Energy Efficiency in Residential Building (EERB)

Project description

Title: Energy Efficiency in Residential Building (EERB)
Commissioned by: German Federal Ministry for Economic Cooperation and Development (BMZ)
Country: India
Lead executing agency: Ministry of Power (MoP), Bureau of Energy Efficiency (BEE)
Overall term: 2016 to 2020

Context

The majority of ancient India shows the preservation and sustenance of the environment in its monuments. During earlier times, sustainability and sustainable buildings were the way of life in India. These buildings not only provided comfort to the occupants, but also required no external intervention, which in modern times have become quite necessary. 

Many ancient monuments like Taj Mahal, Hawa Mahal, Forts in Mandu, Forts and Havelies in Northern India as well as the Kanheri Caves are classic examples of sustainable buildings with natural ventilation, elaborate rainwater harvesting techniques, evaporative cooling and central court yard for daylight. For instance, the first Kanheri Caves were carved during the 3rd century B.C., complete with natural lighting and cooling. However, recently the way of building houses in India has changed dramatically.

Rapid urbanisation is creating an unprecedented demand for the construction of buildings, which already account for more than 30 per cent of India’s total electricity consumption. In line with expanding development, the country’s building sector is expected to increase five-fold from 2015 to 2050. Projections show that electricity consumption in residential buildings is expected to increase sevenfold during the period from 2012 to 2032. 
The residential sector will become the largest consumer of electricity in the country with a 36.5 per cent share of the total electricity consumed in 2032. India is at a unique crossroad where two-thirds of the commercial and high-rise residential structures that will exist in 2030 are yet to be built. Thus, implementing energy efficiency in buildings that are being constructed in the next ten years presents a considerable opportunity to lock in energy and cost savings for the next several decades.

Objective

The Project practices energy efficiency through high technology innovations and the use of appropriate modern products, materials and designs, leading to sustainability and conservation of energy consumption.

Approach

The Federal Republic of Germany and the Government of the Republic of India have, under the Indo-German Technical Cooperation, agreed to jointly promote the “Indo-German Energy Programme” (IGEN) with the aim to foster energy efficiency and energy conservation in consumption in order to use energy more efficiently and in turn improve the environment and climate protection. The programme aims at supporting the Bureau of Energy Efficiency (BEE) for the development of an Energy Conservation Building Code for Multi-Storey Residential Buildings (ECBC-R) and thereafter supporting the implementation in selected states and municipalities through a mix of bottom-up and top-down approaches. To further complement and enhance penetration of energy efficiency within the residential buildings sector, GIZ has supported Government of India for development of labeling mechanism for residential buildings. These energy labels will help consumers to make efficient decisions through the provision of direct, reliable and costless information. The estimated energy saving potential through the labelling programme is around 388 Billion Units by the year 2030 resulting in a reduction of carbon emission by 3 million tonnes.

They are a key instrument in creating transparency over the energy performance of a home and is an effective device that is taken into consideration for home prices. During the assignment, capabilities have to be imparted to the stakeholders so that the code shall easily become implementable. Overall, the development of the ECBC-R and its subsequent application through a labeling programme will lead to a win-win situation for developer and consumer in terms of reduced life cycle costs of buildings, where energy efficiency triggers the savings for both the parties while leading to climate change mitigation. Energy labels would effectively differentiate buildings in the marketplace. Labels provide information on the potential and actual energy use of buildings and will also be utilised as the base for further incentive programmes. The long-term goal of this labelling mechanism could be to act as mandatory information required in any real estate transaction or leasing.

A further positive aspect for the Indian construction industry and manufacturers of building materials will be the huge benefit from the need to use modern technologies and materials, supplemented with an appropriate blend of the emerging and sustainable technology innovations.

Results
