A green, or sustainable, building is a structure that is designed, built, renovated, operated or reused in

an ecological manner

“Meet the needs of the present without compromising the ability of future generations to meet their needs.”

‐‐UN Commission on Environment (Bruntland Commission, 1984)

WHAT IS SUSTAINABILITY?

Put less in Put less outWHATEVER

WE DO

• Natural resources

• Water

• Energy

• Virgin materials

• Air emissions

• Solid waste

• Waste water

The Basic Concept of “GREEN”

Why is the Green Building concept important to our customers?

• Impact of government requirements– Federal

– State

– City

• The public's sensitivity to the environment and indoor air quality

• Economic considerations of building green

Buildings with good overall environmental quality can reduce the rate of respiratory disease, sick building syndrome and enhance worker performance.

Adhesives Industry Contribution to Green

Requirements for LEED‐Compliant Products:

Use of materials that improve air quality: develop an IAQ plan to reduce particulates in the air during installations

Low VOC emitting products: indoor environmental quality

Recycled content: reduce impact from extraction and processing of virgin materials

Use of regional materials: reduce environmental impact from transportation

•Loading factor= 0.45 m²/m³

It simulates the situation in a common installation of a floor in a typical apartment

EMISSION CHAMBERS

The sample is uniformly mixed, weighed and applied on a glass non adsorbent surface; the test specimen is transferred into the chamber immediately after preparation.

Active air sampling was collected at 1, 3, 10 and 28 days after specimen

preparation on Tenax TA® tubes

Tenax tubes are then desorbed by a thermo‐desorber; volatile organic compounds are separated by gas‐chromatography, identified and quantified by MS detector

SCAQMD Rule 1168

Limit = 60g/l

R value

Ri = Ci / LCIi

R = sum of all Ri = sum of all ratios (Ci / LCIi) ≤ 1R calculated on emissions of the considered adhesive is lower than 1

VOC (g/L) = (Ws – Ww – Wes) / (Vm – Vw – Ves)

Ws = weight of volatile compounds, in grams

Ww = weight of water, in grams

Wes = weight of exempt compounds, in grams

Vm =volume of material, in liters

Vw = volume of water, in liters

Ves = volume of exempt compounds, in liters

DISCUSSION

TWO WATER BASED ADHESIVE FORMULATIONS:SAME COMPOSITION, DIFFERENT ORGANIC FRACTION

THE SAME APPROACH IS APPLIED TO OTHER CONSTRUCTION PRODUCTS IN ORDER TO CERTIFY THEM AS “VERY LOW VOC” IN MARKETS.

CONCLUSIONS

THIS EVALUATION CAN GUARANTEE A GOOD

ITS BENEFITS ON HUMAN HEALTH

IN OUR OPINION VOC EMISSIONS EVALUATED ACCORDING

TO ISO 16000 IS THE ONE THAT BETTER SIMULATE THE

SITUATION IN OUR HOUSES
