The Hugh Aston Building boasts a variety of renewable energy technologies. These include ground source heat pumps (GSHP) to provide heating, solar thermal panels to generate hot water from the sun and photovoltaic (PV) panels to generate electricity from the sun. The data for the energy generated from these technologies is incorporated into the smartspaces results

How does the input of the PV's influence Hugh Aston's performance results? The GSHP's were part of the original building so will have helped establish the dataset against which performance is now being assessed. The PV's are fairly new though, so presumably will only have made a relatively recent contribution to that dataset? Does daily input from the PV's offset Hugh Aston's electrical consumption readings?

Yes thats right the electricity from the photovoltaic panels is added into the calculations for Hugh Aston so will ofset consumption slightly

The PV systems provide electricity to the Hugh Aston directly I believe. As such they offset some consumption from the grid and less goes through the meter. Unfortunately its not a huge impact relative to the consumption of the whole building.

There are some display boards in the reception areas of Hugh Aston which show how much electricity is being generated and how much has been generated since the panels were installed

Here's a picture of one of the display boards which shows the amount of electricity produced by the panels. Hugh Aston, Edith Murphy and Gateway all have similar display boards

Great to see PV in use and being monitored. I take it we never get anywhere near exporting any electricity, so the effect is simply to offset consumption?
I am interested in whether any more detailed logging being is undertaken, to understand the seasonal variation in generation etc.?

That's right, the electricity use in Hugh Aston is substantial enough to use up all the electricity that is generated from the PV panels.
There isn't any further detailed logging taking place although that might make a nice project for someone.

All the PV systems on campus are being connected to our meter monitoring system, the same system that provides the data for Smartspaces. This data should start to be avaiable early next week. I am happy to make it available to anyone in IESD who would appreciate it. We wlll be using it to monitor the systems performance.

Excellent news I'd be interested to have access to the data. I feel a collaborative paper coming on - the performance of PV in University buildings...

Yesterday (9th of March 2014) was very sunny so had loads of generation from the PV. As it was a Sunday there wasn't much consumption so looking at the detailed page for Hugh Aston shows the effect of the PV quite clearly. We should see this more and more as the days get longer and brighter.

Yes - that looks quite distinctive At its peak it seems to generating about 10kWh / half hour - is 20kWp somewhere near its max rating?
#13 By: dmu smartspaces team, March 11th, 2014 09:39
Yep that's right. The system in Hugh Aston is split into two parts as its on two different parts of the roof. So each part is about 20kWp adding up to around 45kWp for both parts. There is a minor fault on one part which is in the process of being fixed so the output is right at 20kWp for one part of the Hugh Aston installation

Great to see it working and the data adding up.
