Siim Täkker: real estate sector that can do the most in transition to climate neutrality

Siim Täkker CEO R8 Technologies

Siim Täkker graduated from Tallinn University of Technology in 2017 with a degree in integrated heating and ventilation engineering. He has been an international student at Aalto University in Finland and Electro-Communications University in Japan. Siim is the founder and CEO of R8 Technologies.

R8 Technologies goal is to efficiently use data related to buildings and to manage technical systems as economically as possible with the help of artificial intelligence.

What is the most important thing about indoor climate, something that everyone should know and observe at home and work?

It is the room comfortable and how economically has the required comfort been achieved. Everyone can contribute towards reducing energy consumption and thereby also to curbing global warming. The easiest way to improve thermal comfort is with clothing. For example, in cold weather in winter, it is perfectly normal to wear a sweater instead of a T-shirt indoors. It is advisable to check the air quality with local sensors and adjust the ventilation accordingly. CO2 levels are usually measured, and this should be below 1000ppm. If it is too hot or too cool indoors in the winter when wearing a sweater and the CO2 level tends to go over 1000ppm, something needs to be done about the heating and ventilation systems in the building.

What are the biggest challenges in this field in the next 5-10 years?

As the real estate sector is responsible for around 40% of CO2 emissions, major steps are undoubtedly needed to move closer to climate neutrality. I believe that electrification, energy storage and environmentally friendly materials will be the key words for near-zero energy buildings and buildings with a positive energy balance in the next decade.

How has digital revolution changed this field?

Digitization and the Internet of Things have created an opportunity to make effective use of a wide range of data sets and to measure what has not been possible to measure till now.

Real-time data linking and intelligent algorithms already control the building’s technical systems and the processes involved in building, maintaining and managing them. The main objective is to reduce construction and maintenance costs, improve quality and make data-based decisions.

One myth that I have come across while working in this field?

There are people who believe that when it is cold outside, the radiators must be red hot. But in well insulated buildings this might not necessarily be true because the desired room temperature has been achieved and the radiator does not need to keep heating the room.
