Sixty percent of all of the residential space in the Baltic states is made up of multi-apartment buildings constructed during Soviet industrialization, approximately: 20,000 in Lithuania, 18,000 in Latvia and 17,000 in Estonia.
Supported by the European Union through the financial instrument JESSICA (Joint European Support for Sustainable Investment in City Areas) renovation models conceived by the governments of the Baltic states have attempted to extend the life cycle of the multi-apartment buildings and most importantly reduce the amount of energy imported solving geopolitical dependency.
Renovation models provide financing schemes that channel the flow of money paid for energy resource imports towards repayments against loans for renovation materials, thus stimulating the building industry while reducing the outflow of capital from the country and softening geopolitical tensions.
The renovation strategies offer budget solutions for uniform insulation over bare large concrete panel housing on a regional scale. Strategies are efficiently simplified making them adaptable to every individual scenario of each multi-apartment building.
The smallest actor in the renovation process is a single multi-apartment building. The renovation strategy descends the understanding of “community” from above implicating the private owners to address the existing arrangement of their housing collectively—communities that do not necessarily have many things in common.
Three facades:
Ventilated facade: Mineral wool PAROC Extra, Mineral wool PAROC Cortex (windward), Aluminum profiles, Fiber cement panels, Rivets, Plastic pins. A ventilated system is the most popular facade due to the wide range of fiber cement panels on offer and the possibility to replace parts in case of damage.
Non-ventilated facade: Polystyrene foam, Cement, Reinforcement net, White stucco, Paint. Non-ventilated system is significantly less expensive, but harder to install, wears quickly while being difficult to repair.
Foundation insulation: Styrofoam, Hydro Insulation, Drainage board, Aluminum studs.
