Eskom and CTICC energy saving initiative sheds light on energy consumption
Real-time energy consumption meter readings help businesses use energy sustainably and reduce their carbon footprint.
30 November 2009: Eskom has embarked on an energy saving initiative known as ‘Measure 2 Manage’, which will measure energy consumption in real-time from 30 November to 7 December, 2009, during the pre-draw and final-draw activities taking place at the Cape Town International Conference Centre (CTICC).
“Eskom’s energy supply is still severely constrained and future demand is predicted to exceed supply unless energy consumers reduce their consumption. With the local commercial property sector currently consuming up to 16% of Eskom energy output, commercial properties need to find ways to reduce their consumption not only in the long term but also in the immediate term,” says Nosipho Maphumulo, General Manager, Energy Efficient Demand Side Management (EEDSM).
Substantial cost-savings can be achieved by this sector by implementing energy efficiency measures and being energy efficient has the added benefit of reducing the sector’s environmental impact due to the associated reduction in carbon emissions.
Energy consumption is measured in kilowatt hours (kWh), and it is estimated that 1kWh amounts to a power station emitting 1.03kg of carbon. By reducing the energy consumption of their properties, owners are contributing towards a reduction in carbon emissions.
While there are many energy efficient technologies and adaptations available to this sector, property owners often find it difficult to decide on the best approach for their business, especially when weighing up the initial outlay cost against cost savings achieved as a result of energy savings.
As an industry leader in sustainability CTICC is committed to transforming the events industry to one that is socially, economically and environmentally sustainable. According to Chief Executive Officer, Rashid Toefy: “CTICC is continually thinking of new and innovative ways to implement sustainable initiatives throughout the centre and to encourage event greening”. CTICC is one of the only convention centres in Africa that has had its processes certified according to the internationally recognised systems standards ISO 9001 (Quality Assurance), ISO 14001 (Environmental Management) and OHSAS 18001 (Occupational Health and Safety).
In light of this, the CTICC has given Eskom permission to install 36 meters and modems over the said period to monitor the centre’s energy consumption in real time. This data will also be translated into environmental information, made accessible for viewing via an online energy dashboard, and updated every 60 seconds.
“We are excited to partner with Eskom on this initiative to monitor and reduce our energy consumption” said Toefy. Toefy added that through a concerted effort of switching off unnecessary plant and equipment during December 2008, the centre made a significant saving on electricity, which goes to show the difference that can be made if one is cognisant of how to reduce your carbon footprint.
In addition to being able to monitor and translate energy consumption in real time and making this information easily accessible to external parties, the remote meter reading system can also isolate and monitor various rooms or sections of a building making it even more practical for businesses to find ways to curb energy consumption.
At the CTICC the data loggers will monitor the energy consumption of the various areas being used for the pre- and final-draw activities, namely:
- The admin, coffee shop and registration areas
- The lights for halls one, two, three and four
- Auditoriums one and two
- The east and west ballrooms
- The Jasmine, Stralitzia and Marimba restuarants
- Incomers one and two
With the information collated from this event, the CTICC and Eskom will be able to review the centre’s energy consumption peaks and patterns on a minute-to-minute, hour-to-hour or day-to-day basis, in order to make recommendations on how to curb it for future, similar events.
By visiting the project site: www.measure2manage.co.za, interested parties will have access to: the CTICC’s energy consumption, carbon emissions and energy demand over the draw period, as well as energy saving tips and links to further energy saving information. Visitors to the site will also have the option of registering for periodic energy saving email alerts.

Some helpful commercial property energy saving tips:
|
- Heat pumps:
A simple and effective technology for the lowering of electricity usage in commercial properties is the deployment of heat pumps. Heat pumps use the reverse cycle of a refrigeration utility to heat water and can save up to 66 % of energy consumption. An additional benefit is that the cooling cycle of heat pumps can be utilised to simultaneously cool a portion of, or an entire building.
- Lighting:
The following steps can be taken to improve the energy efficiency of an organisation’s lighting:
-
Switch to energy efficient lighting such as T5 fluorescents . Also replace magnetic ballasts with energy efficient electronic ballasts.
-
Clearly label light switches so that employees know which switches control which lighting zones. If they know where to switch off, they’ll be more inclined to do so when they leave an area unoccupied.
-
Go light on colour - choosing lighter colours for ceilings, walls and surfaces helps reduce the amount of artificial light needed for a building.
-
Install occupancy sensors - occupancy sensors control lighting based on occupant detection. These can be used to control lighting in intermittently occupied areas such as meeting rooms, toilets and print rooms.
-
Deploy daylight sensors - daylight sensors can brighten, dim or even switch off lights according to natural light levels as they change throughout the day, in turn reducing operating and energy costs.
-
Use programmable control systems - these systems can switch off lights automatically or step-down lighting levels for night time security or reduced occupancies.

Eskom and CTICC energy saving initiative sheds light on energy consumption
Real-time energy consumption meter readings help hospitality establishments intelligently control power consumption
30 November 2009: Eskom has embarked on an energy saving initiative, ‘Measure 2 Manage’, which will measure energy consumption in real-time from 30 November to 7 December, 2009, during the pre-draw and final-draw activities taking place at the Cape Town International Conference Centre (CTICC).

During economic downturns, the hospitality industry in particular is compelled to trim its operating costs without compromising productivity or the quality of guests’ comfort. Substantial cost-savings can be achieved by this sector by implementing energy efficiency measures. Being energy efficient has the added benefit of reducing the sector’s environmental impact due to the associated reduction in carbon emissions.
While there are many energy efficient technologies and adaptations available to this sector, property owners often find it difficult to decide on the best approach for their business, especially when weighing up the initial outlay cost against cost savings achieved as a result of energy savings.

The systems have already been installed in certain five star hotels in the Western Cape including the One and Only, Westin Grand, Mount Nelson and the Table Bay with notable results. One of the hotels commented that within a four month period, a 30% saving had been made on their energy demand (or kVA) reading and the systems had paid for themselves already.
At the CTICC the data loggers will monitor the energy consumption of the various areas being used for the pre- and
final-draw activities, namely:

Some useful energy saving tips for the hospitality industry:
|
|
Most hotels and lodges spend up to 35% of their total operating costs on energy. Significant amounts of energy can be saved by applying the following efficiency solutions:
- Heat pumps: By using a heat pump instead of a conventional resistance heating system, establishments can save between 40 – 60% of their energy costs. Heat pumps can also use the heat extracted from the air conditioning systems to heat up water.
- Energy efficient shower heads: By switching to energy efficient shower heads, water usage can be reduced by 30%, in turn substantially cutting water bills.
- Energy efficient lighting: Replace incandescent light bulbs with Compact Flourescent Lamps (CFL’s), they last six times longer, use 80% less electricity and are available in a variety of shapes and sizes which can blend in easily with the décor of any room.
- Use automated lighting motion sensors and timer controls to reduce lighting up to 45%.
- Use natural light wherever you can and encourage staff and guests to switch off the lights in unoccupied rooms.

Eskom and CTICC energy saving initiative sheds light on energy consumption
Monday, 30 November 2009: A breakthrough technology that interprets real-time energy consumption into financial
and environmental information will help business properties become more sustainable
Eskom has embarked on an energy saving initiative
known as ‘Measure 2 Manage’, which will measure energy consumption in real-time
from 30 November to 7 December, 2009, monitoring the pre-draw and final-draw
activities taking place at the Cape Town International Conference Centre (CTICC).
Eskom is contracting Power Guys to install 36 meters and modems in the CTICC over
the draw period to monitor the centre’s energy consumption in real time.
This data will also be translated into environmental and financial information, made
accessible for viewing via an energy dashboard, and updated every 60 seconds.
A remote automatic meter reading technology will automatically collect consumption,
diagnostic, and status data from energy metering devices and transfer it to a central
database for billing, troubleshooting, and analysing.
The advantages of this technological advance are numerous: it saves utility providers
the expense of periodic trips to each physical location to read a meter, billings can now
be based on near real time consumption rather than on estimates based on previous or
predicted consumption, and this timely information, coupled with analysis, can help both
utility providers and customers better control the use and production of energy
consumption.
“Eskom’s energy supply is still severely constrained and future demand is predicted to
exceed supply unless energy consumers reduce their consumption. With the local
commercial property sector currently consuming up to 16% of Eskom energy output,
commercial properties need to find ways to reduce their consumption not only in the long
term but also in the immediate term,” says Nosipho Maphumulo, General Manager,
Energy Efficient Demand Side Management (EEDSM).

making this information easily accessible to external parties, the remote meter reading
system can also isolate and monitor various rooms or sections of a building making it
even more practical for businesses to find ways to curb energy consumption. At the

for the pre- and final-draw activities, namely:
- The admin, coffee shop and registration areas
- The lights for halls one, two, three and four
- Auditoriums one and two
- The east and west ballrooms
- The Jasmine, Stralitzia and Marimba restaurants

the draw period, as well as energy saving tips and links to further energy saving
information. Visitors to the site will also have the option of registering for periodic energy
saving email alerts.
How the technology works:
|
36 data loggers with an integrated GSM modem were installed at the
CTICC prior to event. Based on Class One metering standards
(within 1%
of accuracy), the unit reads and delivers the following energy
metrics: vaults (v), current (a), active power (kWh), apparent power
(kVA), power factor, reactive power and frequency (hz). |
|
Using GPRS/HSDPA/EDGE or WAP the onboard modem transfers
energy readings every 60 seconds from the CTICC.
|
|
A hexi-decimal file is received on a FTP server every 60 seconds, the
file is processed by a SQL server. This infrastructure is secure, and
independently hosted with regular intra-day back-ups. The process
takes milli-seconds. |
|
Data is packaged for the web and online dashboard and made
accessible via a standard web browser. |
|
Dashboard and website are updated every 60 seconds. Data includes
all energy metrics, environmental information as well as financial and
billing data. |
|
The information is made available online. |
