I am searching the web for a couple of nights now, and still i cannot find a solid arguement to choose a system.
A little bit about myself, since this is my first post.
My name is Friso, 27 years old, running a little IT company in the netherlands. (yes, experience in programming, electrics and installation services)
Since July 2012 i bought a nice villa wich is build in industrial style, what does this mean for Domotica? Well... All electrical systems are not inside the walls but visible on the walls, this also includes all lightswitches and wall outlets.
In the near future i will start with removing all current electrical wires. and lightning. This house will be complete greenfield... Here is also where my issue starts....
I need to redo all wiring, wich makes it easy to do it right in the first place.... but how do i choose a system that fits greenfield? Current suppliers and manufacturers are mostly focused on renocation and current light switches...
The less i need to drill in that concrete house the better.... the less copper i need... the better.... the cheaper....... I need to make a business case VS a conventional system... to convince my girlfriend

Now how do i decide what system i need to purchase?
Current leading systems are:
KNX
Z-wave
Zigbee
First KNX: I still need to drill lightning switches and preferably push the data cable in it aswell... Next to that KNX is expensive but market-leading.
Second Zigbee: I like the idea and methods, but they are not compatible with most cases.
Last (and maybe best) Z-Wave: I love that Vera controller, but i cannot find ANYTHING about a greenfield situation, most hardware is focussed on renovation.
Wishlist:
Fully wirless lightning controll (offcourse i will have to get 230v to the bulbs... but the switches need to be wireless.)
Door and windows sensors (wireless preferred)
Power monitoring: Since it is greenfield and i also need to replace the Main power switches and fuses, i might want to monitor the powerconsumption on Fuse level. It would also be nice if i could disable wall outlets. Its also possible to have each wall outlet conneting directly with a fuse...
Is there anyone that is experienced with a greenfield project? whats a list that i need? How do i switch those lightbulbs (transmitter on the wall and receiver near the bulb??? or in the fusebox??)
Is there one single brand that covers all my needs? Or do i need to mix?
Thanks in Advance...
Friso
