Idea

Reducing energy consumption and heat loss by using movement detectionin the office.

Nowadays in most offices people spend more time than in their apartments. Working place became a very important place for every employee, and therefore companies spend thousands euros in order to make this place better. But usually people are careless about the resources they are spending: for example, when it is too hot in the room, instead of reducing the temperature in the room, the employee usually just opens the window. The company pays for the heating of the building, the company pays electricity bills, so for a particular worker there is no need to think about reducing its own energy consumption.

Following this logic, the company owners now need to think about the ways to reduce their expenses on heating and consuming of energy. Our team tried to imagine and implemented a particular scenario about reducing energy consumption and thus saving the costs for company owners.

Scenario

For our scenario we used a set of equipment, which includes motion sensor, dimmer, Twilight sensor and thermostat. Firstly, our system will detect the movement in the room using the motion sensor as a trigger. If there are people inside the room - the motion sensor will detect the movement and all the other sensors will start to work. If there's nobody inside - there's no need for running the whole system.

The next step comes when the sensor detects the movements. Usually companies try to build spacious offices, full of light and with big windows from floor to the ceiling. During sunny days, the sunlight easily comes through these windows to the room, increasing the temperature inside. Our light sensor will detect if the day is sunny, and then the control is going to the thermostat. If the temperature inthe room starts to increase, the thermostat will detect it and at some threshold value the heating of the room will be stopped.

Usually in most of the companies working day is scheduled, and it is easy to predict the end of working hours. Therefore, the other part of our system will control whether the employee turned off the lights in the office or not. After 15 minutes of the end of working day the motion sensor will check if the room is empty or not. If it is empty and the lights are still turned on - then the system will send a notification to the e-mail address of the worker, informing that the lights are still on, and inviting to come back and turn off the lights. If after another 15 minutes the lights are still on, that means that we are dealing with an irresponsible employee and there’s a need to change people’s behaviour. That means the system will automatically turn off the lights via the usage of dimmer, and the employee will be penalised with a certain amount of money cut off from the salary.

Calculation of Savings

Electrical equipment:

Normal Scenario

9 working hours per day

5 days per week

46 weeks (4 weeks of vacations + 2 weeks for business trips)

1 PC, 2 Flat screens, 1 printer and lights

Price of 1 kWh = 0.05 euros.

Automation Scenario

7 working hours per day

5 days per week

46 weeks (4 weeks of vacations + 2 weeks for business trips)

1 PC, 2 Flat screens, 1 printer and lights

Price of 1 kWh = 0.05 euros.

Climate control:

Normal Scenario

12 working hours per day

5 days per week

52 weeks

18 m2, electric heating, comfort temperature 20-22C.

Default CO2 emission for Finland = 0.225 kgCO2/kWh

Automation Scenario:

9 working hours per day

5 days per week

46 weeks (4 weeks of vacations + 2 weeks for business trips)

18 m2, electric heating, comfort temperature 20-22C.

Default CO2 emission for Finland = 0.225 kgCO2/kWh

Savings of CO2 emission per year per employee - 141.85 kgCO2

Savings of costs per year per employee - 33.59 euros.
