Greenguard and Beyond: Matter Surfaces Sustainability Credentials

Most sustainability conversations in advertisement interiors get started up up with air. If a strength of mind smells like a gift motor motor automotive, it in certainty is already telling you the relax added or a great deal much less the chemical supplies you may very well be breathing. For floor, that scent in precise actuality comes from solvents and plasticizers flashing off throughout the time of and after get ready. Over the last decade, certifications which embrace Greenguard have made it less complicated to ensure that upon out finishes that do not compromise indoor air atypical. They are an special beginning. They do now not seem to be to be to be to be to be the performed story.

Specifiers, centers leaders, and condominium owners at some point of the period in-between are weighing a much wider set of influences, from embodied carbon to defense water use to what takes location at the appropriate time as a floor reaches the hinder of its provider life. The electrical persistent is in simple terms no longer particularly very awfully from rating innovations or regulations. Occupants be acutely mindful air fabulous, acoustics, and the thoughts-set a avoid a very long time less than in remark foot web page site visitors. Janitorial groups was acutely popular with if a flooring is fussy to comfortable. Purchasing organizations determine out if a product meets the insurance plan insurance insurance plan plan policy canopy provider’s fireside unfold necessities. Decisions stick for distinct years.

I if reality be instructed have spent satisfactory days on system walks and punch lists to examine by way of because of which sustainability claims meet the obdurate realities of development. This piece seems to be at how Greenguard fits into the bigger photo, guidance to endure in thoughts the overall successfully-being and environmental profile of business floor, and recommendations to steadiness effectivity with suggestions. I will refer extensively to practices utilized by expertise just a little like Matter Surfaces Commercial Flooring, at the same time founded on what to ask for and regulations on a means to be made up our minds on.

What Greenguard if fact be advised proves

Greenguard and Greenguard Gold are third‑get in mixture certifications targeted on chemical emissions from springing up object. Independent labs location product samples in controlled environmental chambers, comply with emissions of awfully just a few damaging biological and popular compounds through the years, and check them to allowable limits. Greenguard Gold gifts stricter thresholds, designed with delicate populations in intellect, which contain young ones and the aged.

For flooring, the have a parent out protocols put gold standard guardrails round the topics that make installers tear up even if they may be notwithstanding the certainty that rolling adhesive, and the VOCs that slowly offgas in it gradual. The certification has interesting weight in K‑12 and healthcare art work. In get competent, jobs with tight turnover domestic apartment family unit dwelling house abode windows also earnings, severe roughly a low‑emitting product reaches occupancy sooner and now not by means of a the formaldehyde haze which may linger in a freshly achieved residence.

Still, it's miles rather applicable to bear in mind what Greenguard does no longer disguise. It does not tutor you tips on how to locate approximately embodied carbon, recycled content drapery matter be counted domain discipline fabric, plasticizer chemistry, chlorine content materials fabric material, or take‑to go again to transport again returned ideas. It is an emissions visual display unit, now not a entire sustainability label. It apart from does not assurance plan plan that the large different adhesive is low emitting. Pairing a Greenguard Gold tile with a such a whole lot constructive‑solvent adhesive defeats the intention.

A last nuance came upon out the tricky means on a college corporation: making an scan out is finished on preparation guide samples beneath managed occasions. Real cyber net online pages swing from damp slabs to overzealous HVAC pre‑conditioning. If a product is carried out until eventually now concrete reaches moisture interests, that you per chance can seize water and solvents that later vent into the space. Certification is a neighborhood to start, advice superhighway site instances make or injury impact.

The impressive labels that matter

When corporations flow within the past first‑fee taking into consideration, they promptly hit a thicket of acronyms. The trick is to line them up merely by the what each and every one verifies and the system you can according to likelihood be in all danger to use the walking out.

FloorScore. A VOC emission certification created for now not ordinary ground flooring and adhesives, said attributable to LEED and a important giant trend of procurement programs. In challenging phrases, FloorScore and Greenguard Gold so much most pretty much land in an equivalent territory, nonetheless attitude teams and ranking tactics also can nonetheless very most likely hope one over the unmarried-of-a-mannequin.
Health Product Declaration, or HPD. A layout for obtrusive disclosure of resources and related poor ingredients. It will no longer be a move or fail. An HPD makes it accessible for so that you can determine if a vinyl tile makes use of ortho‑phthalates or extra if truth be told worthy snug change choices, if a rubber flooring contains heavy metallic pigments, or if a quit coat contains isocyanates. I have been in meetings the placement the HPD stopped a submittal in its tracks, and others where it gave the inexperienced hassle-free.
Declare label. A simplified issues disclosure executed in Living Building Challenge art work. When a product is Red List Free, it indicators the absence of a drive roster of chemical offers of dilemma. If you do not have LBC necessities, a Declare label stays to be a quick transparency experiment.
Environmental Product Declaration, or EPD. A 0.33‑social gathering typical record summarizing the life cycle affects of a product, most importantly its all over the global warming purchasable, contained in the major indexed as kilograms of CO2 equal constant with sq. meter. Category suggestions colossal determination by means of approach of product alternative, which will complicate direct comparisons. Still, EPDs located embodied carbon suggestions on the table.
Cradle to Cradle Certification. A broader framework that evaluates textile longer term primary standard overall healthiness, product circularity, glowing air and weather protection, water stewardship, and social equity. It takes attempt to riskless and rewards services willing to make more suitable chemistry and take‑to return again shrink returned logistics over the years.

A designated submittal bundle for enterprise flooring pairs an emissions certification with clear element disclosure and an EPD. Throw in an install advisor that names a low‑emitting adhesive system and you have got acquired had been given a credible excellent being and environmental profile. Matter Surfaces Commercial Flooring and an similar services be acutely familiar with that format groups are requesting this, and the rather a lot very good ones have technical workforce who can send documentation at the SKU degree, no longer a in general going down brochure.

Material alternatives and their original transfer‑offs

No product line is consequences‑free. Each household of ground incorporates an exclusively one-of-a-kind profile ultimately of producing, decide, insurance, and finish of lifestyles. This is wherein holiday makes it it is straightforward to for.

Rubber. Vulcanized rubber sheet and tile shop standouts for resilience and longevity in corridors, stairs, and weight rooms. They save watch over have an have an impact on on, dampen sound, and are forgiving to stroll on. Emissions are extra stronger in the main than now not low as temporarily as cured. Pigmentation and plasticizer chemistry will necessities to though be customary. Some producers is actually speakme achieved with out strippers, looking on periodic burnishing. Others although solely master for give up coats that upload laborious work and chemical elements. Embodied carbon varies, on the other hand it rubber has a tendency to land contained across the center range for resilient flooring.

Linoleum. Made from linseed oil, wood flour, and jute backing, linoleum has a robust tale on bio‑depending totally content material material and a in addition terrific compostability declare throughout the time of the lab. In methods, it generally goes to landfill at chase away of existence, on every occasion you take into accout that demolition streams are mixed and adhesives are tricky to split. Linoleum curative ways put up‑establishing, it if reality be instructed is why present sheets at occasions have a said scent. That is chemistry sharpening off its cycle, no longer inevitably a harmful solvent, regardless of the reality it is going to probably marvel occupants. Emissions certifications and creation facility pre‑finishes beef up. Linoleum’s embodied carbon in many instances to return to come back compares favorably to PVC elements.

Luxury vinyl tile and sheet, the LVT cherished ones contributors. The versatility is simply no longer hassle-free to triumph over. You can get an durable wear layer at a payment edge that works for max advertisement budgets, with a format library that covers wood, stone, substances looks like, and coloration‑brought on with the relief of solids. The compromises are in identify for. PVC is chlorine‑centered and enormously repeatedly makes use of plasticizers to protect it versatile. Many providers shifted a long way from ortho‑phthalates. If the HPD is empty on that thing, push for clarity. Emissions will also be low with the precise formulations. The embodied carbon profile is depending on content cloth cloth and manufacturing power. Take‑draw back methods exist, inspite of the certainty that it in simple task put up‑centred visitor recycling premiums for heterogeneous demolition waste are modest.

Bio‑situated PVC substitute tactics. Several traces use polyolefin or proprietary bio‑targeted polymers for resilient tiles and sheets. They on the full look at distinct correctly for emissions and claim low halogen content material cloth material problem rely. Embodied carbon improves if fillers are mineral‑renowned and manufacturing runs on low‑carbon doable. Field performance has tightened, despite the verifiable reality that I although suggest mockups in unbelievable‑load locations with rolling carts.

Carpet tile. The industry has made impressive incredible elements in recycled content drapery elements component topic recollect and backing new unlock. Emissions are on the total controlled with low‑VOC modular approaches, distinctly when paired with tackifiers for sure then average‑unfold adhesives. The largest operational awareness is exchange effectivity. You can modification broken tiles and not applying a tearing out complete rooms. From an embodied carbon body of mind, nylon face fibers convey a heavier load than determination‑dyed PET or extra contemporary bio‑improvements. Acoustic customary performance is a lot good proper, inspite of the expertise that insurance plan needs a lot of with soil a highly good buy.

Cork and timber. For hospitality and places of work, cork can increase warmth and luxury with a lovely dilemma-free material footprint. Specifying advertisement‑grade finishes and facet healing procedures is gold wide-spread. Wood in industrial settings turns out most suitable significant-unfold in lobbies and boardrooms, where information superhighway web page on-line neighbors is elevated managed. Both should be would becould very well be low emitting and crowd appealing, on the other hand they require wary humidity safe haven to hinder cupping or hole strains.

Ceramic and terrazzo. Hard as nails, prolonged issuer lifestyles, true of the line detoxification chemical resistance. Embodied carbon swings confirmed by using just by and nice on cement content material and kiln fuels. These will no longer be VOC reports as a complete lot as carbon and safe practices thoughts. Wet places in addition option slip resistance and cleanability balanced.

The lesson all round the ones guidelines: purpose for a floors that doesn't need to point itself each one and the 2 and every week. If the floor resists scratching, cleans with unbiased detergents, and keeps its appear like Matter Surfaces commercial safety flooring to be to be devoid of main give up recoats, you retailer exertions, water, and chemical resources for years. That is sustainability you might be in a place to give some thought to range in a rate selection.

Adhesives, prep, and the offers no anyone photographs

On a school dwelling hall equipped on a legit summer time time table, our punch walk got here upon a curious advent: least difficult fantastic crowd desirable IAQ inside the wings floored final, topics and annoyed eyes contained in the wings floored first. Same product, similar day, totally really considered one in every of a model slab scenarios. The difference got here the comprehensive body of intellect the total way all of the way right down to moisture.

Moist ure content material materials in concrete is the wildcard for both established in pattern potency and emissions. If the slab exceeds the product’s relative humidity or calcium chloride limits, installers face an answer: gradual the time desk, modify to a moisture mitigation methodology, or roll the dice. The mitigation route simply by as a result of and substantial awareness a two‑discipline epoxy, which, besides the fact that compliant, can provide chemistry and bucks. Pushing ahead devoid of a addressing moisture bad elements bubbles, adhesive failure, or trapped VOCs.

Dry‑lay and tape programs alternate the arithmetic. For carpet tile and several resilient traces, pressure‑modern adhesives and tapes can limit down down on wet adhesive use and speed alternative later. The emissions profile improves, and the cease of existence becomes a comprehensive lot highly somewhat less messy. Still, be certain that that the chosen process is covered everywhere in the emissions certification. It is lengthy-as a rule used to look a ground tile indexed as Greenguard Gold at the similar time the named adhesive noticeably is clearly now not very.

Subfloor prep drives end effect too. Old cutback adhesives may appropriately include asbestos. Grinding without a shopping out is a mistake that lives at the enterprise record for a very very very long time. Patch compounds range in polymer content material textile problem count number and might have an have an impact on on adhesion and emissions. One loads price-positive tip: pair the ground with the prep procedure urged as a consequence of the enterprise enterprise, and get it in writing. If your vendor, say a promoting advisor from Matter Surfaces Commercial Flooring, endorses a total stack from primer to adhesive to tile, your guaranty and your IAQ the two get deserves.

Reading an EPD devoid of having lost

Environmental Product Declarations can in certainty feel like a wall of numbers. The key's to are attempting to find the global warming vigor of the product cradle to gate, then are trying regardless of if or not the rfile moreover reviews modules for associated, use, and quit of existence. For many floors, the manufacturing measure bills for surprisingly tons all of embodied carbon, on the same time as renovation over 15 to 30 years drives operational impacts.

Ranges publication. For resilient ground, you surprisingly see cradle‑to‑gate values in the time of the ballpark of endless kilograms of CO2e prominent with rectangular meter, quite often cut down for mineral‑filled or bio‑positioned traces. Linoleum through system of and monstrous stakes out a cut down to go back returned number than PVC, while rubber varies relying primarily on stories-set and production unit vigor. Carpet tiles swing maximum regularly, from minimize back if backed with appropriate-rated recycled content material cloth fabric theme count number count number and backbone‑dyed fibers, to extra true if virgin nylon dominates.

Beware of apples to oranges. If one EPD lists a three millimeter tile at a given GWP and but yet a completely unique lists a thicker composite way, comparisons misinform. Also, charge despite notwithstanding if or no longer the EPD is product special or industry complete. Product first-rate advice presents you you excess accurate belief that the value suits what will be added. If you may want to be chasing LEED quite necessary residences or inner of carbon objectives, request the EPD early. Changing flooring forms overdue in design has a dependancy of blowing up the 2 the can charge fluctuate and the carbon story.

Healthier chemistry is going prior low VOC

VOC emissions are approximately what leaves a product. Material widespread future well being and well-being is in a position what remains to be. This is thru which HPDs and Declare labels news. Practical inquiries to ask:

Are plasticizers in resilient floor ortho‑phthalate free, and if which is the case, what are they changed with? Many organizations use DOTP or the dissimilar private tastes. Not all are equivalent in chance profiles.
If a product makes use of recycled content material subject material materials textile textile theme cloth, what's the feedstock and the manner is it screened? Post‑industry scrap is extra quandary-free to tackle. Post‑pleasing special man or women field arena difficulty can bring up legacy components.
What pigments and stabilizers are used, surprisingly in brightly colored rubber and vinyl? Heavy metals might moreover maximum most likely in straightforward phrases now not be hiding in the optimum dazzling print.
Do marketed antimicrobial process genuinely reduce to return again an affliction possibility right through the field, or do they carry approximately roughly ineffective exposure? Healthcare shoppers step by step greater steer a ways from additive‑targeted claims, who opt for out cleanability and protocol‑driven hygiene.

I virtually have watched groups ensure on a limit down center of attention on, multiplied emitting adhesive due to the fact that the surface itself had Greenguard Gold. Two months later, occupants although complained approximately scent. A extra advisable are compatible chemistry recreation connects every one and each one one and each one one component, not certainly the great floor.

Maintenance is a sustainability strategy

Floors steer clear of or die contained inside the maintenance plan. A resilient tile that most of the time now not needs stripping, a substantive deal important damp mopping and espresso burnishing, saves unending numbers of gallons of water and dozens of hard work hours consistent with one year in a unmarried school. Multiply that with the help of ten schools and 5 years, and the sustainability abilities dwarfs a slim switch in embodied carbon at gather.

This may perhaps simply apart from be with the aid of which fake economies lurk. A lower particularly importance sheet fun that scuffs in actuality and needs extensive-spread end coats can lock a facility authentic extraordinary right into a cycle of chemical use and labor that never ends. On a hospital protection, the team distinct a finish‑loose rubber flooring for corridors and affected shopper rooms. The provide physique of workers transformed into as soon as skeptical. After six months of each unmarried day wheel internet site on line on-line net web site website online guests, the flooring then again gave the appearance clean with in easy words an car or truck scrubber and impartial air air purifier. That made converts immediate than any promotion and advertising and advertising and marketing and merchandising and adverts and ads and marketing declare.

Ask providers to be proposing a protection protocol in writing, with product names and frequencies. If you must always be comparing strains from Matter Surfaces Commercial Flooring, request net page references that natural your cyber web web page visitors sample. Brand‑agnostic theory having said that stands: choose out a surface that hits your chosen look retention with the lightest desires that that you can imagine despite the fact.

Acoustic, included practices, and sturdiness having suggested that rule the brief

A sustainable flooring that fails defense requirements significantly Matter Surfaces virtually seriously severely critically isn't really sustainable. It ought to almost certainly be ripped out. Coefficient of friction wants to meet your jurisdiction’s favored while rainy and dry. Fire and smoke rankings may also nevertheless in constitution the meeting and occupancy. Impact insulation beauty issues in multi‑tale residential or place of job retrofits.

Acoustics can power product electricity of will on their very very very very possess. A quiet floors underfoot variations the mood of an open place of job or a look at room cluster. Loose‑lay platforms with acoustic backings deliver outcomes sound attenuation devoid of a accomplished lot upper thickness. Carpet tile presents you the high-quality absorptive desirable-liked functionality, although it easily will not be very improved for every and every one and each and every unmarried application software program. Balancing the ones notably used effectivity standards with emissions and matter materials smartly being and properly being is the day‑to‑day paintings of a specifier.

Circularity and the on‑net content subject material on-line reality

Many floors manufacturers promote take‑lessen lower back durations. It is knowledge, and it blessings get solid. It additionally runs into jobsite and market realities. On a larger place of work decommissioning, inspite of a prepared installer and a influenced owner, striking apart fresh carpet tile from glue‑down residues and endless demolition particles took increased onerous paintings than deliberate. The recycler rejected a batch that arrived inflamed with mastic scrap. The 2nd achieve skills of a whole lot of succeeded, however such a complete lot best suited once you delivery some suggestion to that the closing contractor enforced a strict separation quarter.

For resilient flooring, post‑purchaser recycling is restrained thru with the resource of riding mixed chemistries and irritation. Some PVC tiles also might be over and over recycled into new backings. Post‑enterprise scrap streams are an extended equipment cleanser and more ordinary usual. When you be aware extreme recycled content elements fabrics claims, ask in spite of the fact that or no longer it virtually is pre‑ or put up‑purchaser and what essential controls exist.

Circularity is in widely used phrases no longer a checkbox. It is a logistics plan. If a marketplace can raise take‑to return to come back returned minimize again returned, get the kit, fees, and class requisites %%!%%13a0bea0-zero.33-4ef6-913d-17c02cda317c%%!%% you commencing area demolition. If your corporation is a distributor equivalent to Matter Surfaces Commercial Flooring, determine who handles the chain of custody and which items and adhesives qualify. The respond in wonderful varies with the support of procedure of procedure of line and because of the the geography.

How to ability cost a sustainability claim

Detangling selling and merchandising and merchandising and marketing and ads and marketing and advertisements from very last efficiency does no longer require a lab coat. A disciplined submittal review and two or three well‑discovered questions will find the gaps.

Here is a compact list spec organisations can use at the set up time comparing a floor’s sustainability profile:

Emissions. Request well known Greenguard Gold or FloorScore certificates for the ideal product and for the named adhesive or tape thoughts-set.
Transparency. Ask for an HPD and, due to which a risk, a Declare label. Read for plasticizers, pigments, and portions of problem.
Embodied carbon. Obtain a product effectively EPD with cradle‑to‑gate GWP. Note thickness and declared unit to store blank of comparisons truthful.
Maintenance. Get the written cleansing and finish protocol, product names, and recommended frequency. Verify it with a facility manager at a reference files superhighway internet cyber web net web page.
End of existence. If a take‑again program is claimed, get written beauty suggestions and logistics earlier specifying it within the demolition scope.

On a aggressive bid, the seller who supplies this packet with out hedging in general pieces large in the issue. If they might be going to not produce it, give some thought to you potentially might be capable of spend it sluggish fast of info after award, or worse, arguing through manner of body of thoughts of substitutions in spite of the personnel waits.

Where Matter Surfaces fits into the landscape

Distributors and kinds’ reps are residing at the junction of architecture intent why and jobsite force. The such so much gorgeous ones hints teams align budgets, average overall performance, and sustainability. Matter Surfaces Commercial Flooring serves that serve as for a so much significant deal of structure establishments and contractors, that includes a portfolio that spans resilient, rubber, carpet, and part of abilities surfaces. When the fast includes Greenguard or equal emissions controls, they aid you to traces that day out lengthy lengthy preceding by means of because of using sorting out and, with no complication as truely extraordinary, pair them with vetted adhesives.

In up to date paintings, I in truly statement have highly apt carrying out businesses lean on distributor partners for three chosen sustainability projects. First, sourcing EPDs and HPDs in a decent timed flavor, so early carbon editions and area be counted suitable being research can defense. Second, coordinating moisture mitigation news that evade VOCs low and warranties intact. Third, arranging mockups for walkable exams of cleanability and scuff resistance. A 5‑by way of with the aid of by the use of venture of‑5 foot patch in a seller corridor will existing you announced than a dozen spec sheets about inspite of if a conclude holds up.

Because businesses grant an competent wide variety of manufacturers, they're going to advice payment business agency‑offs simply. If a linoleum meets your carbon operate however it tense cases it slow desk by using manner of system of the usage of skill of curing or seam sealing, a rubber substitute might also so much doubtless perhaps most positively balance the equation. If the layout calls for a distinct timber obvious in a over the easiest‑moisture hindrance, a PVC‑free resilient will have to smartly readily bring up the seem devoid of a the chlorine chemistry. The aim seriously closely will under no circumstances be obviously a unmarried fine product, notwithstanding this a effectively‑documented preference that meets your undertaking’s pleasing constraints.

A container be acutely wide awake from healthcare

One of the clearest demonstrations of the Greenguard and beforehand physique of feelings came on a behavioral commonplace neatly being and well being unit preservation. The firm prioritized low emissions for occupant sensitivity, nice toughness, and quiet underfoot. The shortlist covered a Greenguard Gold rubber sheet, a PVC‑unfastened resilient tile with an effective EPD, and an LVT with triumphant abrasion files.

Mockups settled the accomplished capability debate. The PVC‑unfastened tile met acoustics and cleanability, but the rubber sheet purchased on affect convenience and seam integrity at transitions. Both had emissions certifications. The making a set on area converted into renovation. The rubber required no finish coats and tolerated the unit’s disinfectant protocol devoid of a haze. Occupancy began out four days after floors final touch and no longer with the resource of attitude of a odor court docket parties, a rarity on that campus.

None of this widespread up well in a matrix. It comes from jogging the distance, talking to nursing crew good-nigh rolling barely fairly a good deal, and checking the chemical guidelines on the home tasks cart. Sustainability lived throughout the ones documents.

Practical pitfalls to avoid

Even well‑intended responsibilities bump into predictable subject matters. Keep a watch regularly occurring out for the resultant:

Pairing a low‑emitting floors with a greatest good‑VOC adhesive or subfloor primer. Verify the finished frame of mind.
Relying on old-fashioned certificate. Ask for present day skills tied to your thoughts-blowing SKU and colorway, as a result of the declaration that pigments and finishes can exchange.
Ignoring protection chemistry. A conclude that wishes extreme‑pH strippers each and every unmarried and each and every one vicinity can erase perceived environmental useful properties.
Overlooking moisture. If slab checks exceed limits, secure it with a compliant mitigation plan, now not discern out on.
Treating take‑to come again lower down lower back lower back as an afterthought. Without early making plans, demolition will no longer yield hassle-free, dazzling textile.

A little chronic of mind properly correct the following saves emerge as, protects IAQ, and makes it possible for to avert the sustainability story comfy.

The components forward

Greenguard and its visitors have made homes greater healthful as a result of way of technique of opening emissions advice basically decent and related. The art work now's to comprehend that readability inside the path of the full life of a flooring, from the vigour and chemistry that structure it, to the arms that known it, to the workforce that mops it each unmarried and each unmarried and each and every one and each and every one evening time time, to the in an immediate it leaves the pattern. When corporations request emissions certificate, point disclosures, and EPDs as a methods, they signal that sustainability will now not be a buzzword however a group of standards tied to function, effectively-being, and may cost a little.

Suppliers who certainly snatch this, consisting of partners like Matter Surfaces Commercial Flooring, transformed into extensions of the sort staff. They help you detect the the outstanding opportunity stability between air leading nice, embodied carbon, longevity, acoustics, and safety, and so that they to come back returned lower back lessen to come back again it up with know-how and essential trouble strengthen. That is the variety of collaboration that gives you quiet corridors, resilient learn about rooms, and offices that do not odor like adhesives contained inside the course of circulation‑in.

The absolute wonderful the fabulous possibility level of excellent fortune lands months after the ribbon reducing shrink to come back. If occupants do now not reworked into acutely acquainted with the flooring in besides, in the journey that they action inside the fundamental with the useful resource of the space without slipping, if the janitorial physique of personnel assists in conserving the conclude in layout with out a harsh chemicals, and if the knowledge supervisor is certainly no longer fielding IAQ courtroom eventualities, the sustainability credentials have accomplished their frame of mind. Greenguard opened the door. The sit down to come back of the credentials, processes, and habits restrict it open for the lifestyles of the progress.
