As the newly built and renovated buildings consume less energy for heating needs, due to better and thicker insulation, the relative energy consumption for ventilation increases. This leads to necessity for increased effectiveness of ventilation systems, but such systems are …
The indoor climate of historic buildings is governed not only by human comfort but also the desire to preserve these buildings and their interiors. For preservation, relative humidity is the most important parameter, including its amplitude and change rate. To …
Climate change is expected to result in a warmer and more humid climate in northern Europe. Historic buildings with none or primitive climate control will face higher risk of bio-deterioration – mainly due to mould, rot and insects. There is …
Intermittent heating, common in churches, requires higher heating power than steady state heating. With respect to energy use and preservation aspects, the heat up time should be short. Systems for intermittent heating are often designed using rule of thumb estimates …
Indoor climate in historic buildings pose both practical and scientific challenges. There are two fundamental challenges that must be addressed. The first challenge is establishing a proper indoor climate with respect to both human comfort and, above all, conservation of …
Refurbished buildings should also increase their energy efficiency, according with current regulation; however, in case of historical buildings, preservation orders are so strict to hamper usual energy efficient interventions on the building envelope side. As a consequence, in historical buildings, …
Purpose: The addition of thermal insulation into attics along with air-tightening of the ceiling plane is a common first step in making homes more energy efficient. Attic ventilation was introduced decades ago on the assumption that air leakage across the …
The dynamic thermal conditions profoundly impact on the quality of physical, cultural, and social experiences in courtyard spaces. This research aims to identify the microclimatic dissimilarities between courtyards in terms of tempering seasonal–diurnal thermal extremes and enriching ground-level thermal textures. …
Energy efficiency and thermal comfort in historic buildings are very often hampered by preservation needs. This issue is particularly relevant for historical and monumental buildings, which currently represent a large part of the historic buildings stock in Europe. For such …
In the last decade, the European Union promoted several directives dealing with strategies and methodologies pertaining to buildings energy demand reduction. To accomplish fixed targets, a different design philosophy has to be adopted for new buildings construction. Additionally, RES (Renewable …
