Building green covering for a sustainable use of energy

2013

Nowadays the growth of the cities increased built and paved areas, energy use and heat generation. The phenomenon of urban warming, called urban heat island, influences negatively outdoor comfort conditions, pollutants concentration, energy demand for air conditioning, as well as increases environmental impact due to the demand of energy generation. A sustainable technology for improving the energy efficiency of buildings is the use of green roofs and walls in order to reduce the energy consumption for conditioning in summer and improve the thermal insulation in winter. The use of green roofs and walls can contribute to mitigate the phenomenon of heat island, the emissions of greenhouse gas…

Strategies to decrease water drainage and nitrate emission from soilless cultures of greenhouse tomato

2010

In the spring-summer season of 2005 and 2006, we explored the influence of three fertigation strategies (A–C) on the water and nitrogen use efficiency of semi-closed rockwool culture of greenhouse tomato conducted using saline water (NaCl concentration of 9.5 mol m−3). The strategies under comparison were the following: (A) crop water uptake was compensated by refilling the mixing tank with nutrient solution at full strength (with the concentrations of macronutrients equal or close to the corresponding mean uptake concentrations as determined in previous studies) and the recirculating nutrient solution was flushed out whenever its electrical conductivity (EC) surpassed 4.5 dS m−1 due to the…

Agroalimentare e sviluppo economico sostenibile: energia, efficienza energetica, ambiente e cibo

2013

Nell’ultimo decennio, il sistema agroalimentare nazionale nella sua accezione più ampia di agricoltura e industria alimentare, ha assunto una configurazione fortemente sistemica, aperta al contributo di diverse discipline e tecnologie. Tale evoluzione ha consentito al sistema agricolo di raggiungere posizioni ragguardevoli se consideriamo che nel complesso l’agroalimentare rappresenta per l’economia italiana un valore di 250 miliardi €, pari a circa 16% del PIL. Il mondo agricolo, nel suo complesso, costituisce ormai uno snodo fondamentale per attività che riguardano: l’energia, l’ambiente, il cibo, il territorio, il benessere dei cittadini, il sistema economico aree urbane-aree rurali. Il …
