What is the Hysopt Feasibility?

Hysopt Feasibility helps HVAC engineers and MEP consultants reach client-ready HVAC feasibility decisions in just 1–2 hours instead of weeks.

Generate and compare multiple HVAC concepts using minimal inputs, evaluate CAPEX, OPEX, CO₂ and key system sizing decisions, then deliver a professional HVAC Feasibility Pack with system variants, KPIs, assumptions and engineering evidence—giving clients confidence in the recommended solution before detailed design begins.

Powered by Hysopt Designer and Simulator, every feasibility study is built on the same physics-based hydronic HVAC digital twin used throughout detailed design and dynamic simulation, ensuring decisions are based on engineering evidence rather than assumptions.

Frequently Asked Questions

What is an HVAC feasibility study?

An HVAC feasibility study compares multiple HVAC system concepts before detailed design to identify the best balance of performance, cost and carbon. Hysopt Feasibility helps engineers generate, compare and defend these decisions using a physics-based digital twin.

What is HVAC optioneering?

HVAC optioneering is the process of evaluating multiple HVAC system concepts before committing to a final design. Hysopt lets engineers compare alternatives using consistent CAPEX, OPEX, CO₂ and technical performance metrics to identify the best solution.

Why use a physics-based digital twin for HVAC feasibility?

A physics-based digital twin predicts how HVAC systems will behave before construction, giving engineers greater confidence in concept selection, equipment sizing and performance claims than spreadsheet-based calculations alone.

How is Hysopt Feasibility different from Excel?

Unlike spreadsheets, Hysopt keeps every HVAC concept connected through a single physics-based digital twin. Engineers can update one model, compare alternatives instantly and avoid manual recalculations, copy-paste errors and inconsistent assumptions.

Is Hysopt suitable for tender-stage HVAC design?

Yes. Hysopt Feasibility was built for tender and early design phases where engineers need to compare concepts quickly, defend recommendations and present clear evidence before detailed engineering begins.

Can Hysopt support retrofit and decarbonisation projects?

Yes. Hysopt Feasibility is widely used for retrofit, electrification and decarbonisation projects, helping engineers compare replacement strategies and justify investments with transparent technical and financial analysis.

Which building types can Hysopt Feasibility be used for?

Hysopt supports commercial buildings, hospitals, education campuses, residential developments, data centres, district heating and cooling networks, industrial facilities, and retrofit or decarbonisation projects.

Can Hysopt compare heat pump systems?

Yes. Hysopt Feasibility allows engineers to compare multiple heat pump concepts, evaluate sizing strategies, analyse buffer vessel requirements and understand the impact on energy use, operating costs and CO₂ emissions.

What information do I need to start an HVAC feasibility study?

Most projects only require estimated heating and cooling loads, operating schedules, temperature or ΔT targets, project constraints such as grid capacity or plant space, and client objectives for CAPEX, OPEX or CO₂. Hysopt then generates and compares multiple HVAC concepts using its physics-based digital twin.

Can an HVAC feasibility study really be completed in 1–2 hours?

Yes. Hysopt Feasibility is purpose-built for rapid HVAC optioneering. Pre-built HVAC templates, minimal project inputs and automated comparison tools allow engineers to evaluate multiple concepts and generate a client-ready Feasibility Pack in as little as 1–2 hours.

Which KPIs can Hysopt compare?

Hysopt compares the metrics that matter most for early HVAC decisions, including CAPEX, OPEX, CO₂ emissions, energy consumption, heat pump capacity, buffer vessel volume and other key asset sizes. Results are presented side by side so design trade-offs are easy to explain and defend.

What is included in the Feasibility Pack?

The Feasibility Pack includes compared HVAC concepts, CAPEX, OPEX and CO₂ comparisons, key equipment sizing, engineering assumptions, identified risks and presentation-ready outputs for client meetings, tender submissions and internal decision making.

Do we need BIM to use Hysopt Feasibility?

No. Hysopt Feasibility is designed for the earliest stages of HVAC design, where BIM models often don't exist yet. You can generate and compare HVAC concepts using templates and minimal project inputs. BIM can be integrated later as the project progresses.

How does Hysopt reduce project risk?

Hysopt validates HVAC concepts before detailed design begins using physics-based modelling, hydraulic validation and dynamic simulation. This helps identify oversizing, hydraulic conflicts, control issues and inefficient system behaviour early, reducing engineering rework, commissioning issues and costly design changes later in the project.
