Past Research

Integration of Passive Ventilation and Novel Cooling Systems for Reducing Air Conditioning Loads in Buildings, Qatar National Research Fund 3rd Cycle, NPRP 09-138-2-059, $1,050,000, Named Researcher

This research focused on the development of a passive cooling wind tower with heat pipe material for the reduction of energy in built environment. I've utilised different methodologies such as Computational Fluid Dynamics (CFD) modelling, Building Energy Modelling (BEM) and wind tunnel experimental methods to develop and investigate a novel prototype. I've tested and patented the technology (WO2015/087035) during the final stages of my doctorate.

Prototype development and field tests of passive cooling wind towers, University of Leeds and the IP Group, £36,000, Co-I

Design and specification of natural ventilation for Shaikh Khalifa Bin Zayed Bangladeshi Islamia School. Zayed Future Energy Prize, June 2014, £5,000, co-PI

A multi-directional type cooling wind tower was installed in a school building in the Middle East to conduct post occupancy evaluation. This research project was supported by the Zayed Future Energy Prize.

Development of a passive dehumidification technology, EPSRC Impact Acceleration Account, £36,000, Co-I

Rotary desiccant wheels are used to regulate the relative humidity of airstreams. These are commonly integrated into Heating, Ventilation and Air-Conditioning units to reduce the relative humidity of incoming ventilation air. To maximise the surface area, desiccant materials are arranged in a honeycomb matrix structure which results in a high pressure drop across the device requiring fans and blowers to provide adequate ventilation. This restricts the use of rotary desiccant wheels to mechanical ventilation systems. Passive ventilation systems are able to deliver adequate ventilation air but cannot control the humidity of the incoming air. To overcome this, the traditional honeycomb matrix structure of rotary desiccant wheels was redesigned to maintain a pressure drop value below 2 Pa, which is required for passive ventilation purposes. In addition to this, the temperature of the regeneration air for desorption was lowered. Radial blades extending out from the centre of a wheel to the circumference were coated in silica gel particles to form a rotary desiccant wheel (Patent GB1506768.9).

Thermal Comfort of Spectators and Players in Qatari Stadiums, Qatar National Research Fund 6th Cycle, NPRP 6-461-2-188, $1,048,000, Named Researcher

This research focused on the development of low-energy cooling strategies for the upcoming 2022 FIFA World Cup for reducing the energy consumption whilst maintaining thermal comfort. The overall aim of the project was to advance knowledge in the area of cost effective thermal comfort in stadiums and sporting arenas using cutting edge computational simulation, wind tunnel tests and field experiments to optimise performance of existing and emerging low energy building services technologies to minimise the energy consumption impact of new Qatari stadiums. Hence, emitting less CO2 to the atmosphere to conserve energy resources, preserve the local environment, meet the country's FIFA obligation and improve the quality of life.

Low-energy Harvesting for Smarter Cities (2016-present)

In this modern age low-energy devices are pervasive especially when considering their applications in the built-environment. The multitude of low-energy applications extend from wireless sensors, radio-frequency transceivers, charging devices, cameras and other small-scale electronic devices. The energy consumptions of these devices range in the milliwatt and microwatt scale which is a result of continuous development of these technologies. Thus, renewable wind energy harnessed from the aeroelastic, triboelectric and peizoelectic effect can play a pivotal role in providing sufficient power for extended operation with little or no battery replacement.

Urban Integrated Solar Pavements (2015-present)

Pavements tend to absorb the heat of the sun up to the point when they radiate heat as quickly as they are absorbing it: the surface temperature of pavements in direct sunlight can often reach up to 15°C higher than the ambient air temperature. Solar pavements heat using fluid circulating through an array of pipes embedded in the surface of the road and deposits it in storage constructed beneath the insulated foundation of buildings. This project investigates the performance of an urban-integrated solar pavement system by using numerical simulations.

Advance Personal Comfort System in Offices (2016-present)

This project aims to improve user comfort and satisfaction regarding the thermal environment in the open plan office, which is a current challenge in the workplace addressed by limited research. The main difficulty in an open plan setting is that changing the room temperature in an area affects all occupants seated nearby. This issue in addition to individual differences in perceiving the thermal environment create a great challenge to satisfy all occupants in the workplace. This study investigates the application of an advanced thermal system, which allows individual control over their immediate thermal environment without affecting the thermal environment and comfort of other occupants.
