Building Information Modelling or BIM has proved its competency in making build construction process effective and efficient. Due to the emergence of more energy efficient approaches and popularity of green certification in building construction, BIM also became a valuable tool to evaluate the building energy performance and sustainability level. Various building typologies using green approaches started to emerge due to the Malaysia Government's sustainability and green policy according to the 2009 National Green Technology Policy (NGTP). Although this development includes green hotels and resorts but there is still lack of quantitative analysis for existing tourism facilities in Malaysia, specifically for green resorts. Thus, this paper describes through literature studies the current BIM development and issues in Malaysia, the green resort certification, and its challenges, as well as the general energy consumption of a hospitality building in Malaysia. By using the BIM-based simulation, this paper is an attempt to investigate the building performance analysis in terms of energy and cost in relation to hospitality industry building design specifically a green resort in Malaysian context. Design alternatives for the existing selected green resort facade were also proposed to further demonstrate the usefulness of BIM simulation to choose the best design option that is energy-cost effective. The conclusion explained the research limitations of the project and indicates the results can be perceived faster by using the simulation as it demonstrated that even the smallest changes can give a positive effect energy-wise and cost-wise which proved that it is beneficial to construct a green resort in the long run.

A kinetic façade, also referred to as a solar responsive façade (SRF), is a movable façade that responds to the amount of light received. The mechanism prevents excessive light from entering while allowing the ideal amount of natural lighting into buildings. Following the green building movement, SRF usage increased because it can both lower heat gain and improve the aesthetics of a building's design. Even though the SRF has many advantages, the façade pattern has become uniform across all cultures, regions, and climates, which results in a lack of identity in building design. This essay will focus on SRF designs that were inspired by Malaysia's Siamese culture. Examining the daylight factor (DF) of three particular Siamese patterns from cultural art, religious art, and cultural craft is the main objective. The designs were then mounted on a wall measuring 5.3 x 6.0 metres with a window-to-wall ratio of 70%. (WWR). Using VELUX Daylight Visualizer 3, the potential Siamese patterns were built as a three-dimensional model and the DF at nine different folding techniques were examined. Based on the percentage of achieving a 1.0 to 3.5 daylight factor in all kinetic folding techniques, the result reveals that the religiously inspired pattern is the best among the three selected Siamese patterns. While the pattern helps to ensure that buildings receive the most natural light possible, the study shows that the folding technique also has a significant impact by reflecting light into the structure.

A substantial amount of daylight is received by tropical countries like Malaysia. There are advantages and disadvantages to using this renewable resource in a high-rise office building. Such buildings' deep plan spaces make it difficult to create a uniform daylight distribution across the space. A solution for this issue is the usage of an integrated Venetian blind (VB) with a horizontal light pipe (LP). Using an overcast and intermediate sky in South orientation, seven (7) distinct types of VB angle configurations were simulated using the Integrated Environment Solution Virtual Environment (IESVE) to evaluate how well they performed in daylight with an integrated LP. The findings demonstrated that the daylight uniformity throughout the room was improved by the integration of the VB and LP systems. When compared to a room with only a LP installed, VB with 0o and -15o angles had the best performance. The combination of LP and VB allowed for the shading of the front portion of the space and at the same time, illuminating the rear portion of the space. The results of this study encourage building designers to utilise the integrated VB and LP in the deep open-plan high-rise office building and reduce the use of non-renewable energy resources.

The paper aims to discuss the role of architects in the evolution of three main formal administrative architectures in Malaysia. All these three chosen case studies housed the main seat of the government of the era. The main concern is to outline the evolution of the administrative architecture in Malaysia through understanding the factors that may influence the production of these national buildings. A case study approach as defined by Yin (2011) was applied by using interpretivist approach in order to understand the factors that may have influenced the design of these prominent administrative architecture in Malaysia. The research shows there is a significant tie between the architect as part of the decision-maker and the design of the administrative building, making the selection of the architects for the purpose of building an important national architecture very important. To date, the research on the administration building in Malaysia focuses on design aspects, and none discussed the relationship between the administrative buildings with the architects’ background with reference to societal conditions. The research is of value for clients as patrons of national projects to understand the syntax of ‘administrative architecture’ as these buildings are deemed as meaningful national symbols.

Vertical Greenery System (VGS) is one of the passive solutions for urban greening that emphasizes application of building envelope. It can improve both indoor thermal performance and energy efficiency in the longer run. To realize this effort, proper orientations are identified as the main key factors. As high-rise buildings are being develop throughout urban cities in Malaysia, indoor spaces received high amount of solar radiation due to improper orientation and site constraint exposure that mainly comes from East and West. To overcome this issues, orientation study and vertical percentage analysis were conducted in this paper. Investigation on the importance of having proper façade orientation and greenery percentage in urban cities are the main purpose of this research. Several methods that involved empirical studies and simulation using IESVE software were conducted to fulfil this investigation. Based on the findings, the highest reduction in both temperature and cooling load energy using vertical greenery system can be tabulated in the following order: East > West > South > North. It is suggested, that both the East and West orientations to be the best façades to implement the VGS. Both facades received direct sunlight in the morning and evening sessions, enabling the VGS envelope to reduce the indoor dry bulb temperature and building cooling load energy more efficiently at higher altitude. For vertical greenery percentage analysis, higher percentage of vegetation will result in a more positive effect towards the reduction of indoor dry bulb temperature. In conclusion, the incorporation of a 100% VGS window wall ratio coverage is shown to have a reduction of 1.42°C and it was estimated at least 16.9% for building cooling load energy saving.
In single-aspect studio apartments, daylight sufficiency and sunlight exposure constrain window design simultaneously. A studio reference room in Bangkok, Thailand was evaluated using Radiance through Ladybug Tools and a TMYx weather file. Six main-window configurations, three visible-light transmittance (VLT) levels (0.45, 0.65, 0.88), and four orientations formed a complete factorial set of 72 cases, assessed with spatial daylight autonomy (sDA300/50%), useful daylight illuminance (UDI100–3000), and annual sunlight exposure (ASE1000,250). The room was also simulated with the balcony door alone, giving a simulated baseline. Within the investigated design space, orientation accounted for 93.16% of the variation in ASE and 63.36% in UDI, but only 3.39% in sDA, which was governed instead by VLT (69.10%) and window configuration (23.23%). sDA ranged from 52.17% to 100.00% and 19 cases did not reach 75%; ASE ranged from 1.09% to 53.26%. The door alone gave a mean sDA of 47.10%, and the smallest window raised it by 25.00 percentage points. A screening rule informed by LEED v5 retained 29 cases and no west-facing case; substituting finer-grid values for four near-threshold cases reduced this to 28, testing that subset rather than grid independence across the dataset. Orientation and solar exposure should be assessed first, transmittance second, and window area last.
