Measuring techniques and measuring system in a recently started energy saving project.

Discusses an energy saving project managed by a Swedish contractor ABV and sponsored by the SCBR. The project concerns about 500 flats in buildings that are 25-40 yrs old. Uses and applies experiences from theoretical and experimental work of testing air permeability and calculation of ventilation and infiltration. Describes development of some new techniques for measuring infiltration/ventilation. The work has also resulted in a new measuring unit for recording and treating temperature values. Gives an account of the background of the measuring unit and the way it is being used in the project.
