This paper reports the investigation results of the energy payback time (EPBT) and greenhouse-gas payback time (GPBT) of a rooftop BIPV system (grid-connected) in Hong Kong to measure its sustainability. The 22 kWp PV array is facing south with inclined angle of 22.5°. The hourly solar...

In order to help water supply utilities improve water supply management, offer early warning and control water pipeline leakage, so as to provide clean water to residents, many instruments are installed to monitor hydraulic and water quality conditions along the water pipelines. However, one of...

In this report, a novel magnetic levitated bearing suitable for Vertical Axis Wind Turbines (VAWT) is introduced, fabricated and tested. The bearing system generates a magnetic force, which can support the weight of the wind turbine rotor. A Finite Element Method (FEM) simulation shows how low...

In metropolitan cities like Hong Kong where land value is high, highrise commercial and residential buildings with “central core” design are developed. The lift lobbies in the buildings are usually located in the centre of the building to free up peripheral areas to provide valuable exterior...

Due to criticisms of potential identification issues within spatial panel data models, this study contributes to the literature by comparing forecasts of province-level carbon dioxide emissions against empirical reality using dynamic, spatial panel data models with and without fixed effects....

Oversized equipment is one of the key factors for poor energy performance of commercial buildings in Hong Kong. Similar situations exist also in many buildings in different parts of the world. The use of realistic design criteria has been identified as an effective method to reduce the equipment...

Voluntary building assessment schemes have emerged worldwide to help assess the environmental performance of buildings. As building environmental assessment is a rapidly evolving field, the scope and details of such assessment schemes are continuously undergoing updating and refinement....

Photovoltaic farms in Malaysia are being developed tremendously as a form of supporting fossil fuel setbacks in Malaysia power generation. An important parameter of the PV installation is the power (Watts) accumulated over sunlight retrieval. Considerable losses may arise from the conversion,...
