With the emergence and rapid deployment of PV (photovoltaic) façades, a comparison among see-through amorphous silicon (a-Si) PV glazings and traditional glazings under different architectural conditions could provide us a broader perspective for comprehending the energy performance and...

Effectiveness of SEHRAC (storage-enhanced heat recovery room air-conditioner) for water heating in residential buildings in Hong Kong and elsewhere has been confirmed in previous studies. However, given these studies assumed a theoretical maximum recoverable heat, whether its use is still energy...

Benchmarking the energy performance for cooling purposes in buildings is an important tool for energy management. This paper proposes a novel index and develops a benchmarking process for energy performance for cooling purposes by means of data envelopment analysis and cooling degree hour...

Traditional methods of evaluating energy performance of building tend to focus on comparing the observed energy consumption with the average value of energy consumption by regression method or theoretical value calculated by simulation analysis. For evaluating and ranking the energy performance...

Benchmarking has been recognized to be an effective analysis methodology and management tool that helps to improve efficiency and performance in many areas for different objectives. Industrial energy benchmarking is a process of evaluating energy performance of an individual industrial plant or...

Improving energy performance of buildings has become a key goal in managing energy demand. In this context, Europe produced the Energy Performance of Buildings Directive (EPBD). Flanders (Belgium) converted this directive into the ‘Energy Performance and Interior Climate’ (EPB). Taking into...

Energy consumption of buildings takes up about a third of Singapore's total electricity production. In this paper, we present a pioneering study to investigate the energy performance of residential buildings. Beginning with an energy survey of households, we established the air-conditioning...

The study assesses the environmental sustainability of palm biodiesel production systems in Thailand by focusing on their energy efficiency and environmental impact potentials. The Net Energy Balance (NEB) and Renewability indicate energy gain for palm biodiesel and its co-products as compared...

Identifying the building parameters that significantly impact energy performance is an important step for enabling the reduction of the heating and cooling energy loads of apartment buildings in the design stage. Implementing passive design techniques for these buildings is not a simple task in...

Energy retrofit measures (ERMs) are applied to reduce the energy consumption of buildings. The effectiveness of any ERM depends on many building specific factors, such as location, size, operation, building envelope, electrical, heating, cooling and ventilation system properties. It is common...
