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 …
Cultural heritage objects and interiors are found not only in museums but also in historic buildings, often with less climate control. The indoor environment in such buildings may be colder and more humid, and can fluctuate. The research presented here …
We proudly present the postprints of the third International Conference on Energy Efficiency in Historic Buildings, held in Visby, Sweden September 26th to 27th, 2018. The conference was organized jointly by the Swedish Energy Agency, Uppsala University and the Swedish …
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, …
