The Real Estate Norm (REN) is a method that, already since 1991, enables objective discussion about the quality performance of existing or new to build real estate. The Foundation aims to promote the conservation, enhancement, training and promotion of a user-oriented standard for capturing and measuring unequivocally accommodation performance of locations and buildings under the name Real Estate Norm (REN), as well as all that is related or maybe conducive to that end.
In the early nineties the three initiators of the Real Estate Norm (REN), real estate broker Zadelhoff Makelaars (now: DTZ Zadelhoff), project management organization Starke Diekstra (now: ARCADIS Netherlands) and real estate consultants Jones Lang Wootton (now: Jones Lang LaSalle), have concluded from their daily practice that there is a growing demand for a tool that would enable the objective comparison of the quality of (office & industrial) locations or buildings. The REN-norm is the leading pioneer of a de facto standard for assessing real estate quality, in the sense of fit for purpose. Main founding fathers are late Frans F.A. Diekstra BSc (*30-03-1955 †11-05-1995) and René P.M. Stevens MSc Arch/MBA.
