Nagpur Metro Rail Corporation Limited (NMRCL) is installing energy efficient HVAC systems and LED lights and solar pipe based lighting in Nagpur metro stations. Sewage treatment plant is also planned to generate waster for non-drinking purposes.
The metro will also generate 65% of energy needed for its operations through solar power. NMRCL will install rooftop solar PV systems in two phases to meet this demand – 14 MW in phase I and 11 MW in phase II. Using the RESCO model, 70,000 square meters of roof space will be allotted to Mahagneco for installing solar PV panels. Metro stations have been designed to integrate roof top systems and ancillary equipment.
Indian Institute of Sciences (IISC) Bangalore has installed a 20 kW PV plant on the library building roof. The plant produces about 80 kWh of electricity daily. Since its installation in 2013, the systems has generated 85 MWh electricity, thereby averting 60 tonnes of carbon dioxide emissions. The team suggests that at current performance levels, investment in the PV system installed can be recovered in 4.5 years. IISC has also used the solar plant setup to study performance of PV technology in Bangalore across different seasons. Their study of the plant performance suggests a need to keep surface temperature of panels below 45 ºC as beyond this threshold the yield of the panels started dropping.
Chandigarh Renewal Energy and Science & Technology Promotion Society is proposing mandatory solar rooftop PV systems for all buildings. The notification will be issued after public consultation. Residential, commercial, educational, health and institutional buildings under the Municipal Corporation of Chandigarh will fall under the scope of this program. Notification will apply to residential buildings on plot sizes greater than 100 square yards and housing complexes on more than .2 hectare of land.
Delhi government has set a target of 1 GW of solar power generation daily through rooftop installations by 2020. This is to be increased to 2 GW by 2025. To achieve this target, the government has proposed 30% subsidy in capital investment and mandatory installation for all government and commercial buildings. The schemes offers home owners alternatives – they can either avail the subsidy for installing rooftop PV themselves or lease out roof space to firms in exchange for using electricity generated through the PV system. Owners will be able to sell surplus back to the utility. An incentive. An incentive of Rs. 2 will be provided per additional unit of electricity generated and sold to the utility. No approvals will be required for installation and panels will allowed to be mounted on frames to keep terrace space free for other activities like clotheslines, terrace gardens etc..
NZEBs can be possible and more economical in Delhi now!
KOCHI: India has the potential to achieve government’s ambitious plan to increase its solar power capacity target five-fold to 100GW by 2022, a top executive of Bosch Ltd has said. “India has the potential to achieve the government’s ambitious target of 100GW of solar power generation in the country by 2022 and Bosch is committed to be a part of this success story,” Steffen Berns, president of Bosch India and managing director Bosch Limited, said in a release.

TOKYO — Major homebuilders in Japan are hoping to sell many more net-zero energy houses, that is, homes whose efficient designs and solar panels mean they have a net energy consumption of zero. In some cases, they may even be net energy producers.
Misawa Homes plans to build zero-energy houses for sale on a large scale in fiscal 2017. The company has already introduced homes with high-performance fiberglass insulation and solar panels as standard features in relatively inexpensive houses targeting people in their 30s. Read more…
Mainstreaming NZEBs in India would require market transformation as well as policy interventions. There is a need for industry, building professionals, and policy makers to collaborate to catalyze, facilitate, and drive the large-scale adoption of NZEBs. While several green building projects are now imbibing , the integration of renewable energy in buildings is still in a nascent stage. There is a need for a concerted effort, proposed here in the form of an alliance to lead this goal of NZEB. The objective of the alliance is to accelerate market development of NZEBs in India, with a vision to facilitate design and construction of affordable NZEBs by 2030.
In late March, the Rocky Mountain Institute hosted the second annual eLab Accelerator. Described as a bootcamp for electricity innovation, the four-day intensive work session brought together 12 teams from across the country
