Adhoco‘s contribution

to the project


to implement home automation
in
existing

buildings


to control in
integrated

way

-

lights

-

blinds/shades

-

heating


to apply state
-
of
-
the
-
art
wireless

communication to save
costs and time


to implement pre
-
programmed
energy
-
saving algorithms



to ensure
acceptance

by users

The solution:


adaptive home automation

saves 25 to 40% of energy


automation brings comfort
standards of the automobile

into the home


integrated system allows

rich set of features


internet access enables

„home in the pocket“

Automation saves energy (I): Energy consumption


defined in litres for 100 km


reference: standardised drive cycle


test under idealised conditions (tyre
pressure, closed windows, no A/C)


prudent driver



Label:
Energy label (A, B, ...)

idealised user (habits)



Label: z.B.
Minergie, energy label


„sportive“ driving


open windows, low tire pressure,
„forgotten“ roof racks


longer distances


heavier vehicles with more power



per capita consumption higher than
theory


overheated rooms


open windows, unserviced
appliances


larger apartments, second homes


additional appliances (PC, home
electronics, A/C, wellness, ...)


per capita consumption higher than
theory

Automation saves energy (II): true energy consumption

What our system does:


comfort control of lights, blinds, and heating


correction of undesirable user actions by automation
(e.g. shut off „forgotten“ lights)


self
-
adaption to user wishes (learning)

to increase the acceptance of automated appliances


self
-
adaptation to thermal inertia of building,

to optimise start/stop times of heating


weather and occupancy forecast


while unoccupied: energy

saving settings


low internal energy consumption

(0.3
