Kingston Grammar School is an independent coeducational day school in Kingston upon Thames, England. The school was founded by royal charter in 1561 but can trace its roots back to at least the 13th century.
The buildings include the Lovekyn Chapel which is the only remaining free-standing chantry chapel in England and, dating back to 1309, is the oldest complete building in Kingston. Although it is no longer used for religious services, it's the most popular venue in the Royal Borough for civil ceremonies and civil partnerships. As an elegant and bright space with excellent acoustics, it is also frequently used for musical performances and readings

Foreword
Kingston Grammar School approached Go Green Experts in order to establish a baseline carbon footprint and develop an action plan going forward.
The carbon footprint report and action plan will form the basis for strategic environmental planning in the future.
The aim of this review and report is to establish a baseline and identify any gaps in the existing data in order to improve over time.
In order to obtain a more complete picture of the key areas to consider in a reduction plan, any gaps identified have been filled in using estimates based on similar organisations, published figures, and the experience of the carbon consultants using insight based on the site visit.
At the present time, the school does not wish to embark on a Net Zero program, however, this can be reviewed following consideration of the results of this report.
Where primary data was not available, secondary data sources including reports published with Companies House and the Charities Commission were used. An explanation of the data quality and how it is applied can be found later in this report.
An on-site environmental review was conducted by Go Green Experts in September 2022 in order to ascertain the school infrastructure, determine any saving opportunities and define the data required.

1. Executive Summary
Kingston Grammar School is committed to reviewing the environmental impact of the school by measuring our carbon footprint and implementing a decarbonising action plan.
The first step for Kingston Grammar School in creating our decarbonisation plan and strategy has been to measure our carbon footprint. Go Green Experts have begun the carbon footprint measurement process of Kingston Grammar School. During the datagathering process, it was clear that the key area for improvement was the availability of data This is a common issue and can be refined over time.
Carbon emissions including direct and selected indirect emissions, i.e., Scope 1, Scope 2 and selected Scope 3 emissions have been calculated.
The completed carbon footprint, alongside improved data collection and carbon reduction measures implemented as a result of this review, will form a strong foundation for implementing a Net Zero plan in the future if required.
This report was undertaken for the 1st August 2021 to 31st July 2022 period

2. Context
Based on an analysis of the existing carbon footprint, the school can develop a longerterm strategy to improve data collection and reduce emissions.
In the coming years, the school will consider developing a carbon reduction plan in line with the Science-Based Target Initiative (SBTi) guidance, enabling Kingston Grammar School to become a Net Zero organisation over time
To achieve this, Kingston Grammar School will need to set out a number of activities to undertake in its carbon reduction plan, split into short-term, medium-term and longterm activities:
Go Green Experts Ltd have reviewed the following data sets submitted by Kingston Grammar School, which include:
• Energy consumption (Gas and Electricity)
• Water & sewerage.
• Air Travel Data
• Site walk round and review
Estimates have been made for the following items:
• Waste data.
• Significant purchases of goods and services.
• Staff commuting
The data was used to calculate the carbon footprint of Kingston Grammar School including Scope 1, Scope 2, and significant Scope 3 emissions, as referred to in the WBCSD-WRI Greenhouse Gas Protocol emissions in carbon dioxide equivalent.
Scopes 1 and 2 are calculated using the conversion factors listed in the 2020 BEIS Greenhouse Gas Conversion Factors.

3. Carbon Footprint Calculations: Summary
As the first step to setting the carbon reduction strategy, it is critical to set a baseline carbon footprint to enable an understanding of the questions below:
• What are the current carbon emission sources?
• How much carbon is currently emitted?
• Who is responsible for each source’s carbon reduction plan?
Go Green Experts were appointed by Kingston Grammar School to calculate the carbon emissions for each category of consumption
4. Footprint Baseline & Scope
The Greenhouse Gas Protocol defines direct and indirect emissions as follows: Direct GHG emissions are emissions from sources that are owned or controlled by the reporting entity.
Indirect GHG emissions are emissions that are a consequence of the activities of the reporting entity but occur at sources owned or controlled by another entity.
The Greenhouse Gas Protocol further categorises these direct and indirect emissions into three scopes:
• Scope 1: Direct emissions from combustion of gas and other fuels.
• Scope 2: Indirect emissions resulting from the consumption of purchased electricity, heat or steam.
• Scope 3: Other indirect emissions, including those associated with purchased goods and services, leased assets, waste disposal, employee commuting, business travel, and the extraction, production, transport and distribution of purchased materials, fuels and electricity.
Scope 1
Scope 2
Scope 3

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
16
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.

6.8 Reduction action examples- pictures from the site visit
Comments
Pictures from the site visit Draughts: The main front door has several gaps as do some of the sash windows in the staff room
Draught reduction can have a significant impact on reducing energy consumption. Due to the age and construction of the London Rd building, care would be needed to ensure that the insulation products are used. Some companies specialise in old and listed building window door draughtproofing
The Energy Saving Trust state that; ‘Draught-proofing is one of the cheapest and most effective ways to save energy –and Money’.
Lighting was left on in internal and external corridors and rooms during the site visit.
Consider lighting controls or regular checks to ensure lights are not left on for long periods in unoccupied areas. Review lighting throughout the school and replaced it with LED over time.
Boiler room pipe insulation: The pictures above show examples of well-insulated valves and some valves and joints that are not insulated at the sites.
Valve insulation can be cost-effective as well as save emissions of CO2e. The surface area of a 2.5-inch valve is equal to approximately 5 feet of pipe. It was noted during the site visit that the small boiler room in the library had uninsulated valves, the room also had an air conditioning system.
There is a risk that the extra heat from the boiler will be compensated for by the extra energy consumed by the air conditioning system.
A schematic of the heating systems would enable the school to identify areas that can be improved

Example: Thermal images of an uninsulated joint and valve
Rowing club & Gym: Consider electricitygenerating spinning bikes and rowing machines when the current equipment is due for renewal.
Consider replacing old heaters with newer technologies such as infrared heating panels

Appendix A - Calculation Methodology
Carbon Emissions are calculated in accordance with the Greenhouse Gas (GHG) protocol using Carbon Conversion Factors issued annually by the,
• Department for Business, Energy & Industrial Strategy,
• Department for Environment Food & Rural Affairs and
• Office for National Statistics
Emissions consist of several atmospheric greenhouse gases which include Carbon Dioxide (CO2), Sulphur hexafluoride (SF6), Methane (CH4), Nitrous oxide (N2O), Ozone O3, Hydrofluorocarbons (HFCs) and Perfluorocarbons (PFCs). For simplicity of comparison, the global warming potential of all these gases is combined into Carbon Dioxide Equivalent (CO2e). All carbon emissions in this report are in CO2e units.
The formula for calculation is;
GHG emissions (tonnes CO2e) = activity data x emission conversion factor ÷ 1,000
The following is an example that shows a calculation for electricity. There are several causes of emissions from electricity, stated in total kg CO2e per kWh, these are:
These factors vary annually as grid efficiency and the percentage of renewable energy generated nationally change.

Description Scope Factor (kg CO2e / kWh) Emissions attributed to on-site consumption. 2 0.21233 Emissions attributed to transmission & distribution losses. 3 0.01879 Well-to-tank emissions factors for electricity generated. 3 0.05529 Well-to-tank emissions factors for electricity transmitted & distributed. 3 0.00489
Example calculation - Electricity Annual consumption of electricity (kWh) 634,616.8 kWh Emission Source Calculation Total CO2e (Tonnes) On-site consumption 634,616.8 x 0.21233 ÷ 1000 = 134.7 Transmission & distribution losses 634,616.8 x 0.01879 ÷ 1000 = 11.9 Well-to-tank for generation 634,616.8 x 0.05529 ÷ 1000 = 35.1 Well-to-tank transmission & distribution 634,616.8 x 0.00489 ÷ 1000 = 3.1 TOTAL 184.9
Appendix B - Documents and References Used in Calculation.
The calculations were carried out using mathematical models and the methodology defined in the Greenhouse Gas Protocol in particular;
GHG Corporate Accounting and Reporting Standard and Scope 2 Guidance
GHG Scope 2 Guidance
GHG Technical Guidance for Calculating Scope 3 Emissions
The Carbon Conversion Factors are published annually by DEFRA on behalf of the UK government.
