Abstract

Ventilation with recuperation is a means of reducing heat consumption per square meter below 50 (kWh/m2) in Latvia through proper project design and trained personnel.

The aim of this research is to show necessity for a ventilation system with recuperation.  This research would further permit preparing recommendations for responsible decision-makers. There are no regulatory enactments that would provide ventilations indispensability during the renovation process in Latvia. The recommendation for ventilation with recuperation should be incorporated during the renovation as a mandatory requirement in Latvia.

Renovated buildings with European co-financing in Liepaja city have been used as a research basis. Different renovated building groups are compared: those without ventilation, with ventilation, ventilation with recuperation. Each one of these building groups will have more than one object. The obtained data will be heat consumption per square meter (kWh/m2). It is not possible to achieve good results with badly designed projects as well as with non-trained personnel, therefore this system is quite often either not used or ignored. Ventilation with recuperation is to be a mandatory requirement in renovated buildings.

During the research it has been realized that the available information is not sufficient to compare renovation processes in other countries of comparable climatic conditions.

It would be preferable to meet researchers working on similar themes to be able to share mutual experience and to promote co-operation in this field.
