Tine Steen Larsen believes that the client’s focus and ambition should determine which certification is relevant for a particular project.
“If the idea is ‘only’ to save energy, then building a passive house is fine. However, if the total cost of ownership is also a factor, then it is necessary to choose a sustainability certification scheme such as DGNB which covers social, environmental and economic sustainability, she explains.
“In my experience, consultants are well acquainted with the different schemes. However, many clients are too cautious and prefer to do what they always have done – perhaps because they have heard stories that certification is expensive. I think that some of the prices which I have heard mentioned have been wildly exaggerated. The cost of certification is only a fraction of the total project price and is a cost which should more than pay for itself when you think of the increased quality achieved,” says Tine Steen Larsen.
