To investigate and demonstrate the effectiveness of applications of available environmentfriendly technologies in buildings in Hong Kong, a number of eco-building concepts are used on a small building in the Kadoorie Farm and Botanic Garden in Hong Kong including 4 kW photovoltaic-roof, roof...

This paper presents a set of indoor and outdoor measurement methods and procedures to determine the empirical coefficients of the Sandia Array Performance Model (SAPM) for a semi-transparent amorphous silicon (a-Si) PV module. After determining and inputting the total 39 parameters into the...

This paper aims to examine the sustainability and environmental performance of PV-based electricity generation systems by conducting a thorough review of the life cycle assessment (LCA) studies of five common photovoltaic (PV) systems, i.e., mono-crystalline (mono-Si), multi-crystalline...

The intermittent characteristic of a solar-alone or a wind-alone power generation system prevents the standalone renewable energy system from being fully reliable without suitable energy storage capability. In this study, the most traditional and mature storage technology, pumped hydro storage...

This paper presents a detailed feasibility study and techno-economic evaluation of a standalone hybrid solar–wind system with battery energy storage for a remote island. The solar radiation and wind data on this island in 2009 was recorded for this study. The HOMER software was employed to do...

Climate change may seriously affect the energy consumption of buildings by influencing their air conditioning loads, especially the ventilation loads which vary directly with the local weather conditions. Research on how the ventilation load responds to climate change is of great significance,...

The shading-type BIPV claddings can act as power generators as well as external shading devices and insulation panels. There is little available information about the impacts of orientations and inclinations on the combined energy effects of the shading-type BIPV claddings, including the power...

The falling film liquid desiccant air conditioning system is promising to achieve a low pressure drop and low possibility of solution droplets carried by air. However, the insufficient wetted area was found by previous researchers, and its value is difficult to be determined. With a single...

This paper studied the annual thermal performance of a photovoltaic wall (PV wall) mounted on a multi-layer façade. Based on some developed unsteady-state heat transfer models for a PV wall and a normal wall, the annual thermal performance of two types of walls was simulated. Compared with a...

Currently one of the most promising power solutions for remote rural areas and isolated islands which are far away from utility grid is the stand-alone solar photovoltaic (PV) renewable energy system or hybrid solar–wind power system. This paper presents the investigation results of a real...
