In 2006 Part L2b was born. In it is a requirement that consequential works be carried out when certain large buildings are renovated [based on floor area I think but can't remember off hand].

Basically, a full 10% of the contract sum must be spent on thermally upgrading fabric and/or systems of the existing buildings.

Anyone know what the take up is on this? Are such sums spent as they are supposed to be? Or is the requirement ignored?

In my experience, having worked on several refurbishment projects of late, that the requirement is met more often than not. That said, if you under state the works initially, and add other elements that you intended to do anyway as consequential improvements then it's pretty easy.

Take for example provision of cheap and nasty DX cooling to existing offices to make them more attractive for let. This attracts a consequential improvement so you say you will upgrade the lighting in mitigation (which you intended anyway).

So we get yet another generation of poorly performing buildings that are now even more energy hungry

Good eh
