Having more sustainable buildings should concern us all. I understand that there are many people who do not think like that but there is no other. This company says it is specialized in energy efficiency. The truth is that when they came to make us a proposal to change the boiler they also explained to us how much we could avoid polluting gases. I like this kind of detail because it is how it should be, since we are loading the planet.
