A Corsi-Rosenthal Box is a highly effective DIY air cleaner made of easy to obtain materials such as HVAC filters, a box fan, cardboard, and tape
Image
Image
Equipment needed to pressure test the airtightness of walls separating the house from an attached garage
Image
Gas sensors are used for gas leak detection and carbon monoxide detection
Image
Image
Install a self-closing door with weatherstripping and thoroughly air-seal the shared house-garage walls to help keep automobile exhaust and other pollutants out of the home.
Image
Installing a garage exhaust fan is one important step in keeping auto exhaust and other pollutants out of the home
Image
Image
Mechanical exhaust is not required in this shared parking garage in a multistory multifamily building because the garage is not enclosed and can rely on natural air changes to reduce airborne contaminant concentration.
Image
Image
Right - Air-sealing the wall between the garage and the home is vital for occupant health and safety.
Image
Right - The automated ventilation system has a sensor built in switch that can detect indoor air pollution; if it senses a rise in humidity, VOCs, smoke, carbon dioxide, or small particulates, the system will turn on the nearest fan to eliminate pollution
Image
Right – This plug-in sensor detects indoor air quality issues in a home, including elevated levels of humidity, VOCs, smoke, carbon dioxide, or small particulates; if detected, the sensor can switch on the nearest exhaust fan to remove the pollutants.
Image
The air tightness of the garage-to-house air barrier can be tested with a blower door kit and two manometers
Image
The air tightness of the house-garage air barrier can be tested using a CFM50 test that is first run with the garage door to outdoors closed
Image
The air tightness of the house-garage air barrier can be tested using a CFM50 test that is run first with the garage door to outdoors closed and then with the overhead garage door to outdoors open
Image
The airflow direction is labeled on the edge of the filter to ensure it is properly oriented when installed.
Image
The edge of this 1-inch HVAC filter indicates it's dimensions, allowing proper matching of filter to air handler
Image
The green-lit panel next to the fan and light switches is an indoor air quality sensor that will automatically turn on the exhaust fan if it detects a rise in humidity or indoor air pollutants.
Image
The MERV rating, particle capture efficiencies, and pressure drops are printed on the side of this 1-inch pleated filter
Image
These garages attached to multifamily townhouses are open to the exterior, allowing for natural air changes to remove airborne contaminants from the garage.
Image
This shared parking garage in a multistory multifamily building is open to the exterior, allowing for natural air changes to control airborne contaminant concentration.
Image
To test house-to-garage airtightness, after connecting the green tubing as shown, connect the red tubing as follows: connect the input tap on channel “A” of the two-channel manometer (2CM) to the reference tap on channel “B” of the 2CM
Image
To test house-to-garage airtightness, first set up the blower door kit with the smart manometer in the blower door
Image
Two manometers are used when pressure testing the airtightness of the walls separating the house from an attached garage
Image
When moisture is trapped inside walls, mold can grow unchecked, causing damage to the walls and health impacts for the occupants.
Image
Wrong – Cars should never be left running in a closed garage. Air seal walls, install a garage fan, and inform home owners of the dangers of running a vehicle with the garage door shut
Image
Wrong – this framing material has a moisture content above 18% as shown by the moisture meter
