Abstract - Using vertical greenery systems to reduce heat transmission is becoming more common in modern architecture. Vertical greenery systems are divided into two main categories; green facades and living walls. This study aims to examine the thermal performance of vertical greenery systems in hot and humid climates. An experimental procedure was used to measure indoor temperature and humidity. These parameters were also measured for the gap between the vertical greenery systems and wall surfaces. Three boxes were used as small-scale rooms. Two boxes were provided with either a living wall or a green facade and one box did not have any greenery (benchmark). Blue Trumpet Vine was used in the vertical greenery systems. The data were recorded over the course of three sunny days in April 2013. An analyses of the results showed that the living wall and green facade reduced indoor temperature up to 4.0 °C and 3.0 °C, respectively. The living wall and green facade also reduced cavity temperatures by 8.0 °C and 6.5 °C, respectively.

This study has focused on post occupancy evaluation of green facade for elementary school classroom in Taiwan to appreciate the actual situations and usage problems for green facades. This study has chosen three schools for case study. Based on field measurement, and user interview and user questionnaire, they are being used to clarify the environment improvement contributed by green facade establishment and its effectiveness of environment education of each case. This study also found usage and maintenance and management problems derived from green facade installed. Results show that the effectiveness of green facades on the classroom indoor environment improvement is partial significant, on the environment education is not as good as anticipated and on the maintenance and management have many problems and some unexpected negative effects. According to the above results, this study proposes relative planning and designing suggestions as a reference for schools that are willing to have green facades establishment in the future.

Abstract. The heterogeneity of Agroecosystems, in terms of hydric conditions, crop types and states, and meteorological forcing, is difficult to characterize precisely at the field scale over an agricultural landscape. This study aims to perform a sensitivity study with respect to the uncertain model inputs of two classical approaches used to map the evapotranspiration of agroecosystems: (1) a surface energy balance (SEB) model, the Two-Source Energy Balance (TSEB) model, forced with thermal infrared (TIR) data as a proxy for the crop hydric conditions, and (2) a soil–vegetation–atmosphere transfer (SVAT) model, the SEtHyS model, where hydric conditions are computed from a soil water budget. To this end, the models' skill was compared using a large and unique in situ database covering different crops and climate conditions, which was acquired over three experimental sites in southern France and Morocco. On average, the models provide 30 min estimations of latent heat flux (LE) with a RMSE of around 55 W m−2 for TSEB and 47 W m−2 for SEtHyS, and estimations of sensible heat flux (H) with a RMSE of around 29 W m−2 for TSEB and 38 W m−2 for SEtHyS. A sensitivity analysis based on realistic errors aimed to estimate the potential decrease in performance induced by the spatialization process. For the SVAT model, the multi-objective calibration iterative procedure (MCIP) is used to determine and test different sets of parameters. TSEB is run with only one set of parameters and provides acceptable performance for all crop stages apart from the early growing season (LAI < 0.2 m2 m−2) and when hydric stress occurs. An in-depth study on the Priestley–Taylor key parameter highlights its marked diurnal cycle and the need to adjust its value to improve flux partitioning between the sensible and latent heat fluxes (1.5 and 1.25 for France and Morocco, respectively). Optimal values of 1.8–2 were highlighted under cloudy conditions, which is of particular interest due to the emergence of low-altitude drone acquisition. Under developed vegetation (LAI > 0.8 m2 m−2) and unstressed conditions, using sets of parameters that only differentiate crop types is a valuable trade-off for SEtHyS. This study provides some scientific elements regarding the joint use of both approaches and TIR imagery, via the development of new data assimilation and calibration strategies.

The aim of this study was to examine the influence of climate conditions and ripening on total phenols (TP), total monomeric anthocyanins (TAC) and antioxidant capacity (AC) of Maraska and Oblačinska sour cherries. For that reason, TP using Folin-Ciocalteau reagent, TAC by pH-differential method and AC via DPPH method were determined in Maraska and Oblačinska sour cherry samples harvested in Zadar and Osijek area in 2014 at three maturity stages. Despite that statistical analysis showed significant differences in TP and AC between cultivars and growing locations, obtained results revealed considerable functional properties of both cultivars. Still, Maraska achieved higher TP, TAC and AC values compared to Oblačinska. Furthermore, Mediterranean climate conditions positively affected on bioactive compounds accumulation in both cultivars, where generally the highest contents of examined bioactive compounds were accomplished at the latest harvest date.
