Energy Conservation Building Code (ECBC)

Energy Conservation Building code

Energy Conservation Building Code (ECBC) was launched by Ministry of Power, Government of India in May 2007, as a first step towards promoting energy efficiency in the building sector. The Ministry of Power, Govt. of India is implementing ECBC in the States of India in consultation with the Bureau of Energy Efficiency (BEE) (Govt. of India, Ministry of Power). The ECBC was developed under the guidelines of BEE with significant inputs from various other stakeholders such as practicing architects, consultants, educational institutions and other government organizations. The purpose of ECBC is to provide minimum requirements for energy efficient design and construction of buildings and their systems without compromising on the comfort of the occupants.

New Construction

The Energy Conservation Building Code (ECBC) was developed by the Govt. of India for new commercial buildings on 27th May 2007. ECBC sets minimum energy standards for commercial buildings having a connected load of 100kW or contract demand of 120 KVA and above. While the Central Government has powers under the EC Act 2001, the state governments have the flexibility to modify the code to suit local or regional needs and notify them. Presently, the code is in the last stage of notification.

Existing Buildings

In existing building we could save upto 30 percent of electricity by applying ecbc code. For this we could do retrofitting in the existing building and can make building close to ECBC compliant building.

The ECBC provides design norms for

Building envelope, including thermal performance requirements for walls, roofs, and windows
Lighting system, including day lighting, lamps and luminaries' performance requirements
HVAC system, including energy performance of air distribution systems
Electrical system
Water heating and pumping systems, including requirements for solar hot-water systems.

First ECBC cell of India was established in UPSDA to facilitate the drafting of ECBC code, awareness about ECBC and also make some demo projects to showcase how an ECBC compliant building is constructed and its contribution in energy saving.

In Uttar Pradesh construction of Uttar Pradesh Electricity Regulatory Commission (UPERC) office as a model building based on ECBC provision, has been completed and its detailed information including building material used and financial detail is as follows

Case Study of ECBC Compliant Building

Whether your building can be a ECBC compliant-building?

For those who want to know whether your building can be an ECBC compliant building can fill in the form attached in annexure-A giving few basic details of the building and email us.

Annexure-A

For those who are interested to build their building as per ECBC norms thus making it an ECBC-compliant building can fill in detail application form attached in annexure-B and email us.

Annexure-B

For those who are interested to build their existing building as per ECBC norms by retrofitting, thus making it an ECBC-compliant building can also fill the form.

In order to promote ECBC compliant/Energy Efficient building in Uttar Pradesh consultation is provided free of cost.

Frequently Asked Questions for Energy Conservation Building Code (ECBC)

Energy Saving Calculator

The purpose of this energy calculator is to help you determine the average electricity consumption of each of your electrical appliances and their contribution to your monthly electricity bill. Also it shows how much electricity / money you can save if old appliance is replaced with Energy Efficient appliance.

How to Use the Calculator

Step 1: Fill the Cost of Electricity.
Step 2: Fill the quantity for each of the appliances.
Step 3: The calculator will display the electricty consumption (in kWh) & electricty saving (in kWh) for each appliance per annum and sunbsquent cost saving.
For example: If you are using 1 bulb of 100W for 8 hour a day (200 days in a year), then you should fill in as follows:
Cost of Electricity = Rs 7.0 per unit (Assumed)

Appliance	Rating / Wattage (W)	Qty	No.of Hours of use per day	No.of Day	Annual Electricity Consumption (kWh)	Annual Electricity Bill Cost (IN Rs)	Energy Efficient Appliance	Energy Efficient Appliance Rating / Wattage (W)	Annual Electricity Consumption (kWh)	Annual Electricity Bill Cost (IN Rs)	Annual Electricity Saving (kWh)	Annual Electricity Bill Saving (IN Rs)
Incandescent Bulb	100	1	8	200	160	1,120.00	LED Bulb	9	14.4	100.80	145.6	974.40

The calculator shows that your Incandescent Bulb consumes on ..160... kWh per annuam and it contributes Rs .1120.00.. to your annual electricity bill. By replacing the old bulb with Energy Efficient 9 watt LED bulb you can reduce your consumpation up to 145.6 kWh per annum which reduces your electricity bill from Rs 1120.00 to Rs. 100.80
