-For the heating and power regulation by default heating will lower from 20 to 18 degrees at 19:00 and power will be turned off for all other devices (computers, lighting, etc.) and turned on at 7:00 again. If there are still employees left in the building, a motion sensor will ensure that power and heating remains on until they leave. This is checked via a motion sensor that evaluates employee presence every half-hour. Over the weekend and holidays the same policies as in the nights are applied.+For the heating and power regulation by default heating will lower from 20 to 18 degrees (15 if nobody is present) at 19:00 and power will be turned off for all other devices (computers, lighting, etc.) and turned on at 7:00 again. If there are still employees left in the building, a motion sensor will ensure that power and heating remains on until they leave. This is checked via a motion sensor that evaluates employee presence every half-hour. Over the weekend and holidays the same policies as in the nights are applied.

 +==== Estimated savings ==== 
 +=== Electricity ===  
 +Per employee, we assume the following electricity consumptions: 
 +  * 55 W light  
 +  * 14 W screen  
 +  * 85 W computer 
 + 
 +Total: 154 W,  Per 12h: 1824 Wh possibly saved nighttime per employee 
 + 
 +In price: 0.167 euros per employee per day (Finland EUR 0.0915 per kWh) 
 +In CO2:  0.4112 kgCO2 per day (Finland, 0.2254 kgCO2 per kWh) 
 + 
 +Yearly 60.955 euros, 150.088 kgCO2 per year per employee  
 + 
 +=== Heating ===  
 +Using setback during nights for thermostats savings can be up to 10~15% (D. Quentzel, ASHRAE J), and with using certain classifiers of temperature and comfort reductions up to 20% could be found (Hamdi M., IEEE).  
 + 
 +Using the reference figures of 1.23 euros in price per square foot per year (National Grid), the mean of 890 square feet usage per employee (US EIA), gives the of total cost of 1094.7 euros per employee per year without savings. 
 + 
 +Possible savings should therefore be in the range of 109 to 219 euros (10~20%) per year per employee. 
 + 
 +=== Total savings === 
 +170 to 280 euros saved per year per employee with our solution

-Should copy-paste text here from slides and report too?+Some of the main features of this technology are:
  
 +  * This technology Uses the 868 MHz, 902  MHz and 928 MHz frequency bands (worldwide)
 +  * Telegrams are 1 ms in duration and transmitted at a rate of 125 kbps
 +  * Telegram is repeated twice in the space of 40 ms (eliminate tx errors)
 +  * Data packets are transmitted at random interval (small collisions)
 +  * Range is about 300 m in the free field and up to 30 m inside buildings
 +  * Unique 32-bit identification number (overlap with other wireless switches)
 +  * Enhanced data security features
 +  * RF energy is only transmitted for the 1's of the binary data
 +  * No wires or batteries
