  1. ENERGY EFFICIENCY INTERVENTIONS IN GOVERNMENT DEPARTMENTSBRIEFING TO THE PORTFOLIO COMMITTEEPrepared by: The Independent Development Trust 23 October 2012

  2. Purpose To present to the Portfolio Committee on Energy Efficiency Interventions in Government Departments undertaken by the Independent Development Trust

  3. EE PROGRAMME BACKGROUND • “In South Africa, Government is taking the lead by using Public Buildings as an example. Cabinet has approved the implementation of a programme of energy efficient measures in National Government Buildings which is currently underway and which will be extended to provincial and local government.” Extract from Foreword of RSA Energy Efficiency Strategy: March 2005 •  The above extract echoes the need addressed by current energy efficiency initiatives. The impact made by such programmes, result in the reduction of energy consumption and a reduction in the carbon footprint of facilities. Direct costs savings from such initiatives will reduce Government spending.

  4. EE PROJECTS BACKGROUND • The National Department of Public Works (NDPW) appointed the Independent Development Trust (IDT) to implement the Energy Efficiency Programme (EEP). The programme was aimed at reducing the electricity consumption at selected NDPW facilities through a targeted energy efficiency intervention. The National Department of Public works identified 120 facilities [Eastern Cape (60), Mpumalanga (30) and Northern Cape (30)] for this particular implementation. The programme was undertaken over two financial years i.e. FY 2010/2011 and FY 2011/2012. • The Independent Development Trust was also appointed by the National Department of Public Works (NDPW) as an implementing agent for the implementation of the Green Building Programme on selected State Owned Buildings in the Kwa-Zulu Natal Province for the COP17. The Luthuli Museum building was selected to be showcased during the period of the COP17 International Conference proceedings of the countries Green Building Programme. The programme was undertaken over one financial year i.e. FY 2011/2012.

  5. SCOPE OF WORKS • The energy efficiency intervention at the 120 facilities situated in the three (3) provinces, focused primarily on lighting and remote metering at various state-owned facilities. • The scope of work at the Luthuli Museum included various interventions ranging from water conservation, electrical and mechanical energy savings and other greening initiatives.

  6. IMPACT UNDER THE EEP IN EC, MP & NC (1) • Table 1: Summary of Audited / Completed projects • Note: The total value of the projects are R127m for the FY 2010/2011 and FY 2011/2012 combined

  7. IMPACT UNDER THE EEP IN EC, MP & NC (2) • Table 2: Annual Energy Savings per province Assumptions: 1. The hours of operation of each facility are different, for this programme the operational hours was kept at 12 hours per day, and 365 days was used to determine the Annual energy savings. 2. The rate/ tariff of 40c per kWh was used to calculate Annual Energy savings’ cost

  10. IMPACT AT THE LUTHULI MUSEUM (1) • The impact areas identified and installations that were completed accordingly were: • Rewiring of the Electricity Distribution System, HVAC enhancements, Lighting enhancements , Solar PV and Switching Controls • Water Efficiency Devices and Water Heating • Passive Energy Controls • Automated Remote Metering Systems • The most important element other then the savings and reduced carbon footprint created at the museum, was the excellent exposure to both younger and old visiting the facility of the benefits of Energy Efficiency Interventions.

  11. IMPACT AT THE LUTHULI MUSEUM (2) • The impact areas that were completed, lead to the following savings accordingly: • The existing HVAC equipment was replaced with a 40% more energy efficient system • Existing fluorescent light bulbs were replaced with LED bulbs which are powered via the Solar Technology installed • The installation of computerized irrigation and water harvesting systems led to a reduction of approximately 30% in water savings • Automated Remote Metering Systems for the electricity and water usage were installed to monitor readings every 30 minutes (leak detection was also included) • The total value of the project was R6m for the FY 2011/2012

  12. IMPACT AT THE LUTHULI MUSEUM (3)

  13. CONCLUSION ON IMPLEMENTED PROJECTS • The energy efficiency initiatives were implemented successfully due to the remarkable commitment of all stakeholders. This complemented the development and implementation of the most efficient and cost effective energy saving methodologies. The IDT has completed all programmes over the two financial years i.e. FY 2010/2011 and FY 2011/2012 and currently is not working on any further initiatives in this regard.
