Abstract

The paper gives a directive toward assessment of resilience of building designed to comply the nearly zero energy standard in the current conditions and also points out the gap in the existing approach for evaluating the effect that the climate changes could have on building material behavior and systems degradation. A method is introduced for evaluating how the variation of energy need and in-situ production can modify the energy balance under the representative concentration pathway of the intermediate (RCP 4.5) and the worst emissions scenario (RCP 8.5). The results for a case study indicate that under RCP 4.5 scenario, the polyethylene foam insulation has the higher increment of heating demand (+ 9.8%) instead the cooling demand decreases by −4.2% (RCP 8.5) and −4.6% (RCP 4.5). The innovative materials are less affected (<1%) by temperature variations. On the other hand, the PV system degradation causes the reduction of in-situ production from −6.9% (RCP 8.5) and −8.0% (RCP 4.5). However, the analysis of the hourly balance suggests that the building resilience would be not compromised. Indeed, by evaluating the ratio between the self-consumption and the total request, it increases compared to the current conditions of around 2%. [ABSTRACT FROM AUTHOR]

Abstract

The paper proposes the experimental characterization of a wall package made of geopolymer concrete and phase change materials (PCMs) in the climate of south Italy. Data collected from May to July 2021 were presented by elaborating surface temperatures and heat fluxes with the introduction of several new indices as the thermal stress reduction amplitude, the percentage of time in melting range and the extreme surface solicitations. The results indicate that the PCMs reduce the thermal solicitation and preserve the geopolymer blocks. The indoor surface temperature can be lowered also of 3°C during the hours with maximum sol-air temperatures and this could contribute to reduce the local discomfort phenomenon. Globally, the heat flux monitored on the geopolymer layer behind the PCM is attenuated and its trend is more regular; this reduction implies a reduction of heat gains through the opaque building envelope and finally a reduction of the energy demand.
