This paper presents the reviews of studies with regards to the development of Green Building Index- Residential New Construction (GBI-RNC). GBI-RNC is considered since the development of Residential Construction is expected to increase every year since Malaysia is considered as a developing country. The Carbon Emission of Residential Construction is evident thus one of the ways to control and commit to Carbon Emission reduction is by promoting Sustainable Development. Even though GBI-RNC has been introduced to the industry since 2009, participation increased just slightly by the year and to reach a rating more than ‘Certified’ are low. Furthermore, a national green rating system is proposed by JKR, to assist with all residential government projects. Therefore, this paper shall present the suggested modifications that should be made to GBI-RNC to improve its elements and gain more influence to maintain as the most used green rating system for residential construction.

This study seeks to measure the temperature difference of 3 types of interlocking bricks and 2 types of conventional bricks, all which are available in Malaysian market. The study aims to assist Malaysia’s residential construction dilemma in masonry. This is done by constructing 5 models using different types of bricks with the same dimensions, finishes and placed in the same area. Six points were taken to measure the temperature differences. The equipment used are 6 Thermocouples and HOBO UX120-014M data logger. Intervals of 15 minutes were recorded with duration of four months in Tronoh, Perak. Results show the best performed brick is IB2, even though IB1 and Clay bricks depict significant temperature differences. Comparing the temperature differences of IB1 and Clay brick, IB1 provide a better performance in a hot weather due to its higher thermal conductivity.
