Engineer-Grade Technoeconomic Analysis Guides
Practical guidance on sizing and evaluating thermal, power, storage, and cogeneration systems. Mirrors the workflow inside the CogenS™ platform, with no screenshots — just specs, methods, and design steps.
Thermal Systems
Thermal Systems Guides
Heating and cooling infrastructure — boilers, hot water heaters, chillers, and cooling towers. Lifecycle cost analysis, multi-vendor comparison, and 8,760-hour simulation.
Thermal Systems Technoeconomic Analysis Guide
Suite-level overview: how to evaluate heating, cooling, and DHW systems together, with shared assumptions and consistent financial framing.
Read guideHot Water Heater Design & Sizing
Electric, gas, heat-pump, and tankless DHW system sizing. Storage vs on-demand. Lifecycle cost across fuel types.
Read guideBoiler System Lifecycle & Design
Steam vs hot water, condensing vs non-condensing, multi-unit sequencing, TES co-dispatch, and IHWH integration.
Read guideCommercial Chiller Design & TEA
Air-cooled vs water-cooled vs absorption, part-load behavior, multi-vendor comparison, and full lifecycle cost analysis.
Read guideCooling Tower Selection & Lifecycle Cost
Open vs closed circuit, counterflow vs crossflow, fan and approach selection, water-treatment costs.
Read guidePower Systems
Power Systems Guides
Electrification, storage, and on-site power — battery energy storage, EV charging, and multi-DER microgrids with on-site gas generation for data centers and AI, plus resilience and Energy-as-a-Service.
Battery Energy Storage — Sizing & Lifecycle TEA
Size and dispatch behind-the-meter batteries against a real tariff — demand-charge management, arbitrage, and solar co-optimization — with degradation and resilience in the business case.
Read guideEV Charging Infrastructure — Fleet & Public TEA
Fleet and public charging feasibility: utilization, demand charges, and the business case for ICE-replacement savings or public session pricing.
Read guideMicrogrid DER Optimization & Resilience
On-site gas generation (fuel cells, RICE engines, gas turbines), solar, and storage for behind-the-meter power — sized for data-center/AI load growth, everyday savings, and outage resilience.
Read guideDER Co-Optimization & Energy-as-a-Service
Co-optimize solar, storage, and thermal assets against a tariff, then structure the deal — building-owner vs provider — with the right Energy-as-a-Service contract.
Read guideEnergy-as-a-Service Deal Structures
The four EaaS contracts — energy concession, capacity tolling, shared-savings ESA, and on-site PPA — with fee mechanics, risk allocation, and a dual-MARR solve for both parties.
Read guideCogeneration
Cogeneration Guides
Combined Heat and Power feasibility, design, and economics — from prime-mover selection through DER optimization and waste-heat capture.
CHP Technoeconomic Analysis Guide
When to consider CHP, how to size it, and how to assess financial viability. Covers reciprocating engines, gas turbines, microturbines, and fuel cells.
Read guideCHP System Design & Feasibility — Module Guide
Hands-on walkthrough: load profile matching, prime-mover selection, DER co-optimization (Solar/BESS/TES), hydrogen blending, and EaaS waste-heat revenue.
