The Environmental Design and Performance Research Group (EDPRG) aims to facilitate an experimental learning hub where the research group members can collaborate and undertake practical research that learns from real-life case studies.

ERDG started in 2016 with research undertaken to identify sustainable design strategies that would deliver on low carbon and thermally comfortable buildings by investigating the performance of existing buildings and optimising the new-built building design. The research methodologies and results provide a platform for research-led teaching.

PhD researchers

Mr Hashem Taher

Hashem's research aims to investigate and determine the thermal effects of various urban green systems (UGS); trees, living facades and high albedo pavements, at street level, to assist in the mitigation of urban heat island (UHI) and reduce Carbon Dioxide (CO2) emissions within Central London, UK. His study quantifies the critical contribution by modelling urban vegetation densities or applying a high albedo pavement model for 2018 and then future climate scenarios 2050 and 2080. The research utilised ENVI-met software simulations, field measurements to validate the results and a questionnaire survey. Secondly, a questionnaire survey was designed to determine the intangible benefits of the urban green systems and how it would influence pedestrians' activities within the streets after applying them, in addition to determining the preferred UGS intervention with the preferred percentage by pedestrians. The research design strategy is to motivate pedestrians to walk for extended periods and facilitate alignment to follow the healthy streets initiative advocated by Transport for London and assisting in the transition for London to be the world's largest national park city by 2050, based on the current Mayor of London Plan.

Mr Bertug Ozarisoy

Bertug's research studies the energy use and its measures in buildings aiming to improve the energy efficiency of residential tower blocks (RTBs) in Famagusta, Northern Cyprus. The study employed a mixed-methods research design approach, which was based on a thorough field study that consisted of a questionnaire survey conducted with residents of the housing estate of the case study, to explore the occupants' thermal comfort and preferences, their home energy use and cooling strategies, occupancy patterns, as well as energy bills, amongst other variables. Concurrently, indoor air temperature and relative humidity (RH) measurements were collected during the same period. The subsequent phase of the research examined the existing energy performance of those representative RTBs under investigation by modelling and simulating dominant representative occupancy profiles using the Integrated Environmental Solutions (IES) software suite. Notably, dynamic thermal modelling and simulations of base-case RTBs were adopted to provide succinct information on occupancy schedules over a long period of time.

Previous EDPRG members

Dr Sahar Zahiri

Sahar is currently a Research Fellow in Sustainable Building Performance at the School of Architecture, Oxford Brookes University, focusing on smart local energy systems projects. Sahar joined UEL as a Research Associate to BC-SDBE project in 2016.  She worked with the principal investigator (PI) of the project Dr Heba Elsharkawy on research activities to develop education for sustainability in Egypt and to identify appropriate retrofit strategies for social housing dwellings and office buildings in East London to reduce energy use and overheating risks. Additionally, Sahar assisted the project's PI to carry out other project-related activities such as organising training events for delegates from Egypt, as well as international conferences. She has been a key member of the team in undertaking research on building performance and the impact of climate change on the health, comfort and wellbeing of occupants of retrofitted residential buildings. Sahar was also involved in teaching activities to support students in building simulation modelling and analysis and technical studies. 

Dr Wei Shi (completed in 2018)

Wei Shi joined the Environmental Design Research Group (ERDG) in 2016. He conducted the research of 'An investigation into energy consumption behaviour and lifestyles in UK social housing: improving retrofit delivery and outcomes' and pursued the PhD in Architecture, sustainability at the University of East London. With the intention of promoting health, well-being and energy efficiency in the communities and industries, his research focuses on the optimization of home energy performance in relation to occupants' energy consumption behaviour. After receiving his PhD degree, Wei Shi worked as an architectural designer in the architectural practice until now. He has been involved in assisting and designing a variety of projects in the residential and infrastructure sectors. His insight into energy and environmental impact makes a great contribution to the projects.
