This workshop held in Brussels is the third of a series of four workshops co-organised by AIVC and ASIEPI (see ASIEPI WORKSHOPS for more information).  It has included a series of well structured country presentations, the view of various European associations, synthesis presentations and a panel discussion. More specifically, the workshop has focused on the following issues :

Article 4 of the EPBD stipulates explicitly that attention should be paid to indoor climate conditions: “Member States shall take the necessary measures to ensure that minimum energy performance requirements for buildings are setThese requirements shall take account of general indoor climate conditions, in order to avoid possible negative effects…”. This is also listed in the annex of the EPBD: The methodology of calculation of energy performances of buildings shall include… (d) ventilation;…

Mechanical ventilation and air conditioning control the indoor conditions with a specific high consistency range that is independent of external conditions, whereas passive systems cannot be regulated that precisely and quickly. However, passive cooling makes proper use of the existing natural possibilities and principles, uncharged by side effects, thus simulating better the natural conditions, providing a feeling of comfort and using less to no energy.

Based on the idea that the human body continually adapts to a variety of conditions, an adaptive standard, would not include fixed indoor parameters but, would aim to promote (easy) adaptation by using the following principles:

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

In line with the principle of equivalence, each Member State implements various EN standards into its regulations to assist in the evaluation of the performance of alternative cooling techniques. Examples of such standards are: ·         EN 13790: Energy performance of buildings-Calculation of energy use for space heating and cooling ·         EN 15241: Calculation methods for energy losses due to ventilation and infiltration in commercial buildings
