How is SMEasure Configured and can it show energy savings associated with domestic hot water?

Hi, my name is Don Johnston and I chair a Business Energy Management Group (see www.seemg.org.uk). I confess to having set up my domestic energy use as a 'small office' in order to access the graphs and other energy management details available to businesses as I have been evaluating SMEasure for our members, particularly one who makes EWT (electronic water treatment) to deal with hard water. The success of his treatment is difficult to measure in energy saved terms and we have been looking at SMEasure as a potential mechanism to achieve this 'independently'. To understand whether it can achieve this I need to fully understand the following:
1. The basic details to set up an account does not include 'U' values or details of the building structure so I presume some average figure is used.
2. Similarly, no information is asked re how much energy is used for domestic hot water as opposed to space heating, so I again to presume that an average value is allocated for the building use. We understand from Russell layberry that the energy usage value determined for domestic hot water is the 'lock' point for the left side of the building energy graph which compares the efficient use of energy to heat the building compared with prevailing outside temperatures (degree day data).
3. If an SMEasure user made savings on energy consumption associated with domestic hot water I have to presume that the building energy graph would not be able to reveal this. The left anchor point of the graph would remain unchanged and any energy reduction obtained with domestic hot water would rather be attributed to energy savings asociated with building heating.
Most of our members have BMS's but SMEasure could be of assistance to our members from smaller businesses. There are 4 other EEMG's in the GOSW area (see 'www.oursouthwest.com').
I should appreciate your comments on these issues. If you prefer to discuss these issues I can be contacted on 02392 556965.
Kind regards, Don Johnston
