Sources: 4. Developments: 2. Developments in the HVAC and energy efficiency sector highlight a focus on integrated heating, ventilation, and cooling solutions for residential and commercial use. Initial reports emphasize the importance of comprehensive energy management, including the installation of heat pumps, ventilation, recuperation systems, and photovoltaic installations. Experts note that efficiency depends on building insulation, window quality, and precise temperature regulation to ensure devices operate within optimal modes. Subsequent technological advancements include the introduction of scalable air/water heat pump series using R290 refrigerant. These systems are designed for both new constructions and the modernization of older buildings, capable of reaching flow temperatures up to 75 °C. Complementary building technology developments include high-efficiency DX ventilation units and mono-split climate systems designed to operate in temperatures as low as −12 °C. ## Timeline ### 2026-09-06: Dimplex and S-Klima unveil new building technology solutions Dimplex and S-Klima showcase new building technology, including scalable R290 heat pump series and advanced ventilation systems for residential and commercial use. 2 sources. https://clstr.news/cluster/dimplex-and-s-klima-unveil-new-building-technology-solutions ### 2026-08-23: HVAC and energy efficiency solutions for residential and commercial sectors Climacore and VYKUROVANIE24 provide specialized services in HVAC, heat pumps, photovoltaics, and energy-efficient heating solutions for homes and businesses. 2 sources. https://clstr.news/cluster/hvac-and-energy-efficiency-solutions-for-residential-and-commercial-sectors --- Cite as: HVAC and energy efficiency technology developments.
