Holistic Optimisation Leading to Integration of Sustainable Technologies In Communities
Specific objectives in Neuchâtel (CH)
23% reduction of the consumption of non-renewable energy (saving of 22 GWh per year)
Increase generation of renewable electricity (increase share to 87% of total, from 60%)
The area 5 km2 – 17% or the city area 4’700 inhabitants, 16% of the city
population Present different activities: school,
shops, dwellings, private institution

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“
plug-n-play installation decreases total cost of ownership

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, ...)
defined in MJ/m2 or kWh/m2 a reference:
- standardised use- standardised area- standardisied coefficients
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 heatingcorrection 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 settingslow internal energy consumption
(0.3-0.5 W per component)

Low price for end user moderate component prices multiple use of gathered
information little or no planning necessary simple installation negative operation costs
(energy savings) no or little service costs low investment – low interest
