E-Waste
E-Waste

This term doesn’t refer to all the spam filling your email box, though those messages do waste plenty of time. E-waste is actually the millions of tons of electronic products, computers, cell phones, and the like that enter the waste stream worldwide each year. As newer, better, cooler gadgets come on the market, the piles of e-waste grow ever higher. Aside from their contribution to landfills, many electronic devices contain hazardous materials, such as mercury; many also contain valuable, reusable materials that can be recycled. There are some simple ways to limit e-waste: Buy quality products that can be upgraded instead of replaced; donate old equipment (to a school for instance); and seek out recycling programs when you’re ready to dispose of an item. Also called electronic waste.

Eco Anxiety

Eco-anxiety is a chronic concern over environmental issues. This is not recognized as an official mental disease or dis-order. Rather it is a 'label' given to being overly concerned to the environment and a general feeling of helplessness in how to 'fix' it.

Being concerned about the environment is a good thing; in order to overcome any concerns you may have, we suggest

  • Read the articles on this site (its not as bad as some people are painting it)
  • Educate yourself on the issues at hand. Having a better understanding and knowledge set will allow you to internally 'rationalize' your concerns and work out how to actually do something effective. Do not be blindly guided by others, keep your own council and point of view.

Eco Architect
An Eco Architect is an architect that specializes in producing designs that should:
  • Minimize environmental impact, across the whole life cycle of the resultant building;
  • Maximize the use of recycled or reclaimed materials;
  • Minimize the operational costs of the buildings by employing energy efficiency techniques in the building design.

The end result should be a building which is good for the environment and cheap to live in.

Although, with the increased focus on being green in building, quite often regular architects either have direct 'eco' experience or have access to experts or resources to assist them - so do not select on the basis of an architect being eco alone.

Eco Architecture

Eco Architecture refers to designing buildings with a strong green and environmental element to them; e.g sustainable and minimizing the environmental impact of the final design.

Note: This does not necessarily mean existing buildings cannot be made more 'eco' rather this is focused on taking a new building and designing it from the ground up to be more eco friendly. When building it pays to consider the benefits of reusing an existing structure over knocking down and replacing it.

Eco Conscious

Being an informed purchaser. Knowing or having an understanding of what effect what you are doing, buying or using has on the environment.


Note: This is not just buying 'eco-friendly' or 'green' products or services, rather you have a more direct appreciation of your impact on the environment based on knowledge & act accordingly.

Eco Friendly

This refers to a product or service having minimal impact on the environment in its provision. Unfortunately how 'minimal' is determined is somewhat open to interpretation and often depends upon context. This is also a phase that is often hijacked as part of a green washing campaign; so double check any claims.

Eco Fusion

A very fuzzy 'Eco Marketing' term used to represent the fusion of many disciplines (including education, training, experience, materials availability, and eco inventions); on the premise that we need to tightly merge those disciplines to solely focus on 'improving the environment' in light of climate change. Often used to contrast against more loosely coupled business processes and distinct disciplines as being more 'green'; when often the real motivator is for the Eco Fusion advocate to 'control' more of the purchasing and business process for direct profit; in essence a form of ecofraud.

Eco Lights

Eco Lighting is lighting which is both energy efficient and has a light burden on the environment, i.e. they are easy to recycle and repair.


Eco Lighting can also refer to smart lighting that is able to reduce its energy consumption in response to its need, i.e. lights that automatically turn off when people leave a room or lights in a garden that only come on at night or respond to movement. Eco Lights can also be self contained solar powered units often used in gardens.

Eco Marketing

This is when a business deliberately markets itself as being 'eco' above and beyond the core functions or services of the business; when in actuality the business is not eco at all. This form of ecofraud is done to  firstly pray on peoples tendency to assume anything eco is good; then secondly to utilise people's tendency not to question anything eco to sell on its core functions or services easily to eco minded people.

As we always recommend, make sure you have the real facts at hand (look on this site and use our search engine) and always shop around and do not over prefer the 'eco businesses' - quite a few businesses now are eco minded without feeling the need to promote it.

Eco-architect

An eco-architect is someone in the building design field (architecture) who either has specific training in designing eco-friendly houses, or equivalent accumulative knowledge.

This used to be quite a specialist field, as the methods and techniques employed were only understood by a minority of architects and designers; although now the ability to create eco-friendly houses can be enacted often by a regular architect, designer or drafts person using either specific software applications or following well understood principals of eco-friendly design (such as passive solar). Also the increased focus by local goverments through planning law on green building has made it almost universal that all architects or designers have had some experience with eco-friendly design.

Ecofeminism

Term introduced (“ecofeminisme”) by Francois d’Eaubonne in the 1974 text Le Feminisme ou la Mort. Dissatisfied with ecological analyses that leave patriarchy out of account, ecofeminists out parallels between how men in the West mistreat women and how they mistreat the Earth: in both cases a relationship of power, control, a will to dominate, and a pervasive fear of of the fact of interdependency. A twist on this is the patriarchal habit of objectifying women while feminizing the environment; women are then seen as less mature or human because "closer to nature."

Ecofraud

This term is associated with a business/group or individual who engages in or who presents themselves as being a subscriber to sound science based eco and environmental principals; when in fact they are either:

a) solely being 'Eco' for personal or monetary gain, with little real regard for any eco or environmental principals or,
b) totally misrepresenting, misapplying or distorting sound scientific based eco and environmental principals to add weight to an argument or issue.

The first case is usually very deliberate in intent; whereas with the second case, a person or group can be 'duped' into believing and then promoting an 'eco fact' - when in fact it may have little empirical or scientific basis when the bigger picture (either in time or space) is considered.

This in itself is nothing new, misquoted and misunderstood information abounds in everyday life; but what is concerning is the degree of lack of question and real knowledge share that often occurs when people are confronted with an 'Eco fact'; please demand to be informed. Remember: a decision based on ecofraud info could well be doing longer term harm to our Environment.

Ecofriendly

Environmentally friendly (eco-friendly and nature friendly) are synonyms used to refer to goods and services considered to inflict minimal harm on the environment.

To make consumers aware, environmentally friendly goods and services are often marked with eco-labels. But because there is no single international standard for this concept, the International Organization for Standardization considers such labels too vague to be meaningful.

Ecohome

An Ecohome is a house which has been designed from the ground up to be environmentally friendly whilst at the same time energy efficient.

Usually this requires a custom build  (which can be expensive); although with some careful thinking it is possible to make an existing property more eco friendly whilst preserving the embedded energy incurred when it was built. Too often existing properties are demolished that could have been made 'good' with a bit thought.

Ecosmart

Ecosmart refers to a system or service that has been designed to incorporate 'smarts' into its design to actively manage and reduce its impact on environment. This can be done using a mix of static and dynamic features. 


A static feature could be the use of high R insulation or a building orientation to maximize solar gain. A dynamic feature could be energy management that is aware of usage and how environmentally friendly a given energy source is compared to its usage. This could be as simple as lights that turn themselves off when nobody is in a room.

Ecosmart could also refer to the consideration of the whole life cycle of a given product, so it does not contribute to E-waste, is repairable and ultimately recyclable. 

Ecosmart design can also be applied to a whole building or structure, such as someone's house, using a variety of smart subsystems grouped together to create an automated environmental benefit.

Note: Just be clear, an ecosystem by definition does include 'us' and what we do, we all inhabit the same set of systems. Therefore be careful of ecosystem analysis's done without consideration of what impact (both in the good and bad sense) humans have made. There are very few ecosystems that we do not engage with over the longer term.
