Psychrometric Studio
Moist-air analysis for real buildings
- Seventeen equipment types, solved stage by stage
- ASHRAE 55-2023 comfort, evaluated live as you work
- A full year of EPW weather counted against your design
Exploring ways to improve how we design and analyze the built environment
Pease Studio is a collection of browser-based tools for building performance. Everything is a beta version today as I continue to refine with feedback and discovery.
Tools
All toolsZEEL
Zoned energy estimation for laboratory buildings
- Twenty-one lab zone types, entered as areas
- Estimated EUI, carbon and operating cost from the programme
- Five climate zones and seven conservation measures
Heat Balance Studio
Envelope heat balance for early-stage design
- Eighteen building types from the PNNL prototype models
- Five envelope surfaces, by U-value or R-value
- Gains and 24-hour schedules per type, all of them editable
Thermal Network Studio
Could this neighbourhood share its heat?
- Draw any US neighbourhood on a real map
- Hourly heating and cooling for every building, calibrated to national stock
- Bore fields, heat pumps, towers, rivers and waste heat on one loop

All papersPease, P., J. Chhabra, A. Padwal, and Z. Zolfaghari. 2023. Passive or active, mapping the highest impact HVAC design interventions across the USA. 2023 ASHRAE Winter Conference. doi.org/10.63044/w23pea71
Which HVAC change actually cuts the most carbon depends on where the building is. This maps the highest-impact intervention for every climate zone in the USA, so the answer stops being a guess.
Pease, P., A. Padwal, and M. Tahmasebi. 2023. Scaling decarbonization with early-stage energy modeling. ASHRAE Transactions 129:708–714. doi.org/10.63044/s23pea80
The cheapest carbon reductions are decided before anyone opens a modelling tool. This argues for moving energy analysis to the earliest design stage, where a decision still costs nothing to change.
About
MoreI lead building performance simulation for Buro Happold's US offices, and I've spent fourteen years on whole-building energy modelling and the workflows that make simulation scalable. These tools are the parts of that work that were worth building properly.
