Renovation of Office Building
The design and success of renovation construction depends on a precise building condition estimation. A methodical system that supplies an exact condition estimation of the building prior to renovation should be developed. At present, designers lack thorough knowledg of building physics, especially in the areas of heat, moisture and sound insulation. Fire safety regulations also cause design and construction problems. In the field there seems to be a lack of research and practical feedback knowledge. The study was carried out in 1983 on a renovated office building called Air-Ix Talo in Tampere. The renovation consisted mainly of window constructions, HVAC, piping and electrical installations. The energy ecouctions, HVAC, piping and electrical installations. The energy economics of the building was studied. The total specific energy consumption was 60 kWh/m/sup 3/ a, which is 15% below the average value third of the total energy need. The indoor air flow supplied at a rate of 18 cu dms per person. It was found that at a rate of 10 cu dms per person the indoor air became fouled with carbondioxide concentrations exceeding 1100 cu cm/cu m. However, at any rate of outdoor air flow, the particle concentration was found to be below outdoor air levels due to circulation air filters. The mixing ventilation installation consisted of constant air flow devices. At full air flow the air exchange effectiveness did not reach complete mixing. When operating at half power the supply air flow short circuted. This resulted in a reduction of the air exchange effectiveness by between 10 to 20 percent under the value of complete mixing.
