SUSTAINABLE BUILDING DESIGN


This project attempts at creating a built environment, which is totally a climate responsive structure. The building form, construction materials etc are all in response to the climatic conditions of Bangalore.
This project is designed to house an office with nearly 75 workstations and a small guesthouse attached to it. The site is a long and narrow strip of land located at Domlur, about 3km from Bangalore Airport with access roads on East and North.
DESIGN RESPONSE:A cavity wall using Caddapah stone(locally available material)facing the drain with no openings for air inlet prevents the entry of foul smell from the drain to the interiors of the building. PASSIVE VENTILATION METHODS: The open nature of the built volume creates natural flow of air within the building. The inlet from the roof vents on the North being at a lower level, sucks in fresh cool air and the outlets towards the south roof expels the hot air. The cavity wall and the solar chim- neys on the south enhance the natural ventilation of the building. The earth is raised towards the south (earth berm) to reduce the conduction of heat.
DAY LIGHTING DESIGN: By creating Atrium spaces with skylights the building gets ample amount of daylight resulting in small dependency on artificial lighting during daytime.
RENEWABLE ENERGY SYSTEMS: A 5-KW peak solar photo voltaic system, integrated with the roof skylight caters to the water heating requirements of kitchen and guest rooms as well as produces electricity to support the few CFLs installed.
RAIN WATER HARVESTING: The runoff water from the rooftops and the paved areas gets collected at various levels in small open tanks on the terraces and finally in an underground tank (sump tank) below the garden area in the front yard. This collected rainwater is used to water the plants on the rooftops as well as in the front yard.
ROOF GARDEN:The ground cover, which is disturbed due to building of this structure, is replaced on rooftop, in the form of terrace garden, giving insulation to the building & reducing solar radiation. Thus the design addresses not only thermal comfort but also visual appeal and environmental issues. The five elements of nature, as described in Hindu mythology, have been well integrated in to the sys- tem of built form in this design.
AIR: Convection currents within the building through wind induced vents – use of Venturi effect
EARTH: Roof gardens and earth berms for insulation
SUN: Solar panels for water heating, electricity generation; creating stack effect through solar chim- neys for effective ventilation.
SKY: Day lighting thru skylights
WATER: Rain harvest of water to conserve; for humidification roof ponds and fountains.

SUSTAINABLE DESIGN COURSE FOR FUTURE ARCHITECTS
Students design passive architectural forms after learning the theoretical course in Architectural insti- tute of FESTU last five years. Modification the microclimatic conditions of open and closed space using previously architectural forms (Interaction of architectural and landscape forms with wind and sun).
One group of students (20-25 people) will be learning green design principles in practice during next three years.

GREEN DESIGN STEPS FROM SIMPLE FORMS TO DIPLOMA DROUGHT INCLUDE:
1. Direct gain of south facade only. First project with passive solar design – Settlement center (third year student projects, autumn). Passive solar design not compulsory, only for advanced students.
2.Simple architectural form with wind-break and solar heating possibility (A). Covers for kindergarten for 10-12 children (third year student projects, spring). Compulsory practice in framework of theoret- ical course.
3.Direct gain and natural ventilation of atrium space only. School for 250 pupils (four year student projects, autumn). Passive solar design not compulsory, only for advanced students.
4.Passive heating and cooling, hot water and space heating by solar water collectors; wind-break design of building and site (B). Low store dwelling or Single family house (four year student projects, spring). Compulsory use all methods of passive and active solar design. May be natural construc – tions and plasters.
5.Green design from passive and active solar heating to bionic exterior and interior imagine and
“green” graphic style of documents. Public building – urban complex (five year student projects, autumn – spring). Green design not compulsory, only for advanced students.
After learning all green stages, advanced students will be ready for “Green diploma projects” (C), and future Green practice. The main part of diploma project besides draughts is the essay about Sustainable design principles.
There are three “green” graduate groups for the last five years: 2001, 2003, 2005 (June) – almost 60
students. And one group of 20 students will be in future – 2007, June.
All projects design for local climatic conditions of south Primorye, Russian Far East
Winter: November – March, north-north-west wind 7-12 m/s, up to 15 – 18 m/s; temperature -12 -20
C in January ; November and March approximately – 8 +8 C; all season sunny weather. Cold sum- mer: April – June, south-east wind 5-7 m/s, up to 10 – 15 m/s; temperature +10 +16 C in June, up to
+20 +22 C some sunny days; humidity 100%, usually cloudy. Summer: July – August, south-east wind
5-10 m/s, up to 15 – 20 m/s; temperature +20 +25 C, humidity 100%, usually rainy. Deviation direction of wind by hills (50 -150 m, up to 200 meters) may be 45 degrees.
