Implementation Process –
For Internal Efficiency Projects
1. Divisions to undertake audits to determine potential energy savings on a
project by project basis (cost recovery for audits to be addressed as part of
the project costs) including potential savings, technologies to be implemented
and projected costs.
2. Prepare project proposal highlighting the business case for the proposed
intervention including comparison with the existing DSM benchmarks
3. Register project proposal with M&V and obtain their input.
4. Measurement & Verification (M&V) must be addressed for all projects (costs
need to be included in project budgets) in order for savings to be counted and
reported.
5. Engage with the relevant energy efficiency experts (DSM, ERID etc.) to
obtain technical approval in writing
5.
Present to relevant divisional committees including investment committees
to confirm the economic viability of the project
6.
Funding to be released after divisional investment committee for approval
7.
Divisions to procure equipment in line with procurement practices and
implement projects
8.
Monthly reporting to the EEC on the status of projects
ESCO –
Complete Audit and prepare a proposal
Important to take Lux measurements
M&V prepare baseline report
Technology Overview
1.
Lighting retrofitting
•
Replacement of old magnetic ballast to new more energy efficient electronic
ballast
2.
Install efficient lamps
•
The downlights was replaced with new generation low voltage lamps (IRC)
provide 30% savings without a reduction in light output. The 50W dichroics
was replaced with 35W low voltage lamps (IRC).
•
Energy saving fluorescent tubes called “Eco tubes”. These tubes were a
direct replacement for the 1.2m (36W) to (32W) and 1.5m (58W) tubes to
(51W)
New Electronic Ballasts
Technology Overview cont..
3.
Install efficient fittings
•
400W Hi-Bay fittings with Mercury Vapour lamps will replaced with energy
efficient “T-Bay fittings”. T-Bay fittings uses the latest T5 lamp technology
and one fitting consists of 4 x 54W T5 linear fluorescent lamps and
electronic control gear.
•
1.8m and 2.4m fittings with T12 tubes are being phased out internationally
due to the low energy efficiency. These fittings will be replaced with single or
double 1.5 meter fittings with electronic control gear.
Hi Bay Lights
Removed Hi Bay Lamps
Scissor Jack and Cherrie picker
used in hard to get places
Technology Overview cont..
4.
Active Lighting Control
•
The installation of occupancy sensors in strategic areas ensured that the
lights were switched off when not used.
5. Active HVAC Control
•
Occupancy sensors will be installed in the circuit feeding an air
conditioner in an office or area in order to switch it off when nobody is
present. Import that each AC had it’s own motion sensor with
contactor
SHE Specification
Planning important – Scaffolding, Cherrie picker crane
Storage of Old Stock – Try to prevent stealing
Counting of removed equipment
Ensure save removal and crushing off site
Scrapping of Magnetic Ballasts
CFL’s and Flourescents
