Is the set of EPB standards mandatory in Europe?

Annex I to the EPBD  sets out a common general framework for calculating buildings’ energy performance and, inter alia, describing national methodologies. To meet the objectives of energy efficiency policy for buildings, energy performance certificates (EPCs) should be made more transparent by ensuring that all necessary calculation parameters, both for minimum energy performance requirements and […]

Please explain what is the “energy efficiency first” principle? Can you give an example regarding PV: is exported PV included or is it related only to energy savings?

Putting energy efficiency first is important, as energy savings are the easiest way of saving money for consumers and to reduce greenhouse gas emissions. Which measures are needed to save energy, by decreasing the energy need (e.g. the building envelope) and the energy use (the technical building systems), can be calculated with the help of […]
