EQ C4.1     CONSTRUCTION IAQ MANAGEMENT

CREDIT

APPLICABILITY: 4.1.1 applies to renovations only. 4.1.2 applies to any project involving a new HVAC system. 4.1.3 and 4.1.4 apply to all projects.

EQ C4.1         REQUIREMENTS

EQ C4.1.1         SMACNA Guidelines for Occupied Renovations

During construction, meet the recommended Design Approaches of the Sheet Metal and Air Conditioning National Contractors Association (SMACNA) IAQ Guideline for Occupied Buildings Under Construction, 2007, Chapter 3. Include the erosion and sedimentation control measures to minimize site dust during occupied renovations (4).

EQ C4.1.2         SMACNA Guidelines for Duct Cleanliness – New Ducts Only

  • Store ductwork in clean, dry conditions and keep sealed while it is stored.
  • Wipe down internal surfaces of ductwork immediately prior to installation to remove dust.
  • Seal open ends on completed ductwork and overnight work-in-progress.
  • During installation, protect ductwork waiting to be installed with surface wrapping, etc.
  • During construction, seal HVAC supply and return openings to protect them from construction dust infiltration (e.g., from drywall installation or wood floor sanding).

EQ C4.1.3         Building Flush-Out

The project team shall develop a plan, and include it in the specifications, to flush out the building with outdoor air (no return air) based on the requirements and recommendations in the specifications to remove indoor pollutants prior to occupancy. The information should also be detailed in the projects TAB and control sequence of the specifications or project manual.

The specifications at minimum must state that the maximum amount of outdoor air (the design outdoor air flow rate for maximum occupancy) must be provided during and after installation of VOC emitting materials for the maximum amount of time feasible, but not less than continuously (i.e. 24 hrs.) for seven days. It should be noted that the maximum amount of ventilation provided by an HVAC system may be limited not only by the system's capacity but also by the temperature and humidity of the outdoor air.

After substantial completion, conduct the flush out for 24 hours a day continuous ventilation for 7 days with all supply fans at their maximum rate and position. Internal temperatures are maintained at the most energy efficient level above 60°F; relative humidity is maintained no higher than 60%. Under conditions where the heating cannot be met (60°F) at that fan speed, then adjust the fan to achieve 60°F.

All air handling unit dampers are at their maximum outdoor air position during the 7-day flush out. If the 60% relative humidity level cannot be achieved with maximum outdoor air position, reduce fan speed and/or outdoor air position as needed, but extend flush-out period beyond 7 days to accomplish roughly the same amount of total air throughput that would have occurred at maximum outdoor air position.

After flush-out, replace air filters with new filters and provide two sets of additional replacement filters prior to occupancy. (2 points)

Occupied Flush-Out:

For the case where a project has fallen behind schedule, the contractor may alternatively conduct the flush-out while the building is occupied according to the requirements below or conduct air testing to identify classrooms that exceed the limits below and remedy any non-compliant rooms.

  1. Conducting Occupied Flush-Out

Conduct the flush-out for 24 hours a day with continuous ventilation for the total number of days identified in the plan with all supply fans at their maximum rate and position. Thermal comfort must be maintained during occupied hours, per the criteria in ASHRAE Standard 55. Internal temperatures must be maintained at the most energy efficient level above 60°F; relative humidity must be maintained no higher than 60% during non-occupancy hours.

All air handling unit dampers are at their maximum outdoor air position during the flush-out. If the 60% relative humidity level cannot be achieved with maximum outdoor air position, reduce fan speed and/or outdoor air position as needed, but extend flush-out period beyond the established period to accomplish roughly the same amount of total air throughput that would have occurred at maximum outdoor air position. Classrooms shall not be “baked out”. The temperature in the building space shall not be increased to attempt to bake out contaminants. (If continuous ventilation is not possible, flush-out must total the equivalent of 14 days of maximum outdoor air.)

  1. Air Testing

The square root of the total number of all classrooms must be tested for compliance with the following criteria. Any non-compliant rooms must be remedied and re-tested until they are compliant. Two additional classrooms per non-compliant classroom must also be tested in all items below in the event of non-compliance. Conduct IAQ testing using protocols consistent with the methods listed in Table EQ4-1. Use current versions of ASTM standard methods, EPA compendium methods, or ISO methods, as indicated. Laboratories that conduct the tests for chemical analysis of formaldehyde and volatile organic compounds must be accredited under ISO/IEC 17025 for the test methods they use. Demonstrate that contaminants do not exceed the concentration levels listed in Table EQ4-1.

Remedies may include spot ventilation or flush-out.

Post-Occupancy Ventilation

When the contractor is required to perform touch-up (including furniture after occupancy) work involving products with chemical emissions, provide temporary construction ventilation during application and extend the building flush-out by a minimum of 4 days after touch-up application, with 100% tempered outdoor air for 24 hours each day.(1)

EQ 4.1.4           Mold Prevention/Moisture Management

Building materials, especially gypsum wallboard, wood, porous insulation, paper, and fabric, should be kept dry to prevent the growth of mold and bacteria. Cover these materials to prevent rain damage, and if resting on the ground, use spacers to allow air to circulate between the ground and the materials. Water damaged materials shall be dried within 24 hours. Due to the possibility of mold and bacterial growth, materials susceptible to moisture that are damp or wet for more than 24 hours must be discarded. Immediately remove materials showing signs of mold and mildew, including any with moisture stains, from the site and properly dispose of them. Replace moldy materials with new, undamaged materials.

EQ C9.1     LOW RADON

CREDIT

APPLICABILITY: All projects

EQ C9.1         REQUIREMENTS

For new construction, institute radon reduction measures specifically, but not limited to: soil gas barrier, gas permeable layer, and vent pipes for fan-activated radon removal systems (should testing warrant system activation). Designs and strategies depend on the types of building foundations and other factors. See CC-1000 Soil Gas Control Systems in New Construction of Buildings by ANSI/AARST for radon reduction measures that work best for different construction types and scopes

Radon reduction measures are not deemed effective until testing verifies radon levels below 4 pCi/L. Test for radon according to MALB Protocol for Conducting Measurements of Radon and Radon Decay Products in Schools and Large Buildings.

For renovations/modernizations, perform post-renovation radon testing and make necessary mitigations should radon levels meet or exceed 4 pCi/L. Test for radon after HVAC systems are commissioned and performing as intended prior to occupancy. If mitigation is warranted, such as HVAC manipulations or sub-slab depressurization, procedures must follow RMS-LB Radon Mitigation Standards for Schools and Large Buildings as soon as possible. If radon levels are near 100 pCi/L or greater, school officials should call their State Radon Contact and consider relocating from affected rooms until the levels can be reduced. All radon testing must follow the MALB Protocol for Conducting Measurements of Radon and Radon Decay Products in Schools and Large Buildings.
