Abstract
The ideology of ensuring energy-efficient design and construction of buildings by providing minimum requirements is the core objective of this work. Energy audit was conducted to improve the design of the building with incremental requirements to further enhance the energy efficiency. The Energy Conservation Building Code (ECBC) has been modified extensively over the years, starting from its initial deployment in the year 2011 to its latest modifications in the year 2019. The energy conservation standards in ECBC apply to building envelope, heating ventilation, air conditioning, lighting, service water heating, and electric power distribution. It should also be ensured that all-electric systems, transformers, energy-efficient motors, and diesel generators must meet the regulated set of mandatory requirements. From among the various software types that have been approved for ECBC design and application, this study has employed Energy Plus software to simulate the design based on the given input and the selected location. The location that has been chosen for this study was Bhubaneshwar, India. All necessary details ranging from latitude, longitude, weather, time zone, elevation, building area, lighting, heating, cooling, and much more have been covered in the simulation. Utilizing ECBC regulated standards for an energy-efficient building design has resulted in an increase in the energy savings by 27.4%, and thus, the building qualifies to be regarded as an ECBC compliant building.
Highlights
In India, the increased level of energy consumption has led to awareness regarding energy conservation among the public at a national level. e energy conservation bill along with the energy conservation Act was passed in the year 2001 and was later amended in 2010. e energy management center was reestablished and renamed as Bureau of Energy Efficiency (BEE) in the year 2002 [1]
E energy code established by the European commission known as the Energy Performance of Buildings Directive (EPBD) emphasizes that new buildings must be zero energy buildings by the year 2020 [3]. e acceptable indoor conditions in a building are being suggested by national and Advances in Civil Engineering international Indoor Environmental Quality (IEQ)
A critical review that provides comparisons of the requirements for environmental conditions by taking into consideration international standards such as international organization for standardization (ISO), American Society of Heating, Refrigerating and Air conditioning Engineers (ASHRAE), and national standards of countries like India and China can be founded [4]. is article critically reviews the standards for thermal comfort, with the main focus being on the quality of indoor air
Summary
In India, the increased level of energy consumption has led to awareness regarding energy conservation among the public at a national level. e energy conservation bill along with the energy conservation Act was passed in the year 2001 and was later amended in 2010. e energy management center was reestablished and renamed as Bureau of Energy Efficiency (BEE) in the year 2002 [1]. Further in 2007, the BEE launched the Energy Conservation Building Code (ECBC) to set up the minimum requirements for the construction of buildings to attain energy efficiency by properly following the design specifications. E objective of this work is to conduct an energy audit in a commercial building and to propose new load equipment and structural modifications in the building for energy saving and to make the building ECBC compliant. For this purpose, a commercial building was chosen in the city of Bhubaneshwar, India, and an energy audit was performed. Much tighter than those that have a higher air leakage rating
