If you own a very nice sports car there is a dilemma between maintain and enhance that will one day confront you.
It is different for an energy manager.
Maintain / Enhance - No Management Dilemma

10 Smart-Meter Answers - why gas before electricity ?
Hopefully this short post will spark or fire up some debate.
Assume you have 100 buildings and 100 smart-meters and each building uses gas for heating & hot water and electricity for cooling and lights, socket loads etc. So each building for primary utility supply requires two smart-meters without considering water.
So should you install smart gas meters then electricity or vice-verse ? I know what I think - read on..

Best or most improved - Energy Attitudes!
'Does it makes sense to buy a building with good benchmark performance ?'
I asked my colleague this and he didn't know the answer (he probably realised it was a trick question ) - Have you ever REALLY thought about it ?
Obviously better buildings are simply better - all other things being equal. Other things are never equal!
Benchmark studies compare buildings against their peers. So energy cost of a square foot of office space seems a useful comparison in a particular region. And it is, but different buildings are managed better or worse by different owners. The benchmark tells you nothing about how to improve !
Single performance benchmark can seriously muddy the water.

NodeJSRocks - Walking the Walk
A couple of months back I said a colleague and I were messing around at a Google DevFest with some ideas for the Raspberry Pi and Arduino. We were just showing the truly disruptive potential of a zero cost great O/S on high quality low cost hardware by reading some USB themometers.
It's all very exciting to talk the talk - but sometime companies need to walk the walk. So we are please to announce that we are now sponsoring an Open Source Experiment on github.
You can read about it in it's very early form here... (A blog post by my colleague Andreas who authors the brilliant NodeJSRocks blog )
http://nodejsrocks.blogspot.ch/2013/01/measure-temperatures-with-usb.html
Actually if you have anything to do with NodeJs more generally you should subscribe to his blog.
So if you want to contribute time, ideas, code or simply have a play at getting your Raspberry Pi to graph the temperature of the coffee on your desk (or more useful applications) here is where you can.

Obviously, more is to come. I have been involved in specifying an entire BMS / BCS many years ago that met with some commercial success, and I think it is time we disrupted a few very slow very died-in-the-wool markets. One thing is clear, the old days of closed protocol lock-in are still here for many energy managers and HVAC installation companies.
The intellectual input to produce an open source, openly configurable control, open-communicating system with great self-diagnostics exists. And if it were produced it would shake some corporate assumptions pretty dramatically.
So let's have some fun!
Oh - and anyone that thinks Honeywell and Siemens don't have a problem from the upstart that is Raspberry Pi had better watch out !...
PS I know about BacNet etc - but is has failed to deliver what it could on so many levels because it is built on the idea of "first risk nothing" approach. The world has to change and that is going to take some risks. The least of which is upsetting some apple carts - so whoops !

Who put the Fun in Fundamental ?
Fundamental is a great word - Why ?
From Wikipedia
Noun - fundament (plural fundaments)
Human activity is messing with the planet at a fundamental level whether politicians like it or not - Sadly it seems many do!
And politicians need to get up off their lazy fundaments (to use the word exactly) and do something about climate change.
So why am I harping on about fundamental today?
Fundamentals are also deep rooted beliefs or grounding principals. All activity involve energy - everything we do. Since life is a process, energy use is unavoidable - it is not an option.
The word Fundament also seems to have a fundamental frequency - Does this prove politicians like to talk out of their fundaments too - Note the Spring peak - "We'are building on new beginnings "!

Noun - fundament (plural fundaments)
- Foundation.
- The bottom; the buttocks or anus.
- The underlying basis or principle for a theoretical or mathematical system.

- Humans require air to breathe, food to eat and stable, unflooded, but irrigated ground (fundament) to build their lives upon, and weather conditions to make that tenable
- Politicians have their heads up their collective fundaments on climate change.
