The outdoor temperature data collected by the thermometers and data loggers situated outside the house has been transformed intoHeatingDegreeDay (HDD) andsummedfor eachweekofmeasurement.TheHDDisameasurementdesigned to reflect the demand for energy needed to heat a building. It is calculated by counting themissingdegrees to reachacomfort temperature.Thecomfort temper- ature has been determined at 18 C and the HDD18 (explain abbreviation) is calculated as follow: Equation10.2:Calculationof theWeeklyHeatingDegreeDayValue WeeklyHDD18¼ X d¼day18 DailyTemperatured Similarly the indoor temperature data collected by the thermometers and data loggers are used to calculate theweekly average indoor temperature. Based on these data first analysis of the differences in energy consumption and HDD18are available betweenPSHandnon-PSH. 10.2.4 GreenhouseGasCalculation TheGHGemissionswere calculated from the energy consumptionusing theGold StandardGHG calculationmethodology “Technologies and practices to displace decentralized thermal energy consumption7” and IPCC emission factors.8 For biomass fuels, the calculation of the fraction of non-renewable biomass (fNRB) wasbasedon theGoldStandard-approvedmethodologyusingFAOdata. TheoverallGHGreductionsachievedby theproject activityare thencalculated as follows: ER¼ X BE X PE X LE Where: ER¼Emission reduction (tCO2e/year) BE¼Baseline emissions for the nonPSH(tCO2e/year) 7Available on http://www.goldstandard.org/wp-content/uploads/2011/10/GS_110411_TPDDTEC_ Methodology.pdf 8IPCC, “Energy,” in 2006 IPCCGuidelines forNationalGreenhouseGas Inventories, vol. 2, 5 vols.
