LOCATION Nagercoil ("Temple of the Nāgas", Nagaraja- Jain Temple) is a city and administrative headquarters of Kanyakumari District in Tamil Nadu, India. Situated close to the tip of the Indian peninsula, it lies on an undulating terrain between the Western Ghats and the Arabian Sea. Nagercoil Corporation is the 12th biggest city of Tamil Nadu. Nagercoil derives from the Tamil expression Nagaraja koyil, meaning "temple of Nagas” Known as the Granar y of Travancore, Nagercoil not only served as the food basket of Kerala, but was also one among the important spice-trading centers in the kingdom of Travancore from the 14th century onward, and maintained a trade network with Arab merchants from the pre-Islamic era. Various Tamil and Kerala kings fought over this rich agricultural land, which boasted six rivers. Various historians cite that the land's climate and diverse, luxuriant vegetation had no comparison anywhere else in Tamil Nadu.

CLIMATE Nagercoil is an average of 29m above sea level. Nagercoil's climate is classified as Tropical. This climate is considered to be Aw according to the Köppen-Geiger climate classification. Tropical Wet and Dry
climate The temperature here averages 26.6 °C.
High Temperatures have to be reduced with cooling techniques. Hottest Months correspond with depression in Courtallam & Keeriparai.
Wind Direction is from North East, West & South West
Highest Windspeed can help in pushing out humidity
July & August have predominant winds from the West
Moisture content has to be reduces with the help of Ventilation
In a year, the rainfall is 985 mm. At an average temperature of 28.1 °C, April is the hottest month of the year. November has the lowest average temperature of the year. It is 25.6 °C. In Nagercoil, the month with the most daily hours of sunshine is March with an average of 9.8 hours of sunshine.
August & September have highest Wind Speeds from the South West
September & October have Winds from North West & South West
WIND
INFERENCES The West South Western Direction receives highest wind speed for the longest period. This happens predominantly in June & July Month. The Built environment has to be designed to reduce humidity by ventilating all the spaces and facilitating natural ventilation. Roof Spaces have to be vented on the top of walls to ensure convective cooling happens by pushing out hot air. Developing a long, thin floor plan with as many rooms as possible having windows or openings on at least two walls to achieve maximum cross-ventilation
Providing covered external living areas that are positioned to catch the prevailing breezes in both the wet and dry seasons Choosing windows that catch the breeze and can be left open in wet conditions, such as louvres, casements or awning windows Elongating the built up environment in a line across the prevailing wind direction gives low resistance to air movement and is therefore the ideal solution

DAYLIGHT
INFERENCES TheThe main goal of daylight is to bring in light deeper into the building in order to raise the illumination level and to reduce the illumination gradient across the room. The second goal deals with the reduction of direct glare of unprotected horizontal and vertical openings The third goal is to have a control over the brightness ratio, especially caused
by direct sunlight on or near the working plane. The fourth goal aims to prevent or minimize veiling reflections from skylights and high windows. Sunniest months during winter and overcast and partly clouded months dominate the year. North – south orientation favours the blocking up of the direct solar radiation, while providing natural light on the North Side with lesser solar heat gain.

TEMPERATURE
INFERENCES Hottest months are March and April. Design has to be optimised to reduce sola heat gain during those months while also reducing the humidity. Fully shading the eastern and western walls with battens, screens, shade cloth, awnings or spaced trees (dense planting will block breezes) Using lighter, more reflective colours on roofs and walls The openings should be large enough and fully operable, equipped with flexible louvers (protection from driving rain) allowing appropriate regulation of ventilation.
Due to the characters of solar radiation, shading devices are demanded. Creating landscape around the building or growing of green cover over the roof and wall (acts as a second skin), can improve the indoor climate. They reduce the sun glare, reduces noise and dust by sound absorption and by filtering air.
RAINFALL
INFERENCES External public spaces are to be covered and protected for sun and rain, provided they have a proper cross-ventilation. The openings should be large enough and fully operable, equipped with flexible louvers (protection from driving rain) allowing appropriate regulation of ventilation. To shelter the spaces from sun and rain and to have a control over the air flow, venetian blinds and louvers can be installed
Roofing systems to allow proper drainage of water. Storm Water collection system to help bring water from all sources to be brought to Rain Water Harvesting System. BioSwales to be designed along the site to help in optimising the landscape watering through natural means.
