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)
