Energy saving, consultancy and training in Latvia. Energy savings in public buildings. Audit of: The Ministry of Education, Riga. Fianal report

摘要

The buildings where the Ministry of Education is located are in fairly good condition. To improve the building envelope it is suggested that the floor over the basement should be insulated underneath with approximately 100 mm hard mineral wool, the roof should be insulated with at least 100 mm mineral wool, insulation-boards with gypsum should be fitted on the outer walls and all windows and doors should be adjusted and/or repaired. They should also be sealed and the wood should be treated with protective coatings. To improve the technical services, emergency measures are to re-build the mixing loops in the boiler room with an electronic valve and a circulation pump, to build a mixing loop at the guest house, so it will be possible to make a night and a week-end set back at the ministry, to repair, or install if necessary, new valves on the radiators and convectors, to insulate all the un-insulated pipes and valves in the basement and to improve access to the boiler room. The boiler room should be tidied and dried out and new pipes should be installed connecting the district heating systems to the buildings. (AB).
