16 September 2005In his speech to the United Nations General Assembly in New York on Thursday, South African President Thabo Mbeki slammed the inadequate progress in implementing poverty-reduction goals set by the world body in 2000, and criticised the lack of UN reform. In this he added his voice to similar comments by the leaders of India and Brazil.Mbeki described as a “miserable performance” the failure of UN member countries to agree on a comprehensive package of reforms.“In truth we have not made the decisive progress we thought we would make with regard to the critical issue of the reform of the United Nations,” he said. “We have therefore had no choice but to postpone to a later date the decisions we should have made.”Speaking on the second day of the world’s largest gathering of heads of state and government, the president pointed to the Millennium Development Goals, which include an undertaking by rich countries to commit 0.7% of national income to development aid to poor nations by 2015.“Our approach to the challenge to commit and deploy the necessary resources for the realisation of the Millennium Development Goals has been half-hearted, timid and tepid,” Mbeki said.“We firmly believe that the reason we have not made the progress we should have, during the last five years, is precisely because we have not as yet achieved what the outcome document described as ‘a security consensus’.”Mbeki was referring to the UN reform package approved by the UN earlier this week.“We have not achieved that ‘security consensus’ because of the widely disparate conditions of existence and interests among the member states of the UN, as well as the gross imbalance of power that define the relationship among these member states.“It is the poor of the world whose interests are best served by real and genuine respect for the fundamental proposition that we need the ‘security consensus’ identified by the outcome document. The actions of the rich and powerful strongly suggest that these are not in the least convinced that this ‘security consensus’ would serve their interests.“Thus they use their power to perpetuate the power imbalance in the ordering of global affairs. As a consequence of this, we have not made the progress of the reform of the UN that we should have.“Because of that, we have the result that we have not achieved the required scale of resource transfer from those who have these resources, to empower the poor of the world to extricate themselves from their misery.“Simply put, this means that the logic of the use of power is the reinforcement of the might of the powerful, and therefore the perpetuation of the disempowerment of the powerless.“This is the poisonous mixture that has given us the outcome that will issue from this Millennium Review Summit to the peoples of the world. We should not be surprised when these billions do not acclaim us as heroes and heroines.”SouthAfrica.info reporter
Five years ago, I completed a green remodel of my family’s home. We included green features like solar electric panels, a solar hot water system, recycled lumber, Trex decking, and many other green products. But since the remodeling work was completed, we’ve had years of consistently high propane bills, and I began to question whether my house is actually any greener or more sustainable that the average home.For the past three years, our home has consumed between 1,300 and 1,500 gallons of propane per year. That’s “sustainable,” all right — for the oil industry! I have since learned that while using recycled, reclaimed, and renewable products is a noble green building objective, it’s more important to produce an energy-efficient, durable, healthy building that conserves water. Once that’s done, you can supplement your energy with renewables and fill in with as many green products as you like.An energy auditFrustrated by our high energy bills, we hired Balance Point Home Performance Contractors to test our home and help devise strategies for reducing our energy use. These energy auditors performed a blower-door test to determine shell leakage, used infrared thermography to locate leaks, calculated the required heating and cooling loads according to Manual J from the Air Conditioning Contractors of America (ACCA), tested the safety of our combustion appliances, and measured the actual efficiency of the heating and cooling systems.When we remodeled our house, we had chosen to install a radiant floor heating system. Although it was more expensive than other heating systems, it was supposed to be more comfortable and more energy efficient. The radiant tubing was installed in the joist bays below our subfloor. The HVAC contractor chose the less-efficient method of hanging the tubing in the bays instead of stapling it up to the subfloor with heat transfer plates. The contractor also connected the tubing to our uninsulated rim joists, which does a great job of radiating heat to the outdoors. I was advised to use foil-backed fiberglass batts underneath the PEX tubing to reflect heat upward. That’s fine, if you want to keep all the critters warm and cozy in your crawl space — because the fiberglass batts leak heat like a sieve.Furthermore, it turns out that our boiler was considerably oversized. According to the Manual J calculations, our peak heating load is 46,000 Btu/h, but somehow we ended up with a 90,000 Btu/h boiler — twice the necessary size.Fixing these problems won’t be cheapNow, we’re facing the need to downsize the boiler, remove the tubing connections from the rim joists, add heat transfer plates in our joist bays, and install rigid foam insulation under our PEX tubing and at the interior of our rim joists. Then I’ll need to air seal the whole assembly. What an incredible waste of more energy — my energy!The solar hot water system with a tankless water heater as backup has never operated effectively. Solar hot water systems will likely be standard practice someday, but for now they are expensive, and most plumbers aren’t experienced in the correct installation of solar equipment.In retrospect, our tankless water heater was a mistake. Some tankless systems are designed for solar backup, but we mistakenly chose a model that was not designed to accept preheated (solar-heated) water. In general, tankless water heaters provide minimal energy savings, cost about three times as much as a storage unit, and actually waste more water than a storage unit due to the delay in firing. They do, however, produce an endless supply of hot water. But, how is that a green selling point in water-challenged California?Stopping air leaksBuilding shell leakage, in my opinion, are responsible for some of the worst energy losses in most homes. Air leaks are caused by builders’ lack of knowledge and poor workmanship. Air leaks into attics can be easily reduced by using spray foam to seal ceiling leaks and by installing an air barrier on the back side of kneewalls. Air sealing roof vent channels and interstitial cavities is not hard work; it just needs to be done. Reducing shell leakage is probably more important, more effective, and less expensive than the majority of green products on the market.With the 50% California rebate we received in 2004, our photovoltaic (PV) system might appear as a grand success. But it will take approximately 15 years for the PV system to repay itself. It might be a fine investment for those with a big budget, but PV should be way down the list when money is limited. We cannot simply buy sustainability; we must achieve sustainability through careful workmanship throughout the building process.On the positive side, we did make some smart green choices. We used structural insulated panels (SIPs) for our addition, and they have a high R-value and perform well. The Loewen casement windows also function well with minimal air leakage. And we love our interior cabinets, trim, and doors, all made from recycled Douglas fir and cherry certified by the Forest Stewardship Council (FSC).Indoor air quality must be carefully considered when building a new home or remodeling. Tighter homes require a good mechanical ventilation system. Get fresh, filtered air from clean places, not stale air leakage from crawl spaces and attics. Test your home for radon. Test all gas appliances for combustion safety. Use carbon monoxide detectors, and be careful if your garage is attached to the house. Car exhaust and other toxins can leak into your home when it is under a negative pressure.All new equipment needs to be commissionedFinally, don’t assume that any particular building system or mechanical system will automatically be energy efficient. Regardless of the type of equipment you choose, any system can either perform beautifully or perform pathetically. Be sure that any work you do is tested by a home-performance contractor to be sure it performs to energy efficient, healthy standards. I wish I had known that five years ago.— E.

zoom Norway has opened an autonomous shipping test bed in Horten on the Oslofjord, Kongsberg said.The test bed, officially opened on December 6, is the third of its kind in the country and the fourth such approved area in the world.Established to support the growth in the development of new solutions for autonomous maritime operations, the new area is open to both Norwegian and international organizations. As explained, the area is designed to be “a convenient, safe, non-congested space to trial new technology and vessels.”The area is specially designated for autonomous trials by the Norwegian Maritime Administration and the Norwegian Coastal Administration.The initiative to establish the new test bed was undertaken by maritime technology company Kongsberg, the town of Horten, classification society DNV GL, Norwegian Defence Research Establishment (FFI) and the University College of South East Norway.The introduction of the test bed follows the last year’s opening of the world’s first autonomous shipping test bed located on the Trondheimsfjord. Additionally, Norway reached an agreement in October this year to set up a test area for unmanned vessels in the Sunnmøre region. What is more, a test area for projects related to autonomous ships was opened in Finland in August 2017.The test beds in Trondheim and Horten are said to be an important resource for Kongsberg’s ongoing development of technology for projects such as the Yara Birkeland, the world’s first all-electric, autonomous containership, the Hrönn, an autonomous offshore support vessel, and marine robotics technology.These and other autonomous vessel projects are expected to transform many aspects of shipping and offshore operations, by introducing safer, more environmentally friendly and cost-effective modes of transport and working at sea, according to Kongsberg.“With critical developments in maritime autonomy technology and software taking place at Kongsberg Maritime in Horten, the location of the new test bed will support a number of ground-breaking technology projects,” Egil Haugsdal, President, Kongsberg Maritime, commented. “The move towards greater autonomy at sea has the potential to transform maritime operations and while the technology has now been proven, we look towards the regulations. Establishment of these test beds are an important step, as it shows close co-operation between the people making the technology and vessels and the organisations developing the rules that will allow them to operate,” he added.
