The Kohli Residence, situated in Gurgaon, maintains a perfect blend of VastuShastra, passive architecture and Green lifestyle – a design brief set by the proud owners. The project was developed keeping the intention of liveability, modern vision, environmental consciousness and energy optimisation at the forefront. Green Building Consultancy Services – a distinguished segment of Godrej & Boyce – worked jointly with New-Delhi based architecture teamConfluence. Spread over 450sq-m with G + 2 facilities and a basement, this luxury haven with its effective sustainable measures has been certified Gold by the IGBC (Indian Green Building Council) – a success story that is worth imitating for other upcoming projects.
From the inception stage, the norms such as efficient site management were followed. Before construction could commence, effective erosion and sediment control (ESC) measures were implemented to eliminate pollutants from entering the outside environment and local water bodies. A waste yard was also constructed at site segregating steel, wood blocks, debris, cement bags, plastic cans and packing materials, etc. These waste materials were sold to recycler –preventing these materials from reaching the landfill.
Ventilation of fresh air for the entire habitable spaces is met through energy efficient Heat Recover Wheel – meeting all the requirements of Indoor Air Quality (IAQ), humidity control and energy saving. HRVs have multi-speed settings to deal with varying ventilation needs. Automatic controls are available as well to modulate the operation of the HRV based on time and indoor humidity level.
Water being the most precious resource, rainwater harvesting has been implemented; both roof and non-roof run-off is collected. Water conservation is also an important element of Green and sustainable design. Despite housing a family of five, the house uses 25% less water than the baseline prescribed by IGBC. This was made possible by incorporating modern water fixtures like dual-flush toilets and low-flow faucets. The project team also chose Renewable Energy Technology in the form of solar water heater to meet the requirement of hot water for bathrooms and kitchens.
LED lighting and automated lighting controls are the efficient energy features implemented in the villa.Because exterior lighting and utility lights are needed only when it is dark, timer controller fulfils the need efficiently. Motion sensors turn lights on automatically when someone enters a room, enhancing occupant comfort and saving energy by turning lights off soon after the last occupant has left the room. Green design parameters like efficient window wall ratio and maximised natural day lighting are implemented providing 95% of the regularly occupied spaces with natural day lighting. Ecotect2010 software is used for Daylight Analysis.
Household waste (post-occupancy)is being managed by segregating the waste at the kitchen level, i.e. dry & wet waste. Further, the waste is segregated into five categoriesviz.paper, organic, metal, plastic and e-waste for end-to-end disposal.The organic waste is converted into manure on site through organic waste convertor, which is utilised in the landscape areas within the premises.For a sustainable landscape, plants that grow well in local area were selected. These plants thrive based on the local condition whether it is available sun, rainfall or soil type. Native plants were planted on the ground and in the terrace landscape.
Implemented green features:
- Heat Reflective Roof Tiles having SRI value greater than 78
- Terrace Garden for Roofing insulation
- Highly Efficient Double Glazing Fenestration
- Natural Day lighting on 80% of the habitable spaces
- Water heating requirement through Solar
- Highly energy efficient VRF air conditioning system
- Fresh air ventilation through Heat Recovery wheel.
- Low VOC Paints for interior for best-suited occupant comfort
- Complete usage of FSC Certified Wood
- Waste disposal via Organic Composter
