1. Adaptive Building Automation: Saving energy AND increasing comfort with low investments for existing buildings

2. Overview  The HOLISTIC project  Why does automation save energy ?  Some details of the Adhoco solution  Achievable energy savings  Costs

3. HOLISTIC: a “sister project to STACCATO Dundalk (IR) Mödling (AT) Neuchatel (CH) Holistic Optimisation Leading to Integration of Sustainable Technologies In Communities

4. 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 km 2 – 17% or the city area  4’700 inhabitants, 16% of the city population  Present different activities: school, shops, dwellings, private institution Association Ecoparc: développement durable dans l’environnement construit et la gestion d’entreprise Suisse - Neuchâtel

5. 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

6. 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

7. The Adhoco products weather station presence detector temperature / humidity sensor central unit Internet remote control on/off or dimming switch blind controller room temperature controller wireless Internet

8. Wireless communication: Zigbee®  true network  bidirectional  encoded  low energy consumption  low radiation  international standard (IEEE 802.15.4)  open standard

9. Product (1) intelligent central station  centralised intelligence  wireless communication with system components  gives smart commands to all actuators  connected to internet (VPN) for remote monitoring, control, and management  attraktive design (Red Dot Design Award)

10. Product (2) Components occupancy / illumination sensor light (on/off, dimmer) for fixed installation temperature / humidity sensor light (on/off, dimmer) for mobile application Mini-Meteo stationblinds / shades / shutter control underfloor heating control valve control for radiators

11. actuators: small, clever...  conventional installation  existing switches can be reused  no configuration required  no programming required

12. 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

13.  „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

14. 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 (0.3-0.5 W per component)

15. Experimental results (PhD Study)  9 month duration  3 seasons und 3 operation modes  Manual  Automation, no adaptation  Automation, with adaptation  14 office rooms  random operation modes  « Single-blind » Study  23 users  feedback about comfort and satisfaction existing office building,Lausanne

16. Experimental results - Temperature conventional adaptive automation cold rooms less frequently hot rooms less frequently

17. Experimental Resultats - Illumination conventional adaptive automation less glare brighter light

18. Experimental Result: lower energy use adaptive automation is effective

19. cost example central unit (1) Total: 31 components presence/light (7) temp/humdity (4) meteo station (1) light switch (7) blind control (4) valve controls (7) material cost:4000 € installation cost: max 1 man-day

20. Low TOTAL COSTS of ownership 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 costs Attractive margins for  Adhoco (manufacturer)  Installer (Adhoco‘s sales partner)

21. Product status  now commercially available  numerous references  network of distributors being built up  proposal: application also in STACCATO communities
