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.

Daylight performance in a velodrome cycling track arena is essential to create splendid scenery for the athlete to perform during the event held. Therefore, a moveable kinetic roof according to the sunlight path on top of the building is important to implement. A specific requirement for cycling track is to avoid any shadow from the cyclist to steer clear any incident from happening during the game begins. The new technology of kinetic roof that integrate creativity with the sun movement would help to control the amount of sunlight that will enter the indoor area. The integration of kinetic roof to be placed at the top of the sports indoor arena would help to reduce the electricity consumption for that building as it integrates to control the amount of light to pass through into the private area. This study is divided into two parts; the analysis on the preference of local velodrome in Malaysia, which is in Nilai, Negeri Sembilan and 3D model daylight analysis using VELUX. Based on the analysis, the implementation of the kinetic roof in velodrome design in Malaysia will be able to let the required amount of daylight appear for the internal area. While passive skylight that integrated at the current velodrome was not capable of controlling the daylight and it is dependable on the weather condition.

Since 2019, the Coronavirus infection has substantially impacted the worldwide ecosystem. This disease has apparently become airborne and has spread globally. Most daily activities have been curtailed to prevent the spread of the disease. Several measures have been devised by the World Health Organization to control the transmission of disease among humans. However, interior spaces are also crucial because individuals spend most of their time inside. To improve the interior living environment, it is necessary to develop a way to prevent the spread of airborne diseases. To obtain the desired level of efficiency and the requisite level of health for people to stay indoors, it is essential to install an efficient ventilation system. To avoid the transmission of airborne infections in confined areas, the purpose of this work is to examine the impact of the filtering mechanism in a controlled environment provided by Heating, Ventilation, and Air Conditioning (HVAC) systems. According to the study, ventilation, along with MERV13 or above recirculating filters, for instance, must be used (High-Efficiency Particulate Air) This criterion can be met with HEPA or a combination of outside air, filtration, and air-cleaning technology. To reduce the transmission of airborne diseases, the outcome of the study will result in a more effective installation of the mechanism of HVAC systems in interior environments.

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.

Vertical Greenery System (VGS) is a passive thermal strategy in urban high-rise which implements vegetation in front of building facades. The purpose of having VGS is to absorb heat gain due to urban heat island that affects the outdoor and also indoor environment. This paper investigates the possibility of having greenery on residential balcony in order to improve the internal thermal performance and minimize electricity consumption. Due to increasing usage of air conditioning system (A/C) during nighttime, this paper will focus on the effects of using VGS using simulation of test rooms on ground level and 8th storey level located in Putra Place Condominium Penang. This paper presents an extended series of night-time simulation data from the use of VGS. The findings are based on the use of Integrated Environmental Solutions Software (IESVE) and are validated using existing measured data. The results of VGS application will compare the indoor thermal performance between a control room (without vegetation) and VGS room (with vegetation).Overall, it supports the fact that having vegetation on high rise level will significantly minimize the indoor air temperature (DBT) more effective when compared to ground level application. The night-time study showed that the wall surface with VGS absorbed less and emits even less heat gain into the internal spaces. Therefore, having vegetation as passive shading strategy will increase the building efficiency and eventually reduce air conditioning system usage.
