Dr. Miguel Tovar Reaños:

There is a further part of the research I am involved in at the ESRI. We are investigating how much reduction in CO2 emissions one can get by improving the rating of the dwelling. That research is still ongoing so we do not have results yet, but that will come at some point. It is also important to highlight that there are many factors that could lead people to retrofit their houses. To take the case of a person who is renting a dwelling, he is not in a position to ask for grants to retrofit the house because he does not own the house, so this is a kind of market imperfection that exists. Even for people who own their house, the literature shows there is a lot of resistance to investing.
