Cool Alps 
Cool*Alps - TAB goes Green Deal.
News & Events


More frequent heat waves are expected to lead to a significant 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). The latter enable CO2-free heating and cooling with one system and make settlements more flexible and resilient to extreme heat periods. Cool*Alps leverage their great potential by developing the competences of builders and planners and supporting decision makers in implementing TABs.

Climate scenarios indicate a significant increase in heat waves and extreme weather events in the Alpine region. At the same time, the expansion of renewable energy bears 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 due to waste heat. With thermal component activation (TAB), a technology 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 increasingly been implemented in the Alpine region in recent years, but the great potential of cooling as well as storing renewable energy has been insufficiently exploited. Reasons for that include primarily lack of knowledge on the part of planners, adherence to existing practices as well as 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 sensitisation and knowledge transfer to plan thermally acitvated 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 for experts and the Innovation map TAB Alpine Space, with the aim of sensitising and increasing the competences and knowledge exchange of builders, planners, and political decision makers.

The hub of this project is the existing online tool "Innovation Map TAB" by the Salzburg-Bavaria region (, which will be rolled out to the whole of Austria, Southern Germany, Northern Italy, and Switzerland. There are currently different approaches and strengths: in Southern Germany and Northern Italy, mainly commercial buildings are being implemented with TAB, while Austria has initial experiences with subsidies in redidential construction, and 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 partner countries can benefit greatly from each other´s technical and normaitve experiences. Common to all regions are the need for practice-oriented training, best pracise 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 for a joint approach.

  • TAB roll-out toolbox

    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. The 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 of builders, planers and political decision-makers.


  • Innovation map TAB Alpine Space

    The created Innovation map currently includes over 80 Thermal Activated Buildings (TAB) from five different building typologies. If you zoom into the map, individual projects become visible.  Each building has an information box with key data on the construction method and special features as well as photos. In addition there is a pool of experts, in which over 110 experts from Austria and Germany who are already working with TAB are presented. The map is the ideal basis to build a network of builders, planners and architects. In addition, interested builders can find experts, which have already experience with TAB. In the Interreg project Cool Alps, the innovation map is being extended across the entire alpine region to make buildings and experts visible in all regions.
