Summary report
This summary report provides a synthesis of the work on the summer comfort and cooling issue. The conclusions and recommendations are presented in part A. These constitute the most important result of the project. Part B gives an overview of all other project material related to that topic, which allows you to easily identify the information most pertinent to your interest at any time. Part C lists the project partners and sponsors.

Alternative cooling calculation methods: Comparative simulations
Summer comfort assessment is a very complex issue and it is not evident that the existing calculation methods and tools developed in the context of the regulatory procedures have the adequate level of assumptions if passive cooling concepts and strategies are to be promoted.
This report addressed topics such as solar heat gains attenuation, night cooling dissipation, assessment of risk of overheating or zoning. It proves that some common assumptions of the calculation methods can become a barrier to the penetration of passive cooling in buildings.

Evaluation of the calculation methods for summer comfort and cooling
This report aims first of all in analysing the existing experience of MS with summer comfort and cooling calculation methods. Secondly the advantages and disadvantages of their calculation methods, as well as the pros and cons from their practical application and operation are indicated.
In order to serve the purposes of this report experiences were gathered from 7 EU countries (Belgium, France, Greece, Germany, Italy, the Netherlands and Poland) and from 2 non-EU countries (Israel and Japan) in December of 2008. The analysis of this information formed the basis of the report.

Handling of alternative cooling techniques
The aim of this report is to evaluate the extent to which alternative cooling techniques are covered by the procedures used by the MS and the way this is done. In the context of this report, alternative cooling techniques are considered to be the cooling techniques that improve summer comfort substantially, without (or in a very limited manner) increasing energy consumption and which in general do not rely on the vapour compression refrigeration cycle.
In order to assist in this report, information collected by means of a questionnaire from 9 Member States was used.

Additional requirements related to summer comfort and air conditioning
This report deals with the collection analysis and guidance regarding additional requirements related to summer comfort and air conditioning in line with Article 4 of the EPBD.
A questionnaire included in the annex has been distributed and answered by 10 participants or subcontractors of the ASIEPI project. The questionnaire includes general and specific information regarding present summer comfort and energy requirements in the national building regulations. The analysis of this information forms the basis of this report.

Summer comfort and cooling in the energy performance calculation methods
This survey makes an inventory of the way in which the overheating analysis and the energy consumption for cooling are handled in the EPB-calculation methods of 13 European countries. Focus is on the input variables of the calculation methods. These determine the design options that the methods reward, and thus the market stimuli that are given.
