The MBDA is responsible for inner city regeneration on behalf of the municipality and will manage the entire project.“It is the city’s premier beach and therefore plays a major role in the tourism package offered by the city. The area has been identified for a much-needed facelift and refurbishment. It needs to be revitalised,” says MBDA chief operations officer Pierre Voges.The development, taking place in phases, will include the redevelopment of the skate park and improved parking facilities. The entire project is scheduled for completion by February 2013, provided there are no budget constraints.The upgrade has been welcomed by the business chamber in the city.“This kind of local government investment in infrastructure and basic services, like cleaning and security, is necessary to support tourism. The work of the MBDA has proven that this kind of investment acts as a catalyst for further private sector investment and confidence,” says CEO of the Nelson Mandela Bay Business Chamber Kevin Hustler.Better security, lightingThe King’s Beach area stretches from the super tubes at Humewood to the McArthur Swimming Pool.The plan for King’s Beach is to retain much of its former character, but improve the security, lighting and landscaping in the area.“It is hoped that the end result will bring about the recreation of one of the jewels in the city’s tourism crown, attracting not only the spending power of outside visitors, but drawing the city’s own residents to enjoy and appreciate the area again,” says MBDA.Once completed, residents and visitors will be able to walk along a 5km route covering the entire beachfront area of Port Elizabeth, from Humewood in the northwest to the beach at Pipe and Flat Rocks in the south and beyond.Starting just after this stretch of beach is Cape Recife Nature Reserve, a coastal reserve which offers more hiking opportunities.Water featuresOne of the main components of the upgrade will be water features. The waterways will be fed by water from an old spring located in the basement of The Beaches apartment building and from storm water run-off.Voges notes that this will be the first time that water from the spring will be put to good use, instead of just being pumped into the sea as was done in the past. The water in the pools will be circulated and cleaned thorough filters and reed beds.In the early 1980s the then city engineers department commissioned a Beachfront Structure Plan to guide development of the beachfront areas from King’s Beach to Cape Recife.The plan identified seven nodes for development between the harbour and Cape Recife: King’s Beach, Humewood Beach, Shark Rock, Pollok Beach, the Beacon, Flat Rocks and Winterstrand.However, only Shark Rock, which includes Hobie Beach and a small portion of King’s Beach, were ever redeveloped according to this plan. After that, the city’s budget was re-prioritised and no more funding was allocated to development of the southern beachfront.Over the years the greater King’s Beach area has become run-down and unattractive, with visitors preferring to spend time at the more attractive Shark Rock Pier and Hobie Beach areas.There’s been little use of the magnificent stretch of unbroken beach area and surrounding property of King’s Beach.Taking it in phasesThe MBDA will handle the development in two phases, with phase two comprising of two stages due to budget limitations.Phase one, set to be completed by March 2012, will cost R10-million ($1.3-million) and will include the development of the water features and all associated infrastructure, pathways, grassing and fencing of the pool areas.Phase 2A, at a cost of R3-million ($384 394), will build on the existing work, adding more paving and greening.The most expensive development will be done during Phase 2B with the planned expansion to the skateboard facility and the redevelopment of the existing King’s Beach car park at a cost of R29-million ($3.7-million). The parking area will have to be re-levelled due to complications with storm water run-off.A later phase of the King’s Beach development will see Marine Drive downgraded from the current high-speed thoroughfare to a road where slower speeds will be encouraged.Traffic will be redirected toward Strandfontein Road to make way for more parking areas along the southbound carriageway.Phase two is expected to start in July 2012.“The construction of phase two will depend largely on the Nelson Mandela Bay Municipality’s budget allocations in the next financial year,” says Voges.Completed projectsThe MBDA launched its latest project, the Donkin Reserve upgrade and Route 67, during Heritage weekend in September 2011. The development includes the extensive use of public art and was done in the form of a walk, taking the visitor from the Campanile at the bottom of Strand Street, to the Donkin Reserve located on Donkin hill in Central.Route 67 pays tribute to the public life of Nelson Mandela and the country’s road to democracy.Close by, the Athenaeum Building in Belmont Terrace has also been restored to its former glory and will now be used as an arts and crafts hub.The Athenaeum and Donkin Reserve upgrade forms part of the agency’s overall inner city regeneration efforts of which the Govan Mbeki Avenue and Parliament Street upgrades were the first. The idea behind these efforts is to draw residents, businesses and tourists back into the heart of the city.There has been renewed business interest in the inner city as a result of the municipality’s regeneration efforts, says Hustler. The Govan Mbeki Avenue upgrade has created a bustling shopping area, but he says there are still some areas of concern with run-down buildings and security.Businesses are also showing interest in the area, with upgrading that has started on the Donkin Terrace houses and plans for this to become a “creative quarter”.The renovation of the old Grand Hotel is in progress and the renovation of the Port Elizabeth St George’s Club building in Bird Street for offices and advocates’ chambers is now complete.Parliament Street, its surrounding streets and the Richmond Hill area are also attracting more business, as a range of new restaurants and coffee shops have opened there.last_img read more

High-Tech Windows with Dynamic Glazings

first_imgThe problem is that when you choose a particular glazing for windows, you’re locked into very specific window performance properties. Tinted glass, for example, not only blocks solar heat gain, but also reduces visible light transmittance–making it harder to see through the windows. Blocking that solar gain may be fine most of the time, but even in warm climates there can be times, in the winter for example, when you’d like to bring in that extra solar heat.This lack of flexibility with the usual materials has led some companies to pursue technologies that would allow glazing properties to change, based either on user preferences or on conditions such as temperature. These are collectively referred to as “dynamic glazings.”There were a number of dynamic glazings being exhibited at Greenbuild. I was already familiar with SageGlass, from Sage Electrochromics. This is an “electrochromic” glazing that is normally clear, but it can be tinted by charging it with a small amount of electric current. When SageGlass is used in an insulated glass unit (with standard clear glass), a user can flip a switch, to tint the glass, dropping the solar transmittance from 62% down to 3.5%. It takes a small amount of electricity, about 0.3 watts per square foot, to switch it from clear to tinted (a process that takes 5-10 minutes), then somewhat less current, 0.1 watts per square foot, to maintain the tinted state. When the current flow is switched off, the glazing reverts to it default (clear) state.SageGlass is available as an (expensive) option with Velux skylights and about a dozen commercial glazing systems. The high cost of SageGlass can be offset to some extent, particularly in commercial applications, by eliminating the need for widow blinds, but it’s still very expensive—$50-75 per square foot.The new dynamic glazing product I saw at Greenbuild was from the start-up company RavenBrick. This is a passive, “thermochromic” glazing that changes from clear to tinted when it heats up, such as in bright sunlight. While SageGlass is a metallic coating on the glass, like common low-e coatings, RavenBrick uses an organic material sandwiched between two layers of glass. The actual thermochromic material is only eight microns thick.Clear in its normal state, when the RavenBrick coating is heated up it darkens to allow only 8% light transmission. The idea is that during a hot sunny day, the glass will heat up and activate the thermochromic material, blocking most of the sunlight, while on a cooler or cloudy day, the glass will remain clear. A big advantage is that it doesn’t take any electricity to activate or maintain the tinting, as is necessary with SageGlass, but the down side is that it isn’t controllable by building occupants.There may be times when you want sunlight in the building or views to the outdoors even when significant heat gain will occur. Also, there may be some weird results if there’s a shadow on a portion of a window, resulting in only part of the glass being darkened.The company claims that the product will become available in March 2010, and they are providing prototype glazing for an installation at the National Renewable Energy Laboratory in Golden, Colorado. As with SageGlass, RavenBrick will sell product to window manufacturers, rather than producing windows themselves. RavenBrick’s president told me that the cost will be about $25 per square foot—somewhat lower than SageGlass. It could be a great product; I’ll be watching the test installation carefully.I invite you to share your comments on this blog. You can also follow my musings on Twitter. Last week I wrote about one of the innovative building materials that I saw at this year’s Greenbuild Conference in Phoenix (phase-change drywall). This week, I’ll cover a very different innovation from the conference: dynamic window glazing.Windows provide some important functions in houses: admitting natural daylight, allowing views to the outdoors, letting in fresh air, and protecting against unwanted heat loss and gain. How effectively they do all this depends mostly on the glazings (usually glass, but sometimes plastic, or a combination of glass and plastic). Energy performance can be significantly improved by adding multiple layers of glazing separated by sealed air spaces, by using special low-emissivity (low-e) coatings on the glazing, by using tinted glass that blocks unwanted solar heat gain, or by using low-conductivity gas fill, such as argon and krypton, that slows the movement of heat through the space between layers of glass.
