Signature Features
Everything You Need to Model, Compare & Optimize
Effortless Interface
Guided workflows replace complex spreadsheets. Input your project parameters and get results in minutes, not days.
Equipment Vendor Database
Pre-loaded with hundreds of real manufacturer models across all technologies -- CHP engines, boilers, chillers, heaters, and cooling towers -- with specs, performance curves, and cost data.
Climate & Weather Data
TMY (Typical Meteorological Year) hourly data for every city -- dry/wet bulb temperature, humidity, HDD/CDD -- driving accurate energy simulations without external weather research.
Utility Rate Structures
Multi-tier electric, gas, oil, and water tariffs pre-loaded per city -- TOU rates, demand charges, standby fees, and tiered billing. Supports 40+ currencies with auto-conversion.
Reference Load Profiles
8,760-hour reference load profiles for 30+ building types -- offices, hospitals, hotels, schools, industrial facilities -- with climate-adjusted heating, cooling, DHW, and electric loads.
Multi-Unit Simulation
Model multiple equipment units simultaneously. Compare manufacturers side-by-side with annual simulations at intervals as low as 5 minutes.
340+ Global Cities
Pre-loaded databases spanning 340+ cities across 24 countries and 75+ currencies. Each city includes weather, utility rates, load profiles, and financial defaults -- ready to use.
Lifecycle Cost Analysis
Full NPV, IRR, and payback calculations with study periods up to 50 years. Equipment CAPEX, energy costs, maintenance, and government incentives all factored in.
Professional Reports
Generate detailed technoeconomic reports with interactive charts, comparison tables, and multi-vendor analysis. Ready for stakeholder presentations and investment decisions.
