Jauna Forstate is a district of City of Daugavpils. Value of the property has increased annually. Owners see the potential and are interested in refurbishment. Socio-economic problems have increased and there is a main barrier – costs and refurbishment co-financing by government.
The district contains 95 residential buildings and 17 non-residential buildings: School, kindergartens, centre of education and privately owned commercial buildings. Residential (multi-family) buildings are the main energy consumers in the district. All buildings were built before 1994 and they are connected to central district heating system. Their technical condition is good, but the energy consumption is very high (about 160 kWh/m²a).
The technical development included an analysis of the energy saving potential by refurbishment of buildings. The aim was to find the most efficient technologies to reduce the heating energy demand of the buildings. The most important and popular activities to improve the energy efficiency are refurbishment of building envelopes (wall insulation, roof insulation). Changing windows activity made some problems. Old windows with wooden frames can be changed only at public areas (entrance, terrace etc). To invest in window replacement is not economically good solution for those flat owners who has changed old windows before. Two buildings in Jauna Forstate have already been refurbished, Fig. 26. Buildings construction stopped in the beginning of 1990’s. Construction continued with total refurbishment in 2008-2009 by investor. All flats are sold at this moment.
The solar potential in the district is very high and neighbour buildings do not shadow the roofs. There is plenty of space on roofs and facades to exploit possibilities of renewable energy.
Demo Site Expected Impact
All projects are in development stage. This is only ideas how to minimize energy consumption, introduce RES technologies.
The main objective of MODER is to increase business of engineering companies, energy managers and consultants in supporting municipalities and building owners in European and global markets for the refurbishment of buildings at district level. Several improvements are required to reach this objective: Exceeding barriers concerning the reduction of energy demand of buildings, new tools that enable the assessment and design of refurbishment and new business and process models for efficiently execute the refurbishment of buildings at district level. Technical objectives of MODER are to develop, demonstrate and mobilize tools, services, process models and business models
