Green Practices Guideline for Services Sector

3.3. COMPUTATION The energy and fuel saving for the reporting period can be calculated using the following equations: Percentage (%) of energy saving = Total energy consumed  Total energy consumed for the year of reporting - for the baseline year (unit for energy)  (unit for energy) Total energy consumed for the baseline year     x 100% (1) (unit for energy) Percentage (%) of fuel saving = Total energy consumed  Total energy consumed for the year of reporting - for the baseline year (unit for fuel)   (unit for fuel) Total energy consumed for the baseline year     x 100% (2)  (unit for fuel) NB: Negative (%) indicates there is savings, positive (%) indicates there is no savings 3.4. ASSUMPTIONS AND UNCERTAINTIES Wherever fuel characteristic information is used for calculations, it shall be noted that the averaging of such characteristics (i.e., calorific value) contributes to uncertainties. Any and all averaging approach to consumption data shall be noted and wherever practicably possible the uncertainties shall be quantified. Total energy consumed for the reporting period shall be calculated based on the actual consumption of energy for each month within the reporting period. In the event of data unavailability, average consumptions can be provided. Averaging approaches and assumptions made should be described in sufficient detail. Total fuel consumed for the year of reporting shall be calculated based on the actual consumption of fuel for each month within the reporting period. Each type of fuel should be calculated separately. Suggested unit for fuel as follows: • Liquid fuel (i.e., petrol, diesel, oil, etc.): litres of fuel • Solid fuel (i.e., coal, woodchip, etc): kg of fuel • Gaseous fuel (i.e., natural gas, LPG, etc.): MMBTU or cu. ft. of gases If the organisation is reporting both energy and fuels, the energy units should be standardised in MWh or MJ and reported in combination. 4. OTHER METHODOLOGICAL CONSIDERATIONS 4.1. COMMENT AND LIMITATION There are no limitations to this indicator. 4.2. VALIDATION Measurement and Verification (M&V) report to verify savings endorsed by certified M & V professional. 4.3. QUALITY MANAGEMENT Not applicable. 5. REFERENCES AND DOCUMENTATION 1. National Energy Policy (2022–2040). 2. National Energy Efficiency Action Plan 2016–2025. 3. The Sustainable Development Goals (SDGs). 98 GREEN PRACTICES GUIDELINE FOR SERVICES SECTOR
