Project | Energy concept

The climate concept stems from the basic idea of the design: to use the traditional means of corresponding climatic region. Towers for ventilation with evaporative cooling and the use of thermal mass in the interior are two of those traditional examples.

The team combines this way of traditional thinking with the modularity and brings it in the draft in form of arrangement of living-modules and air gaps. The climate-concept consists of three different components. First, the building and its hull are optimized for the resulting heating and cooling loads to be minimal. The second package of measures consists of passive concepts that contribute with minimal operating power necessary to condition the building. Finally an innovative and energy-efficient heating and cooling technology is applied to cover peak loads. All of the following components are separate systems, which act dependent on each other shaping the design of the building. It was important to exploit all the passive opportunities in design as fully as possible, so that the active systems would be used only as backup during the respective temperature peaks in winter and summer.

The combination of traditional principles and modern materials and technology is also found in the interior. The phase changing materials (PCM) increase the thermal mass of the wooden modules. In addition, a ventilation unit with heat recovery ensures the minimisation of ventilation heat losses. However, existing active systems should be used only as backup systems in the respective temperature peaks during winter and summer. Passive possibilities are exhausted in design as far as possible.

To meet the low but, of course, still available energy needs the whole building hull is solar-activated. The roof and east and west facades will be fitted with solar panels to generate electricity acting like a second hull. Simulations show that after a year not only the power needs of the building will be covered, but there will be even additional energy to feed in to the net. This way our building will be a “plus energy” house.

The facades are covered with PV modules, which provide certain transparency. Therefore the modular and layered character of the building is seen from the exterior.

Together with the energy tower this establishes a high flexibility and exciting spatial relationships.
