For several years indoor comfort is measured in halls of hospitals by architecture students from the Delft University of Technology. Questionnaires and interviews have shows that patients and visitors have very few complaints about the indoor comfort in hospital halls.

Aeroseal technology utilizes air laden with fine aerosol particles (2-20 μm) to pressurize a duct system, resulting in deposition of those particles at the leaks within that duct system. By reducing leakages of duct systems by 90% in average Aeroseal sealing technology allows reducing leakages to a standard better as air tightness class D or ATC 1 for a complete system. Aeroseal technology can be applied in new constructions as well as in existing systems to improve energy efficiency, cleanliness of ventilation systems, IAQ and comfort.

Comfort and energy saving are two important concepts treated in current buildings in order to maintain a good air quality reducing the energy consumption. According to International Energy Agency (IEA) buildings represent 32% of total final energy consumption, and the need for reduction of CO2 emission leads to pay attention to the energy demand in buildings. On the other hand maintaining a good-quality environment helps to improve the productivity and effectiveness of workers.

For over a decade now, the OQAI — Observatoire de la qualité de l’air intérieur [French observatory for indoor air quality] — has been leading research into indoor air quality and occupant comfort in living spaces: housing, schools, offices, leisure spaces.

Night ventilation has been applied successfully to many passively-cooled or low-energy office buildings. This paper analyses the thermal comfort achievable in office buildings in Spain according to European standard EN 15251:2007. Furthermore, the comfort level is evaluated using the Degree Hours (DH) criteria and the maximum indoor temperature.

This paper presents an ideal and worst case scenario approach for occupancy modelling in early design stages which can be used in building simulation. It defines the range of impact that occupant behaviour can have on comfort and energy performance in buildings, and can thus contribute to the decision making of architectural projects in early design stages.

Thermal comfort, determined by the influence of the indoor environmental parameters on thermal sensation, is regarded as an important indicator of human wellbeing and health. Neurophysiological mechanisms are responsible for thermal sensation. Models of thermal sensation could be very useful in design of new high performance buildings. Humans do not sense temperature directly. Temperature information is coded into the firing rate of temperature sensitive neurons (thermoreceptors). Human skin contains two types of thermoreceptors “cold” or “warm” sensitive.

In the field of building design a rather conservative culture dominates: during the design process, standards are used to achieve physiological comfort. Physiological comfort is a necessity in order to achieve psychological comfort and eventually occupant satisfaction and overall wellbeing. To achieve occupant satisfaction and wellbeing, physiological comfort as well as psychological comfort have to be met.
