21 February 2019. the municipality of Lamspringe in Lower Saxony is the 100th drawing municipality.
A research project conducted by natureplus in conjunction with IFEU compares insulation materials with regard to their environmental impact throughout their entire life cycle, including recovery and recycling.
Which insulation material is the best? This question is extremely popular in the construction industry and can ultimately only be answered in the context of the respective construction. In particular, there has so far been a lack of a holistic overview that enables builders and planners to identify the strengths and weaknesses of the various insulation material alternatives in terms of their life cycle assessment, without having to disregard subsequent disposal. Such a study was presented by ifeu (Institute for Energy and Environmental Research Heidelberg) and natureplus e.V. at the end of 2019. Their research project "Holistic Evaluation of Different Insulation Alternatives" was funded by the Deutsche Bundesstiftung Umwelt (dbu) and the Baden-Württemberg Ministry of the Environment. It is to be presented for the first time on 21 February as part of the Vienna BauZ! congress.
From the cradle to the grave
With this study, a comprehensive ecological evaluation of insulation material alternatives was carried out, especially with regard to possible future disposal paths of the insulation materials (from the "cradle to the grave"). The most common types of insulation materials based on mineral, renewable and synthetic raw materials were evaluated, and their application in different building components to meet specified requirements for thermal and cold protection was compared. The life cycle assessment data of the insulation materials for the manufacturing phase were taken from the natureplus partner IBO Vienna after researching various databases. Subsequently, the waste life cycle assessments were prepared by ifeu, in which, in addition to the processing loads, the respective benefits from the secondary products or energy recovery were quantified and included in the balance. For each insulation material, the most favourable disposal option from an ecological point of view was determined. These disposal options were included in the product life cycle assessments and the final disposal of the insulation material was also taken into account.
Material recycling hardly takes place
The waste life cycle assessments of all insulation materials show in most cases the specific advantages of material recycling and thus the sense of returning the waste masses to the economic cycle. The processed waste masses from the insulating materials can be further processed into (other) products or also returned to the original production as raw material. In particular, the recycling of synthetic and some mineral insulating materials significantly reduces the ecological rucksack that these products bring with them from the production phase. Material recycling also makes sense in the case of products made from renewable raw materials, although their use as substitute fuel in cement works is currently still more advantageous from the point of view of climate protection as long as hard coal is burned there instead. In practice, however, the recycling of insulation materials is only practised in isolated cases or for research purposes. The report therefore concludes that research and development of possible material recycling should be promoted in industry and in the field of waste disposal.
In the result Advantages for insulating materials from renewable raw materials
If material recycling takes place at the end of the product's life - contrary to current practice - blow-in insulation materials and flexible mats based on hemp or jute perform best, provided that all insulation types can be used, followed by polystyrene EPS boards and wood fibre mats. Where, as for example on the exterior wall, only board-type insulation materials can be used, EPS performs best, provided that the EPS is recycled in such a way that EPS beads are saved in a subsequent application.
If end-of-life disposal is as in the status quo and the energy benefit is included in waste incineration, the above-mentioned products made from renewable raw materials remain in the lead, but polystyrene deteriorates and dry-process wood-fibre insulation boards improve, even moving into first place on the exterior wall. Without taking into account the energy benefit, wood fibre boards and EPS insulation materials lose their advantages compared to other board and mat insulation materials.

Bonn/Düsseldorf. The fast, affordable and complete energy transition towards 100 percent renewable energy needs thought leaders and pioneers who inspire others. With the annual awarding of the German Solar Prize, EUROSOLAR puts these actors in the public eye and offers new impulses for a decentralised, citizen-oriented and regenerative conversion of the energy system.
EUROSOLAR e.V. and the EnergyAgency.NRW will jointly present the winners of the German Solar Prize 2017 on Saturday, 14 October 2017, at VillaMedia in Wuppertal.
In the run-up to the award ceremony, EUROSOLAR, in cooperation with the Hermann Scheer Foundation is organising a symposium to tie in with Hermann Scheer's visionary work "Der Energethische Imperativ" (The Energy Ethical Imperative). Together with the audience, the speakers will discuss how the rapid path to a renewable energy age can be implemented.
The award ceremony of the German Solar Prize begins with greetings from Lothar Schneider, Managing Director of EnergyAgency.NRW, Bettina Brücher, Mayor of the City of Wuppertal and Jörg HeynkesManaging Director of VillaMedia GmbH. Give an introduction Prof. Dr Andreas Pinkwart, Minister for Economic Affairs, Innovation, Digitalisation and Energy of the State of North Rhine-Westphalia and Stephan GrügerMdL and Vice-President of EUROSOLAR e.V. Afterwards, the award winners will be honoured. Dr Axel BergChairman of EUROSOLAR Germany, the highlight of the event.
This will be followed by a get-together with snacks.
Participation in the event is free of chargeRegistration is requested by 6 October.

Research has identified neighbourhoods as an important level of action for climate protection. For this reason, the BMBF, BMU and Federal Ministries of Construction and Transport have funded several research projects on sustainable neighbourhoods, which are now being processed. The consensus of the research projects presented and the funding bodies is that "it is important to economically research neighbourhood concepts for a climate-friendly heat and power supply as well as an environmentally friendly mobility offer" and "to sensibly link the individual elements in the sense of a functioning sector coupling.
The focus articles of the issue "Ökologisches Wirtschaften 3/2019" show on the one hand the potentials of the neighbourhood approach for the implementation of climate protection measures, but also present best practice examples and discuss the feasibility in practice.
The selection criterion for the projects presented was, as is to be expected with the newsletter of the IOER - Institute for Ecological Economy, that members are involved in them. Overall, the contributions provide a good overview of the neighbourhood research projects currently underway in Germany.

The aim is to redesign a 100% CO2-neutral neighbourhood.
To this end, a first building complex with approx. 25 buildings (113 residential units) and approx. 10 commercial units is to be converted in a climate-neutral manner between 2016 and 2018 and a first representative microgrid is to be developed in the quarter. In addition to office units, there will also be restaurants, workshops and a municipal gymnasium. So to speak "normal life", as one finds in most building complexes of this kind. In addition to the approx. 250 residents, approx. 80 employees as well as employers and house owners must be involved in the transformation process.
In addition to the energy supply, we want to develop new sustainable mobility options for people. The aim is to achieve more flexible, cost-effective and environmentally friendly mobility through the increased use of shared infrastructure in conjunction with sharing systems and the additional use of electric vehicles as temporary energy storage units.
The aim is to make this pilot ready for swarming after realisation in 2018 and a further year of test operation and to transfer it to the entire district in the years 2020 to 2030, thus creating the blueprint for a transformation in Wuppertal.
