We will talk about the human population first. An independent study in 2000 carried out in UCD demonstrated that hollow block construction could be insulated to comply with higher thermal performance standards. I am more familiar with the two-block cavity wall, as Senator O'Toole called it. The wooden house type of structure, often referred to as American-style houses, are very popular now, but they are very expensive, as the Minister of State would appreciate.
