The results of Dr Hashemi's research have been documented in numerous publications including refereed journal articles, conference papers, book chapters, edited books and patents. His research interests can be classified under two main areas:
Building Performance Evaluation
Dr Hashemi's primary research is on building performance evaluation/simulation with a focus on energy efficiency and health and wellbeing in buildings. The key research areas include:
- Indoor Air Quality
- Thermal Comfort
- Natural Lighting
- Energy Efficiency; and
- Performance Gap
His research on the above areas has been through various means and methods including physical tests, post occupancy evaluation, simulation and/or laboratory tests. Probably his most significant achievement during the recent years has been the design and development of an internationally-patented, multi-award winning thermal shutter system which can also act as a natural light reflector, solar shade and a secondary security device. The invented product benefits from innovative drive mechanisms and control strategies mixed with the most advanced materials to achieve significant savings of over 60 per cent in electric lighting and over 63 per cent in heat-losses through windows.
Energy and health and wellbeing in housing, and particularly in low-income housing, is another area of his research which he started at the University of Cambridge and is now continuing at UEL. The research intends to identify, and then begin to propagate, methods of reducing the energy consumption of low-income housing.
Indoor air quality and air pollutants, in general, and moisture, dampness and the risk of mould growth, in particular, are the other areas of his research. Dampness is affecting a significant share of buildings in Europe, North America, Australia, India and Japan making it a major issue around the world. Dr Hashemi's research aims to improve energy efficiency while reducing the risks of dampness and mould growth in buildings.
Offsite/Modern Methods of Construction
In his PhD, Dr Hashemi studied the relevance of Modern/Offsite Methods of Construction to delivering sustainable housing in the UK and in developing countries. His research then expanded into more recent issues such as Mass Customisation and Building Information Modelling (BIM) in offsite construction. He has been doing research and publication in these areas along with a team of experts in Europe, Australia, New Zealand, Japan and the Middle East. The main objectives are to investigate the reasons for the success and failure of prefabricated methods in different countries and to address housing shortages in both developed and developing countries.
