1 Energy Home Energy Reduction A CCF project is offering energy efficiency advice to householders. Each householder is asked what their yearly gas and electricity consumption is during the energy advisor s first visit. The energy advisor then makes recommendations on how to reduce their energy consumption. During the follow up visit each householder provides the energy advisor with their new gas and electricity consumption figures. Prior to the home energy visits one householder consumed 2500 of electricity and 6750 of gas between the 6 months October - March. After receiving home energy advice they reduced their electricity and gas consumption to 2100 and 6050 respectively over the same period the following year. What is the 1 year and lifetime CO₂e savings of the energy efficiency advice? ENERGY Fuel Used Amount Unit Factor Electricity from Grid Natural Gas from Mains Heating Oil (kerosine/parrafin) litres Coal (domestic) kgs Wood logs kgs Wood chips kgs Wood pellets kgs You will notice that the figures provided are in, which match the Unit or indicator required for the CO₂e calculation. The figures are for 6 monthly energy usage, therefore we need to manipulate the data prior to using the CO₂e calculations template overleaf. The emissions factors for grid electricity and natural gas are different, therefore two separate calculations need to be done. TOTAL

4 Energy Fuel Type A CCF project is offering home fuel advice to householders. Each householder is asked what their yearly gas consumption is during the energy advisor s first visit. The energy advisor then provides information on alternative, cleaner fuels. During the follow up visit each householder provides the energy advisor with their new energy consumption figures. Prior to the home energy visits one householder consumed of gas per year. After receiving fuel advice they changed their heating source from natural gas to wood chips. The householder uses 5T of wood chips annually to heat the home. What is the 1 year and lifetime CO₂e savings of the energy efficiency advice? ENERGY Fuel Used Amount Unit Factor Electricity from Grid Natural Gas from Mains Heating Oil (kerosine/parrafin) litres Coal (domestic) kgs Wood logs kgs Wood chips kgs Wood pellets kgs You will notice that the figures provided are in and tonnes. The natural gas unit matches the given unit in the table, however the wood chip weight must be converted from tonnes to kgs. Wood chip 5 x 1000 = 5000kg The indicators are now in their correct format to use in the CO₂e calculation template overleaf. TOTAL

6 Energy Community Building Eco-refurbishment A CCF project is refurbishing their community-owned building to include energy efficient measures and lower electricity and gas usage. The last annual energy bill prior to the eco-refurbishment stated that annual electricity usage was 18000, and annual gas usage was Post-installation the energy bill received stated that annual electricity and gas usage had decreased to and respectively. What is the 1 year and lifetime CO₂e savings of the eco-refurbishment?

The figures are also for annual energy usage, therefore we do not need to manipulate the data prior to using the CO₂e calculations template overleaf. However, the emissions factors for grid electricity and natural gas are different, therefore two separate calculations need to be done. TOTAL
