Describe Ventilation rates needted to ensure quality indoor air
Ventilation Desing: must be designed within the requirements of ASHRAE 62.1-2013.
Demand Controlled Ventilation: CO2 Levels must be under 800ppm. Exterior levels are typically in the 300-400 range.
Describe the Filtration Requirements that ensure guality indoor air
Two Filter types are used: Carbon Filters and Media Filters. Carbon removes VOC and large particles while Media filters remove smaller particles. If a project recirculates air, then it must have additional racks for carbon filters in the main air duct line. If Outdoor air is filterned in, then a MERV rating of 13 is required for the filter.
Describe the different ways to manage and remove construction pollution, outdoor contaminates, and pesticides
Protect ducts: seal off or clean ducts
Replace Filters
Manage absorptive materials
Keep dust contained to specific areas
Describe Health Effects of Lead
Health: central nervous system, cardiovascular system, reproductive system, hematological system, kidneys
Describe Health Effects of Asbestos
Health: increased risk of mesothelioma, asbestosis, lung cancer
Describe Health Effects of Polychlorinated biphenyls
negatively infect skin and impair liver functionality
Mercury
Basically death lol.
Coughing, sore throat, chest pain, increased blood pressure or heart rate, and head aches.
Identify the four ways that moisture can enter the building
Bulk Water
Capillary Water

Explain the importance of Air Flushing
it removes all of the air pollutants and particles that were in the building during occupancy. It is run at certain temps (min 59F) and humidity (60%) for a specific amount of time.
Consequences of humidity and air leakage and how it can be managed
It can cause Condensation which causes mold. Also structural issues. It is managed through a series of testing to check materials and unwanted voids. Guidlines are also set by ASHRAE 0-2005 AND NIBS 3-2012.
What are the strategies that measures and manages Air Quality and Building performance
Monitor indoor air for particle count, carbon dioxide, and ozone. The data is then saved for a minimum of three years and shared with IWBI. A plan must then be put in place to fix issues. The public must also be given access to displays that explain the conditions.
What is the importance of operable windows and how can indoor air quality be managed
They are important because it gives the end user control. It can be managed by placing monitors on a window or sending notifications to the individuals saying when to close the window.
Describe Dedicated Outdoor Air systems
This is a system that uses 100% outdoor air. It is good for controlling better air humidity. It must be approved from design drawings
Describe Displacment Ventilation Systems
Air from floor plenum and return in the ceiling plenum. Kyle you know this one.
how can air in a building be purified and sanitized?
have more carbon filters in the duct lines than are required by design, or use some kind of UV system to sanitize and breakdown air pollutants and particles
Describe how to manage combustion
Ban any elements such as fire places that cause a high amount of combustion. Limit the use of items that are necessary
Describe how to manage building products that can cause bad air quality
limit the amount of chamicals that I can’t even pronounced on page 71
Describe how to manage toxic pollutants from materials
Be careful in choosing green and clean materials that have been approved.
Describe strategies to keep a clean indoor environment
choose materials that are smooth, free of defects, dosn’t allow the collection of dust and particles. Also provide storage for items that don’t have to be out and seal locations that can be difficult to clean.
