ABSTRACT

"OVER TIME, THE LARGE SHOPPING MALLS IN MACAO WILL REQUIRE SOME CHANGES TO IMPROVE SPACE UTILIZATION, RESULTING IN RENOVATION PROJECTS THAT AFFECT INDOOR PARTICULATE MATTER (PM10 AND PM2.5) CONCENTRATIONS. EMPLOYEES WORK LONG HOURS IN AN ENVIRONMENT WHERE THE AMBIENT AIR QUALITY IS POOR, DIRECTLY AFFECTING THEIR WORK EFFICIENCY. NONETHELESS, THE CONCENTRATION OF PM PRODUCED BY THE INTERIOR RENOVATION OF SHOPPING MALLS HAS YET TO RECEIVE PARTICULAR ATTENTION. THEREFORE, THIS STUDY WILL INVESTIGATE IAQ, IN PARTICULAR, PM10 AND PM2.5 IN LARGE-SCALE SHOPPING MALL RENOVATION PROJECTS IN THREE DIFFERENT INDOOR LOCATIONS (I.E., PUBLIC, RENOVATION, AND CONSTRUCTION AREAS) TO UNDERSTAND THE CAUSES OF INDOOR PM10 AND PM2.5. THIS STUDY WILL COLLECT ON-SITE PM DATA FOR ANALYSIS, EXAMINE WHETHER THE CURRENT CONTROL MEASURES ARE APPROPRIATE AND PROPOSE SOME IMPROVEMENTS. THE DATA COLLECTED WILL BE COMPARED WITH IAQ STANDARDS FROM THE WORLD HEALTH ORGANIZATION (WHO) AND THE MACAO METEOROLOGICAL AND GEOPHYSICAL BUREAU (SMG), SPECIFICALLY PM CONCENTRATIONS. THE RESEARCH RESULTS CAN PROVIDE A REFERENCE GUIDE FOR DECISION-MAKERS, MANAGEMENT, CONSTRUCTION TEAMS, DESIGN CONSULTANT TEAMS AND RENOVATION TEAMS OF LARGE-SCALE PROJECTS. IN ADDITION, THE MONITORING OF IAQ CAN ENSURE A COMFORTABLE ENVIRONMENT FOR EMPLOYEES AND CUSTOMERS."
