Thermal Performance Of Pcm-Glazing Unit Under Moderate Climatic Conditions, Anna Wieprzkowicz, Dariusz Heim
International Building Physics Conference 2018
Considering physical properties, transparent or translucent building components like windows or glazing facades are the weakest elements of building envelope. The heat transfer coefficient of such elements is approximately four times higher than for opaque partitions, which causes considerable increase of heat loss during winter. In summer relatively high solar transmittance is a source of heat gains which results in undesirable overheating. Application of phase change materials in glazing components affects its thermal performance by the increase of its heat capacity and decrease of solar heat gains, with regard to the current physical state of the PCM. The aim of …

Experimental Study On The Impact Of Passive Chilled Beam In A Room With Displacement Ventilation, Zhu Shi, Vishal Anand, Qingyan Chen
Experimental Study On The Impact Of Passive Chilled Beam In A Room With Displacement Ventilation, Zhu Shi, Vishal Anand, Qingyan Chen
International Building Physics Conference 2018
Previous studies have demonstrated that displacement ventilation (DV) can provide better air quality than mixing ventilation (MV), and may save energy in buildings. However, since DV introduces supply air to the occupied zone directly, the temperature of supply air it provides is normally higher than in a MV system, so the ability to remove cooling load is limited with the same amount of air. On the other hand, passive chilled beam (PCB) systems have been shown to be able to remove a large cooling load while saving energy. Therefore, this research studied a coupled configuration that combined DV and PCB, …

Simulation-Based Approach To Optimize Courtyard Form Concerning Climatic Comfort In Hot And Humid Climate, Mehmet Bekar, Gülten Manioğlu
International Building Physics Conference 2018
In hot and humid regions, in order to provide indoor thermal comfort conditions, most important design strategies are to maximize shady areas and natural ventilation. Courtyard building form was developed mainly in response to climatic requirements especially in hot climates. A courtyard is an unroofed area that is completely or partially enclosed by walls or building spaces. The function of the courtyard is to improve comfort conditions by modifying the microclimate around the building. The proportion of the courtyard affects considerably the shadows produced on the building envelope, and consequently the received solar radiation and the comfort conditions in the …

A Dynamic Thermal Network Model Applied To Ventilated Attics, Johan Claesson, Petter Wallentén
International Building Physics Conference 2018
The need for tools to analyze heat and moisture behavior in wooden constructions is increasing with the increasing awareness of the moisture problems. An example of a construction with a history of mould problems is cold attics. Most heat models of attics use a lumped node technique for energy balance and ignore the variation in heat transfer coefficients. A model based on so called dynamic thermal networks has been developed that takes into account radiation between the interior surfaces and the different boundary conditions at the outside and inside surfaces. The first step is to develop analytical solutions for the …

Considerations On The Thermal Modelling Of Insulated Metal Panel Systems, Ligia Moga, Ioan Moga
International Building Physics Conference 2018
The very strict regulations imposed by the European directives regarding low energy consumptions of buildings imposes the availability of thermal and energy efficient solutions for the building envelope. One common solution is given by insulated metal penal systems, which are typically used for industrial buildings but lately also used for other types of buildings (e.g. residential buildings, hotels, hospitals). These types of solutions must be properly addressed from the thermal modelling and simulation point of view considering a different thermal behaviour due to its detail components. For insulated metal penal systems the typical calculations are done by considering only the …

International Building Physics Conference 2018
The target of the nearly zero-energy building (nZEB), stated by the European Union, represents one of the most strenuous challenges to reduce energy consumptions and greenhouse gas emissions in the building sector. In Italy, the nZEB concept refers to a set of energy performance requirements, fixed at national level and establishing a maximum allowable mean thermal transmittance value of the building envelope, as a function of the heating degree-days and of the shape factor. The building envelope is becoming more and more thermally insulated; this determines the reduction of the energy need for heating, but on the other hand it …

The Effect Of Ambient Moisture Conditions On Heat Flux Time Shift And Decrement Factor Of Multi-Layered Walls, Nadja Bishara, Andrea Gasparella
International Building Physics Conference 2018
Thermal properties of the opaque building envelope components are crucial for limiting the energy needs of a building. In particular, dynamic thermal properties of envelope components can significantly contribute to the minimization of heat transfer through the envelope and to the appropriate utilization of the internal and solar gains. This is particularly important in the cooling operation, especially in hot climates. Previous experimental and numerical studies on the determination of dynamic thermal parameters of opaque building components neglected the influence of moisture conditions prevailing within the ambient climate. This paper utilizes a calibrated and validated dynamic heat and mass transfer …

Conceptual Framework For Improved Management Of Risks And Uncertainties Associated With The Performance Of The Building Enclosure, Ivar Björnsson, Miklós Molnár
International Building Physics Conference 2018
The building enclosure has a substantial impact on the overall performance of a building, especially in relation to moisture safety, energy use, environmental footprint and economy. Although the introduction of novel building technology can increase the risk of failures in terms of reduced building performance, failures can also result from the recurrence of past mistakes while using well established building technologies. This indicates that the dissemination of existing knowledge, often documented in project reports, handbooks or experience databases, is not always carried out in an efficient way. One way of addressing the issue is by increasing awareness concerning potential risks …

Evaluation Of Efficiency And Renewable Energy Measures Considering The Future Energy Mix, Fabian Ochs, Georgios Dermentzis
International Building Physics Conference 2018
Sustainable and responsible use of resources is required in order to mitigate climate change. Micro-economic goals usually consider the capitalized investment costs and/or the purchased energy but disregard environmental impacts. However, on macro-economic scale, the aim must be the reduction of the (non-renewable) primary energy (PE) use and of CO2-emissions. There is need for an appropriate evaluation method for comparing and ranking different passive and active building technologies, e.g. according to their impact on the PE consumption. National conversion factors for PE/CO2 differ significantly between different countries and are subject to change. Seasonal variations are not considered at all. The …

Developing And Testing Visual Privacy Metrics, Noor Alkhalili, Ted Kesik, William O'Brien, Terri Peters
International Building Physics Conference 2018
The dense redevelopment of inner cities (intensification) has been accompanied by a dramatic surge in the development of multi-unit residential buildings (MURBs) within ever shrinking proximities to one another. Modern multi-unit residential building design often embodies conflicting desires for daylighting and visual privacy, or designers simply do not consider collective occupant discomfort factors. Thus, the focus of this project was to develop and validate conceptual and quantitative variables influencing visual privacy, such that future and existing residential designs can be analyzed from a visual privacy perspective. This paper formulates an approach that combines building physics (visual angles and relative brightness) …
