||This article describes a new method of collecting and utilizeing the informationneeded for renovation of existing buildings. The method is called the RENO-systemand it has been developed in Tampere University of Technology. The most remarkableproperties of the system are the fully three-dimensional model of a building linkedtogether with a relational data base management system to store material and otherattribute information during on site surveying. In the system development specialattention has been paid to eficiency: producing the three-dimensional model of abuilding is almost as cheap as producing the two-dimensional drawings by conventional methods. The new method can also be used solely for room and material inventory.The three-dimensional CAD-program running together with the relational database management system enables effective processing of the information. TheRENO-system can generate graphical information suitable for the most commonCAD-programs and the data base interface uses SQL-standard, from which theinformation can easily be transmitted to other programs. Of course the three-dimensional data can not be processed with a two-dimensional program, but in general theRENO-system can produce renovation information in any form required by customers.The result of this research defines the data model to input the physicality of spaces.Also the result involves the definition of the surveying method for source informationprocurement in existing environments regardless of whether the object to be modelledis a building or part of town.
