Description

Several energy efficiency concepts and comfort models emerged in the last 15 years seeking high performance buildings and optimal occupant comfortconditions. The aim of high performance buildings is to reduce the carbon footprint and energy consumption of buildings while maintain a fit to purposecomfort. In this context, this work raises the question of fir to purpose comfort models that can from one side reduce the energy consumption of typical officebuildings in hot climates (cooling dominated) while on the other side ensuring indoor thermal comfort. Indeed, studies that address energy efficiency aremany, however it is in most cases applied to temperate or cold climates and barely explored for hot climates. The objective of this paper is to (1) combineseveral comfort models for a net zero energy building in hot climates, (2) select the comfort model that shows the optimal comfort quality of indoorenvironment and (3) compare the building’s annual energy consumption for each used comfort model. To respond to our research problems, a methodologyhas been established, which goes through several phases. First identifying the different comfort models comfortable to use in hot climates (ISO 7730 /EN 15251 / adaptive ASHRAE / Givoni), secondly selecting a typical validated office building model as a reference building and finally selectingrepresentative cities in the Mediterranean arid and hot climate (Algiers / Sicily / Cairo / Dubai). The study used building performance simulation togenerate the different results on the energy consumption and the operative temperatures of the different models of comfort in each city. The paper ultimatelyidentifies the fit to purpose comfort models for a medium size net zero energy office building in hot climates. The paper presents a comparison that can helpbuilding professional to identify the most appropriate comfort model that allows optimizing energy consumption, ensuring thermal comfort for robustperfromnce of net zero energy buildings in hot climates.
