Kuala Lumpur, as a major capital city, has undergone a drastic transformation in the past ten years. Many heritage buildings have been sacrificed for urban renewal projects. Those located in the touristic heritage zones within Kuala Lumpur were being converted by their owners into hotels and cafés to meet current demands to sustain their incomes. This approach, however, creates several physical and environmental issues within the new adaptation. The aim of this study is to evaluate the building performance of heritage shophouses that were adapted into budget hotels. The research focuses on two case studies in a strategic and historical location of Jalan Sultan, Kuala Lumpur. At the initial stage, interviews and physical surveys were done to determine the context of this study. The authors of this research then used a triangulation method through indoor environmental condition assessment, measurements of indoor environmental conditions and occupant survey to determine the indoor building performance after the adaption. Results showed that adaptive reuse heritage buildings can perform and meet new indoor environmental requirements, but many sensitive design judgments need to be made before the adaptive reuse renovation. The research found that the use of natural light, natural ventilation, recycled materials and water efficiency have been neglected and thus, they should be prioritized and preserved to ensure a successful change of use. Conserving existing heritage buildings, while incorporating new usages with acceptable comfort, is in line with the principle of sustainability.

The increasing global concerns about the environmental degradation and climate changes oblige architecture students to apply sustainable design approaches in their studio projects. Therefore, renewable energy raises the expectation of providing sustainable solutions for their architectural design proposals. This paper aims to investigate the learning of students in knowledge, awareness and applicability on sustainability during their first three years of the part 1 architecture programme. Surveys were conducted on 500 students from eight architecture schools from the local universities, two architecture schools from the polytechnic colleges and three architectural schools from the overseas universities. These survey results from 335 respondents confirmed that the learning on sustainability through self (51.6%), peer (48.6%) and design studio lecturers (37.0%). These results confirmed also that most respondents did rely on pre-design assessments to develop sustainable design strategies in their final architectural design proposals. These results concluded that the perception of architecture students on learning sustainability is based mainly on other sources. These findings provide knowledge for educationists and practitioners towards the planning of architecture curriculum and the implementation of pedagogical approach in sustainability. This paper determines the most important source of learning on sustainability knowledge for students in the pedagogy at university level.

The relation between indoor environmental quality (IEQ) and occupants comfort has become a critical area of research through building life cycle. The importance of the relationship becomes highlighted when IEQ has a strong influence to change people behaviour through its nature specifically in places like an office building where the productivity of occupants remains at the top of everything. In this regard, this manuscript documented the parameters of the indoor environment quality which has a strong influence on occupants' comfort. Through critical review of literature, it has been found that IEQ parameters as thermal, noise, light and air quality could strongly affect the human comfort and health while having a critical role in energy consumption in the building. Moreover, there is a complicated relation among IEQ parameters which make it difficult for a designer to find a balance among them regarding occupants' comfort and productivity and this complication is more confusing in green construction. Many post occupancy evaluation (POE) studies in both conventional and green buildings have carried out, but almost none of them indicated a full satisfaction with IEQ parameters simultaneously. Therefore, this paper investigated among IEQ parameters and their correlation with each other pertaining to occupants' satisfaction, health and productivity in office buildings with different methods of construction.
