ACER and the MULTICARE Virtual Demonstrator

About ACER

ACER (Agenzia Campana per l’Edilizia Residenziale) is responsible for implementing housing policies in the Campania Region, focusing on urban regeneration and public housing improvements. It manages approximately 60,000 properties out of Campania’s total 110,000 public housing units, with a significant concentration—72,000 units—in the Metropolitan City of Naples. Many of these buildings are outdated, requiring substantial upgrades to meet modern seismic safety and energy efficiency standards.

The National Recovery and Resilience Plan (PNRR) and its Complementary Funds are driving a major renovation programme for Campania’s public and social housing. ACER will lead multiple regeneration projects to enhance the safety, efficiency, and sustainability of these properties.

The MULTICARE Virtual Demonstrator

As part of the MULTICARE project, ACER will develop a virtual demonstrator to assess the impact of multi-hazard resilience strategies across its housing portfolio. The demonstrator will:

> Analyse the neighbourhood where the physical demonstration takes place.
> Expand the assessment to the city and provincial level to evaluate broader impacts.
> Collect data on current energy performance of existing buildings.
> Apply the Spatial Decision Support System (SDSS) to model MULTICARE intervention strategies.
> Compare before-and-after scenarios to determine the effectiveness of resilience-based renovations.

This approach will support ongoing and future renovation efforts, offering insights for regional-scale upgrades and potential national replication.

Replication Potential

The intervention has a high replication potential at the city, regional, and national levels. In Italy:

> 30% of the national building stock consists of concrete structures with hollow bricks.
> 1.64 million buildings were constructed in the same period as the demo site, and only 40% have been refurbished.

At the European level:

> 35% of buildings were built in the same time frame.
> In Portugal, 49% of buildings follow this construction typology, with 671,147 buildings dating from 1970-1990 (39% of the total stock).
> Similar trends exist in Greece (50%), Romania (25%), and across Spain, Slovenia, Germany, the Netherlands, Belgium, and Ireland.

By demonstrating scalable, data-driven solutions, ACER’s work in MULTICARE will serve as a model for urban renewal and resilience strategies across Europe.
