Renovating Apartment Buildings For Energy Self-Sufficiency

An innovative logic of the charge and discharge of the two storages as a function ofenergygeneration and demand has been developed with the aim to optimize the energeticself-sufficiencyof typical residentialbuildings.

Challenges can be mitigated by introducing thermal and electrical storage to increase theself-consumption of renewableenergyin thebuildings. This work proposes a comparison between differentenergysystems equipped with a heat pump, solar plant (photovoltaic or photovoltaic thermal), and thermal and electrical storage.

Build-in flexibility to maximiseenergyself-sufficiencySimply meeting a positive annualenergybalance is not enough to ensure optimal environmental performance or efficientbuildingoperations.

As we can see from the illustration, Renovating Apartment Buildings For Energy Self-Sufficiency has many fascinating aspects to explore.

To reach the EU 2030 goal of reducing greenhouse gas emissions targets, manyapartmentswithin residentialbuildingscan be equipped with rooftop orbuilding-integrated PV systems. However, as non-programmable renewableenergysources (solar, wind) are characterized by uncertainty and fluctuation, it is very difficult to match the supply with the demand for thebuilding'senergyneeds. Thermal ...

In the selected case study, polycrystalline panels with net metering can achieveself-sufficiencylevels ranging from 18% to 41% for residential blocks. This study confirms that solar PV systems can increase local production, reduce gridenergydependency, and supportenergycommunities.

The world is at a pivotal point in addressing climate change, and the built environment has become a critical arena for transformation.Buildingsaccount for approximately 40% of globalenergyconsumption and 33% of greenhouse gas emissions, according to the United Nations Environment Programme. To tackle this, zero-energybuildings(ZEBs) offer a revolutionary approach to sustainability ...
