Vertical vegetation systems are an innovative passive method for decreasing the thermal energy demand of buildings while increasing quality urban life. The main objective this work is to calculate effectiveness in reducing loads analytically. For purpose, performance modular living wall was compared with a traditional double façade construction system evaluate influence using Stochastic Differential Equations models. research carried out experimentally real-scale PASLINK test cell. behaviour leaf bare and same converted into were calculated different summertime wintertime periods. In both studied cases, temperature exterior surface taken at place regardless whether or not there greenery balance. With simplification, effect can be identified within estimated coefficients. resistance conventional increased 0.74 (m2 K)/W over non-greened wall, which represents weighted increase 49%. Additionally, experimental results showed that evapotraspiration processes take lead combined convection-radiation coefficient, reduces overheating façade. Moreover, effective solar absorptivity value outermost has been reduced 85% thanks confirms high capacity reduce heat gains.

The proposed study investigates the effect of urban heat island mitigation scenarios by applying extensive green roofs, façades, and living walls to two built areas within Turin Rome, Italy. Three a baseline one have been developed in ENVI-met software for each area run typical winter day, summer day with wave. simulation results show that building integrated vegetation technology-application on single has an irrelevant local temperatures; contrariwise, technology-wide application can effectively mitigate warming. Furthermore, roofs temperature is negligible winter, likely because limited plant activity reduced amount incoming solar radiation. Results also façades are more effective than mitigating pedestrian-level air when installed high-rise buildings, beneficial canyons parallel wind direction perpendicular ones. Depending scenario, average decreases temperatures up 1 °C be reached whole selected area, alleviating

Influence of the Representative Concentration Pathways (RCP) scenarios on the bioclimatic design strategies of the built environment

Sustainable Cities and Society, Journal Year: 2021, Volume and Issue: 72, P. 103042 - 103042

Over time, whether through traditional knowledge or the constructive implementation, relationship of built environment with climate conditions a certain place has been developed. The control these symbiotic solutions based on climate-conscious design and their strategic approach have improved to keep better welfare levels. Due change, however, strategies could be modified in context global warming. This research considers Representative Concentration Pathways (RCP 2.6, 4.5 RCP 8.5) analyse effectiveness throughout 21 st century. A total 6 countries (France, Portugal, Spain, Argentina, Brazil, Chile) were selected assess both thermal comfort levels need for using HVAC systems each zone all future scenarios, so 1,450 cases studied. results showed that less conservative change scenarios will affect comfort, thus significantly reducing hours warm climates. In addition, passive effective future, predominating use cooling systems. As result this research, should dynamic permeable possible scenarios.
