Pick a use, a footprint and a city. We compute clear height, membrane area, design snow load, the internal pressure needed to carry it, plant sizing — and what the insulated ALDO envelope saves you every year against a conventional R-3.2 dome.

Preliminary sizing from published NBC 2020 climatic data for the selected city and ALDO's Edmonton lifecycle model (107,000 sf, 250 × 428 ft, natural gas $0.06/m³). Every project is confirmed by site-specific structural calculation, energy modelling and stamped drawings.
