Monitoring

The monitoring of the VGTU main building started in March 2006. The conclusions of an energy audit (performed in 2002) showed that 14-16 °C was the average temperature in premises during a heating season.
The indoor air temperature increased by 2-4 degrees after replacement of windows, insulation of roof and renovation of the thermal unit. Now the indoor air temperature meets the requirements. However, the analysis of volume flow, air velocity and relative humidity shows that current values are lower than those of specifications.
Insufficient speed of the indoor volume flow determines lack of oxygen. As a result, indoor hygiene conditions are bad, people feel worse and their productivity decreases. It was possible to compare the data on energy consumption before the renovation and during the renovation.
In summer of 2004, the windows of the main building were replaced. In autumn of 2005, the roof and walls of the semi-basement were insulated. In 2003, the heating energy consumption was 920,000 kWh, and in 2005 already 532,000 kWh, i.e. it decreased by 42 %. In 2006, the heating energy consumption made up 547,000 kWh. Compared to 2003, the heating energy consumption decreased by 41 %.
In 2005, electricity consumption decreased by about 16 % compared to 2003, and compared to 2004 by 26 %. The level of pollution was measured in the environment of VGTU in 2006-2007: noise pollution (dB), CO pollution (ppm), particular mates pollution (particle pollution) (mg/m3) . A forecast of pollution (noise pollution, dB; CO pollution, ppm) in the environment of VGTU for the year 2010 is provided.
