Efficient spotprice control of ventilation in real estate

Purpose and goal: ** Denna text är maskinöversatt **

The aim of shifting energy consumption from hours with high electricity price (high load) to hours with low price (low load) has been achieved with the help of the developed function. The aim of the project has been to 1. develop the function for control of HVAC with spot price as parameter 2. integrate the function into a property.

3. follow up, and evaluate, savings and performance for the function. These three objective have been fulfilled in the project. Expected results and effects: ** Denna text är maskinöversatt **

The project has tested the function on 2 buildings, these buildings were smaller than the building envisaged in the project´s planning, therefore the saving is less than calculated. The function is estimated to move 2200 kwh per year from the 3 most expensive hours of the day. The result in square meters and year, the function is estimated to save 1 kwh per

square meter and hour. If the function is used by all buildings connected with Sally Rs service, it would correspond to 200,000 kwh per year being moved from the most expensive hour of the day. Approach and implementation: ** Denna text är maskinöversatt ** 1) Implementation and integration of spot price control in Sally Rs Optimization Service

2) Integration of Sally Rs Optimization Service in the Building. 3) Test run and evaluation. 4) Launch of spot price control to Sally Rs existing customers.

Point 1 - 3 has been executed acording to plan.The test run has been carried out on two different buildings. The function is available as a service at Sally R and is therefore available to the existing customers who want to use it.
