International symposium on the interaction between human and building environment
The 8 papers in this special issue of Building and Environment are developed from papers initially presented at the International Symposium on the Interaction between Human and Building Environment, which was held at National Research Laboratory of Human & Building Environment in Yonsei University, Seoul (2008). People’s perceptions of comfort and satisfaction are influenced by cues from the built environment, yet humans adapt or attempt to control the indoor environment, to create a different set of conditions. This interactive field was the subject of the symposium. These papers cover a broad range of topics. Nicol et al. derive the equation for thermal comfort in free-running buildings for European Standard EN15251, using data collected by the EU project Smart Controls and Thermal Comfort (SCATs). Arens et al. find that the A class (category I) in these standards confers no relative satisfaction benefit to individuals or to realistic building occupancies. Kwok et al. argues that both mitigation of greenhouse gases and adaptation to climate change should be added to our building codes and standards. Zhang et al. designed task – ambient conditioning (TAC, also known as personal environmental control) systems that heat or cool only a few dominant body parts (feet and hands in cool environments, head and hands in warm environments). These systems can provide comfort in a wide range of ambient environments with a small amount of energy. Akimoto et al. tested a TAC system in a real building, which satisfied occupants at high ambient temperatures. Toftum finds that even though the development and application of new indoor environment sensors and HVAC control systems may allow for fully automated IEQ control, such systems should not compromise

occupants’ perception of having some degree of control of their indoor environment. Tham et al. found that a lower room air temperature increased whole-body cooling sensation and reduced thermal comfort. The cooling sensation activates the brain and excites the sympathetic nervous system controlling thermoregulation, elevating mental alertness or arousal. Kim et al. designed a natural ventilation opening using Hanji, a Korean traditional paper. This kind of trials could help to induce people behavior to control their micro-climates. The guest editors sincerely hope that you find useful information in the special issue. We would like to express our sincere appreciation to Professor Qingyan Chen, Chief Editor of Building and Environment for his help and advice of its publication. Also we would like to give a special thanks to Korean Ministry of Science and Technology which funded this valuable conference.
