• Data collection

• Current system is tedious and ineffective and not managed effectively.

• Delays are caused because the collection of data is not collected in a standardised format

• Often the data is incorrect and/or incomplete

• Powerstar has proven to be problematic.

Situation of Concern

• Reduce UCT’s expenditure on electricity

• Through better data recording, there is an opportunity for improved managerial decisions to be made going forward.

• By lowering electricity usage the university is reducing the core contributor to its carbon footprint.

Business Opportunities

• Await results regarding refitted environmentally friendly equipment as well as add further environmentally additions to the campus

• Use the IS department and the class of INF3011F to address the problem at hand.

• Hire external, private sector help.

Analysis of Options/Alternative Solutions

• Improve the current data collection method

• Calculate UCT’s carbon footprint caused by the scope 2 indirect upstream activity

• Report fact-based conclusions on findings which are comprehensible and contextual regarding our project.

Recommendations

Sustainable Data Collection Recommendations

• Implement an improved automated system that records energy consumption more efficiently and accurately.

• Standardize data capture templates across all campuses.

• Apply built-in conditional formatting and interactive graphs to Excel templates to highlight input errors.

Data Capture Template

Per Campus Data Capture Template

Infographic

• Incorrect data

• Delay in receiving accurate data

• Time slot which suits everyone

• Load shedding

• New power star data holder/controller

• Error on billing data

 Challenges

• 3 month time frame

• Power-Star Anomalies

• Two source of data

• Building meters

Limitations

• Main group issue was communication.

• Used effective techniques which include:– Serious Creativity– Prpic’s model of reflective practice
