Passive houses are a thing. Everyone should be on board for better built homes. Better to build it right and cry once than to cry every time you get your utility bills. Most homes though are absolute dog shit and leak as much air as an entry door would left open if not more. Mandating current homes or rentals to be renovated to new standards wouldn't be feasible if that's what their objective is. I'm certainly not going to read through that shit to find out but I suspect some falsehoods are being injected.
"What does energy rating D mean?"
It means you live in a shit house or you have a heat pump.
