-With respect to particle emissions, construction is the second main emissions source in the Mineral industries.+Regarding particle emissions, construction is the second-largest emissions source within NFR 2.A - Mineral industries.
  
 ===== Methodology ===== ===== Methodology =====
  
-Since the last update of the UNECE Guidebook, a Tier 1 method is applied to estimate particulate matter emissions. The T1 GB method is used by us with various adaptations to national conditions, so this is already higher tier, perhaps as T1/T2.+Since the last update of the EMEP/EEA air pollutant emission inventory guidebook, a tier1 method is applied to estimate particulate matter emissions.  
 +However, this tier1 method is applied with various adaptations to national conditions improving it to a rather higher tier, perhaps T1/T2.
  
-The approach for uncontrolled fugitive emissions for this source category was adapted for national circumstances within a research Project (Umweltbundesamt, 2016) [(Umweltbundesamt, 2016: Development of Methods for the Generation of Emission Data for Air Pollutants from Building Activity and Construction Zones, Dessau-Roßlau, 2016, https://research.ebsco.com/linkprocessor/plink?id=46c9c9e5-c6f9-3229-b7af-6585eb409115)], partly considered exiting control techniques. As a result, the information of the statistics is combined with modified default emission factors for TSP and PM.+The approach for uncontrolled fugitive emissions from 2.A.5.b was adapted for national circumstances within a research project by Kampffmeyer & Visschedijk (2016) [(KAMPFFMEYER2016)], partly considering existing emission-control technologies. As a result, statistical information is combined with modified default emission factors for TSP and PM.
  
 ==== Activity data ==== ==== Activity data ====
  
-Activity data are determined taking into account figures for various construction activities. Data is based on production statistics (national statistics). According to the method used, figures of area of land affected by construction activities per building were concluded from statistical data and multiplied with emission factors, as explained below. The common uncertainty of 3% for national statistics could be increased as a result of this  calculation, but the effect is not estimated at the moment.+Activity data are determined taking into account figures for various construction activities and based on national production statistics.

 +AD is a result of multiplying the number of houses constructed and a conversion factor.

 ==== Emission factors ==== ==== Emission factors ====
  
-The emission factors used are results of Adaptation of UNECE-Defaults (EEA, 2016) [(EEA2023>EEA, 2023: EEA Report No 03/2023 EMEP EEA air pollutant emission inventory guidebook 2023, Copenhagen, 2023; https://www.eea.europa.eu/publications/emep-eea-guidebook-2023/part-b-sectoral-guidance-chapters/2-industrial-processes-and-product-use/2-a-mineral-products/2-a-5-b-construction/view)].+The emission factors used are results of the adaptation of EMEP/EEA Guidebook defaults (EMEP/EEA, 2023) [(EMEPEEA2023)], for our inventory so-called 'apllied emission factors' with following parameters: 
 +\\ 
 +- pollutant-specific emission factor, not corrected for soil moisture and silt content (kg of emitted pollutants/m² affected area/year), 
 +\\ 
 +- average affected area as product of number of buildings constructed multiplied with conversion factor (average affected area per building), 
 +\\ 
 +- duration of construction activity from default values (EMEP/EEA, 2023)[(EMEPEEA2023)], 
 +\\ 
 +- specification of precipitation-evaporation index and soil silt content as constants, 
 +\\ 
 +- efficiency of emission control measures at the moment see FAQ below.

-The EF is adapted with Moisture Level Correction factor and Silt Content Correction factor in all cases, both 0.20 and 2.22. The assumption about the duration of the construction activity uses the Default values (EEA, 2023)[(EEA2023)]: 
-^ Type of building                                   ^^  Estimated duration (year)      ^^ 
-| Construction of houses (single and two family)     ||  0.5 (6 months)                 ||

-AD is a result of multiplying B the number of houses constructed and f the conversion factor.

 //**Why do German EFs differ from EEA defaults?**// - It has to do with the default 50% reduction for non-residential buildings and roads (as a result of wetting unpaved temporary roads) that is assumed in the calculations for Germany. This is also already accounted for in the EPA emission factors. It is a result of a control measure that is nearly always taken but in principle optional. In the Guidebook a 50% reduction is advised. //**Why do German EFs differ from EEA defaults?**// - It has to do with the default 50% reduction for non-residential buildings and roads (as a result of wetting unpaved temporary roads) that is assumed in the calculations for Germany.
