To live up to its climate change pledge under the Paris Agreement, the European Union must ensure that all 250 million existing buildings, as well as all new buildings in the EU, produce near-zero greenhouse gas emissions. In a new report, European national academies of science, through their association EASAC, call for far-reaching policy action. "Policies have long focused on creating energy-efficient buildings that require less heating and air conditioning or generate renewable energy on site. However, the energy used to operate buildings is only part of the story. We need to broaden the scope and look at emissions from building materials and methods - both for new buildings and for building refurbishment," says William Gillett, Director of EASAC's Energy Programme.
Exploit potential at neighbourhood level!
The KfW programme "Energy-efficient urban refurbishment" promotes integrated energy-efficient neighbourhood concepts and refurbishment management with programme part 432. Programme parts 201 and 202 provide investment support for cross-building and infrastructural supply systems. The Federal Ministry of the Interior, for Building and the Home Affairs provides the funding for the energy refurbishment process from the individual building to the neighbourhood from the Energy and Climate Fund (EKF).
Annual DIW Heat Monitor based on data from energy service provider ista Deutschland GmbH: Heating energy demand in residential buildings declines again for the first time since 2015 - Rising prices, however, cause heating expenditure to increase by 2.4 percent - CO2emissions have fallen by 21 percent overall since 2010, but by only 2.6 percent when adjusted for temperature - Energy-efficient renovation in residential buildings almost stagnant
Climate protection has long been one of the most urgent topics for the housing industry. In order to achieve a climate-neutral building stock by 2050, the 24 founding companies of the Wohnen.2050 initiative met in Berlin on 28 January 2020 to found the association. The nationwide association was initiated by the Nassauische Heimstätte | Wohnstadt group of companies.
"Don't just talk about climate change, act" - under this motto, the Nassauische Heimstätte | Wohnstadt Group invited founding partners from all over Germany to found the Initiative Wohnen.2050 (IW2050) association. The overarching objective is a climate policy alliance, which, in addition to strategic cooperation and a technical and content-related comparison, primarily focuses on economic and financial concerns to achieve the targets.
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.

Senate adopts concrete measures for the next ten years and sets new CO2-targets for 2030 and 2050
December 3, 2019. Today, the Senate has set two decisive courses to achieve Hamburg's climate goals with an update of its climate plan and a new climate protection law. CO2 emissions are to fall by 55 percent by 2030, and Hamburg is to become climate-neutral by 2050. The climate plan describes the responsibility and the respective CO2 reduction targets in the sectors "transport", "private households", "trade, services, commerce" and "industry". It contains a large number of concrete measures which are to lead to the necessary reduction of CO2 emissions by 2030. The draft of the new climate protection law creates a binding legal framework for this.

The BUND Yearbook Ecological Building & Renovation, published by BUND Deutschland (BUND), helps by making owners fit for discussions with the house bank, architect, energy consultant and craftsmen. The guidebook, which will be available from November, shows what can be done and how: Based on numerous house portraits, the annual compendium helps the reader to find out which measures, building materials and technologies are best suited to their own project.
24 October 2019 Strengthen energy refurbishment of buildings and demand responsibility from landlords.

Incentive for less "grey energy" in the construction of non-residential buildings The City of Hamburg promotes the use of wood in the construction of new non-residential buildings with a floor area of 100 m² or more. The use of wood in the construction of new buildings is subsidised with € 800 per tonne of wood product.
Since the first edition of the FNR brochure "Straw Insulated Buildings" in 2013, building with this environmentally friendly and cost-effective material has developed positively.
In its August issue, ÖKO-TEST magazine evaluated 15 different roof insulation materials, including 5 with the natureplus seal of approval. The products are mainly suitable for insulation between rafters. The good performance of conventional products made of glass and rock wool, which all achieved "good", was striking. Of the natureplus-certified products, 2 insulation materials made of wood fibres - "Gutex Thermoflex" [...]
Some cities subsidize the use of certified insulation materials with a bonus to support resource conservation, carbon storage and particularly environmentally friendly products.
