Step 1: Calculate the ventilation required for the building {Ans: AIRFLOW (b) = 0.35 x volume / 60 volume = 8 x (1500 + 700) = 17600 cubic ft AIRFLOW (b) = 0.35 x 17600 / 60 = 102 cfm (cubic feet/minute)}When air sealing, enclosed cavity insulation representing 15% or more of the total building shell area, OR sealing of the ducts outside the thermal envelope are recommended... {Ans: the work scope MUST include pre and post-installation blower door tests}Step 2: Calculate the ventilation required for the people {Ans: AIRFLOW (p) = 15 x occupants AIRFLOW (p) = 15 x 4 = 60 cfm (cubic feet/minute)}Step 3: Using the higher airflow requirement, convert to CFM50 {Ans: MINIMUM_CFM50 = AIRFLOW x N **where N is the LBL (Lawrence Berkley Laboratory) conversion factor - see chart on page 5. of standards MINIMUM_CFM50 = 102 x 15.4 = 1570 CFM50}MINIMUM Health & Safety Requirement (Buidling Analyst Professional) {Ans: These requirements apply to all jobs with work related to energy efficiency and/or IAQ performed by BPI accredited firms.}Whenever blower door tests are required: {Ans: the results MUST be compared to the Building Airflow Standard (BAS) to verify compliance
