Energy Savings in buildings

Technologies and measures which are aimed at reducing the use of energy in buildings could have several advantages, such as lower energy bills, increasing comfort of living or working, and reduced impact on the environment, including reduction of CO2 emissions. The options considered for energy savings particularly leading to CO2 emission reductions include the following:

Clean Development Mechanism market status:

Project developers of energy efficiency in buildings projects in the CDM pipeline mainly apply the following methodologies:

AMS-II.E “Energy efficiency and fuel switching measures for buildings”
AMS-II.C “Demand-side energy efficiency activities for specific technologies”
AMS-II.J “Demand-side activities for efficient lighting technologies”
AM0046 “Distribution of efficient light bulbs to households”
Further information on these metholodogies can be found here.

The energy efficiency household projects are currently representing 0.1% of the CDM projects in the pipeline. Presently, there are six CDM projects registered in energy efficiency for households - four of them are based on lighting/insulation and two on improved stoves. The lighting/insulation projects are located in India and one in South Africa. The improved stove projects are based in Zambia and Nigeria.


Example CDM project:
Title: Visakhapatnam (India) OSRAM CFL distribution CDM Project (CDM Ref. No. 1754)
The “Visakhapatnam (India) OSRAM CFL distribution CDM Project” involves the distribution of approximately 450,000 to 500,000 OSRAM long life Compact Fluorescent Lamps (CFLs) in the district of Visakhapatnam, which numbers about 700,000 households. The CFLs used are OSRAM DULUX EL LONGLIFE, and have the capacity of 15,000 hours and 80% lower energy consumption than a conventional light bulb.
Project investment: USD 2,036,000
Project CO2 reduction over a crediting period of 7 years: 51,116 tCO2e
Expected CER revenue (assuming USD 10/CER): USD 511,160

Energy efficient refrigerators

Videocon Refrigerator, 3 Star Indian BEE rating

Refrigerators are used in households across the world to store food at a temperature of about 3 to 5 °C (37 to 41 °F) in order prevent it from spoiling. This technology description focuses on refrigerators for residential use and on energy efficiency performance only. It does not take into account potential GHG effects caused by the refrigerant.

Clean Development Mechanism market status:

The CDM methodology AM0070: Manufacturing of energy efficient domestic refrigerators opens the possibility to include projects which improve the energy efficiency of refrigerators under the CDM. However, as of January 2011, no project has been registered under this methodology, yet.

Energy Efficiency and Saving in the Agri-food Industry

The agri-food industry comprises an integrated complex production chain which ranges from the primary agriculture to the mature food and beverage sector. It is considered as one of the largest sectors  worldwide with significant contribution to the economic advancement of nations and major social impact.

To create a replicable financing model to ensure that the planned Municipal Energy Efficiency projects in Tamil Nadu state are successfully implemented using performance contracting and energy service companies (ESCOs).


28° 36' 0" N, 77° 12' 0" E
Main activity and output: 
  • Assist Tamil Nadu Urban Infrastructure Financial Services Limited (TNUIFSL) with auditing and project implementation, and facilitate their interaction with ESCOs;
  • Guide ESCOs and TNUIFSL during the monitoring and verification process to apply the International Performance Monitoring and Verification Protocol (IPMVP)  and assess/demonstrate its suitability for Indian Watergy projects;
  • Create a tool kit to enable other cities and states to replicate the financing approach;
  • Develop a succinct case study describing the project;
  • Organise a workshop to disseminate the model to other states;
  • Replicate the application of performance contracting to municipal water supply energy efficiency projects;
  • Field test IPMVP protocol for water pumping in India for first time.
Expected impact: 
  • The proposed project will be crucial to ensuring the success of the Tamil Nadu Municipal Energy Efficiency Programme, which in turn is crucial for creating confidence in the use of performance contracting for municipal energy efficiency in India, and for increasing confidence in India's nascent ESCO industry;
  • After many years of promoting Watergy in India, its benefits are now widely accepted; the barrier has been financing. This improved confidence in financing with performance contracting will spur its widespread adoption for Watergy in cities and towns across India, including the entire state of Tamil Nadu;
  • Significant carbon dioxide reductions.
