The study investigates apartment’s façade thermal performance with neo-minimalist architectural style in Penang, Malaysia. Neo-minimalist style is considered as the most popular style in Malaysia in 2010s. The style is rediscovering from early modern minimalist movement with a design concept “less is more”. It applies minimal and efficient design of architectural character in defining form and space. Penang Island the second most important city in Malaysia after Kuala Lumpur. It is located at the north-western part of the country. The first case studies is the Light Linear apartment which has sixteen stories located on the east cost of Penang Island at Pantai Street, Penang. The second case study is BayStar apartment building, the eleven stories building tis located in Bayan Lepas at the seaside facing Jerejak Island. In order to conduct this study Fluke Ti20 thermal imager was used to capture thermal images for the west facades of the selected case study hourly from 12:00 to 6:00 pm on 15th March 2017. The study finds that the recessed wall, balconies and the shading devices were the important elements to provide shades on the façades for good thermal performance.

Thermal comfort performance of three vacant naturally ventilated Royal Malaysia Police (RMP) case study lockups (LK1 in Penang, LK2 in Melaka & LK3 in Kuala Lumpur) was measured during monsoon change period from Northeast Monsoon to Southeast Monsoon. According to NGO’s report and previous studies, the lockups condition is very poor and hot which contribute to discomfort among detainees. The objectives of the study are to investigate thermal comfort performance of the lockups based on four environmental parameters (Ta, Tr, Va, & RH) through physical measurement, to predict thermal comfort performance based on operative temperature (To) and neutral operative temperature (Tneutop), and to compare the results with thermal comfort criteria recommended by ASHRAE 55 standard and previous thermal comfort studies in hot and humid climate. The results show that To and Tneutop reading of LK1 is exceeding the maximum range recommended by ASHRAE 55 and previous studies by 2% to 8% (To) and 1% (Tneutop) which categorizing LK1 condition as hot. This is mostly due to high hot airflow brought through an ineffective window opening. The results will be used as reference for improvement towards some aspects such as window opening, building finishes materials, space volume and building orientation in future lockup design.

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.

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.

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.

Due to the different types of courtyards in vertical courtyard system (VCS), their impacts on thermal performance in office buildings may vary. To better understand this issue, this paper investigates the thermal performance impact of three typical vertical courtyards. A field case study was conducted in VCSs during two typical extreme hot days under hot-humid climate conditions. The results show that the vertical courtyards have significant cooling effects under hot-humid climatic conditions. Via testing on linear, integrated, and rooftop courtyard with fusion layout, the fusion one has an obviously positive impact on air temperature reduction (4.3 °C). Compared with the linear and integrated courtyards, the maximum air temperature difference of fusion layout is around 1.6 °C. The thermal radiation environment of the fusion layout was better than that of the other two (linear and integrated). Besides, the surface temperature of the pavements (wood panel) in the vertical courtyards can reach 47 °C, while the vegetation can lower it by 8 °C under the same weather conditions. These findings show that the courtyard with fusion layout is more suitable for extreme hot weather conditions.
