ECOSPECIFIER LIFE-CYCLE ASSESSMENT

INTEGRATED DESIGN AND POLICY ISSUES

Although daylighting can enhance indoor environments and reduce artificial lighting energy, it can also generate significant nuisance glare. Shading devices enable occupants of offices and homes to reduce glare by controlling direct sunlight on internal surfaces. This also reduces eyestrain and discomfort that result from glare.

An important factor in reducing glare is reducing contrast levels. Fabrics and screens, such as some of the colours in this range, that have a VLT of less than 10% are considered to be effective in this regard, as recognised by the Green Building Council's Green Star™ Office Design and Office Interiors tools. Actual performance of fabrics will depend on the hardware configuration used. Automated sunscreens can be connected to building management systems for optimal control of glare and thermal efficiency.

The reduction of unwanted glare, heat and light entering buildings may contribute to reductions in energy consumption and associated greenhouse gas emissions, through reduced need for air conditioning, and hence reduced plant size and operating costs. Reduced glare and re-radiation from glazing exposed to direct sun will also support staff comfort and increased productivity.

HUMAN HEALTH

Health

Product contains antimony, however, it is bound into a polymer matrix and as a result, is unable to impact human health through skin, inhalation or eye contact. Flame retardants used in this product also do not attract any health or safety phrases in their MSDS

Comfort

These fabrics will aid in the reduction of thermal heat transmission into buildings, and greatly improve internal comfort visually and thermally through the reduction in light, glare and heat that enters the building interior.

Indoor Environment Quality

Some colours in this product range have a VLT of less than 10%, and hence are relevant to the achievement of Green Star® credit points showing the product is an efficient fabric at reducing glare. Product can be connected to building management systems for optimal control of glare and thermal efficiency.

ECOLOGICAL QUALITY 

Terrestrial

Emissions – There are process emissions associated with the production of polyester and with the setting of synthetics.

Physical – Product is petrochemical based, and will therefore generate limited physical pollution due to oil extraction.

Aquatic

Emissions – There are no toxics emitted by this product that will impact aquatic and marine ecosystems.

Physical – Product is petrochemical based, and will therefore generate limited physical pollution due to oil extraction.

Atmosphere
Greenhouse (GHG) –Fabrics utilise virgin polyester, which is fabricated from fossil fuels. Fossil fuels generate both atmospheric pollutants and greenhouse gasses on combustion. (See operational efficiency section below).

Through reducing the need for air conditioning, the greenhouse gases produced in the building may be reduced by shading devices.

Transport intensity Product is manufactured in Stammbach, Germany and transported to Australia by boat. GHG intensities for shipping product are shown below. Destination port is Melbourne, Australia.

Greenhouse Intensity for Container Shipping of:

  • Enviroblock – 0,872 kgCO­2e / m2

Table below provides land transportation greenhouse intensity figures to help calculate the greenhouse gas intensity of land transportation from shipping port.

Transport intensity figures sourced from Australian National Greenhouse Gas Inventory 1990, 1995 and 1999 and WWF International, Inland Navigations and Emissions, 2005.

Operational efficiency – The operational efficiency of shading devices significantly depends on whether they are fitted to create a trapped air space between the glass and the system. Blinds are most efficient when installed within a pelmet closed at the top; with the screen edges retained in tracks or fitted very close to the reveal, and touching the sill at the bottom.

This snug fit can decrease heat loss during winter by preventing the warm air from moving behind the curtain and cooling down when it contacts the cold glass (and vice versa). These thermal benefits may contribute to improved operational efficiency through reductions in energy consumption, associated greenhouse gas emissions and operating costs.

Re-use Efficiency – Unlikely.

Toxics and Pollutants – Antimony trioxide is used in the manufacture of polyester. Trevira CS fabrics contain low levels of antimony trioxide (less than 5ppm).

Ozone Depletion – This product produces no CFCs or HCFCs in its lifecycle.

Urban Heat Island Effects – Not applicable.

Noise – This product is not likely to affect noise levels.

Biodiversity
The use of virgin polyester generates biodiversity impacts through the atmospheric emissions generated during the refining and manufacturing processes of the virgin polymer. These have not been quantified in terms of impacts on biological systems, expect in the case of oil-spill impacts which, while rare, can have significant localised impacts.

RESOURCE DEPLETION 

Resource Efficiency

Since polyester is petrochemical (oil) based, and this is a virgin stock material, it would be more resource efficient if the material were manufactured utilising recycled polyester.

Embodied Fossil Fuel Energy

Transport intensity – Product is manufactured in Stammbach, Germany. EE intensities for shipping product are shown below. Destination port is Melbourne Australia.

EE Intensity for Container Shipping of:

  • Enviroblock: 10,71 Mj/ m2

Embodied Water
According to manufacturer, 3-4 L/m2 of water is used in the manufacturing process.

Durability
Polyester is a highly durable material with long expected life. It is however generally considered somewhat less durable than PVC-based fabrics.

The expected life of the fabric in both residential and commercial applications is over 10 years.

Reusability
If looked after, blinds can be returned for alteration for example to suit new window openings or to accommodate changes in office configuration or design. This will extend the useful life of the blinds. 

Repairability
Sponge clean for stains. More extensive damage may not be repairable.

Design for Dematerialisation
Not Applicable.

Design for Disassembly
Design for disassembly depends on the use of polyester fabrics for finished product. Fabrics can be used in systems where all the components (fabric, metal blind hardware components) can be stripped from the blind.

Recyclability
Product has the ability to be recycled, however manufacturer does not currently have the infrastructure to facilitate this.

Maintenance
Maintain fabrics according to instructions.

Product Takeback Scheme
Manufacturer in Germany offers a take-back scheme. Transport must be paid for by customer.

Extended Producer Responsibility (EPR)

ECOSPECIFIER ISSUES OF CONCERN / RED LIGHTS

Red Light Comment: This product contains antimony trioxide. According to the harmonised classification and labelling (CLP00) approved by the European Union, antimony trioxide is classified as R45: suspected of causing cancer, the most exposition does occur during manufacturing process; however if appropriate personal protection equipment are employed by workers, the risk is almost negligible.
