The prospects of zero energy building as an alternative to the conventional building system in Bangladesh (A review)

Mehedhi Hasan, AMM Shamsul Alam*, Mohammad Alamgir Hossain and AMM Nurul Alam

Energy consumption in commercial and residential buildings worldwide accounts for about one-third of the world’s energy and one-quarter of greenhouse gas emissions. If current trends continue, by 2025, buildings worldwide will be the largest consumers of global energy, using as much power as the transportation and industrial sectors combined. Recent studies have found that improving energy efficiency in buildings is the least costly way to reduce a large quantity of carbon emissions. By changing energy management practices and instituting technologies that enhance energy efficiency, building owners and managers can reduce energy consumption by up to 35%. However, energy efficiency efforts in buildings alone cannot address future demand for more energy by this sector. To achieve breakthrough solutions to this problem, it is evident that a coordinated effort in a whole-building systems approach that emphasizes the necessity of integrating renewable on-site or distributed generation and energy efficiency is required to design the buildings of the future. Several International Energy Agency (IEA) countries have adopted a vision of so-called ‘net zero energy buildings’ (NetZEBs) as the long-term goal of their energy policies. This NetZEB is very new in Bangladesh and it started building green buildings which will lead to NetZEB shortly. However, Bangladesh has to comply with the IEA and must accept the zero-energy building concept.
