Impact of the climate on the design of low-energy buildings for Australia and Reunion Island | 2011 | English
The work presented in this paper aims to compare two different climates in Australia and Reunion Island and to identify the similarities in terms of bioclimatic design of low energy building.
Guidelines for the safe design of semi-open car parks require a minimum amount of open façade in order to ensure an effective removal of heat and smoke during a car fire.
Procedure for performance diagnostic for small air conditioning systems using dynamic simulations | 2011 | English
Because of their low cost, small air conditioning, systems are often installed without any study on building envelope performance and without strictly complying with the rules of art.
In this paper, analysis is performed on the uncer-tainty in energy consumption calculated from whole-building energy models of two different building de-signs; a typical code compliant building, and the same building redesigned with high performan
The aim of thise paper is to take the advantage of CFD application in calculating, optimising, and designing air curtains used to separate smoke free zones in case of fire.
Standardized building performance assessment is best expressed with a so-called normative calculation method, such as the CEN/ISO calculation standards.
The thermal performance evaluation of a future Chinese low energy apartment within changing climate in ‘hot summer and cold winter’ zone in China | 2011 | English
The paper aims to evaluate the thermal performance of a typical Chinese low-energy residential building in ‘Hot Summer and Cold Winter’ zone where two prototypes within a six-storey healthy housing with low-energy standards have been investigated.
Climate based simulation of different shading device systems for comfort and energy demand | 2011 | English
This study investigates in detail conventional and advanced shading devices. Thermal and visual aspects are considered as well as advanced control strategies.
Exploitation of the environmental energy resources: indicators and design strategies | 2011 | English
Assuming that isolating a building might not be the best solution to exploit the free renewable sources of its environment (outside air temperature, sky temperature, solar radiation…), a first identification step has been carried out to determine
Ventilated buildings optimisation by using a coupled thermal airflow simulation program | 2011 | English
This work shows the optimization of natural ventilation within buildings at the stage of design and behaviour of the occupants.
An integrated approach to energy analysis in building design – the relocatable classroom project | 2011 | English
In 2005, the Department of Education and Early Childhood Development (DEECD) in the Victorian State of Australia introduced a new design for relocatable classroom buildings known as the „N1‟ design.
This paper focuses on the study of the office room, investigating the influence of temperature sensor placement on the heating energy consumption and thermal comfort in the central European climate conditions.
Climate change risks from a building owner’s perspective: assessing future climate and energy price scenarios | 2011 | English
Since the last decade, it has seen a surge in the need of uncertainty analysis for building energy assessment, but it is often overlooked that the vital part of uncertainty analysis is the determination of uncertainty in model parameters.
Comparative analysis of natural ventilation performance in non-unifrom double skin facades in temperate climates | 2011 | English
This study compares the performance of three different double skin facade configurations in prevailing summer conditions in a temperate climate.
Thermal insulation of building envelope toward zero energy design in hot-humid climate | 2011 | English
The use of thermal insulation in the building envelope in hot and humid climate is investigated through computer simulation.
Designing the city according to the wind: using a CFD to minimize the impacts of city growth on natural ventilation | 2011 | English
This research studies the influence of changing patterns of land use on natural ventilation using a cfd tool, with a case study in Fortaleza, Ceará, Brazil.
Within the scope of the HOMES programme, five pilot sites (real buildings) were chosen to study the benefits of active energy efficiency on building energy performance.
Thermal comfort in naturally ventilated classrooms: application of coupled simulation models | 2011 | English
This paper presents a novel simulation system which couples a computational fluid dynamics program with a model of human thermal comfort and thermo-regulation.
