Our Story

Dartmouth Residential Energy Consulting

Dartmouth Residential Energy Consulting was founded in early 2017 by Chris Larkum, after he recognized a lack of residential energy valuation optimization services. Chris is driven to help builders promote the full value of their product and to help home owners maximize the full value of one of the largest investments they will make in their lifetime.

Chris is motivated by the cost effective solutions to building health and durability that are not commonly understood or current industry best practices.
