Green building certification

GRIHA Certification: IREO Forest

Buildings represent a large fraction of global carbon emissions and energy consumption. In addition, shopping centres affect local communities in several ways. By integrating sustainability measures into our daily operations, we aim to do more than expected to achieve sustainable development. We have long promoted sustainable solutions through integrated energy planning. We have brought together the architects, building designers, and technology specialists to retrofit the existing buildings. Firstgreen has worked on some of the best projects of India such as LEED Platinum Volume project of DLF group which has been approved by USGBC as a part of country’s first LEED EBOM volume project. The DLF Emporio, DLF Mall of India , DLF Cyber Greens, DLF Plaza tower, Ericssion, DLF Square are some of our LEED Platinum rated buildings from USGBC. We have also registered the green building projects through GRIHA as well as IGBC.

IREO Forest is a commercial complex with about 335000 sqft built-up area. Ireo group appointed Firstgreen consulting for its green building certification from GRIHA.  The starting points of the planning for The Corridors are principles of sustainability and natural convenience. Its buildings have been constructed with materials which are durable and balanced enough to withstand the hot, dusty, infrequently wet environment of Haryana. Windows are crafted with glass material that does not require regular maintenance of cleaning them with precious water. Hence, it serves the dual purposes of saving cost and water.

Going green does not mean higher construction cost to the client, actually the cost of a green building is sometimes lower than the normal building. The buildings were designed with a favourable orientation so that heat gains are minimal, and cleverly for the climate, we need less cost on air conditioning. The building used local materials such as Kota stone, etc so that materials embodied energy can be reduced. 

We have also incorporated a 416kW solar PV system on the roof which will supply power to the common area lighting of the building. Rigorous 3D energy modelling was done by Firstgreen team to assess the suitable glass selection in the building. The lighting was done using the LEDs to keep the lighting power density below 0.5W/SQFT. There will also be a provision for cyclists and showers to encourage building users to cycle rather than use a vehicle, again in an effort to reduce the carbon footprint.

We are hoping that Ireo group will inspire the other developers to design their building in this way.
