  20. 20. Dutch Approach Facts & Figures • STEK: public private partnership (foundation) with 18 years of experience • Certification of personnel: 24.000 diploma’s • Certification of installers: 2000 stationary • Auditing through independant bodies every 18/24 months (audit of installer and installations by end- user) • Assessment by STEK assessors • No Training/Education: is for the free market Thematic Meeting Hungary 19-10-11 20
  21. 21. Dutch Approach Facts & Figures  High awareness about the environmental impact of RAC & heat pump equipment by the industry sector, including certified installers, their personnel and operators  Equipment quality improved. Equipment manufacturers and installers increased the quality of both equipment (longer life cycle) and services  Operators/and-users benefit from a higher reliability of their systems and thus higher productivity of their own activities  Lower operational costs for operators due to professional leak checks resulting in direct refrigerant and spare part savings. Leak-tight equipment, ensuring optimal refrigerant charge, also results in higher energy performance.  Higher quality education and training through assessment structure  Real leakage rate figures based on the refrigerant registration by certified installers. Emission figures 3-5 % depending on refrigerant/application Thematic Meeting Hungary 19-10-11 21
  22. 22. Dutch Approach Facts & Figures • 8000 Active STEK-technician/year • STEK fee for installers = € 500 per STEK-Technician/year • Average yearly STEK installers fee: by 3 STEK technicians € 750 • Overhead costs: € 125 per STEK technician • Productivity: 1500 hours per STEK Technician/year Result STEK system costs per STEK Technician/hour: € 0,33 (€ 500/1500hr) Thematic Meeting Hungary 19-10-11 22
  23. 23. Dutch Approach SPARK Project EU Leonardo da Vinci project 2010 - 2012 Partners: B, UK, D, H, and NL To develop a test for new RAC personnel For the Job profile’s  Craftsman Category I  Craftsman Category II  Installation technician under supervision Category I  Recovory Technician Category III  Tecnician only leaking/tightness check Category IV  Heat pump installer circuit content below 3 kgr without breaking in the circuit Thematic Meeting Hungary 19-10-11 23
