1. GENERAL DESCRIPTION
The Vackor kindergarten is located in the 18th District of Budapest. The kindergarten has been built between 1978-1982 using lightweight construction. Currently the energy performance class achieved by the building is the lower one. The goal of the renovation is to reach nZEB target following a cost-effective way in accordance with the EPBD. It is one-storeyed building with an inner courtyard surrounded by garden and with flat roof. This pilot case study is part of the eCentral project.
2. ENERGY RENOVATION STRATEGIES
The Vackor kindergarten will be renovated as part of the nZEB pilot project. In accordance with the preliminary assessment the following renovation is planned to achieve the nZEB target, increasing the energy efficiency performance and indoor quality. Several renovation scenarios were analised, and it has been decided to implement these renovation measures:
- Insulation of the building envelope: walls and roof
- Replacement of windows with triple glazing technology and doors
- Replacement of condensation combi gas boiler
- Installation of wood gasification boiler
- Use of RES, through solar panels installation
- Monitoring and verification of thermal flows
3. FINANCIAL MODEL
The building will be renovated using EPC financing scheme, with carefully defined demands towards the private partner (nZEB compliance, innovation, minimum whole life cycle cost compliance, sustainability standards, public access energy demonstration centre). Green procurement criteria and state of the art technology (RES and RUE equipment), including monitoring and verification tools (smart metering) will be requested in order to bring innovation and latest technical achievements to practical use.
