CONCLUSION AND SUGGESTIONS

OBJECTIVE AND

METHODOLOGY

To understand the need of building energy rating

systems in India

To study various types of building energy rating

systems available in India

To study various parameters of building energy

rating assessment

To carry out energy rating assessment of NICMAR

Pune campus

Methodology adopted for this work is literature

review and case study analysis

LITERATURE REVIEW

Main purpose is to find out the relevant information

about building energy rating systems in India

Literatures were grouped under three aspects

1. Sustainable Building Construction

2. Parameters of Building Energy Assessment

3. Building Construction Energy Rating Policy in India

It helped us to understand what is sustainable

building construction and its importance for India

We found the different advantages of sustainable

construction over conventional construction

LITERATURE REVIEW

Some literature has discussed about building energy

rating assessment and its parameters.

We found advantages of building energy

assessment in order to improve energy performance

of building

After study we came to know about different

policies of building energy rating in India

We came to know about different initiatives taken

by Government of India to implement these policies

Various energy rating agencies in India are providing

guidelines for energy rating of all types of building

construction

These are GRIHA, IGBC and BEE

CASE STUDY

Energy rating of NICMAR, Pune campus with respect

to energy rating systems available in India

Building type: Institutional building

Building area: 2,62,767 sq.ft.

Climate zone: Hot and dry

Energy rating is done with reference to

GRIHA

LEED India NC

Energy rating cannot be done with BEE as it is limited

to office buildings and commercial spaces

CASE STUDY

Methodology adopted for energy rating of NICMAR

Pune campus consists of main 3 steps

Data collection

Data analysis

Result generation and conclusion

CASE STUDY-Data

Collection

Data about NICMAR campus was collected by

study of official documents like architecture

drawings, electrical drawings, electricity bill etc.

Other information was collected by site visit to

various areas of campus

Data about energy rating systems and parameters

was collected by literature review

All other information like energy assessment

procedure and points allocation was obtained by

official websites of these energy rating schemes

CASE STUDY- LIMITATIONS

We found limitations to data collection to following

areas

Quality certificate of construction materials

Whether local construction material used

Data about site condition during construction

Air and water quality during construction

Details of quality of workmanship during construction

We have done necessary assumptions as required

CASE STUDY-Data Analysis

Required data was collected as per provision of

rating systems

The data was then analyzed as per the procedure

given in energy rating systems

We have followed guidelines given by GRIHA and

LEED India NC

We have compared the campus details with the

standards provided by above mentioned rating

systems

Necessary assumptions were made wherever

required

Sustainable features of

NICMAR Pune campus

Use of composite building envelope

Use of open grid pavement

Reduction of hard paving

Use of solar water heating system

Waste water treatment plant

Sustainable features need

to be adopted

Innovative waste water technologies

Use of high efficiency irrigation technology

Use of onsite renewable energy technologies like

solar lighting

Effective solid waste management systems

Reduce water use through automatic flushing, low

flush fixtures and other similar tools

Use of BEE rated equipments for energy use

reduction

Adoption of rain water harvesting systems

CONCLUSION

Sustainable building construction is need of

developing countries like India.

Energy rating assessment is perfect tool to check

performance of sustainability of a building

In India GRIHA, IGBC and BEE are prime three energy

rating tools available for building energy assessment

All these systems mainly assess building parameters

like water efficiency, energy efficiency, waste

management, site sustainability and safety-health

aspect.

Building energy rating promotes energy saving and

reduction in building waste

SUGGESTIONS

Energy rating assessment should be based on actual

performance of a building.

A periodic energy rating of buildings should be

made mandatory

In Indian context solar energy utilization should be

given high priority while checking building energy

performance.

All building documents should be properly

maintained by owner so as to facilitate energy

assessment

Government initiative is required to promote

awareness about building energy rating
