Almost as much energy is used for refrigeration, air conditioning and insulation worldwide as for transport or heating. On behalf of the Federal Ministry for Economic Cooperation and Development (BMZ), the GIZ ‘Proklima’ project has now been working for some 15 years to help introduce environment- and climate-friendly alternatives to ozonedepleting industrial gases (such as chlorofluorocarbon, CFCs) in partner countries. Proklima thus supports developing and emerging countries in fulfilling their obligations arising from the Montreal Protocol on Substances That Deplete the Ozone Layer.

This guideline aims to provide a general idea of the different steps when planning a conversion from an existing production system of domestic refrigerators to one that uses hydrocarbons, such as isobutane (R600a) or propane (R290), and the important aspects that small- to medium-size manufacturers need to consider.

RenoValue is a 2-year project funded by the Intelligent Energy Europe Programme of the European Union. The project will develop a training toolkit for property valuation professionals on how to factor energy efficiency and renewable energy issues into valuation practices, understand the impact of building performance and property values and advise their clients accordingly.
