Parker Lahti

Owner and Founder of ARUS Consulting

With over a decade of experience in building science and energy efficiency advising, 5200+ assessments under his belt, and 30 full home renovations completed under his supervision, Parker founded ARUS to create a new model for residential energy assessment firms. ARUS is committed to the communities we serve and resident education.
