World Energy Scenario Total consumption of marketed energy is expected to expand by 54% from 404 quadrillion Btu in 2001 to 623 quadrillion Btu in 2025 World oil reserves are expected to last for 45 years and gas reserves for 65 years.

Total consumption of marketed energy is expected to expand by 54% from 404 quadrillion Btu in 2001 to 623 quadrillion Btu in 2025

World oil reserves are expected to last for 45 years and gas reserves for 65 years.

Indian Scenario Absolute primary energy consumption is only 1/29 th of world, 1/7 th of USA, 1/1.6 th of Japan but 1.1 times that of Canada, 1.3 times that of France. 53% of the primary energy source available is coal.

Energy IN-efficiency is rampant Most commercial buildings have energy performance index (EPI) of 200 to 400 kWh/sq m/year Similar buildings in North America and Europe have EPI of less than 150 kWh/sq m/year

Most commercial buildings have energy performance index (EPI) of 200 to 400 kWh/sq m/year

Similar buildings in North America and Europe have EPI of less than 150 kWh/sq m/year

Energy-conscious building design has been shown to reduce EPI to 100 to 150 kWh/sq m/year in India – development of such buildings is restricted to environmentally-sensitive corporates Large scale energy-efficient building design is limited due to split incentives - builders fear that they would bear the costs, while tents would enjoy benefits

Electricity Use in the Commercial Sector is exploding

What are Energy Conservation Building Codes? ECBC set minimum energy efficiency standards for design and construction ECBC encourage energy efficient design or retrofit of buildings so that It does not constrain the building function, comfort, health, or the productivity of the occupants Lifecycle costs (construction + energy costs) are minimized

SCHEME FOR RATING OF BUILDINGS The Star Rating Program for buildings is based on actual performance of the building in terms of specific energy usage (kWh/sq m/year). This programme would rate office buildings on a 1-5 Star scale with 5 Star labeled buildings being the most efficient. Five categories of buildings - office buildings, hotels, hospitals, retail malls, and IT Parks in five climate zones in the country have been identified

Office buildings in the following 3 climatic zones for airconditioned and non- air-conditioned: • Warm and Humid • Composite • Hot and Dry It will be subsequently extended to other climatic zones and building types

What is Star Rating? Energy Star is an international standard for energy efficient consumer products. It was first created as a United States government program in 1992, but Australia, Canada, Japan, New Zealand, Taiwan and the European Union have also adopted the program

What is Star Rating? Star rating is a system initiated by BEE (Bureau of Energy Efficiency) to determine the energy efficiency of an appliance, like air-conditioners. Depending on their energy efficiency they are rated on a scale of 1 - 5 stars. Higher the number of stars, better is their energy efficiency.

The star rating system is a way of measuring energy efficiency. It’s applied to all electronic products such as Refrigerators, TVs , ACs and so on. Every AC model can get its EER tested and get a star rating. Currently, it’s voluntary, not mandatory for companies to get a star rating for their models.

How is Star Rating Calculated For example in case of AC’s Calculate EER by following method: BTU/(3.41* power input) and then from the table get the star rating.

Some terms for Star Rating Projected Annual Energy Consumption Here the tested Energy consumption of each unit is measured and calculations for annual energy consumption are made as PAEC= Et*365/1000 Where Et is the tested energy consumption in Wh per 24 hrs rounded to nearest whole number

Projected Annual Energy Consumption

Here the tested Energy consumption of each unit is measured and calculations for annual energy consumption are made as

PAEC= Et*365/1000

Where Et is the tested energy consumption in Wh per 24 hrs rounded to nearest whole number

Calculation of Star Rating The star rating is calculated using the formula: Star Rating Band = Knf*V adj*Cnf Knf is constant mutliplier (kWh/litre/year) V adj is total adjusted volume for frost free Cnf is constant fixed allowance (kWh/year)

The star rating is calculated using the formula:

Star Rating Band = Knf*V adj*Cnf

Knf is constant mutliplier (kWh/litre/year)

V adj is total adjusted volume for frost free

Cnf is constant fixed allowance (kWh/year)
