Which city population data for 2019 is acceptable?

Cities can provide smart city proposal population data with the growth rate calculated for 2019. Cities providing the population data based on ULB estimates or ward wise estimates available from latest municipal elections is also acceptable.

What is the assessment period for Energy and Green Buildings indicators?

The assessment period for all the Energy and Green Buildings indicators is 2019-2020 Financial Year.

What is meant by alternative cleaner fuel sources?

Alternative fuels are derived from sources other than petroleum. Most are produced domestically, reducing our dependence on imported oil, and some are derived from renewable sources. Often, they produce less pollution than gasoline or diesel. Some well-known alternative fuels include biodiesel, bio-alcohol (methanol, ethanol, butane), refuse-derived fuel, chemically stored electricity (batteries and fuel cells), hydrogen, non-fossil methane, non-fossil natural gas, vegetable oil, propane and other biomass sources.

The intent of the indicator (as explained in the rationale) is to encourage lesser dependence on fossil fuels.

What is energy-efficient street lighting?

Energy-efficient technologies (example, LED) and design (example, better location to improve coverage/luminosity and reduce overall number of light points) can cut street lighting costs dramatically (often by 25-60%); these savings can eliminate or reduce the need for new generating plants and provide the capital for alternative energy solutions for populations in remote areas. These cost savings can also enable municipalities to expand street lighting to additional areas, increasing access to lighting in low-income and other under-served areas. Also, improvements in lighting quality and expansion in services can improve safety conditions for both vehicle traffic and pedestrians.

What is Green Building?

Green Building is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life-cycle, from siting to design, construction, operation, maintenance, renovation and deconstruction. This practise expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green Building is also known as a sustainable or high-performance building.

What is Pre-Certification?

There are various systems that provide pre-certification such as Energy Conservation Building Code (ECBC) and the Star Rating for Buildings, both by the Bureau of Energy Efficiency (BEE), Leadership in Energy & Environmental Design (LEED) of the Green Building Certification Inc. (GBCI); Green Rating for Integrated Habitat Assessment (GRIHA) of The Energy Research Institute (TERI), Green Building Rating System of the Indian Green Building Council (IGBC).

Projects can get pre-certified for a Green Building at the design stage. The documentation submitted for pre-certification must detail the project design features, which will be implemented. The rating awarded under pre-certification is based on the project design details that comply with the requirements of the rating system. The pre-certification rating awarded need not necessarily correspond to the final certification.

What is ECBC?

ECBC stands for “Energy Conservation and Building Code” developed by the Bureau of Energy Efficiency, Ministry of Power. ECBC provides standards for Building Envelope Walls (Walls, Roofs, Windows), Lighting (Indoor and Outdoor) Heating Ventilation and Air Conditioning (HVAC) System, Solar Hot Water Heating and Electrical Systems. The enforcement of the code lies with the state government.

What is meant by NBC compliance at the state level?

The National Building Code of India (NBC), a comprehensive building Code, is a national instrument providing guidelines for regulating the building construction activities across the country. It serves as a Model Code for adoption by all agencies involved in building construction works, be they Public Works Departments, other government construction departments, local bodies or private construction agencies. The Code mainly contains administrative regulations, development control rules and general building requirements; fire safety requirements; stipulations regarding materials, structural design and construction (including safety); building and plumbing services; approach to sustainability; and asset and facility management.

NBC at the state level means that the code is available only for compliance at state level and city has not incorporated the NBC code in its building regulations.

What level of Green Building certification will be accepted?

The first level of the rating system will be accepted for this assessment e.g. 1 star under BEE rating, ECBC, GRIHA or basic certified under LEED, IGBC.

What is Built-up Area (BUA)?

The Built-Up Area (BUA) is the total area being developed or constructed. It is the Gross Floor Area and any Service Area associated with the subject building or project, that is occupiable and covered by a structural roof and enclosed as per the local. (GDCRs)

What type of buildings is to be included to calculate the total built-up area in the cities?

Residential and commercial buildings will be considered for this assessment.
