Does Dr. Byrne expect that when you scale up something in a way that is smart, for example, if you do ten houses next to one another, you will get better outcomes? Doing things at individual contractor level - a "one house here and one house there" approach - strikes me as being quite inefficient in terms of what might be possible. I refer to district-based energy as one area, or even the rooftop revolution in respect of solar power. In terms of scale, it cannot just be dotted around the place but done where you will get multiples. What is the SEAI doing in respect of this?
