Testimonials
Proven Results in Real Buildings — Savings, Comfort, and Control
"We’ve piloted Fourdeg in schools, offices, and residential buildings — and consistently achieved over 20% in energy savings. But beyond the numbers, building occupants have noticed more stable indoor temperatures, and property managers appreciate the predictability of maintenance work."
— Markku Makkonen, Founder of Fourdeg
Improved Indoor Comfort — with Lower Energy Use
“With smart heating control, we’ve achieved more stable indoor temperatures while using less energy overall.
Our staff has clearly noticed the difference — the conditions feel more consistent and comfortable throughout the premises.”
– Mr. Antti Toivanen, Business Director, Lassila & Tikanoja

The Story Behind
Fourdeg Smart Heating
Fourdeg was founded in 2013 by a group of Finnish innovators driven by one mission: to help cities and buildings reduce heating emissions through smarter energy use.
By combining the Internet of Things (IoT) with AI-powered cloud services, we created a new way to optimize energy efficiency in district-heated buildings.
Our system enhances how entire heating networks operate — enabling intelligent, room-level control, easy-to-install smart thermostats, and seamless integration into both modern and older building stock.
Recognized. Awarded. Patented.
Our smart heating innovation is driving change — and earning recognition across Europe.
Fourdeg’s technology is patented in the EU and has received multiple international awards for energy innovation, climate impact, and digital transformation in the built environment.
In 2018, we were honored as a WWF Climate Solver for our contribution to reducing global carbon emissions through smart heating.
From Pilot Success to
Scaled Impact
After years of development and field validation, Fourdeg has delivered over 70 successful smart heating installations in office, residential, and public buildings between 2018 and 2021 — most of which remain actively in use today.
To accelerate our mission of sustainable district heating, Fourdeg was acquired by MeshWorks Wireless Oy in spring 2022. Together, we’re scaling the solution to reach new cities, networks, and partners across Europe.
