Improving the Indoor Environment: Case Studies in Office and School Settings 

Five years after the renovation of their headquarters in Atlanta, GA, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) revisited the details of the renovation, the successes and the lessons learned. This session will look at the indoor air quality aspect of the project including air monitoring, high efficiency air cleaning, indoor versus outdoor contaminants using a dedicated outdoor air system, maintenance intervals, and differential static pressures which impact energy usage. 

The increasing number of office workers, increases in public awareness and concern over the health impacts of chemical exposures have led to a proliferation of IAQ complaints. Responding effectively to IAQ complaints presents a significant challenge to facility managers and occupational health professionals. In this session, an effective complaint response strategy will be examined through a real-life case study involving concerns over potential health impacts raised by lawyers employed by the Ontario government, after they detected an objectionable odour in their office space during roofing work. Techniques for developing effective response strategies to IAQ complaints will be presented. 

Minimum conditions needed to grow mold in the absence of water damage are poorly understood. A study of four unoccupied schools over the summer investigated these issues. Continuous data-logging of temperature and relative humidity allowed for a comparison of patterns associated with mold growth in one school with three mold-free schools. The schools were air-conditioned on varying HVAC schedules, providing information to support the selection of energy-efficient policies for operating unoccupied school areas over the summer. ​

Mold Analysis Data Are Not Created Equal: Standard Methods Can Help 

Practitioners interpret mold data every day, but leave the development of the data up to the lab. The analytical method used has a huge impact on the quality of the data generated. Standard methods can provide a consistent confidence in the data provided by the lab and interpretation of the data. This educational session will share information about available standard methods for analysis of mold and other microbials and the benefits from using them.​

How to Conduct Sampling for Fire-Related Particulates and Odors 

Fire-related compounds are ubiquitous in indoor/outdoor environments and can adversely impact indoor/outdoor air quality. Fire compounds can cause a wide range of exposure concerns ranging from irritation to cancer. It is reasonable to ensure that fire-affected indoor and outdoor environments are properly remediated. This discussion will focus on indoor fire remediation. The Remediation Industry Association (RIA) has developed guidelines for fire remediation and sampling. Investigation of fire-affected properties requires knowledge of investigation methods, construction, remediation, and industrial hygiene concepts, and an understanding of applicable fire-related compound sampling methods and their limitations.​

Real Time Sensor Technology: Applications By IH Students 

Real-time direct reading technology is advancing rapidly, becoming affordable, and being adopted for exposure measurement, control applications and research. This technology allows IHs to get continuous and immediate measurements from multiple sensors, can be worn by workers, and can be linked to workplace environmental controls. Presenters will discuss the use of sensor selection, performance and integration into various building control system configurations, use of real time sensors to validate the well mixed room exposure model, and an evaluation of the precision and accuracy of off-the-shelf, affordable air quality sensors.​

Current Issues in Regulatory Policy: Updates on Lead and Legionella 

HUD's Lead Safe Housing Programs in a Changing Regulatory Environment

HUD amended its Lead Safe Housing Rule for pre-1978 assisted housing in January 2017. Changes in funding levels for HUD's Lead Hazard Control Grant Programs have affected their implementation approaches and outreach and engagement strategies for stakeholders, including communities, non-profits and philanthropies, and lead and other environmental consultants and contractors. This presentation analyzes the effects of these changing regulatory environmental conditions on HUD's lead safe housing programs. 

New Cost Benefit Analysis of Policies to Prevent Childhood Lead Exposure

This presentation reviews a new cost benefit and policy analysis of ten policies that promise to greatly reduce childhood lead poisoning. The policies include addressing lead in drinking water, paint, dust, soil, food, consumer products, aviation fuel and other sources. It also examines evidence-based academic and behavioral interventions to the roughly 1.8 million children with a history of lead exposure. It draws on the most recent data available and is the first study of its kind in the US since 2000. 

New Standards and Regulation for Legionella Control in Building Water Systems

The waterborne pathogen Legionella is known for causing Legionnaire's disease. In this session the following new industrial standards and one state regulation will be reviewed and discussed: 1) New York state regulation for monitoring and treating all the cooling towers in New York for Legionella bacteria; 2) ASHRAE Standard 188 for Legionella risk management in building water systems; 3) CDC issued guideline to implement water management plan based on ASHRAE standard 188; 4) Centers for Medicare and Medicaid Services (CMS) mandates its facilities implement a water management program; and 5) National Sanitation Foundation (NSF) International will issue a building water health standard. 

Waterborne Pathogens Mysteries Solved 

Following a brief introduction to waterborne pathogens, three case studies will be reviewed during which unusual or hidden sources of waterborne pathogens amplification were identified during the risk assessment or outbreak investigation. Each case study will outline the risk assessment process and investigation plan, review the unusual sources of amplification identified, and discuss recommended control strategies.​
