Novel methods are sought to provide greater efficiency of the installation of ground heat exchangers for GSHPs (ground source heat pumps) in domestic buildings. An economically viable option is to utilise concrete foundation piles as ground heat exchangers. The objective of this study is to...

Fuel cells produce heat when generating electricity, thus they are of particular interest for combined heat and power (CHP) and combined cooling heat and power (CCHP) applications, also known as tri-generation systems. CHP and tri-generation systems offer high energy conversion efficiency and...

This study regards the performance prediction of concentrating photovoltaic (PV) modules. For a solar concentrator aperture area of 1 m-super-2, the efficiency and power output of a concentrating PV module is calculated for various temperatures and concentration ratios. The study is then...

This paper analysed the dynamic performance of a novel dew point evaporative cooling for air conditioning of buildings in the UK regions. The issues involved include analyses of the UK weather conditions, investigation of availability of water for dew point cooling, and assessment of cooling...

Photovoltaic/thermal (PV/T) technology developed quickly in recent years with new configuration designs and methods for energy efficiency improvement. This paper presents a review of the development of PV/T technology, mainly focusing on the past 5 years, including commercial PV material...

The advantages of numerical modelling compared with experimental studies (e.g. reduced cost, easy control of the variables, high yield etc.) are well known. Theoretical studies where experimental validation is also presented provide an important added value to numerical investigations. In the...

Solar energy and wind energy are two main renewable energy sources. Concentration of solar energy onto a smaller area may reduce the cost of PV modules and achieve high efficiency. On the other hand, wind augmentation allows lower trigger wind speed besides the reduced wind turbine size. For...
