Grieser Auen - Bolzano
In Bolzano, the Grieser Auen expansion zone is a new urban district that was planned from the outset as a model for sustainable living: optimized in terms of energy, largely without car traffic, and all-around family-friendly. Despite the high demands, the costs had to remain within the usual range to make the model repeatable and profitable for future construction projects. One of the buildings realizes this vision with Green Code climate-controlled ceilings and thermal walls in multi-story residential construction.
In addition to the feel-good factors, the climate-controlled ceiling also has energy benefits that fit well into the ambitious energy concept of Grieser Auen: For example, even small temperature differences in the water flow are sufficient for the climate-controlled ceiling, to effectively heat or cool a room. This in turn enables the efficient operation of a heat pump with a high coefficient of performance. And because the surfaces are heated directly instead of the room air, less energy is lost during air exchange. Due to the direct heat supply, the walls also dry out in heating mode, which prevents mold growth and improves their insulation values. This is because a reduction in humidity of just four percent by volume halves the heat transmission of an exterior wall. This increases the insulating properties of the Green Code thermal walls used even beyond their good U-values.
"The use of prefabricated concrete elements was initiated by the client, who wanted to construct the entire building as economically as possible and reduce future maintenance costs.
