GSHP design: Guidelines and Standards Dr. Burkhard Sanner European Geothermal Energy Council, Brussels www.egec.org

Standards and guidelines • European Standards (EN) - EN are generally normative • International Standards (ISO) - ISO are not normative although should represent best practice and should be followed • National Specifications (e.g. DIN, VDI, etc.) - Standing varies between countries, should be observed for best practice technical purposes

European Geothermal Energy Council www.egec.org

European Standards Implementation status • Heat Pumps - there are comprehensive and harmonised technical standards for the equipment - EU member states (+ CH, NO, IS) have adopted the EN standards for testing, rating and safety of heat pumps

European Geothermal Energy Council www.egec.org

European Standards Existing standards on heat pumps in general • EN 378-1:2000 Refrigerating systems and heat pumps – Safety and environmental requirements – Part 1: Basic requirements, definitions, classification and selection criteria • EN 14511-1:2004 Air conditioners, liquid chilling packages and heat pumps with electrically driven compressors for space heating and cooling – Parts 1-4 • ISO 13256:1998 Water-source heat pumps -- Testing and rating for performance Part 1: Water-to-air and brine-to-air heat pumps Part 2: Water-to-water and brine-to-water heat pumps European Geothermal Energy Council www.egec.org

European Standards Implementation status • Shallow Geothermal Systems - no standards on EU-level (EN) (CEN TC 341 is working on standard for TRT) - technical standards exist in the countries where the market already has developed. This includes DE, SE, AT and CH - certification of installers and drillers exists also only in countries with developed market

Standards and guidelines for GSHP In the GSHP sector, standards may cover: • General definitions • Design Standards for capacity, efficiency, safety • Installation Standards concerning environmental protection, drilling, • Standards related to competence and certification of installers and drillers • Standards related to system testing • Regulations and guidelines for licensing/ permitting of systems (typically concerning groundwater protection)

European Geothermal Energy Council www.egec.org

Standards and guidelines for GSHP European Standards somewhat relevant to GSHP systems • EN 12828:2003 Heating systems in buildings – Design for water-based heating systems • EN 12831:2003 Heating systems in buildings - Method for calculation of the design heat load • EN 15316/4/2:2008 Heating systems in buildings - Method for calculation of system energy requirements and system efficiencies - Part 4-2: Space heating generation systems, heat pump systems • EN 15450:2007 Heating systems in buildings.

European Geothermal Energy Council www.egec.org

Standards and guidelines for GSHP EN 15450 : 2007 DESIGN OF HEAT PUMP HEATING SYSTEMS • This is the first general EN standard for heat pump systems and concerns the design of heat pump systems for water/ground-source and air-source. • This standard contains the following: - System requirements - Installation requirements - Commissioning of the system - Maintenance requirements

European Geothermal Energy Council www.egec.org

Standards and guidelines for GSHP EN 15450 : 2007 DESIGN OF HEAT PUMP HEATING SYSTEMS • EN 15450 elucidates the basic problem for a geothermal standard on a European level: - Climatic conditions throughout Europe vary widely giving large differences in heating/cooling demand - Geological conditions vary widely from unconsolidated soils to hard, crystalline rock - Traditions in heating and cooling vary • As a result, EN 15450 can only give a general minimum framework for design and installation, with many items to be filled in locally or regionally

European Geothermal Energy Council www.egec.org

Standards and guidelines for GSHP EN ISO 22475 : 2006 GEOTECHNICAL INVESTIGATION AND TESTING • Sampling methods and groundwater measurements Part 1: Technical principles for execution Part 2: Qualification criteria for enterprises and personnel Part 3: Conformity assessment of enterprises and personnel by third party • Covers sampling, measuring, testing, qualifications Part 1 is normative Parts 2 and 3 are Technical Specifications (TS)

European Geothermal Energy Council www.egec.org

European Standards - Conclusion What is needed: • The introduction of EN and ISO standards for heat pumps has been crucial as these products are manufactured and traded throughout Europe. The current market would not exist without EU-wide standards. • Drilling and installation for shallow geothermal systems is a service rendered by local contractors so the need for harmonised standards is not so urgent • In many countries no guidelines and standards exist and thus consumer protection is not guaranteed. Here a negative impact on the market can be expected if demand increases and poor workmanship is delivered in countries without specific standards • Further Standards at European level seem to be necessary European Geothermal Energy Council www.egec.org
