WYRM MEP / Thermal modelling
Heat loss and cooling,
space by space.
Explore the building, inspect its loads, study the sun and open the calculation report from the same thermal model.

Recorded appliance calculation
Recorded calculation with assumed inputs; engineering review required. Fictional room names replace project identifiers. The browser displays saved results and does not run a new simulation.
Site context / visual concept
The model.
In its surroundings.
A Gaussian-splat capture can provide a photographic 3D view of the site. This architectural concept illustrates that setting, with neighbouring buildings, trees and street geometry in view.
This is a context-view concept. The installed solar engine uses explicit shading factors. A site-capture workflow would need verified scale, north and alignment, with relevant obstructions converted into reviewed calculation geometry.
Build the thermal model from the project
Use the building geometry and room boundaries with fabric constructions, glazing, shading, infiltration and ventilation inputs. Add occupancy, equipment gains and operating schedules so the assessment reflects how each space is used. Keep the source and assumptions with the model.
Run the thermal calculation track
Review the model inputs, then run heating and cooling calculations on the appliance. Winter balances include fabric, ground, adjacent spaces and air treatment. The weather-year simulation retains room peak times and the building's coincident cooling duty, so individual room peaks are not mistaken for the central plant load.
Size and select the equipment
Carry room and system duties into equipment sizing. Reference manufacturer performance data at the design conditions, together with dimensions, connections and access requirements. Keep the selected capacity linked to the thermal assessment that established the duty.
Draw and coordinate the design
WYRM draws the sized services into the building layout. Coordinate plant, terminals, distribution routes and other disciplines, then carry the selections into the Revit workflow, specifications and schedules. Changes to the building feed back into the assessment and the affected design work.
Keep the report and its history
Generate heating and cooling reports as PDF, HTML or Excel. Retain the requester, timestamps, job status, errors and completed downloads in Report history. Detailed diagnostics keep the inputs, assumptions, component balances and solver warnings available for engineering review.
Example workflow
From 33 rooms to a calculated load schedule
- Start with
- A three-level model with 32 thermal zones, assumed fabric, room-use inputs and a London design-summer weather file. Kitchen and dining spaces share one zone.
- Work towards
- The recorded example returns 37.471 kW winter heating and 46.889 kW coincident total cooling. Review room duties, assumptions and solver warnings before selecting equipment. Keep the report as the calculation basis for the next design step.
Working with your team
Does the workflow include Passivhaus?
Passivhaus and PHPP form part of the low energy design coverage. The dedicated page explains how fabric, ventilation, demand and project information fit into that workflow.
How are results reviewed?
Review the assessment method, inputs, units and assumptions alongside the result. Your engineer decides how the assessment informs the design and which further checks the project requires.
