Wärmepumpe oder Gas?

Die Wärmepumpe ist 2026 in Neubau und gut gedämmtem Altbau fast immer die wirtschaftlich bessere Wahl — bei einem COP ≥ 3 und KfW-Förderung bis zu 70%.

Wärmepumpe im Altbau — funktioniert das?

Ja, wenn die Vorlauftemperatur unter 55 °C bleibt. Entscheidend: Heizkörperdimensionierung und Dämmstatus — nicht das Baujahr.

Wärmepumpe mit PV kombinieren?

Ja — Eigenverbrauchsanteil von 60–80 % senkt Betriebskosten um 30–50 %. Amortisation typisch 10–14 Jahre inkl. Förderung.

Holzfaserdämmung oder EPS?

Holzfaser kostet 20–40 % mehr, liefert aber 3–5× besseren sommerlichen Wärmeschutz und eine positive CO₂-Bilanz — bei EPS ist sie negativ.

Lehmputz oder Gipsputz?

Lehmputz kostet ca. 20–40 €/m² mehr, reguliert Feuchte aktiv und bindet VOC — messbar bessere Raumluftqualität für Allergiker und Kinder.

Ist Strohbau sinnvoll?

Ja — mit ETA-Zulassung, zertifiziertem Verarbeiter und korrektem Feuchteschutz. Brandschutz ist gelöst; Herausforderung ist die Fachkraft-Verfügbarkeit.

Holzhaus oder Massivhaus?

Holzhaus ist 15–25 % schneller fertig, CO₂-negativ und modular erweiterbar. Massivhaus punktet bei Schallschutz und lokaler Handwerker-Verfügbarkeit.

Sanieren oder Abriss + Neubau?

Sanierung erzeugt 2,4× weniger graue Emissionen als Neubau. TCO-Vorteil in 80 % der Fälle — außer bei Bausubstanzmängeln unter Bodenplatte.

Kita in Holz oder Beton?

Holz-Kita ist 25–30 % schneller fertig, KfW-kommunal-förderbar und bei Holzbauoffensive-Ländern bevorzugt — Brandschutz HO4 ist bei mehrgeschossigem Bau zu prüfen.

Was kostet rückbaubares Bauen wirklich?

Mehrkosten: 8–15 % gegenüber konventionell. Mit KfW+QNG-Förderung: 3–7 % Netto-Mehrkosten. TCO über 50 Jahre: rückbaubarer Bau mit nachwachsenden Rohstoffen 18–22 % günstiger.

KfW 40 NH oder KfW 40?

KfW 40 NH (mit QNG-Siegel) bringt 12,5 % mehr Tilgungszuschuss — lohnt sich ab ca. 200.000 € Kreditvolumen. Mehraufwand: ca. 3.000–5.000 € für Zertifizierung.

In welcher Reihenfolge Förderantrag stellen?

BEG-Antrag muss VOR Auftragsvergabe gestellt werden — nicht vor Baubeginn. Diese Verwechslung kostet jährlich Tausende Bauherren ihre KfW-Förderung.

BAFA oder KfW — was ist besser?

BAFA (BEG-EM): Einzelmaßnahmen, direkter Zuschuss, keine Kreditaufnahme. KfW (BEG-WG): Komplettsanierung, günstiger Kredit + Tilgungszuschuss bis 45 %. Kombi möglich.

Gilt die Solardachpflicht für mein Gebäude?

Ja, bei Neubau in 11 Bundesländern und Dachsanierungen ab bestimmten Schwellenwerten. Ausnahmen: Dachneigung <15°, Verschattung, Denkmalschutz.

Was ist GreenBuild360?

GreenBuild360 ist ein Planungs- und Bauunternehmen für wohngesunde, rückbaubare Gebäude mit Holz, Lehm, Hanf und Stroh. Mit 30+ Jahren Erfahrung in der D-A-CH-Region. Auf der Wissensplattform teilt das Unternehmen, welche Lösungen es selbst baut — mit Quellen aus GEG, DIN, KfW, EPD und Fraunhofer-Studien.

Baut GreenBuild360 selbst oder ist es nur eine Plattform?

GreenBuild360 ist ein Bauunternehmen — wir planen, entwickeln und bauen selbst wohngesunde, rückbaubare Gebäude aus nachwachsenden Rohstoffen. Die Wissensplattform zeigt transparent, wie wir planen und welche Lösungen wir empfehlen, mit belegbaren Quellen.
