Building Energy Models in the Operational Phase: Automation of the Model Calibration Process

Building Energy Models, which consider all energetic aspects of a building’s performance, are a beneficial tool for use in a building’s design and operational stage to optimise the design or performance of a building, aid in decision making, and carry out code compliance. Model calibration is a term which refers to the improvement in the performance of a BEM simulation to better match the actual building in design or operation, which will in turn improve the results in using the BEMs in their various applications. Model calibration is particularly relevant in a building’s operational stage considering that, as well as the number of dynamic elements involved in a building’s performance on a day-to-day basis, buildings quite often perform differently to the initial design intent. Despite the benefits, model calibration is a time-consuming process which typically requires expert user knowledge. This paper details a methodology focused on improving and automating elements of the calibration process to address these current known limitations.

Assessing the Photovoltaic Potential of Flat Roofs: Insights from the Analysis of Optimised Array Arrangements

PV installations on flat roofs offer a wide range of design options, which are usually neglected in urban-scale assessments as these typically assume horizontal or other fixed arrangements. In this study, we analyse the influence of common design parameters (tilt and inter-row distance) in evaluating the potential of PV arrays installed on flat roofs, using three different performance indicators. By comparing optimised arrangements to horizontal ones, we show that the latter could be misleading, unless building- and indicator-specific correction coefficients are applied.


2:10pm - 2:20pm

Wooden windows in the historic alpine architecture: Balancing energy and conservation needs

Daniel Herrera, Dagmar Exner, Marco Larcher, Alexandra Troi

EURAC research, Italy

Energy performance of historic buildings is an urgent matter, but mass implementation of efficient measures faces several challenges (namely, conservation, durability, or comfort). This paper presents the results of a multidisciplinary study of wooden windows in alpine buildings. Different approaches are needed depending whether the original window is maintained or substituted. In the first case, the results of a desk-based study led to the proposal of two new strategies of intervention. In the latter, an interdisciplinary workshop allowed highlighting the deficiencies of current practice whereas simulation results supported the definition of new approaches to address them.
