Industry leaders and stakeholders gathered on 7 September at Hyde Park Corner to examine how to accelerate housing delivery and what is currently being

done to fast track the process. Managing director at IHS, Rob Wesselo described how it

has been a 10-year struggle but “the time has come.” For the IHS, the next step is green affordable housing.

Presentations included in-depth discussion of current economic standing in the property sector, which senior economist from Nedbank, Isaac Matshego, described as lacklustre due to the elevation of political and policy uncertainty. He cites the land expropriation bill as one of the biggest concerns in the industry. Myles Kritzinger, deal maker at IHS, unpacked how green affordable homes are already here and it is a market that is leading the way.

Current results show that it is easy to go green as it user friendly and cheaper. Excellence in Design for Greater Efficiencies (Edge) is the developed rating tool for residential properties. Using the tool, the IHS has approved more than 6 500 green units, including more than 2 800 units with preliminary Design Certification.

The first green affordable housing project in Africa is in Ravenswood, Boksburg. Director general of The National Department of Human Settlements, Mbulelo Ntshangana, focused on detailing the role that the Housing Development Agency (HDA) plays, stating that the organisation has curtailed more than 100 mega projects.

In addition, he stated that the organisation can help developers package their endeavours better.

Panel discussions delved into the future of the residential property sector, the impact of social housing and accelerating the delivery of affordable housing through development finance. Speakers during the discussions included Renney Plit, CEO of AFHCO; Carel De Wit, CEO of Indluplace; Leanne Govender, sales manager Affordable Housing Property Finance at Nedbank; Paul Jackson, CEO at TUHF; Alwyn Nortje, senior legal advisor: Group Legal and Contracts from the City of Johannesburg, among others.

The conference was concluded by a cocktail function that gave attendees the opportunity to network and socialise.

Belville’s housing development aims to help address the student accommodation shortage at Stellenbosch University.

Built by property developer STAG African using light steel frame building (LSFB), which reduces construction time and maintenance costs without compromising on quality or key student needs. The developers are confident that it will easily achieve the 20% minimum savings in energy, water and embodied energy required for Edge certification.

The development consists of 200 bedrooms comprising 25 pods of eight bedrooms and two bathrooms that each feed in to a common kitchen area and socialising room.

Grahame Cruickshanks, managing executive for residential at the Green Building Council of South Africa (GBCSA), says that the STAG project is exciting in more ways than one. “This is the first student housing project to be registered for Edge certification in South Africa and is also the first to use LSFB. It’s encouraging to see innovators such as STAG targeting Edge certification and going beyond the defined categories of the rating system to address flexible construction systems, community building and other innovations.”

Sustainability features include an 89% reduction in the cost of heating and cooling of the buildings due to the design, optimal orientation and the nature of the materials used. LSF walls, which were used in the construction, have a mass of only 10% of walls built out of brick and mortar, resulting in significantly reduced truck trips and, therefore, emissions; and 87% of the steel used is recycled.

Building with light steel helps student deficitProperty developer, STAG African, has registered its Tygerberg 3 student housing development in Bellville, Cape Town for Excellence in Design for Greater Efficiencies (Edge) certification.

The use of water and machinery is also reduced during the construction process due to the nature of the materials used, and a grey water system was installed for irrigation.

John Barnard, Southern African Light Steel Frame Building Association (Sasfa) director, says that it is encouraging that an increasing number of developers are recognising the environmental benefits and long-term cost savings of LSFB. “Sustainability with regard to buildings is essentially based on three criteria: social acceptability, affordability and energy efficiency. LSFB rates highly on all three of the sustainability considerations,” he says.

Barnard adds that embodied energy of materials and components used for LSFB is reported to constitute about 20% of the total energy consumption of a 200m² house

The quality of finishes of LSF building is typically better than conventional built structures.

HOW LSFB COMPARES TO BRICKS AND MORTAR

• LSF buildings appear no different to ‘conventionally’ built structures, except that the quality of finishes is typically better with the former. It has found rapidly growing acceptance for ‘affordable’ as well as up-market buildings in South Africa.

• It is a cost-effective building method, with financial savings emanating mainly from considerable time savings to complete building projects, less rework, reduced logistical costs – which are of growing importance due to escalating fuel prices and general construction inflation – and a drastic reduction of rubble on building sites, when compared with the brick-and-mortar alternative.

• LSF building is significantly more energy efficient than heavy construction methods –regarding ‘embodied energy’ of the materials and components, as well as ‘operational energy’ relating to heating and cooling of the building over its design life.

over a 50-year period with the remaining 80% the operational energy.A cursory glance at Tygerberg 3’s physical structure and at its projected environmental statistics reveal that the project fits perfectly into the three criteria described by Barnard.

According to STAG, optimal design is integral to its offering and all residences are constructed in line with community, sustainability, innovation and flexibility principles. Spaces are designed to be flexible and easily modified, enabling the formation of a unique residential identity and accessibility for students with disabilities.

Edge certification in South Africa is provided exclusively by the GBCSA, which leads the transformation of the South African property industry to ensure that buildings are designed, built and operated in an environmentally sustainable way.

When it comes to disposing of the lights once they give in, CFL have a specific way of disposal.

“Most people don’t know this that CFL bulbs and incandescent have a specific way of disposal. LEDs conform to Restriction of Hazardous Substances (RoHS) environmental CE standards therefore making them safer to the environment and creating a sustainable green future,” he advises. CFLs take about 600 years to breakdown into the earth so they cannot be thrown into the bin and into landfill.

LEDs are not filament based or wire based electricity bulbs. They are electronic-based, which means they consume less power and it’s easier to make them light up. They are recyclable and on the inside, is a printed circuit board. They also last longer because they don’t get hot.

“For example, if you touch the old yellow bulb, you’ll get burnt, literally. The CFL, you can get burnt but they are not as hot. If you touch a LED you won’t get burnt at all,” he says.

“New technology is making LED solutions cheaper to implement while being more robust in operations. For the affordable housing market, typical CFL last anywhere between one and three years, while LED lighting fixtures can last if 10 years with little variance in pricing from inception,” Ogle states.

This makes maintenance costs for residence much lower. An added benefit of the low wattage means that circuit breakers and overall installation costs are more affordable allowing for newer technologies to be deployed.

LIGHTING IN PUBLIC SPACESGovernment and various municipalities have adopted the use of energy efficient lighting for street and public lights.

In 2008 the Department of Minerals and Energy proposed a regulation in terms of norms and standards for reticulation services that all street lights must be fitted with energy efficient bulbs. The Illumination Engineering Society of South Africa (IESSA) responded to the draft regulations by suggesting the following rewording, ‘All streetlight systems shall be converted to energy efficient technologies, using light sources with an efficient technologies, using light sources with a luminous efficacy of at least 70lm/W, without reducing the minimum lighting levels beyond those stipulated by the current guidelines as contained in stipulated by the current guidelines, as contained in SANS 10098, Lighting of Public Thoroughfares, Part I and II.’

Although they faced many challenges around the implementation of this due to size requirements of the lights, the use of solar luminaries has been implemented on different roads in Johannesburg such as Paul Kruger Road and Daveyton Road.

BEKA Schréder, manufacturer of luminaires and glass fibre reinforced polyester (GRP) poles, says that technologies are available to significantly improve the energy efficiency of street lighting.

With the birth of Excellence in Design for Greater Efficiencies (Edge), a green rating tool that is specifically for the residential market, going

green affordably is possible. Miles Kritzinger from International Housing Solutions

(IHS) says that it is a market that is leading the way. The sector has seen a few projects that have been awarded green certification, projects such as Candlewood in Boksburg and Fourleaf Estate in Port Elizabeth. The IHS is a real estate investment manager focused on the development and management of residential projects being affordable to the fast-growing middle-income market. It states that it has a growing number of units that meet the Edge criteria and it has set a target of 5 060 green homes. They have a total of over 6 500 units approved ‘to be greened’ investments.

The Design Indaba 10x10 Low-Cost Housing Project, The Butterfly Housing Project and the Cato Manor Green Street retrofit are other examples of affordable housing projects implementing green initiatives. “These demonstrate how

re-thinking our approach to the design of affordable housing projects really can work in our country,” he says.

GOING GREEN ON A SMALL SCALEGoing green can be done in a small or large capacity. For the affordable housing market your approach to going green may be a little different to conventional methods as they can be a little bit pricy.

Eloshan Naicker, green star accredited professional (new building) and Edge-accredited professional and expert from Creative Axis Architects, says that this approach is two-fold.

“Green initiatives can be approached in two ways on affordable housing projects to make them homes and in the greater sense, communities. On a micro scale, simple design and construction methods are easily achievable,” he says.

Things such as appropriate orientation on site to promote natural daylight warms up homes significantly in winter and reduces the risk of flooding.

Page 7: New leads the change - EDGE Buildings · 2020. 8. 13. · november - december 2017 $))25'$%/( $))25'$%/(sa +286,1*

“Encouraging natural ventilation and daylight through the correct window to wall ratios can cool the homes in summer and make interior spaces more liveable. The application of semi reflective or lightly coloured roofing material coupled with insulation to ceiling voids, greatly reduces heat gains in summer and heat loss in winter,” he explains.

Other ways of designing the home to achieve sustainability include insulated solar geysers with electrical backup this ensures that the home will have hot water while reducing the need for electrical water heating. Water can be collected from roof gutters for flushing toilets and watering gardens or in times of water shortages. Low flow sanitary fittings are affordable and significantly reduce the demand on water supply.

Luke Osburn from the Council for Scientific and Industrial Research (CSIR) Built Environment, says that lighting only consumes about 11% of the energy used in a residential environment. “Through conscientious design of the lighting systems, the lighting load can be reduced by more than half,” he says.

He suggests that fluorescent tubes should be used where possible as they use roughly a quarter of the power that incandescent bulbs require to produce the same amount of light.

“Because the fluorescent tubes are more energy efficient than the incandescent bulbs, they also produce significantly less heat which means that a smaller heating, ventilation and air conditioning (HVAC) system is required and less energy is required from the HVAC system to maintain a comfortable temperature and working environment. A variety of fluorescent tubes are available and care should be taken that the most appropriate fluorescent tubes are installed for the given application,” he advises.

Light-emitting diode (LED) lighting can be used throughout the home to save on electricity. LEDs consume less power and thus last longer.

“LED is easier to recycle because they are made with a Restriction of Hazardous Substances (RoHS) substance that makes it easier to dispose. With LEDs you are consuming less power on the grid,” says Fazil Ogle, MD of OPS360.

Normal energy savers uses 11kW, while LEDs uses 5kW. Investing in solar and other means gives you a saving of about 2.5 less kW. “A typical three-bedroomed home that just runs off solar with LED will cost about R30 000 to

R55 000 depending on how you use it. If you don’t use LEDs, it may cost around R80 000 to R120 000.”

GOING GREEN ON A BIG SCALE“On a macro scale, town planning plays an important role in making a community as opposed to another standard housing project,” says Naicker.

Some ways that this can be done is with the inclusion of recreational spaces. These can reduce stress and encourage communal growth. Storm water management across the site reduces the risk of flooding and the water can be collected and used within the recreational spaces or in times of drought.

“Communal recycling facilities and waste management can stimulate job creation and reduce waste going to already stretched landfill sites. Solar powered street lights save on electrical supply and make streets safer,” he says. Locating housing projects close to public transport nodes and efficient movement networks within the communities makes commuting easier and safer.

Matt Jackson from the Johannesburg Development Agency (JDA) says that transit-oriented development (TOD) coupled with affordable housing are bankable. “Simply put, TOD is a city development approach which intensifies and diversifies land use along public transit routes and stations precinct,” he says. He says that the Yeoville suburb in Johannesburg is an area that is doing this well.

In Cape Town, Michael Alton describes a growing trend of heat pump installations.

“The introduction of lower capacity integrated heat pumps (150ℓ) by HydraTherm (compared with competitive brands that use 200ℓ and 300ℓ tanks), is technology that is starting to gain traction in the affordable housing sector in Cape Town. An integrated heat pump is a solution in which the tank (geyser) and heat pump are combined into one unit,” he says.

A heat pump is an energy-efficient water heater that removes free heat energy from the surrounding air and transfers this to the water in your geyser.

Affordable, low capacity domestic heat pumps (3.8kW or less) can be combined with an affordable geyser (100ℓ or 150ℓ) to create an efficient means of heating water. “This will save the occupants of the home 70% of the water heating costs of a traditional geyser element,” states Alton.

Solar panels are gaining traction in a lot of affordable housing projects.

"If we provide thought through homes and communities and educate the community, we can greatly reduce our energy requirements"

FEATURES

CHALLENGES OF GOING GREENThe alternative energy industry is slowly developing in our country, PV panels and solar geysers are becoming more efficient and affordable. “The current cost of alternative energy use impacts on return on investment and does not warrant the installation of these items. This is where innovative financing and public private partnerships funding (PPP) becomes key to overcoming the cost challenges,” says Naicker.

The inclusion of alternative energy can require specialist contractors that impacts on the building programme and logistics and, again, on costs. Naicker says that these factors aren’t all negative as skills development and small and medium-sized enterprises (SMEs) are growing in this sector.

“If we provide thought through homes and communities and educate the community, we can greatly reduce our energy requirements,” says Naicker.

WAY FORWARDThe most important factor is behaviour, educating the public on how the homes and communities are designed. Initiatives around this are also vital to the success of these projects.

“We are still not taking full advantage of green initiatives in affordable housing projects though, the main concern is funding and getting return on investment, these challenges can be easily overcome through innovative financing of projects and the partnership of the public and private sectors,” says Naicker.

Collecting rain water to flush toilets is also a way of being sustainable affordably.

Other ways of designing the home to achieve sustainability include insulated solar geysers with electrical backup this ensures that the home will have hot water while reducing the need for electrical water heating. Water can be collected from roof gutters for flushing toilets and watering gardens or in times of water shortages. Low flow sanitary fittings are affordable and significantly reduce the demand on water supply.

Luke Osburn from the Council for Scientific and Industrial Research (CSIR) Built Environment, says that lighting only consumes about 11% of the energy used in a residential environment. “Through conscientious design of the lighting systems, the lighting load can be reduced by more than half,” he says.

He suggests that fluorescent tubes should be used where possible as they use roughly a quarter of the power that incandescent bulbs require to produce the same amount of light.

“Because the fluorescent tubes are more energy efficient than the incandescent bulbs, they also produce significantly less heat which means that a smaller heating, ventilation and air conditioning (HVAC) system is required and less energy is required from the HVAC system to maintain a comfortable temperature and working environment. A variety of fluorescent tubes are available and care should be taken that the most appropriate fluorescent tubes are installed for the given application,” he advises.

Light-emitting diode (LED) lighting can be used throughout the home to save on electricity. LEDs consume less power and thus last longer.

“LED is easier to recycle because they are made with a Restriction of Hazardous Substances (RoHS) substance that makes it easier to dispose. With LEDs you are consuming less power on the grid,” says Fazil Ogle, MD of OPS360.

Normal energy savers uses 11kW, while LEDs uses 5kW. Investing in solar and other means gives you a saving of about 2.5 less kW. “A typical three-bedroomed home that just runs off solar with LED will cost about R30 000 to

R55 000 depending on how you use it. If you don’t use LEDs, it may cost around R80 000 to R120 000.”

GOING GREEN ON A BIG SCALE“On a macro scale, town planning plays an important role in making a community as opposed to another standard housing project,” says Naicker.

Some ways that this can be done is with the inclusion of recreational spaces. These can reduce stress and encourage communal growth. Storm water management across the site reduces the risk of flooding and the water can be collected and used within the recreational spaces or in times of drought.

“Communal recycling facilities and waste management can stimulate job creation and reduce waste going to already stretched landfill sites. Solar powered street lights save on electrical supply and make streets safer,” he says. Locating housing projects close to public transport nodes and efficient movement networks within the communities makes commuting easier and safer.

Matt Jackson from the Johannesburg Development Agency (JDA) says that transit-oriented development (TOD) coupled with affordable housing are bankable. “Simply put, TOD is a city development approach which intensifies and diversifies land use along public transit routes and stations precinct,” he says. He says that the Yeoville suburb in Johannesburg is an area that is doing this well.

In Cape Town, Michael Alton describes a growing trend of heat pump installations.

“The introduction of lower capacity integrated heat pumps (150ℓ) by HydraTherm (compared with competitive brands that use 200ℓ and 300ℓ tanks), is technology that is starting to gain traction in the affordable housing sector in Cape Town. An integrated heat pump is a solution in which the tank (geyser) and heat pump are combined into one unit,” he says.

A heat pump is an energy-efficient water heater that removes free heat energy from the surrounding air and transfers this to the water in your geyser.

Affordable, low capacity domestic heat pumps (3.8kW or less) can be combined with an affordable geyser (100ℓ or 150ℓ) to create an efficient means of heating water. “This will save the occupants of the home 70% of the water heating costs of a traditional geyser element,” states Alton.

Solar panels are gaining traction in a lot of affordable housing projects.

"If we provide thought through homes and communities and educate the community, we can greatly reduce our energy requirements"

CHALLENGES OF GOING GREENThe alternative energy industry is slowly developing in our country, PV panels and solar geysers are becoming more efficient and affordable. “The current cost of alternative energy use impacts on return on investment and does not warrant the installation of these items. This is where innovative financing and public private partnerships funding (PPP) becomes key to overcoming the cost challenges,” says Naicker.

The inclusion of alternative energy can require specialist contractors that impacts on the building programme and logistics and, again, on costs. Naicker says that these factors aren’t all negative as skills development and small and medium-sized enterprises (SMEs) are growing in this sector.

“If we provide thought through homes and communities and educate the community, we can greatly reduce our energy requirements,” says Naicker.

WAY FORWARDThe most important factor is behaviour, educating the public on how the homes and communities are designed. Initiatives around this are also vital to the success of these projects.

“We are still not taking full advantage of green initiatives in affordable housing projects though, the main concern is funding and getting return on investment, these challenges can be easily overcome through innovative financing of projects and the partnership of the public and private sectors,” says Naicker.

Collecting rain water to flush toilets is also a way of being sustainable affordably.
