[en] The more strict energy performance standards in the Netherlands require increasingly creative solutions to realize clean air and reduced energy consumption, in particular for small and medium-sized enterprises and industries in relation to the long-term energy efficiency agreements (MJA) between the businesses and industries and the Dutch government and environmental regulations. Gas technology is an option to save energy and to reduce CO2 emission. However, the quality of gas technology is not yet applied on a large scale, because energy conservation is seldom given enough priority, payback periods are long, and appropriate gas appliances is either not available or insufficiently known. A seminar will be held on the title subject December 10, 1998, organized by the Netherlands Agency for Energy and the Environment (Novem)
