With some recent developments, the zero energy building and near zero energy building has gained a worldwide attention and now it is seen as the future building concept. Since such buildings are now the center of attraction, various advancements in this area are being reported. This paper is a detailed review of the literature on the zero (or near zero) energy building (ZEB) envelope components...

This study focuses on the impact of school building design factors on winter extra energy consumption which mainly includes space heating, water heating and other appliances related to winter indoor thermal conditions. A number of Auckland schools were randomly selected for the study which introduces a method of using real monthly energy consumption data for a year to calculate winter extra ene...

Interoperability issues have been well acknowledged as an impediment to improve productivity in the Architecture, Engineering and Construction (AEC) industry. The current information exchange from building design to building energy modeling has numerous problems, including object parametric information deficiencies, geometric misrepresentations and re-input data confusion. These problems lead t...

In Sweden, all new buildings need to comply with the National Board of Housing, Building and Planning’s requirement on specific purchased energy (kWh/m2). Accordingly, this indicator is often used to set design criteria in the building procurement process. However, when energy use is measured in finished buildings, the measurements often deviate significantly from the design calculations. The m...

The gap between the intended and actual energy performance of buildings is increasingly well documented in the non-domestic building sector. Recognition of this issue has led to the availability of a large range of initiatives that seek to ensure energy efficient building operation. This article reviews the practical implementation of three such initiatives in a case study building at the Unive...
