Abolfazl Hayati är teknologie doktor i energisystem och inneklimat (2017) vid Högskolan i Gävle (HiG). Han har en masterexamen i energisystem (2012) från HiG samt ingenjörsexamen i maskinteknik (Mechanical engineering) (2009) från Tehran Polytechnic.
Dr Abolfazl Hayati har varit involverad i forskning vid Högskolan i Gävle både under doktorandstudierna som en del av projektet ”Spara och bevara” (Dnr 2011-002440) tilldelat av Energimyndigheten och efter examen som universitetslektor. Hans forskning handlar om fjärrvärme- och fjärrkyla system, byggnadsenergisystem, energieffektivitet, inneklimat, miljöbedömning av byggnader, naturlig ventilation, stadsventilation och solenergi. Undersökningar inkluderar mätningar (i laboratorium, fält- och vindtunnel), analytisk modellering och numeriska simuleringar med byggnadsenergisimuleringsverktyget IDA-ICE. Dessutom översiktlig erfarenhet av CFD simulering (luftströmning i utrymmen) med ANSYS Fluent.
Som universitetslektor har Abolfazl varit inblandad i undervisning och handledning på högskolan som föreläsare/kursansvarig och labbhandledare i olika kurser på högskoleingenjörs- och mastersnivå. Abolfazl har också varit handledare till några examensarbeten (Länk till exjobbarbetena) samt bi-handledare till doktorander sedan 2017.
