Nowadays European legislation requires all new buildings to be nZEB by 2020. This requirement is needed to follow the Kyoto protocol. As the law has come into effect recently, nZEB concept has not been developed thoroughly yet. As Russia signed Kyoto protocol as well, such requirements for energy performance of buildings can be expected in future.
Aim of the work is to find suitable energy saving solutions in HVAC-systems, especially in ventilation and air conditioning. These solutions should provide good indoor climate and comfort of occupants. Office buildings are in focus in this work.
In the first part of the work existing office buildings from Central and Northern Europe were studied. Their envelope properties, used systems and systems’ performance were studied and descried, so to have a possibility to estimate possible parameters for Russian climate.
In the second part different energy saving solutions found in studied cases were described and possibility and rationality to use them in Russia were assessed. Also on-site energy production was dealt with.
In the third part results of energy simulation are submitted. The results allow estimating possible energy performance of buildings in Russian climate.
The conclusion is nZEBs in Russia are possible, but they require more energy than in Central Europe. All the measures decreasing heating and demands like HRU, airtight envelope with low U-value and use of free pre-heating/pre-cooling should be done. SFP-value should be low. And сhilled beams as cooling distribution system to the rooms should be used.
