The table and equation are below Total required ventilation Continuous ventilation Section A Total ventilation – The mechanical ventilation system shall provide sufficient outdoor air to equal the total ventilation rate average, for each one‐hour period according to the above table or equation. For heat recovery ventilators (HRV) and energy recovery ventilators (ERV) the average hourly ventilation capacity must be determined in consideration of any reduction of exhaust or out outdoor air intake, or both, for defrost or other equipment cycling. Continuous ventilation - A minimum of 50 percent of the total ventilation rate, but not less than 40 cfm, shall be provided, on a continuous rate average for each one‐hour period. The portion of the mechanical ventilation system intended to be continuous may have automatic cycling controls providing the average flow rate for each hour is met.

The fan that is chose for continuous ventilation must be equal to or greater than the low cfm air rating and less than 100% greater than the continuous rate. (For instance, if the low cfm is 40 cfm, the continuous ventilation fan must not exceed 80 cfm.) Automatic controls may allow the use of a larger fan that is operated a percentage of each hour. Section D Directions - Describe the operation of the ventilation system. There should be adequate detail for plan reviewers and inspectors to verify design and installation compliance. Related trades also need adequate detail for placement of controls and proper operation of the building ventilation. If exhaust fans are used for building ventilation, describe the operation and location of any controls, indicators and legends. If an ERV or HRV is to be installed, describe how it will be installed. If it will be connected and interfaced with the air handling equipment, please describe such connections as detailed in the manufactures’ installation instructions. If the installation instructions require or recommend the equipment to be interlocked with the air handling equipment for proper operation, such interconnection shall be made and described. Section B Balanced, HRV (Heat Recovery Ventilator) or ERV (Energy Recovery Ventilator) – cfm of unit in low must not exceed continuous ventilation rating by more than 100%. Exhaust only Continuous fan rating in cfm Directions - Choose the method of ventilation, balanced or exhaust only. Balanced ventilation systems are typically HRV or ERV’s. Enter the low and high cfm amounts. Low cfm air flow must be equal to or greater than the required continuous ventilation rate and less than 100% greater than the continuous rate. (For instance, if the low cfm is 40 cfm, the ventilation fan must not exceed 80 cfm.) Automatic controls may allow the use of a larger fan that is operated a percentage of each hour.

Use this column if there is one atmospherically vented (other than fan‐assisted) gas or oil appliance per venting system or one solid fuel appliance. D. Use this column if there are multiple atmospherically vented gas or oil appliances using a common vent or if there are atmospherically vented gas or oil appliances and solid fule appliances. Table 501.4.1 PROCEDURE TO DETERMINE MAKEUP AIR QUANITY FOR EXHAUST EQUIPMENT IN DWELLINGS (Additional combustion air will be required for combustion appliances, see KAIR method for calculations) Directions ‐ In order to determine the makeup air, Table 501.4.1 must be filled out (see below). For most new installations, column A will be appropriate, however, if atmospherically vented appliances or solid fuel appliances are installed, use the appropriate column. Please note, if the makeup air quantity is negative, no additional makeup air will be required for ventilation, if the value is positive refer to Table 501.4.2 and size the opening. Transfer the cfm, size of opening and type (round, rectangular, flex or rigid) to the last line of section D. A. Use this column if there are other than fan‐assisted or atmospherically vented gas or oil appliance or if there are no combustion appliances. (Power vent and direct vent appliances may be used.) B. Use this column if there is one fan‐assisted appliance per venting system. (Appliances other than atmospherically vented appliances may also be included.)

An equivalent length of 100 feet of round smooth metal duct is assumed. Subtract 40 feet for the exterior hood and ten feet for each 90‐ degree elbow to determine the remaining length of straight duct allowable. B. If flexible duct is used, increase the duct diameter by one inch. Flexible duct shall be stretched with minimal sags. Compressed duct shall not be accepted. C. Barometric dampers are prohibited in passive makeup air openings when any atmospherically vented appliance is installed. D. Powered makeup air shall be electrically interlocked with the largest exhaust system. Explanation ‐ If no atmospheric or power vented appliances are installed, check the appropriate box, not required. If a power vented or atmospherically vented appliance installed, use IFGC Appendix E, Worksheet E‐1 (see below). Please enter size and type.

A National Pollutant Discharge Elimination System (NPDES) Construction Stormwater Permit is required for “Construction activity that results in land disturbance of equal to or greater than one (1) acre or if a project is part of a common plan of development that will ultimately disturb greater than one (1) acre,” (NPDES Permit, Section 1.2). Project Site Address: _____________________________________________________________________ Company Name: _________________________________________________________________________ *Primary Company Contact: _________________________________________________________________ *Should a site be deemed noncompliant, this individual will be notified Phone #: ____________________________ Email: ______________________________________________ If you are not covered under a NPDES Construction Stormwater Permit administered by the Minnesota Pollution Control Agency (MPCA), an erosion and sediment control plan MUST be approved as part of the residential building permit application. “Permittees must ensure a trained person will inspect the entire construction site at least once every seven (7) days during active construction and within 24 hours after a rainfall event greater than ½ inch in 24 hours,” (NPDES Permit, Section 11.2). The City of Lakeville reserves the right to request weekly inspection logs. The City of Lakeville may issue a STOP WORK ORDER; withhold building inspections; or, draw on securities/escrows to bring the site into compliance with the NPDES Construction Stormwater Permit (MN R 100001) or erosion and sediment control plan.
