by its neighbor buildings most of the year. This condition will be a favorable condition for its occupants who will be exercising most of the time, and therefore feel cool. A wind analysis also was performed, with and without the building. De-pending of the year, and wind conditions there will be a small turbulence - cell pressure in one of the high-rise’s top, north of the building. Notice that wind speed does not change much all over the year, and that it remains calm with exception of the monsoom season.

Two initial skylights were proposed in the building to provided indirect natural lighting. The skylight will remain but the openings will be 25% big-ger than initially designed.

Three different tests were performed. For all of the tests, materials were changed to analize its insulation properties, and different performances. In the last test, additional and bigger openings were proposed in the north west area of the building.
