Integrated building design, information and simulation modelling: the need for a new hierarchy | 2011 | English
Design of refurbishment: determining of parameters to be measured to adjust the predicted energy calculation | 2011 | English
The purpose of the CEBO research project is to propose a tool to assess the Effective Consumption of Occupied Buildings by calculation, which will be adjusted by measurement parameters that are limited in number and monitoring time. In this paper
Coupling strategy of HVAC system simulation and CFD Part 2: Study on mixing energy loss in an air-conditioned room | 2011 | English
A coupled analysis of heating, ventilation and air-conditioning (HVAC) system simulation tool and computational fluid dynamics (CFD) model was carried out to assess the mixing energy loss in an air-conditioned room where heating and cooling oper
This paper reports how the coefficient of performance (COP) of air-cooled chillers can be improved by adopting variable condensing setpoint temperature control and using mist evaporation to pre-cool ambient air entering the condensers to trigger a
The main objective of this paper is to analyse the thermal comfort of users of a naturally ventilated building, located in the city of Florianópolis, Brazil. The analysis was performed by using the EnergyPlus computer programme.
Coupling strategy of HVAC system 1 simulation and CFD part 1: study on the design phase of an under floor air distribution system | 2011 | English
This report describes the utility of coupling an energy simulation tool and computational fluid dynamics (CFD) for modelling a heating, ventilation and air-conditioning (HVAC) system, and demonstrates the application of this method in the design p
To predict the mould growth risk during the design stage, a mould prediction model can be used. Several models are found in literature (e.g.
Operation strategies for an office building integrated with multi-story double skin facades in the heating season | 2011 | English
In this paper, heating energy saving strategies for winter are proposed for office buildings with a multi-story double skin façade.
The aim of the present work is to improve night venti-lation control strategies, specially for the mid-season periods where an unadapted control scheme can re-sult in undesirable heat loads.
Providing thermal interior comfort in buildings in temperate climate zones is an energy-demanding task that can be optimized through refurbishment.
Optimizing building designs using a robustness indicator with respect to user behavior | 2011 | English
Multi-objective optimization algorithms are used in the building design process to find optimal solutions for design problems. Typically, these algorithms provide the decision maker with a Pareto front containing trade-off solutions.
Research experts participating in the International Energy Agency (IEA) Task 40 project on Net Zero Energy Buildings (Net ZEB) were asked to classify their countries climate.
This paper presents a case study of the role that Computational Fluid Dynamics (CFD) played in the design of modifications to the existing Hamer Hall auditorium Heating Ventilation and Air-Conditioning (HVAC) systems. The use of CFD allowed the de
The Test Reference Year (TRY) weather file was developed in 1993; in 2009 the Typical Meteorological Year (TMY) became the new standard weather file to use in energy based simulations.
Modeling of heat transfer in geothermal heat exchanger using GHZ zonal model method | 2011 | English
Two types of Ground Heat Exchanger (GHX) zonal models are suggested for a new analysis method that can reduce analysis time and reflecting heat transfer mechanisms occurring on the GHX section; using a circular pattern (Circular) and replacing the
Blinds down under – a comparative analysis of shading systems for sustainable building refurbishments | 2011 | English
This research investigates glare control strategies in reference to operational energy consumption and productivity for sustainable upgrades of existing buildings in two very different climate zones.
Trombe wall thermal performance for a modular façade system in different Portuguese climates: Lisbon, Porto, Lajes and Funchal | 2011 | English
Trombe wall and high performance glazing are the façade system improvements used in this research.
Multi-objective optimisation of the configuration and control of a double-skin facade | 2011 | English
We present a new approach to the optimisation of Double-Skin Facades (DSFs). Parameters defined possible geometries, shading devices, openings and ventilation paths, as well as control schedules for their operation.
Using energy simulation and real-time data monitoring to investigate thermal performance of exterior cavity walls | 2011 | English
Integrated cavity-wall systems are typically designed to shade the exterior of buildings. They can also eradicate daytime heat absorption by thermal convection.
The Israeli standard 5282 for energy rating of buildings includes, besides a Prescriptive path, a Performance Approach that requires using an hourly energy simulation model to demonstrate compliance.
