Supporting the roofing SMEs in the development and use of a new generation of roofing materials applicable with fault tolerant procedures, reducing the use of petroleum-based products

Final ReportSummary - NU-ROOF (Supporting the roofing SMEs in the development and use of a new generation of roofing materials applicable with fault tolerant procedures, reducing the use of petroleum-

The NU-ROOF project had the following main objectives:

1. obtain a novel waterproofing flat system based on multifunctional materials applicable with safe and fault-tolerant laying procedures, reducing life cycle impact of existing solutions;
2. set up a collaborative knowledge base including a customisation support system dedicated to the roofing associations and mainly focussed to the knowledge gained from objective No. 1.

The project, reaching its end, can claim a clear success in achieving on time all its objectives.

A) The first result is a new reflective, easy to produce and eco-sustainable waterproofing roofing composite: the long term ageing tests on the 'PES' version demonstrated a surprisingly strong attitude after the artificial ageing tests. No problems appeared too in a parallel natural ageing test exposed to two months natural ageing in Spain. This version is very close to the market requirements and constitutes the final result of NU-ROOF; some additional roughening to polyester will have to be done on the market version to increase mechanical anchoring. A PCT patent application is pending. An exploitation agreement has been discussed and negotiated several times (eight iterations) and signed by all legal representatives of the whole NU ROOF consortium. This document provides all rules for licensing, co-ownership of the Nu ROOF patent.
B) The project can claim the final release of the KM base: the web-based software, based on four modules is now fully operational (document management system, collaboration tools, customisation system, training and application guidelines. In particular, the knowledge base contains the application guidelines, recorded in movies and e-training sessions, in several tongues and subtitles.
C) A third technical and scientific claim of the NUROOF project was the knowledge generated in trying (successfully) to find alternatives to bitumen by using acrylic binders (Acryl or Enkryl). Also the use of bituminous emulsion (which can be processed at room temperature) was successful facilitating the possibility to introduce functional fillers like PCM and the manufacturing process at lower temperatures. Although this knowledge was not brought close to market scale up during the NU-ROOF project, the knowledge related to it can be used for further research on other applications outside the scope of the NUROOF project.
D) A fourth technical and scientific claim of the NU-ROOF project is the novel measurement protocol linked to the 'testing rig': a new comparative parallel assessment for thermal response of different building stratigraphies has been developed by NTUA and DAPP. The novelty of this assessment consist in plotting the rising and decreasing of the sun heat emission, from morning to evening, reproducing in a controlled way the heat gain on roofs.

Project context and objectives:

The main objective of NU-ROOF is to support the competitiveness of roofing SMEs (e.g. those involved in all aspects of production, transport, installation, maintenance and repair) along the entire value chain, including standardisation of roofing components and their application guidelines. Indeed, for those in the industry, there are well known problems which need to be addressed. These problems include that best practices are not captured and established in application guidelines, more efficient procedures and less wasteful materials are available, and the systematic process to bring new innovations / products to the market is fragmented, slow, and nearly ineffective. To overcome these obstacles, NU-ROOF project has identified the following main objectives:

1. obtain a novel waterproofing flat system based on multifunctional materials applicable with safe and fault-tolerant laying procedures, reducing life cycle impact of existing solutions;
2. set up a collaborative knowledge base including a customisation support system dedicated to the roofing associations and mainly focussed to the knowledge gained from objective No. 1.

After two years of project, the consortium was able to develop a new waterproofing composite based on a mix of partially recycled materials, with a reflective textile on top. The main innovation was related to the resistance of the top composite and the ease of production, which are two aspects totally new on the market.

The last year of the project was entirely dedicated to:

- complete the material testing and validation activity (a special importance will be given by the ageing tests that started at month 20 in TNO);
- supply the NUROOF membrane to the demo performers for installation in Barberino and Prague;
- complete the e-training system by implementing the recommendations of the roofers during the application tests;
- use the e-training system to train the demo performers;
- install the material on the roof (Dellacasa and Imprima will be deeply involved) showing how easy the product is in terms of application (and how good is the e-training platform);
- complete and validate the collaborative knowledge platform;
- make a clever dissemination activity, in line with the marketing needs of the involved industries and in line with the future research needs of the RTDs;
- decide for an IPR strategy, in particular the partners agreed to go for a PCT world-wide application;
- apply for a world-wide patent and manage the co-ownerships;
- reach a complete agreement on exploitation in order to avoid any possible conflict and start marketing the NUROOF technology as soon as possible;
- complete the life cycle analysis in order to 'certificate' that the environmental footprint of the product is lower than existing products;
- define a business model coherent with the industrial exploitation of NUROOF and the life cycle cost analysis;
- complete the NU ROOF project in time from a formal point of view (reporting and review meetings in particular).

Project results:

The S&T results are herewith organised per WP:

WP1: Functionality analysis and technical characterisation of roofing system materials

Based on deliverable D1.1 and D1.2 and several discussions between the participating project partners, general goals of the design of a new roofing system were formulated. Improving the energy performance of a roofing material means:

- reducing the cooling loads;
- reducing the urban heat island effect in summer;
- reducing the embodied energy, which is not the main goal of our project but rather a threshold that has not to be surpassed and that will be specifically measured by the life cycle analysis in WP6.

The NU ROOF system wil have to be therefore:

1) base membrane = impregnated non-woven which contains functional additives;
2) top membrane = functionalised non-woven which supports the reflective top coat; and
3) reflective top coat.

In the NU ROOF project, two concepts were developed:

- Concept 1 is a conservative approach with new parts such as a non-woven top membrane and a top coating applied onto the top membrane which reflects light.
- Concept 2 is a futuristic approach with very innovative solutions: besides the top coat and membrane the base membrane from conservative approach is also modified by incorporation of functional agents which have the ability to store heat.

Both concepts are designed to satisfy, as best they can, the target requirements defined from in WP1 (QFD procedure).

WP2: Construction of the knowledge base.

WP2 is devoted to the 'construction of the knowledge base', in other words WP2 was focused on fundamental research to develop and lab test the concept of NUROOF. The main conclusions drawn in WP2 are the following:

- The concept 1 prototypes can step into the industrial stage of development (month 24);
- There is not clear evidence that PCM provides a clear competitive advantage for energy saving, in line with the results of thermal modelling. Concept 2 is therefore stopped to allow deep focus on concept 1.

Although concept 2 will not be brought to full development during the NU-ROOF project, the knowledge related to it can be used for further research on other applications outside the scope of the NUROOF project. Probably the best future applications starting from the experience made in mixing PCM with bituminous emulsions and reinforcing fabrics is asphalt: TNO for example already developed a solar road which leads solar energy to a small solar panel within the road block. The first real scale experiment are being done with bicycle paths. Adding PCM's in the asphalt or underneath solar panels could be used to regulate the temperature of both of them for optimal energy efficiency.

Conclusions for top membrane support

A thin spunbonded nonwoven from polyamide calendered and thermally bonded (Variant NRVII) could be identified as being a good carrier for coating substrates. The most effective way for the backside to be sealed is the hotmelt technology where a hotmelt adhesive is applied to the nonwoven to close the structure. For the surface of the top membrane up to now the final coating consists of a first layer Encryl / Arginotec and a second layer of SurfaPaint from NANOPHOS (containing additionally SurfaPore Thermodry and Surfa C to improve the functionalities of the paint) which shows up to now (month 18) the best testing results concerning water permeability. The results for conductivity and reflectivity which are both decisive criteria for selection of best samples according to the requirements of climate regulation for roofing sheets can be optimised by adaption of the paint.

Conclusions for coating of the top membrane

Objectives of coating trials were on the one hand to seal the backside of the nonwoven to prevent penetration of paint to the surface and on the other hand to apply paint layers with several functionalities to the surface. Sealing of the backside was done by hot melt technology, EVA and PVB. PVB variants were completely succesfull wwith regard to delamination and staining resistance. Coating of the surface with slop padding (kiss roll) using different paints provides an even surface structure.

WP4: Construction of the collaborative knowledge platform

From the functionality point of view, the tool is working and presents module 1 (knowledge repository) and module 2 (collaborative functionalities). Module 3 (e-training) and module 4 (customisation support system) has been delivered at month 24 following the DoW plan. From the technical point of view, the system presents the following characteristics:

- programming language: Java E
- use of Redhad libraries
- database options: SQL, My SQL or Oracle.

WP5: Demonstration and validation

The role of the technical meetings and the frequent teleconferences for coordination of the testing activities and sending over of the samples was crucial, given the fact that the main testing facilities were geographically scattered:

STFI, Germany: testing of textiles, coating trials, application procedures, lamination trials, waterproofing trials;
Borner, Germany: mechanical testing, assembly trials, delamination trials, staining trials, emulsion trials, integration trials; flame resistance;
TNO, the Netherlands: microencapsulation, reflectance, artificial weathering;
NTUA and Nanophos, Greece: temperature, water resistance, viscosity, applicability, safety.

Conclusions from the fire retardancy tests (from D5.1): 'Both acryl based or enkryl based top fleece (with reinforcement) resisted enough to fire. Bitumen base compound resisted enough to fire even with 30 % recycled components. These base components could continue next tests.'

Conclusions from the reflectance measurements (from D5.1): 'The reflectance tests demonstrated that Arg-Surfa/Arg 3 % 2 layers reached a value of 75 %, which is acceptable in the market of cool roofing. This result is interesting since in the following test we will show that this formulation is easily applicable and highly waterproof'.

Conclusions from paint waterproofness test (from D5.1): 'Nanophos silicon based paint has outstanding results for waterproofness and can continue now tests for coating to "back-coated textile".'

Conclusions from the coating trials (from D5.1): "Variant 5 top fleece is the easiest to apply. Arginotec amount can be decreased to 3 % to reduce stiffness while backside can be improved by using PVB (polyvynilburethane) or Polyesther. The choice of PVB / PES was one of the most challenging tasks. Mechanical testing performed by Borner will finally validate the behavior of the top fleece after integration.'

Conclusions from the mechanical tests (from D5.1): These tests demonstrated that concept 1 variant 5 has a very interesting mechanical behaviour and allowed the consortium to finally validate each single components tested so far. The importance of these results complete the integration tests performed in task 3.2 (adhesion in production conditions). Final validation of the overall compound has been through weathering tests (T5.3) and application on the demo site (T5.2).

The objective of task 5.3 duly reported in D5.3 was to validate the final versions of the NUROOF membrane through all existing relevant standards, in order to gain confidence on market acceptance. Two NUROOF system versions have been tested according to European Roofing standards, one based on PVB oil barrier, one with polyester oil barrier. Borner, which is an historic waterproofing bituminous membrane producer has performed the basic static tests, which are a minimum requirement for market. UNYA, DAPP and BORNER have performed natural ageing tests (UNYA in Turkey, DAPP and Borner in Spain). TNO has performed long term artificial ageing. NTUA and Nanophos have performed all tests related to paint and thermal behaviour.

Regarding the basic tests: both versions (PVB, PES) showed equivalent results. Resistance to tearing and external fire exposure to roofs of the NUROOF felt are much better compared to traditional bitumen based roofing felts. The result of the fire resistance test is impressive, as only 50 % of the fire retardant was used, compared to traditional membranes. Resistance to abrasion is outstanding. Moreover, the NUROOF felt is about 20 % lightweight. Other mechanical test results are comparable to traditional roofing felts.

Regarding artificial ageing tests: they have been performed by TNO both on preliminary and final versions of the NUROOF roofing system. Variations in the system components (non woven with a backing and one or two layers of coating on top) showed that degradation of the hotmelt (backing) and adhesive may occur with the earlier version of NU-ROOF. A considerable amount (up to 20 %) of Arginotec had to be added to EVA in order to make it suitable for backing of the non woven and prevent staining of the surface. PVB prevented this staining provided that the proper type is chosen. The solar reflectance of the artificially aged NUROOF membrane is reduced by 2 %, mainly due to the reduction of VIS reflectance, while ageing does not seem to affect the NIR reflectance.

A disadvantage of the last PVB tested, was that it shrank considerably. A polyester non woven and backing showed instead very good resistance to staining and no or minimum shrinkage. Some loss of paint (spots) on the surface occurred, however, after 2200 cycles. Three options to improve the NuRoof membrane and avoid the above mentioned defects are proposed although the whole development team reached the conclusion that the polyester version, with some improvements on the top coat adhesion, can be fully acceptable to market.

Regarding natural ageing tests: PVB version withstands perfectly very hot conditions but tend, coherently to the artificial test, to show wrinkles after heavy rain. Although watertightness is still guaranteed, the aesthetics of the product is compromised and therefore the market acceptance would be very low. This version has to be improved. Polyester version, instead, passed the natural ageing test after five months of exposure. Results are better than artificial ageing test, where some superficial spots, not compromising watertightness, appeared. After having taken into consideration all the said tests, the NU-ROOF consortium approved the polyester version as final. It is important, finally, to remember that the polyester version is described and claimed in the PCT NU-ROOF patent application.

WP6: LCA, LCC and business model

Conclusions from the LCA: Comparing the different life phases, the NUROOF membrane is the best in terms of overall environmental performance:

- It has better reflective properties than grey slated membrane due to the use of a prefabricated top layer (although the contribution of a dedicated manufacturing process).
- It is 'greener' than black membrane painted with reflective top layer due to the need of this second product of recoating the bituminous layer every two years.
- It is 'greener' than both competitors in general because of the amount of recycled components (up to 47 % for the self adhesive configuration, up to 30 % for the welded configuration) that partner Borner achieved in the bitumen compound.
- The only indicator showing a slightly increased environmental impact is the 'terrestrial eco-toxicity potential', and this is due to the additional manufacturing steps connected in the preparation of the prefabricated top coat.

Conclusions from the LCC:

- The 'target costing approach' revealed that making no investment can be a deadly choice for a membrane producer: even making the optimistic hypothesis that the sales will decrease gradually until production reaches a capacity of 1/3 in 2030 (corresponding to 1 shift), the company would lose between EUR 1,3 million - EUR 6 million (net present value) in 25 years with respect to solutions 2 and 3.
- Buying a paint cabinet and an oven means making high investments. In our simulation, a 5 % mark up over the usual industrial costs would be enough to pay off the investment in five years. Moreover the industrial costs that we have calculated are EUr 1,8 to 4,8 lower than the target industrial costs that are given by the market selling price and the necessary mark up (5 %). This means that the selling price can be reduced or the mark up further increased. The downside for option 2 is that this solution requires a high investment for an SME and, moreover, this solution implies to radically transform the factory, which is sometimes not possible for physical reasons.
- The NUROOF solution pays off in 5 years with a 3 % mark up. This is due to the fact that the investment is lower than EUR 100 000, and very quick to implement. The problem is that the efforts are shifted to the variable costs and, in fact, the industrial costs that we have calculated are just EUR 1,0 to 2 lower than the target industrial costs that are given by the market selling price and the necessary mark up (5 %). This means that the NUROOF project will have to focus in reducing the operational costs of the prefabricated top coat to make it cost effective for the manufacturer.

Market analysis:

The target price, acceptable for the market, for NU ROOF will depend on the different countries. According to NU ROOF experts the price the roofer has to pay for the product is around EUR 12 although for some countries it will be higher and up to EUR 15.

The geographies that best fit the NU-ROOF applications are:

- hot countries with temperate winters (all standard waterproofing applications);
- all countries (for roofs containing photovoltaic plants or coloured roofs).

Potential sales for an SME producer like Borner after 10 years = 1,5 million m2 / year: it depends on the distribution and the countries. 1,5 million m² can be 15 000 roofs with 100 m² or 150 roofs with 10 000 m² therefore it should be realistic.

Overall potential market size in turkey, South Europe, Middle East, North Africa = 10 million m2 / year: if we estimate 200 million houses, 10 million m² per year is a realistic target for this technology.

Business models:

For Borner, the idea is to exploit the NU ROOF technology by implementing the system and targeting the new applications / geographies with the aim to increase sales and recover the scale up investment in few years.

The supply chain will be developed in this way:

- reinforce the sales agent network in the target markets;
- create new contacts to main contractors like construction companies working in the target markets;
- maintain focus on Mediterranean countries, Arabic countries, United States of America, tropical countries (especially Asian Tigers, where interest on cool roofing is growing).

The goal of a paint maker like Nanophos is to supply directly to producers of NU ROOF membranes or related top layer assemblers. The business model is purely B2B since producers of NU ROOF products may be Borner or licensees.

The goal of an additive maker like Nottenkamper is to supply directly to producers of NU ROOF membranes or related paint and textile producers. The business model is purely B2B.

The SMEs AG can potentially be interested in selling royalties of the NU ROOF patent to their associates. Additionally, although the knowledge base was designed uniquely to spread know how using the association network, a commercial exploitation of the knowledge base could be done through a fair and reasonable access fee linked to the patent license.

Contractors and commercial companies like UNYA, Dellacasa and Imprima are potentially interested in:

- selling royalties of the NU ROOF patent to producers belonging to their network of suppliers;
- reach exclusivity from the other partners for the sales of NU ROOF products.

The KM developers (Redhada and D'Appolonia) are contractually bonded to the owners of the KM platform (the SMEsAG). The possible business models behind them would be:

- selling software maintenance service to the NU ROOF SMEs AG;
- selling further software development to the NU ROOF SMEs AG, in particular for the development of the customisation support system;
- selling continuous updates of the document knowledge base, especially for the following themes:

i. patent state of the art;
ii. market reports in the cool roof domain;
iii. scientific papers related to sustainable solutions for bitumen industry;

- re-using the concept of KB to markets that are not correlated to the SMEs AG.

All these business models are reflected in the attached draft exploitation agreement.

The pillars of this document are the following:

- the draft was designed in the hypothesis that the patent would be filed under the patent cooperation treaty (PCT);
- the patent is co-owned on equal basis by all partners until the entry in the regional / national phases (month 30). A partner not willing to enter one regional / national phase will lose his share on that specific phase;
- each assignee is allowed to produce the NU-ROOF membrane without any permission or royalty to other assignees;
- each assignee belonging to a regional / national phase is free to sell royalties, but only after having reached unanimous consent from the other assignees on the regional / national phase. A 50 % success fee will be recognised to him;
- each co-owner is bound by contract to respect any relevant decision through a common decision procedure (voting); each co-owner has to be encouraged to promote license agreements in order to maximise the economical return of the patent; the requirement of previous unanimous consent, jointly with the revenues division adopted, is the best option for pursuing the goals above described;
- the RTDs shall not have proprietary rights on the foreground and specifically the patent. To balance this, the RTD will have the right to make use of the project foreground for the purposes of further research in any field - and to pursue economical benefits from this further research activity. This, however, cannot result detrimental to the business entities who have become co-owners of the patent. Any act of disposal by the RTD will be therefore subject to the business' entities' previous consent should it concern third parties operating on the same market.

WP7: Training and exploitation of the collaborative KM platform

Training and dissemination activities were one of the focal point of NU-ROOF project to reach the widest audience, and to enable the achievement of the maximum potential of penetration among the bitumen based waterproofing membranes contractors community. Task 7.1 activity was focused in achieving consensus over some important decisions:

- Lavrion management meeting (13 September 2011): a discussion was made on how to organise the first application trial, audience and relative pre training for the Mayen meeting;
- Mayen General Assembly (16 to 17 January 2012): after having performed the first application trial, the residual training plan was completed (result: the plan and the e-trainng requirements have been agreed and the Borner and IFD experts completed the first training experimental session;
- Training in Italy during the first demo application in hot conditions (result: train the Italian roofers related linked to LCT and Dellacasa);
- Training in Czech Republic during the second demo application in cold and wet conditions (result: train the Czech roofers linked to Borner Czech Branch, AMSP and Imprima).

The training sessions in Barberino and Prague made an extensive use of the e-training and application videos.

WP8: IPR management and dissemination

The exploitation strategy of the NU-ROOF consortium comprised:

- apply for a PCT patent;
- create an exploitation agreement.

Potential impact:

The NU-ROOF project has three main types of results and each one of them can be exploited in different ways. In particular, the NU-ROOF waterproofing technology (result: reflective prefabricated layer over partially recyclable bituminous support) has reached a stage that can be seen as promising for a potential industrial exploitation.

The Research for SMEs and SMEs AG scheme could be particularly complicated in terms of exploitation since, although the basic rule is simple (the RTD transfer 100 % of results to the SMEs and the SMEs AG), the differences in added value brought by the single partners to the project could foster discussions among partners if they are not clearly declared and discussed.

The activities of task 7.2 was therefore to define an exploitation strategy of the NU-ROOF consortium. After several meetings and conference call a decision was made to go for the following actions:

- apply for a PCT patent;
- create an exploitation agreement.

The amount of work required to perform these two activities has been very relevant but the output was considered unanimously valuable since the technology is now protected and there are clear rules to exploit it internationally and to keep together the whole consortium.

Regarding the patent application PCT/IT2012/000230, we provide herewith the title and the abstract:

'Bituminous based waterproofing composite with solar reflective properties, manufacturing method thereof and multiple prefabricated layer for such composite'

The present invention relates to a waterproofing bituminous composite with reflective properties of the solar rays; in greater detail, the present invention comprises a multiple prefabricated top layer with reflective properties of the solar rays and a bituminous support with waterproofing capability.

Furthermore, the present invention relates to a process for the production of waterproofing bituminous composite with reflective properties. Furthermore, the present invention relates to the laying of the waterproofing bituminous composite with reflective properties for covering roofs.

The development of the present invention is the result of the efforts made by a consortium of research entities, chemical industries, construction companies, bitumen membrane producers and retailers. This research has been co-funded in 2009 by the European Commission within the Seventh Framework Programme (FP7).

Regarding the exploitation agreement:

This document provides all rules for licensing, co-ownership of the NU-ROOF patent. The pillars of the exploitation agreement document are the following:

- the draft was designed in the hypothesis that the patent would be filed under the PCT;
- the patent is co-owned on equal basis by all partners until the entry in the regional / national phases (month 30). A partner not willing to enter one regional/national phase will lose his share on that specific phase;
- each assignee is allowed to produce the NU-ROOF membrane without any permission or royalty to other assignees;
- each assignee belonging to a regional / national phase is free to sell royalties, but only after having reached unanimous consent from the other assignees on the regional / national phase. A 50 % success fee will be recognised to him;
- each co-owner is bound by contract to respect any relevant decision through a common decision procedure (voting); each co-owner has to be encouraged to promote license agreements in order to maximise the economical return of the patent; the requirement of previous unanimous consent, jointly with the revenues division adopted, is the best option for pursuing the goals above described;
- the RTDs shall not have proprietary rights on the foreground and specifically the patent. To balance this, the RTD will have the right to make use of the project foreground for the purposes of further research in any field - and to pursue economical benefits from this further research activity. This, however, cannot result detrimental to the Business Entities who have become co-owners of the patent. Any act of disposal by the RTD will be therefore subject to the business' entities' previous consent should it concern third parties operating on the same market.

Regarding the potential impact (including the socio-economic impact and the wider societal implications of the project so far), the NU-ROOF project can claim the following concrete result: A young techician was hired in Borner to mainly advise architects, planners, investors and other deciders on the NU-ROOF product

The ramp up production is scheduled week 12-13 (2013), with the aim to install a demo model roof within Börner's plant.

The potential sales forecast described in D6.3 (business model) have been updated:

a) Potential sales for an SME producer like Borner after 10 years = 1,5 million m2 / year: it depends on the distribution and the countries. 1,5 million m² can be 15 000 roofs with 100 m² or 150 roofs with 10 000 m² therefore it should be realistic.

b) Overall potential market size in Turkey, South Europe, Middle East, North Africa = 10 million m2 / year: if we estimate 200 million houses, 10 million m² per year is a realistic target for this technology.

The geographies that best fit the NU-ROOF applications are:

- hot countries with temperate winters (all standard waterproofing applications);
- all countries (for roofs containing photovoltaic plants or coloured roofs).
