This paper deals specifically with analysis of the thermal, airflow and daylighting performance of the façade elements and in particular with the Double Skin Façade (DSF) applied to the south and southeast facing office spine of a laboratory build
In this paper, microscopic and macroscopic flow analyses have been employed to identify and analyze the causes of discrepancies of power law zonal models.
This paper investigates airflow in an office room with a displacement ventilation system parametrically using three-dimensional CFD.
The present paper investigates, both experimentally and by simulation, the influence of faulty VAV units that do not affect the zone temperature on total energy consumption of a VAV system.
Influence of component selecting size method of hydronic networks on global costs and comfort | 2005 | English
Modelling and assessment of ground-source heat pump systemsusing exergoeconomic analysis for building applications | 2005 | English
Ground source heat pumps (GSHPs) are modelled, analyzed based on exergy, cost, energy and mass, and evaluated exergoeconomically.
From computer models to simple design tools:solar rights in the design of urban streets | 2005 | English
This work presents a simple design tool for the consideration of solar rights in urban design that was developed by the use of the computer model SustArc (Capeluto and Shaviv, 1997).
Communications between buildings and their occupants through multimodal Human Computer Interactions (HCI) can dramatically enhance the way buildings are experienced.
Whereas water can frequently come in contact with wood-based building envelope components, little work has tried to measure and model moisture uptake in orthotropic wood.
Energy efficiency and thermal comfort analysis using the powerdomus hygrothermal simulation tool | 2005 | English
The building simulation tool Domus has been recently renamed as PowerDomus for whole-building hygrothermal and energy simulation.
Building performance simulation tools have significantly improved in quality and depth of analysis capability over the past thirty-five years.
Modeling of the double-skin facades for building energysimulations: radiative and convective heat transfer | 2005 | English
A comprehensive modeling of radiative and convective heat transfer of a compact double-skin facade equipped with venetian blind is proposed here.
Exergoeconomic modeling of geothermal district heating systems for building applications | 2005 | English
Geothermal district heating systems (GDHSs) are modeled by examining the relations between thermodynamic losses and capital costs for the devices comprising the GDHSs, and some possible generalizations are proposed relating thermodynamic losses an
Stand-alone software for predicting contaminant transport and behaviour is well developed, but to be more effective, it needs to be integrated within whole building simulation.
This paper deals with the development and the evaluation of hybrid ventilation control strategies, using both natural and mechanical modes, in residential buildings using a graphical simulation tool. The description of a library of airflow compone
Impact of the atmospheric boundary layer profile on the ventilation of a cubic building with two large oppositeopenings | 2005 | English
The aim of this paper is to show the influence of the atmospheric boundary layer profile on the distribution of velocity in a building having two large openings.
The paper describes a research project which addresses the problem of supervisory control of systems which include a range of heat sources combined with active and passive thermal storage. The work is based around a prototype building which has a
This paper describes how the energy performance of single storey multiple-skin facades can be optimized by changing the settings of the facades and HVAC system. The energy performance is analyzed with a yearly whole building energy analysis under
Evaluation of energy saving investments in buildings as a system of interdependent projects | 2005 | English
During a design stage building designers have to do many decisions that will influence an energy consumption in a designed building. Investments to a building structure and HVAC system are a basis for a low consumption of an energy.
