If you want to do an energiesprong-type panelized deep energy retrofit to make your home energy efficient and net-zero ready, you need to get accurate measurements of the outside of the building.
Photogrammetry - using pictures of a building to "model" its dimensions - is one way to do this.
3D Software Developer and friend of Retrofit Canada, Logan Gilmour, is developing a technique for photogrammetry that uses drones.
Retrofit Canada's partner, Butterwick, is working with Logan to complete three panelized deep energy retrofits of single family homes in 2021.
