Baltimore City Code, Building Codes, Part XI, Section 1001.3 Functional and Performance Testing and Commissioning

Section 1001.3. Functional and Performance Testing and Commissioning 1001.3.1 Building Systems Functional and Performance Testing (FPT). 1001.3.1.1 FPT Requirements. An FPT process shall be performed for the following: a. through e. {As in IgCC} f. Building envelop systems. 1001.3.1.2 Activities Prior to Building Permit for Facilities Using FPT Process. The following activities must be completed before a permit is issued for any system requiring FPT: a. Designate FPT providers. 1. For systems that are required to comply with § 1001.3.1.1.2, FPT providers must be the owner’s qualified employees, independent commissioning (Cx) providers, or qualified designers experienced with FPT on the designated systems. 2. FPT providers must be independent of the building system design and construction function and must possess the necessary experience and testing equipment. 3. For projects less than 20,000 square feet, project team may serve as commissioning providers so long as the owner signifies approval by letter to the Code Official. b. Review of construction documents. FPT providers must review the construction documents to verify that: 1. the relevant sensor locations, devices, and control sequences are properly specified; 2. performance and testing criteria are included; and 3. equipment to be tested is accessible for testing and maintenance. 1001.3.1.3 Activities Prior to Building Occupancy for Facilities Using the FPT Process. {As in IgCC} 1001.3.1.4 Documentation. {As in IgCC} 1001.3.2 Building Project Commissioning (Cx) Process. {As in IgCC} 1001.3.2.1 Systems to be Commissioned. For buildings that exceed 10,000 ft2 (1000 m2) of gross floor area, the Cx process must be included in the design and construction of the building project. The following systems and associated controls, where included in the building project, must be commissioned: a. through h. {As in IgCC} i. Building envelop systems. 1001.3.2.2 through 1001.3.2.5 {As in IgCC} (Ord. 24-341 Section 1.)

Baltimore City Code, Building Codes, Part XI, Section 1001.4 Construction Operations and Start-Up Requirements

Section 1001.4. Construction Operations and Start-Up Requirements 1001.4.1 Erosion and Sedimation Control (ESC). {Not Adopted} 1001.4.2 IAQ Construction Management. Develop and implement an IAQ construction management plan to include the following: a. through c. {As in IgCC} b. PreK-12 schools and health-care projects. For preK-12 schools and health-care projects, after construction ends, prior to occupancy and with all interior finishes installed, a postconstruction, preoccupancy building flush-out, as described in § 1001.7.1, or a postconstruction, preoccupancy baseline IAQ monitoring, as described in § 1001.7.2, must be performed 1001.4.3 through 1001.4.5 {As in IgCC} (Ord. 24-341 Section 1.)

Baltimore City Code, Building Codes, Part XI, Section 1001.7 Postconstruction Building Flush-out and Air Monitoring {As in IgCC}

Section 1001.7. Postconstruction Building Flush-out and Air Monitoring {As in IgCC} 1001.7.1 Postconstruction, preoccupancy flush-out. {As in IgCC} 1001.7.2 Postconstruction, preoccupancy baseline IAQ monitoring. Baseline IAQ testing shall be conducted after construction ends and prior to occupancy. Testing shall be performed using protocols consistent with the USEPA Compendium of Methods for the Determination of Toxic Organic Pollutants in Ambient Air, TO- 1, TO-11, TO-17, and ASTM Standard Method D 5197. The testing must demonstrate that the contaminant maximum concentrations listed in Table 1001.7.2 3.1.5 are not exceeded in the return airstreams of the HVAC systems that serve the space intended for occupancy. If the return airstream of the HVAC system serving the space intended for occupancy cannot be separated from other spaces, then for each portion of the building served by a separate ventilation system, the testing must demonstrate that the contaminant maximum concentrations at breathing zone listed in Table 1001.7.2 3.1.5 are not exceeded in the larger of the following number of locations: (i) no fewer than one location per 25,000 ft2 (2500 m2) or (ii) in each contiguous floor area. For each sampling point where the maximum concentration limits are exceeded, conduct additional flush-out with outdoor air, and retest the specific parameters exceeded to demonstrate that the requirements are achieved. Repeat procedure twice. When retesting noncomplying building areas, take samples from the same locations as in the first test. Table 1001.7.2 Maximum Concentration of Air Pollutants relevant to IAQ Contaminant | Minimum Concentration, μg/m3 (Unless Otherwise Noted) Nonvolatile Organic Compounds Carbon monoxide (CO) | 9 ppm and no greater than 2 ppm above outdoor levels Ozone | 0.075 ppm (2 h) Particulates (PM 2.5) | 35 (2 h) Particulates (PM 10) | 150 (2 h) Volatile Organic Compounds Acetaldehyde | 140 Acrylonitrile | 5 Benzene | 60 1,3-butadiene | 20 t-butyl methyl ether (methyl-t-butyl ether) | 8000 Carbon disulfide | 800 Carbon tetrachloride | 40 Chlorobenzene | 1000 Chloroform | 300 1,4-dichlorobenzene | 800 Dichloromethane | 400 1,4-Dioxane | 3000 Ethylbenzene | 2000 Ethylene glycol | 400 Formaldehyde | 33 n-Hexane | 7000 Naphthalene | 9 Phenol | 200 4-phenylcyclohexene (4 PCH) a | 2.5 2-propanol (isopropanol) | 7000 Styrene | 900 Tetrachloroethene (tetrachloroethylene, perchloroethylene) | 35 Toluene | 300 1,1,1-trichloroethane (methyl chlorofoam) | 1000 Trichloroethene (trichloroethylene) | 600 Xylene isomers | 700 Total volatile organic compounds (TVOC) | _____ b a. This test is only required if carpets and fabrics with styrene butadiene rubber (SBR) latex backing material are installed as part of the base building systems. b. TVOC reporting must be in accordance with CDPH/EHLB/Standard Method V1.1 and must be in conjunction with the individual VOCs listed (Ord. 24-341 Section 1.)
