Research and development of cost-effective, high-performance thermal insulation materials for the construction sector has to be focused on their final application. In particular, solutions for refurbishing historic buildings, which represent 40% of the European building stock, have to offer a good compromise between environmental quality, energy efficiency and conservation aspects. In this paper, the experimental assessment of an insulation material based on aerogel technology, recently developed in the European project EFFESUS, is presented with regard to the material's thermal performance, compatibility with historic fabric and reversibility. The overall results obtained in laboratory testing on a real-size mock-up and in a real-world case application indicate that the new material is a promising solution for retrofitting historic buildings, thanks to its thermal properties, easy application, reversibility and material compatibility.

When deciding on the best historic building retrofit, energy savings and thermal comfort can be quantitatively evaluated using an energy model, whereas conservation compatibility is intrinsically qualitative and reflects the perspective of the local heritage authority. We present a methodology that permits finding and comparing optimal retrofits for historic buildings in a multi-perspective and quantitative way. We use an analytic hierarchy process to quantify conservation compatibility by distilling a conservation score from the opinions of 10 experts in the field. This score, along with energy needs for heating and cooling and thermal comfort, are the three targets of a multi-objective optimization aimed at identifying optimal retrofits for a medieval building in the north of Italy, destined to become a museum. Retrofit measures considered were different kinds of external and internal envelope insulation, improvement of airtightness, replacement of windows, and ventilative cooling. The result is a portfolio of optimal retrofits that cover the whole range of conservation compatibility. We show that in the analyzed case heritage preservation is compatible with a four-fold reduction in energy needs at a high thermal comfort level. Even higher energy savings are only achievable at the cost of heritage degradation.

Kirchenheizung. Eine Gratwanderung zwischen Behaglichkeit, Kosten und Denkmalpflege.
Troi, Alexandra (2010)
Open Access
Das Beheizen historischer Kirchen ist eine stete Gratwanderung: Für Besucher soll im Aufenthaltsbereich ein gewisser Komfort erreicht werden, während die Kosten beschränkt und Schäden an wertvoller Ausstattung vermieden werden. Dass dies nicht trivial ist, zeigen vielfältig dokumentierte Schadensfälle, beispielsweise zu Schwärzung an Wänden, Salzausblühungen oder abblätternder Fassung. Eine „beste Lösung“ für alle Kirchen gibt es nicht, sehr wohl aber können Kriterien aufgestellt werden, um den Entscheidungsprozess für eine konkrete Kirche zu unterstützen – so die Ergebnisse dieser Arbeit, die neben Raumklimamessungen in 28 Kirchen und dynamischer Simulation auch ein ausführliches Literaturstudium umfasst. Eine wesentliche Rolle spielt neben Kirchenausstattung, Raumgröße, Außenklima und Nutzungshäufigkeit auch das bisherige Raumklima, auf das sich Gebäude und Inventar - unter Umständen seit Jahrhunderten - eingestellt haben.

Le chiese costituiscono un patrimonio inestimabile di oggetti sacri e di culto, reliquie, opere d’arte, organi, costruzioni monumentali, arredi, decorazioni, non inferiore a quello contenuto in musei e palazzi storici. Questo patrimonio che in seguito viene indicato con il termine beni culturali, va preservato da costanti ingiurie ambientali. I beni culturali sono sensibili alla temperatura e all’umidità relativa e negli anni si sono adattati al particolare microclima locale, ai suoi valori medi e alla sua variabilità. Molte chiese, rimaste per secoli al freddo, ci hanno tramandato numerosissime opere in buone condizioni, ma negli ultimi decenni, dopo che ha preso piede l’uso del riscaldamento, il loro stato di conservazione ha subito un pesante contraccolpo. Sono possibili due strategie di riscaldamento delle chiese: 1) riscaldare l’ambiente destinato ad accogliere le persone (riscaldamento generale); 2) lasciare l’ambiente freddo e cercare di riscaldare solo le persone (riscaldamento localizzato). Il riscaldamento generale ha il vantaggio di utilizzare tecniche tradizionali, ben note; comporta però un grande spreco energetico, ma soprattutto un alto rischio di provocare danni alle opere. Nel riscaldamento localizzato, invece l’utilizzo mirato del calore consente una ridotta dispersione e quindi un basso costo energetico, e soprattutto offre ai manufatti condizioni microclimatiche imperturbate, senza rischi per la conservazione. L’oggetto della presente guida è fornire un supporto scientifico per la scelta e l’uso del sistema di riscaldamento e per ridurre al minimo le conseguenze negative ai fini della conservazione. Il problema nella sua complessità è enorme, date la quantità, la qualità, la varietà e la delicatezza dei manufatti presenti nelle chiese. Questa guida non ha l’ambizione di chiarire tutti gli aspetti della questione, ma cerca semplicemente di far capire a quali rischi per i beni culturali possa portare un sistema di riscaldamento, suggerendo che questi rischi vergano sempre affrontati e discussi da esperti nelle varie problematiche coinvolte.
