Description
The project aims to implement a series of activities that will contribute to the realization of energy efficiency in two public buildings, which house kindergarten “Radost” and kindergarten “Slantse”, as well as creating conditions for their transformation into buildings with close to zero consumption of energy.
The buildings were selected on the basis of the following features: an acute need for energy renovation, large capacity and high attendance, as well as their strategic location. Both buildings will be fully isolated, windows changed so that they can reach class A of energy efficiency. In addition a RES will be installed: The heating of the "Radost" kindergarten will be carried out through the use of a combination of two types of renewable energy sources - highly efficient heat pumps and a photovoltaic; in “Slantse” kindergarten only photovoltaic of 10.5 kWp is envisaged.
The main activities include:
- Implementation of energy saving measures in the buildings of kindergartens ''''Slantse'''' and "Radost";
- Author and construction supervision,
- Exchange of experience ,knowledge and best practices at management and expert level, publicity, audit and project management.
The target groups of the project are the residents of the city of Vratsa and in particular the users of the two buildings - children, teachers, educators, support and medical staff. Expected results of the project includes full environmental friendliness, high level of efficiency up to 96%, a quiet and safe environment and saving natural and financial resources. The project proposal of the Municipality of Vratsa corresponds to the priorities for the future of the European Union - "Strategy for the use of hydrogen for climate-neutral Europe", which defines hydrogen as a "key priority for the implementation of the Green Deal and the transition to clean energy."
Summary of project results
The project aims to implement a series of activities that will contribute to the realization of energy efficiency in two public buildings, which house kindergarten “Radost” and kindergarten “Slantse”, as well as creating conditions for their transformation into buildings with close to zero consumption of energy. The buildings included in the project were selected on the basis of the following features: acute need for energy renovation, large capacity and high attendance, as well as strategic location.
For each of the two kinder gardens were implemented the following measures:
Thermal insulation of external walls and vertical enclosing elements of the roof with EPS insulation was made. Thermal insulation with XPS, cement mortar and waterproofing was made on the roof of the building.
The old windows were replaced with new PVC windows with triple glazing.
The old radiators, vertical risers and distribution pipelines were replaced in all rooms. The new radiators are standing fan convectors equipped with temperature sensors, regulating and shut-off valves. Inverter compressor-condensing units (VRF) with microprocessor control of operating mode were installed.
For kinder garden Radost - A photovoltaic power plant for self-consumption with an installed capacity of 30kW and an active power output for self-consumption of 3okW was built on the roof of the building. For kinder garden Slantse - A photovoltaic power plant for self-consumption with an installed capacity of 10,5kW and an active power output for self-consumption of 10,5kW was built on the roof of the building.
A monitoring system has been implemented, which includes 4 measurement points, three of which measure electrical energy and one measures thermal energy.
Radost kindergarten: 118 children in Radost kindergarten and 24 pedagogical and non-pedagogical staff. Kindergarten "Slantse": 125 children in kindergarten "Sun" and 22 pedagogical and non-pedagogical staff.
Savings expected:
Kindergarten Slantse - 14 420.25 euro / year; 323,04 MWh/ year; 381.18 tons of CO2 eq.
Kindergarten Radost - 42 938.57 euro / year; 996.47 MWh / year; 1 175.83 tons of CO2 eq.
Summary of bilateral results
Improved bilateral cooperation with interested stakeholders in the field of energy efficiency to present good practices and future development of the city and the municipality in this regard.
