Impact of office buildings environmental systems control strategy on indoor environment quality and energy use in different climatic regions

Abstract

This paper presents the impact of temperature setpoint and thermal control material on energy use and indoor environmental quality in two different climates using the case study of an office room. The study is conducted in two stages. The first stage focussed on energy consumption for cooling, heating and ventilation of the office whilst maintaining thermal comfort determined from the Predicated Percentage Dissatisfied (PPD) and Predicted Mean Vote (PMV). The second part evaluates the influence of thermal control materials - Vacuum Insulated Panels (VIP) and Phase Change Materials (PCM gypsum plasters) on thermal comfort and energy saving. Comparison of indoor environment condition is performed using a computer simulation tool (ESP-r) and assessed according to the standards requirements in the selected regions. Computer simulation was verified by in situ measurements.
