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
Last year - for the first time since 2015 - tenants in Germany used slightly less heating (minus 3.2 per cent). However, at an annual average of 130 kWh per square metre of heated living space, the heating energy requirement in apartment buildings is now only back at the 2010 level. CO2-emissions have not fallen nearly as much as they would have to in order to achieve the 2030 climate targets: adjusted for temperature, they have only fallen by 2.6 per cent since 2010. These are the key findings of this year's heating monitor calculated by the German Institute for Economic Research (DIW Berlin) on the basis of data from energy service provider ista Deutschland GmbH. They are based on the heating bills of 300,000 multi-party houses in Germany and are adjusted for climate and weather conditions.
"If we only look at the absolute reduction in CO2 emissions, appearances are deceptive" Jan Stede
As energy prices for heating oil and natural gas rose by an average of 5.6 per cent last year, tenants spent 2.4 per cent more on space heating while demand fell. The regional differences in heating energy requirements and prices are very large. In western German households, seven per cent more is heated per square metre than in eastern German households. In 2019, heating energy requirements were highest in the Schleswig-Holstein Southwest and East Frisia regions, and lowest in central Mecklenburg/Rostock and Allgäu. Heating energy cost the most in Saarland and the least in Hamburg.
According to the study, there has been a significant overall reduction in CO2-emissions in the residential building sector have fallen by 20.7 per cent since 2010. However, this is largely due to the warmer winters. Adjusted for temperature and weather conditions, CO2-emissions have only fallen by 2.6 per cent over the past ten years.
"If we look at the absolute reduction in CO2-emissions, appearances are deceptive. The reduction of around 21 per cent, which would already make the climate targets unattainable, is hardly due to efforts to increase building efficiency. There is therefore no reason to scale back efforts to reduce emissions," says DIW economist Jan Stede, summarising the results.
"A sober assessment of ten years of building refurbishment shows that energy-efficient refurbishment does not automatically lead to less CO2. Climate policy measures must provide the right incentives for everyone involved: for landlords to invest and for tenant households to consume sparingly," comments Thomas Zinnöcker, CEO of energy and property service provider ista, on the results of the study. "More focus on results, unbureaucratic implementation and accompanying measures for consumers will make climate protection in buildings more effective."
Investment in the energy-efficient refurbishment of existing residential buildings is still too low to achieve the climate targets in the building sector. The plan was to increase the refurbishment rate to two per cent per year. Most recently, however, it was only one per cent. While energy-efficient refurbishment still accounted for a third of all measures in the building stock in 2010, in 2019 it was only a quarter.
The authors of the DIW study are therefore calling for stronger incentives for energy-efficient building renovations. "The higher subsidy rate for energy-efficient refurbishment and the planned CO2-pricing from next year could create additional incentives to invest more in this area again," hopes study author Franziska Schütze. With the CO2-However, care should be taken to ensure that social effects are cushioned. Tenants, especially those on low incomes, are disproportionately burdened by higher energy prices and have little influence on the building's energy efficiency and energy source. "Reimbursement of the income from the CO2-pricing in the form of a climate premium would relieve the burden on low and middle incomes and at the same time minimise the incentive effect of higher CO2-prices," suggests Jan Stede.

Frankfurt/Main (dpa) - The Frankfurt "Rent Decision Alliance submitted around 25,000 signatures to the electoral office on Tuesday. The participants want to achieve a referendum on the preservation and expansion of subsidized housing, as spokespersons for the alliance said before the handover.
The administration must now check whether the necessary quorum - the required number of signatures - has been reached and whether a citizens' petition is admissible. According to its own information, 42 organisations belong to the alliance, including the district association of the Left Party, the Asta of the Goethe University, Attac and several housing and urban policy initiatives.
They have three demands: The city-owned housing company ABG should only create subsidized housing; all tenants entitled to social housing should pay a maximum of 6.50 euros per square meter; prices per square meter of a maximum of 6.50 euros should apply in two-thirds of all ABG apartments that become vacant.

The district of Paderborn has achieved a climate target that can currently only be dreamed of nationwide. It has a green electricity supply of more than 100 per cent. This year, with the help of wind, sun, biomass and water, for the first time as much renewable electricity is being generated as is being consumed. Since the end of June, it has been exactly 112 per cent.
This is what the State Association for Renewable Energies in OWL determined. The association used figures from the State Agency for Nature, Environment and Consumer Protection (LANUV) as well as current data from the district of Paderborn. According to these figures, the more than 500 wind turbines, 11,500 photovoltaic systems and 53 biomass power plants generate slightly more electricity on an annual average than private individuals, trade and industry in the district of Paderborn require over the year: Almost 2.3 billion kilowatt hours.
This puts the Paderborn district in the Champions League nationwide: "There are very few regions that already fulfil the 100 per cent green electricity quota - in NRW, we are the first and so far the only one," says Kerstin Haarmann (Paderborn), Managing Director of LEE OWL. This is particularly remarkable because the district of Paderborn has a national average electricity consumption due to its share of industry. Smaller districts with little industry and commerce would naturally find it easier to reach 100 per cent. In a comparison of East Westphalia, the district of Paderborn is the lone leader: the district of Höxter is in second place with 63 per cent green electricity, followed by the district of Lippe with 23.5 per cent, Gütersloh with 20.8 per cent, Minden-Lübbecke with 17 per cent and Herford with 6.5 per cent. Bringing up the rear is the city of Bielefeld with a 4.5 per cent share of green electricity in electricity consumption.
The district of Paderborn has even achieved its climate target, which was unanimously approved by the district council in 2011, ahead of schedule. The plan was for electricity consumption to be completely renewable by 2020. "However, we don't have time to rest on our laurels in the fight against climate change," explains Jürgen Wrona (Delbrück) from the LEE OWL board. Measured in terms of total energy demand (electricity, heat and transport), the proportion of renewables in the Paderborn district is currently only around 27 per cent. "There is room for improvement, especially in the areas of heating and transport," says Wrona.

With the funding announcement "Solar building / energy-efficient city"Together with the BMWi, the BMBF is providing up to 100 million euros over the next five years for research, development and Innovation in the field of sustainable urban development.
In the first round of calls for proposals, more than 60 consortia from city administrations, research institutes and companies applied for funding. Of these, the following six were selected:
The projects are intended to show how energy consumption in urban quarters can be reduced, the intelligent network of electricity, heat and mobility and that renewable energies can be sensibly integrated into the energy supply.
