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...]
Buildings Efficiency: France must embed deep retrofits into its market
France’s energy efficiency ambitions for buildings are well off target. Buildings account for 28% of the nation’s emissions and they’ve hardly reduced since 1990 – only by 3%. It’s because of the lack of development of the buildings renovation sector, explains Andreas RĂĽdinger at IDDRI. Without it, there’s little chance of renovating 500,000 housing units per year and bringing the entire housing stock up to the "low-energy building" (BBC) … [Read more...]
