Introduction

Team Profile Name: Green Inc. “A greener campus is a safer campus” 5 Group members passionate about environmental sustainability.

Project Scope Category: Electricity & Water Consumption Scope 3 (Total indirect GHG) Areas covered include Lower, Middle and Upper campuses for electricity consumption. All campuses local and satellite covered for Water consumption.

Overview There are 3 primary speakers. Discussion items to be presented include: Data collection Carbon footprint calculation Data Analysis Recommendations on Data collection process Recommendations on reduction of emissions Project limitations and challenges Reflection on Group experiences

Data Collection Data Required Contact Person Electricity: Upper campus Middle campus Lower campus Medical School Andre Theys Properties and Services: Engineering Services Manager Water: Main campus Fahzma Jaffar Properties and Services: Finance Manager Building’s Floor Area Sandra Rippon Data Source Co-ordinator Location of installed electricity meters on campus and how they work in accordance to consumption and calculations.

Carbon Footprint Calculation Electricity Grid Emissions factor: “The greenhouse gas Grid Emission Factor (GEF) is the total amount of GHGs emitted per unit of electricity generated for and distributed by an electricity grid, taking in account imports and exports of electricity from the interconnection with other grids.” Electricity-specific Emission Factors for Grid Electricity, August 2011

Carbon Footprint Calculation Electricity Grid Emissions factor: for the financial year ended 31st March 2012 factors of 0.99 and 1.03 t CO2e/MWh were published Factor 1 = 231.9 Mt CO2e emitted ÷ 224.8 TWh sold = 1.03 t CO2e per MWh. Factor 2 = 231.9 Mt CO2e emitted ÷ 233.3 TWh net generated and available for distribution = 0.99 t CO2e per MWh

Carbon Footprint Calculation For the financial year ended 31st March 2012 the calculation is: As denominator, use the TWh number of 250.5 TWh before T&D losses; As numerator, add emissions from: Imports: since this is hydro from Mozambique, the emissions factor is assumed to be 0 t CO2e/MWh; Purchases from IPPs: this is a mix of sources with an estimated emissions factor of 0.85 t CO2e/MWh 17; The total numerator is hence 231.9 + 0.0 + 3.5 = 235.4 Mt CO2e; The revised factor is hence: 235.4 t CO2e emitted ÷ 250.5 TWh = 0.940 t CO2e/MWh.

Carbon Footprint Calculation Water emissions factor: There are two emission factors given by the Defra Conversion Table with one associated with water treatment and the other associated with water supply EMISSION FACTOR DUE TO WATER SUPPLY = 0.3441 kg CO2e per unit EMISSION FACTOR DUE TO WATER TREATMENT = 0.7085 kg CO2e per unit Department for Environment, Food & Rural Affairs [UK], 2012

Data Analysis

Data Analysis Water 181715.3 kg CO2e per unit and 374150.8485 kg CO2e per unit have obtained as GHG emission values associated with water for 2012. These can be used to compare to past and future values, however since carbon emissions related to water consumption have not been calculated in previous reports, these carbon emission values can be used as baseline for future reports.

Data collection Recommendations Water consumption information

Data Collection Recommendations

Data Collection Recommendations Centralized Data Gathering System A complete view of the data which allows multiple queries and abstractions. It is easier to manage a centralized database Offers Real time benefits Easy reporting that benefits management Data integrity can be ensured

Data Collection Recommendations

CHALLENGES AND LIMITATIONS Project related challenges : Unclear requirements from the beginning Changing scope Limited access to valuable Stakeholders

HOW DO WE MOVE FORWARD? Water Consumption: RECOMMENDATIONS Water Consumption: Implement internal monitoring of water consumption Meter large buildings and high capacity residences individually Account for Water usage by Irrigation systems.

HOW DO WE MOVE FORWARD? Electricity Consumption: RECOMMENDATIONS Electricity Consumption: Electricity consumption awareness such as Talks on energy saving, putting “Switch off lights” signs in all buildings Encourage the use of energy saving bulbs, solar power installations and use of paper towels in wash rooms as opposed to powered driers. Power down all computers that are not being used, as opposed to logging off. Offer incentives to the most “green” or environmentally friendly building or residence to encourage energy saving initiatives.

Reflection Project Learning The project combined research into teaching and learning well. It helped to nurture real project management skills. A host of soft skills including Interpersonal relations, punctuality and discipline were at the core of ensuring smooth project running.
