Thermal performance of double brick wall construction on the building envelope of high-rise hotel in Malaysia

Comparative analysis of conventional and modern high-rise hotels in Penang based on hourly simulation of cooling load performance using DesignBuilder

“…Conversely, the external cooling loads are loads that are formed due to heat gains in the conditioned space from external sources through the building envelope or building shell and the partition walls. The heat sources of external loads include the heat gain from the exterior walls, solar heat gain transmitted through the fenestrations, and conductive heat gain through the fenestrations [8].…”

“…Building energy use is intimately touted to the immediate ambient climate, and previous studies have anticipated that the cooling energy demands in the hot and humid climate will increase significantly with the future trend in climate change. The building cooling load prediction invariably acquires weather data and the conduction transient heat transfer analysis for specific facade construction [8]. Collectively, while building performance regulation, including the Overall Thermal Transfer Value (OTTV) has been made mandatory nationwide, most large hotels still need to undertake the OTTV performance evaluation [9].…”

“…Clearly, a majority of local hotels have not undertaken the façade OTTV performance calculation. In consequence, the performance of hotel façades concerning energy efficiency is faintly established [8]. Therefore, it has become the premise of the study to firstly evaluate the thermal performance of the façade design of modern and conventional hotels based on the hourly space cooling load and the annual cooling energy consumption intensity of these hotel guestrooms and present a comparative analysis between the selected case studies to draw gain insights on the thermal performance of hotel façade design in the locality of George Town, Penang.…”

Eraikin pasiboen karakterizazio termikoa: landare-fatxada modular baten kasu-azterketa

“…Azken urteotan, azterketak egin dira landare-azaleren aurrean sortzen den aire barearen geruzaren eta hostoek eragindako itzaltzearen ondorioei buruz. Hong Kong-en egindako ikerketa batean [14] transmisio termodinamikoaren eredu bat garatu eta baliozkotu zuten, beroaren transmisioa eta landare-gainazaletako tenperatura-aldaketak simulatzeko, eta eguzki-babesaren eta itzaltzearen efektuetan sakontzeko.…”
