Cool*Alps - TAB goes Green Deal.


More frequent heat waves are expected to lead to a signigicant rise in energy demand for cooling buildings. However, the air-conditioning split units that often equip buildings further aggravate the problem by generating waste heat. Cool*Alps aims at improving the climate change adaptability and energy security of the Alpine region by supporting the diffusion of innovative Thermal Activated Buildings (TABs). They enable CO2-free heating and cooling with one system and make settlements more flexible and resilient to extreme heat periods. Cool*Alps will leverage their great potential by developing the competences and supporting decision-makers in implementing TABs.

Climate scenarios indicate a significant increase in heat waves and extreme weather events in the Alpine region. Especially in the Alpine region, more and more heat days are being recorded, which leads to a significant increase in the building cooling energy demand. At the same time, the expansion of renewable energy brings new challenges in energy supply security due to the volatility of production and raises the need for storage options. Currently buildings are increasingly being equipped with climate-split devices, which further exacerbate the microclimatic problem of the environment with their waste heat. With thermal component activation (TAB), a technology is available that enables largely CO2-free heating and cooling: the components store energy when it is available in a climate-friendly and cheap way and release it again with a time delay. This flexibility can make settlements more resilient to extreme heat periods and make a direct contribution to energy security. TABs have been increasingly implemented in the alpine region in recent years, but the great potential of cooling as well as storing renewable energy has been insufficiently utilised. This is primarily due to a lack of knowledge on the part of planners, adherence to existing building practices and a lack of funding.

The overarching goal of the project is to improve the adaptability and resilience of buildings and settlements in the Alpine region. A package of resources enabling sensitization and knowledge transfer for the planning of thermally activated buildings and settlements in the ASP programme area will be provided. A TAB toolbox includes the following four dimensions: a planning guide, a proposal paper for TAB fundings and improvement of legal framework conditions, a pool of experts and the Innovation map TAB Alpine Space, with the aim of sensitizing and increasing the competences and knowledge exchange of builders, planers and political decision-makers.

The hub of this capitalisation project is the existing online tool "Innovation Map TAB" of Salzburg Bavaria region (, which will be rolled out to the whole of Austria, Southern Germany, Northern Italy and Switzerland. Currently there are different approaches and strengths: In Southern Germany and Northern Italy, mainly commercial buildings are being implemented with TAB, in Austria there exist initial experience with subsidies in residential construction, in Switzerland innovative processes for concrete recycling are being developed. In the building sector, innovations are strongly determined by the radius of action. Due to the transnational approach of the project, the project partner countries can benefit greatly from each other´s technical and normative experiences. Common to all regions is the need for practice-oriented training, best practise projects and an active exchange among experts. The planned measures should lead to innovation impulse and an accelerated implementation of this key technology. The spatial proximity of the project regions, the similar climatic conditions and the supra-regional electricity market are strong drivers and guarantors for maximum synergies of a joint approach.
