The simulation of the energy performance of buildings has historically been compartmentalized along the lines separating different disciplines or different analysis tools, despite their interrelations.
Building energy simulation and object-oriented modelling: review and reflections upon achieved results and further developments | 2009 | English
Over the past 30 years numerous Building Simulation Codes (BSC) have been developed. Nevertheless, none of them has yet become a “standard”.
Methodology for developing reusable scheduler classes applicable for long term building energy simulation | 2009 | English
The aim of this study is to accelerate developments of building simulation programs by using Object- Oriented programming.
Influence of ground heat exchanger modelling on the predicted efficiency of the heat pump system | 2009 | English
This paper presents simulations of the integral coefficients of performance of a heat pump system coupled with a vertical ground heat exchanger (GHE).
Use of response factor method to model earth-to-air heat exchanger behaviour. Integration in a whole building simulation into SIMSPARK plat form | 2009 | English
This paper shows the numerical model of an earth-toair heat exchanger. The system is discretized into “n” sections perpendicular to the exchanger pipe.
Simulation of a domestic ground source heat pump system using a transient numerical borehole heat exchanger model | 2009 | English
Common approaches to the simulation of Borehole Heat Exchangers (BHEs) assume heat transfer in circulating fluid and grout to be in a quasi-steady state and ignore fluctuations in fluid temperature due to transport of the fluid around the loop.
Seasonal storage of solar energy in geothermal boreholes has resurfaced as a means of heating housing communities.
The transfer of energy from the ground to buildings through slabs and basements has long been a point of large errors in simulations. Work to increase the accuracy of this ground-coupled heat transfer was started under IEA Task 34/43.
Comparison of standard and case-based user profiles in building’s energy performance simulation | 2009 | English
The user’s action is a decisive factor in the energy performance of a building. In this paper is demonstrated the necessity of using more specific user’s profiles (UPs) in simulations of building’s energy performance (EP).
Methodology to enhance the Portuguese thermal regulation accuracy for existing buildings | 2009 | English
The goal of this study is to evaluate the accuracy of the Portuguese thermal regulation simplified methodology for existing buildings and to assess the influence of different parameters on the building final energy performance evaluation. Simple “
Asset rating: disagreement between the results obtained from software for energy certification | 2009 | English
The general practice for establishing the consumption in asset ratings of a building consists of entrusting the energy analysis of the shell of a building to calculating software. The building is the subject of an extremely complicated analysis, a
An analysis of results variability in energy performance compliance verification tools | 2009 | English
To address the functional complexities and volumetric variability found in the UK non-domestic building stock (Pérez-Lombard et al, 2008, Bruhns, 2008), the methodology for demonstrating compliance with energy performance criteria outlined in Appr
As part of the UK government Energy Performance of Buildings Directive (EPBD) initiative, the requirement of Asset and Operational Ratings for buildings since 2008 meant that software packages have recently been made available commercially to carr
Based on almost seven years of continuous measurements we have analysed in detail the influence of occupancy patterns, indoor temperature and outdoor climate parameters (temperature, wind speed and direction, relative humidity and rainfall) on win
This paper presents the results of a recent study of people's presence and their interactions with the buildings' environmental systems in a number of buildings in Austria.
Based on six years of continuous measurements, we have analysed in detail the occupancy, thermal and visual parameters influencing blind usage behaviour. This paper begins by presenting some of the key findings from these analyses.
Total utility demand prediction based on probabilistically generated behavioral schedules of actural inhabitants | 2009 | English
This paper describes a new methodology in calculating accurately the time series utility loads (energy, power, city water, hot water, etc.) in a dwelling.
On selecting weather data sets to estimate a building design’s robustness to climate variations | 2009 | English
The integration of techniques for uncertainty and sensitivity analysis in building performance simulation (BPS) has a number of potential benefits related to design.
Climate Modelling is a complex task. One of the most important reasons is the presence of a large variety of spatio-temporal scales.
