A GREEN DEAL, A HALLMARK TO MAKE EUROPE WORLD’S FIRST CLIMATE NEUTRAL CONTINENT
One of the first challenges of the new incoming EU Commission is to prepare the next steps for Europe to become climate neutral by 2050. President Ursula von der Leyen announced a Green Deal package by March 2020 with the first European Climate Law to make climate neutrality to become irreversible. The challenges ahead for Europe take part of a broader world wide discussion being undertaken at the UN Climate Change Conference COP 25 (2-13 December 2019). New figures from the latest Emissions Gap Report of the UN Environment Programme noted that greenhouse gas emissions have risen 1.5 % a year over the last decade. Worldwide, the last five years have been the hottest ever recorded. At current trends, we are staring at global heating of between 3.4 and 3.9 degrees Celsius by the end of the century.
Heating and cooling take half of the energy consumption in Europe, 80% of which is being used in buildings. In 2018 the revised Renewable Directive included for member states a new indicative target of 1,3% per year more renewables to solve the heating and cooling energy consumption. However, in buildings energy efficiency measures are the first to be used, with essentially to get the building envelope right.
MESSAGE TO REGULATORS
A housing renovation plan will no doubt be the ‘flagship’ of the European Green Deal. It is essential to include the already adopted EU guidelines for member states implementing the revised EPBD, in particular, “measures to adapt buildings to climate change, such as shading devices that prevent buildings from overheating during heat waves, which are systems that have a direct impact on the energy consumption of buildings by limiting the need for active cooling.”
CLIMATE CHANGE STARTS TO MOVE POLICY MAKERS TO A JUST TRANSITION FOR CITIZENS
The city of Vienna in Austria gives citizens financial stimuli to include shading in their building renovation
“The increase in the number of hot days in recent years calls for climate-friendly measures that give concrete support to the citizens of Vienna,” said Mayor Michael Ludwig.” Exterior shading such as blinds, shutters and awnings are therefore really efficient to reduce at low cost the overheating in dwellings”. The financial incentive from the city is 50% of the investment with a maximum of 1500 euro per building unit (appartment). The subsidy runs from December until 2025 and will be used for shading applied on 20 year old dwellings.
Italy continues to support citizens using energy savings measures
Italy has for some years now a tax deduction for mobile solar shading in dwellings. The tax deduction in 2019 is 50% of the cost of mobile solar shading and can be recovered by the consumer over a period of 10 years. The success of the measure speaks for itself: in 2018 tax deductions were requested for 160 million euros. For 2020 it may be expected that this fiscal incentive will be prolonged as a succesfull means to reduce the energy consumption for active cooling in dwellings.
Czech Republic puts forward shading to avoid overheating in dwellings
In Eastern-Europe Czechia is a forerunner when it comes to the recognition of shading as a passive measure for overheating in dwellings. Since end of 2018 the government provides financial incentives, in particular 20 €/m2 for manual shading and 40 €/m2 for automated shading.
