Mr. Pat Barry:

It is cross-laminated timber, which allows the building of massive beams - up to 22 storeys can be built with solid timber.

There is potential to set criteria for finance. It is not just about the energy efficiency of the homes themselves. The biggest cost for a home buyer is the transport he or she needs to access the home. If he or she needs to own a car it can add up to €1,000 to the monthly mortgage cost. That is not taken into account in a mortgage. If people live where they can walk and cycle, they do not need cars and it is not taken into account in their mortgages. There is great potential to set criteria around all of those factors, such as embodied carbon, transport and energy efficiency.
