“Study on Energy Efficiency in Public Buildings in Bangladesh (EEPB)” was implemented by Sustainable and Renewable Energy Development Authority (SREDA), together with Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH and Ministry of Housing and Public Works. EEPB was funded by Kigali Cooling Efficiency Program (K-CEP), and the Asian Infrastructure Investment Bank (AIIB) played an instrumental role in this study.
The aim of the study was to determine the energy savings potential in public buildings, the very first comprehensive study in Bangladesh in this regard. A team of national and international energy audit experts conducted 2-step energy audits in 12 selected public buildings and provided recommendations for maximising the efficiency of energy consumption for the buildings. Through the study it was found that with better insulation, retrofitting, replacement of inefficient appliances, and introducing rooftop solar systems – more than 1 million kilo-watt hours of energy could be saved in these buildings with a nominal investment of around 1 million US Dollar and payback period of 5 to 12 years.
The study showed that 10 out of the 12 audited buildings could generate about 1 million kilo-watt hours of electricity from rooftop solar. If the energy saving potential is extrapolated for more than 250 selected PWD maintained buildings in Dhaka region, about 11 to 15 million kilo-watt hours of electricity could be saved. The saving potential is equivalent to the electricity used by one thousand homes in a year. PWD has more than 13,000 government buildings in the country. Other Government agencies also own thousands of public buildings. Considering all of them, the potential savings amount could be astounding.
