“…Substantial R&D in the past decade has been directed towards reducing costs when placing wall insulation outside of the structural sheathing [14,16,17], but reductions have been hard to come by and significant adoption in the market has not occurred. These efforts at cost reduction and market stimulus are ongoing in the US, with a particular focus on the potential for panelized construction and factory prefabrication technologies [18,93]. While prices remain extremely high for wall insulation exterior to the structural sheathing in existing homes, upgrades occurring at the time of cladding replacement remain a more cost-effective option.…”

Home Energy Upgrades as a Pathway to Home Decarbonization in the US: A Literature Review

This work aims to characterize how home energy upgrade projects and programs in the US have evolved over the past decade. It also identifies what changes are needed to drive expansion of the US energy retrofit market in such a way that addresses carbon emissions from buildings, improves resilience and upgrades the housing stock. This review focuses on whole-home energy upgrades, targeting deep energy retrofit savings of >30%. The topics we cover include trends in home electrification, US and European home energy upgrade programs, energy upgrade measure costs, business economics, and health effects. Key changes in project design noted in this review include: (1) the electrification of dwellings with rapidly improving heat pump systems and low-cost solar photovoltaic technology; and (2) a shift away from high-cost building envelope strategies and towards more traditional home performance/weatherization envelope upgrades. Promising program design strategies covered include: (1) end-use electrification programs; (2) novel financing approaches; (3) the use of carbon-based program and project metrics; and (4) “one-stop shop” programs. Based on the existing market barriers, we suggest that the industry should adopt new project performance metrics. Additionally, market drivers are needed to spur widespread energy upgrades in the US housing stock. Costs must be reduced, and projects designed to appeal to homeowners and contractors.

“…The industrial aspect of the process is also fairly studied (Micelli & Mangialardo, 2017). Some studies focus on transfer to other countries and the feasibility of adapting the Energiesprong model (for the United States, see Egerter & Campbell, 2020). In France, a study illustrates the innovations and transformations for the professions and the actuator systems involved (Pellegrino, 2019).…”

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

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.
