“…Although there are some review articles that holistically address the factors that impact cooling demands, such as [13] and [14], they lack specific aspects. Chen et al [13] presented a review article about the internal and external influencing factors.…”

“…However, reporting energy savings in terms of cooling demand and loads may be more significant and provide a more accurate picture of the true contribution of cooling demand to overall energy consumption. Also, Anaya et al [14] concluded that building envelope parameters are one of the most influencing factors on cooling loads, but they did not address the specific envelope parameters within cooling loads since the building envelope involves a considerable number of parameters that vary in their influence, such as glass characteristics, wall insulation, etc. Furthermore, their review is limited to high-rise buildings, in which a building exceeds 23 m only with no consideration of low-rise buildings.…”

Energy consumption in buildings is considerably high in areas of hot and humid climates due to its association with high cooling loads. Electricity grids are highly affected by the consumption of cooling systems like air-conditioning and large refrigeration facilities, which significantly impact the economic and environmental sectors. As building design and operating parameters influence the cooling demand in the building, it is believed the root cause of the problem may be detected at an early building design stage. Thus, this review identifies the building design parameters that impact the cooling loads in buildings that are geographically restricted to countries with hot and humid climates. The building's design characteristics are classified into four main categories: glass characteristics, wall characteristics, building orientation and dimensions (BO & D), and building cooling system. The review was conducted over high-rise and low-rise buildings. Annual energy requirements (in some cases overlapping with electricity consumption), annual cooling loads, and peak cooling loads are the three forms in which energy demand reductions in buildings are represented. It is found that maximum annual cooling load savings are obtained through cooling systems, followed by wall characteristics, then glass characteristics, with the least for BO & D, with maximum reductions of up to 61%, 59%, 55%, and 21%, respectively. As for the peak cooling load reductions, wall characteristics, cooling systems, and glass characteristics had almost the same average values of 18.7%, 15.2%, and 17.2%, respectively, while BO & D are not reported due to the incomparable number of case studies. The parameters that have the most influence on reductions in peak cooling loads are wall and glass characteristics. In general, savings that are associated with wall characteristics are more significant for low-rise buildings than for high-rise buildings, while the latter is more influenced by glass characteristics. This is a reasonable conclusion since high-rise buildings, in general, acquire higher window-to-wall ratios than the former. In general, most studies considered glass characteristics, while fewer studies considered BO & D. This review has shown various aspects that are vital in studying building cooling load demand and its related energy performance.

Cooling processes play a crucial role in addressing diverse societal needs, particularly in providing thermal comfort and mitigating overheating risks, especially in hot and humid climates like Malaysia. This paper explores the significant contribution of space cooling to peak electricity demand and reviews existing research methodologies for assessing and predicting energy cooling requirements. Various approaches have been employed, often tailored to specific applications and needs. Notably, Geographic Information System (GIS)-based procedures have emerged as effective tools for estimating energy demand profiles by integrating energy performance data with georeferenced building stock. Through a synthesis of current knowledge, this review underscores the importance of understanding the energy cooling demand in Malaysian buildings and emphasises the necessity of incorporating geospatial elements in assessing cooling needs. By identifying research gaps, this article contributes to advancing our understanding of cooling demand dynamics and informs future research directions in this crucial domain.
