Climate-Resilient Office Buildings: Energy and Comfort in Japan's Future (2090s)
Original language description
This study evaluates the impact of climate change on energy consumption and indoor thermal comfort in a typical Japanese office building equipped with a Variable Refrigerant Flow (VRF) heat pump system, across five representative cities: Sapporo, Tokyo, Osaka, Fukuoka, and Naha. This study employs EnergyPlus to compare current (2020s) and future (2090s) Typical Meteorological Year (TMY) data, under Representative Concentration Pathway (RCP) 8.5 developed by the Intergovernmental Panel on Climate Change (IPCC) to estimate annual heating and cooling energy demands, Predicted Mean Vote (PMV), and Operative Temperature (OT). Findings reveal substantial reductions in heating demand, with decreases of 35% in Sapporo, 65% in Tokyo, 60% in Osaka, 79% in Fukuoka, and 100% in Naha, attributed to milder winters. Conversely, cooling demand surges by 26%, 19%, 20%, 30%, and 21% in these cities, respectively, driven by rising temperatures and humidity. Unconditioned zones, such as lobbies and corridors, experience severe overheating, with PMV values exceeding +3 and OT surpassing 34°C in the 2090s, particularly in humid subtropical regions like Naha and Fukuoka. These trends, exacerbated by increased Moushobi days and Urban Heat Island (UHI) effects, highlight the vulnerability of current building designs. The study proposes adaptive strategies, including climate-specific insulation, optimized Window-to-Wall Ratios (WWR), dynamic façades, and advanced Heating, Ventilation, and Air Conditioning (HVAC) controls, to mitigate cooling energy demand and ensure thermal comfort. By addressing region-specific challenges across Japan’s diverse climates, this research underscores the need for resilient, energy-efficient building solutions to adapt to future climate scenarios, promoting sustainability and occupant well-being.
