IEA SHC Task 59/EBC Annex 76: Deep Renovation of Historic Buildings - Towards lowest possible energy demand and CO2 emission (nZEB)

The goal of Task 59 was to document international best practice examples (knowledge base), develop a multidisciplinary planning process, and develop holistic retrofit solutions for historic buildings. As a knowledge base, the Historic Building Retrofit Atlas (www.HiBERatlas.com) emerged from the project. In the HiBERatlas more than 55 best practice examples are documented. In addition to the management of Subtask A (Knowledge Base) and Subtask C (Conservation compatible retrofit solutions & strategies), innovative technical and organizational retrofit solutions, which have already been applied in national demonstration projects and tested in practice, have been incorporated and further developed through the Austrian participation.

Short Description

From an economic point of view, the preservation of our historic building stock, which represents around a quarter of the building stock in Europe, can only succeed if it´s future use is secured. Still, renovation solutions and technologies must be found that make it possible to preserve the historical and architectural values while at the same time increasing comfort, reducing energy costs and minimizing environmental pollution.

The goal of the project was to identify good approaches and best practices and to promote innovative solutions that are compatible with preserving the character of historic buildings. For this purpose, innovative renovation solutions were documented and further developed with regard to both the building envelope (in particular methods of internal insulation) and building technology (e.g. ventilation and solar technology).

Within the framework of the Austrian participation, results and findings were compiled in Subtask A and C in particular. As part of the development of a "Knowledge Base" in Subtask A, innovative renovation solutions from Austrian demonstration projects were incorporated into the HiBERatlas (www.hiberatlas.com). The main objective of Subtask C was to identify, evaluate and, if necessary, further develop rehabilitation solutions and strategies for historic buildings. These solutions took into account elements of the historic buildings that are worth preserving, that meet energy efficiency goals towards lowest possible energy demand and CO2 emissions (NZEB), and are available for comprehensive, integrated rehabilitation concepts and strategies.
