The CogenS™ Technoeconomic Modeling Suite
A Comprehensive Set of Tools
For every stage of your project lifecycle
Thermal Systems Suite
Hot Water Heaters
Electric, gas, heat pump, and solar domestic hot water heaters. Complete manufacturer selection and lifecycle cost analysis.
Boiler Systems
Commercial and industrial boiler systems. Hot water and steam configurations with thermal storage and manufacturer-specific data.
Chiller Systems
Commercial and industrial chiller systems. Air-cooled and water-cooled configurations with full lifecycle analysis.
Cooling Towers
Commercial cooling tower systems. Crossflow and counterflow configurations with performance modeling.
Power Systems Suite
EV Charging
Fleet and public EV charging infrastructure. DC fast and Level 2 chargers, traffic and dwell modeling, with full feasibility (NPV, IRR, payback).
Battery Energy Storage
Behind-the-meter battery energy storage (BESS). LP dispatch for demand-charge management, arbitrage, and PV co-optimization with lifecycle cost and resilience.
Microgrid
Multi-DER microgrid optimization. Co-dispatch CHP, solar PV, and battery storage with grid interaction, peak shaving, and outage resilience.
On the Roadmap
Geothermal HVAC Systems
Closed-loop ground-source heat pumps (water-to-water & water-to-air) on vertical borefields — 20-year ground-temperature drift with boiler/CHP and absorption-chiller balancing to keep the well in annual thermal equilibrium.
Green Hydrogen Systems
Green hydrogen & electricity from renewables — electrolyzers, fuel cells, compressed-gas and metal-hydride storage, and H₂ blending into CHP.
CogenS Pathfinder
Multi-technology portfolio and district energy optimization — the lowest-cost, lowest-carbon tech mix across electric, heating, cooling & DHW.

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, cooling towers, batteries, and EV chargers -- 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. Optional RateAcuity add-on pulls live US/Canada tariffs from current utility filings. Supports 75+ 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.
DER Co-Optimization
Co-optimize on-site solar PV, battery storage, and thermal storage alongside CHP and boilers with an hourly dispatch engine that minimizes lifecycle energy cost.
Sub-Hourly Simulation
Run annual simulations at 15, 20, 30, or 60-minute timesteps. Capture demand spikes, dispatch dynamics, and demand-charge exposure that hourly models miss.
Resilience & Outage Analysis
Size battery and CHP capacity for grid outages -- model critical-load coverage, outage duration, and the cost of unserved energy for resilient, islandable designs.
Multi-Unit Simulation
Model multiple equipment units simultaneously. Compare manufacturers side-by-side with annual simulations and lead-lag staging.
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 & Financial Modeling
Full NPV, IRR, payback, and TCO with study periods up to 50 years -- plus Energy-as-a-Service deal modeling (PPA, tolling, shared-savings) from both owner and provider perspectives.
Professional Reports
Generate detailed technoeconomic reports with interactive charts, comparison tables, system diagrams, and multi-vendor analysis. Ready for stakeholder presentations and investment decisions.
