Green Grandeur
01 Feb 2019
Jade Vedant in Mumbai focussed on using smart materials and ensuring optimum daylight, leading the project to achieve the LEED Platinum rating by IGBC.
The vision for the IGBC Platinum-certified building Jade Vedant, a redevelopment project in Mumbai, was to create well-defined spaces for tenants and buyers. Designed in line with Mumbai façade norms while adopting contextual elements, the façade has been endowed
with a contemporary identity.
Sachin Goregaoker, Principal Architect and Partner, GA design, and Umang Kuwadia, Joint Managing Director, Happy Home Projects, share more on the measures taken to increase the green efficiency of the building that made it achieve the LEED Platinum rating by IGBC.
The grand design
The building has a grand entrance lobby with a wooden ceiling and a refreshing backdrop of green wall panels. The waiting area inside the building has a glass wall on two sides covered with bamboo plants. Internally, the compound wall has green panel inserts and the driveway connects to the car lift drop off.
An attractive feature of the car lift podium is the entire wall clad with tan brown granite with a geometric pattern formed with alternating leather-finished and polished granite. The bottom of all chajjas have been finished with wood-finished texture paint. Ducts on the side walls have been covered with powder-coated aluminium screens that display triangular patterns created by laser-cut perforations. The walls of the building have been treated with texture paint with a granite finish, giving it a rustic effect.
The orientation
A sun path design has been carried out and the orientation of the building is such that the living room faces the south side and the bedroom the north. The terrace has been beautifully landscaped and well-lit. The landscape garden on the ground and terrace with plants provide for oxygen emission.
All open spaces around the structure are covered with potted plants.
The project has made use of fully weather-resistant clear glass, which transmits more natural light inside the rooms. To ensure the building receives optimum natural light, sliding 8-ft-high windows have been provided, with a 66 per cent opening provided with clear glass. Also, the windows open 75 per cent, which helps keep the rooms inside well-ventilated.
Ductile design has been used to sustain seismic shocks. Dry cladding is preferred for the façade detailing.
Efficient energy savings
Solar panels of 6 kw capacity have been provided to reduce energy consumption. The project also uses low-voltage high luminous LED lamps. Along with five-star-rated HVAC systems, latex-based exterior paint of 3 mm thickness has been used, which reduces the heat load on the walls.
High on materials
To increase the green efficiency of the building during construction, AAC blocks, which have good thermal insulation property, have been used. The project also opted to use river sand as against crushed sand. Portland Pozzolana Cement (PPC), in which the heat evolution is lower compared to ordinary portland cement (OPC), has been used.
For the door frames, recycled BTC wood has been used, obtained from old demolished dwellings. The terrace tiles used have a high reflective index, owing to which light is reflected and heat gain is lower. The project has also made use of PVC drainpipes instead of asbestos pipes, which are carcinogenic.
Effective water and waste plan
The project uses aerated faucets and fittings to control the use of water. Rainwater harvesting has been installed with dual-operated flush tanks instead of flush valves. Overall, the reduction in water consumption is about 25 per cent. Further, an organic waste convertor has been provided to convert household waste to manure, which is used for gardening.
The cost of construction of the building, including its green features, is Rs 200 million.
Green grandeur, in its true sense!
