It's the Windows, Stupid! Windows are a key part in the façade and prefabrication of a window module comprising various functional elements such as shading devices, insulation and airtightness provides leverage for rapid and cost-effective site work. A commercial renovation system on this principle is presented. |

News about windows and glazing The U-value of glazing units depends on the outdoor temperature. This dependence decreases in line with decreasing thickness of the space between panes and the number of panes. Vacuum glazing units are not affected by this effect; however, they require new concepts for window frames. One such window has already been certified.

Energy and CO2 across the lifecycle: The contribution of building materials and design Buildings that consume little energy during their lifecycle, act as carbon sinks, are durable and cost-effective, are sustainable and help the energy transition. Carefully selected building materials and design can make an important contribution to this goal. |

Extractor hoods for domestic kitchens – does extract air work in Passive Houses? Extractor hoods remove cooking grease and odours from the air. This often comes with considerably higher energy consumption, particularly in the case of extract air hoods. Our study compared the effectiveness and efficiency of exhaust air extractor hoods and recirculation air extractor hoods. |

Domestic Air to Water Heat Pumps: Detailed Performance Monitoring Detailed monitoring of an air to water heat pump for one year illustrates challenges of ideal control for maximum energy efficiency. Energy use is quantified for controls, circulation pump, and defrost cycles. The impact of short cycle operation is also estimated. |

Summary of important results from AkkP 59 "Building Automation" The 59th meeting of the Research Group for Cost-effective Passive Houses was able to refine many aspects of building automation in Passive Houses. The functional requirements should be met with the help of cross-trade systems based on actual indoor temperatures, using a minimum amount of auxiliary energy. |
