More than half of the energy consumption in buildings is utilized for heating and/or cooling indoor environment. The building envelope plays a key role controlling effects external weather and, therefore, linked with many passive design strategies. Thermal storage (TES) and phase change materials (PCMs) are efficient techniques, which can store high density thermal energy. PCMs attract researchers to implement them components management. In walls, they were implemented different positions...
Phase change materials (PCM) are widely known for their high thermal storage capabilities. They generally utilized to increase the mass of buildings' lightweight materials, which improves performance and reduces need air-conditioning systems. PCM layers commonly applied interior parts, close indoor environment, helps regulate temperature. However, few studies reported that application on exterior envelopes increases insulation, can reduce outdoor heat gain. Therefore, this study aims develop...
Rapid urbanization and population growth have intensified global energy demand, with fossil fuel consumption aggravating air pollution climate change. Hydrogen, a clean carrier, is essential for transitioning to low-carbon economy. This study examines the color-coded classification of hydrogen production pathways, derived from both renewable non-renewable sources, their emission profiles. Additionally, it delves into critical aspects storage transportation, highlighting need robust...
A hot-humid climate, which is characterized by uniform diurnal temperature throughout the year, can provide a year-round opportunity to benefit from phase change materials (PCMs) for buildings' application. However, small fluctuation might restrict PCMs' performance and efficiency. This paper investigates capability of PCMs decrease peak indoor air (Tᵢ) naturally conditioned buildings in climate region storing night coolness. To this end, field measurement has been conducted existing...
Building sector is associated with high energy consumption and greenhouse gas emissions, which contribute to climate change. Sustainable development emphasizes any actions reduce change its effect. In Malaysia, half of the utilized in buildings goes towards building cooling. Thermal comfort studies adaptive thermal models reflect temperatures for Malaysians naturally conditioned buildings, make it possible tackle difference between buildings’ indoor temperature required by using proper...
This study evaluates the envelope thermal performance of high-rise apartment buildings in Malaysia, which are being largely dominated due to high economic development and increased population. The evaluation was conducted using Overall Thermal Transfer Value (OTTV), is key tool used Green Building Index assess Energy Efficiency buildings. Different were selected with different architecture styles, account for several periods building construction. OTTV value calculated west-oriented façade...
Buildings account for nearly 50% of the total energy consumption. The use air-conditioning is one major influencers to high consumption in buildings. To tackle this consumption, buildings are required be more efficient. This study aimed investigate retrofitting existing residential building efficiency by using Overall Thermal Transfer Value (OTTV) as an assessment tool. Various measures were involved, including varying colour opaque wall with different solar absorptivity, U-value and shading...
Thermal comfort is a mean of being satisfied with the thermal environment. A study was conducted in field to assess perception for residents naturally ventilated residential building Malaysia. The objective this find out whether are thermally comfortable buildings without use air-conditionings. result showed that generally (i.e. comfortable) environment, even though their sensation outside central three categories ASHRAE standard, which reflects acclimatization local hot and humid climate.
This paper focuses on the daylight distribution pattern in light well high rise residential buildings Penang, Malaysia.Light is a vertical void through all of floors building which designed to distribute adjacent spaces.The size determined by UBBL or Malaysian Uniform Building By Laws (1984) clause no 40.The suitability questioned when original 8 storey 1980s have risen up 40 storeys after year 2000.Eight case study varied heights and sizes were carried out natural illumination data taken at...
Adaptive theory of thermal comfort suggests that people tend to adjust themselves or their environment achieve thermally comfortable conditions whenever discomfort occurred. In this work, a high-rise residential building was selected investigate the residents’ adaptive behaviour in hot humid climate Malaysia. The objectives are preference use available opportunities comfort, daily climatic controls and reasons influence usage. A questionnaire survey distributed personal adjustment as well...
As we spend most of our time in indoor spaces, half the energy consumption buildings is used to improve thermal environment achieve thermally comfortable conditions. However, studies showed that people naturally ventilated have a broader comfort zone. Additionally, hot areas can tolerate higher temperatures. Therefore, this work investigates and evaluates level conditioned buildings. Field measurements were conducted various residential spaces different The calculate operative temperature...
Thermal comfort is the individual satisfaction with surrounding thermal environment. It mainly affected by environmental factors (i.e., air temperature, relative humidity, movement, and mean radiant temperature) activity clothing). However, other such as acclimatization, experiences expectations, food drink, body shape subcutaneous fat, age gender, state of health might play a significant role in sensation This study investigates possible differences perception between local foreign...
