This work aims to reduce the energy consumption of existing buildings through retrofitting and converting them into net zero (NZEBs). Various retrofits for an academic building were modeled analyzed using REVIT software. Energy was reduced approximately 34% retrofits, a Solar System 41.6 kW integrated meet demand, consequently (NZEB). Furthermore, environmental economic analyses conducted, resu...

This work presents four-year monitoring results of two new multi-family houses in Innsbruck aiming to be net-zero energy buildings (NZEB). The project combines high-performance designed Passive House standard, highly-efficient HVAC systems i.e., low-temperature distribution and emission, a double-stage ground-water source heat pump including desuperheater mechanical ventilation with recovery, m...

Southern Europe has an old housing stock and the challenge, as rest of European Union Member States, to transform it into a decarbonized one, by means transforming existing buildings Nearly Zero Energy Buildings (nZEB). States have large margin discretion when defining requirements for nZEB. In this paper, nZEB renovation residential in Portugal Spain are studied detail (unlike usual more gener...

The Energy Performance of Buildings Directive (EPBD 2018/844/EU) requires to Member States upgrade the methodology for energy performance assessment buildings. current calculation method, based on monthly quasi steady state procedure, could be replaced in next years by an hourly dynamic procedure (EN ISO 52016), which a resistance-capacity (RC) model is implemented consider with more accuracy h...
