Environmental Heat Stress on Indoor Environments in Shallow, Deep and Covered Atrium Plan Form Office Buildings in Tropics

Abstract: Environmental heat stress on buildings through façades contributes to indoor overheating and thus increases demand for energy consumption. The study analyzed the problem, heat gain risk, of modern air-conditioned multi-level office buildings in tropics, for example Colombo. Plan form, orientation, sectional form and envelope were identified and theorized to understand design interventions to reduce the risk of getting heat stress on indoor environments. On-site thermal performance investigations in multi zones… Show more

“…Long-lasting, comfort-oriented redesign measures are the core topic of four papers in this collection. In [16], the indoor heat stress in modern, air-conditioned, multi-level office buildings is investigated in the tropics (Colombo, Sri Lanka). Design interventions on plan layout, orientation, sectional layout, and envelope characteristics are assessed in terms of heat-gain risk and associated energy consumption in 12 case studies.…”

“…Focusing on the energy performance the main parameters are the thermal transmittance (U) [32], a measure of insulation level of building component; the time lag, the decrement factor, the thermal heat capacity and the periodic thermal transmittance (Y IE ) as defined by [33] that describe the dynamic behavior of the building envelope during the summer. The effects on the indoor environment (in terms of heat stress) due to the climate overheating have been recently investigated by Rajapaksha [34] with reference to office buildings located at the tropics.…”

“…Based on the intended purpose of the APR, it should be able to move and reach the needed heights. A height reach of 3 to 3.5 meters may suffice for the interior painting of buildings (Chou & Ngo, 2016;Rajapaksha, 2020) and 9 to 10 meters for warehouses (Asadi et al, 2018). For exterior walls of highrise buildings, wall-climbing robots may be more effective.…”
