This is the good practice's implementation level. It can be national, regional or local.
About this good practice
One of our stakeholders, Östersundshem has tested controlling heating of buildings based on forecasts. Two similar buidings from the 60ths. One were the system vere adjusted with manual control accondingly to weather forcasts and one with automatic control connected to weather forecasts provided from an external digital service.
The technology calculates how much energy to be supplied to a building, based on very local weather forecasts. In this case, the technology has been used for heating control, but it can also be relevant in use for comfort cooling.
Practical application of forecast control generally use remote-controlled forecast receivers that send and receive data over GPRS or GSM network. The forecast receiver in turn controls the controllers placed in the building and regulate the heatdistribution.
The automatic control connected to weather forecasts gave a energysaving of the buiding of 9 % and the manual a energysaving of 5%.
Strenghts/weaknesses
• Energy savings of 10-20 kWh / m2
• More consistent indoor climate
• Reduced environmental impact

Resources needed
Startup costs; 2000 euro
Evidence of success
Indicators of success linked to the practice:
- More consistent indoor climate
- Reduced energy consumption
Evidence of success.
Results:
-9% Energy savings with automatic controll. (4000-5000 euro savings per alley)
-5% Energy savings with manual control
- More consistent indoor climate
- Reduced energy consumption
Evidence of success.
Results:
-9% Energy savings with automatic controll. (4000-5000 euro savings per alley)
-5% Energy savings with manual control
Potential for learning or transfer
Very good. A energy saving technique that is suitable when other energy efficiency measures have been done.
Both manual and automatic control saves energy but the automatic is more efficient.
