HVAC Equipment Efficiency
NC-2009 EAp2:Minimum Energy Performanceposted by Ricardo Sobral on
Dear LEED Users, Does anybody know if the minimum HVAC equipment efficiencies listed in Tables 6.8.1 of Standard 90.1 apply to the generator (i.e chiller, boiler, heat pump) or to the whole HVAC
modeling with air cooled chiller
NC-2009 EAp2:Minimum Energy Performanceposted by sherif el adly on
the building size is mandating to model the baseline with a water cooled chiller and I will compare the baseline with the design which is using HVAC that is (air cooled chiller + ice storage + dive
Mini-split efficiency
NC-2009 EAp2:Minimum Energy Performanceposted by Leandro Silva on
We are having trouble verifying the efficiency compliance of mini-split air conditioners available in Brazil. They are rated in COP where ASHRAE requirements are stated in SCOP.
