BACKGROUND Indoor air pollutants (IAPs) cause multiple health impacts. Prioritizing mitigation options that differentially affect individual pollutants and comparing IAPs with other environmental health hazards require a common metric of harm. OBJECTIVES Our objective was to demonstrate a methodology to quantify and compare health impacts from IAPs. The(More)
BACKGROUND There is broad consensus regarding the health impact of tobacco use and secondhand smoke exposure, yet considerable ambiguity exists about the nature and consequences of thirdhand smoke (THS). OBJECTIVES We introduce definitions of THS and THS exposure and review recent findings about constituents, indoor sorption-desorption dynamics, and(More)
BACKGROUND Residential natural gas cooking burners (NGCBs) can emit substantial quantities of pollutants, and they are typically used without venting range hoods. OBJECTIVE We quantified pollutant concentrations and occupant exposures resulting from NGCB use in California homes. METHODS A mass-balance model was applied to estimate time-dependent(More)

This document describes an energy benchmarking framework for hospitals. The document is organized as follows. The introduction provides a brief primer on benchmarking and its application to hospitals. The next two sections discuss special considerations including the identification of normalizing factors. The presentation of metrics is preceded by a(More)

Changing the rate of airflow through a home affects the annual thermal conditioning energy. Large-scale changes to airflow rates of the housing stock can significantly alter the energy consumption of the residential energy sector. However, the complexity of existing residential energy models hampers the ability to estimate the impact of policy changes on a(More)
