Fairly agree with you, in the "public versus private" battle, a little commitment makes it easier to move the public sector than the private sector
the nerve of the war being money it is easier to do something with public money since this money does not belong to the decision maker
the title of the subject speaks of business when you only speak of tertiary and your examples are only on buildings
there are incentives to save energy (it is not a question of energy saving). ex: the variators are subsidized by edf, this is how in the company where i work we have put them everywhere, the gain is enormous and the return on investment very fast (less than a year).
our managers give us the green light on any investment whose return is made over less than 3 years (which company today can be envisaged over the longer term?)

for pv in business even with aid it is depreciable and considering the powers we need it would be really ridiculous.
and then the pv in the public c is often powder in the eyes: we install some panels for the fun and we install 3 or 4 halogen of 5000w to light up the facade of the town hall or the church !!
I have installed a France Geothermal heat pump which works perfectly, but does that mean that the world must behave like me?
we also have to install but just for the sake of economy and it is not part either of enr
