PREFACE
We are pleased to publish the Proceedings of
the short course on ‘Energy Efficiency’ organized by the Centre for
Energy Studies (CES) of Bangladesh University of Engineering and
Technology (BUET) and German Technical Cooperation (GTZ).
Energy has been the primary input behind the
evolution of the human civilization up to the new millennium marked with
astounding technological developments. However, while the demand for
energy is ever escalating the commercially viable and exploitable
resources for bulk energy are getting shrunk in the world. Therefore,
alongside ensuring access to energy for all, affordable and pragmatic
technical means need to be devised and implemented so that energy can be
saved through reducing the consumption.
This proceedings focuses through a number of
articles contributed by the noted experts in respective fields that
energy saving and auditing i.e. conservation is an interdisciplinary
topic that requires integration of architectural, mechanical and
electrical engineering solutions on one side and the financial analysis
on the other side. The articles illustrate how energy saving can be
affected through the architecture, lighting, motors and transformers,
ventilation and air conditioning, heating systems and cogeneration in
residential or industrial and commercial buildings/plants.
We take this opportunity to acknowledge our
profound gratitude to Prof. Dr. A. M. M. Safiullah, the Hon’ble
Vice-Chancellor of BUET, all the resource persons, Mr. Erich Otto Gomm,
of GTZ and Mr. Mohammad Zahirul Islam, Librarian of BUET for their
contributions towards the publication of this proceedings. The last but
not the least, our special appreciation goes to Mr. Md. Abdur Rab of CES
for his untiring efforts for publishing this Proceedings.

Global Perspective
Welcome to the Web site of FEMP's Purchasing Specifications for Energy-Efficient Products. Access the product specifications, interactive energy cost calculators, model procurement language, and other resources to help in the purchasing of energy-efficient products by using the navigation to the left.
As the world's largest volume-buyer of energy-related products, the federal government can reduce energy consumption and achieve enormous cost savings by purchasing energy-efficient products. Federal buyers are now required by the Energy Policy Act of 2005 to purchase products that are ENERGY STAR®-qualified or FEMP-designated. (These products are in the upper 25% of energy efficiency in their class.) The purchasing requirements are codified by FAR Part 23. In addition, Executive Order 13221 requires that federal agencies purchase products with low standby power.
FEMP helps federal purchasers identify these types of highly efficient products. A list of the all of the ENERGY STAR-qualified or FEMP-designated products is available for download (PDF 98 KB, 1 p). Read our fact sheet to learn more about FEMP's activities (PDF 251 KB, 2 pp). Download Adobe Reader.
Purchasing "green" products helps to reduce our impact on the environment. The Office of the Federal Environmental Executive (OFEE) provides links to green purchasing information.
Companies selling energy-efficient and green products and services have a special opportunity in the federal sector. Federal agencies spend at least $10 billion per year on purchases of energy-using products. Basic information on how to do business with the federal government is offered in the publication Federal Procurement Opportunities for "Green" Vendors (PDF 1 MB, 8 pp). Download Adobe Reader.
Energy Cost Calculators
The calculators below allow users to enter their own input values (e.g., utility rates, hours of use, etc.) to estimate the energy cost savings from buying a more efficient product. Some are Web-based tools; others are Excel spreadsheets provided by ENERGY STAR® for download (as indicated.) Other resources include FEMP Building Life-Cycle Cost (BLCC) software for detailed life-cycle cost analysis and MotorMaster+ software for identifying "Premium" efficiency motors.

Energy Efficiency
(EE) encompasses all changes that result in a reduction
in the energy used for a given energy service (heating,
lighting...) or level of activity. This reduction in the
energy consumption is not necessarily associated to
technical changes, since it can also result from a
better organization and management or improved economic
efficiency in the sector (e.g. overall gains of
productivity).
This definition of energy efficiency is provided by the
World Energy Council (WEC)

EE Methodologies
The following CP methodologies were used as an input to
develop the “Company Energy Efficiency Methodology”:
- Energy Audit Methodology:
a 10-step methodology developed under the Indo -
German
Energy Programme (IGEN) in cooperation with Bureau of Energy Efficiency (BEE) under the Ministry of Power of India ( www.energymanagertraining.com) - Energy Audit Methodology: an 8-step approach developed by the National Productivity Council of India (not published)
- Developing an Energy Management System: a 9-step approach developed by the Sustainable Energy Authority of Victoria as part of the “Energy and greenhouse management toolkit”. (http://www.seav.vic.gov.au/advice/business/EGMToolkit.asp)

Policies and Energy Efficiency
Energy Efficiency Programmes
Energy Efficiency
and Renewable Energy (EERE)
EERE is a US Department of Energy Program and its
mission is to enhance energy efficiency and productivity
and bring clean, reliable and affordable energy
technologies to the US marketplace.
Energy Star Program
Introduced as a voluntary program in 1992, Energy Star
is a United States government-backed program. It
provides technical information and tools that consumers
can choose from for energy efficiency solutions and best
management practices, making it possible to save money
while protecting the environment for future generations.
The Energy Project
Pelangi is one of the partners in Energy Project, an
informal network of non-governmental organizations
(NGOs) from low income countries in Africa, Asia,
Central and Eastern Europe (CEE), and Latin America. The
focus of the energy project is energy sector policy. The
project aims to:
- Support and build the capacity of Energy Project partners, and others, to be able to address issues related to energy, climate and development at their respective national or regional level.
- Reverse the current general direction of the flow of information among NGOs in relation to energy, climate and development so that information increasingly flows from the South and CEE to the North, contributing to a more equitable hearing in international and IFI decision making processes
SAVE Programme
SAVE is a European Union-wide program dedicated
exclusively to promoting energy efficiency and
encouraging energy-saving behavior in industry, commerce
and the domestic sector as well as in transport through
policy measures, information, studies and pilot actions
and the creation of local and regional energy management
agencies.
