Dwindling raw materials, dwindling landfill space and ambitious climate protection targets make it essential to overcome the high use of resources in the construction industry. The film shows that there are already many ways to use building materials sustainably in the cycle: Recycled concrete, recycled gypsum, the reuse and recycling of bricks and the renewable raw material wood.
Around 60 percent of the resources used in Berlin are processed in the construction industry. This contrasts with millions of tonnes of building rubble and construction site waste. Every year, 2.2 million tons of primary raw materials are already saved in civil engineering and building construction in Berlin through the use of quality-assured secondary raw materials. But Berlin does not intend to stop there. By 2030, a further 1.4 million tonnes of primary materials are to be replaced by secondary raw materials each year.

Forest Minister Peter Hauk MdL: "With our call for ideas, we want to further promote municipal timber construction in the state and further consolidate our nationwide position as the No. 1 timber construction state".
A total of around 6.5 million euros in funding from the Baden-Württemberg timber construction campaign is available for the call for ideas for municipal timber construction concepts.
The online application deadline is February 12, 2020.
"In view of the global climate development, there is no way around the increased use of wood as a renewable and climate-friendly building and insulation material. Only buildings with a high proportion of wood can store larger amounts of carbon over centuries. With our call for ideas, we want to further promote municipal timber construction in the state and further consolidate our nationwide position as the No. 1 timber construction state," said the Minister for Rural Areas and Consumer Protection, Peter Hauk MdL, in Stuttgart on Friday (13 November). The aim is to establish Baden-Württemberg as a model of climate-conscious building culture. As far as possible, the state's building projects would be implemented in timber and timber hybrid construction. Now the state is also supporting the municipalities in their development towards climate-friendly construction with wood.
"The call for ideas focuses primarily on municipal concepts and approaches in urban development that lead to the implementation of timber construction projects. We are looking for new innovative approaches, for example in our own properties, neighbourhood development or the creation of entire settlements", explained Minister Hauk. This requires committed and innovative municipalities that lead the way as trendsetters. The ideas competition is intended to provide incentives for this. "Those who build with the renewable raw material wood protect the climate and strengthen regional economic cycles. The timber and mixed timber construction methods are ideal, for example, for adding on to existing buildings, closing gaps between buildings or renovating existing buildings", explained the Minister. Numerous projects are already proving that high-quality and sustainable further development of urban and rural areas with wood is economical and brings added value for the population.
The state is therefore promoting greater climate awareness in the construction industry with the Baden-Württemberg timber construction offensive. Wood is the only relevant building material that has a favourable CO2-balance and achieves an immediate storage effect. Thanks to innovative processing with low energy consumption, wood is used in a wide variety of forms and can contribute to a sustainable building culture with architectural accents.
Background Information:
Municipalities are invited to submit approaches to planning and building with wood in building construction. These can be initial ideas that must be assigned to one of the following four categories:
1. development and conception of the construction and renovation of own properties,
2. instruments and approaches of urban planning / development,
3. information, advice and education of those willing to build by the municipalities (communication)
4. other/special route.
The submission of ideas for the planning of individual objects, as well as neighbourhood and settlement approaches, consulting and qualification offers (internal and external), communication strategies and public relations, but also other formats in the municipal planning context are conceivable.
The call is designed to be low-threshold in order to address many municipalities. In a two-stage application process, a rough concept is first submitted online in the form of a short idea sketch. After an evaluation by a group of experts, selected municipalities have the chance to deepen the project idea and prepare it for implementation. Financial support of up to 20,000 euros each is available for this (1st stage). After a positive evaluation, there is the possibility of receiving further funding of up to 400,000 euros in the second stage for the implementation of their project idea (2nd stage).
The deadline for submitting a short outline of ideas via the online application is 12 February 2021 (1st stage). Interested municipalities can find more information on the website of the Timber Construction Offensive at www.holzbauoffensivebw.de
Since 1 January 2020, all new buildings and general renovations of the BIG Group have been subject to the Group-wide mandatory minimum sustainable standard.
Vienna (OTS) – The BIG minimum standard goes beyond the legal requirements and ensures that all projects of BIG and its subsidiary ARE achieve the klimaaktiv SILVER standard in any case.
The sustainable minimum standard of the Bundesimmobiliengesellschaft (BIG) is a catalogue of criteria that must already be taken into account in the planning process of buildings. This makes the implementation of 43 measures of the BIG Holistic Building Program (HBP)* and the achievement of at least 750 klimaaktiv points mandatory for all new construction and general refurbishment projects for which a plan invention procedure will be carried out from 2020.
By implementing the minimum standard, CO2 emission levels will be significantly reduced, climate-damaging building materials will be avoided and the phase-out of fossil fuels will be accelerated.
„The sustainable development of real estate is rapidly gaining in importance both nationally and internationally.As a federal real estate company, we see it as our responsibility to set special standards in this area. The implementation of the sustainable minimum standard is a significant milestone on the way to improved resource and energy efficiency", says BIG Managing Director Hans-Peter Weiss.
Other points covered by the minimum sustainable standard are an overall ecological assessment of the buildings (according to OI3) and a mandatory life cycle cost analysis. The inclusion of future follow-up costs allows a long-term economic consideration of the sustainability measures.
Austria-wide photovoltaics initiative
In order to achieve the phase-out of fossil fuels and to be almost emission-free by 2025, BIG is also launching the Austria-wide photovoltaic initiative this year. PV systems will be installed on around 20 hectares of BIG and ARE rooftops by 2023. In this way, the efficient use of solar power will significantly increase the share of renewable energy.
With the Holistic Building Program (HBP), BIG, together with e7 and Pulswerk GmbH, has developed the most comprehensive digital building configurator in Austria. It accompanies users through all phases of sustainable building projects - from planning to construction to operation - and thus becomes an individual online checklist for all relevant topics. In total, the HBP guides users through 7 thematic areas with a total of 73 criteria that cover essential aspects of holistic construction and thus serve as a clear project guide. The focus is on economic and resource-saving factors as well as ecological and socio-cultural factors. The real-time display of the project data entered in the online catalogue also contributes to the high user-friendliness of the HBP. Each entry of individual measures is immediately converted into points. The maximum total number of points that can be achieved per project is 1,000.

Photovoltaic modules can generate climate-friendly electricity for decades
Old modules must be disposed of properly
New BSW information paper provides information on dispensing points and important safety instructions
One advantage of photovoltaics is that they can supply electricity for decades if installed and components are selected correctly. If photovoltaic modules are no longer used to generate solar power due to damage or age, they must be disposed of properly in accordance with the German Electrical and Electronic Equipment Act (ElektroG). After all, they contain valuable raw materials.
"The recycling of solar modules is technically feasible today. Specialised waste management companies can recycle old modules in such a way that the raw materials they contain can be fed almost completely into a production process as secondary raw materials," says Carsten Körnig, Managing Director of the German Solar Industry Association (BSW). "It is therefore important that discarded modules are channelled into the materials cycle. Owners of photovoltaic systems, installers and operators of collection centres can find out where old modules can be handed in and what needs to be considered in our new information sheet."
For example, modules from private households can be disposed of free of charge at designated collection points such as recycling centres or the take-back centres of manufacturers and distributors. "As an electrical voltage is generated when light falls on the active cell layer in photovoltaic modules, it is important to handle dismantled modules for disposal with care," says Körnig. For example, module cables should be secured, modules should be carefully stacked and, if necessary, provided with edge protection. "The solar-active side of the module should always face downwards when stacking, and open contacts and damaged backsheets should be insulated before removal."
More than 1.7 million photovoltaic systems are in operation in Germany. Under normal conditions, a photovoltaic module can reliably supply climate-friendly electricity for at least 25 years, and usually much longer. The industry association therefore does not expect to see a large number of old modules for a good ten years.
