Energy consumption for heating and cooling of buildings is in essence a function of required system temperature and thermal conservation. Synenergi has developed a solution addressing both areas through a combination of unique design, latest technologies and AI. The concept can be applied in both new and existing buildings. Energy savings for heating are more than 80% vs. traditional solutions. ROI is normally between 3-6 years, depending on the comparable/previous system used.
Solution
Hot Air vs Solid Heat
High Temperature
Sourcing high-temperature heat, e.g., from:
-
Gas boilers
-
District Heating
-
Electrical Boilers
Hot Air
Distributing heat through aero tempers, i.e., by heating up the air in the building
Heat easily lost
Heat flows out with the air, e.g., when doors are opened in a logistics centre, thereby requiring further input of henergy
No cooling
A separate cooling system has to be implemented - cooling down the air not cost effective
Low Temperature
Sourcing low-temperature heat, e.g., from:
-
Air-to-water heat pumps
-
Water-to-water heat pumps – sewers, mine workings, data centres, solar thermal
Warm Building
Distributing heat through the floor, i.e., by warming up the slab under the building
Heat stays inside
The slab becomes a thermal battery keeping the heat indoors. Less additional energy required.
Comfort cooling
Cooling solution is fully integrated in the system – reversing the heat pump to cool down the slab

Starting Point
Energy consumption for heating and cooling of buildings is in essence a function of required system temperature, i.e. the temperature of the conduit of heating and cooling into the building, and the thermal conservation in the building itself. One challenge is to reduce the flow temperature as much as possible. The other is to conserve as much heat (or cooling) inside the building for as long as possible with no negative impact on air quality.
Reducing System Temperature
The aim is to reduce the flow temperature into a building as much as possible while still maintaining a high level of indoor comfort. Traditional systems operate with high temperatures which limits the choice of heat source and reduces energy efficiency. Most buildings in Europe are heated by gas boilers to meet the requirements for indoor comfort. Heat pumps are less efficient at high temperatures and therefore not a viable option.
The question is how to reduce the required system temperature. Expanding the size of the radiators is one option. Increasing the flow rate is another. Synenergi combines the two. By installing a very dense self-regulated underfloor heating system and significantly increasing the flow rate we can heat buildings with a flow temperature of <26̊ C. This in turn enables us to design bespoke heat pumps with a COP of 5 or higher, thereby significantly reducing energy consumption and costs. It will also be possible to use other low or no carbon heat sources e.g., geothermal, urban waste heat, solar thermal, low temperature district heating, etc.
Increasing Thermal Conservation
The indoor heat is a valuable resource. You want to keep it there for as long as possible while still preserving air quality. The obvious solution is to secure a high degree of insulation in the building. Synenergi takes it several steps further
Using the floor as a thermal battery. Heating the building itself, not only the air, makes it possible to preserve indoor heat much longer
Ability to re-distribute heat within the building
Securing real-time synchronisation of ventilation, thermal storage in the floor, and indoor air quality
Implementing AI solutions to optimise energy input vs. output
