Meter Readings Project
UPDATE July 2013
After four years of collecting
meter readings from households in Henley I have produced these
two charts showing the comparison for each month of the Average
consumption in each year.
I have also produced a comparison of temperature deviation
from the long term average for the same period.
Obviously there is an increase in heating consumption in cold
weather but there are places where this comparison is not
exactly predictable. Any thoughts?
I hope, by continuing with our survey, we will
soon be able to detect that we are reducing our energy consumption.
UPDATE November 2012
Here are three updated
charts which present the averages so far for Gas Electricity
and temperature variation from mean.
UPDATE June 2012
3 Years of measuring energy consumption in a sample of Henley
We have now been collecting monthly data on energy consumption
from a number of households in Henley for three years.
To present data in a relatively simple form this has been
used to calculate a monthly Henley Average. We
hope in time to be able to identify trends in our consumption
Here are three charts
which present the averages so far for Gas Electricity and
temperature variation from mean.
Clearly our consumption is most affected by the weather, and
it will need further analysis to see if any weather
corrected trend can be detected.
We hope that by merely looking at our monthly readings we
will be more aware of our energy use.
I would like to thank all those who have taken part so far
and I hope you will all continue to send your readings.

UPDATE November 2011
As we are now six months into our third year of recording
meter readings, I thought I would explain what I am doing
All the readings for the first two years are still available
and can be incorporated in any historical statistics we think
will be useful.
As it is difficult to illustrate more than two years of the
averaged readings on one char, and as over time there have
been changes to regular contributors, I started a new spreadsheet
at the beginning of May 2011. I intend to run this for two
years, so we will then have a comparison with the first two
years. From time to time the latest charts will be available
either through the monthly reminder or on the HiT website.

PRESENTATION OF RESULTS 2009/2010
I have produced a curve, (below), comparing our average consumptions
of Electricity and Gas in energy units (kWh) rather than as
a percentage of our maximum demand.
The new curve emphasises how much more energy we use as heat
for our homes and our water compared with energy used in the
form of electricity for all the other purposes.
Since May 2009 we have been collecting, on the first day
of each month, the Electricity and Gas meter readings from
interested Henley and District residents.
Our aim is to measure consumption patterns over the seasons
and over a number of years. We hope we will be able to detect
a reduction in our use of energy and also provide some statistics
which will allow individual families to compare their usage
with the average for all the participants.
We are also plotting the monthly average temperature variation
from normal to give us a measure of weather conditions.
We believe that an immediate benefit has been that many participants
are taking a new interest in their own energy consumption.
A number have obtained Smart Meters so the effect
of their various electrical devices can be measured. A number
of the power companies are even offering free Smart Meters.
As the months pass we will be able to show the changes from
last year. The data from the first 24 Months is shown on the
two charts below. The first shows the seasonal variation and
is plotted as a percentage of the maximum monthly consumption
in December 2009 and the second shows whether the average
monthly temperature was warmer or colder than normal.
Data from the first year of our survey is shown in one colour
and the data from the second year is shown in a slightly brighter
We are looking for more contributors who can respond to a
monthly email and send us your meter readings, which will
be used anonymously. We are particularly interested if you
have fitted any solar or wind generation and are exporting
your surplus energy.
