Health & Safety
Under the new formula, high-performance homes & businesses will need to be ventilated at a higher rate, namely 7.5 cfm per person plus 3 cfm per 100 square feet. This means that for a tightly built 2,400-square-foot home with 3 bedrooms, the minimum airflow rate of the ventilation equipment has jumped 89%, from 54 cfm to 102 cfm.
ISO and Federal Air Change Rates for Cleanrooms. A critical factor in cleanroomdesign is controlling air-change per hour (ACH), also known as the air-change rate, or ACR. This refers to the number of times each hour that filtered outside airreplaces the existing volume in a building or chamber.
What is ISO class 5?
By comparison, an ISO class 5 cleanroom is designed to allow no more than 3,520 particles equal to or larger than 0.5 microns per cubic meter of air. This equates to aClass 100 cleanroom under the Federal Standard 209E, which allows for 100 particles (0.5 microns or larger) per cubic foot of air.
Indoor Air Quality?
Indoor Air Quality (IAQ) is the measure or measurements of the atmosphere in your dwelling or business. These measurements are assessed against the standards that The Environmental Protection Agency (EPA) has provided. Poor indoor air quality can result in asthma, headaches, poor sleep, dizziness, weakness, nausea, drowsiness, damage to liver/kidneys, and in extremely rare cases, death. Building Analyst Group, Inc. retains the tools, equipment, and expertise to perform residential and commercial testing in order to help our clients maintain clean indoor air quality.
Carbon Monoxide (CO) is a colorless, odorless gas that interferes with the delivery of oxygen through the body. CO causes headaches, dizziness, weakness, nausea, and even death. Potential sources are defective central heating furnaces, automobile exhaust, tobacco smoke, space heaters using fossil fuels, and other appliances that may use fuel in the home. The solution to Carbon Monoxide in the air is to eliminate the source.
Carbon dioxide (CO2) is exhaled by humans and pets as a natural part of the metabolic process. High levels of CO2 can cause drowsiness and headaches. ASHRAE recommends that indoor CO2 levels not exceed 700 ppm above outdoor ambient levels. The solution for high CO2 levels in the air is adding ventilation.
Volatile Organic Compounds
Volatile organic compounds (VOCs) are chemicals found in home furnishings, carpets, building materials, paints and lacquers, cleaning supplies, waxes, pesticides, moth repellents, air fresheners, and dry-cleaned clothing. VOCs evaporate into the air when these products are used or sometimes even when they are stored. Volatile organic compounds irritate the eyes, nose and throat, and cause headaches, nausea, and damage to the liver, kidneys, and central nervous system. With prolonged exposure, some VOCs can cause cancer. Solutions for high VOC levels in the air include ventilation and VOC destruction technologies. Learn More
Particulates can induce eye, nose, and throat irritation; respiratory infections, bronchitis and even lung cancer. Particulates include asthma triggers and mold. The solutions for particulates in the air include, but are not limited to, filtration and ventilation. Learn More
