Data driven - and sustainable - building operations. Harald belongs to the certain strand of people who think the intersection between information technology and buildings is the most exciting place to be. He heads the ambitious Smart Campus Project at NMBU at Ås, which not only includes new state-of-the-art university buildings but also a full range of older buildings – each one being equipped with sensors and operated through advanced data analysis and algorithms to optimize space use, indoor climate, energy consumption and facility management on campus. He is the perfect speaker at Retrofit Bonanza!
