Our Solution

The team will carry out and evaluate a modular solution that will be applicable to wide range of buildings. Our model building for the Solar Decathlon Europe 21 competition will be student dormitories of Charles University in Prague called “Větrník”.

The team will construct and test the extension unit, that will reach the Passive House level, the replaced components in refurbished part will be of similar quality. The structure composition with insulation will respect real limits on site, respectively on the rooftop.

There will be used a balanced ventilation with heat recovery of the highest overall efficiency in the FIRSTlife unit. On new parts, the building integrated photovoltaic systems will be used; at the existing roof, a building applied photovoltaics will be designed. The installed power will be calculated in alternatives to support the overall energy management of the building, including electromobility. Droughts and city heat island are the issues today in urban area, thus the sustainable rain water management and greenery application will be essential part of the design.

An extra attention will be paid to the elimination of overheating risks of newly designed part with lightweight construction. The goal is no need for active cooling. It will be reached by considering reference data, application of passive measures for minimizing active, i.e. cooling operated via already installed ventilation systems. The climatic data in prognosis for future 30 years. Intelligent control system.

Preferably, the renewable materials will be used for the construction (wood-based construction element, thermal insulation), in general preference of materials with small carbon footprint, which will be separately assessed. The availability of these materials is very high also because the bark beetle calamity in the Czech forests. The exploitation and the use of the harvested calamity wood is very welcomed by the society as a step towards managing the calamity. This aim will help us to reach the overall carbon neutrality of FIRSTlife project.
