We just checked into our hotel in Palma and one of the first things I noticed is that as soon as you open any of the windows/doors, the AC automatically turns off. A message on the thermostat then alerts you that it will come back on once you close the windows. I haven't yet figured out how this particular hotel room is sensing that things are open, but it's relatively easy to do this at home through smart thermostats and sensors like these. I make a real concerted effort to do this manually, and so it's great to see it automated in a hotel room, where people are naturally going to care less about wastage. Europe is so far ahead of North America when it comes to energy efficiency.
One of the things that you'll notice on real estate listings in France is an Energy Performance Diagnostics (EPD) rating. In French, it gets reversed, and so it's a DPE (diagnostic de performance énergétique). What it tells you is how much energy the dwelling (or building) consumes and how much greenhouse gas it emits. And it is a requirement on all real estate listings and for all dwellings, except those that are occupied for less than 4 months per year. The output of this diagnostic is a rating from A (best) to G (worst).
According to FT, this is how primary residences in France rank today:
Less than 5% of homes are rated A and B (the most energy efficient). And many more are rated G and F. Beyond just being energy inefficient, this is potentially a problem because there are penalties and restrictions for the lowest rated homes, one of which is that you are not allowed to rent out the property. Right now and as of January 1 of this year, the upper consumption limit is 450 kWh per square meter per year. Go above this and the home becomes ineligible.
This number is also planned to reduce over time:
January 1, 2023: Rental ban on properties with G+ energy label
January 1, 2025: Rental ban on all properties with G energy label
January 1, 2028: Rental ban on all properties with F energy label
January 1, 2034: Rental ban on all properties with E energy label
Now here's what this is thought to mean for overall rental supply:
By 2028, 5.2mn homes rated F and G, or 17 per cent of total housing stock, will become ineligible for rental. By 2034, all E properties will also be excluded, amounting to about 40 per cent of homes.
This raises an interesting question: Is it more important to have energy-efficient homes or to have greater overall supply? Now obviously the goal and ideal scenario is both; lots of affordable homes that are also energy efficient. And presumably, one of the objectives of this rental ban is to stick/carrot owners into investing in energy measures. But it's not exactly obvious as to how many owners will be able to renovate their homes in time, and how many homes will become ineligible for rent. This will be an interesting policy to watch as it plays out.
