Sva-GRIHA Rating for VASTUKAR Design Studio
“Vastukar” design studio at Nageswar Tangi, Bhubaneswar, has been declared as the first 5-star rated green building in Odisha by GRIHA Council, the GRIHA’s highest level of recognition. The owner & architect of this building, Prof. S. S. Ray, Director, School of Architecture & Planning, received this prestigious award from the Dr. Krishan Kumar, Vice Chairman, BDA-cum-Commissioner, BMC on 20th July’16 on the gracious occasion of ‘One day Awareness program on Green building – The GRIHA way’ at Conference hall, KIIT University. The program was organized By GRIHA council in association with Bhubaneswar Development Authority (BDA) and Kalinga Institute of Industrial Technology (KIIT) University.
The Vastukar office building with a total built up area of 400mt2 and the building footprint covers 48% of the plot area, could score 47 out of 50 (94%) under the Sva-GRIHA Rating. The green building concept and technologies adopted in the building design and construction process to reduce the negative impact on its surrounding environment are – (1) The shaded and soft paved area is more than 90% of the total hard paved area of the site and Plantation of native grass and vegetation to preserve & protect nature, (2) Adoption of solar passive building design features (appropriate orientation, optimum shading devices, , green roof and green wall) and Active cooling systems (Down draft evaporative cooling & Ventilators) to ensure thermal comfort and reduce the overall energy consumption, (3) Energy efficient glazing & limited window area to reduce the incident heat gain up to 70% and allows adequate glare free natural light inside the living spaces up to 90%, (4) Energy efficient lighting fixtures and lamps (LEDs & CFLs) installed in the building to reduce the LPD level up to 2.19, (5) Installation of all BEE 5 star rated ACs and Fans, (6) Installation of 0.25KW solar photo voltaic based standalone garden lighting system & 1.5 KWP Roof Top Solar Photo Voltaic system to generate electricity, (7) Use of low-flow fixtures and faucets and Rain water harvesting system reduces the building water demand up to 50%, (8) Use of ACC (Autoclaved aerated concrete) blocks , PPC (Portland Pozzolana Cement), low-VOC and lead free paint and Use of locally available interior building material (sand stones, laterite stone & waste wood)reduces the overall embodied energy of the building at the same time adds to the thermal comfort of the building, (9) Solid waste management (waste segregation & resource recovery) and (10) Green life style (per capita floor area, unit travel time, use of herbal cleaning products, spreading awareness in green building etc.) also adds to the score of green building rating of this project.
