چکیده
Abstract In the last years, new technical standards for assessment of energy efficiency building systems were developed by European Committee Standardization (CEN). These procedures conceived as to combine easiness calculation methodologies and their related assumptions with a sufficient level accuracy. While former objective is often achieved, latter challenging task sometimes fail simulate in proper way actual performance systems. On other hand, detailed applied dynamic simulation tools are more precise complex; however, application, they need wide range input data that hard collect. For this reason, simplified now commonly applied, above all case existing buildings. Nevertheless, these be deeply analysed validated. paper, main standard addressed chillers specified EN 16798-13:2017 analysed, focus on required procedures. The same approach was then methods used EnergyPlus TRNSYS, results compared. theoretical analysis followed study approach. A reference office building, representative Italian stock, selected two different climatic zones. determination thermal cooling performed means EnergyPlus, while demand both This paper part wider research activity finalised procedures, taking into account generation coupling modes between itself.

متن کاملAutomating Dynamic Decoupling in Object-Oriented Modelling and Simulation Tools
This manuscript presents a technique that allows Equationbased Object-Oriented Modelling Tools (EOOMT) to exploit Dynamic Decoupling (DD) for partitioning a complex model into “weakly coupled” submodels. This enhances simulation efficiency, and is naturally keen to parallel integration or co-simulation. After giving an overview of the problem and of related work, we propose a method to automate...

In this paper some new methods whitch very recently have been introduced for parameter estimation and variable selection in regression models are reviewd. Furthermore , we simulate several models in order to evaluate the performance of these methods under diffrent situation. At last we compare the performance of these methods with that of the regular traditional variable selection methods such ...
