4.4 CO2e Emissions – Breakdown of Business Travel

Commentary

This chart shows a breakdown of travel including air and local coach travel.

The GHG conversion factor used was kg CO2e per mile travelled plus “Well to Tank” factor for each type of travel.

Well-to-tank (WTT) conversion factors for transport relate to the upstream Scope 3 emissions associated with extraction, refining and transportation of the raw fuels before they are used to power the transport mode. These are included in accordance with GHG protocol principles.

Coach travel has been estimated, further investigation should be completed to gain a more accurate figure.

4.5 CO2e Emissions – Breakdown of Purchases

Kingston Grammar School Purchases Emissions

Commentary

The supply chain data used was based on the amount spent in the period on the categories listed in the latest accounts published on Companies House. The emissions were calculated using generic sector specific carbon intensity (CO2e pound £ pound) figures provided by the UK Office for National Statistics.

4.6 CO2e Emissions – Scopes 1, 2 & 3

Emission Scopes are defined by the internationally accepted Greenhouse Gas Protocol. The protocol has been developed through many years of cooperation with The World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD).

They are based on an assessment of which emissions from operations the organisation can directly control versus those which the organisation can merely influence.

The below diagram summarises the categories of emissions that are classified into each scope.

5. Decarbonising the Energy in the School.

Due to the construction of the buildings and the layout of the site, the opportunities for improving efficiency are significant. However, there are many complications and implementing a strategy to reduce emissions will take time and resources.

Developing a ten-year plan would help to spread the load on both manpower and resources.

Reducing gas consumption through efficiency measures should be considered. Ensuring that energy efficiency is maximised should be prioritised.

Behaviour change can contribute to a significant reduction in energy consumption

Moving away from natural gas: Possible change over from natural gas to other technology in the future.

Solar Thermal for Water Heating: Solar hot water could be used to supplement gas or electricity for the hot water needs of the main school and the sports facilities.

Introduction of renewable electricity using solar panels with possible battery storage: Assess the viability of on-site renewables, such as solar panel (PV) systems.

Obtain quotes and estimated generation capacity of solar systems at the school.

Solar Photovoltaic systems can be installed on the roof of the buildings subject to engineering and planning constraints.

If a 30kW system could be installed on the South facing roof of the Michael Fryan Theatre the estimated energy generated could be in the region of 30,500 kWh giving a reduction of approximately 10 tonnes of CO2e per annum

A full feasibility study would be required, the graph below shows the possible monthly output, a large percentage of the energy generated will be when the school is not operating at full capacity. Other factors to consider would be grid connection and energy consumption patterns of the buildings

Quotes should be obtained from reputable suppliers, the current energy supplier

TotalEnergies Gas & Power offer a solar solution that could be investigated in the first instance.

Utility suppliers:

TotalEnergies Gas & Power currently supply the energy to the school have committed to achieving Net Zero by 2050. The school should engage with TotalEnergies to investigate the ‘Green Gas’ option currently offered to reduce emissions in the short term. (see action plan section 3).

Examples of low-cost actions:

Drawing curtains on large windows; our thermal imaging report on a double-glazed patio door shows a 1.6°C difference in the heat transferred from the closed side and the open side.

Draughtproofing; the building has many places where draughts can be found. As up to 30% of heat can be lost in this way, it may be worth investigating measures to reduce the larger areas where draughts can enter

Reflective radiator panels. These fit on outside walls behind radiators and reflect heat into the room, therefore reducing the heat transfer from the building. Reflective panels are calculated to have an energy saving potential of 170kWh per square meter. As these are not aesthetically pleasing it is unlikely that they will be appropriate for every room.
