Greenhouse Energy Efficiency Calculator
Unlock instant savings by modeling real-world heat-loss, fuel prices, and payback periods before you spend a cent. Our 2025-ready calculator translates R-values, boiler efficiencies, and thermal-screen stats into clear dollars-and-cents-so you can invest where it matters most.
2025 Energy-Saving Spotlight
- Hybrid heat-pump + boiler loops: Air-to-water heat pumps now deliver COP 3.6 down to -10 °C, with boilers auto-covering extreme cold snaps.
- Next-gen thermal screens: Albedo-boosted, diffuse fabrics bounce summer heat and trap 40% more night warmth than 2022 models.
- Low-E polycarbonate glazing: Factory-applied coatings cut IR losses by 30% without sacrificing PAR light.
- Smart zone controls: Wireless sensors feed AI algorithms that tweak set-points in real time-saving 10-25% on HVAC energy.
- Heat-recovery ventilators (HRVs): Capture up to 70% of exhaust heat while maintaining fresh airflow.
