Energy Assessment of the Civic Building
Otrubová, Sára ; Maurerová, Lenka (referee) ; Vendlová, Lucie (advisor)
The bachelor thesis deals with the creation of the energy performance certificate of the municipal office building in the village Tvarozna. In the theoretical part it focuses on the European directives on energy performance, their analysis and the way they have been included in the legislation in the Czech Republic and marginally also in Slovakia. The calculation part consists of the analysis of energy needs and flows of the building; the analysis of the specified object; and the proposal of energy saving measures to improve the energy status of the building. The proposed measures are assessed from the energetic and economic point of view in the conclusion of this part. The design part includes four energy performance certificates for the building. The first one is based on the baseline condition and the remaining three are alternatives to the proposed measures.

Heat supply for water heating and underfloor heating is provided by a heat pump. Excess water from extensive green roof leads into the sewer system and a stormwater storage tank with a volume of 5m on the northwest edge of the plot. Afterwords, rainwater is discharged together with prefiltered sewage water into the combined sewer. Electricity is provided by a public network. Forced ventilation is provided by ventilation unit using flexible ducts installed in suspended ceiling. Ventilation is used only in living areas, bathrooms, and closet. The system has supply and exhaust ducts for air circulation connected to the distribution boxes and ended by vents with adjustable airflow . The ventilation unit with heat recovery and an air flow rate of 285 m/h is installed in utility room. Air exchange between the ventilation unit and exterior and ventilation unit and distribution boxes is provided by aerfoam ducts. Energy Performance Certificate is A – very efficient.
