Before you build a greenhouse, earth-tube system or growing facility, I can tell you how much energy it will need, what size the equipment should be, and which design changes are worth paying for. You get answers from a calibrated simulation, not a rule of thumb.
Hourly heating and cooling demand across a full year, for any climate from the Prairies to the Gulf Coast.
Pipe length, depth, spacing and airflow sized against the real heating and cooling load, with soil temperature modelled.
HVAC loads from lighting and plant transpiration, and CFD airflow to find hot spots and dead zones in the racks.
Envelope, ventilation and conditioning loads for buildings where the climate inside affects the product.
Peak and annual demand, hour by hour, from local weather files.
Heat pumps, boilers, fans and earth tubes sized to the load, not oversized for safety.
Radiance-based light maps across the crop for orientation, glazing, screens and reflectors.
Hundreds of design variants run in Python, so you see which combination pays back fastest.
Thermal screens, covers, set-points and controls compared side by side in kWh and dollars.
Method, assumptions and results written so engineers, growers and funders can all follow them.
You describe the building, location and the decision you need to make. I tell you what is worth modelling.
A fixed scope with deliverables and a timeline, so you know the cost before work starts.
I build the model from your drawings and run the design options, with check-ins at the midpoint.
