PARAMETRIC ANALYSIS ON COOLING SET POINT TEMPERATURE IN RESIDENTIAL APARTMENTS IN BEIRUT CITY

Abstract

This study examines the potential impact of different configurations of building envelope material including external walls and windows on the final cooling energy consumption in a typical residential apartment in Beirut city that uses conventional DX split units in living room and bedroom zones using HAP software. MED-ENEC study is used to benchmark the Business as Usual (BAU) construction scenario of a case study apartment simulated in HAP that uses single walls and single glazing for windows. After the HAP (BAU) model is validated with MED-ENEC at 78 kWh/m2.year, five different scenarios that include different envelope configurations are simulated to assess possible energy savings, cost savings from EDL and generator subscription, in addition to CO2 emissions reduction.
