“…we refer the reader to the supplementary material for a verification of conservation of energy and to Jorissen et al (2018c) for a verification using BESTEST. Moreover, this gap between model simulations and measurements is a well-known aspect of building energy simulations (Gorse et al 2016;Jones et al 2015). We therefore expect that other BES tools will return similar results.…”

Modelica is a promising open-source modelling language for simulation and derivative-based optimisation of multi-zone buildings, including detailed pressure-driven flow networks and building controllers. Such Modelica models have however not yet been demonstrated for buildings with many zones and complex HVAC systems. This paper presents and provides implementation details of the simulation model of a 32-zones building model in Modelica, with pressure-driven flow networks and a building controller, demonstrating the potential of Modelica. The modelling approach and computational aspects are presented. Furthermore, the model is calibrated and verified using on-site measurement data, which shows that, for the presented case study, HVAC can be modelled with errors up to only a few percent, while larger errors are observed for the building envelope model. A detailed building description is provided as supplementary material.

“…Alternatively, Finite Element (FE) analysis software is relied upon to simulate construction scenarios, numerically modelling the multi-dimensional heat-transfer, crucially capturing temperature and heat flux distributions through the geometry with which the TB-transmittances can be quantified. The metrics generated can then be more accurately utilised in whole building energy modelling (C. Gorse et al, 2016) or included in Standard Assessment Procedures (SAP) tools for Buildings Performance Evaluation (BPE) -which has a recently updated standard BS 40101:2022 (BSI, 2022)compared with the current methods using generic off-the-shelf linear-transmittances values (BS EN ISO 14683 (BSI, 2017h)).…”

Foreword by Professor Richard Fitton, Professor William Swan and Oliver FarrellThis PhD thesis is the work of Joe Pemberton, who was working in a collaboration between the University of Salford and Farrat Isolevel. Unfortunately, on the 17th of April 2023 Joe passed away unexpectedly. He was very near the completion of his PhD, with his viva already arranged. The supervisory team, Professor Richard Fitton and Professor Will Swan, compiled the latest version of Joe's PhD, which was submitted to the external examiners. This version is entirely Joe's work, as such there are a few small gaps. However, Joe had undertaken a considerable amount of work to an exceptionally high standard, which the examiners identified as deserving of a posthumous award.Richard, Will and Oliver Farrell, CEO of Farrat Isolevel, are proud of the work Joe undertook with us and are pleased that we have had the opportunity to publish this thesis on Joe's behalf If you have any queries regarding Joe's work, please contact

“…Dynamic simulation is however far less accurate in predicting the absolute performance of the chosen design [1]. This inaccuracy is caused by differences between the actual building and the representation of its properties in the simulation model.…”

Reducing Simulation Performance Gap in Hemp-Lime Buildings Using Fourier Filtering †

Abstract:Mainstream dynamic simulation tools used by designers do not have a built-in capability to accurately simulate the effect of hemp-lime on building temperature and relative humidity. Due to the specific structure of hemp-lime, heat travels via a maze of solid branches whilst the capillary tubes absorb and release moisture. The resultant heat and moisture transfer cannot be fully represented in mainstream simulation tools, causing a significant performance gap between the simulation and the actual performance. The author has developed an analysis method, based on a numerical procedure for digital signal filtering using Fourier series. The paper develops and experimentally validates transfer functions that enhance simulation results and enable accurate representation of behaviour of buildings built from hemp-lime material using the results of a post-occupancy research project. As a performance gap between design simulation and actual buildings occurs in relation to all buildings, this method has a wider scope of application in reducing the performance gap.
