Long-term strategies to 2050 for any unique building asset considering all aspects of renovations for asset and construction management
  • 3+ strategy options from least-cost to least-CO₂
  • Capex and Opex budgets
  • Rental projections and rental pass-on
  • Operational and embodied CO₂ emissions (Scopes 1-3)
  • Data-driven stranded asset risks
  • Policy compliance and available incentives
  • 25+ materials and technologies considered for all components
  • Energetic renovations "all at once" for efficiency and supply
  • Retrofitting energy demand simulations with EnergyPlus
  • Building extension opportunities
  • Non-energy components (e.g. kitchens, baths, floors, etc.)
  • Coupling projects to reduce cost

Digital twin 3d models and solar design

Accurate component areas and building retrofitting simulations
Integrated 5-zone solar PV design with tilt

Any asset and energy system composition

Attached buildings with a shared energy system
Separate buildings with multiple energy systems

Minimal data input with maximum customizability

Simplify your strategy development process. Our platform delivers intelligence with minimal data input by leveraging data-driven processes.


Total sustainability: portfolio budgetary and CO₂ pathways considering asset-level granularity with minimal planning cost
  • Smooth and limit Capex budgets
  • Benchmark asset performance
  • Bottom-up Net Zero CO₂ pathways (beyond CRREM)
  • Limit number of projects per year
  • Evaluate risks across assets
  • Prioritize "low hanging fruit" vs. "hard to decarbonize"
  • Test any potential developments (e.g. natural gas price)
  • Future policy scenarios for 10+ policy instruments
  • Robust risk-conscious strategies
  • Technology exposure and reliance

Portfolio investment planning for the digital age

Smooth Capex and assure consistent dividends with intelligent alerts
Bottom-up CO₂ pathways towards "whole life" Net Zero Scope 1-3
Benchmark asset strategies to flag "hard to decarbonize" vs. "low hanging fruit" and stranded assets
