Green buildings often include measures to reduce energy consumption – both the embodied energy required to extract, process, transport and install building materials and operating energy to provide services such as heating and power for equipment. The environmental impacts that result from energy used in operating a building often far outweigh the impacts associated with energy used in its construction.
Low-energy buildings ypically use high levels of insulation, energy efficient windows, low levels of air infiltration and heat recovery ventilation to lower heating and cooling energy. Lighting and miscellaneous energy use is alleviated with LED lighting and efficient appliances. In addition, effective window placement (day lighting) can provide more natural light and lessen the need for electric lighting during the day. Solar water heating further reduces energy costs. Onsite generation of renewable energy through solar power, wind power, hydro power, or biomass can significantly reduce the environmental impact of the building.
Building construction and operation have extensive direct and indirect impacts on the environment by generating waste however sustainability construction processes can provide cost-savings through improved waste minimisation and waste management. Waste materials, that could otherwise be recycled back into other man-made products and materials, require disposal, which entails transport (and thereby, carbon emissions) to disposal sites, most often incineration plants, landfills (with landfill taxes increasing landfill taxes) and recycling depots. Waste can be minimized by using standardized, prefabricated and/or modular products and by recycling or reusing them.
VOCs (Volatile Organic Compounds) typically are industrial solvents, such as trichloroethylene; fuel oxygenates, such as methyl tert-butyl ether (MBTE); or by-products produced by chlorination in water treatment, such as chloroform. VOCs are often compounds of petroleum fuels, hydraulic fluids, paint thinners, and dry cleaning agents. VOCs are common ground-water contaminants. Many VOCs are human-made chemicals that are used and produced in the manufacture of paints, pharmaceuticals, and refrigerants. VOCs have a high vapour pressure and low water solubility.
A bio based material is a commercial or industrial material (other than food or feed) that is composed, in whole or in significant part, of biological products, renewable agricultural materials (including plant, animal, and marine materials) or forestry materials. The bio based content value of a product is determined by weight and expressed in percentage (%). The bio based content is calculated based on the total weight of all bio based materials going into production of the product divided by the total weight of all the raw materials used to produce the finished product.
Renewable energy is energy generated from natural resources — such as sunlight, wind, water, rain, tides and geothermal heat — which are renewable (naturally replenished). The renewable energy is expressed in percentage and calculated on the basis of renewable energy going into production divided by the total energy required to produce the finished product.
Maintenance/cleaning is performing the routine actions which keep the device/product/item in working order (known as scheduled maintenance) or prevent trouble from arising (preventive maintenance). Maintenance is described as not required or daily, weekly, monthly and yearly that refer to the frequency of maintenance or cleaning required to keeping a product/material in working condition.
Indicative price refers to the tentative unit selling price of a material/product.
Embodied carbon refers to total greenhouse gas (GHG) emissions, quantified in carbon dioxide equivalent (CDE or CO2e) units, associated with of a specified material.
Reducing water consumption and protecting water quality are key objectives in sustainable buildings. To the maximum extent feasible, facilities should increase their dependence on water that is collected, used, purified, and reused on-site. The protection and conservation of water throughout the life of a building may be accomplished by designing for dual plumbing that recycles water in toilet flushing.
Waste-water may be minimized by utilizing water conserving fixtures such as ultra-low flush toilets and low-flow shower heads. Bidets help eliminate the use of toilet paper, reducing sewer traffic and increasing possibilities of re-using water on-site. Point of use water treatment and heating improves both water quality and energy efficiency while reducing the amount of water in circulation. The use of non-sewage and greywater for on-site use such as site-irrigation will minimize water consumption.
Recycled content here refers to post consumer recycled content unless otherwise stated. Post consumer recycled content refers to materials that are reclaimed from products that have already served their intended end use as a consumer item. Waste from industrial processes is not considered post-consumer.
The recycled content value of a product is be determined by weight and expressed in percentage (%). The recycled content is calculated based on the total weight of all post consumer recycled raw materials going into production of the product divided by the total weight of all the raw materials used to produce the finished product.
Durability refers to typical replacement interval or useable life of a material/product that indicates the expected life (in years) of products / materials after which replacment is required. Durability is described as low, medium and high that refer to typical replacement intervals of 0-10 years, 11-25 years and more than 25 years respectively.
Reuse is to use an item more than once. This includes conventional reuse where the item is used again for the same function and new-life reuse where it is used for a new function. In contrast, recycling is the breaking down of the used item into raw materials which are used to make new items.
Packaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Sustainable packaging is the development and use of packaging which results in improved sustainability and reduces environmental impact and ecological footprint.
Recycled content in packaging will be determined by weight and expressed in percentage and calculated based on weight of the packaging raw materials going into production divided by the total weight of all the packaging raw materials.
Availability refers to the time required to make products / materials ready for shipment from the date of order. Availability is described in number of weeks ex works.
We believe the actions of our Suppliers are increasingly important factors in our sustainability performance and our Suppliers should be viewed as partners in our sustainability journey. We take great care in selecting the companies who supply us with products and services, and expect each of them to operate to internationally recognized standards and appropriate codes of practice.
