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

Metallised product contains aluminium. Aluminium smelting in the production of aluminium is a known cause of fluoride emissions that can cause a variety of health impacts.

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.

Electromagnetic Radiation

Metallised fabrics are anti-static, and as such they repel dust.

Safety

The low VOC emissions from the blinds when in use, make the blinds a safe option, both for installers and consumers.

Accessibility

Not applicable.

 

ECOLOGICAL QUALITY

Terrestrial

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

The metallised version of the product contains a small percentage of aluminium. The production of alumina from bauxite ores uses a chemical treatment, known as the Bayer Process (see Glossary). The alkaline mist associated with this process may have adverse land and vegetation impacts.

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

Mineral extraction of bauxite used to make aluminium will disrupt landscapes and alter ecosystems. Because bauxite deposits are found near the Earth's surface, mining requires removal of topsoil and overburden before deeper excavation occurs

 

Aquatic

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

The extraction and production of aluminium products have associated emissions to aquatic environments that have localised impacts around production facilities.

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

Bauxite residues of red mud are often disposed of in tailing dams where the mud is allowed to settle. The excess water is discharged into marine environments.

 

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).

The process of manufacturing aluminium has very high energy requirements and subsequent GHG levels, but in this case the thickness of the aluminium is such that these impacts are not significant.

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

Greenhouse intensity –

  • Enviroshade– 0.39kgCO2e / m2
  • EnviroshadeAlu & Tecno–  0.41kgCO2e / m2

* Calculation is based on specific data sourced from Bath University, United Kingdom.

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:

  • Enviroshade– 0.03579 kgCO2e / m2
  • EnviroshadeAlu & Tecno– 0.03648 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.

Bauxite mining leads to modified soil profiles, topography and drainage which impacts natural vegetation and biodiversity.  The oil extraction process results in the release of toxic drilling by-products into local rivers, while broken pipelines and leakage result in persistent oil spillage.

 

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.

Aluminium is the third most abundant metal on Earth and the most abundant in the Earth's crust. The primary mineral source for aluminium is bauxite ore, a non-renewable resource with an estimated supply of 180 years based on current Reserve Life Index (RLI) (Source: Meyer, 2004, Availability of bauxite reserves, Journal of Natural Resources Research, p. 161).

 

Embodied Fossil Fuel Energy

  • Enviroshade: – 13.82MJ / m2
  • EnviroshadeAlu & Tecno: 14.03MJ / m2

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:

  • Enviroshade– 0.4392 MJ / m2
  • EnviroshadeAlu & Tecno– 0.4477 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
No.

 

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.
