Abstract

Drastic transformation in the construction industry is required to achieve global net-zero targets while accommodating the continuing need to build to anticipate the growing population. With the increase implementation of energy efficient building, the significant of embodied carbon becomes higher. The use of biomaterial has great potential to reduce building emissions. This paper presents a case study that has been built with engineered timber components, and examines to what extent, a further reduction of embodied emissions can be performed. Three material replacements were proposed to further decarbonize the building emissions, and the embodied carbon reductions resulted by changing the timber specification and fly ash use in concrete mixture were assessed quantitatively with embodied carbon assessment. Results show that by replacing the building materials with lower carbon options, the embodied carbon of the case study can be reduced from 52 to 242 tons of CO2e or 2.82 to 12,99 kgCO2e/m2.

Abstract

Vertical housings have been developed to solve housing quality degradation due to rapid urbanization. These housings are often lack of privacy and comfort, since the lay-out mostly consists of one open plan space with limited area. This paper presents a lightweight and multi-purpose partition to improve the living quality in vertical housings. The lightweight characteristic is intended to minimize structural loads, while the multi-purpose property allows the partition to be transformed into some furniture for spatial efficiency. A literature review and material surveys were performed prior to material selection and the design process. Then, physical model experiments were carried out to simulate the installation process and the transformation process of the partition modules into some furniture. Result show that the partition’s weight is only 11-36.7% of the common partition wall, and when installed, the transformable property enables an adaptable space which can be adjusted to the occupants’ different conditions.
