(+) Adjusted Sensible Recovery Efficiency for HRVs and ERVs
(+) Attic Ventilation
Attic ventilation is an important part of an overall ventilation strategy to make homes more durable and comfortable. Without proper attic ventilation, the home's HVAC equipment must work harder to maintain the indoor comfort level. Utilizing a properly sized and installed powered attic ventilator (PAV) along with accommodations for adequate make-up air, one can ensure that the hot and humid attic air is exhausted and replaced with the fresh outdoor air.
(+) Basic Radon Facts for Consumers
According to US EPA estimates, radon gas is the number one cause of lung cancer among non-smokers and is the second leading cause of lung cancer overall. Radon is responsible for about 21,000 lung cancer deaths every year and about 2,900 of these deaths occur among people who have never smoked. This fact sheet was developed in collaboration with the US EPA and contains basic radon facts for consumers. It also outlines how to arrange for your home to be tested for this life threatening and naturally occurring radioactive gas.

(+) Proven Airtightness Essential for Energy Efficient Homes
The last three decades of home building research and development have demonstrated that airtightness is critical to improving the energy performance and durability of all homes, both new and existing. Home buyers are increasingly aware of the need to conserve energy to reduce operating costs and the impact on the environment, escalating the demand for better built homes. In addition to home buyers, government entities such as the Environmental Protection Agency (EPA) and the Department of Energy (DOE) are taking steps to encourage home builders to build tighter homes.

(+) Home Ventilating Institute (HVI) Indoor Air Quality (IAQ) Position Paper
Mechanical ventilation plays a critical role in maintaining acceptable indoor air quality in homes. In this article, the Home Ventilating Institute, the authority on residential ventilation systems, offers guidelines on how to select the right ventilation system for your home, how much air it should move and why, types of ventilation systems, and where to get more information on ventilation standards.

(+) Mold, Moisture, and Houses — Ventilation is an Effective Weapon
This guideline document provides an overview of residential mold prevention for the average consumer — the resident of today's North American housing. It provides a basic scientific explanation of mold fundamentals, findings related to problems blamed on mold, and an introduction to psychrometrics — the science of air containing moisture. That scientific base is then applied as a general guideline for making the practical decisions associated with residential design, construction, ventilation and operation for effective mold control.

(+) Low Sone Fans
Homes built in recent years are often larger and more airtight than in the past in order to keep conditioned air from escaping. These larger homes often have larger bathrooms with whirlpool baths, steam showers and other amenities to provide added comforts. As a result, many homeowners and builders have recognized the need for quiet ventilating fans. Homeowners want to enjoy a quiet, relaxing whirlpool bath without being disturbed by a loud ventilating fan. They choose a quiet model in order to fully enjoy their home investment.

(+) Ventilation Controls for Life-Styles, presented by the HVI Sales & Marketing Committee
In recent years, as new homes have become more airtight, the awareness of the need for residential mechanical ventilation has been growing more than ever. Proper ventilation is essential to removing excessive moisture, which promotes mold and mildew build-up and can deteriorate the building's structure. Ventilation is also important to help reduce the build-up of volatile organic compounds (VOCs) that affect indoor air quality (IAQ) and may cause health problems for occupants.

(+) Mold and Health Issues
Suellen W. Pirage, PhD
Over the past decade, there has been extreme media attention to issues about mold and allegedly adverse effects. Unfortunately, misinformation about mold and health effects abounds and often the public is led to believe that exposure to mold is a dangerous event. This paper presents common points of misinformation about mold and health. Scientific documentation to refute the misinformation is presented.
Mold and Health Issues
(+) Indoor Air Quality and Mold Prevention of the Building Envelope
Roger Morse and Don Acker
Microbiological organisms, such as fungi and bacteria, are important components of our ecosystem. These microorganisms break down dead material into its constituent components and as such are important participants in earth's continuing life cycle. However, if these microorganisms proliferate in buildings, they can adversely impact indoor air quality (IAQ), create hazardous health conditions for the occupants and contribute to the deterioration of building components.
