Investment and Construction Cost Analysis on Net-Zero Energy Building Technology
A research on the concept of the Zero-net-energy buildings, in Sarawak has been conducted. Even though this
technology has been around for almost 10 years, many are still unaware of this technological advancement in the field of
construction. This research paper covers the definition and the operations of a zero-energy building to ensure that a good
understanding of the basis of this zero-energy building is obtained. Even though this type of building will be kinder and
safer to the environment, there are disadvantages to it. Thus, the research includes the advantages and disadvantages of this
technology. The goal of this research is to gain a deeper and further understanding behind this concept. By doing so, this
concept may be applied to improve lives in the future. As for now, one of the closest examples in Kuching is focused on,
namely the Sarawak Energy headquarters building located at the Isthmus. A thorough analysis of the overall building
structure and other necessary aspects such as the power consumption and the cost-effectiveness of this building is conducted.
Other than that, a comparison between in terms of the Building Energy Index (BEI) values, investment analysis and the
construction costs the Sarawak Energy headquarters building along with another building of its kind, the University College
of Technology Sarawak (UCTS) building in Sibu, Sarawak and a conventional building is carried out. Last but not least, a
brief conclusion regarding the topic is drawn at the end of the report.
