Holz gehört zu den ältesten Werkstoffen dieser Welt und erfährt gerade im Bau eine Renaissance. Seit 2017 unterstützt das Ministerium für Heimat, Kommunales, Bau und Digitalisierung des Landes Nordrhein-Westfalen das „Bauen mit Holz”: Im Zuge der öffentlichen Wohnraumförderung des Landes Nordrhein-Westfalen oder über die Städtebauförderung des Landes und des Bundes wird das „Bauen mit Holz” finanziell angereizt.
Grundlage für den Einsatz von Holz im Bau ist die Bauordnung für das Land Nordrhein-Westfalen und die Muster-Holzbau-Richtlinie.
„Bei der Muster-Holzbau-Richtlinie ist es uns aus Nordrhein-Westfalen zusammen mit Bayern gelungen, die neue Richtlinie einem einstimmigen Beschluss zuzuführen. Über drei Jahre haben Fachleute aus 16 Bundesländern und andere Expertinnen und Experten daran gearbeitet, das ‘Bauen mit Holz’ in Deutschland zu vereinfachen und gleichzeitig den Brandschutz zu wahren. Mit der neuen Richtlinie wird der Anwendungsbereich für das Bauen mit Holz ausgeweitet. Zukünftig werden auch ‘Standardgebäude’ der Gebäudeklasse 5 wie Wohngebäude unterhalb der Hochhausgrenze in Holztafelbauweise errichtet werden dürfen. Bisher war dies nur in Massivholzbauweise möglich. Die Änderung macht den Bau kostengünster und stärkt die serielle Vorfertigung. Des Weiteren wird der Anwendungsbereich der Richtlinie auf Sonderbauten ausgeweitet. Auch ein höherer Anteil von sichtbaren Holzoberflächen wird zugelassen. Auf die neue Richtinie haben viele Bauherrschaften und Planerinnen und Planer gewartet. Jetzt gilt es, die neue Richtlinie in das nordrhein-westfälische Recht einzuführen. Damit verschaffen wir dem Holzbau in Nordrhein-Westfalen weiteres Wachstum. Wir wollen das Bauen in Nordrhein-Westfalen noch einfacher, schneller und umweltschonender machen. Als nachwachsender Rohstoff leistet Holz einen wegweisenden Beitrag zur ressourcenschonenden und nachhaltigen Entwicklung des Bauwesens. Wir sind startklar und brauchen jetzt noch das ‘go’ der Europäischen Kommission,” so Ina Scharrenbach, Ministerin für Heimat, Kommunales, Bau und Digitalisierung des Landes Nordrhein-Westfalen.
Nach dem Beschluss der Bauministerkonferenz ist die neue Muster-Holzbau-Richtlinie der Europäischen Kommission zur sogenannten Notifizierung vorzulegen. Dieser Prozess dauert zwischen drei und sechs Monate. Danach kann die neue Muster-Holzbau-Richtlinie als Technische Baubestimmung in Nordrhein-Westfalen formal eingeführt werden.
Für die Übergangszeit hat das Ministerium für Heimat, Kommunales, Bau und Digitalisierung des Landes Nordrhein-Westfalen auf der Grundlage von § 17 Absatz 4 BauO NRW 2018 per Erlass festgelegt, dass für die durch den Anwendungsbereich der neuen Muster-Holzbau-Richtlinie genau begrenzten Fälle eine Bauartgenehmigung nicht erforderlich ist, wenn für diese Fälle bei der Planung, Bemessung und Ausführung die von der 145. Bauministerkonferenz beschlossene Fassung der Muster-Holzbau-Richtlinie beachtet wird, da Gefahren im Sinne des § 3 Absatz 1 Satz 1 BauO NRW 2018 unter dieser Voraussetzung nicht zu erwarten sind.
Die Richtlinie regelt die Bauweise zur Errichtung feuerwiderstandsfähiger Bauteile für größere Mehrfamilienhäuser (Gebäudeklassen 4 und 5), die Anforderungen zur Planung von Holzbauten sowie die Anordnung von brandschutztechnisch wirksamen Bekleidungen aus Holz. Bei der Ausweitung der Holztafelbauweise auf Gebäude der Klassen 4 und 5 wird beim Bau Material eingespart und ist damit wirtschaftlicher als die bisher nur mögliche Massivholzbauweise. Bei der Holztafelbauweise handelt es sich um eine verbreitete Holzbauweise von Fertighäusern, bei der Bauteile vorgefertigt und beim Hausbau zusammengefügt werden.

"A year ago, Germany's largest cooperative building project was on the brink of collapse; on Thursday, the Möckernkiez is celebrating its topping-out ceremony. Just under a third of the 470 apartments at Gleisdreieck are to be ready by the beginning of the year - much later and more expensive than planned."
All apartments are scheduled to be ready for occupancy by July 1, 2018.

There is a shortage of housing in Europe's conurbations; Germany alone lacks about 1.5 million residential units (WE). For this reason, the federal government has decided to build 400,000 WE annually. At the same time, the federal government's climate protection plan foresees a significant decrease in building emissions from 209 million to 67 million tonnes of CO2-equivalents by 2030, which would correspond to an emission reduction of 68 % since 1990. Other European countries have also committed to implementing far-reaching climate protection targets. Against this background, many of those involved in construction are increasingly relying on wood as a renewable building material, in addition to energy-efficient construction and the use of renewable energies.
The Construction cost study on large timber housing estates and quarters in Europe (short Wooden housing study), financed from funds of the funding programme FUTURE CONSTRUCTION of the Federal Ministry of Transport, Building and Urban Affairs (BMWSB) and based at the Rottenburg University of Applied Sciences (HFR), systematically researches and records those projects in timber and timber hybrid construction that have already been realised or are currently in planning. In the process, the construction costs of the buildings are analysed as well as the motives of the investors and clients to build with wood. Another goal is to show how timber construction methods can be further established in the segment of housing estates and urban districts in order to expand the range of large-volume housing projects with an environmentally and climate-friendly variant.
The first results of the study will be presented at the 15th Congress Efficient Building with Wood in Urban Areas on 19 October 2022 in Cologne presented. So far, 118 large-scale housing projects with more than 100 units have been identified across Europe by the HFR researchers, 47 of which are located in Germany. Final results will be presented at the beginning of December at the 26th International Timber Construction Forum in Innsbruck presented on 30 November 2022 and also published in a brochure by the Information service wood published.

Funding for solar houses with large photovoltaic and solar thermal systems for heat, electricity and mobility remains consistently high
"Solar houses with large photovoltaic and solar thermal systems for the climate-friendly generation of electricity and heat are not affected by the changes in the amended Renewable Energy Sources Act." Rainer Körner, 2nd Chairman of the Sonnenhaus-Institut e.V., points this out. Since the EEG 2017 was passed by the Bundesrat and the Bundestag on 8 July 2016, it has been strongly criticised from various sides. "Even if certain changes will certainly not lead to rapid progress in the energy transition and climate protection, the impression must not be created now that solar systems are generally no longer worthwhile," says Körner. The managing director of the Heilbronn-based construction company KHB-Creativ Wohnbau has been vice-chairman of the Competence Network for Solar Construction since November 2015. "For solar houses, the subsidy remains constantly high." For photovoltaic systems with an output of up to 10 kilowatts, nothing will change in the EEG 2017. In this size range, these plants will still be exempt from participation in the EEG apportionment. Regardless of the EEG, solar thermal systems on solar houses will continue to receive very good support from the federal government's Market Incentive Programme (MAP).
Savings through solar energy for electricity and heat
In solar houses with photovoltaics and solar thermal energy, the residents benefit in several ways. In the area of electricity generation, they can generate solar electricity at a price that is lower than the purchase price from the energy supplier and use it themselves. Depending on the size of the solar power system, energy consumption and other parameters, up to about 30 percent of the solar power can be consumed without energy storage. With battery storage, it can easily be up to 70 or 80 percent of household electricity. The solar electricity can also be used to generate heat with the help of a heating rod or a heat pump. And it can charge an electric vehicle. This means that solar house owners save on energy costs by using their self-generated solar power, and they also receive compensation for the surplus solar power that is fed into the public grid.
In the area of heat supply, the focus is on gaining purchasing power through savings. With large solar systems, more than half of the heating energy demand in solar houses is solar-generated. "With solar coverage rates of 60 or 70 percent, the savings for oil or gas, which you don't have to buy, are considerable," Körner explains.
Solar house as an individual contribution to climate protection
"But the all-embracing bracket is climate protection," he adds. "The large solar plants ensure that energy for heat, electricity and mobility can be produced with extremely low CO2 emissions and without coal, oil and natural gas." And that, after all, is ultimately the goal of the energy transition and also of the EEG, says Körner. Solar houses also contribute to grid stabilisation, since the energy they produce and consume themselves does not use the grid.
However, one legal innovation is also relevant for the builders of solar houses. As a result of the Digitalisation Act, which was also passed at the beginning of July, photovoltaic systems with an output of more than seven kilowatts must be equipped with a smart meter measuring device. "For a single-family house with average electricity consumption, however, a smaller photovoltaic system is completely sufficient to achieve a reasonable self-sufficiency rate," says Körner.
The Sonnenhaus-Institut has prepared sample calculations for the subsidies for large solar heating systems, which are handled by the Federal Office of Economics and Export Control (BAFA). "The subsidy rates for large solar heating systems have never been as high as they are today," Körner emphasises. Building owners can receive up to half of the investment costs for solar collectors as a BAFA grant. "With a solar house, every builder and renovator can make a contribution to climate protection - and thus make themselves a bit independent of energy suppliers and political framework conditions."
