This paper presents a new methodology of machine aided HVAC system optimization with currently available building simulation and optimization frameworks.
Torsten Schwan, René Unger, Christian Lerche, Bernard Bäker
The paper focuses on control optimization of nonlinear system models where the differential-algebraic equations are formulated in Modelica.
Dominik Wystrcil, Doreen Kalz
In previous studies, the authors combined load shifting and Model-based Predictive Control (MPC) for the optimization of a HVAC system.
Renato Lepore, Eric Dumont, Christine Renotte, Marc Frere
This research aims to define a modelling approach to simulate District Cooling Systems (DCS). A model of the network has been developed using the equation-based object-oriented language Modelica.
Damien Casetta, Cynthia Nerbollier, Guillaume Brecq, Pascal Stabat, Dominique Marchio
A simulation model is developed that allows to investigate the infection risk for Legionella Pneumophila in the design phase of a DHW system and to test the effectiveness of disinfection techniques on an infected system.
Jelle Laverge, Elisa Van Kenhove, Peter De Vlieger
The major goal of this study is to demonstrate the feasibility of the dynamic modeling and simulation of both conventional and direct exchange geothermal heat pump applications particularly with regard to performance evaluations.
Roozbeh Sangi, Pooyan Jahangiri, Freerk Klasing, Rita Streblow, Dirk Müller
This paper presents a new approach to calibrate air handling unit models. This approach studies every heat exchanger component separately based on the inverse problem framework, the Preisach model of hysteresis and machine learning techniques.
Jesús Febres, Raymond Sterling, Marcus Keane
In this paper, four different data-driven algorithms including AutoRegressive with eXternal inputs (ARX), State Space (SS), Subspace state space (N4S) and Bayesian Network (BN) are evaluated and compared using a case study of predictions of Air Ha

This paper presents a methodology of simultaneous sizing of building envelope and heating system integrating management strategies in sketch phase.
Dinh Van Binh, Delinchant Benoit, Wurtz Frédéric
Ceiling fans recirculate air within a space and affects the comfort of the occupant. It is widely used in India. It reduces the perceived temperatures by assisting cooling by evaporation through skin.
Nishesh Jain, Gaurav Shorey
Attic spaces belong among the most popular forms of housing or working.
Kristian Kondas, Martin Kamensky, Martin Lopusniak
The scientific literature offers a number of methods for assessing the likelihood of overheating in buildings.
Theofanis Psomas, Per Heiselberg, Karsten Duer, Eirik Bjørn
In the absence of thermal comfort standards in India, architects and designers have no choice, except to provide air conditioning to meet thermal comfort criteria for achieving green building rating for their projects and thus end up using more en

This paper evaluates the influence of underground piping on the performance of using increased thermal capacitance (ITC) as a passive energy management system on an office building.
Joseph Paul Carpenter
The paper presents an application of a new method to simplify models of heat sources in CFD simulations of large spaces exposed to variable occupancy patterns.
Petr Zelensky, Martin Bartak, Jan L.M. Hensen
Appropriate building design for natural ventilation can reduce discomfort, while saving energy on airconditioning.
Jay Dhariwal, Rangan Banerjee
Simulations were conducted to optimize the design of a small building with walls constructed of limestonefilled gabion baskets.
Lydia Kairl, Veronica Soebarto
This paper presents an analysis of internal air temperatures measured hourly in the living rooms of 10 domestic buildings in the city of Leicester, UK.
Argyris Oraiopoulos, Tom Kane, Steven K Firth, Kevin J Lomas
The paper presents a numerical methodology to assess wind pedestrian comfort and natural ventilation in urban areas. UrbaWind, an automatic computational fluid dynamics code, is improved to model the wind in dense urban environments.
Stephane Sanquer, Guillaume Caniot, Sachin Bhandare
Building performance simulation has been utilised for the investigation of thermal comfort and airflow within a naturally ventilated, self-sufficient house in a bushfire prone area.
Yanni Papadopoulos, Veronica Soebarto
