Veneta Cucine (TV): il valore della sostenibilità

Per VENETA CUCINE la sostenibilità si declina, secondo la definizione della Tripla Bottom Line, nelle sue tre accezioni: ambientale, economica e sociale.

Un edificio, per essere definito “sostenibile”, non può considerare solo la sostenibilità ambientale, ma deve considerare anche la tutela del benessere dei suoi abitanti.

Sempre più studi dimostrano una correlazione positiva tra la salubrità degli ambienti interni e benefici quali la produttività, che aumenta con la possibilità di lavorare utilizzando la luce diurna e migliorando, l’apprendimento nelle scuole, grazie a migliori condizioni acustiche, e riduce l’assenteismo, dovuto ad ambienti più salubri.

 Ogni componente che permette di creare un ambiente sano ed “a misura d’uomo”, contribuisce a migliorare la qualità della costruzione, e sempre più, è fondamentale integrare le caratteristiche di ogni prodotto per raggiungere un obiettivo comune di edificio sostenibile. Per VENETA CUCINE la salubrità è un elemento fondamentale e non trascurabile. Per questo ritiene importante considerare l’impatto che i propri prodotti avranno negli ambienti in cui saranno installati, scegliendo così le materie prime che non hanno basse emissioni di contaminanti.

I crediti ai quali contribuisce

AREA MATERIALI E RISORSE

MR C2 - Gestione dei rifiuti da costruzione – da 1 a 2 punti

Nei confronti del prodotto in oggetto questo credito valuta il materiale di scarto e gli imballaggi in cantiere durante le fasi di posa e installazione, nella misura in cui questi vengono “deviati” dalla discarica e reintrodotti in un ciclo produttivo.

Le informazioni per il controllo dell’effettivo riciclo saranno:

•        Descrizione del materiale deviato dalla discarica

•        Luogo di riciclo

•        Quantità del materiale riciclato o deviato

•        Somma del totale dei rifiuti generati

•        Somma totale dei rifiuti deviati

•        Percentuale dei rifiuti deviati

Premesso che tali informazioni dovranno essere raccolte e calcolate dall’impresa di costruzione, è importante il ruolo svolto “a monte” da VENETA CUCINE  che utilizza un imballo riciclabile. In particolare, VENETA CUCINE potrà fornire al committente le seguenti informazioni, condizione necessaria per il conseguimento del credito MR C2:

•        In Fattura e in Bolla il peso netto e lordo del materiale trasportato (si ricava il peso dell’imballo per differenza);

•        Tipologia del materiale per l’imballo.

 MR C4 - Contenuto di riciclato – da 1 a 2 punti

Questo credito valorizza il riutilizzo di scarti provenienti da processi produttivi o materiali che finito il loro ciclo di vita finirebbero in discarica. Il riferimento per la definizione di contenuto di riciclato è la norma ISO 14021, che specifica:

Contenuto di riciclato Post-Consumo: è la quantità totale per unità di peso che deriva da prodotti precedentemente utilizzati dai consumatori, quali famiglie o spazi commerciali, industriali e istituzionali nel loro ruolo di utilizzatori finali del prodotto, che non può più essere utilizzato per il suo scopo (Esempi: contenitori in acciaio o allumino, bottiglie in plastica o vetro, asfalto dai parcheggi, gesso dalle pareti in cartongesso ecc.).

Contenuto di riciclato Pre-Consumo (Post-Produzione): è la quantità totale per unità di peso che deriva da fonti industriali esterne perché materiale deviato dal flusso dei rifiuti durante il processo di fabbricazione (N.B. non comprende il riciclo dei materiali di scarto effettuato in sito e non comprende i materiali derivati dalla rilavorazione, rigranulazione oppure ritagli generati in un processo e in grado di essere riutilizzati all’interno dello stesso). Alcuni esempi sono: la segatura usata nelle tavole MDF, le scorie degli altiforni utilizzate negli isolanti in lana minerale, la cenere volatile di carbone usata nei mix di calcestruzzo.

Il quantitativo dei singoli componenti è variabile da commessa a commessa, pertanto sarà calcolato l’esatto quantitativo complessivo di percentuale di contenuto di riciclato relativo all’assemblato al momento della formulazione della singola commessa grazie ad un tool appositamente creato.

Per maggiori informazioni contattare l’ufficio tecnico.

AREA QUALITA’ DELL’AMBIENTE INTERNO

QI C4.4 - Materiali Basso Emissivi –. Prodotti in legno composito e fibre vegetali

Il requisito di questo credito richiede che nei compositi di legno non siano utilizzate resine con aggiunta di urea formaldeide. L’attenzione è quindi sulle colle utilizzate per incollare tra loro i pannelli dei diversi strati.

Su richiesta, VENETA CUCINE può realizzare modelli che sono conformi a quanto richiesto dal presente credito grazie ad una preselezione dei propri fornitori.

Sebbene QualityNet ritenga che il prodotto esaminato possa contribuire a una certificazione LEED, si ricorda che, a livello mondiale,  unicamente GBCI (Green Building Certification Institute) può attribuire i punteggi ed emettere un  certificato LEED. Rammentando che LEED certifica l’edificio e non i materiali, Qualitynet non esprime alcuna garanzia sul conseguimento del punteggio.

POSSIBILI ULTERIORI SVILUPPI

Altri crediti che potrebbero riguardare il sistema cucina

Oltre ai crediti a cui VENETA CUCINE già può contribuire e che sono stati verificati, di seguito della richiesta di commesse specifiche, di seguito si riporta una sintesi dei crediti che potrebbero essere ulteriormente sviluppati (si riporta il testo originale di finalità e requisito).

LEED V 2009

MR Credit 5: Regional Material

Intent

To increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impacts resulting from transportation.

Requirements

Use building materials or products that have been extracted, harvested or recovered, as well as manufactured, within a specified distance of the project site for a minimum of 10% or 20%, based on cost, of the total materials value. If only a fraction of a product or material is extracted, harvested, or recovered and manufactured locally, then only that percentage (by weight) must contribute to the regional value. The minimum percentage regional materials for each point threshold is as follows:

Regional Materials Points
10% 1
20% 2

OPTION 1

All building materials or products have been extracted, harvested or recovered, as well as manufactured within a 500 mile (800 kilometer) radius of the project site.

OR

OPTION 2

Building materials or products shipped by rail or water have been extracted, harvested or recovered, as well as manufactured within a 500 mile (800 kilometer) total travel distance of the project site using a weighted average determined through the following formula:

(Distance by rail/3) + (Distance by inland waterway/2) + (Distance by sea/15) + (Distance by all other means) ? 500 miles [800 kilometers]

Mechanical, electrical and plumbing components, and specialty items such as elevators and equipment cannot be included in all calculations. Include only materials permanently installed in the project. Furniture may be included if it is included consistently in MR Credit 3: Materials Reuse through MR Credit 7: Certified Wood.

MR Credit 7: Certified Wood

Intent

To encourage environmentally responsible forest management.

Requirements

Use a minimum of 50% (based on cost) of wood-based materials and products that are certified in accordance with the Forest Stewardship Council’s principles and criteria, for wood building components. These components include at a minimum, structural framing and general dimensional framing, flooring, sub-flooring, wood doors and finishes.

Include only materials permanently installed in the project. Wood products purchased for temporary use on the project (e.g., formwork, bracing, scaffolding, sidewalk protection, and guard rails) may be included in the calculation at the project team’s discretion. If any such materials are included, all such materials must be included in the calculation. If such materials are purchased for use on multiple projects, the applicant may include these materials for only one project, at its discretion. Furniture may be included if it is included consistently in MR Credits 3. Materials Reuse, through MR Credit 7: Certified Wood.
