Mudballs Clean Up

Posted: February 25, 2010 by Jimmy Lee, Category:Uncategorized

Recently, there is different kind of activities in Malaysia where people start promoting a technology called Effective Micro-organism (EM) technology. This is mainly used to treat greywater, minimise odour in septic tanks, remove sludge from drains and improve recycle water.

Last year, there is an environmental biomediation project & awareness campaign in Penang named “One million apologies to mother earth”. The idea was to organise an event of making one million EM mud ball and throwing them into various heavily polluted rivers in Penang, Malaysia in a single day.

The concept of EM Technology was developed by Japanese horticulturist Dr. Teruo Higa, from the University of the Ryukyus in Okinawa, Japan. Dr. Higa claims that three groups of micro-organisms exist: ‘positive micro-organisms’ (regeneration), ‘negative micro-organisms’ (decomposition, degeneration) and ‘opportunist micro-organisms’. In every medium (soil, water, air, the human intestine), the ratio of ‘positive’ and ‘negative’ microorganisms is critical, since the opportunist microorganisms follow the trend to regeneration or degeneration. Therefore, Dr. Higa believes that it is possible to positively influence the given media by supplementing with positive microorganisms.

Japan had used EM Technology to clean up more than one hundred heavily polluted rivers over the last 20 years. EM is a proven technology in environmental remediation and all the rivers that have been treated with EM in Japan have also managed to resuscitate aquatic life, bringing back all fishes and other water life forms and aquatic plants. The most famous project in Japan is the cleaning up of the Seto Inland Sea.

EM has also been employed in 130 countries in many agricultural applications and also in the production of several health products in South Africa and the USA.

Hope this technology can be promoted more around to help improve the water quality in any polluted rivers or close system ponds in an environmental friendly way.

Here is a video on how to make mud balls.

Are you watching the Olympics?

Posted: February 23, 2010 by Kaye, Category:Sustainability

Are you watching closely? Turns out, the new take on the gold, silver and bronze medals is more than just a funky new shape. In an effort to reduce electronic waste, each medal was made with a tiny bit of the more than 140,000 tons of e-waste that otherwise would have been sent to Canadian landfills. And that’s not the only eco-friendly thing about the 2010 winter games.

The Olympic Village in Vancouver has received LEED certification. According to The Vancouver Sun, “The athletes’ village in Vancouver’s southeast False Creek can now be called the greenest community in the North America - possibly the world - Mayor Gregor Robertson said Tuesday morning, as he announced the entire neighbourhood had received a certification from the U.S. Green Building Council.”

 

Yesterday, “Platinum certification was awarded to the $1-billion, 32-hectare South East False Creek neighbourhood development project based on a variety of factors including its proximity to the downtown core, affordable housing, green buildings and habitat restoration. The Olympic Village is the second development in the world to receive Platinum certification.”

Some of the examples of the design elements of the buildings throughout the athletes’ village are green roofs, cisterns to catch rainwater, passive solar design, upgraded insulation and windows as well as carpets and paint with low or no VOC.

When the announcement was made on Tuesday, USGBC chair Tim Cole called the athletes’ village a “remarkable example” of what is possible.

Lance Hosey, in his Op-Eco blog, looks over the sustainability claims by Olympic organizers that the Vancouver games are “the greenest games ever.” Supposedly, various forms of waste mitigation and energy efficiency will take down the games’ carbon output by 15 percent. But the land-grading methods used to make ski slopes at Whistler are among the most permanently destructive. And, of course, the organizers can’t help it if the air travel involved in bringing people to the games amounts to the annual belchings of 30,000 cars.

Should Ireland go nuclear?

Posted: February 17, 2010 by Cormac, Category:Sustainability

With climate change firmly on the agenda of governments around the world, many countries are looking to invest further nuclear energy as a way to reduce their carbon emissions. This begs the question: should Ireland go nuclear? This simple question can provoke extremely heated debates in Ireland. The last time Ireland considered nuclear power was in the late 1970’s. Thousands of people descended on the proposed site in Carnsore Point in Co. Wexford for week long “protest festivals”. The plans were scrapped. Yes, Chernobyl was one of the biggest human tragedies in history but there is simply no comparison between the nuclear reactor at Chernobyl and a modern nuclear reactor. At the moment Ireland imports a significant amount of electricity from the UK and which has numerous nuclear power stations.

I believe Ireland needs to have a reasonable and logical debate on what our long term energy source will be. Do I believe Ireland should go nuclear? Absolutely not, but in my opinion Irish people are vehemently opposed to nuclear power for all the wrong reasons. Is there a single nuclear power station in Saudi Arabia? Unsurprisingly the answer is no. The Saudi’s sit on the world’s largest oil reserves so they have had no need for nuclear. The west coast of Ireland on the other hand has some of the best wind energy potential in the world. Ireland has roughly 2% of the EU’s land mass but about 6% of the wind energy potential. This makes Ireland one of the richest countries in the world in terms of wind energy potential per capita.

The ambitious “Spirit of Ireland” project proposes to build a massive network of wind turbines and hydro energy reservoirs along the west coast of Ireland to not only meet the energy needs of Ireland, but to also export electricity to the UK and mainland Europe. The key principle behind this project lies with the hydro energy reservoirs. These are basically large water reservoirs built on the top of hills or cliffs. The wind turbines are used to power water pumps which will pump water up to these reservoirs. When the water is released from the reservoir it flows down hill through hydro electric turbines to generate electricity for the country. The basic theory is to convert wind energy to hydro energy to electricity.

The major disadvantage of wind energy alone is its unreliability. The wind might blow when you don’t need it and might not blow when you do. The major advantage of using hydro energy reservoirs along with wind turbines is that you will always have a constant supply regardless of the weather! Wind energy alone would never be reliable enough to meet the countries needs. Currently Ireland has only one hydro energy storage reservoir facilities at Turlough Hill Co. Wicklow. Spirit of Ireland envisage building many more of these along the west coast of Ireland.

With natural resources like this why would we even consider nuclear…

Visualisation

Posted: February 12, 2010 by Phil, Category:Sustainability

I recently read about the Environment 2.0 Exhibition at FutureEverything 2009. In particular two exhibits made a point of highlighting sources of Carbon Emissions in ways that encourage people to think of the impact they could be having on the environment.

The first was Aaron Koblin’s Flight Patterns

It is accepted that air travel is a major source of carbon emissions and will have to be tackled by governments who are aiming to cut emissions to meet increasingly ambitious targets and shows the reality of the current dependence on air travel by animating the flight paths of thousands of aircraft over US airspace in a 24 hour period.

The second was HeHe’s large-scale environmental installation Nuage Vert (meaning Green Cloud).

A laser image was projected on to the cloud of vapour as it spewed out from a power plant chimney (“the ultimate icon of industrial pollution”) over Helsinki with the aim of making the local population consider the emissions from the plant the relationship to their own power consumption. The image shape and size was adjusted according to power consumption and people in the local area were encouraged to reduce electricity usage while the image was projected so that “the green cloud could grow”.

These projects show us how the everyday activities of people are affecting the environment by presenting the effects of our actions in a visual way that anyone can appreciate. In much the same way, IES is constantly working to present solutions to these issues in a way that people can fully appreciate and use to improve building design so that emissions are lowered in future.

An Integrative Design Process (IDP) is a collaborative approach to building design which places a strong emphasis on cross-team integration throughout the development process in pursuit of a ‘whole building’ holistic design. But where does it start and what does it really mean? How can the range of IES <VE> software tools be used to assist in the design process?

In conventional building design a project develops through a strict and rigid chain of milestones and hand-offs e.g. owner requirements to architect, architect’s concept to structural engineer, structural design to MEP engineer etc.

This conventional process means that key members of the design team are often excluded from the initial planning stage, and with the lack of their expert knowledge and insight the project can progress down the wrong path for a significant period of time before serious underlying problems are identified. This leads to inefficiency; higher capital costs, time delays, over-sized HVAC etc.

With an Integrative Design Process (IDP) all key members of the multi-disciplinary design team are included at the very beginning of the planning stage, from the initial conception of the building itself. In this way all major design decisions can be carefully considered in relation to other disciplines right from the outset. This avoids abortive work resulting from single-minded decisions and increases overall project efficiency.

So where does building performance analysis fit-in?

The IES <VE> platform provides a unique set of analysis tools that allow building performance analysis to be used throughout every stage of the project, from concept to completion. An experienced <VE> engineer becomes an integral member of the IDP team and can really help drive the design to meet aggressive sustainability targets and objectives.

Let’s look at the lifecycle of a typical project and how the <VE> could be used at each stage:


 







Concept: VE-Ware and VE-Toolkits used with Google SketchUp ‘massing’ models of various design options and iterations to determine performance characteristics: climate metrics, optimum site orientation, daylight feasibility, ballpark energy estimates etc.

Scheme: Findings from Concept analysis used to select the ‘optimum’ design solution which is then progressed to schematic stage. VE-Toolkits and VE-Gaia used to enhance the basic design i.e. optimize; shading, building envelope, daylight, energy etc

Detail: Enhanced model from Scheme design is driven more aggressively with VE-Gaia and VE-Pro to extract further energy savings i.e. optimize; HVAC plant selection (right-sizing), electric lighting dimming control strategy, zone set-back temperatures, boiler/chiller optimum start/stop etc.

Construction: Findings from Detail analysis input to Construction Documentation and the optimized Detail model is then
updated with ‘As-Built’ information. This ensures that the specified design has actually been installed i.e. do pressure test results match the design infiltration rates, are installed plant efficiencies and SFP’s as per the MEP spec, has the glazing data specified(u-value, SC etc.) actually been installed? Comparative VE-Pro analyses conducted to benchmark Design vs As-Built

Commissioning: Findings from Construction comparison used to drive Quality Assurance (QA) checks in order to identify areas that are not installed and performing as per design. Detailed <VE> room loads can be used to assist in production of Commissioning Documentation and for balancing calculations for duct and pipework systems.

Operation: 6months to 1yr after completion recorded BMS readings can be compared against the As-Built Construction model. Comparative analysis is used to determine areas of the building and associated HVAC plant which are not performing as per design. The building FM team continues to monitor BMS vs Model readings, making site changes where necessary to ensure that the building operates at optimum performance.

This example illustrates how the building performance analysis can be used to fully support an Integrative Design Process. By utilizing the unique four-tiered <VE> approach (VE-Ware, VE-Toolkits, VE-Gaia and VE-Pro) there is an analysis tool for every occasion which can be closely aligned with the sustainability objectives of the project in order to realize the maximum potential.

Through the use of the Google SketchUp based conceptual <VE> analysis tools a building’s energy and carbon footprint can be optimized from the initial outset of the project, before it has a chance to progress down a wrong path. By getting involved early more aggressive energy and sustainability targets can be met and realized such as LEED Platinum, Estidama 5-Pearl, BREEAM Outstanding etc

But the use of performance analysis tools at concept stage alone is not enough on to reach these higher objectives. Aggressive targets mean that an aggressive modeling strategy must be used an continued throughout the project from concept to completion. This is the only way of designing buildings that are truly ‘green’ and is the only way of taking the Integrative Design Process to ‘Infinity and Beyond’.
