There are big decarbonisation gains to be had in a renovation wave in Central and Eastern Europe (CEE) precisely because their building stock is very energy-inefficient, explains Christophe Jost at CEE Bankwatch. But Bankwatch's report on eight national plans - Bulgaria, Czechia, Estonia, Hungary, Latvia, Poland, Romania and Slovakia – reveals weaknesses in scale, funding, strategy and policy. Many are planning to comply with only the former 40% … [Read more...]
Buildings Retrofits: inaccurate efficiency ratings are going to waste budget
Buildings renovations are going to be expensive, and complicated to roll out. Accurately predicting how much energy a building actually wastes will make that process easier and cheaper. EPC ratings are used to categorise the energy efficiency of homes. But Freya Wise at The Open University quotes research in Europe, along with her own investigations in the UK, to show that a lot of older buildings waste less energy than the standard estimates are … [Read more...]
Why expensive Buildings Renovations? By the time they’re done the grid will be emissions-free
The big budgets being talked about for the transition require us to decide how much to spend, and on what. Maximilian Auffhammer at the Energy Institute at Haas explains why he thinks a lot of the money being earmarked for buildings renovations would be better spent elsewhere. By the time the renovation wave has successfully “reached the shoreline” in the next few decades buildings will be powered overwhelmingly by clean grids (that’s the plan, … [Read more...]
How to ramp up Green Mortgages for climate-friendly house improvements
Green mortgages are used to finance climate-friendly house improvements. In the U.S. they already exist, but need to be made far more accessible and marketed widely. Greg Hopkins at RMI cites their report “Build Back Better Homes: How to Unlock America’s Single-Family Green Mortgage Market” to explain that the financial markets are looking increasingly favourably at lending that is certified as ESG (environmental, social, and governance). … [Read more...]
Buildings Renovation in Germany: success story or potential failure?
The German Federal Association of Housing and Real Estate Companies (GdW) has claimed that money and effort spent on the nation’s buildings renovations have not worked. But Andreas RĂĽdinger at IDDRI has looked into the evidence and concluded that the opposite is the case. CO2 emissions from the residential sector in 2018 were 37% lower than in 1990. Though final energy consumption was broadly stable, that’s because efficiency gains were offset by … [Read more...]
Europe’s Deep Buildings Renovations need to quadruple
The European Green Deal must grasp the opportunity to kick-start buildings renovations, says Thibaud VoĂŻta at the IFRI Center for Energy & Climate, summarising his report “The Renovation Wave: A Make or Break for the European Green Deal”. A lot of European buildings are old, and progress is slow. Stiffer regulations have helped, and household energy efficiency has risen by 30% since 2000. But the number of deep building renovations completed … [Read more...]
Why savings from the 2009 Buildings Refits stimuli were poor. Let’s do better this time
“Shovel ready” buildings renovations and refits can play an important part in a nation’s economic recovery programme. It gets money straight into the pockets of manual workers doing the refits, across the whole country, cuts the energy bills of all (both low and high income households), and accelerates efficiency gains for meeting climate targets. But first we need to learn lessons from the U.S. renovation stimuli of 2009, says Meredith Fowlie at … [Read more...]
No Energiewende without Wärmewende: making Germany’s Heating emissions climate neutral (…nearly)
In Germany, space and water heating in buildings accounts for almost a third of total final energy consumption. Because over 90% of its 22m buildings are fuelled by oil and gas, that makes the sector emissions very intensive. The government’s ambition is to have a "nearly climate neutral building stock" by 2050. But although those emissions have fallen by 44% since 1990, progress has largely stagnated since 2011. Freja Eriksen at Clean Energy … [Read more...]
