INTRODUCTION

• Energy audit and validation is 32nd griha criteria.

• Points: 0 (no points will be awarded for this criteria)

• It is a mandatory clause in griha manual.

• This criteria falls under building operation and maintenance.

OBJECTIVE

Validate the performance of the energy and environmental systems in the building as predicted during the

design and development stage, thermal comfort and visual comfort criteria.

COMMITMENT

A.) After occupying the building, conduct audits for the following within two years of full occupancy and

submit audit data as per the specified format. The energy consumption data submitted should be for at

least 12 months.

1. Energy audit

a. Energy consumption

b. Thermal comfort

c. Visual comfort

2. Water and waste audit

a. Water quality

b. Solid waste generation

c. Solid waste disposal process.

COMMITMENT

B.) After occupying the building, conduct sound level audit as specified in Criterion 29, to measure the

following:

a. Indoor noise levels

b. Outdoor noise levels

Note: Clause b is only applicable to projects that have attempted GRIHa Criterion 29:

Acceptable outdoor and indoor levels. the audit data should be submitted to ADaRSH (Association

for Development and Research of Sustainable Habitats) in the format specified in Criterion 29.

These audits should be conducted for typical representative days. The audit reports should be submitted to

ADaRSH in the specified format for validation of the information provided at the time of award of provisional

rating.

Incase the audit data is not corresponding with the data and documents provided at the time of

award of provisional rating, the provisional GRIHA rating will be taken back from the project. However, if the

audited data is corresponding with the data and documents provided at the time of award of provisional

rating, the final GRIHA rating will be awarded to the project.

The energy audit should be conducted by an energy auditor approved by the Bureau of Energy Efficiency,

Government of India and submit the report to teri. Water and waste audit should be conducted by a

competent authority.

Further, TERI will carry out thermal performance monitoring and visual comfort monitoring for typically

representative days. This is primarily to verify the data provided in various documents, and for which points

have already been awarded.

LONG TERM BENEFITS

Creating a database for a better energy future

• The mandatory energy audit and validation criterion in griha has enabled projects to record the building’s

resource consumption pattern.

• This will enable creation of a nation wide database for energy performance across different types of

buildings in all climate types.

• this will help achieve the national energy goals and ensure implementation of the national schemes such

as bee star rating for buildings etc.

By means of Energy Audit is therefore possible:

• To define energy balance of the building.

•To characterize the procedures of the prequalification of the systems.

•To characterize technical and economical opportunities.

•To reduce the plant management expenses.

•to improve the comfort

Energy Audit allow to:

•Understand and define effective energy costs

•Understand how is energy consumed

•Understand when is energy consumed

•Minimize waste of energy

•Maximize efficiency

•Optimize production of energy (also with renewable energy)

COMFORT AUDIT

The energy audit comprises of assessing the thermal and visual comfort of the building spaces. Thermal

comfort performance of the building is defined in terms of temperature and relative humidity maintained in

the building and visual comfort is defined in terms of average illumination level in all the building areas

measured at horizontal work plane. Thermal and visual comforts audits are conducted to verify that the

building’s HVAC and lighting system are functioning appropriately & providing required comfort to the

building occupants.
