Final Report Summary - EURACTIVE ROOFER (EURopean performance requirements and guidance on ACTIVE ROOFs)
The main strategic aim of EUR-ACTIVE ROOFER project was to supply tools for the European roofing trade, which enables the European roofer:
l. to respond to the new demands for integration of roof accessories and fittings;
2. to upgrade from delivering just roof tiles to delivering total (active) roofs.
This will provide great added value to the building, significantly reduce failures and increases the overall quality of roofs, and in this way enhances the profit of the roofing trade. EUR-ACTIVE ROOFER aims at both newly built roofs and existing roofs, which are aimed to be upgraded towards active roofs.
Main final objectives of the project
The main final objectives of the project are:
1. to set up and complete as far as possible a database for existing and future roof systems;
2. to produce a photovoltaic and solar thermal best practice catalogue concerning technical and architectural integration techniques for active roofs;
3. to produce a best practice glide and legislation proposal for safety devices;
4. to produce a prestandard on active roofs and introduce it into the EU normalization circuit;
5. to execute full scale tests of active roofs and take up the experiences into the best practice documents; 6. to produce a guideline for design and application of active roofs; 7. to set up and produce a training programme for active roofers; 8. to disseminate the produced roof information via newsletters, congresses, workshops, presentation, articles etc.
Main results of the project
The input for these results are based upon the experiences and project activities of many laboratories and full scale tests which are carried out in various places in Europe.
EUR-ACTIVE ROOFER database
A database was developed in which both existing and future roof systems were included. This database focuses on the performance required by roofs, both now and in the future. The database was filled in based on information from the participating IAGs and the outcomes of the work programmes (WPs). The content of the database has a dynamic character, so it developed during the project, depending on the availability of the results of other WP's and also will be further developed after the end of the project.
The classification systems have the following main features:
1. Design aspects (orientation, building, physics, materials and forn)
2. Applications (renewable energy sources, energy storage, ventilation, smoke and heat evacuation)
3. User aspects (assembly, maintenance, safety).
4. Roof types (flat roofs, sloped roofs and bent roofs)
Best practice catalogue active roofs
A best practice catalogue of solar thermal and PV integration in roofs has been created based on inputs from all partners of the involved WPs, roofing organisations, manufactures and contractors concerning installation techniques. Also active component suppliers and consultants contributed with knowledge on system contributed to the catalogue. In this catalogue are taken up pre-fabricated elements, building elements and traditional element for application on flat roofs, sloped roofs as well as bent roof.
Best practice guide and legislation safety
ln the best practice guide and legislation safety examples were gathered from the partners from different countries, focusing on the most interesting and innovative solutions. It was classified into five main areas; safe access to the roof, working platforms, guardrails, hooks / anchors and personal fall arrest systems.
One should consider that in roof works collective safety systems are preferred, and sophisticated roofer works require working platforms instead of hanging rope. Some promising mobile systems are worth including.
Additionally an overview of the legislation is given and proposals are made, such as the recommendation for a double independent safety system in use and necessary surveillance of permanent safety devices.
Pre-standard on active roofs
ln the developed pre-standard on active roofs are summarised proposals for test methods and requirements for the most important aspects in order to define the quality of active roofs, especially focused on the building integration of solar energy systems. The content of this document is based on the results of the work packages. The final document is presented as a proposal for pre-standardisation to the relevant CEN TC committees as input for a final European standard in this working field and accepted as a work item within the TC 128 (in cooperation with TC 254).
This European pre-standardisation document specifies the application of solar energy systems (photovoltaic as well as thermal) as a stand-alone or integrated part of building components or units. It concerns building roofs as well as facades, residential buildings as well as commercial and industrial buildings. Where relevant, the provisions described in this proposal are to be applied to complete solar systems that are installed (in accordance with the guidelines of the supplier) in its intended architectural context with all construction details included.
Guideline for design and application of active roofs
This document provides a basic guidance for the design, application and performance of active roofs as well as for the development of products for such roofs. It was drawn up as a foundation for the work of engineers, architects, planners, manufacturers and roofers. It is the basis for further standards which deal with individual products, test methods and application.
A wide variety of new products such as PV systems and solar collectors, roof lights, ventilation devices, insulation and safety devices are being introduced into roofing. The roof is thereby transformed into an 'active roof'. The quality of these products as well as safety equipment for installation and maintenance is, when installed in a roof system, in many cases insufficient because there are currently no standards or legislation to assess their performance. At the same time, good products get poorly installed by inexperienced roofers. This guideline will help the roofing trade to improve their products and to reduce barriers to trade, restore consumer confidence in active roof products and improve competitiveness, allowing them to increase their markets. Also this document may lead to a mark for active roofs in the future.
