CS-2009 IEQc4.1: Low-Emitting Materials—Adhesives and Sealants

  • No reason not to earn this credit

    It shouldn’t cost you anything to earn this credit—it will just take a little work (the same is true for the related credit, IEQc4.2: Low-Emitting Materials—Paints and Coatings). Your first priority should be to specify only adhesives and sealantsA sealant has adhesive properties and is formulated primarily to fill, seal, or waterproof gaps or joints between 2 surfaces. Sealants include sealant primers and caulks. (SCAQMD Rule 1168. )Sealants are used on wood, fabric, paper, corrugated paperboard, plastic foam and other materials with tiny openings, often microscopic, that may absorb or discharge gas or fluid. that comply with the credit’s VOCA volatile organic compound (VOC) is a carbon compound that vaporizes (becomes a gas) at normal room temperatures. VOCs contribute to air pollution directly and through atmospheric photochemical reactions (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates, and ammonium carbonate) to produce secondary air pollutants, principally ozone and peroxyacetyl nitrate. limits, and enforce those specifications on the jobsite. Research low-VOC adhesives and sealants before construction begins and provide lists of acceptable materials to contractors to help ensure that the right products are used. 

    Proactive communication on the jobsite

    To observe VOC limits on the project, maintain there proactive communication between the designer, contractor, and all subcontractors who do work inside the building. Subcontractors have to be educated about the requirements, and their contracts should require that they document their compliance.

    If you make a mistake, you can still earn the credit

    Unlike some LEED credits where only a certain percentage of the materials have to comply, this credit is all-or-nothing—all paints and coatings must comply.

    However, if a non-compliant adhesive or sealant gets used by mistake, or if you need to bend the VOC limits to meet the requirements of a warranty or fire code, you can still earn the credit following the “VOC budget process.” You’ll simply have to do some calculations to show that your extra use of VOCs was offset by very low use of VOCs elsewhere. You have to meet the budget for adhesives and sealants separately from paints and coatings (for IEQc4.2), though—you’re not allowed to create a combined VOC budget covering multiple IEQc4 credits.

    Multiple benefits

    Earning this credit is a key part of a construction indoor-air-quality management plan, and will help you earn another LEED point via IEQc3.2: Construction Indoor Air Quality Management Plan—Before Occupancy, by reducing the amount of VOCs in the air.

    Using low-VOC adhesives and sealants is not only beneficial to occupants, but can improve air quality and the health of construction workers who are constantly exposed to construction pollution.

    Verify your information

    Don’t allow the use of products that merely claim to be “low VOC.” Everyone specifying and purchasing products must actually find the VOC grams per liter (g/L) information, usually on the product’s technical data sheet or material safety data sheet, and compare that number with VOC limits listed for different uses determined by the South Coast Air Quality Management District (SCAQMDSouth Coast Air Quality Management District (SCAQMD) is the air pollution control agency that regulates stationary air pollution sources in parts of southern California, including Orange County and most of Los Angeles, San Bernardino, and Riverside County.) Rule #1168 and Green Seal-36 for aerosol adhesives. Product sheets often provide the maximum g/L (like “<100 g/L”) rather than a specific amount. That’s okay as long as the maximum is under the allowable limit. 

    Only 20% of product cut sheets selected at random need to be uploaded to LEED Online to document this credit although it is best to keep all product cut sheets on file in case the credit is audited.

    Tenant limits for Core and Shell

    To get the full benefit of this credit, consider requiring VOC limits for tenant construction by incorporating either recommended compliant products, or recommending that tenants use compliant adhesives and sealants with specific VOC limits in a tenant guideline document (per SSc9: Tenant Design and Construction Guidelines).

  • FAQ's for IEQc4.1

    Is there a shortcut to the VOC budget method if you have just one product that is used minimally on a project?

    Yes, if you have just one non-compliant product, then you can balance it out with just one really good, low VOC product, as long as all your other products meet the requirement. For example, if you have two gallons of non-compliant adhesive that is 100 g/L over its required threshold, then you can balance it out with enough compliant product where you show you are at least 100g/l under the required threshold, thus balancing the VOC budget.

    How is VOC % less water determined for aerosol adhesives?

    This is usually found on a product cut sheet or MSDS1. Material safety data sheets (MSDS) are detailed, written instructions documenting a method to achieve uniformity of performance. 2. A report that manufacturers of most products are required to make available to installers and purchasers, informing them of product information on chemicals, chemical compounds, and chemical mixtures, the existence of potentially hazardous ingredients, and providing instructions for the safe handling, storage, and disposal of products. If you cannot find the information, contact the manufacturer or technical services for the product and they should be able to provide this number for you. The method for dermining this is explained in SCAQMD Method 305-9, Determination of (VOC) In Aerosol Applications.

    Do products applied to the weather barrier need to comply with VOC thresholds?

    Any applied products that have the potential to communicate their emissions to the indoor air would need to be considered for IEQc4.1, but if they have little or no potential they can be excluded. This leaves room for interpretation, so projects are encouraged to take an inclusive view of what they include. For more detail, reference LEED Interpretations 809, 811, 3716, and 5955. These are not explicitly applicable to all LEED projects and credits, but nonetheless offer the most specific guidance LEEDuser has found on this issue.

    Do grout and caulking need to be included, and if so, what is the application category?

    Yes, grout and caulking need to be included. There is no specific category for them, however. Projects have successfully used ceramic tile adhesive—VOC limit 65g/l—and Architectural Sealant—VOC limit 250 g/l—successfully, the latter being especially appropriate if you are using a product other than ceramic tiles. Since most mortars, grouts, and thinsets are largely cementitious, with inherently low VOC content, they will comply under most categories, anyway. Choose a logical category and explain it in a narrative if necessary.

    How do I determine what application my product falls under?

    SCAQMD Rule 1168 includes definitions of categories that can be helpful in determining where and how your product should be categorized to determine corresponding VOC thresholds.


    What are the adhesives and sealants to be included in the documentation?

    All adhesives and sealants used onsite within the weather barrier need to be included. This should address general construction adhesives, flooring adhesives, fire-stopping sealants, caulking, duct sealants, plumbing adhesives and cove base adhesives.

    Our project didn't use some common adhesive types, and our LEED reviewer asked about this. Are we supposed to justify not using certain adhesives in our documentation?

    No, but it might not hurt. Items commonly included in the credit are general construction adhesives, flooring adhesives, fire-stopping sealants, caulking, duct sealants, plumbing adhesives, and cove base adhesives. If your project doesn't report using one or more of these, your LEED reviewer might ask you to verify your list of documented items, to check that something wasn't inadvertently omitted. In LEEDuser's opinion, a brief narrative noting what you used and verifying that you're conscious of the fact that some common items weren't used might anticipate and answer this type of review comment.

  • construction work applying adhesivesLow-VOC adhesives benefit both the project and construction workers. Photo – ITW TACC Start researching and selecting compliant low-VOC adhesives and sealants needed for the project.


  • First check the allowable VOC levels for each product type you are using – see the summary of VOC limits in the Low-Emitting Material Limits document (see Documentation Toolkit) and then make sure the products specified do not exceed those limits.  


  • Keep VOC requirements in mind when selecting all materials used indoors. Watch out for warranty restrictions that call for use of a manufacturer-specified adhesive or sealant (which may or may not comply). 


  • Finding adhesives and sealants that are compliant with the credit requirements may sometimes take a little extra time, but is rarely a problem.

Construction Documents

Expand All

  • Make sure low-emitting requirements have been integrated in construction specifications. Products must be at or below the recommended VOC limits. VOC levels can be found on a product’s MSDS or technical data sheet and are measured in grams per liter (g/L).


  • Guidance on incorporating LEED specifications into construction documents, along with samples, is available from MasterSpec and from the Whole Building Design Guide (see Resources).


  • Identifying VOC requirements directly on the drawings as well as in the specs is a good way to remind the contractor and subcontractors of the requirements, but be careful to make sure the information is consistent between the drawings and the specs. 


  • It is best to require subcontractors to supply all LEED-required VOC information on the products they purchase at the time they are submitting products for approval. This way contractors do not wait until the end of construction to supply information, and you have the opportunity to review products for LEED compliance before products are purchased.


  • Specify compliant products by brand name whenever possible. It is best to distribute a list of acceptable products and the VOC limit chart from the LEED rating system at the contractor and subcontractor orientation meetings. 


  • Low-emitting products can be part of a more comprehensive IAQ management plan, as required for IEQc3.1: Construction Indoor Air Quality Plan—During Construction. A comprehensive IAQ plan covers all adhesives, sealants, paint, coatings, composite materials, and overall construction best practices protecting air quality.  


  • Achieving this credit can also help achieve IEQc3.2: Construction IAQ Management Plan—Before Occupancy, if your project pursues the air-testing option for this credit. Using low-VOC products improves your odds of passing the air quality tests. 


  • Only products installed within the weather barrier need to comply with VOC limits, according to the credit requirements. For adhesives and sealants that are part of the weather barrier, the LEED requirements are ambiguous, so it is best to err on the side of caution and use low-VOC products. Remember that the intention of the credit is to make sure all adhesives and sealants that have the potential to interact with indoor air are compliant. 


  • Products assembled off-site or factory-finished are exempt from this credit, because it is assumed that VOCs have off gassed before arriving at the site.


  • Using low-emitting adhesives and sealants is a no-cost measure.  


  • Some water-based adhesives and sealants that are credit-compliant may not be as strong as non-water-based adhesives and sealants. However, this is usually not a problem, as adhesive and sealants are often stronger than they need to be. 


  • Some contractors might charge a premium for implementing and documenting this credit but, in general, costs should be minor or nonexistent as more firms start incorporating these as standard best practices. 


  • Hiring construction teams with LEED experience is helpful, as is reviewing LEED requirements and responsibilities with the contractor during the bidding process. Construction teams without LEED experience can be successful with this credit, but will require more training and a closer eye on quality control to make sure compliant materials are used and that items are documented correctly.  


  • Implementing an IAQ plan and use of low-emitting materials demands accountability. It is best if subcontractors are contractually required to implement their parts of the IAQ plan. 

Construction

Expand All

  • Preparation Before Construction Begins


  • The general contractor (GC) should be oriented to all LEED-related issues, including IAQ management, low-emitting materials, environmental material tracking tools, construction waste management, and so on. A list of acceptable products for each use type, and the list of VOC limits, should be provided to aid subcontractors in product selection. 


  • The GC should hold orientation meetings with the subcontractors to review the LEED responsibilities related specifically to their trades. This exercise helps to build trust and is crucial for obtaining buy-in from all participants in the process.


  • Coordination and communication among the GC, subcontractors and design team early in the process can minimize scheduling delays and pushback from subcontractors.


  • Give the GC and subcontractors the following tools to help them track materials data for all MR and IEQ credits. (See the Documentation Toolkit for access.)

    • Materials Calculator:  This is a master tracking spreadsheet that the GC can use internally to compile product information received from the subcontractors. The spreadsheet tracks LEED values across multiple LEED MR and IEQ credits.
    • Environmental Materials Reporting Form: This is a material tracking form that helps subcontractors record the environmental values for products they purchase. This can be distributed to each trade subcontractor and submitted to the GC for filing. 
    • Low-Emitting Materials Reporting Form: This is a VOC tracking sheet that helps subcontractors record the low-emitting qualities of the products they purchase and can be distributed to each trade subcontractor and submitted to the GC for filing.
    • Low-Emitting Material Limits: These tables, found with each credit here on LEEDuser, summarize the maximum VOC limits for different types of adhesives, sealants, paints, coatings, composite wood, and flooring products. When subcontractors search for low-emitting products, they should consult these charts.

  • Research compliant, low-emitting products before construction begins. If product decisions are made after construction begins, with less time to carefully review data sheets, there is a much greater risk of using a non-compliant product. 


  • There is some room for interpretation in VOC limits, because the limits are determined by product usage and product type. For example, cove-base adhesives have a VOC limit of 50 g/L, and a multipurpose construction adhesive has a VOC limit of 70 g/L. If you use a multipurpose adhesive on a cove base, it is up to you whether to use either 50 g/L or 70 g/L as your VOC limit. Erring on the side of caution with a lower limit is generally a good idea.


  • When researching low-emitting products, double-check that the manufacturer’s information does not use misleading language. A common example is a product cut sheet that uses the term “low-emitting” without providing a specific VOC g/L value. Many cut sheets give a maximum value of, for example, VOC < 100g/L. That’s fine as long as 100 g/L meets the criteria for that product—just enter 100 g/L VOC amount for LEED documentation.


  • It is common for an MSDS to list the chemical contents of a product without giving an overall VOC g/L number. You’ll need to contact the manufacturer or check cut sheets to get the total VOC number. (See the Documentation Toolkit for a sample cut sheet.)


  • Obtain VOC levels, in writing, from the manufacturer, for the actual products used on the project—don’t rely on VOC quotes given over the phone.


  • The VOC value on an MSDS can be unreliable when several different products are listed on one sheet. Get clarification from the manufacturer on the actual VOC content of the product you are using.


  • The GC should be aware of any warranty issues that may exist if alternative adhesives or sealants are used. For example, a carpet company’s warranty may require a certain adhesive that does not meet the VOC requirements. To keep the warranty valid, use the adhesive or sealant specified in the warranty and use the VOC budget method to show a weighted average VOC compliance, or use carpet from a company that offers a low-VOC option.


  • If noncompliant materials are used onsite accidentally, or due to a warranty or other issue, you can use the VOC budget method. This method compares the total amount of VOCs (in grams per liter) used in the design case to the total amount of VOCs that would have been used if every product exactly met LEED VOC allowances. The calculation must be determined for adhesives and sealants separately from paints and coatings. For example, it won’t necessarily help your case to use low-VOC paints but also some high-VOC sealants. (See the compliance example below for adhesives and sealants.)


  • Using the VOC budget method is usually successful, but can be time-consuming to document.


  • During Construction


  • Throughout construction, the GC should collect material safety data sheets (MSDS) from subcontractors and completed VOC tracking forms for all products used onsite associated with this credit.


  • Assign someone to be responsible for inputting the subcontractors’ tracking forms into the master spreadsheet. A LEED consultant or an administrative assistant in the GC’s office may be the best choice for this role. 


  • Review subcontractor product suggestions ahead of time to avoid the purchase of inappropriate materials and eliminate the need for costly change orders.


  • Streamline documentation and research by keeping a master spreadsheet of all the items being tracked for each material across MR and IEQ credits. For example, you may need to ask the millworker for regional information for MRc5, certified wood information for MRc6, and information about adhesives installed on sight for IEQc4.1. If one spreadsheet collects all the data, it can streamline your documentation, associated research, and help with quality control. (See the Materials Calculator in the Documentation Toolkit.)


  • A master spreadsheet helps ease information collection for subcontractors, giving them a road map of exactly what types of information to collect for each product.  


  • The GC functions as the overall quality assurance provider for this credit. Responsibilities include conducting weekly reviews of subcontractor product safety data sheets and tracking forms, as well as spot checks in dumpsters to determine which products are actually being used.


  • Post signs at the construction site that reminds subcontractors to follow LEED requirements for low-VOC products. (See Documentation Toolkit for sample signs.) 


  • Schedule the application of adhesives and sealants so that offgassing does not contaminate other absorptive materials. This is required if projects are attempting IEQc3.1: Construction Indoor Air Quality Plan—During Construction. For example, do not store or install acoustic ceiling tile before flooring and wall adhesives are put down, because ceiling tiles will absorb the off-gassing of paint and floor adhesives and contaminate the air over a longer time period.


  • It is usually a good idea to do a “mini air flush” (if your project is not attempting IEQc3.2) before occupancy to help remove any lingering VOCs from the construction process. This can be as simple as putting industrial sized fans in the window and pumping in fresh air overnight or running the HVAC exhaust on high for a few days. (See IEQc3.2: Construction Indoor Air Quality Plan—Before Occupancy if the team wants to do a full flush-out for an additional LEED point.)


  • Transfer all the data collected in the master material tracking spreadsheet to the LEED Online form and upload the product cut sheets.

Francis, can you clarify? The products contain no VOCs, or you're not using any products that fall into the category addressed by this credit, i.e. adhesives and sealantsA sealant has adhesive properties and is formulated primarily to fill, seal, or waterproof gaps or joints between 2 surfaces. Sealants include sealant primers and caulks. (SCAQMD Rule 1168. )Sealants are used on wood, fabric, paper, corrugated paperboard, plastic foam and other materials with tiny openings, often microscopic, that may absorb or discharge gas or fluid.?

If the former, definitely but you have to document it as you normally would.

If the latter, which is what I think you're suggesting, I think you can earn the credit. However, I would mention this in a narrative in your LEED documentation, and it's an unusual situation so I couldn't predict exactly what GBCIThe Green Building Certification Institute (GBCI) manages Leadership in Energy and Environmental Design (LEED) building certification and professional accreditation processes. It was established in 2008 with support from the U.S. Green Building Council (USGBC). will say.

You could always pick a zero-VOC product to use a small amount of, even if you don't really need it, and that would take care of the question.

Exemplary Performance?

Project Location: United States

The BD+C Reference manual states: "This credit is not eligible for exemplary performanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. under the Innovation in Design section." However, a response from Tristan Roberts on June 4, 2010 states that if we require tenants to meet the IEQc4 requirements into the tenant guidelines, we can get an exemplary performance credit. Can we get them or not?

Walls of an underground garage typically are waterproofed against ground water, but some other barrier usually separates an unconditioned garage from the occupied, conditioned building. Besides providing thermal & moisture protection, this barrier typically blocks combustion fumes (and VOCs) from entering the occupied building.

If your parking garage is unconditioned, open to the outdoors, and separated from occupied interior space, it is NOT interior space and is, therefore, exempt from IEQc4 VOC restrictions. See LEED InterpretationLEED Interpretations are official answers to technical inquiries about implementing LEED on a project.

I have a similar question regarding technical rooms which are located underground on the same level as an underground parking. Can we assume that these spaces are exempt since they are not regularly occupied and they are separated from occupied spacesEnclosed space intended for human activities, excluding those spaces that are intended primarily for other purposes, such as storage rooms and equipment rooms, and that are only occupied occasionally and for short periods of time. Occupied spaces are further classified as regularly occupied or nonregularly occupied spaces based on the duration of the occupancy, individual or multioccupant based on the quantity of occupants, and densely or nondensely occupied spaces based on the concentration of occupants in the space.?
What about vetical ventilation shafts where ducts and pipes are located? They are separated from the occupied spaces by concrete walls as well.

According to the IEQ Space Matrix, IEQc4.1 through IEQc4.4 each applies to mechanical and electrical rooms that lie to the interior of the weatherproofing system (see (http://www.usgbc.org/resources/eq-space-type-matrix).

Likewise, ducts that carry conditioned air typically lie within the exterior weatherproofing system and within the conditioned envelope, as do pipes in many climates. As conditioned spaces, such shafts are typically included in a project’s building gross floor areaGross floor area (based on ASHRAE definition) is the sum of the floor areas of the spaces within the building, including basements, mezzanine and intermediate‐floored tiers, and penthouses wi th headroom height of 7.5 ft (2.2 meters) or greater. Measurements m ust be taken from the exterior 39 faces of exterior walls OR from the centerline of walls separating buildings, OR (for LEED CI certifying spaces) from the centerline of walls separating spaces. Excludes non‐en closed (or non‐enclosable) roofed‐over areas such as exterior covered walkways, porches, terraces or steps, roof overhangs, and similar features. Excludes air shafts, pipe trenches, and chimneys. Excludes floor area dedicated to the parking and circulation of motor vehicles. ( Note that while excluded features may not be part of the gross floor area, and therefore technically not a part of the LEED project building, they may still be required to be a part of the overall LEED project and subject to MPRs, prerequisites, and credits.) (but unconditioned air shafts, pipe trenches, and chimneys are typically excluded).

What makes basement garages different?
LI#1767 excludes parking garages that are:
. . 1. Unconditioned,
. . 2. Non-regularly-occupied,
. . 3. Open to the outdoors at all times (so not technically interior space),
. . 4. Separated from the occupied interior by impenetrable walls (weather barriers).
Since LI#1767 only addresses parking garages, I believe that this exception only applies to parking garages. If you wish to apply this exception elsewhere, you may wish to submit an inquiry to USGBC.

Finally, LEEDonline Project Information Form 2 prohibits including parking area in the “Total Project Building Gross Floor Area.” LEED treats all parking as exterior space.

The data sheet that you posted classifies the product as a “Solvent Cement for PVC Plastic Pipe.” Since the cement is intended for PVC, the manufacturer has correctly classified it as a “PVC Welding” product with a 510g/L VOCA volatile organic compound (VOC) is a carbon compound that vaporizes (becomes a gas) at normal room temperatures. VOCs contribute to air pollution directly and through atmospheric photochemical reactions (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates, and ammonium carbonate) to produce secondary air pollutants, principally ozone and peroxyacetyl nitrate. limit.

A similar product that is not intended for ABS, CPVC, or PVC would meet the definition of a “Plastic Cement Welding” product with a 250g/L VOC limit.

ABS, CPVC, & PVC are all types of plastics typically joined by “Solvent Welding.” SCAQMDSouth Coast Air Quality Management District (SCAQMD) is the air pollution control agency that regulates stationary air pollution sources in parts of southern California, including Orange County and most of Los Angeles, San Bernardino, and Riverside County. assigns a different VOC limit to the cements & solvents used to weld each of these 3 types. The “Plastic Cement Welding” category is a fourth category for cements & solvents used to weld OTHER types of plastic.

LS — I see why you are confused. Some flooring systems use a thermoplastic “welding rod” that is inserted into seams and heated to bond adjacent sheets. This is not the type of “welding” that SCAQMDSouth Coast Air Quality Management District (SCAQMD) is the air pollution control agency that regulates stationary air pollution sources in parts of southern California, including Orange County and most of Los Angeles, San Bernardino, and Riverside County. is referring to in its PVC, CPVC, ABS, & Plastic “Welding” categories.

The SCAQMD categories refer to solvents & cements like those used to join plastic piping and conduit. See the following SCAQMD-1168 definition:

SOLVENT WELDING is the softening of the surfaces of two substrates by wetting them with solvents and/or adhesives, and joining them together through a chemical and/or physical reaction(s) to form a fused union.

Also look at the “Plastic Cement Welding” definition posted above.

Patricia—A sealant is a product like caulk that, according to the SCAQMDSouth Coast Air Quality Management District (SCAQMD) is the air pollution control agency that regulates stationary air pollution sources in parts of southern California, including Orange County and most of Los Angeles, San Bernardino, and Riverside County.-1168 definition, “is any material with adhesive properties that is formulated primarily to fill, seal, or waterproof gaps or joints between two surfaces.” Does this description fit your product?

Note that a “sealant” is different from a “sealer,” which is type of coating, which, according to SCAQMD, “is applied to a surface in order to beautify, protect, or provide a barrier to such surface.”

If the manufacturer calls it a “low-solids coating,” the product is probably applied to a surface as a film. This makes it a coating, which is governed by IEQc4.2. SCAQMD-1113 defines “low-solids coating” as a coating “containing one pound or less of solids per gallon of material.”

July 31, 2009 TRB #9-09
To: SMACNAThe Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) is an international association of union contractors, in the United States, Canada, Australia, and Brazil. Members
From: Technical Resources Department
Subject: UPDATE on HVAC Duct Sealant Usage Requirements on USGBC LEED® Projects
The following bulletin is an update to TRB #4-09 issued March 27, 2009 with the Subject: HVAC Duct Sealant Usage Requirements on USGBC LEED® Projects.
In response to the following Credit Interpretation Request (CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide): “How does a project team classify duct sealants for application under EQc4.1?” the USGBC issued the following ruling: “Project teams may classify duct sealants under “Other”, as listed in the SCAQMD VOC Limits table.”
The category of “Other” in the SCAQMD VOC Limits table has a maximum limit of 420 g/l. This should allow most if not all duct sealants to be utilized on LEED® projects, and permit the proper sealing of ductwork at temperatures below 40°F (5°C).
In keeping with SMACNA’s policy on sustainability, contractors are encouraged to use products with the least environmental impact for the intended application and jobsite conditions.

Traffic Coating

Our project is a high rise office tower with 3 levels of parking. The parking levels are open air and we are applying a sealant to the roadway deck. Because it is open air does it need to be included in IEQ 4.1? It is technically inside the exterior envelope of the building but is open to the elements on 3 sides.
Thank you.

First, I would like to throw a question back to you; have you investigated roadway sealantsA sealant has adhesive properties and is formulated primarily to fill, seal, or waterproof gaps or joints between 2 surfaces.

(SCAQMD Rule 1168. )Sealants are used on wood, fabric, paper, corrugated paperboard, plastic foam and other materials with tiny openings, often microscopic, that may absorb or discharge gas or fluid. that would meet the criteria for quality and price? I like to point out the fact that the IEQ criteria are not only for the end users of the building but the overall emission of VOCA volatile organic compound (VOC) is a carbon compound that vaporizes (becomes a gas) at normal room temperatures. VOCs contribute to air pollution directly and through atmospheric photochemical reactions (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates, and ammonium carbonate) to produce secondary air pollutants, principally ozone and peroxyacetyl nitrate.'s into the environment, and more importantly, for the workers that are applying them.

That said, I would imagine that the parking lot is not inside the building envelope, as in is not an enclosed space; therefore excluded from EQc4.1 criteria.

Single ply roof membrane

In a greenroof application, if a single ply roof is use (we called it a "liner"), does it have to comply with the 450 g/L of VOCA volatile organic compound (VOC) is a carbon compound that vaporizes (becomes a gas) at normal room temperatures. VOCs contribute to air pollution directly and through atmospheric photochemical reactions (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates, and ammonium carbonate) to produce secondary air pollutants, principally ozone and peroxyacetyl nitrate. limit?

Techically, it is on top of the building on the outside. And it is a waterproofing membrane. Since the "interior of a building" is defined as everything inside the waterproofing system we consider this product does not need to be compliant with the 450 g/L limit. Are we correct?

Sealant for granite/marble

In a project we are working on they will speficy granite floors and a sealant will be needed to be applied to it.

Would architectural sealant be the best fit for this?

By grout I mean the "paste" that goes betwenn two ceramic tiles, like the one in a restroom. Would it be the same as the ceramic tile adhesive or is there any specific requirement for a grout?

Thank you Emily, I just saw it (architectural sealant and has to be a 250 g/L limit).

What about the Ceramic tile adhesive? In a project we are working on they want to use a mixture of cement, sand and water, instead of an actual adhesive. I consider this mixture excempt from VOCA volatile organic compound (VOC) is a carbon compound that vaporizes (becomes a gas) at normal room temperatures.

VOC content for concret additive (curing enhancer)

Our project has a milan wall wich has some water filtrations, a mortar made out of cement and an additive is being used to seal these filtrations.

The additive consists on a powder added to the concrete and it is used to accelerate the concrete's curing process, that's the only thin the additive does to the concrete mixture.

Since it is an additive that at the end is "fixed" in the concrete, does it have to comply with any certain VOCA volatile organic compound (VOC) is a carbon compound that vaporizes (becomes a gas) at normal room temperatures. VOCs contribute to air pollution directly and through atmospheric photochemical reactions (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates, and ammonium carbonate) to produce secondary air pollutants, principally ozone and peroxyacetyl nitrate. limits?

It is not a sealant, it just helps the concrete cure faster.

Any information will be appreciated.

John, one more question.

What about a waterproof additive? This is a powder that is mixed with the concrete mixture and gives it waterproofing properties.

It is not a coating so it has no primer or anything, like I mentioned, it is just a powder added to the concrete.

Yes, everything applied on-site inside the weather barrier needs to meet this credit. Often this type of product has zero VOCs, you just need to document it with an MSDS1. Material safety data sheets (MSDS) are detailed, written instructions documenting a method to achieve uniformity of performance. 2. A report that manufacturers of most products are required to make available to installers and purchasers, informing them of product information on chemicals, chemical compounds, and chemical mixtures, the existence of potentially hazardous ingredients, and providing instructions for the safe handling, storage, and disposal of products or manufacturer letter.

VOCs contribute to air pollution directly and through atmospheric photochemical reactions (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates, and ammonium carbonate) to produce secondary air pollutants, principally ozone and peroxyacetyl nitrate. concentration data the manufacturer gives us is in ppmParts per million. measured in a 100gr sample, is it logic to calculate a gr/kg instead of gr/l value and use it as equivalents? Since the material is not in liquid presentation, we don't know how to approach this.

Hi Emily,

Thank you for your reply. It's the same kind of product that Joanna mentioned above. You mix it with plain water, (4 liters for a 20 kilogram bag). The manufacturer already gave us a letterhead description of the product stating that no VOCA volatile organic compound (VOC) is a carbon compound that vaporizes (becomes a gas) at normal room temperatures. VOCs contribute to air pollution directly and through atmospheric photochemical reactions (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates, and ammonium carbonate) to produce secondary air pollutants, principally ozone and peroxyacetyl nitrate.'s are present in it. So I guess we should submit it that way, right?

Thanks.
