Using portfolio analysis and individual detailed case studies, we studied the energy performance and drivers of energy use in 51 high-performance office buildings in the U.S., Europe, China, and other parts of Asia. Portfolio analyses revealed that actual site energy use intensity (EUI) of the...

Building performance can be expressed by different indicators such as primary energy use, environmental load and/or the indoor environmental quality and a building performance simulation can provide the decision maker with a quantitative measure of the extent to which an integrated design...

This paper presents an efficient design tool for the estimation of the transient electromagnetic peak torque and transient rotor over-voltages of wind turbines (WT) doubly-fed induction generators (DFIG) during severe fault conditions on the grid side. This versatile and robust tool is well...

The advanced buildings of tomorrow will need to take advantage of renewable, ambient and waste energy to approach ultra-low energy buildings. Such buildings will need to consider Thermal Energy Storage (TES) techniques customized for smaller loads.

In this study, the technical effectiveness of solar cooling and heating was investigated for typical low-rise residential building in the subtropical Hong Kong. Since water heating was required for domestic hot water supply rather than space heating, a separate or an integrated provision of...
