Who’s Going to Wear the Green Tights?

Gateway Hotel - Umhlanga

Have you ever witnessed one of those moments at a glittering event, where the company envoy ostentatiously hands over the enormous polystyrene dummy cheque to the suitably grateful charity representative. The cameras flash, the recipient’s knees bend a little, the company boss swells and flashes a self-satisfied smile. People clap and everyone swoons in awe at the selfless generosity of business. Onlookers declare: “They do have a heart.” And “It’s not just about the money.” Let’s not pretend that business doesn’t need positive affirmation from the community. Face it; we all like a good pat on the back.
Which brings up a growing trend in the world that has found its feet in South Africa. Green Buildings. If ever there was a way of scoring points with the community, government and those with not only green fingers but whose superhero sports green underwear – the environmentalist, this is it.  IF you’re a land lord don’t knock it, because something’s in it for you.
Recently this was demonstrated in the latest extension to that Mecca of upmarket shopping, Sandton City. A splendid dome graces the new Protea Court. This crowning expansion, involves interior refurbishments and 30,000sqm of new retail space. The Protea Court roof has been created with a product called Texlon, which is made up of multiple layers of foil known as ethylene-tetra-fluoro-ethylene (ETFE) it’s so green it could be mistaken for peas.
“Texlon is an innovative technology used worldwide but has been used for the first time in South Africa at Sandton City,” affirms architect Tia Kanakakis from MDS Architecture. “It was selected as a suitable roofing material as it is lightweight and an environmentally-friendly climatic envelope”.
Kanakakis pointed out excitedly: “The ETFE material is unique in that it does not degrade under ultraviolet light or atmospheric pollution.” The material doesn’t harden yellow or deteriorate. Furthermore, as the surface is very smooth and has anti-adhesive properties, the envelope self-cleanses in rain.” For Sandton City this means going Green and they are being richly rewarded already. Sandton City Manager Sharon Swain was able to announce the arrival of international names like Dumond, Inglot, Carlo Pignatelli, Miguel Vieira and Kurt Geiger to the centre.

Of course Green buildings aren’t new. Twenty-one years ago two initiatives were launched which were foundational to  establishing the concept of energy-efficient buildings and green building: BRE (British Research Establishment) released BREEAM, and BREEAM became the basis for a host of other rating tools including LEED in the US and the much talked about Green Star in Australia.
What about the landlord cost/tenant benefit scenario?  Investor’s landlords may well ask what’s in it them, surely more of a good old pat on the back? The Australian Financial Review explored the importance of green-star ratings, which basically determine how Green a building is, in attracting tenants to buildings. When looking for leasing locations tenants are now demanding at least a four star rating. In Australian cities the demand for the now-coveted green buildings is driving up costs in refurbishing and retrofitting older buildings. Greener adds value and demands higher rents.
According to property investment analysts IPD, Green Star buildings are outperforming non-rated buildings on a financial basis by a significant margin.
Here in South Africa,  Llewellyn van Wyk, Editor at Large for Green Building South Africa writes: “Ultimately I believe green building is in the national interest, and should be an issue driven by Government: for this reason, I strongly supported the establishment of a Part X “Environmental Sustainability” to the South African National Building Regulations and look forward to it being populated with the full range of deep green building imperatives in due course.”

The world-class, high-tech design of the Durban ICC building itself incorporates green elements such as large glass facades for natural lighting, reducing the need for artificial lighting, and energy saving escalators which only activate when stepped on. In addition, the Centre utilises energy-efficient air-conditioning systems which build up ice overnight, which is used to cool the building the following day. Indigenous landscaping is a feature of the Durban ICC, with the majority of plants local to Kwazulu-Natal, limiting the reliance on irrigation. The Durban ICC’s water use profile is low for a building of its size. The installation of sensor taps in the bathrooms prevents water waste and even its toilets have been converted to a more efficient water usage system.

In the US the Green standard is held up by LEED, which has not been without its squabbles:  Henry Gifford has made his living designing mechanical systems for energy-efficient buildings in New York City. And he admits the (LEED) program has popularized the idea of green building: “LEED has probably contributed more to the current popularity of green buildings in the public’s eye than anything else. It is such a valuable selling point that it is featured prominently in advertisements for buildings that achieve it. LEED-certified buildings make headlines, attract tenants and command higher prices.”
 

By means of counter point Ben Ikenson reports on the current controversy embroiling LEED and hence whole Green Building bureaucracy in the US:”But for years, Gifford has been a tenacious and vocal opponent of LEED, claiming that the program’s “big return on investment’ is more a matter of faith than fact, and that LEED simply “fills the need for a big lie to the public.” Last October, Gifford filed a class-action lawsuit for more than $100 million against the USGBC, accusing the non-profit of making false claims about how much energy LEED-certified buildings actually save and using its claims to advance a monopoly in the market that robs legitimate experts — such as himself — of jobs. We may ask ourselves if we need this in South Africa.
Back to the benefits, conventional wisdom has it that not only does the environment benefit from the carefully considered construction that goes with Green building, but that people are generally happier and more content working or living in Greener buildings. Comments Dr Suzan Oelofse, IWMSA Central Branch Chairman, “The environmental benefits derived from green buildings can further be enhanced by including waste minimisation and recycling principles in this type of environment.”
Further to this, Oelofse believes that Green buildings should be orientated in such a way as to reduce the heat load and to optimise shade and thereby enabling the use of more energy efficient lighting systems and air conditioning.  This makes economic sense in the light of on-going increasing Eskom electricity costs and it makes sound economic and environmental sense to use renewable resources and to become as energy efficient as possible.
It seems the devil may be in the bureaucracy and that making buildings greener may require state rather than private regulation if the LEED struggles are anything to go by. But there are clearly many practical and financial benefits to Greening up the workplace. Besides there’s nothing quite like that warm approval that comes from cosying up to a superhero or heroine in green tights.

Green Construction – What’s left after the hype?

Green OfficesBack in 2011 regulations were put in place that officially launched South Africa into the world of green buildings. Of course there had been those who had pioneered a path years before but it’s since then that South Africa has chosen to walk in step with the much of the world on the green buildings front.  In fact between the 16th-18 of October this year will see Cape Town play host to the “Green Leaders for the World GBC Congress” at the 6th annual Green Building Convention.

Internationally much of the hype has died down and a vast body of people in the industry are knuckling down and getting on with the business of building better quality buildings. Many of those previously sceptical players in the building industry have realised that Green construction isn’t all that different from the conventional kind. Both need to be vigilantly organized and both need skilled labour to be brought to the table. The difference is that conventional construction doesn’t take the welfare of the environment into account nearly as much as green construction does. A building with certain green guidelines will even see construction of mechanisms whose sole purpose is to greatly reduce the overall impact the building has on the environment. Conventional construction often doesn’t have any such additional mechanisms.

Green guidelines have the wherewithal to demand that a building receive a given portion of its energy from solar or wind power sources. The infrastructure for such energy delivery would have to be put in place during the early stages of construction.

Inevitably the issue of construction costs of green buildings surface regularly, but these have come down significantly, making green buildings more affordable. Dr. Prem C. Jain, Chairman – Indian Green Building Council says that in India the construction costs of a green building which is about 3-5 per cent higher for Platinum rated green building than a conventional building, the incremental cost gets paid back within 3-4 years with substantial reduction in operational costs.

The conventionally held view is that the initial or capital cost of energy efficient and green buildings is higher than that of other buildings. However, it is well established in studies done in the US, UK, Australia and India that when considering the total costs over the life of a building, including capital and operational costs, energy efficient and green buildings are typically more economical than conventional buildings. Specifically, the Intergovernmental Panel on Climate Change (IPCC) has noted that the energy consumption in both new and existing buildings can be cut by an estimated 30 to 50 per cent without significantly increasing investment costs with proven and commercially available technologies. The IPCC further notes that this potential for greenhouse gas emission reductions from buildings is common to developed and developing countries.

images (2)Some construction that follows international green guidelines merely involves using the most efficient equipment possible. Take central air conditioning for example; previously used units weren’t nearly as efficient as many of the units currently available. Certainly, a building could still be fitted with a less than efficient unit. Green guidelines, though, would most likely stipulate that the building be equipped with an efficient Energy Star compliant unit. Measures would have to be taken to ensure no leakage of heat from the building. A unit working overtime to keep a building at a desired temperature would defeat the whole purpose of getting an efficient unit in the first place. The best way to make sure heat doesn’t easily escape from, or enter into the system, is to make sure the building is sealed and the ducts don’t leak, which is best accounted for during construction- which is the whole point.

Coming back to South African standards: in 2011 government in South Africa put forward the National Building Regulations, SANS 10400 which includes requirements for energy usage in buildings. Now mandated, SANS 10400 is mandatory on all new buildings and major renovations requiring building plan approval.

Energy regulations such as SANS 10400 are important components in energy efficiency of buildings, and energy use equal to or less than that of SANS 10400 is also a minimum requirement for a Green Star SA rating. Extra points are then awarded in the rating system for exceeding the minimum requirements of SANS 10400X. However, Green Star SA goes beyond the requirements of only energy efficiency, addressing other environmental and human health impacts of buildings.

green-building1Furthermore, in its current form, SANS 10400X can only be applied in the design of new buildings and major renovations, and does not specify requirements for the operation or “in-use” phase of buildings – whereas Green Star SA rating tools are being developed for the operation or “in-use” phase of buildings.

According to the Green Building Council of South Africa (GBCSA), an independent body, the country has seen a massive increase in the Green Star SA rating of buildings. Based on the Green Building Council of Australia’s Green Star rating system, it is the official green certification measure for buildings in South Africa, authorised by GBCSA. The first few examples of Green Star rated building in South Africa were; the Nedbank phase-two head office in Sandton;  Xenprop’s Ridgeside project in Umhlanga,  The Villa Mall, in Pretoria and more recently Standard Bank’s Rosebank Office. Many more have followed.

Green guidelines are about trying to save energy and resources, with the ultimate goal of saving the environment. Towards that end, every little bit helps. The sample guidelines above are some of many new initiatives in the construction industry, many more come on to the table as this process rolls out. Time will tell how many were constructive and what failed to make an impact in drive for sustainability and the reduction of the carbon footprint.
