Construction And The Environment - Effects On Soil

Soil is definitely the mainstay of the environment, whether in its loose soft form or in the form of rock. The following are common ways in which construction activities distract the normal form of soil, thereby shaking the environmental mechanisms that the same support.

· Mining for building materials for example stone or clay for building blocks or for cement alters the normal form of the landscape. It leads to formation of derelict landscapes, most of which cannot support the normal forms of life. Open mines are also notorious for holding surface water in pools, most of which habour a different form of life.

· Blasting as is common in rock excavation destabilizes the ground, posing the dangers of earth movement like landslides. The breakage of rock enhances the rates of weathering, thereby breaking up rock even more faster.

· Mass excavation of topsoil deprives the ground of life - supporting soil stratum.

· Creation of cess pools and soak away pits for sewage disposal lead to the intoxication of soil. Treatment ponds have a similar effect.

· Activities leading to the reduction of water available, whether surface or sub surface, leads to a reduction in soil water, thereby altering its live supporting capabilities.

· Leaving open sections of soil like is common in embankment and uncovered sections exposes soil to agents of erosion, notably rain, thereby shaping the landscape as well as moving humus rich top soil from one section to the other.

· Compaction of soil, especially on a large scale and in many layers alters the normal stratification as well as penetrability by plant roots as well as percolation by water.

· Importation of alien soils of a different kind creates an inconsistency and as such a disjoint. It also creates an anomaly in the environmental patterns in the constructed area.

As noted, soil is a very crucial part of the environment and it needs to be treated with utmost care. Hampering the normal conditions of soil amounts to a distraction in the normal flow of life in the environment. Soil is perhaps among the most crucial pillars of life. It is also among the biggest victims of the activities of construction. This makes considerations on soil conservation measures in any construction works to be very carefully thought out and implemented. It is the duty of all the stakeholders involved to work together to reach the goal of minimum soil disturbance in all the construction projects they are involved in.

Construction And The Environment - Effects On Climate

Climate change is definitely the most identifiable global concerns today. It has taken centre stage in world for and has raised many mitigative measures to counter the worrying trends. Construction is one of the contributors to climate change as can be derived from our previous examples, which are summarized below.

· Lowering of the water table, making it more difficult for plants to survive.

· Hampering with weather conditions for example by altering normal rain formation trends of a specific area.

· Clearing vegetation, reducing moisture available for rain formation.

· Reducing water available to water bodies with similar effects as above.

· Increasing water available in an area for evaporation and thus more precipitation in an area.

· Industrial and residential emissions, altering normal air conditions.

All these and more are ways in which construction activity has continually led to climate change. The conditions of an area are continually changed to form completely different ones. Some of the common direct results of these include:

· Depletion of the ozone layer, risking us to harmful radiations from the sun.

· Reduced precipitation, resulting to more cost of acquiring water.

· Increased precipitation, requiring more elaborate ways of removing excess water or even requiring project design changes.

· Reduction of food in the food chain, leading more food chain conflict and imbalances.

These are just but examples. The blatant truth is that climate change is becoming a very thorny issue and it needs to be addressed by all and sundry. All avenues available for averting this trend should be sought and followed. Key players in the construction industry ought to join hands with their counterparts, especially in the manufacturing industry, to come up with eco friendly products and procedures. Activities that lead to toxic emissions, for example, should be shunned as much as possible and if not, should be put at a minimum. Buildings should be provided with utilities that lead to less wastage, for example by reusing some materials. The issue of cost and value should be clearly addressed to make sure that the better advantage goes to the environment as opposed to the developer alone. Consultations should be done to ensure that all the hurdles to environmental conservation that arise in any project are properly handled at the earliest opportune moment.

It is always important to remember that our climate determines just how easy our tomorrow will be. It thus calls for all that are involved to put into consideration the idea of continuity in the construction project at hand.

Construction And The Environment - Green Building

This is a conclusion to our series of articles on ways in which construction affects the environment. Green building is a concept in construction which aims at creating environment friendly construction. The aim here is to reduce the impact of construction on the environment as well as coming up with remedial measures to resuscitate the already chocking environment. Below are just examples of green construction practices.

· Using renewable energy sources in buildings for example solar and wind energy in the place of electricity and fossil fuels.

· Coming up with designs that require minimum energy supporting systems like maximizing on day lighting in buildings as opposed to electric lighting.

· Reducing the use of timber in construction, especially rare and deciduous types, and in their place using fast growing species like bamboo and softwoods in controlled forests and plantations.

· Reusing timber as well as timber wastes like saw dust to make timber replacements.

· Tapping into rainwater and other precipitation for use in buildings to replace or supplement water from other sources.

· Reducing water wastage by making use of pressure control valves, low flush cisterns and the like.

· Reusing grey water (all used water in the house, other than from closets, bidets and such).

· Using porous materials in parking and general surfaces to allow for percolation of water for replenishing sub surface.

· Incorporating gardening and greening in built up areas, including the introduction of green roofs.

· Reducing earth-moving activities for construction works.

· Avoiding construction in environmentally fragile areas for example water catchment areas.

· Reducing the wastes from buildings that end up in land fills by ensuring sorting at source. A good example is where biodegradable wastes are put in different bins and used as fertilizers.

· Rehabilitating derelict land and mine fields by planting trees and such environmental conservation measures.

All these and many other similar measures will definitely nurture the environment. They will however need a lot of deliberation and forward planning so as to make success. It is also worth noting that green building is usually more expensive upfront but could be affordable in the building life cycle. Furthermore, the extra cost in money will be compensated in a sustainable environment.

Green construction is a collective responsibility and should be sought by all and sundry. Architectural association and building regulatory boards the world over should put all the necessary efforts to have their jurisdictions adopt green construction. Governments should also demonstrate green building in their projects to have their subjects easily accept them. Learning institutions and training institutes should also put enough emphasis on these procedures. Green construction materials and equipment should also be zero rated to reduce costs as well as create a preference.

Construction And The Environment - Introduction

As seen in my previous articles, construction is among the major human activities that result to landmark products. The activities of construction produce items that stand on land replacing natural features or even changing them. Some of the activities change the landscape by either adding or omitting some of them. Construction also makes use of a good number of materials borrowed from the environment, whether in their natural state or in a processed form. Furthermore, the usage of the product of construction leads to the production of elements of waste which are then directed to the environment, mostly in a cleansed manner, although in most cases, this is not fully accomplished.

In all these activities, the environment is impacted in one way or the other. In many occasions, they are detrimental to the environment, with the only variable being the degree and nature of such impact. While some effects are short - term and easily overcome, others are irreversible and thus leave a permanent mark on our environment.

Being among a global concern, environmental impact reduction should be reduced, reversed and even prevented from occurring by all that are involved. This will include all stakeholders in the construction industry, as it is a potential cause of such ills to our environment. The following are just a few ways that various players in the construction industry can use to achieve environmental friendly projects:

· Prospective builders should be advised on the need and ways of building environmental friendly buildings.

· Designers should see to it that matters environment are handled with utmost care in all projects they handle.

· Statutory bodies should ensure that construction designs and methodologies adopted for any upcoming projects are in tandem with the responsibility of environmental care and sustainability.

· Occupiers should ensure that no activity that they are engaged in result to environmental jeopardy.

When all and sundry understand the need and the ways of caring for the environment, then we will be a step closer to good environmental impact management as far as construction is concerned. It is also worth noting that for such a goal to be successful, it calls for the collective responsibility by all. Otherwise, the sweat of one person will be watered down by the ignorance or omission of the other. Teaching all the stake holders on these matters will make sure that they have a clear knowledge of how to minimize the detriment that has continued to eat away our environment.

Construction And The Environment - Effects On Water

In this regard, we will consider the following types of water;

· Surface water: this refers to water appearing on the surface of earth. Examples here include rivers, lakes, oceans, swamps and so forth.

· Ground water: this refers to water appearing in the ground, also referred to as sub-surface water. It is usually contained in rocks known as aquifers and forms a level commonly known as water table. Water table is usually an intermittent and rises or falls depending on the amount available in the feeder for instance through percolation.

· Precipitation: this refers to the various forms in which water appearing in the atmosphere is availed to the ground. It takes the form of rainfall, dew, hail storms and the like.

A number of common construction activities can hamper the normal patterns of the said forms of water, consequently interfering with the normal form of nature. The following are ways in which this happens;

· Sinking wells for drawing water results to a lowered water table level. This, for example, strains the vegetation drawing water from the same, hampering their growth.

· Building extensive hard surfaces reduces the amount of water percolating into the ground, depriving it of subsurface water and resulting to a lowered water table.

· Clearing extensive tracts of land for construction activities reduces the levels of moisture in the atmosphere and currently reducing the rate of precipitation expected.

· Construction of water bodies like reservoirs deprives normal flow downstream, hampering the normal aquatic patterns. This could also lead to an increase in moisture in the air, resulting to more precipitation.

· Disposal of effluent from construction sites as well as built up areas into water bodies like rivers alter the ordinary quality of water, thereby changing the life supporting mechanism for aquatic life.

· Building of barriers like trenches will change the normal flow of surface run off, thereby altering the usual rates and patterns of percolation.

· Mass rain water harvesting whether in above ground or under ground tanks or reservoirs will also have similar effects.

While these are only examples, the truth is that construction has a remarkable effect on water patterns in the environment. This effect increases with increase in magnitude of construction work being undertaken as well as ignorance in limitative measures possible. It should therefore be a number one priority in every envisaged project to plan for ways of reducing tendencies of altering water patterns in our environment, for this directly affects the environment and all that it carries with it.

Construction And The Environment - Effects On Vegetation

Vegetation is among the clearest indicator of life in our environment (probably second to the animals). It is also a key pillar in the environmental dynamics especially the weather. Vegetation takes different forms and shapes and vary from one type of environment to the other. Construction activities affect vegetation in the following ways;

· Construction materials. Construction has drawn a lot from natural vegetation in the following forms;

o Timber: this is the most common material in construction, since time immemorial. This could either be used in its raw form for example in posts or in machined timber for example tongued and grooved panels for ceiling construction. Frames for structural work like roofing and timber walls are also a very common use of wood. Other machined forms, for example plywood are also very common in construction. The tricky thing with timber for construction is that the preferred timber comes from hardwoods, which are rare, hard to breed and take a long time to mature.

o Roof covering: reeds and such vegetation have for long been used in the form of thatch for roofing, mainly in informal settlements but also in motels and hotels, especially beach resorts.

o Furniture: Timber furniture has for long been the most preferred in houses. This has a big impact on trees as most are purely out of wood and especially hardwoods which are very hard to come by as previously explained.

· Clearance for settlements: large forests and other such vegetation's have been cleared for settlement activities, whether for purely construction work or in combination with other activities like farming.

· Importation of vegetation and soils: introduction of alien plants, especially for landscaping compounds also affects the environment by changing things like normal photosynthesis activities by normal plants. Importation of soils will also lead to the support of different kinds of vegetation, especially where this is supplemented with irrigation.

· Dumping of material: The disposal of material, whether waste or excess spoil, introduces a new formation on which new forms of vegetation are most likely to grow. This may also lead the death of the existing vegetation.

· Dewatering of land: This is common in swampy lands and is mostly done to ensure good compaction of earth.

Following these examples, it is clear to see just how extensively the activities of construction have impacted on vegetation and by extension, on our fragile environment. It is very important to ensure that whatever technologies that are adopted in construction projects are environmental friendly, by reducing impacts to the lowest possible levels.

Going Green - Construction, Which the Environment Loves!

Sustainable building, green building, green construction or simply "going green" is a concept about eco-friendly construction. It involves the application of practices and technologies that are environmental friendly, right from the construction, to occupancy, maintenance, renovation and finally demolition. This concept first started rising in the '70s when concerns regarding harmful impacts of construction industry on environment, and its resources, started growing.

Although no international agreement is available regarding carbon reduction and eco-friendly construction, there are organizations present that are working for the sustainability of natural resources, toxic reduction, recycling, waste reduction and application of energy efficient practices etc, such as EPA in the US. The EPA requires the construction industry to design and build buildings with eco-friendly materials and methods. This is not the only reason why construction industry has started following green trends. Many environmental-concerned companies and individuals have started emphasizing on green building, when doing a new construction or renovation project in their homes, commercial properties or work places. This is a very good sign because it educates and encourages the construction industry to work towards developing new sustainable building techniques. The need of going green gets more imminent as a recent study shows that the Ozone layer had depleted by 40%, which is alarming.

The basic principles of sustainable building in new construction projects and retrofitted properties include:

· Efficient use of land, water, energy and other resources.
· Improving the health of everyone living in a building.
· Providing clean environment to increase employees' performance.
· Reducing pollution and other waste emission in the environment.
· Educating public about the need and merits of green building.
· Using local materials and manpower so as to avoid transportation cost of these brought from other towns and areas.

Not only it is important to derive methods for going green, it is equally important to use the present resources in an intelligent and efficient way.

Water Efficiency:

Two-third of the Earth consists of water, not all of it readily usable. It takes a lot of work and energy to make water usable which means there's a shortage of water and therefore, we need to use it efficiently. A popular way of maintaining the quality of water and reducing its usage is to use dual plumbing system, which recycles the water with every flush of the toilet. Low-flow showerheads and low-flush toilets can also increase water efficiency during the life cycle of a building.

Energy Efficiency:

There are a lot of ways to use energy efficiently. Few simple methods are to use light paint colors on the exterior and interior of the building. The exterior light colors will reflect sunrays and as a result the interior of the building will remain cool reducing the need of air conditioners and such. Interior light colors will also help reflect the natural light, which will reduce the cost and need of electric lighting. Modern insulation systems can also be installed in walls and floors to use the energy efficiently. Building can be designed with passive solar building ways that uses windows and walls to help shade the property in summers and provide natural light in the winters. Other ways to use energy efficiently are solar power, hydropower and wind power etc.

Material Efficiency:

Using material that are recyclable and re-usable is an important part of sustainable building. It involves using natural materials such as straw bale, clay and bamboo for the construction or renovation of the building.

Waste Reduction:

Compost bins are a great way to reduce waste emission by the occupants or work force in a building. Waste reduction can also be achieved by recycling the waste into fertilizers. Use of water instead of paper towels can also reduce waste going in the landfills. Some highly sophisticated waste reduction techniques can also be applied, but they may be a little costly.

We only have planet Earth to live on. We don't have any other place to go. We need to keep earth and our environment safe and healthy, and Earth's natural resources sufficient for our generations to come. We've already harmed the Earth enough. Now is the time to go green.

Simple Homes and Green Construction Ideas

Have you ever dreamed about building a home of your own, only to be awakened to the reality that it would cost a fortune? Perhaps you don't want to drown in a sea of debt. There are ways to build a home of your own without breaking the bank.

For example, one of my relatives, who was visiting us in Texas after moving to Africa as a missionary with Youth With A Mission, got ahold of a book I had bought online, Homework: Handbuilt Shelter, by Lloyd Kahn. He was so inspired by the book that when he returned to Zambia, he bought a parcel of land and built a home out of a mixture of natural and man-made materials for around $1500, which is pretty impressive.

But how do you build one in N. America where land prices are so high and materials cost so much? If you do not own a piece of land, it is wise to make your dwelling portable so that you can move it as needed. Remember that here we have high prices, but we also have lots of things that people throw away or give away for free. There are also many areas where there are free materials found in nature that you can use.

If you are looking for a simple, affordable structure that is semi-portable, strong, well insulated, wind, water, and weather proof, then the yurt or ger, which is common in central Asia is the best. Most yurts and gers are designed to withstand high winds, freezing weather, rain, and cold. These have become popular in other parts of the world, and there are several places online where one can find instructions on how to build a yurt out of recycled materials, materials from nature, or store-bought materials. These are almost-free structures that any determined person could build.

The teepee of the plains Indians of N. America is another remarkable design for a portable, green shelter. The American Indians were able to stay warm in these simple structures by building a fire in the middle of the teepee. Be very careful if you build a fire inside a teepee. If the teepee cover is made out of a plastic material, it will melt when you build a fire inside it. Fire dangers and damage can be reduced if the teepee is made out of canvas and natural materials and to reduce smoke, it should be at least 12' high, and 14-18' is best.

Some of the indigenous tribes in N. America built wikiups to protect them from the elements. For a temporary shelter in emergency, the wikiup can't be beat. These can be made of saplings, sticks, grass, straw, tree branches, and leaves.

Moving on to more stable structures, if you plan to build a permanent, green home, it is wise to first secure the land where the home will sit. The best place to build an affordable, handmade, green home is in a rural area. Look for an area away from major cities and highly populated towns. Building officials in farming and rural areas will be less likely to harass you over your unique home. If you get to know the locals, you may find a farmer or property owner that is willing to sell you a parcel of land. Make sure that all agreements are put on paper and signed by both parties, and that a title to the property recorded in your name with the county clerk.

Straw bale houses are a popular method for building a simple, affordable and green home. Straw bales offer great insulation. It is bommon to place the straw bales on a platform that supports the walls to prevent them from getting wet, and the exterior and interior walls that the bales form can be protected with a stucco or mud plaster. It is important to add structural supports in the walls between the straw bales. Certain municipalities and counties limit the use of this type of construction, so check with the local building authorities before proceeding.

Cob is another method of green building that makes use of a mixture of clay, sand, and straw to form earthen walls. Cob buildings can be made that have unique shapes and character. If you are in a city or highly regulated county, there are building code guidelines and limitations about what you are allowed to do with cob construction.

Some have built their homes underground, such as the earthship. Many green home builders have manipulated and designed the earthen walls around them as a protective sheild, as part of an insulation design, and for the "conditioned cave" effect. Properly designed underground construction provides several advantages, including energy savings, security, and less visibility. The only main drawback to underground construction is the possiblity for moisture intrusion such as is common in basements. A properly built and situated underground home can withstand hurricanes, tornadoes, and even nuclear events. Building underground is also used as a way to hide the true size of a home.

Some have built ceramic domes, using earthbag construction. Nader Khalili, an Iranian-American architect perfected this art, and presented it to the West. Earthbag or Super Adobe construction can be strong, efficient, and useful for budget construction projects.

In addition to these more direct approaches to green building, there are construction products currently being developed that make use of used, recycled, and sustainably produced materials. Some of these materials are better and safer than others. It is wise to fully investigate the production process for these materials before using them to construct your home. Some contain chemicals that may be harmful to your family's health, so doing your homework on the manufacturing process is advised.

Whatever you desire to build, start small today and test your ideas. Remember to plan ahead, get the advice of professionals, and read up as much as possible before committing your time and finances to the project. It would also be wise to befriend several contractors who can give you advice on how to make things go forward without difficulty.

Sustainable construction for education

Sustainable construction is now one of the agenda. There is currently the social, political and legislative pressure to ensure that new school buildings are considered "sustainable". It is a part of your disk for an eco-school. This includes any shelters and viewpoints, so that new classrooms.

With so many things to think about everything mainly focused on the budget and on time, how can you ensure that your school building is truly sustainable and causes minimal impact on the manufacturing, construction, life environment; and, at the end of his life, demolition. Our recommendation would be to choose wood for sustainability and the site of manufacture of the budget and the speed of delivery.

Wood is the material of construction only natural, renewable, recyclable in the world: it has been used in the construction of several thousand years. Now with the FSC or PEFC certification you can be confident in its way of sourcing.

To keep the focus on the budget with sustainability, we suggest that you look at off-site manufacturing: buildings that are prepared before delivery to the site, factory and provide large savings on the costs of construction during the periods of build reduced and disruption of the site: systems such as shell's Cabinco MPL buildings. Newspapers are factory of precision designed and then delivered to the site ready for fast and precise, to an individually designed sustainable building construction.

More the proportion of wood in your new school building, most likely a fully recyclable building envelope. Wood does not have to be restricted to just the outer skin which gives the appearance of sustainability, but may extend to interior walls, floors, Windows, doors, roof and same structure the final roofing material through such options as the Cedar shingles. A solution of solid wood.

Checklist for sustainable buildings

Carbon footprint

Carbon footprint is an assessment of the impact of the building on the school environment. It focuses on all aspects of the processes involved in the delivery of your solution built in detail and includes such things as the energy used in manufacturing, where this energy source, if it is renewable; energy used in the transport of materials, including used fuel; energy of phase of construction and waste; energy service; and, finally, the end of the energy of life - or step in the case of wood that can be reused as fuel.

Research shows that wooden buildings have the lowest carbon footprint of the life of all.
