Description:	A sustainable conceptual framework was developed for integrating impacts of indoor air quality on human health into Life Cycle Assessment (LCA) of buildings. The framework was designed using university buildings located at Universiti Kebangsaan Malaysia as a case study. The case study measures the indoor particulate matter (PM10) composition and the equilibrium equivalent radon (EECRn) concentration in two university buildings with different ventilation systems (Building 1 and Building 2). A low volume sampler using Teflon filter paper was used to collect the PM10 samples and inductively coupled plasma mass spectrometry was used to determine the concentration of heavy metals. The potential human health damage due to the inhalation of carcinogenic and non-carcinogenic elements was also determined based on the United States Environmental Protection Agency (US EPA) standard. For the indoor radon, the concentration was measured for 25 sampling stations using radon detector model DOSEman PRO. The results showed PM10 concentrations recorded in Building 1 and Building 2 ranged between 19.1 to 237 µg m-3 and 23.4 to 159 µg m-3, respectively. In Building 1, the principal component analysis (PCA) and multiple linear regression (MLR) showed that the main sources of pollutants in PM10 was the crustal source (20%) and in Building 2 through combustion (21%). The effective lifetime carcinogenic risks (ELCR) in Buildings 1 and 2 were 1.90E-3 and 1.65E-4, which mean the risk of cancer to 1900 people and 16500 people, respectively. It was suggested that different types of ventilation influence the PM10 distribution in buildings and associated risks towards the occupant's health and indoor air quality. Results also indicate that the average equilibrium equivalent radon measured in the Building 1 and Building 2 were 2.33 ± 0.99 and 3.17 ± 1.74 Bqm-3, respectively. The indoor air quality data obtained were used as baseline information to establish the relation between indoor air quality and human health damage following an LCA approach.,Certification of Master's/Doctoral Thesis" is not available
