This video shows the 0°C degree line (frost line) in motion during a ‘design’ year, which represents a 100 year winter with no snow cover and no vegetative cover, and located in the Ottawa, Ontario, Canada area.
As you can see in the video, the frost line does not move under the slab, so ice lenses cannot form under the slab, and thus the slab does not move.
The time stamp in the video is in days.
The simulation starts on July 1st (day 365, after 1 year of ‘normal’ weather with no snow cover or vegetative cover) and continues to June 30th (day 730).
North America's Largest Passive House - Slab Insulation Design with GEO-Passive LEED ICF Floor - Salus Clementine, Ottawa
With Green Building developments so prominent in the Public Eye, the US and Canadian Construction industry are realizing the growth potential offered by Passive House, Passivhaus, Zero Net Energy and Net Zero Energy Buildings. These types of High Efficiency construction projects require every building element to be optimized, starting with Super Insulated concrete Slabs and Foundations. Legalett have been designing and manufacturing ICF Slab Forms for monolithic concrete slab and foundation construction for 30 years - giving us a significant head start - and Legalett ICF Floor Systems are being chosen for some of North America's most prestigious new High Efficiency Building Projects. For example, this timelapse video below shows the Legalett GEO-Passive product being used in North America's largest Passive House project to date (2016) Salus Clementine in Ottawa, which is also designed to LEED Platinum standards.
Salus Clementine, located in Ottawa, Ontario, is a four-storey, 42-unit affordable housing project for men and women living with severe mental illness and has been described as a beacon project in North America.
Watch ThermalWall PH Super Insulating Wall Panels Installed on a Commercial Passive House Project in Ontario
ThermalWall PH Panels are installed on a 25,000 sqft manufacturing facility in Haliburton ON that is intended to be Passive House Certified. This facility already utilizes Legalett's GEO-Passive super insulated slab and foundation forms.
