Prosumer Cluster Of Single-Family Houses Under The Danish Net Metering Policy, Marijana Larma, Rongling Li, Carsten Rode
International Building Physics Conference 2018
In the energy sector, prosumers are typically houses with rooftop PV. With the drastically falling prices of PV panels, the number of installations is rising. Prosumers can have negative impacts, on power grids especially in the distribution grid. In order to mitigate this effect, and for the own benefit of the prosumers, they can function as groups sharing their resources. A literature overview is given focusing on studies that deal with this issue from the prosumer perspective, showing that many optimization studies focus on maximizing economical benefits and others on self-consumption or related indicators by means of energy management strategies …

Description Method Of Outdoor Climate Characteristics Considering The Comprehensive Effect On Indoor Climate, Xinying Fan, Meiling Sun, Tongke Zhao
International Building Physics Conference 2018
What human and buildings perceived the environmental information is comprehensive information. However, existing indoor environment design methods are often simplified to single parameters for indoor and outdoor environmental prediction and indoor environment design. In order to describe the indoor climate characteristics of the comprehensive impact of outdoor climate, this study uses the ensemble empirical mode decomposition (EEMD) method to establish a multi-parameter integrated outdoor comprehensive environmental information description method based on the information-response theory. The outdoor climate feature description method is applied to the analysis of the amplitude and frequency characteristics of outdoor comprehensive information, which provides a research basis …
Impact Of Indoor Temperature And Co2 Levels On Occupant Thermal Perception And Cognitive Performance Of Adult Female Students In Saudi Arabia, Riham Jaber Ahmed, Dejan Mumovic, Marcella Ucci
Impact Of Indoor Temperature And Co2 Levels On Occupant Thermal Perception And Cognitive Performance Of Adult Female Students In Saudi Arabia, Riham Jaber Ahmed, Dejan Mumovic, Marcella Ucci
International Building Physics Conference 2018
Due to hot arid climate in Jeddah, Saudi Arabia, occupants rely on air conditioning (AC) to provide both ventilation requirements and thermal comfort. It is believed that this total reliance on AC have also a significant effect on thermal sensation as well as cognitive performance of building occupants. Using a multi-variable multilevel statistical analysis, the effects of classroom temperature and CO2 levels on cognitive performance were estimated. Eight neurobehavioral cognitive tests were used to evaluate cognitive performance of 499 female students (16-20 years old). In addition, thermal sensation votes were collected. All participants were exposed to nine different environmental conditions, …
Thermal And Mycological Active Protection Of Historic Buildings On The Example Of The Baroque Residence Of Polish Kings In Wilanów, Robert Wójcik, Piotr Kosiński
Thermal And Mycological Active Protection Of Historic Buildings On The Example Of The Baroque Residence Of Polish Kings In Wilanów, Robert Wójcik, Piotr Kosiński
International Building Physics Conference 2018
Protection of the external partitions of historic buildings is a broad topic due to the limited possibilities of interfering with the structure. Restoration restrictions on prevention in the mycological protection of historic buildings are so large that, from the broad list of possible protective measures, practically only the heating of the nodes and the control of air parameters are practically safe. The reason for restrictions is the lack of possibility of introducing architectural changes and the limited possibility of interfering into the structure of external partitions. A fast method that uses fluorescence was used for quantitative assessment of the mycelium …
The Co-Heating Test As A Means To Evaluate The Efficiency Of Thermal Retrofit Measures Applied On Residential Buildings, Evi Lambie, Marieline Senave, Dirk Saelens
The Co-Heating Test As A Means To Evaluate The Efficiency Of Thermal Retrofit Measures Applied On Residential Buildings, Evi Lambie, Marieline Senave, Dirk Saelens
International Building Physics Conference 2018
In order to reduce the energy use of residential buildings, regional governments in Belgium established, amongst others, mandatory criteria for the energy performance to be achieved after retrofitting. However, due to construction deficiencies, deviating boundary conditions, and nonmodeled physical phenomena and interactions, the actual energy performance may differ significantly from theoretical design value. Several studies indicate this as the performance gap. This paper focuses on analyzing the actual impact of the refurbishment measures applied to a single-family home in Belgium. Hereto, in-situ measurements assessing the building envelope’s thermal performance, described by the overall heat loss coefficient HLC [W/K], are performed …
Do Interface Resistances Matter In Historic Masonries? -Analysis Based On Xray Tomography And Heat, Air And Moisture Modelling, Klaas Calle, Nathan Van Den Bossche
Do Interface Resistances Matter In Historic Masonries? -Analysis Based On Xray Tomography And Heat, Air And Moisture Modelling, Klaas Calle, Nathan Van Den Bossche
International Building Physics Conference 2018
For hygrothermal simulations it is often advised to homogenize masonry wall constructions into a 1D solid brick construction. This saves computational time, but it may lead to an underestimation of moisture related risks. Some literature states that the impact of mortar is negligible, but no specific attention was paid to historic masonries, which often have high absorptive mortars (e.g. lime) and/or bricks. Hence, this study investigates the impact of the interface resistance between brick and mortar, in relation to the properties of the adjacent materials during absorption as well as under real climate conditions. As expected the impact of interface …

A Method For An Effective Microclimate Management In Historical Buildings Combining Monitoring And Dynamic Simulation: The Case Of “Museo Archeologico Di Priverno”, Francesca Frasca, Cristina Cornaro, Anna Maria Siani
International Building Physics Conference 2018
In this work a method is proposed to estimate the effect of indoor microclimate on the risk of degradation of ancient materials stored in historical buildings. The method, which combines microclimate observations and dynamic simulation, has shown to be strategic in preventive conservation of historical buildings. Indeed, once the building model is calibrated, it can be effectively used for evaluating the microclimate control solutions on the conservation reducing general degradation risks. The method has been applied to a historical building close to Rome, where deteriorations in ceilings occurred and visitors complain about thermal discomfort. First, the HVAC system in the …

International Building Physics Conference 2018
In Europe the management costs and lack of flexibility of the sports halls, built in the second half of the ‘900, brought to the progressive abandonment of many structures. In this context the environmental, social and economic sustainable aspects of a refurbishment project of an Italian large sports hall, named “Palasport”, are presented. It was designed by a group of architects and engineers and completed in 1962. It is located in the expo area of Genoa, a north Italian city, called “Fiera del Mare” and it plays a strategic role in the social community. In the past it hosted several …
Characterisation Of The Flexibility Potential From Space Heating In French Residential Buildings, Jérôme Le Dréau, Johann Meulemans
Characterisation Of The Flexibility Potential From Space Heating In French Residential Buildings, Jérôme Le Dréau, Johann Meulemans
International Building Physics Conference 2018
Demand response (DR) at the building level (also named energy flexibility) will play an important role in facilitating energy systems based mostly or entirely on renewable energy sources. Flexibility is thus deemed necessary to control the energy consumption to match the actual energy generation from various renewable energy sources such as solar and wind power. However, there is lack of comprehensive knowledge about how much energy flexibility different building types and their usage may be able to offer to the present or future energy systems. In this study, the flexibility potential of space heating is characterised among the building stock …

International Building Physics Conference 2018
There is growing evidence that heat waves are becoming more frequent under increased greenhouse forcing, associated with higher daytime temperatures and reduced night-time cooling, which might exceed the limits of thermoregulation of the human body and affect dramatically human health. Especially urban areas are affected, since these regions in addition experience an urban heat island (UHI) effect characterized by higher air temperatures compared to the surrounding rural environment. A necessary breakthrough is a shift away from a fragmented approach towards an integrated multiscale urban climate analysis. This type of research is a rather new domain of research and might be …
