TALK DATA

understanding your real energy world

through

sensors, meters, data, projects and interaction

because

smarter homes need smarter people

boteproject HOME EXPLAINED PROJECTS MORE

Presentation agenda

• The principles of boteproject and link to smart systems

• Demonstration of some of my favourite sensing devices

• Some graphs to test your smartness and requirement to vote (6 times)

• A smart simulation activity with group participation (once)

• What next and an invitation

• Questions

there are two slides with cats

boteproject 3 elements

• sensors and meters that are cheap to buy and easy to configure

• used to carry out investigations into the efficiency of heating, machines, lights etc

• In order to allow meaningful sharing and benchmarking across a smarter community

The power of the machine

Calibrate the audience for the simulation

• Perception of temperature is not necessarily so smart

• Wide variations in individual comfort ‘requirements’

• Affected by other factors not just ambient temperature

VOTE 5:

A - 25 or more

B - 23 C - 21 D - 19 or less

VOTE 6: A - too hot B - comfortable C - too cold

Smart controllers a simulation - the basic rules• Andrew’s home office (box room) temperature should be just right for energy

strategising when he gets home from the IoT meet (see graph of productivity)

• Yellow green and red balls represent heat that is supplied by the boiler (bag), passed through the pipework and may, or may not, be deposited into the home office (box) by the radiator to raise the temperature by one degree

• No length of pipework can contain more than one unit of heat and must pass the heat on through the system upon receipt

• The boiler may not put heat back in the bag, the pipes can only pass heat clockwise in the ‘circuit’

• Blue balls added to the home office represent a loss of heat by one degree each and no heat (or cold) cannot be removed from the home office (box) at anytime (exception for team A….). Remember, that the more heat there is in a room (compared to its surroundings) the more will be lost….

• The simulation will run until Andrew gets home (approx 4 minutes) with an interval or two to check progress.

Smart controllers a simulation - rules getting complicated• Team A - Smart controller without zoning or room sensing.

• Smart Controller must instruct boiler to produce each heat ball, the pipework must let heat flow and the radiator must put one in every two ‘heat balls’ passed by the pipework into the box room, letting the alternate ball pass round the system. The radiator may not open the box room until the end of the simulation, at which time any number of heat balls may be removed (window open principle).

• Team B - Smarter controller with zoning and room sensing.

• Smart controller must instruct boiler to produce each heat ball, the pipework must let heat flow but the radiator can choose whether to put the heat in the box room or let it flow round the pipework. The radiator may not remove any heat or cold at any time.

• Teams C and D - Future tech controllers

• These systems are so very smart (7G Nest….) that no rules apply to them apart from leaving heat and cold in the box room.

The outcome - a control expert’s prediction

team A : (not so smart)

10+10=20 degrees

temperature achieved

energy used

10+5=15 kWh

team B : (smarter)

teams C and D : (too smart?)

8+10=18 degrees 8+5=13 kWh

10+10=20 degrees 10+4=14 kWh

Is this the vision?

the boteproject ambition is better informed choices and operating practices by smarter energy users

not devices and companies that do all the thinking for us
