The new European Directive EPBD (Energy Performance of Building Directive) and the added value of the photovoltaic system
Session
Energy Efficiency Engineering
Description
With the "green houses" directive, the European Union intends to reduce harmful gasses emissions by 55% to 2030 compared to 1990 levels and achieve zero emissions by 2050, with the aim of redeveloping the European building stock and improving its efficiency energy.
The provision advanced by the European Commission has been included in the Fit for 55 reform package and has the objective of acting as a priority on the 15% of the most energy-intensive buildings (located in energy class G) for each Member State; in Italy there are approximately 1.8 million residential buildings, out of a total of 12 million. The need to increasingly electrify domestic services can only pass through the installation of photovoltaic systems. In fact, if on the one hand these lead to an immediate benefit in terms of energy savings (linked to the reduction of the cost in the bill), on the other hand the calculation of the energy requirement if combined with a heat pump, means that the thermal contribution for the share of heating, cooling and domestic hot water production, inside the building is almost zero (or zero based on the sizing of the building/plant system). This article will analyze a 120 square meter building (well insulated, equipped with a hybrid heat pump), with an 8 kW photovoltaic system with 15 kWh of storage batteries, and without the photovoltaic system and storage, demonstrating how the energy class and the consumption of the property, can radically change in the two configurations.
