In the past, plywood forms have had a cost advantage over insulated concrete forms as plywood provided no insulation value.
However in the 21st century, with higher energy costs, increasing global temperatures and CO2 emissions, the media and public became concerned with climate change. By 2015 the City of Vancouver changed the building code, requiring all foundations to have an effective thermal performance of R22. This meant that if a contractor formed his foundation with plywood, he must now build an insulated 2x6 stud wall on the inside of his foundation to achieve the required thermal performance.
