Energy Efficiency, Energy Auditing, and Green Building
Energy efficiency is a way of managing and restraining the growth in energy consumption. Something is more energy efficient if it delivers more services for the same energy input, or the same services for less energy input. A green building minimizes the demand on fossil fuel based energy, maximizes the recycle, reuse, renewable energy, and energy efficient devices and appliances. The need to reduce energy consumption and increase use of renewable energy in buildings have been an important concern. Consequently energy conscious architecture has been promoted which includes the use of solar passive design concept, use of eco-friendly and less energy intensive building materials, integration of renewable energy and energy efficiency, water recycling etc. This was the origin of the green building concept.
The GOI launched the National Mission on Enhanced Energy Efficiency (NMEEE) in June 2010 with an outlay of INR 2.35 billion. The NMEEE is one of the eight key missions under the NAPCC. By 2105, the mission is expected to result in savings of nearly 23 million tons oil-equivalent of fuel in coal, gas and petroleum products (E&Y 2103). The key initiatives under the NMEEE include:
1. The Perform, Achieve and Trade (PAT) Scheme: a market based mechanism to enhance energy efficiency in large energy intensive industries. The designated entities are given energy intensity improvement targets. If the entities exceed this target, they are issued tradable energy saving certificates (ESCerts), which can be bought by other entities that are unable to meet their targets.
2. The Market Transformation for Energy Efficiency (MTEE): aims to promote and accelerate the shift toward energy efficient appliances in the designated sectors through various methods including mandatory energy efficiency labeling for equipment and appliances and by making them more affordable through clean development mechanism(CDM) financing.
3. The Energy-Efficiency financing platform: focuses on creating mechanisms to help finance demand side management (DSM) programs in all of the select sectors by capturing energy savings.
In August 2013, MNRE sanctioned the “Energy Efficient Solar/Green Buildings” scheme for implementation during 2013-14 and the rest of 12th Five Year Plan. The main objective of the scheme is to promote the wide spread construction of energy-efficient solar/green buildings in the country through a combination of financial and promotional initiatives. An amount of INR 100 million has been allocated for the implementation of the scheme.
Energy Auditing: Effective management of energy-consuming systems can lead to significant cost and energy savings as well as increased comfort, lower maintenance costs, and extended equipment life. The energy audit evaluates the efficiency of all building and process systems that use energy. The energy auditor starts at the utility meters, locating all energy sources coming into a facility. Auditing includes identification of energy streams for each fuel, quantifying those energy streams into discrete functions, evaluating the efficiency of each of those functions, and identifying energy and cost savings opportunities. Audit activities, in general order, include:
• Identify all energy systems
• Evaluate the condition of the systems
• Analyze the impact of improvements to those systems
• Write up an energy audit report
CRESD promotes energy efficiency policy, process and technology in buildings, appliances, transport and industry, as well as end-use applications. We identify the best-practices, highlighting the opportunities for energy efficiency improvements and policy approaches in each sector and promote awareness and capacity building on the same. We at CRESD also believe that effective energy management begins with an energy audit. The Energy auditors at CRESD conduct comprehensive, rigorous and meticulous energy audits.
