Control of HVAC Systems via Scenario-based Explicit MPC

Improving energy efficiency of Heating, Ventilation and Air Conditioning (HVAC) systems is a primary objective for the society. Model Predictive Control (MPC) techniques for HVAC systems have recently received particular attention, since they can naturally ...

A Multi-sensor Office-building Database for Experimental Validation and Advanced Control Algorithm Development

Nicolas Morel, Nikolaos Zarkadis

Data from multiple sensors and actuators has been recorded from December 2001 to March 2008 at the LESO-PB building of the EPFL campus, using the EIB/KNX bus standard. Sensors and actuators provided data on room temperature, presence, lighting level, windo ...

The vertical structure of eddy diffusivity in pure slope flows over smooth surfaces

Jiannong Fang, Marc Parlange, Marco Giovanni Giometto

Thermally driven slope flows are ubiquitous in nature and play a major role in regulating local microclimates in valleys, glaciers and ice-sheets. They control in large part surface momentum, heat and moisture fluxes, and their effects must therefore be ac ...

Release and environmental impact of silver nanoparticles and conventional organic biocides from coated wooden facades

Andrea Ulrich

This study represents for the first time a comprehensive assessment of functionality and environmental impacts of metallic silver nanoparticles (Ag-NP) compared to conventional organic biocides. Four different transparent, hydrophobic coatings of wooden ou ...

Momentum balance of katabatic flow on steep slopes covered with short vegetation

Marc Parlange, Gabriel George Katul, Holly Jayne Oldroyd, Eric Richard Pardyjak

Katabatic flows over alpine mountainous terrain differ from their forested or bare slope counterparts due to the presence of well-ventilated, short vegetation. The impact of a grass canopy and larger-scale pressure perturbations on the one-dimensional mean ...

Consumer Segmentation and Knowledge Extraction from Smart Meter and Survey Data

Karl Aberer, Dipanjan Chakraborty, Tri Kurniawan Wijaya

Many electricity suppliers around the world are deploying smart meters to gather fine-grained spatiotemporal consumption data and to effectively manage the collective demand of their consumer base. In this paper, we introduce a structured framework and a d ...

A Large Eddy Simulation to determine the effect of trees on wind and turbulence over a suburban surface

Marc Parlange, Marco Giovanni Giometto, Andreas Christen

A proper modeling of flow and turbulence within and over urban canopies is key to properly predict air pollution and dispersion in cities. Trees are an integral part of the urban landscape. In many suburban neighborhoods, tree cover is 10 to 30% and trees ...

Implementation of a Scenario-based MPC for HVAC Systems: an Experimental Case Study

Maurizio Molinari, Luca Fabietti

Heating, Ventilation and Air Conditioning (HVAC) systems play a fundamental role in maintaining acceptable thermal comfort and air quality levels. Model Predictive Control (MPC) techniques are known to bring significant energy savings potential. Developing ...

Surface heat flux variability of a large lake: Lake Geneva, Switzerland

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

The heat budget of a lake is a fundamental component of physical limnology, and is strongly dependent on the surface heat flux. However, the surface energy exchange depends on several factors, making it difficult to estimate. In this study we employed seve ...
