The UK is committed to a target of reducing greenhouse gas emissions by 80% before 2050. With over 40% of fossil fuels used for low temperature heating and 16% of electricity used for cooling these are key areas that must be addressed. The vision of our interdisciplinary centre is to develop a portfolio of technologies that will deliver heat and cold cost-effectively and with such high efficiency as to enable the target to be met, and to create well planned and robust Business, Infrastructure and Technology Roadmaps to implementation. Features of our approach to meeting the challenge are: a) Integration of economic, behavioural, policy and capability/skills factors together with the science/technology research to produce solutions that are technically excellent, compatible with and appealing to business, end-users, manufacturers and installers. b) Managing our research efforts in Delivery Temperature Work Packages (DTWPs) (freezing/cooling, space heating, process heat) so that exemplar study solutions will be applicable in more than one sector (e.g. Commercial/Residential, Commercial/Industrial). c) The sub-tasks (projects) of the DTWPs will be assigned to distinct phases: 1st Wave technologies or products will become operational in a 5-10 year timescale, 2nd Wave ideas and concepts for application in the longer term and an important part of the 2050 energy landscape. 1st Wave projects will lead to a demonstration or field trial with an end user and 2nd Wave projects will lead to a proof-of-concept (PoC) assessment. d) Being market and emission-target driven, research will focus on needs and high volume markets that offer large emission reduction potential to maximise impact. Phase 1 (near term) activities must promise high impact in terms of CO2 emissions reduction and technologies that have short turnaround times/high rates of churn will be prioritised. e) A major dissemination network that engages with core industry stakeholders, end users, contractors and SMEs in regular workshops and also works towards a Skills Capability Development Programme to identify the new skills needed by the installers and operators of the future. The SIRACH (Sustainable Innovation in Refrigeration Air Conditioning and Heating) Network will operate at national and international levels to maximise impact and findings will be included in teaching material aimed at the development of tomorrows engineering professionals. f) To allow the balance and timing of projects to evolve as results are delivered/analysed and to maximise overall value for money and impact of the centre only 50% of requested resources are earmarked in advance. g) Each DTWP will generally involve the complete multidisciplinary team in screening different solutions, then pursuing one or two chosen options to realisation and test. Our consortium brings together four partners: Warwick, Loughborough, Ulster and London South Bank Universities with proven track records in electric and gas heat pumps, refrigeration technology, heat storage as well as policy / regulation, end-user behaviour and business modelling. Industrial, commercial, NGO and regulatory resources and advice will come from major stakeholders such as DECC, Energy Technologies Institute, National Grid, British Gas, Asda, Co-operative Group, Hewlett Packard, Institute of Refrigeration, Northern Ireland Housing Executive. An Advisory Board with representatives from Industry, Government, Commerce, and Energy Providers as well as international representation from centres of excellence in Germany, Italy and Australia will provide guidance. Collaboration (staff/student exchange, sharing of results etc.) with government-funded thermal energy centres in Germany (at Fraunhofer ISE), Italy (PoliMi, Milan) and Australia (CSIRO) clearly demonstrate the international relevance and importance of the topic and will enhance the effectiveness of the international effort to combat climate change.

The building sector is one of the key consumers of energy in Europe today with an overall rising trend over the past 20 years. In order to achieve the current EU 20-20-20 goals or the targets set in the EU Energy Roadmap 2050, it is essential to renovate and retrofit these buildings and to replace inefficient heating systems based on fossil fuels or direct electric heating. The proposed heat pump technology offers a solution to both present and future challenges. The goal of the GreenHP project is to investigate and develop a new highly efficient heating system based on high-capacity air/water heat pumps for retrofitting multi-family houses and commercial buildings. This high power heat pump system will use an alternative refrigerant and will interact with large (renewable) energy systems, like the smart grids in particular, and integrate other renewable energy sources, like photovoltaic and solar thermal, as well as energy storage. In order to tackle the relevant scientific challenges, the consortium will employ a holistic approach covering research topics on the system integration level, heat pump unit and component level. This will representatively be done for high-capacity air/water heat pumps for retrofitting applications in cities. The technological solutions generated will reinforce the technological leadership of the European industry and strengthen the position in the increasingly strong and global competition in the market place. The integral approach of the GreenHP project requires a special consortium structure with project partners able to cooperate and exploit the project results on a common basis. The consortium, which includes Originals Equipment Manufacturers and research institutes only, will offer the Know-how on the unit design and the system integration in the public domain, available to all European Heat Pump manufacturers. By this, the GreenHP project will trigger competition to find the best solutions for the market and make a larger impact possible. The consortium is aware that this requires a strong dissemination to heat pump manufacturers but also to architects, urban planners, installers and end users. At the end of the project, a 30 kW lab scale pilot with a new unit design using alternative refrigerant and innovative components will be developed. In addition, it will be shown how this heat pump integrates into buildings and interacts with the smart electric grid. This will be the basis for many different applications for room heating and cooling as well as sanitary hot water production, as any solution between 30 kW and 100 kW will be possible. The consortium is confident that the implementation of the proposed concept will have a fundamental impact on the European Building sector by providing a new technical solution. Thus it will substantially contribute towards a sustainable European energy system.
