Social Housing Net-Zero Energy Renovations With Energy Performance Contract: Incorporating Occupants’ Behaviour

Abstract

This article examines how the behaviour of occupants is assessed in a project with ambitious targets for energy use reductions and within the framework of an approach based on an energy performance contract. Its starting point is the observation that there may be significant disparities between the consumption threshold required by the regulations or the labels and the actual building consumption in its post-delivery existence. While behaviour cannot be the only factor explaining this overconsumption, the promoters of high-performance renovation operations often marginalise their importance. The recent surge in requirements for energy consumption reductions in new or renovated buildings in Europe further exacerbates these problems. In light of these challenges, there is a strong demand for compulsory verification of post-delivery performances and for developing energy performance contracts. In this context, the behaviour of a building’s occupants can no longer be considered as a simple adjustment variable. Through the analysis of Energiesprong, a net-zero energy renovation approach for the social housing developed in the Netherlands and in France, built around the principle of an energy performance contract over a long timeframe, the article highlights the injunctions to behavioural changes, the strategies, the negotiations, and the adjustments deployed by the project leaders. It finally shows that there is still a long way to go before the occupant’s behaviour in a high-energy performance renovation project is fully taken into account.

“…Such renovations require local government and developer investments aimed at delivering healthier living spaces and in turn, help reduce dependence and cost pressures on health services. (Pellegrino, Wernert, & Charti, 2022) .…”

Everyday sustainability transitions through using green buildings: Spatial perspectives on materialities, discourses, and lived sustainabilities

“…solar panels) (Li et al, 2021). Much less emphasis has been placed on understanding the sustainability of green buildings once they are in use, including broader implications for daily lives (Affolderbach and Schulz, 2018; Pellegrino et al, 2022; Thatcher and Milner, 2016). While reducing material and energy consumption of buildings is crucial in tackling climate change, taking a fabric-only approach to sustainability in the built environment overlooks the significant impact of “users” on energy consumption and thus emissions (Bardsley et al, 2019; Breadsell et al, 2019).…”

Identifying Home System of Practices for Energy Use with K-Means Clustering Techniques

“…The focus has been shifted to the study of the societal factors of energy consumption and understanding how energy use is constituted socially and materially [10][11][12][13][14][15][16][17][18]. This is accompanied by understanding the attitudes, behaviours, and choices of individuals that relate to the context of energy consumption [19,20]. These behaviours correlate to the practices performed by individuals in order to achieve certain social outcomes.…”
