Online Solar PV Rooftop Calculator by MNRE

Ministry of New and Renewable Energy has launched an online PV system calculator for consumers interested in installing solar rooftop systems. SPIN will help in estimating potential PV capacity that can be installed, applicable tariff rates and electricity required by building owners. The tool can be used to determine PV system size and costs for commercial, residential, institutional and industrial sectors.

Nagpur Metro to go Green

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.

IISC, Bangalore shows the way to solar energy

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.

Rooftop solar PV will now be mandatory in Chandigarh

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.

Is Delhi going to be a solar metropolitan city ?

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!


Cochin Airport to be Powered by Solar

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.

For Japan homebuilders zero is magic number

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.

PACE-D TA Program to Launch a Net-Zero Energy Buildings Portal in July

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.

World’s tallest Passive House tower to be built in Roosevelt Island, New York

A 26- floor residential passive house building is currently under construction on New York City’s Roosevelt Island for Cornell Tech’s new campus. This new structureexpected to be completed in 2017- will surpass what is currently the world’s tallest passive house building. It has a height of 82 meters and covers an area of 25084 m2. The exterior walls are 35.6 cm thick prefabricated panels insulated with 27.9 cm of mineral wool and triple glazed windows (U-factor = 0.156). The panelised wall system was chosen both to speed up the construction and decrease the number of joints required to be carefully sealed. Heating and cooling will be provided by variable refrigerant flow air-source heat pumps while a centralised energy-recovery ventilator will provide fresh air to, and exhaust stale air from, each apartment.

Rocky Mountain Institute A small Iowa town embraces energy independence

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 — from New Mexico to Alaska and California to New Jersey — working on new business models, energy innovation districts and new customer solutions. Together with RMI facilitators, Reos Partners and a panel of expert faculty, they sped progress on their respective efforts. This is one of their stories. How does a single streetscape project
turn into a community-wide energy independence effort? Tiny Bloomfield, Iowa, discovered the answer with the help of RMI’s eLab Accelerator. A team from Bloomfield attended the 2015 Accelerator at Sundance Mountain Resort in Utah, and its story is a surprising one with big implications for small towns across America.
