The development of an innovative radiant heating system, made for room temperature control, requires extended laboratory and numerical analysis. The multilayered wooden structure design in particular is a challenging aspect due to thermal and hygric transport processes. This article focuses on a thermal optimization process, which aims at increasin...
This paper utilizes computational fluid dynamics and heat, air, and moisture modeling to enhance the quality of results for the case study of forced convection through an air cavity. Different turbulence models and near-wall modeling techniques were combined and a mesh sensitivity study was conducted to ensure numerical correctness. The results are...
The characterization of the dynamic behavior of building opaque elements is essential to compare different design and refurbishment alternatives. Indeed, the building envelope’s dynamic response to external weather conditions can play a key role in the building energy performance. This is true especially for cooling dominated climates but also for...
![Properties of the measurement instrument. [12][13]](publication/356733286/figure/tbl1/AS:1098387642425346@1638887429196/Properties-of-the-measurement-instrument-1213_Q320.jpg)
This study presents in situ monitoring data of three different glazing systems over a period of one year. An insulated glass unit (IGU), a Vacuum Insulated Glass hybrid unit (VIG-hybrid) and an opaque architectural insulation module (AIM) were monitored under the equivalent environmental condition in this study. Different issues were observed and a...
In the ongoing discourse on the recyclability and sustainability of building materials, this study explores the potential of paper-based materials for use in construction, with a particular focus on their hygrothermal performance. Current research suggests that paper, with its well-established recycling cycles, is a promising and cost-effective alt...
The contribution highlights the potential of paper-based materials in creating circular, sustainable exterior wall systems.
Reducing energy consumption and using renewable energy sources for the building operation is crucial to achieve lower overall greenhouse gas (GHG) emissions. In this case study we conduct a building energy system optimisation for a new residential district in Darmstadt, Germany under different boundary conditions using the optimisation software Sym...
Ground source heat pumps (GSHP) coupled to shallow borehole heat exchangers (BHE) represent a low emission technology to provide space heating and cooling. However, ongoing long-term heating or cooling of the ground caused by unbalanced loads leads to a performance decline and in the worst case to a system shutdown. Enhanced regeneration can increa...
To contribute to carbon neutrality, energy efficiency measures in existing factories must be evaluated holistically, considering not only production and technical building equipment but also the building itself. In this study, a package is introduced as part of a simulation library which aims to identify integrated energy efficiency measures. The p...
The presence of liquid water on the facade surface significantly contributes to the growth of microorganisms. This issue has become increasingly important with the growing use of thermal insulation in buildings. However, the formation of condensation on these façades is often increased due to low surface temperatures. Therefore, innovative coating...
Im Reallabor DELTA werden energiesystemische Methoden angewendet und energietechnische Anlagen errichtet, um erfolgreiche Pilotprojekte der urbanen Energiewende in die breite Anwendung zu überführen. Im Mittelpunkt steht die konsequente Steigerung der Energieeffizienz in allen Sektoren, die bereits heute als größtes nutzbares Potenzial der urbanen...
In the living lab DELTA, energy system methods are applied, and energy technology systems are installed to transfer successful pilot projects of the urban energy transition to a broad application. The focus is on the consistent improvement of energy efficiency in all sectors, which is already considered to be the largest usable potential of the urb...
As renewables become more established in the electricity grid, the focus, and therefore adaptability, will need to shift from the generation side to the demand side. Since the building sector accounts for a large share of the energy demand, it will be strongly affected by this development. One possibility for adaptation is so-called demand side man...
In this study, a method is proposed to expand the utilization of an existing calculation model for a floor heat exchanger (HX) from room scale to small district scale. The model, namely Trnsys Type 653, is typically employed for the simulation of single or simultaneously controlled parallel heating circuits. It uses a simplified approach to calcula...
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 par...
This paper utilizes computational fluid dynamics and heat, air, and moisture modeling to enhance the quality of results for the case
study of forced convection through an air cavity. Different turbulence models and near-wall modeling techniques were combined
and a mesh sensitivity study was conducted to ensure numerical correctness. The results are...
The characterization of opaque building components’ thermal behavior is essential in early design stages to compare different design and refurbishment alternatives. Evaluating the dynamic thermal response to an external solicitation is necessary for an effective design especially for the climates with important annual cooling demand. According to E...
Multilayer solid wood panels are used in civil engineering as construction element as well as design- and functional element. The funda-mental idea of this industry driven project was the integration of climatic-control functions (cooling/heating) with fluid filled elements in multilayer solid wood panels. Solid wood panels with different design we...
Numerical analysis of anisotropic building components requires sophisticated transient simulation models. Especially in case of
wooden components, anisotropic properties are additionally taken into account, in order to obtain reliable results. Within an
industry driven project a solid wood panel with an integrated functional pipe element is to be d...
Wood industry's current economic development shows an increase of selling multilayered solid wood panel products accompanied by a crescent functionalization of those panels. Within an industry driven project an additional functionalization in form of pipe elements for heating and cooling are to be applied to a multilayered solid wood construction....
The use of multilayer solid wood panels has become increasingly popular in the construction sector in the recent years. The ecological and sustainable production of wood is leading to this demand. The development of a three layer solid wood panel with a functional pipe element in the middle layer is been investigated in the frame of an industry dri...
