The main function of buildings is to provide a comfortable indoor environment and to protect mankind from the extremities of climates. A growing worldwide concern for the conservation of energy and depletion of natural resources leads to a renewed interest in those aspects of building design, which leads to comfort conditions in buildings with minimum use of conventional energy and depletion of natural resources. Global final energy consumption by buildings and their construction is 30% of overall energy consumption whereas total energy sector emissions is 27%. If buildings (new/renovation) designed on energy-efficient strategies, there is immense potential to reduce consumption and regenerate resources from waste and renewable sources.

The scope of these guidelines is to provide a framework to address the sustainability in the design of both new construction and renovation of the existing building. These guidelines discourse the methods to develop energy-efficient building by using energy efficiency standards as laid down in National Building Code of India 2016 Part 8 by the Bureau of Indian Standards (BIS) and the regulations given by PSPCL from time to time.

1. Use of sustainable building materials in the most possible efficient way.
2. Design of energy-efficient buildings to reduce the building’s carbon footprint.
3. Promote the use of energy-efficient gadgets as per Bureau of Indian Standards and the regulations
4. Use of renewable energy as far as possible
5. Adoption of various strategies to enhance energy efficiency of buildings

The Lovely Professional University follows 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. The Code mainly contains administrative regulations, development control rules and general building requirements; fire safety requirements; stipulation regarding materials, structural design and construction (including safety); building and plumbing services; approach to sustainability; and asset and facility management.

National Building Code of India has been provided guidance for making buildings, built environment energy-efficient and environmentally compatible, through the newly introduced and an updated chapter on sustainability, namely ‘Approach to Sustainability’. New chapters have been added on structural use of glass, information and communication enabled installations and solid waste management.

A few selected salient features for energy efficiency improvement in the revised National Building Code are;
5.1. New and alternative building materials, and technologies:
University shall use New and alternative building materials, and technologies for building construction such as reinforced masonry, corrugated iron, confined masonry building construction, cardboard, natural stone, and masonry wall construction using a rat-trap bond.
5.2. Efficient Lightning System:
University shall include modern lighting techniques such as LED and induction light and to reduce their energy consumption Lighting Control System, OFF-GRID lighting shall also be introduced.
5.3. Energy Efficient Air Conditioner:
Inclusion of new and energy-efficient options of air conditioning, heating and mechanical ventilation, such as variable refrigerant flow system, inverter technology, district cooling system, hybrid central plant using chilled beams, radiant floor components, and geothermal cooling and heating.
5.4. Envelope Load Optimization:
Thrust on envelope optimization using energy modelling, daylighting simulation, solar shade analysis and wind modelling software to optimize the air conditioning load.
5.5. Adaptive Thermal Comfort Conditions:
Air conditioning, heating, and ventilation (HVAC) provision considering adaptive thermal comfort conditions for energy efficiency. Solar Water Heating Systems shall be installed to meet hot water requirement in the hostels and residential buildings in the campus. Total electricity consumption load shall be met through renewable energy sources.
5.6. Architectural Sustainability:
Promoting sustainability in buildings and built environment in tandem with relevant sustainable development goals.

For establishing the sustainable development mechanism, the university is committed towards the improvement of energy efficiency in new building/renovations following the energy efficiency standards as laid down in National Building Code of India 2016 Part 8 by the Bureau of Indian Standards and the regulations given by PSPCL from time to time.
