Replace Excel-based feasibility with simulation-driven analysis

Early-stage HVAC feasibility often relies on spreadsheets that are hard to validate and even harder to compare. By bringing feasibility and concept analysis into a simulation-driven environment, you can explore options faster and base decisions on consistent results.

Analyse early-stage energy performance and demand profiles directly in Hysopt, without relying on spreadsheet-based calculations.
Compare HVAC system concepts and plant approaches side by side before committing to detailed design decisions.
Use KPI visualisation—energy use, CO₂ and cost indicators—to confidently support feasibility discussions and concept choices.

Reuse building simulation and energy data without rework

Early-stage feasibility shouldn’t start from scratch. By reusing existing building simulation outputs and measured energy data, you can avoid manual rework and focus directly on evaluating HVAC system concepts and plant strategies.

Import building simulation outputs and measured energy data directly into Hysopt to avoid manual reformatting or data loss.
Simplify early-stage HVAC modelling by representing building demand with equivalent end units instead of fully detailed secondary systems.
Focus faster on HVAC plant selection and system concepts by starting from reliable demand profiles rather than rebuilding models from scratch.

Reuse existing building simulation and energy data in your feasibility studies.

Compare early-stage HVAC scenarios before committing to design

Before detailed design begins, it’s critical to understand how different HVAC concepts perform under real demand conditions. Comparing scenarios early helps clarify trade-offs and align stakeholders around the right system approach from the start.

Explore and compare multiple HVAC system concepts and plant configurations early to understand their impact on energy performance and feasibility.
Assess trade-offs between efficiency, cost and system complexity at concept level, before detailed sizing or engineering starts.
Use consistent simulation results to align engineers, consultants and stakeholders around early-stage system decisions.

Frequently asked questions

What is HVAC feasibility analysis?

HVAC feasibility analysis evaluates whether different HVAC system concepts can meet a building’s energy demand, performance targets and constraints before detailed design starts. It focuses on comparing system approaches early, rather than sizing individual components.

When should HVAC feasibility be performed in a project?

HVAC feasibility is most valuable in the early project stages, when system concepts and plant strategies are still open for discussion. Making these decisions early helps avoid rework, oversizing and suboptimal system choices later in the design process.

How does this differ from detailed HVAC design and simulation?

Early-stage feasibility focuses on comparing concepts and system approaches using demand profiles and high-level models. Detailed HVAC design and simulation come later and involve full system layouts, component sizing and detailed engineering calculations.

Can I reuse building simulation or energy data for HVAC feasibility?

Yes. Existing building simulation outputs or measured energy data can be reused directly to support HVAC feasibility and concept modelling, avoiding the need to rebuild models or manually reformat data in spreadsheets.

Why replace Excel for HVAC feasibility studies?

Spreadsheet-based feasibility analysis is time-consuming, difficult to validate and hard to scale across scenarios. Simulation-driven workflows provide consistent results, clearer comparisons and better support for early-stage decision-making.
