Criteria for GRIHA rating 99
Criterion 33 Operation and maintenance
Objective
To ascertain effi cient functioning of the building’s systems through regular monitoring of building’s
energy and water consumption and implementation of appropriate operation and maintenance
program.
33.1 Commitment
33.1.1 Ensure regular monitoring of building’s energy and water consumption by installing digital
meters as per the following:
1. Electrical meters installed to measure energy units purchased from the utility and
energy units generated on site (through DG/ GG sets).
2. Electrical sub meters for measuring energy consumption by HVAC plant, AHU fans and
indoor lighting.
3. BTU meters to be installed for each chiller at entering and leaving points to measure
the cooling generated by chillers.
4. BTU meter to be installed on the chilled water loop to measure building’s total cooling
demand.
5. Water meter should be installed at all main supply points to measure the total water
consumption of the building.
33.1.2 Provide a core facility/service management group that will be responsible for the O&M of the
building’s electrical and mechanical systems after installation. In case of small-scale/single-
owner commercial buildings, the owner or the occupants themselves should undertake the
responsibility for the O&M of the building’s systems after installation.
33.1.3 Include a specifi c clause in the contract document of the systems supplier for the
commissioning (installation and test run) and systematic handing over of all electrical
and mechanical systems to the core facility/ service group responsible for the O&M of the
building systems after installation.
33.1.4 Include a specifi c clause in the contract document of the systems suppliers for providing
training to the core facility/ service group responsible for the O&M of the building systems
after installation, on the operating instructions/dos and don’ts/ maintenance requirements,
of specifi c systems.
If the systems supplier themselves have been assigned the responsibility of the O&M after
system installation, this clause is not applicable.
33.1.5 Prepare a fully-documented O&M manual/ CD/ multimedia/ an information brochure listing
the best practices/dos and don’ts/maintenance requirements for the building’s systems
along with the name and address of the manufacturer/supplier of the respective systems.
This should be carried out by the owner/builder/occupants/service or facility management
group.
33.2 Compliance
33.2.1 Submit drawings and documents showing locations of energy and water meters.
33.2.2 Applicant shall provide the proof of provision for a core facility/service group responsible
for the O&M of the building’s systems after installation. This should be supported with
