As a conscious counterpoint to the increasing automation of buildings, the objective of this project is the transnational and coordinated analysis and development of the “low-tech” building concept without having to forego high energy standards, as well as the extensive reduction of CO2 emissions. What is to be understood as low-tech buildings in the context of the project are premises that are designed in such a way that the technical, energetic and financial input is kept as low as possible, with energy consumption being is as low as possible in operation. In previous years, the legal requirements for energetic building quality have increased in all countries. This has led to lower heat transfer to the shell of the building and for ventilation in new buildings. Besides this, the development of new building materials has enabled many new types of construction. However, the demands for comfort from users, with regard to temperature requirements, summer heat protection and the capacity to control these has not always been implemented adequately. This shortcoming is frequently compensated by complex and multifaceted building technology. Many technical components are time-consuming to control, use increased grey energy in their manufacturing and increase the construction costs as well as the energy requirement of the buildings. They therefore run contrary to reasonable climate protection. As moveable electrical and control-intensive building components have the lowest lifespan and therefore have to be changed several times and maintained regularly in the life cycle of a building, reducing the building technology to a necessary and reasonable level can make a relevant contribution to the discussion regarding affordable, energy-efficient construction and living. Low-tech measures and versions can be found thanks to the insights gained in the specialist group, the existing buildings analysed and the accompanying pilot buildings. These offer the same benefits and therefore lower construction and subsequent costs with reduced technical input. Although the legal framework conditions, the funding options and the requirements for energy consumption differ in the countries around Lake Constance, there are major overlaps in the climatic conditions, cultural roots and typical users. A coordinated approach around Lake Constance combines the competences of the partners, avoids parallel development and supports the working out of common solutions. The strategic objective of the project is the long-term and sustainable reduction of energy consumption in the building sector for new builds and existing buildings, with critical discussion regarding building technology and control elements. The aim is to create climate-friendly buildings with a high level of comfort, low energy requirements and above-average value retention in the long term based on to construction methods that are adapted to climate change as well as a high level of robustness in operation. The entire life cycle is looked at with regard to the structures of residential as well as non-residential buildings. At the start of the project, a transnational grid of requirements for energy-efficient low-tech buildings is drawn up by a specialist group consisting of all the partners, which takes account of the specific requirements of the countries. Existing energy-efficient low-tech buildings in the Lake Constance area were identified and presented in a catalogue, with a description and comparison of the various criteria for evaluation. Based on the catalogue, each partner also monitors, documents and validates two pilot buildings each at the planning and construction stage in their project area. The result of this is documents and recommendations for the expedient requirements of new buildings and general renovations intended for building and public planning authorities, in which the features for forward-looking, climate-friendly buildings for the Lake Constance area can be presented. These serve as information for private builders and building authorities with regard to modern construction standards with high comfort levels, low energy requirements and above-average value retention in the long term, which can be used as recommendations for construction and legal planning specifications by the public authorities.
