Umbono Engineering (Pty) Ltd is a member of the Green Building Council of South Africa and is actively involved in a range of energy e ciency opportunities which seek to both provide solutions for the public and the private sector.

With our core focus being Electrical Engineering consulting services, mainly in the HV (Transmission and Distribution Lines and Substations), MV (reticulation designs for both power and water infrastructure), LV (Building works – O ce Buildings, Commercial Buildings and mass residential Developments) and Finally Renewable Energy (Renewable Generation Plant integration into the network), energy e ciency is always the undertone of our designs.

Mainly in the LV design services, Municipalities are starting to realize the value that energy e ciency can add to their bottom line and hence part of our services to municipalities involves technical audits of their outdoor infrastructure (Street lights and high mast lights, waste water treatment works) and indoor infrastructure (building lighting and air-conditioning solutions) and advising them on what alternative technologies are available in the market to improve their electricity consumption.

1. Pre-Audit data Collection – This step is mainly about understanding the client’s concerns, why are they looking at an energy e ciency project, what infrastructure are they concerned with and age and any background technical and nancial information on the infrastructure.

2. Technical Audit – deployment of engineers onto the client’s site to conduct technical audits and capturing of technical data regarding the technology to be investigated.

3. Data analysis – this stage involves detailed technical analysis and nancial analysis of the costs associated with operating and maintaining the technology being investigated.

4. Technology scan and comparison – this stage involves scanning of industry’s latest and best practices regarding the technology in question from both a technical and ops and maintenance cost perspective vs the current costs of operating and maintaining the existing technology.

5. Recommendation – the most optimal solution, tting both the client’s budget, time and production targets will be recommended based on the outcome of stage 5.

6. Procurement and implementation – this process involves identi cation of relevant technology partners for the supply of the technology to be utilized and also appropriate installers of whatever technology is being implemented.

7. Measurement and veri cation – this is the last stage of continuously measuring the actual performance of the implemented solution versus the proposed and expected improvements and veri cation on whether what was promised as an improvement is being achieved and if not what are the improvement areas that need to be addressed
