AI Engineering Assistant
An Assistant That Has Read Your Project.
Ask why your payback moved, what an input does, or what a report figure is made of. The assistant built into CogenS™ reads your saved inputs, your results and the model’s record of your latest run — then explains the answer in plain engineering terms, with your numbers.
Explains your results. Traces a surprising number to its cause — a default that was applied, a unit read differently, a value held at a physical limit.
Answers with your data. Your project, your rates, your results — not a textbook range.
Private to your account. It reads only your own projects, and never invents a figure the model didn't produce.
Why is my annual gas cost so much higher than our actual bills?
The gas rate on this project was left blank, so the run priced every unit of gas at the default rate for your city rather than your contract rate.
The fuel the boilers burned is consistent with your load and their efficiency — it is the price per unit driving the cost. Enter your contract rate on the Utility Rates page and run the model again.

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 gas-genset 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.
