Sustainable Buildings and Energy Efficient Cooling in Bangladesh

Buildings and construction generate nearly 40% of global CO2 emissions. Throughout their life cycle, buildings have extensive direct and indirect negative impacts on the environment due to their intensive use of resources, such as energy, water, and waste production. Moreover, improperly-designed buildings could also have adverse effects on their occupants, causing thermal discomfort, sickness and lack of productivity.

GREEN BUILDINGS concept was developed as an integrated process, focused on relation between built and natural environment. Energy and water use reduction, healthy indoor environmental quality improvement, use of smart construction materials, energy efficient cooling and other energy end-use technologies and building planning are key consideration of green buildings. A green building rating system is a tool that evaluates building’s energy performance and environmental impacts. It comprises of set of criteria relating to the design, construction, and operational process which are evaluated and leads to a label/ certification award to be disseminated for public awareness and transactions, complementing the system of building energy efficiency codes. Globally, there is a diverse range of both mandatory and voluntary rating systems driven by different objectives, covering various aspects of building design and use.

COOL ROOFS are designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles, and have grown in prominence in recent years, notably in the US. But they are only just beginning to be used in developing countries. This energy conservation measure could be a relevant cost-effective solution to reduce energy use for space cooling in buildings, to mitigate heat stress inside the buildings, specially in low-income neighborhoods, and to alleviate urban heat islands (UHI), the phenomenon whereby urban regions experience warmer temperatures than their rural surroundings.

This Webinar will include an overview of international and regional (Asia-specific) experiences of various green and energy efficient building rating systems and cool roofs programs. The event is organized by the World Bank under its TA initiative, funded by ESMAP and CIF-TAF, “Implementation of Bangladesh Building Energy Efficiency and Environment Rating System (BEEER) and the development of Cool Roof Programs for Urban Heat Island Mitigation in Dhaka”, being implemented in collaboration with Bangladesh’s Sustainable and Renewable Energy Development Authority (SREDA) and other partners.
