Brief report giving an overall evaluation of the feature and describing the basic concept, the methods behind, existing good practices and how to implement it.

Report on the identification of suitable methods and approaches for the assessment of the feature.

This material consists of the Excel spreadsheets and user guide for the indoor air purity index. The proposed method considers outside air quality and indoor air purity in the building with a ventilation system equipped with an air filter. This method indicates that buildings located in the area with high outdoor air pollution require higher air filtration system efficiency to get the same air purity inside the building as in the cases of location with low outdoor air pollution.

This material consists of the Excel spreadsheets and user guide for the local air pollution contributor index. The proposed method considers fossil fuel used in the building for heat and electricity generation for the functions included in the national EPC system. In the local air pollution contributor index assessment method, the calculated building emissions will be compared with reference emission and for each pollutant, an index level will be assigned. Using the amount of building energy use and the type of the building energy source , the building emission indicators are calculated. Next, the reference emission indicators are calculated using reference delivered energy and reference energy sources. The reference values will be estimated based on national regulations. Using calculated values, the ratio of building to reference emission indicators will be calculated. The ratio of leading pollutant will be assessed using a scale of indexes. The indexes show what the building impact on outdoor air pollution in comparison with reference values is.

This report provides the summary of the outcomes of the testing activities for each of the 10 features in one or several implementing countries. This is mainly based on the analysis of the evaluation questionnaires filled out by the implementing partners, but also on the content of the testing results reports. The questionnaires hereby consist of general questions along the testing steps, questions on testing time and related costs, an evaluation against defined cross-cutting criteria (Quality and Reliability, User-friendliness, Economic feasibility, and Consistency with ISO/CEN standards) and final thoughts.

This report brings together the outputs of the evaluation of the test projects alongside the insight from end-users and stakeholders. It includes estimations of (1) the barriers and drivers for the wide uptake of the feature, (2) the effects of the wider implementation of the developed innovative feature of EPCs in Europe and (3) the necessary next steps in order to implement the innovative feature in the certification schemes around Europe.
