ESTIMATING PROJECT COST OF ENERGY COMPLIANCE BUILDING B. SANTOSH1, P. NAVEEN KUMAR2
--------------------------------------------------------------------------------***-----------------------------------------------------------------------------ABSTRACT: India is experiencing an unprecedented Several barriers slow down the process. First, stakeholders, construction boom. The country doubled its floor space such as architects, developers, and state and local between 2001 and 2005 and is expected to add 35 billion m2 governments, lack awareness of building energy efficiency and do not have enough capacity and resources to of new buildings by 2050 (Shnapp and Laustsen, 2013). implement ECBC. Second, most jurisdictions have not yet Buildings account for 35% of total final energy consumption established effective legal mechanisms for implementing in India today, and building energy use is growing at 8% ECBC; specifically, ECBC is not included in local building byannually. Studies have shown that carbon policies will have laws in most jurisdictions or incorporated into the building little effect on reducing building energy demand. permitting process. Third, there is not a systematic approach to measuring and verifying compliance and energy savings, Chaturvedi et al. (2014) predicted that, if there are no and thus the market does not have enough confidence in specific sectoral policies to curb building energy use, the ECBC. final energy demand of the Indian building sector will grow over five times by the end of this century, driven by rapid 1. INTRODUCTION income and population growth. Building construction is a combination of a designer’s skill The growing energy demand in buildings is accompanied by and the owner’s imagination. All building projects include a transition from traditional biomass to commercial fuels, some elements in common such as design, finance, particularly an increase in electricity use. This also leads to a estimation, and legal consideration. Consumption of rapid increase in carbon emissions and aggravates power energy can be reduced by changing the building envelope shortages in India. mechanism and proper selection of the comfort system. Growth in building energy use poses a challenge for the Indian government. To curb energy consumption in buildings, the Indian government issued the Energy Conservation Building Code (ECBC) in 2007, which applies to commercial buildings with a connected load of 100 kW or 120kVA.
Energy compliance building is the practice of constructing and modifying structures to be environmentally responsible, sustainable, and resource-efficient throughout their life cycle. Building and construction activities worldwide consume 3 billion tons of raw materials each year and represent 40 percent of total global use. It is broadly estimated that buildings worldwide consume about 40 percent of the planet’s materials resources and 30 percent of its energy and generates between 10 and 40 percent of the solid waste streams in most countries.
Previous studies estimated that the implementation of ECBC could help save 25-40% of energy, compared to reference buildings without such energy-efficiency measures. However, the impact of ECBC depends on the effectiveness of its enforcement and compliance.
The strong impact that buildings have on the quality of the environment, resource use, human health, and global economy is one of the main drivers that helped the concept of sustainable construction become more and more popular during the last decade.
Currently, the majority of buildings in India are not ECBCcompliant. The United Nations Development Programme projected that code compliance in India would reach 35% by 2015 and 64% by 2017. Whether the projected targets can be achieved depends on how the code enforcement system is designed and implemented.
A building envelope is what separates the indoor and outdoor environments of a building. It is the key factor that determines the quality and controls the indoor conditions irrespective of transient outdoor conditions. Various components such as walls, fenestration, roof, foundation, thermal insulation, thermal mass, external shading devices, etc. make up this important part of any building.
Although the development of ECBC lies in the hands of the national government – the Bureau of Energy Efficiency under the Ministry of Power, the adoption and implementation of ECBC largely relies on state and local governments. Six years after ECBC’s enactment, only two states and one territory out of 35 Indian states and union territories formally adopted ECBC and six additional states are in the legislative process of approving ECBC (BEE, 2013).
