The Department formed Energy Efficiency task team (EETT) on 14th February 2008.

Purpose was to ensure a co-ordinated energy programme in State-owned buildings.

Formulated Energy Code of Conduct for all buildings under the custodianship of National Department of Public Works (NDPW) for implementation by National Government Departments using state owned and leased buildings for occupants to contribute to conservation of energy.

Specifications Adjusted to Energy Savings Measures

Building Fabric

Building Design for Orientation to gain Solar Energy heat in winter and shade solar heat in summer months

Installation of suitable glazing for solar interactions with building facades

Installation of appropriate shading devices essential

Installation of appropriate insulations in strategic locations

Insulate hot water pipes to save energy

Harvesting sun and wind energy by solar geyser, natural cross ventilation for rooms ventilation

From 1997 Ndpw implemented shared energy contracts in 4 Regions with shared ratio (Pretoria 50:50, Cape Town 60:40, Johannesburg 60:40,Bloemfontein 60:40).

The energy audit and retrofit for Pretoria started in 2003 to 2010 on approximately 104 sites and derived savings of 1,147,608kw/h and R 311,973,659. over this period. The contract was extended to 2020 and the savings achieved to date is 101,770,824kw/h and R36,203,787.00

Johannesburg Regional Office started energy audits from 2000 to 2010 on 24 sites comprising of 600 buildings with the subsequent energy savings of R 46,629,107.00

and 108,641,210.00kw/h. The Contract expired on 15th December 2011.

The project also constituted lighting retrofits of 48,856 luminaries at a cost of R33,6 million including the replacement of electricity with excess steam in Zonderwater Prison and optimisation of HVAC at Union Building.

Progress (Cont.)

In 2011 - Shared Energy Contractor appointed in the following Regions : Cape Town, Durban, Polokwane and Mmabatho. The energy savings have not been realised in Durban, Polokwane and Mmabatho to date except Cape Town whereby energy saving to date is report in page 4 above. ( In Implementation)

Behavioural Changes Implemented

•Inter Departmental Task team on Energy decided in August 2010 that Behavioural Change on saving energy in Public Buildings was required.

•The SAVE IT Energy Efficiency Campaign was implemented by GCIS in collaboration with DPW from 19th January 2011 to 17th March 2011.

•Campaign targeted to save 10% on energy consumption on all Public Buildings

•All Dpw Regional Offices, and User Departments were educated accordingly – series of workshops held.

Projects Implemented Through IDT

• Budget of R75m and R70m for 2010/11 and 2011/12 respectively.

• 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.

Projects Implemented Through IDT (Cont.)

• 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.

Scope of Work on Projects Implemented Through IDT

• 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.

Challenges Encountered How Challenges were resolved

No existing As-Built plans

available

Contractors documented changes as an annexure to the

Certificates of Compliance

Access to facilities The Department of Public Works issued the security clearance

letters to allow the Contractors and Consultants access

User clients, SANDF and DCS

had stringent security and they

limit the number of personnel

working in their building

The Contractors resources had to be reduced and re-allocated to

other sites, in order to shorten the installation period at those sites.

DPW planned projects Recommendations were made not to proceed with implementation

of the Energy Efficiency Programme at the identified sites.

Procuring materials within a short

timelines

Contractors were advised to source materials from reliable local

companies

DPW long term maintenance

contracts

Meeting was held with representatives from Regional DPW,

maintenance contractors and EEP service providers and indicated

to them that certificate of compliance for light fittings will be

provided to them.

Challenges on Projects Implemented through IDT

• 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 than the savings and reduced carbon footprint created at the museum, was the excellent exposure of the benefits of energy efficiency interventions to both the young and old visiting the facility.

Impact at Luthuli Museum

• The impact areas that were completed, led 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

Conclusion on Implemented Projects

• Some of the challenges encountered include the following:- Dedicated professional services unit with qualified electrical engineers

aligned to size of portfolio- Intensifying Monitoring and Evaluation - Partnership with DOE need to be

instutionalised – MOU.- Engagement with Eskom Demand Management – needs to derive more

benefit for state – 10 buildings identified for pilot project.

• 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.
