Early HVAC decisions are often made with limited data and little time.
Teams compare concepts in spreadsheets, apply broad sizing assumptions and rebuild each option manually. This makes alternatives slow to assess and difficult to defend.
Hysopt Feasibility brings early-stage analysis into one physics-based HVAC hydronic design software workflow.
Replace disconnected feasibility spreadsheets
Spreadsheets are flexible, but every new concept creates more formulas, files and manual checks.
Hysopt Feasibility allows teams to generate system variants from proven templates using one controlled set of project inputs.
Why it matters: More time comparing concepts, less time rebuilding calculations.

Compare more HVAC concepts faster
The first workable solution is not always the best one.
Teams can quickly test alternatives such as:
- heat pump systems
- hybrid concepts
- different temperature regimes
- peak-load strategies
- alternative plant configurations
Why it matters: Better options remain open before the project becomes difficult to change.

Keep every comparison consistent
A concept comparison only works when each option uses the same:
- building demand
- operating profile
- energy prices
- carbon factors
- project constraints
- performance targets
Why it matters: Results reflect real design differences rather than inconsistent assumptions.
Add hydraulic insight early
Feasibility is not detailed design, but early hydraulic decisions still matter.
Hysopt Feasibility helps teams test system structures, temperature differences, production capacities and other decisions that affect later hydraulic sizing.
Why it matters: Weak concepts are exposed before detailed engineering begins.
Compare CAPEX, OPEX and CO₂ together
Initial cost is only one part of a strong HVAC concept.
Hysopt Feasibility compares:
- CAPEX
- OPEX
- energy use
- CO₂ emissions
- key equipment sizes
- comfort and performance indicators
Why it matters: Clients can see the real trade-offs behind each recommendation.

Test the decisions that shape the project
Early choices can lock in cost and performance for years.
Teams can assess factors such as:
- heat pump capacity
- buffer vessel sizing
- design ΔT
- grid limitations
- control strategies
- operating hours
Why it matters: Major sizing decisions are challenged before equipment is specified.
Support retrofit and decarbonisation studies
Retrofit projects often involve several possible routes with different technical and financial consequences.
Hysopt Feasibility helps teams compare electrification, hybrid and phased improvement scenarios using consistent evidence.
Why it matters: Decarbonisation plans become clearer, more realistic and easier to defend.

Continue into detailed design
A feasibility model should not disappear after concept approval.
The selected option can continue into detailed hydronic design, dynamic simulation, component selection and commissioning preparation through the wider Hysopt workflow.
Why it matters: Teams avoid rebuilding the project and introducing new assumptions.
What teams should expect from feasibility software
Effective HVAC feasibility software should help teams:
- create credible concepts quickly
- replace repetitive spreadsheet work
- compare alternatives consistently
- assess CAPEX, OPEX and CO₂
- test key sizing decisions
- identify risks early
- communicate recommendations clearly
- continue into detailed design
The goal is not simply a faster feasibility study.
It is a stronger decision before detailed engineering begins.
Turn early assumptions into engineering evidence
Early HVAC concepts often rely on broad estimates and disconnected calculations.
Hysopt Feasibility helps engineering and installation teams generate variants, test major decisions and compare performance through one physics-based hydronic digital twin.
That means faster studies, clearer trade-offs and fewer weak assumptions carried into design and commissioning.
