        Funding programme for "Heat Network systems 4.0"

        Since July 2017, the Federal Government has been funding heat network operators with the funding programme "Model Project Heat Network Systems 4.0" with the aim of either constructing modern low-temperature heat networks with a high proportion of renewable energies and waste heat (at least 50 %; "4th Generation Heat Networks") or transforming their existing heat networks into such modern, low-CO2 networks. The funding programme not only supports individual technologies and components, but the entire heat system. Funding will be provided for the costs of feasibility studies that examine the feasibility and cost-effectiveness of the planned 4.0…

        Danish Building Regulations BR10

        The BR10 is a performance-based code that requires a mandatory energy frame calculation to establish maximum energy demand for residential and non-residential buildings. The code addresses all thermal envelope requirements and energy-using efficiency standards in the calculation, including, heating, cooling, ventilation, hot water, lighting (only non-residential), heat recovery and conversion and distribution losses.

        New Zealand Warmer Kiwi Homes

        The Warmer Kiwi Homes programme in New Zealand, launched in its current form in 2018, provides grants that cover 80% of the cost of insulation and clean heating for low-income households. New Zealand’s Energy Efficiency and Conservation Authority (EECA) administers the programme. Qualifying homes must be owner-occupied, built before 2008, and either be situated in an area that is classified as low-income or have one occupant that is a holder of a Community Services Card. EECA maintains a list of approved energy products and a panel of registered energy service providers that deliver the measures and…

        Building Renovation Program (Das Gebäudeprogramm, Le Programme Bâtiments)

        The Building Programme has been implemented to encourage energy efficient renovation of old buildings with the purpose of lowering greenhouse gas emissions (mostly CO2). The Building Programme is executed together with almost all of Switzerland's cantons, who encourage the use of renewable energy, waste heat, improved building technology and also total building renovation. A small portion of the CO2-levy from the use of fossil fuels in stationary applications (Fr. 30 million per year) is administered directly by the Confederation to encourage the direct use of geothermal energy for heating purposes in buildings provided their greenhouse gas emissions (particularly…
