The influence of courtyard on the thermal performance of Development Department office building in University Malaysia Perlis (UniMAP, Pauh Putra campus) is investigated through simulation study for the effect of ventilation on indoor air temperature and relative humidity of the building. The study is carried out using EnergyPlus simulator interface within OpenStudio and SketchUp plug in software to measure both of air temperature and relative humidity hourly on 21 April 2017 as a design day. The results show that the ventilation through the windows facing the courtyard has sufficient effect on reducing the air temperature compared to the ventilation through external windows since natural ventilation is highly effective on driving the indoor warm air out to courtyard. In addition, the relative humidity is reduced due to ventilation since the courtyard has high ability to remove or dilute indoor airborne pollutants coming from indoor sources. This indicates that the presence of courtyard is highly influential on thermal performance of the building.

Past years have witnessed the popularity of traditional Malay house as a common housing type in Malaysia. However, double-storey house has become one of the common types of low-rise housing in Malaysia. Several passive cooling strategies have been adopted to cope with the hot-humid climate of Malaysia. In this study, the thermal comfort of a double-storey house was examined when different passive cooling strategies that were adopted from traditional Malay houses were applied using IES-VE 2019 building simulation software. The simulation was conducted for various design strategies such as changing concrete roof tiles to clay roof tiles, adding two small openings to the attic, removing the ceiling between the upper floor and the attic, and extending the overhang by 50% of its length for all the four facades. All these strategies were tested and compared between full-day natural ventilation and without any ventilation. The thermal comfort of these strategies was graphically defined based on the operative temperature. These analyses revealed that protecting the building envelope by extending the overhang by 50% of its length for all the four facades could ensure the best thermal comfort is achieved compared to other selected strategies. Recommendations for further studies are also outlined in this paper.

In building design, architects actively utilize all kinds of methods, such as ventilation and sunshade, to adapt to the hot-humid climate ,which is the main way to create a “green building ”.This paper describes the “climate adaptability ”design tactics in the case of the University Library in the Lingnan region——in a hot-humid climate. Furthermore, this paper gives suggestions by describing the advantages and disadvantages of the typical design practice in order to benefit regional architectural study.

Using building information modeling (BIM) and Ecotect, this paper estimated carbon emissions during an office building’s life cycle. This building’s life cycle CO2emissions were divided into three parts: the construction, operation, and demolition stages. Among these, the statistics on the schedule of quantities were generated using BIM, and the energy consumption during the building’s operational stage was obtained using ECOTECT simulation. Sensitivity analysis was performed by changing several alternative parameters, to identify which parameter has more impacts on building performance. The paper demonstrated that (1) BIM and Ecotect are very helpful in estimating carbon emissions from a building’s life cycle, (2) the primary and effective measures to reduce the building’s CO2emissions in hot and humid climate should be arranged as follows: (a) within the limits of comfort, reducing the fresh air volume; (b) extending the indoor temperature range; (c) improving the thermal insulation performance of exterior windows, walls, and roofs; (d) exploiting natural ventilation during transition seasons, and (3) currently there are some limitations in performing LCA based on BIM and Ecotect.

Odour Removal

In buildings, natural ventilation is for human comfort; for odour removal, body and the structure cooling. A previous study revealed that libraries in Nigeria could not function efficiently without artificial ventilation and lighting. Artificial ventilation, aside from economic disadvantages, it is not reliable and anti-sustainability while natural ventilation is reliable, consume less energy, and in other words, it is more efficient when compared with other types of ventilation. The research evaluates the application of passive architectural strategies for natural ventilation in libraries within the hot-humid climate of Nigeria, intending to recommend natural ventilation strategies in libraries. Ten (10) libraries were selected randomly in the study area from both institutional and public libraries. The research conducted using observation schedule, the variables in the research are; Window types, Clerestory windows availability, Door openings, Screen walls, Courtyard, Other openings, use of external shading devices and orientation of the library. The data analysed using descriptive statistic; the results presented using tables, bar charts and pie charts. The research revealed that 29% of the cases studied use external vertical structural shading devices, 36% use horizontal shading devices, 21% use both vertical and horizontal shading devices to deflect solar radiation and 14% do not use any external shading devices. 80% of the libraries studied was oriented toward north-south (NS) direction, while 20% oriented toward east-west (EW) direction. Therefore, the majority of the libraries studied have desired orientation; however, each lacks one of the passive cooling strategies. Adequate natural ventilation in the libraries is achievable by the proper synthesis of the building orientation, proper design of building internal spaces, the proper position of window openings and use of projected window as well as clearstory. More so, further study to enhance natural ventilation configuration for the study area is desirable.
