summer comfort

Adaptive comfort builds on the principle that people experience differently and adapt, up to a certain extent, to a variety of indoor conditions, depending on their clothing, their activity and general physical condition. Therefore, contrary to the conventional cooling which is based on pre-calculated temperatures and humidity levels, the adaptive approach is based on a non fixed set of conditions, taking into account thermal perception and behavior of the user, requiring him to take an active role in controlling his indoor environment.

The main international guidelines and standards on thermal comfort are: ·         International Standard ISO 7730. This standard is based on Fanger’s Predicted Mean Vote (PMV), which predicts the mean thermal sensation of a group of people, and the Predicted Percentage of people Dissatisfied with the environment (PPD). ·         ASHRAE 55 defines conditions that are being considered satisfactory for a specific percentage of users, including calculation methodologies for thermal comfort based on PMV/PPD

As has already been done for centuries before us, good indoor climate conditions during summer can be achieved through efficient use of the physical and natural conditions and sources around the building such as its position and orientation, the relief, the climate, the vegetation, the wind direction, air velocity etc. During design of the building such parameters need to be taken into account to prevent the building from overheating, by using proper materials, making efficient use of windows and openings, providing sufficient shading, night cooling, etc.

ASIEPI stands for 'Assessment and Improvement of the EPBD Impact (for new buildings and building renovation)'. The project addresses 6 technical issues:EPBD requires Member States to define building energy performance requirements... but did the Member States take this opportunity to strengthen their existing legislation? Member States are free to define their calculation methods and their requirements... Is it therefore possible to compare requirements across Europe? If yes, are the requirements from one country more severe than

The main objectives of ASIEPI WP7 are to create or increase awareness of the MS around available alternative techniques and technologies that improve thermal comfort without increasing the energy consumption and how to assess the energy performance of such techniques. The activities within this WP cover a collection and analysis of the situation of the EPBD implementation in those Member States who already have specifications regarding summer comfort and air-conditioning.
