We stand together
The current crisis highlights the urgency to end our dependency on fossil fuels. The Passive House Institute has set up a special section on Passipedia as a call to action. It provides information about measures that can help anyone reduce their gas and oil consumption. “Efficiency NOW!” describes easily implementable efficiency measures, which are crucial for achieving meaningful energy savings! The section also covers sufficiency measures and more. Watch this space as it grows!
Due to war and economic conflicts, there is currently a lot of pressure concerning maintaining an affordable, fair and environmentally friendly energy supply in the coming years. For over 25 years, the Passive House Institute has been developing solutions to avoid and mitigate energy crises. The Passive House concept itself is one such way of improving energy independence. Perhaps more importantly, the Institute has worked with manufacturers to certify components developed for this purpose. These components are already available for use in new builds and retrofits of existing buildings. The Passive House Institute has also developed the EnerPHit concept for retrofitting existing buildings to a high level of energy efficiency. It can be applied as a deep retrofit or step-by-step.
When rapid implementation is required, other approaches are worth considering. We will present these immediate responses to the energy crisis on these “Efficiency Now!” pages. This information is divided into the following sections:
In widely available informational materials, the effectiveness of all these measures is often significantly underestimated. Particularly in combination, these measures can save considerable amounts of heating energy - and thus help compensate for the fuel supply deficit.
The engineers and architects of the Passive House Institute have been working on the development, quality assurance and monitoring of new builds and retrofits for many years. Armed with this knowledge, they have a treasure-trove of expertise, methods and tools, which they happily share under the “Efficiency Now!” banner for public use.
Energy efficiency measures for buildings have a significant advantage: they can be designed and implemented comparatively quickly. When done correctly, these measures provide long-term energy and financial savings, improve the building structure and its durability, help facilitate the transition to renewable energy and provide improved comfort (even in a crisis). These measures contribute to climate protection and a sustainable future by unlocking the potential for an all-renewable energy supply for everyone significantly faster than without energy efficiency measures.
Our heating energy demand is still high because our politicians, economists, and society have always assumed that energy will be and remain cheap. The energy efficiency of new buildings and deep retrofits of the existing building had lagged far behind today's economically viable targets. To change that now in the short term is more painful than it would have been if the EU's EBPD (nearly zero energy building) as specified for 2020 had been consistently implemented. However, as our concrete suggestions show, it's still possible.
