Under strict economical constraint, the concept of " lean regeneration ", i.e. the achievement of high energy performance by improving the building envelope using innovative but not too sophisticated technologies, has been applied in a 52 dwelling units block. Increased insulation thickness, advanced glazing, preheating of ventilation air in glazed balconies, water saving and improving the district heating loop control have been implemented. The objective is to reduce the heating load by 60%. The dwelling block is heated by a district heating using mainly coal fuel, and it is hoped to reduce a large amount of CO 2 emissions. This regeneration project is part of a more global urban project according to an environmental agenda defined by the municipality. The measured heating energy consumption is 25% lower after renovation instead of the 60% reduction estimated by the calculation. The analysis leads to identify various causes and to propose some improvement. The measured indoor temperature is higher after renovation (+3°), which should increase the heating load by 22%. It was therefore proposed to lower the heating loop temperature. The ground floor is heated after renovation, leading to additional energy consumption (+25% estimation). If we correct the measured value to account for this bias, we obtain a 50% reduction after renovation, leading to a 70 kWh/m 2 /y heating energy consumption. These results show the specificity of existing buildings compared to new construction : complementary measures are needed to improve the performance (e.g. glazing all balconies to reduce thermal bridges and preheat ventilation air). The pay back time is estimated from around 2 years for low emissivity glazing, up to 20 years for increasing the insulation thickness, but some techniques are still not economical (glazed balconies, active solar), also due to the fact that no support could be obtained at a regional level. A life cycle assessment has been performed and a 50% reduction of CO 2 emissions has been estimated. It was also suggested to lower the use of coal in the district heating system using partly wood as a fuel. Some innovative techniques like advanced glazing are very efficient and the dissemination activities will hopefully influence other decision makers in the social housing sector, leading to partial replication of this project.

In this context, this paper presents an ecodesign approach of a plus-energy house assisted by multicriteria optimisation. Illustrated by a real case, this approach uses a genetic algorithm to find a set of solutions as close as possible to the theoretical Pareto front, corresponding to the best compromises for the formulated problem. The solutions' performance was evaluated using a dynamic building energy model (COMFIE), a life cycle analysis model (novaEQUER), and a construction cost database. In order to study the solutions' robustness, the diversity of occupants' behaviour was stochastically modelled. The proposed approach is thus contributing to the decision making process, beyond simple evaluation by simulation.

Research paper thumbnail of Derivation of simplified control rules from an optimal strategy for electric heating in a residential building

In this context, advanced control systems could improve buildings energy management. More specifically, optimal strategies have been developed using a dynamic programming method in order to shift heating load, taking advantage of the building thermal mass. However, this optimisation method is computationally intensive and can hardly be applied to real-time control. Statistical techniques can be used to derive near-optimal laws from the optimal control results. These rule extraction techniques model the relationship between explanatory variables and a response variable. This paper investigates the use of Beta regression model. This regression-based strategy was able to mimic the general characteristics of the optimisation results with a small mean bias error (-6 %) and greatly reduce computational effort (150 times faster). Given its simple mathematical formulation, it could be implemented in real-time building systems control.

L'aménagement du quartier, la forme, la hauteur et l'emplacement des bâtiments ont une influence sur les aspects thermiques et environnementaux des projets. La conception paramétrique complétée d'une analyse de cycle de vie (ACV) est un moyen de comparer les impacts environnementaux de différentes variantes de bâtiments et ainsi d'optimiser leur forme lorsque cela est encore possible, dès l'esquisse du projet. Cette communication présente le développement d'un couplage entre un logiciel de conception paramétrique Rhino-Grasshopper et l'outil de simulation thermique dynamique et d'ACV Pleiades, afin de proposer des projets urbains à faibles impacts environnementaux. La compacité des bâtiments, les masques solaires et les matériaux liés à la structure sont des paramètres pris en compte dans ce couplage. Une application à un cas d'étude a permis de comparer les impacts environnementaux d'une tour de bureaux et de trois bâtiments de 10 étages, pour une même surface utile.

L'article présente une méthode d'optimisation multicritère (critères de consommation d'énergie finale et de coût d'investissement relatif) basée sur un algorithme génétique NSGA-II couplé à un modèle de simulation énergétique dynamique (COMFIE). La méthode est appliquée à un cas d'étude de type maison passive situé en Bulgarie, dans le cadre du projet européen AZEB (Affordable zero energy building), afin de déterminer des solutions zéro-énergie à moindre coût d'investissement. Des conceptions de différents niveaux de performance sont identifiées au sein du front de Pareto dont les impacts environnementaux sont évalués par analyse de cycle de vie (ACV, Equer). Les résultats montrent que pour identifier des solutions à énergie positive efficientes en termes de coûts et d'impacts environnementaux et éviter d'aboutir à des conceptions sous-optimales, il est recommandé d'intégrer à l'algorithme d'optimisation une fonction objectif tirée de l'ACV ou de compléter l'optimisation par une étude ACV. MOTS-CLÉS : optimisation multicritère, analyse de cycle de vie, bâtiment zéro-énergie ABSTRACT. This article presents a multicriteria optimization method (criterias of final energy consumption and relative investment costs) based on a genetic algorithm (NSGA-II) coupled with a building performance simulation model (COMFIE). The optimization is applied to a passive house case study based in Bulgaria in the frame of from the european project AZEB (Affordable zero energy building). Designs from different levels of performance have been identified among the Pareto-optimal front and life cycle analysis (LCA, Equer) has been applied to assess their environmental impacts. LCA results analysis steer a recommendation to include an LCA objective function in the optimisation process or to complete optimisation study with LCA in order to identify energy plus solutions that are efficient in terms of cost and environmental impacts, and in order to avoid sub-optimal designs.

In order to reach this goal, such tools need to be robust. However, practitioners are facing many choices in a project, leading to uncertainties in the results. In order to understand which factors induce the most uncertainty, sensitivity analysis (SA) is commonly applied, followed by uncertainty analysis (UA). Of particular interest is the possible influence of the uncertainty on the ranking of compared alternatives.

Research paper thumbnail of Dynamic and consequential LCA aspects in multi-objective optimisation for NZEB design

IOP conference series, Nov 1, 2020

Multi-objective optimisation coupled with building energy simulation (BES) and life cycle assessm... more Multi-objective optimisation coupled with building energy simulation (BES) and life cycle assessment (LCA) models is a promising method to eco-design net-zero energy buildings (NZEBs) in line with sustainable objectives such as UN SDG’s goals 7, 11, 12 and 13. This paper presents a method of building multi-objective optimisation based on NSGA-II coupled with the BES model COMFIE and the building LCA tool EQUER to identify NZEB designs that minimise construction costs and GHG emissions. A dynamic electricity mix model was implemented in LCA to evaluate more precisely time-related impacts of heating and solar photovoltaic production. Three different LCA approaches defining the multi-objective optimisation problem were compared: static LCA (considering an average annual electricity mix), dynamic attributionnal LCA (average hourly mix) and dynamic consequential LCA (marginal hourly mix). Results show minor differences in optimums quality between static and dynamic attributionnal approaches but important differences in optimums design parameters between attributionnal and consequential approaches. The influence of the LCA approach on multi-objective optimisation results emphasises the need to specify guidelines for practitioners about the choice of the LCA approach.
