Abstract

Three residential colleges located in a university campus at the capital city of Kuala Lumpur and built in different decades were selected for landscape studies with respect to species and position of the trees, as well as the effects of the current landscapes as a shelter in reducing solar radiation on buildings, as a pre-assessment for the Low Carbon Cities Framework (LCCF) and assessment system. These landscape designs were carefully studied through on-site observation. The name and location of the matured plants were redrawn and visualised with standard normal photographs. The studies revealed that the old residential college landscape is dominated by tropical forest trees which are able to provide a significant shade to the buildings and offered a potential to achieve sustainable development due to a higher rate of carbon sequestration. While, palm and hybrid fruit plants were most extensively cultivated in the landscape of new residential colleges due to low maintenance and being fast growing.

Abstract

Purpose

The purpose of this paper is to present the efficiency of electricity use and potential of electricity reduction at 12 residential colleges located at University of Malaya Campus, Kuala Lumpur.

Design/methodology/approach

The work presented applies an energy audit when energy consumption data were collected and analysed for a five‐year period. The total savings of electricity used at residential colleges were identified through the difference between average total energy use in a year (kWh) and minimum electricity usage.

Findings

The study finds that residential colleges with special features of building layout and arrangement performed better with regard to electricity consumption due to the prior group's superior utilisation of day lighting and natural ventilation. The floor area of the rooms, volume, density, enclosure and facade design, including window design, window area, and window‐to‐wall ratio also influenced the total electricity usage of the residential college buildings. Also, through adaptation of the corridor area to include more natural ventilation and daylight, approximately 40 to 90 percent of average electricity usage could be conserved in a year.

Research limitations/implications

The methodology is limited to energy audit for a five‐year period of metered data and walk‐through analysis.

Practical implications

The findings raised some issues related to thermal comfort of the residents.

Originality/value

The study can be used as baseline data for a tropical region particularly on current electricity usage and potential of energy conservation in residential building.
