Reinforcement learning for HVAC control in intelligent buildings: A technical and conceptual review
Heating, Ventilation and Air Conditioning (HVAC) systems in buildings are a major source of global operational CO2 emissions, primarily due to their high energy demands. Traditional controllers have shown effectiveness in managing building energy use. However, they either struggle to handle complex environments or cannot incorporate learning from experience into their decision-making processes, leading to […]

From social manufacturing and entrepreneurship to social open innovation: Exploring the role of fabrication laboratories
The research aims to shed light on the role of open innovation in addressing social and economic challenges. It focuses on 3D-based fabrication laboratories (fablabs) and attempts to identify the mechanisms through which the latter facilitates the diffusion and promotion of (open) innovations. The findings reveal how fablabs and additive manufacturing (AM) enable the scaling […]

LEAN-BIM SYNERGY IN THE CONSTRUCTION DESIGN PHASE: AUTO-GENERATION AND EVALUATION OF THERMAL ALTERNATIVES
This study explores the integration of Lean principles with Building Information Modeling (BIM) to enhance decision-making in the relatively unexplored field of thermal design for construction projects. Recognizing the limitations of current design processes, characterized by insufficient alternatives and a lack of team collaboration, we introduce a new decision-making tool. This tool centers on a […]

Sampled-Data Observer Design for Linear Kuramoto-Sivashinsky Systems with Non-Local Output
The aim of this paper is to provide a novel systematic methodology for the design of sampled-data observers for Linear Kuramoto-Sivashinsky systems (LK-S) with non-local outputs. More precisely, we extend the systematic sampled-data observer design approach which is based on the use of an Inter-Sample output predictor to the class of LK-S systems. By using […]

Impact of polypropylene fibers on the rheological, mechanical, andthermal properties of self-compacting concrete
The objective of this experimental investigation is to examine the impact of using polypropylene fibers on the properties of self-compacting concrete (SCC). Five mixtures were prepared, one reference concrete (without fibers) and four other SCC containing, 0.05,0.1, 0.15, and 0.2% of polypropylenes fibers. Rheological (slump flow, yield stress, and plastic viscosity) and mechanical (compressivestrength) properties […]

Meeting the challenges of effective readiness for change in a global context
The aim of this paper is to address the potential impact of perceptions on individual readiness for change. Based on a quantitative survey of 310 executives from Anglo Saxon countries, North and Latin Europe, Arabian countries, and Far East Asian countries, identified via multi stage sampling, we compare the impact of employees’ cultural factors (cultural […]

Enhanced multi-horizon occupancy prediction in smart buildings using cascaded Bi-LSTM models with integrated features
Accurate occupancy prediction in smart buildings is crucial for optimizing energy management, improving occupant comfort, and effectively controlling building systems, particularly for short- and long-term horizons. Recently, deep learning-based occupancy prediction methods have gained considerable attention. However, the full potential of these methods remains under explored in terms of model architecture variations and prediction horizons. […]

Unlocking the sources of individual readiness for change: exploring the role of nationality
This paper aims to examine primarily the readiness for change at an individual level. Additionally, this study examines the impact of internal change factors on individual readiness for change as well as their effect across nations.

Fondements théoriques de l’effet Proteus : comment les avatars influencent le comportement des utilisateurs
L’effet Proteus est un phénomène, décrit pour la première fois en 2007, qui illustre la façon dont l’incarnation d’avatars en réalité virtuelle peut moduler l’attitude et le comportement de son utilisateur. Malgré les nombreuses démonstrations de l’effet dans la littérature, attestant de sa validité, notre compréhension des mécanismes cognitifs à l’origine du phénomène reste insuffisante. […]

Characterizing the Culture of Teal Organizations
Teal organizations arose around the world in the last decades and were recently described as potentially announcing a new stage of evolution for human organizations. They are characterized by three defining features: Self-management, Wholeness, and Evolutionary purpose. As the emergence of such organizations echoes other signs of change in the workplace and in society, we […]

Optimizing Comfort and Energy Efficiency: The Impact of Model Accuracy on Multi-Objective MPC
Abstract—Buildings are responsible for ∼30% of primary energy consumption, mainly because of Heating, Ventilation, and Air Conditioning (HVAC) systems. The usual ON/OFF controller tends to react to occupancy presence, causing discomfort and energy waste. Furthermore, these controllers usually focus on thermal comfort and disregard other comforts, such as air quality, visual, etc. due to their […]
