Abstract
The energetic and comfort optimization of these buildings, however,is not yet generally accepted and therefore a more delicate discussion. (Too) often these buildings are (too easily) exempted from adaptations because: the reconciliation of energy savings / comfort optimization and heritage values seems too difficult or even impossible, the(unqualified)application of new techniques could (possibly) do more harm more than good,the behavior and ageing of new techniques are often not yet fully understood, investigated or well-known,it is generally accepted that the original state should be restored as much as possible by traditional materials and construction methods.However, one needs to be aware that adapting buildings and heritage to meet the actual needs of its users with evolving materials and techniques has always happened. Conservation of heritage in one certain original (?) historic state, makes that,in some cases, these buildings no longer meet present-day needs and comfort aspects. Whereas it should be acceptable for historic buildings only to meet the present-day standards partially, the users’ comfort must be taken into account in order to assure the future use of these buildings. After all, it is common knowledge that unused buildings decay rapidly, and uncomfortable and energy consuming buildings are not likely to be used. Such an approach only would condemn them to be lost...Our generation should make the decision to preserve our built heritage in a way it reflects and is adapted to the economic,societal, environmental, comfort and energy context of today, while ensuring the absolute preservation of the heritage’s intrinsic values. After all, an optimized preservation and use of heritage buildings offers several opportunities such as:a more attractive use and better occupation of these buildings by assuring a reduced energy bill,the improvement of the indoor climate (and reduction of fluctuations in temperature and air humidity) would enhance the conservation of the building, its structure, finishing materials, interior decoration and collections, a more constant maintenance of the occupied buildings minimizing the risks of decay due to condensation, corrosion, biological attack, deformations, frost and salt damage ..., this way reducing the need for large restoration campaigns,and last but not least, a contribution to the reduction of greenhouse gas emissions by this collection of buildings.All of these aspects would lead to an improved use and preservation of our heritage buildings, as used buildings remain preserved considerably better than unused.Yet, it is essential that this thermal and comfort optimization of heritage buildings must be approached in a holistic way. Certainly for heritage buildings the main focus may not be the maximisation of the energy consumption / greenhouse gas emission reduction, but should always be the search for an optimal intervention respecting the constraints of the heritage values, as these values make the historic buildings that form the core of our European cities and countryside so special. Luckily, in the last years the above mentioned approach and considerations are more and more accepted throughout an increasing group of (heritage, comfort and energy) experts and governments. One can notice for example the roadmap of EeB PPP (Energy Efficient Buildings Public Private Partnership)and several “Horizon 2020” calls in which energy intervention strategies and solutions for energy renovation of historic buildings are identified as a priority, several finished and ongoing nationals and European projects that focus on the interplay of energy efficiency and heritage preservation, or even the workgroup 8 “Energy efficiency of historic buildings” of the CEN/TC 346 on the “Conservation of cultural heritage” that is drafting a European standard(EN 16883:2015) entitled “Guidelines for Improving the energy performance of historic buildings”. All of the above mentioned considerations, evolutions, needs, thoughts and the implication, expertise and concerns of the BBRI Laboratory of Retrofitting on this matter formed the basis for the Belgian Building Research Institute to organize and host the second edition of the International Conference on Energy Efficiency and Comfort of Historic Buildings in close collaboration with the concerned public institutes from Brussels(DMS–the Brussels Monument and Sites Directorate), Flanders (Onroerend Erfgoed–the Flanders Heritage Agency) and Wallonia(DG04-Patrimoine–the Walloon Monument and Sites Directorate)from October 19thto 21st2016at the Royal Library in Brussels.After a first edition organized by Casas Históricas y Singulares and Ars Civilis in Madrid (2014), this second edition will gather research groups, governments, building practitioners, product developers ... working on topics related to the generation,transfer and application of knowledge, methodologies, materials and techniques to optimize the interplay between improving energy efficiency and comfort on the one hand, and preserving the heritage values of our historic buildings and cities on the other.The EECHB2016 conference therefore brings together international experts and stakeholders, sharing state-of-the-art developments and their latest experiences, results, experiments, etc. around the following six themes related to the optimization of historic buildings: 1.Boundaries and obstacles, 2.Using and improving energy models, 3.Training and education, 4.Interventions related to (a) systems and indoor climate, and (b) materials, 5.Monitoring and feedback, 6.Governance issues.
