The energy refurbishment of the existing building heritage is one of the pillars of Italian energy policy. Aiming for energy efficiency and energy saving in end uses, there are wide and diversified improvement strategies, which include interventions on the building envelope and Heating, Ventilation, and Air Conditioning (HVAC) systems, with the introduction of renewable energy sources. The research aims at evaluating the building energy consumptions and Indoor Environmental Quality (IEQ), varying the airflow rates handled by the HVAC system.

In the CoViD-19 pandemic, the precautionary approach suggests that all possible measures should be established and implemented to avoid contagion, including through aerosols. For indoor spaces, the virulence of SARS-CoV-2 could be mitigated not only via air changes, but also by heating, ventilation, and air conditioning (HVAC) systems maintaining thermodynamic conditions possibly adverse to the virus. However, data available in literature on virus survival were never treated aiming to this.

In recent years, the Scientific Community and the Public Health world, in general, have devoted increasing interest to housing conditions, which are considered, to date, one of the main environmental and social determinants of the population's health. In particular, the Scientific Community has identified and studied various indoor well-being factors (e.g. lighting, temperature, ventilation, air quality, etc.).

Background and aim of the work: The ongoing pandemic of COVID-19 is a strong reminder that the lockdown period has changed the way that people and communities live, work, and interact, and it’s necessary to make resilient the built environment, both outdoor and mainly the indoor spaces: housing, workplaces, public buildings, and entertainment facilities. How can we re-design the concept of Well-being and Public Health in relation to the living places of the future?

This work investigates the possibility of implementing a nature-based solution (NBS) based on the photosynthetic process of Laurus nobilis L. (common laurel), for reducing peak CO2 concentrations in an air-tight museum environment, namely the Refectory of the Santa Maria delle Grazie Church (Milan, Italy), home of Leonardo da Vinci’s painting “Last Supper”. The phytoremediation potential of laurel plants was evaluated at CO2 ≅ 1000 ppm under controlled environmental conditions.

INTRODUZIONE
La Regione Puglia ha promosso il progetto IM.PA.C.T. (Improving the health of Patients by supporting dynamiC
healTh systems and new technologies), per valutare gli aspetti igienico-sanitari delle sale operatorie (SO). In
questo ambito sono stati indagate le caratteristiche edilizie e impiantistiche che ne influenzano le prestazioni.
METODI
Lo studio ha coinvolto 35 SO ortopediche [17 con flusso misto (FM), 18 con flusso turbolento (FT)]. Sono

Preliminary results concerning the VIEPI (Integrated Evaluation of Indoor Particulate Exposure) project are described. VIEPI project aimed at evaluating indoor air quality and exposure to particulate matter (PM) of humans within workplaces. Infiltration factors of PM in indoor environments of different sizes with different air ventilation regimes as well as their dependence on outdoor and indoor micrometeorology characteristics are some of the goals of the project. For these purposes, several indoor environments located on different sites of the Rome area were considered for the analysis.
