Visual thermal landscaping: a novel method in personalising thermal comfort

Do the occupants adapt to a predictable thermal environment, which is always the same? In this work, Visual Thermal Landscaping (VTL) model was applied, which is a novel method in analysing thermal comfort through a human centric approach in regard to individual differences and spatial context. This is a qualitative architectural analysis method, in which data is mapped on the building layout. It allows intuitive interpretation of collected data through field studies of thermal comfort according to the meaning, individual information (e.g. comfort survey), connections between individuals, their environment and other individuals within the context. Simulation and statistical analysis were also applied on the field data. The simulation accurately predicted the temperature and energy use in the building. The PMV and the statistical analysis suggested that a slight change in the temperature will improve thermal comfort conditions. However, the VTL model revealed the complexity of satisfying everyone with a predictable uniform and steady indoor temperature, due to individual differences and the dynamic aspect of thermal comfort. This study suggests the application of personalised thermal comfort systems to enhance user comfort and satisfaction.
