FNB FAIRLAND PROJECT: MIGRATING FROM A GBCSA 4 STAR RATING FOR EXISTING BUILDING TO A 5 STAR

Summary:
Fairland was the biggest office rated on the first ever existing building GBCSA pilot programme held in South Africa. With LTM Energy’s assistance and multiple energy efficiency projects successfully implemented over the last 4 years, they achieved a 4-star rating in 2016.

Recently, amongst other energy projects, LTM Energy has successfully installed a 1992kWp car port PV at Fairlands to migrate the Campus from its current 4-star rating to a 5-star. This is one of the biggest solar carports in Africa.

The Fairland office development is unique in the South African office development landscape and is set to be held up as a new standard for unique, functional, environmentally responsible and aesthetically pleasing buildings.

LTM Energy’s success story of total metered energy reduction of the Campus of 6 201 484 kWh/p.a (more than 30% of the campus’ consumption) can be replicated across many corporate clients around the country which would ensure a huge positive impact to South Africa’s carbon footprint reductions let alone the ramifications globally.

More Details:

Following the successful appointment and implementation of a
Grid-tied rooftop PV Facility at FNB Selby, LTM Energy (Pty) Ltd
was appointed in 2014 by FNB to investigate and turn their
Fairland Campus into “one of the lowest Power Consumption
and Carbon Footprint buildings in Africa” (FNB management vision).

 

 

 

 

FNB Fairlan Breakdown of Electricity usage 

Taken into account the specific energy consumption profile of the building and following a detail audit, LTM Energy embarked on 14 different energy projects to increase efficiency and harness green energy, hence lowering the building’s carbon footprint. These initiatives reduced the campus’ energy consumption by more than 30% and the maximum demand by more than 40%. Initiatives included:

  • Reduction in Air-conditioning consumption (chiller soft start, new time schedules for air handling units, FCU, FPU, pumps and motors)
  • Reduction in Lighting consumption (multiple lighting project including florescent lights, LED retrofit, sensors and schedules)
  • Supply voltage optimization
  • Reduced Escalator consumption (reduced operating hours)
  • Power factor correction
  • More efficient water heating (installation of heat pump, isolation and reduced hot water usage.

The combined pay-back period of these initiatives were less than 6 months, as illustrated in the table below. Measured against SANS recommendations and similar building in its category, the building now performed above par. In fact, it was in line with best practice, especially if looking at an existing building project.

During 2015, LTM Energy as the appointed accredited sustainability professionals, assisted FNB in obtaining a 4-star Green Star rating for the Fairland Campus as the single biggest office in Africa to be rated at this level. This was widely celebrated as an excellent achievement for an existing building.

FNB Failands

Building on the successes of FNB’s relationship / association with LTM Energy, FNB management decided to lift the bar higher: FNB challenged LTM Energy to identifying further efficiency and/or carbon reduction initiatives and present management with business cases and implementation plans.

As a result, LTM Energy has recently replaced the old carport systems at Fairland with a 1992kWp grid-tied solar PV carport as seen in the video clip, which is estimated to reduce the grid dependency of the campus by 3 million kWh/p.a, worth a saving of about R3.4m p.a. to FNB. A further 240kWp PV carport is soon to be added, as a secondary project as well as an agreement with City Power to inject power into the grid during certain peak hours.

In addition to the solar PV carport system, LTM Energy identified several other innovative projects that would make FNB the leader in their category of commercial buildings. These include rain water harvesting and grey water recovery, further energy efficiency projects including latest LED and perimeter lighting technologies, a hybrid PV / standby generator solution to reduce diesel usage during standby operations, charge points for electric vehicles, waste to energy projects, educational programs, demand response, smart switches, tariff optimization and more.

Over a period of about 3 years, LTM energy will be assisting FNB in turning their Fairland campus from a “soar eye” in terms of energy consumption, to a flagship within Africa, fitting with international best practice. Besides the fact that these projects pay for itself within a few months in most cases, FNB is specifically impressed with the marketing and sustainability benefits the initiatives brought. The bonus was when Management got feedback on the enormous impact the energy efficiency drive at work (which includes awareness and training) had on their employees and their private lives / houses.

With the initiatives currently under way and newly identified projects, FNB management is looking forward to a “5” star Green Building rating in 2017, making the Fairland Campus an industry leader in respect of not only aesthetical design, but also energy and water efficiency. The First Rand group, inspired by FNB and Wesbank, however don’t settle for “good”: They want to be the undeniable best, and therefore challenged LTM Energy once more to take the building to an unheard off 6-star for existing buildings, in years to come. Our reaction of cause: “GAME ON !!”

It is clear that LTM Energy is a leading Energy Efficiency Company, supported by their “out of the box” and “bigger picture” thinking. LTM Energy proofed that they can, over a fairly short period of time, apply their innovation and ability to integrate various disciplines of energy and water efficiency with renewable and traditional energy generation, waste recovery and a culture of efficiency and re-use, to bring about huge savings to their clients and the environment. All of this are cleverly underpinned by Senior Management buy-in and workable policies, guidelines and educational programs, to ensure sustainability and ongoing improvement.

LTM Energy’s leadership and vision in the field of energy and water efficiency, harvesting renewable resources and reclaiming waste, goes beyond known boundaries. As a company we dream about replicating these success stories to hundreds of customers in a similar situation all across Africa. The carbon impact of the reduction in energy usage, impact of the water harvesting and reclaiming programs and monetary value of the associated cost savings of such a roll-out could be one of the biggest green initiatives that Africa has ever seen!
