The primary intent of this research project is to review the current state of knowledge and risks relating to the deep energy renovation of traditional buildings, which have different hygroscopic and thermal behaviors to buildings of modern construction, and which represent approximately 16% of the total housing stock in Ireland. One of the key characteristics of traditional buildings is that they are constructed of solid masonry walls that are ‘breathable’, i.e. the building fabric allows moisture to be absorbed and released cyclically. This form of construction relies on vapourpermeable materials and higher levels of ventilation to ensure the well-being of the building fabric and the internal environment. The term ‘traditional building’ is more comprehensively described in the DEHLG publication Energy Efficiency in Traditional Buildings.
This document provides an overview of the important issues and risks relating to the energy renovation of traditional buildings and directs readers toward credible sources for further information. Building upon the STBA Responsible Retrofit of Traditional Buildings gap analysis report of 2012, the Annotated Bibliography section of this report assembles in one place a list of the statutes, standards, technical documents, academic research and case studies relevant to the deep energy renovation of traditional buildings in Ireland.
This is a fast-moving field of research and since 2012, at least 54 further technical research and guidance documents have been published or revised that examine various aspects of the hygrothermal performance of traditional buildings pre- and post-renovation. Overall, of the 475 plus resources collected during the course of this project, more than three-quarters were published after 2012. The Annotated Bibliography is designed to provide building practitioners with the resources and tools to specify deep energy renovation works appropriate to traditional buildings in Ireland and to help them span the persisting knowledge gaps in practice. Web links to the resources discussed in the text have been provided in the right-hand column of the document. Resources available for purchase are marked in yellow, while those available free of charge are marked in blue.
Further objectives of this research are to identify technical and non-technical barriers inhibiting the effective implementation of energy renovation in Ireland; to identify knowledge gaps and areas for further research; and, based on the evidence identified, to propose future courses of action.
