Agenda

From Montreal to Kyoto

• Montreal Protocol (CFC’s / Ozone layer)– Address the threat of depletion to the ozone layer through the

release of CFC’s.

• Kyoto Protocol (CO2 / Global Warming)1. Enhancement of energy efficiency

2. Increase use of new and renewable forms of energy

3. Limit or reduce emissions of greenhouse gases

Bureau of Energy EfficiencyA Statutory body under Ministry of Power, Government of

India

Trane is a certified ESCO with the

BEE

As a small initiative Trane recently

signed MOU with IDBI for India

Chiller Energy Efficiency Project

• Applicable for commercial buildings or building

complexes that have;

• Connected load >500 kW

• Contract demand >600 kVA.

• Also applicable to all buildings

with a conditioned floor area of >1,000 m2 (10,000 ft2).

• Recommended for all other buildings.

•The code is presently under voluntary adoption in the

country.

LEED-INDIA

• LEED-INDIA provides building owners, architects,

consultants, developers, facility managers and

project managers the tools they need to design,

construct and operate green buildings.

• LEED-INDIA promotes a whole-building approach to

sustainability by recognizing performance in the

following five key areas:

Sustainable site development

Water savings

Energy efficiency

Materials selection and

Indoor environmental quality

Kohinoor Hospital was awarded Platinum

by Leed- India very recently.

LEED / ASHRAE

• LEED / U.S. Green Buildings

– New Construction

– Existing Buildings

– Commercial Interiors

– Core and Shell

– Homes

– Neighborhood Development

• ASHRAE

– Advancing heating, ventilation,

air conditioning and

refrigeration to serve humanity

and promote a sustainable

world through research,

standards writing, publishing

and continuing education

– Extensive guidelines covering

every aspect of hvac and high

performance buildings.

GRIHA Rating System

Chiller Ratings (Revisited)

• If energy efficiency is such an important concept, we

should know how to measure it.

– IPLV (integrated part load value)?

– Hour-by-hour modelling analysis?

Chiller Ratings (Revisited)

• Clearly there is a consensus that energy efficiency is

desirable for economic, environmental and social

needs.

• We should also know how to measure it accurately.

• Currently IPLV is being used as a substitute for

executing a complete hour to hour modelling

analysis.

• IPLV was created by AHRI and is often promoted by

some manufacturers to analyse the chiller

performance.

Chiller Ratings (Revisited)

• AHRI has acknowledged that it does not accurately

represent a chiller plant operating characteristics.

• Decisions based on this incomplete data often results

in poor predictions of energy use and is important to

use the right tools to ensure optimal economic and

environmental solutions.

Understand the Background of Integrated Part Load Value

AHRI Standard 550/590

ASHRAE 90.1 uses IPLV to define the

minimum part-load value

• What is the scope of IPLV use?

• How is the equation defined?

• What are the assumptions behind

the equation?

• How does it hold up comparing

multiple chillers in a plant?

• What other factors should we be

aware of?

Derivation of Integrated Part Load Value (IPLV)

• What is the scope of IPLV use?

Average Part-Load Efficiency for a Single Chiller ONLY

AHRI Standard 550/590

A closer look at Chiller ratings

• IPLV was created to help compare unloading

characteristics of similar chillers and not to infer any

economic savings.

• IPLV uses only four operating point with weighting

factors i.e 100%,75%, 50% and 25%.

• IPLV evaluates only single chiller and not multiple

chiller as efficiency is related to many variables.

• IPLV assumed entering condenser water temperature

relief.

• IPLV is dictated by four distinct operating buckets

simultaneously on load and lift reduction.
