La documentazione contabile di cantiere consente di indagare non solo lo sviluppo tecnico della f...abbrica (consistenza, materiali, tecniche costruttive), ma anche la vita sociale (gerarchie dei salari, competenze professionali, ruolo della committenza, rapporti di potere, condizioni di genere) e l’impatto ambientale delle diverse azioni in cui si organizza la “macchina” territoriale (reperimento delle materie prime, trasporti e attività logistiche, sopralluoghi ecc.

This paper aims to propose a procedure for calculating the energy performance indexes of buildings considering the seasonality of internal gains due to artificial lighting with a monthly quasi-steady-state energy balance. The proposed methodology evaluates the heat gains due to the integrated natural-artificial lighting system with the Lighting Energy Numerical Indicator (LENI). For the evaluation of buildings’ global energy performance and for some energy services, this contribution cannot be considered constant annually as depend strongly by climate conditions.

The EU building stock is 97% not energy efficient and the promotion of energy retrofitting strategies is a key way of reducing energy consumptions and greenhouse gas emission. In order to improve the energy performance of buildings, the European Union released the Energy Performance of Buildings and the Energy Efficiency Directives.

It is common practice, in the production of photovoltaic energy to only use the south-exposed roof surface of a building, in order to achieve the maximum production of solar energy while lowering the costs of the energy and the solar technologies. However, using the south-exposed surface of a roof only allows a small quota of the energy demand to be covered. Roof surfaces oriented in other directions could also be used to better cover the energy load profile.

In Cuba, more than 50 % of the electricity generation capacity is based on small-scale distribute...d power plants, which guarantee the energy supply-demand from fossil fuels. Several negative environmental impacts are associated with this, including contamination by oily residuals.

Environmental pollution is one of the main environmental problems. The objective was to evaluate ...the management of wastewater in the enterprise sector of Cienfuegos and to propose solutions to mitigate the contamination.
