Scenario Buildings are responsible for 40% of energy use in the world

42% of global water consumption and 50% of the global consumption of raw material used in Building

India’s floor build up are is increasing 1% per year compare to the 2004-05 where it was 40.5 million sq. meter

8% rise in annual energy consumption in residential and commercial sector ,its was 14% in 1970s to 33% in 2004-05

Building is having major concern during construction for water ,material and resource management.

Micro level planning needs to incorporate for site development and planning for building

Green building depletes the natural resources to minimum during its construction and operation.

International rating programs

BREEM –building research establishment’s Environmental assessment method adopted in UK in 1990

CASBEE- comprehensive assessment system for building Environmental Efficiency – adopted in Japan ,2001

GB Tool- tool developed by International framework committee for the green building challenges since 1998s

LEED- leadership in Energy and Environmental design (LEED) was developed and piloted in the US ,since 1998s

HK BEAM- The Hong kong building Environmental Assessment method launched in dec 1996

Introduction to GRIHA Stands for Green rating for integrated habitat assessment

Tool used for building’s environmental performance in context to Indian atmospheric condition

Rating shall evaluate the environmental performance of a building holistically over its entire range of life cycle .

The rating applies to new buildings- commercial ,residential and Institutional

Endorsed by MNRE ,GoI from Nov 2007 onwards

It is five star rating system for green building which emphasis on passive solar and optimizing visual and thermal comfort.

GRIHA integrate all relevant indian codes and standards for buildings and act in tool

There are 34 set criteria further divided into- mandatory & optional

© 2013 UPESOct 2013Nov 2013

Scoring points under GRIHA

Points are earned by meeting the design and performance

Each criteria has assigned respective points, thus project needs to meet with each criteria and earn max points

Few criteria are self validating in nature ,other like (thermal and visual comfort . Energy consumption ,noise control criteria, indoor pollution level) needs to validated on the site

There are 34 criteria ,broadly classified into two categories : Applicable

Selectively applicable

Applicable criteria has further sub categories : Mandatory & Optional

© 2013 UPESOct 2013Nov 2013

Applicable criteria

The criteria that are not applicable for a project shall be determined by the ADaRSH during registration .

Information about top soil quality ,mature trees on site ,hot water demand ,quantum of waste water generated ,groundwater table,

These respective criteria as mention above shall not apply in case if the non applicability condition applies

The project will be rate on the applicable criteria basis

Building operation and Maintenance Criterion 32 : Energy audit & validation

Criterion 33: Operation and maintenance

© 2013 UPESOct 2013Nov 2013

Criterion 32 : Energy audit & validation Objective

• Validate the performance of the energy and environment system in the building as predicted during the design and development stage

Commitment

After occupying the building ,conduct energy audit with in 2 years

Conduct audit during full occupancies

Submit audit data as per the format

Energy consumption data should be at least past 12 month

Energy audit report to be prepared by the approved certified BEE Energy auditor

Energy audit Water and waste audit

Energy consumption Water quality

Thermal comfort Solid waste generation

Visual comfort Solid waste disposal process

© 2013 UPESOct 2013Nov 2013

After occupying the building ,conduct sound level as per specified in criterion 29

a. Indoor noise level

b. outdoor noise level

Energy audit should be conducted by BEE certified Energy auditor Water and waste audit should be conducted by competent authority

Earn point -0

Compliances

• Completed audit form signed by the competent authority

• Demonstrate all the energy and environment system of the building are performing as predicted and match the information provided at the time of award of GRIHA rating

• Energy audit activity certificate provided by the EA approved by BEE, GoI

Appraisal The energy system and water and waste management system of the building are performing

as predicted and match the information provided at the time of GRIHA rating (mandatory clause)

© 2013 UPESOct 2013Nov 2013

Criterion 33: Operation and maintenance

Objective • To ascertain the efficient function of the building system through the monitoring the

building Energy and water consumption and maintenance program

Commitment Validate and maintain “ green” performance level/ adopt and propagate green practices

and concept

Ensure the commissioning document of all electrical and mechanical system to be maintain by the owner/supplier /operator

Provide core management group who will be solely responsibly for O&M of building , prepare CD/multimedia, manuals for operation and information brochure

Ensure regular monitoring of building by installing digital meters as per the following Electrical meters installed to measure energy units purchased from the utility and energy units

generated on site (through DG/ GG sets).

Electrical sub meters for measuring energy consumption by HVAC plant, AHU fans and indoor lighting.

BTU meters to be installed for each chiller at entering and leaving points to measure the cooling generated by chillers.

© 2013 UPESOct 2013Nov 2013

BTU meter to be installed on the chilled water loop to measure building’s total cooling demand.

Water meter should be installed at all main supply points to measure the total water consumption of the building

Compliance Appendage of specific clause in the contract documents for the commissioning of all the

electrical and mechanical system to be maintain by the owner ,supplier or operator as per applicable GRIHA documents

Provide core management group if possible

Project manager is responsible for all activity

Submit drawings and documents showing locations of energy and water meters.

Applicant shall provide the proof of provision for a core facility/service group responsible

Applicant shall provide proof of inclusion of specific clause in the contract document of the system supplier for commissioning (installation and test run) of all electrical and mechanical systems

© 2013 UPESOct 2013Nov 2013

Appraisal (Max. 2 points)

Provision of meters for monitoring building’s energy and water consumption, (1point mandatory).

Provision for a core facility/service group responsible for the O&M of the building’s systems after installation Inclusion of a specific clause in the contract document of the systems supplier for commissioning (installation and test run) of all electrical and mechanical systems as per clause

Development of a fully documented O&M manual/ CD/ Multimedia / information brochure enlisting the best practices for O&M of the building’s systems, as per clause (1point mandatory)
