Reducing CO\u2082 emissions, the energy transition, climate change \u2013 these are all buzzwords that have gained increasing importance in recent years. In the past few months, also driven by the global political situation, the topic of the energy transition has become even more urgent. What can every property owner do to make their own contribution, lower energy costs, and implement energy-efficiency measures through building renovations?<\/strong><\/p>\n

The individual refurbishment roadmap (iSFP) \u2013 what exactly is that?<\/h2>\n

When planning to renovate your property, you should ideally to a certified energy consultant from the Federal Office for Economic Affairs and Export Control<\/strong>, abbreviated as BAFA. The expert will work with you to develop a comprehensive renovation roadmap<\/strong>, which contains all measures to To optimize your residential building economically and energetically<\/strong>. Of course, it is also important to examine the sequence of the required construction measures very closely. Installing a new heating system first and then carrying out extensive insulation work or replacing windows naturally makes no sense.<\/p>\n

The refurbishment roadmap details both the Current state<\/strong> as well as the desired Target condition of the building<\/strong> documented. Using a color-coded traffic light system, you can see at a glance what the energy state of the property is. For example, dark red stands for unrenovated buildings, yellow for partially renovated ones, and green for new builds that meet all legal requirements.<\/p>\n

Whether the property owner chooses to have all renovation measures carried out or only individual steps is entirely up to them and, of course, depends on their financial resources. Those who obtain an energy consultation and, as a next step, have the measures recommended in the renovation roadmap carried out can apply for subsidies and, once the work is completed, even receive an additional grant of 5 %. Therefore, anyone who decides to renovate their property is also choosing, due to the energy-saving potential, to significant enhancement of his property<\/strong>.<\/p>\n

The creation of the individual renovation roadmap \u2013 the specific process<\/h2>\n

The homeowner's first step in having an individual renovation roadmap created is to contact the energy consultant. For the beginning, a phone call is sufficient. In order to provide optimal advice, the expert needs as many documents about the residential building as possible: floor plans, the existing energy performance certificate, and ideally also documents on energy costs such as electricity or heating. As the next step, an on-site appointment is scheduled to go into detail.<\/p>\n\n\t
