In case of public areas, the aim is to change paved surfaces to bright, resp. reflective surfaces with lower solar radiation absorption, which will significantly contribute to reducing the heat effect, as dark paved surfaces reflect only 10-20% of solar radiation, while bright surfaces more than half. The mentioned measure to increase the resistance of public areas to overheating has been implemented on the asphalt surfaces of skating rink in the Mazorníkovo.
To increase the air humidity, reduce the content of dust particles and create a visual and vegetation barrier, vertical substrate garden with perennial plantings has been installed on the one container stands as a pilot project.
In the yard of M.R. Štefánik, where the Museum of Communism is located, an example of a of greening public buildings hes been realized. This provides shading with alternative elements of green infrastructure, specifically exterior vertical greenery. In this yard, part of the walls facade has been greened.
The aim is to ensure cooling of the environment through evapotranspiration of vegetation (release of water from the surface of plants) and evaporation from surfaces, capture of dust particles. Vertical greenery contributes to improvement and healing of the climate, it contributes to increasing the ecological value of the area.
Due to changes in precipitation, especially in connection with more frequent droughts, the town proposed to reduce water consumption by reusing rain and waste "grey" water in the building of the kindergarten Božena Němcová. Rainwater is now collected in surface water reservoirs and further used for irrigation of grass areas in the school premises, which is saving money for the supply and drainage of water (so-called water and sewage). Rainwater irrigation replenishes groundwater supplies and improves the microclimate of the environment through increased evaporation.
For this purpose, the following measures was to purchase under the proposed measure:
- 4 pieces of water collectors with filter: 2 pieces of plastic collection tank with a volume of 300l and 2 pieces of plastic collection tank with a volume of 650l
- 4 drain taps
- 4 roof gutters from the roof with an area of 219 m2
The restoration of the building consisted of:
- the insulation of the perimeter walls of the above-ground floors, the replacement of window and door panels, the renovation of the balcony, modifications to the building's plumbing structures, modernisation of the boiler room and construction of a new gutter sidewalk.
According to the conclusions of the energy audit, the renovation of the building will save CO2 emissions at the total amount of 14.3 t CO2/year. The rate of total energy savings after the implementation of all proposed building modifications is estimated at about 64% compared to the existing solution. In case of these energy efficiency measures, the key indicator planned to make a measurable contribution to achieving the minimum required CO2 reduction target was set on the basis of the conclusions of energy audits carried out for both kindergarten buildings.
