Ground characterization of building energy models

Autotune E+ Building Energy Models

This paper introduces a novel “Autotune” methodology under development for calibrating building energy models (BEM). It is aimed at developing an automated BEM tuning methodology that enables models to reproduce measured data such as utility bills, sub-meter, and/or sensor data accurately and robustly by selecting bestmatch E+ input parameters in a systematic, automated, and repeatable fashion....

Bounding ground state energy of Hopfield models

In this paper we look at a class of random optimization problems that arise in the forms typically known as Hopfield models. We view two scenarios which we term as the positive Hopfield form and the negative Hopfield form. For both of these scenarios we define the binary optimization problems that essentially emulate what would typically be known as the ground state energy of these models. We t...

Energy Conservation in Building

The building sector accumulates approximately a third of the final energy consumption. Consequently, the improvement of the energy efficiency in buildings has become an essential instrument in the energy policies to ensure the energy supply in the mid to long term moreover is the most cost-effective strategy available for reducing carbon dioxide emissions This paper is studying the main objecti...

Accuracy, Validity and Relevance of Probabilistic Building Energy Models

An Approach to the Calibration of Building Energy Simulation Models

As part of the model validation and development activities of a European research initiative in the area of passive solar architecture, a validation/calibration methodology has been developed which emphasises the use of empirical data in the model proving process and, if necessary, model calibration before use. This procedure has been applied to the ESP-r system in order that it might be used t...
