   - By motivating the construction industry to set the focus on Energy efficient retrofit NOW! Every manufacturer of construction products can contribute to its success with their [[certification:passive_house_suitable_components|(optimised!) product]]. Often, it is not necessary to make any huge adjustments - but some know-how is needed, which is already available in the published (and freely accessible) work relating to [[:certification:enerphit|EnerPHit ]].\\ \\
   - {{ :picopen:stroh1.jpg?100|}} By creating additional capacities for the production of insulation materials from sustainable raw materials, e.g. for [[https://passipedia.de/planung/stroh_als_waermedaemmung|thermal insulation using straw (German page)]]. There is more than enough "material" for this purpose - and experience has shown that it can contribute a very large part to thermal protection measures, especially in the case of one to two storey buildings. This would then constitute a double contribution towards sustainability.\\ \\

Jobs can be created here on a significant scale. Again, this would be a double contribution towards sustainability.\\ \\

   - [[efficiency_now:immediate_measures|Immediate measures]] can often be carried out on a self-help basis. With good instructions and a "practical set-up", the essential work processes can be learned in a few days - maybe not by everyone, but potential certainly exists here. This may contribute to success, especially in the first year, when things can get particularly difficult and everything has to be done fast.\\ \\
-  - {{ :picprivate:wpumpe_kk.jpg?200|}} The switch to heat pumps can also be accelerated. This is certainly the most reasonable alternative to natural gas in terms of technical building systems - because renewably generated electricity can be used here directly and energy efficiently for heating via the existing power grid ((Heat pumps lead to less greenhouse gas emissions than any form of fossil-based heating. In the course of a few years, the difference will become more and more significant, an ever increasing share of electricity will be generated with renewable energy. Also, every house owner can contribute by installing a PV system in addition.)). Besides, this is easier, more cost-effective and environmentally compatible if the building is already upgraded in terms of energy efficiency; however, the reverse order may also work: a boiler that already needs to be renewed now can be replaced by a heat pump even in an existing building, possibly for bivalent operation at first. But as modernisation progresses, the heat pump can then assume the entire heating load - and that with an increasingly higher share of wind power from the power grid in the future, until this becomes a full renewable supply system in 15 to 20 years.\\ \\

-  - {{ :picprivate:raumklima1.jpg?200|}}  There is a way in which the significant potential of additional mini heat pump units can even be made available: i.e. modern minisplit air conditioning units. These can be installed easily and economically- and can almost completely cover the heating in autumn and spring((suitable models are available on the market)) in the transitional period, helping to save gas. In case of emergency they can even heat a single room in the winter - with a higher output than a fan heater but only about one-third of the electricity consumption. We have described this in more detail here: [[https://passipedia.de/technik/raumklimageraet|heating with an air-conditioning unit (German page).]]\\ \\

   - And of course, [[https://passipedia.de/sofortmassnahmen#eigene_solarenergie|electricity generating photovoltaic systems (German page])]] should be on as many roofs as possible! These already provide electricity more cheaply today than generated by fossil fuels. A whole range of other surfaces are also suitable for the expansion of PV. Even people living in rented homes can generate some electricity with 'balcony-systems' and save some $$ in this way ((However, for the sake of avoiding disappointment, how much this will contribute must be depicted realistically: in the main winter months the heating contribution will not be noteworthy with this, but nevertheless it still makes sense because it saves fossil energy, especially in summer.))\\ \\
