Conference Paper
Full-text available
The ability to predict the thermal performance of building envelope components in a given context and climatic setting constitutes a big advantage in the planning phase, when designing a building to be both energy-efficient and cost-effective. In the framework of a CTI project we developed a dynamic simulation model for translucent PCM modules. The...

A significant amount of energy is wasted every year by heating unoccupied indoor spaces in residential buildings. How much energy can be saved by reducing the heating during the hours with no occupancy? Simulation results of a multi-family residential building typical for the Swiss housing stock show that, when the setpoint temperature is equally r...

Full-text available
Within the scope of the present study, reference values for embodied energy, greenhouse gas emissions and total environmental impact of heating, ventilation, sanitary and electrical systems were compiled. The focus was put on building services systems that are common and widespread in residential, administrative and school buildings. The main objec...
Chapter
Die globale Erwärmung bringt zunehmend auch in der Schweiz neue Herausforderungen bei der Planung von Wohnsiedlungen und Quartieren. Die Berücksichtigung von klimatischen Trends und insbesondere die Vermeidung von Hitzeinseln wird bei der klimaangepassten Siedlungsentwicklung zunehmend wichtig. Planer und Baubeteiligte im Allgemeinen verfügen aber...

Kann mittels Steuerung der Transmissionsverluste durch die Gebäudehülle Kühlenergie eingespart werden? Diese Frage lässt sich mittels thermisch-energetischer Simulation beantworten. Erkenntnisse aus einer Potenzialstudie.

According to current estimations, approximately 1.5 million buildings in Switzerland are in need of renovation. On the other hand, more than 400,000 homes change tenant every year, with a stagnating renovation rate of about 1 percent. The potential that exists in most apartment changes is often not realized with extensive renovations. In the presen...
Technical Report
Energieeffizientes Bauen erfordert nebst einer thermisch hochgedämmten Gebäudehülle auch eine hohe Luftdichtigkeit und kontrollierte Luftwechselraten. Bei typischen energetischen Sanierungen werden üblicherweise oberirdische Bauteile verändert. Bauteile gegen das Erdreich werden hingegen eher selten nachgedämmt. Falls solche Bauteile Infiltrationss...

Die Begrünung von Quartieren und Gebäuden wirkt Hitzeinseln entgegen. Noch gibt es erst wenige wissenschaftliche Erfahrungswerte. In einem Forschungsprojekt erarbeitet die Hochschule Luzern die Grundlagen.

Conference Paper
Full-text available
Translucent phase change materials (PCM) are used as filling in commercially available latent heat storage modules, which can be readily integrated into the building envelope in place of a normal window. This paper presents a model for the dynamic simulation of the thermal performance of translucent phase change materials as well as its application...
Article
Full-text available
Energetische Sanierungen bewirken in der Regel, je nach baulichem Eingriff, eine Erhöhung der Luftdichtigkeit der Gebäudehülle. Ob und unter welchen Bedingungen dies auch zu einer höheren Radonkonzentration im Gebäude führen kann, wird im Rahmen einer Studie der Hochschule Luzern untersucht.
Conference Paper
Full-text available
Well insulated building envelopes have the drawback that – when the outdoor temperature drops below the indoor temperature – they hinder passive heat losses in buildings with high internal gains and cooling demand. This results in an increase of the cooling energy consumption. The present study investigates the energy saving potential of a building...
Conference Paper
Full-text available
A mathematical model is presented describing the thermal behavior for a translucent facade element, which uses phase change materials to increase building energy efficiency. The model puts the focus on accurately representing sub-cooling effects in the salt hydrate (phase change material) which is used. Based on this model a library module for the...
Conference Paper
Full-text available
The paper places the extensive body of knowledge on adaptive building components in the context of providing and maintaining a lasting performance robustness for integrated building systems. It furthermore differentiates three stochastic variables which potentially endanger a robust building performance: climate change, occupant's behavior and HVAC...

Im Rahmen eines durch den Kanton Luzern und das Bundesamt für Gesundheit (BAG) finanzierten Projektes wurden von der Hochschule Luzern – Technik & Architektur, in Zusammenarbeit mit der inNET Monitoring AG, Messungen der Radonbelastung in Gebäuden mit Luft-Erdwärmetauschern durchgeführt.
Thesis
Modern high-rise buildings must not only contribute to the reduction of land use, but do also have to be designed to comply with the principles of sustainability. The aim of this work is to develop a set of criteria and a methodology for the assessment of the sustainability of high-rise building’s facades. On the basis of existing tools for assessi...
Thesis
Full-text available
Indoor climate is a key factor determining the development of damage inside historical buildings. Processes like salt weathering are largely controlled by the temperature and the relative humidity of the environment. In the present work hygrothermal simulations of the indoor climate of a church were performed with a novel hygric model used in combi...

RUNSALT is a graphical user interface to the ECOS thermodynamic model described in Price, C. A. (Ed.), 2000: "An expert chemical model for determining the environmental conditions needed to prevent salt damage in porous materials". European Commission Research Report No 11, (Protection and Conservation of European Cultural Heritage). Archetype Pu...

In order to limit the damage caused by microclimatic impact on sensitive monuments, it is necessary to optimize the methods of preventive conservation and improve the understanding of the complex interactions involved. A case study is presented where magnesium and sodium sulfate salts are significant contributors to the deterioration on the walls i...

The response to changing environmental conditions (relative humidity and temperature) of the salts in the test room of the Tenaille von Fersen building, Suomenlinna, Finland, was simulated using the thermodynamic model of ECOS (Price 2000) and the computer program RUNSALT (Bionda 2002). The results show that for any ionic combination tested, the ra...
Technical Report
Full-text available
In this study the carbonate diagenesis of Holocene lacustrine sediments of the Danube-Tisza interfluve, Central Hungary, was investigated. The lacustrine sediments are precipitated in shallow lakes and ponds and contain calcite, low- and high-Mg calcite, Ca-dolomite and dolomite. The underlying aeolian sediments also contain a range of carbonate mi...
Conference Paper
In origin of life studies, the search for the oldest microfossil evidence is challenging because of the high degree of post-depositional alteration of Early Archean sedimentary rocks that has occurred over the aeons. We present here a study of a partially unaltered Dolomite Unit, located in the Coongan Belt of the eastern Pilbara Craton granite-gre...

The Upper Ladinian Kalkschieferzone (KSZ) is a 125 m thick sequence of finely laminated bituminous limestones, marls and massive limestones. The laminated limestones have an organic carbon content reaching up to 6% and are thought to have been deposited in a shallow basin or lagoon with anoxic bottom waters. The lamination may reflect a seasonally...
