Sustainable Means …
When we apply the word “sustainable” we mean homes that are designed to reduce the overall environmental impact during & after construction in such a way that we can meet the requirements of the present without jeopardizing the ability of future generations to reach their own needs. We accomplish this by:
- Efficiently using energy, water, land & other resources
- Protecting occupant health
- Reducing greenhouse gases, pollution, waste & environmental degradation
It is a fact, which nowadays households & other living areas in which people live, or reside most of the time contribute CO2 emission & greenhouse effects as much as global warming, which threatens to all humans & their health, as well as natural resources which balance was disturbed a long time ago. Sustainable Greenhouse or Eco House is one of the possible solutions, which with one part can contribute to solving this global burning issue.
When people talk about building sustainability or green building, they’re normally referring to things like:
- the extent to which the construction of the house uses energy & which materials are used
- its ongoing impact on the environment in which it exists
- the house’s design, & how that affects the need for things like artificial heating, cooling & lighting & water dem&s
- energy & materials required to maintain or renovate the building over the course of its life
- the overall lifespan of the building
- the resources required to demolish the building, & how its byproducts are either disposed of or recycled.
There is a question, how this house, or what does it well for a living! That is the house which is energy efficient by itself, environmentally healthy, respectful for the natural environment, comfortable for family life, in other terms, to be sustainably built of green or recycled materials, & this house should use alternative energy resources.
In the broad context, sustainable architecture seeks to minimize the negative environmental impact of buildings by enhancing efficiency & moderation in the use of materials, energy, & development space. Most simply, the idea of sustainability, or ecological design, is to ensure that our actions & decisions today do not inhibit the opportunities of future generations.This expression can be used to describe an energy & ecologically conscious approach to the design of the built environment.
Sustainable homes have three key elements.
1. Environmental sustainability
The house is designed to reduce greenhouse gas emissions, save water & energy & reduce waste during construction & the house’s lifetime.
2. Social sustainability / universal design
The house is designed to prevent injuries through built-in Safety features. It has security elements to reduce crime & improve the occupants’ sense of security. Features are also used to provide flexibility & comfort for people of varying abilities & at different life stages, including children & people with limited mobility.
3. Economic sustainability
The house is designed to save money during construction & over the lifetime of the house. Careful planning avoids the need for major future renovations & reduces costs associated with energy use, water use & maintenance.
What makes a Sustainable House?
A sustainable house is simply one that gets effective use of resources & energy flows available to the site.
- It uses the sun to keep the house warm in the winter, heats the water & produces the power.
- It uses the wind to channel prevailing breezes to calm in summer.
- It collects the rain that falls, to be used efficiently throughout the house & garden.
- It uses the mass of the earth on which it sits to maintain the stability of temperature.
- It uses the l& to provide native habitat & human nourishment.
- It uses the soil to recycle wastes.
More broadly, it minimises its footprint by choosing materials that avoid habitat destruction & limited resources, are low in embodied energy, & implements technology that uses electricity & water efficiently.A Sustainable House is one that has a sense of sanctuary, is light & warm, connects the user to the environment, & is a healthy place in which to live & grow.
How to- Action plan
Every action plan should contain a series of targets, measures to achieve them & methods for measurement & review of the processes. The government’s approach is based on ten targets, as follows:
- Re-use existing assets – The decision to build in the first place should be scrutinized. Refurbishment may be a better option. In any event, the preferred option should be brownfield development, & this is encouraged wherever possible.
- Design for minimum waste – The potential for misuse can often be reduced at an early stage. This needs precise & accurate specification, which is often overlooked, as well as a design concept to maximise re-use & recycling of materials. Designers are usually best placed to be aware of new ideas, & this also addresses one of the leading Egan principles of using innovation in problem solving & training.
- Lean construction – The targets of supply chain integration, site management, best value, improved communications & user focus can all be achieved sustainably.
- Minimise energy use – This should include energy in materials manufacture as well as considering one of the most considerable power uses, transport.
- Energy in use – Heating (& cooling) of buildings has one of the most significant impacts. Buildings consume vast amounts of energy during their lifespan. Relatively simple considerations such as position or orientation of buildings on a site can generate significant benefits. The use of design solutions such as passive heating, natural light, air movement & thermal mass can contribute significantly, as can the use of energy from renewable sources such as solar or wind power.
- Pollution – The four significant sources of pollution from the construction industry; waste materials, emissions from vehicles, noise & releases to water, ground & the atmosphere, are all well known, but often not enough is done to combat them.
- Biodiversity – Look for opportunities throughout the construction process from the extraction of raw materials, through the construction phase, to the use of buildings & their l&scaping, to provide, protect & enhance natural habitats. As with many of the other issues, this is also best addressed at the design stage.
- Conserve water resources – Another design issue, natural resources may be better used by including measures for higher efficiency in use. This may not be immediately evident in the building process, but there is much potential for gain when considering costs-in-use. Information can be gained from water & energy audits of existing buildings & the technique of benchmarking can be used to significant effect.
- Respect people & their local environment – Although sometimes not rated as highly as other items, this is one of the cornerstones of government sustainability policy, & has resulted in a separate “respect for people” initiative. Consideration should be given to all those upon whom the project may impact, from the local community to persons directly employed in the construction.
- Set targets – these are the measures by which the success or failure of all the other criteria will be judged. There is a wealth of benchmarking, best practice & additional management systems information which is being developed for construction & sustainability in particular. Several organizations have already introduced environmental management systems to evaluate performance on construction projects. More recently, environmental management systems such as ISO 14000 as well as some evaluation schemes such as the BRE Eco-homes st&ard, have provided a means for assessing & managing their effects.
It can be shown that as well as the general sense of well being associated with contributing towards the preservation of the planet & the broader community, a strong case can be made for the business benefits of ado
