How Air Leakage is Perceived: ‘Tight’ Building Effects, HVAC Systems and IAQ
Two case studies from northeast and southeast climates (school and government building) showing identified air leakage issues and solutions in modern “tight” buildings.
Building Diagnostics Case Study: Oak Ridge Elementary School
Newly constructed southern school with widespread IAQ issues. Diagnostic procedures, findings, recommendations, and resolutions of issues.
Reduced Greenhouse Gas Emissions via Active Energy Recovery Retrofits in Existing Schools
Describes the implementation of modern chiller technology to create heated and chilled water simultaneously for conditioning a northern school building, while improving air quality.
Moisture & Mold Basics
Includes an overview of climactic influences on building moisture, details on sources of moisture in buildings, and guidance for preventing and remediating mold.
HVAC Systems and Vapor Intrusion
An overview of HVAC components and pressure fundamentals for practitioners in the vapor intrusion industry.
The Perils of Humidification
Background on why buildings are humidified, types of humidifiers, maintenance requirements, and examples of IAQ issues resulting from humidification.
Double Duty Use 0f Heat Pump Water Heaters
Presentation of data associated with the conversion of a domestic hot water system in a basement to provide hot water and dehumidification simultaneously, with data on temperature, humidity, power, and economics.
How to Unseal an Envelope
A building science overview of air and water vapor movement through buildings and some common failure modes.
The IAQ Trap: 4 Investigations with a Common Theme
Background information on drain traps, their use and misuse, including four case studies of IAQ issues created by poor design or maintenance of drain traps.
Bad Smells and No Dog to Blame
Odor investigations conducted using IAQ fundamentals of pollutants, pressures, and pathways rather than sampling. Case studies include residential, healthcare, municipal, educational, and governmental buildings.
Hands-On Pressure Diagnostics
Background information on methods of pressure measurement and manipulation to identify airflow issues in buildings. Original presentation included one hour classroom time followed by 2-3 hours of pressure measurement and manipulation in campus buildings.
Off-Gassing and the Indoor Home Environment: What & Why, Health Impacts, Exposure Reduction
Defines off-gassing and why it happens, describes what is known about the human health effects, discusses when testing can be useful, and identifies ways to reduce exposure.
Bad Applications for Good Products
Description of several building product classes and discussion of how misuse or improper installation can lead to failures, primarily resulting in water intrusion.
Chemical and VOC Sampling
Discusses VOCs, background levels, methods of testing, and some remediation information.
Energy Savings and Environmental Control in a Historic Museum
This presentation discusses the history of a building, including historic energy and control issues. Discussion includes the issues of working in a historic structure, the envelope and HVAC remedial activities, and the energy saving results.
Advanced IAQ Diagnostic in Buildings with Suspected Disease
Looks at two specific government occupied buildings with reported elevated disease rates and explore: what was known regarding the history of each building, the rationale for the specific diagnostics that were conducted, the results obtained, and the recommendations made.
