Green Buildings


Compact fluorescent lamp (CFL)?

What is it and why it helps?
A Compact fluorescent lamp (CFL) is an energy efficient alternative and are much more efficient than incandescent bulbs. A CFL uses only one-fifth as much electricity as an incandescent lamp to provide the same level of illumination. A 15 W and 20 W CFL can replace a 60 W and 100 W incandescent bulbs respectively.

Building Operation and Construction

The Energy Audit is conducted on December 2010 for both buildings, and it is estimated that the total use of energy-mix in the buildings is optimally contributed to overall energy consumption demand. The building AAGC and Main CSE building has 98.39 kWh and 89.30 kWh sanctioned load from the grid supply respectively. The annual electricity bills for buildings, diesel and solar energy generation data collectively finds that Main CSE building’s (77%) share in total energy consumption was more than three times that of AAGC (22%) building (see Graph 01).

Energy Conservation Building Code

The 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.

National Building Code 2005

The National Building Code of India (NBC), a comprehensive building Code, is a national instrument providing guidelines for regulating the building construction activities across the country.

Research

The research as a part of COE activity at CSE includes policy research on decentralized wastewater management (DWWT), rainwater harvesting (RWH) and water efficiency(see presentation). As a part of CoE mandate, CSE has prepared and submitted various reports and policy papers in the area of sustainable water management to Ministry of Urban Development (MoUD).

Knowledge Dissemination

CSE as a CoE also functions as knowledge centre for Sustainable Water Management, wherein it collates and disseminate information related to urban water management through its website. CSE’s website has dedicated interactive online information on water management and in particular CoE activities like RWH, DWWT and water efficiency.Also, other CSE’s websites like India Environmental Portal, Down to Earth, rainwater harvesting widely cover issues related to the above activities on a regular basis.
