WARM new EnerPHit Office opening

  We have just received certification for retrofitting our Office to the Passivhaus EnerPHit standard.    40% of EU carbon emissions come from heating or cooling buildings, and of course, we think that most people wanting to cut this significantly are working under the Passivhaus banner.  We thought the Green Party might agree. Therefore, we are delighted to welcome Molly, our Green MEP, to Plymouth and we have invited her to unveil our EnerPHit plaque marking the first Passivhaus retrofit in Plymouth. Below are some pictures of the...

MVHR: Emoncms.org open source logging – brilliant!

Just got the MVHR up and running before the cold weather hit.  Good job as I was starting to get really irritated with venting via open windows – I seem to get all the draughts to give others in the office the fresh air Anyway, now its been running for a week or two, I decided to get the open source emocms.org monitoring kit we asked John Canton to make up for us in our old office.  Plugged it all in and it worked!  Logging temps, humiditys , powers straight to the website.  Some pulses ( water, gas) too once we get the reed relays...

Week 18: Wrapping Up with Insulation

Week 18: Wrapping Up with Insulation

This post was begun by Emma, enhanced by Liam and beefed up by Sally. The external insulation blocks have gone up really smoothly and the building is almost all covered now. At floor height an XPS (extruded polystyrene) block is used. A key piece of the whole build is yet to be put in: the MVHR (Mechanical Ventilation and Heat Recovery unit). This has been ordered and holes have been made in the wall to accommodate the intake and exhaust ducts. Preparing to move in Inside, the decoration is coming along and a usable office space is taking...

Week 17: A Lick of Paint and Lots of Insulation

Week 17: A Lick of Paint and Lots of Insulation

Insulation is something we talk about a lot in relation to Passivhaus and EnerPHit – it’s a really key aspect to achieving the very low heating demand targets called for by the standards. At Admiral’s Hard our wall insulation is a type of expanded polystyrene (EPS) block that has been treated with graphite in order to improve its insulating properties.  This week the builders have been applying the blocks to the walls using a “muck”, in a way similar to putting up drywall using the dot-and-dab technique. It’s critical to the performance of...

Week 15: Finishing internal works

This week most of the effort has been in finishing off the internal works. Downstairs, floor insulation is going down in the hallway –it’s comprised of two layers of rigid foam insulation (80mm and 25mm).  Extra work was made this week when the decision was taken to open up under the stairs and remove the studwork – it turned out that one area was riddled with woodworm and so that had to be removed and the balustrade replaced. The 80mm layer going in. In the shop Eventually the shop floor will also have a layer of insulation. It seems that...

Week 14: Good news! A great air test result

On Tuesday night Alex ran another fan test, after he and Robbie had been spending the previous days finishing off the last airtightness details – well, fingers were firmly crossed that all the last leaks had been found. And…we’ve done it….a depressurisation result of 0.67 ach at 50Pa! A similar result of 0.69 for pressurisation adds confidence to the construction. What is really interesting is that this last test is significantly better than the previous ones because we opened up an old sealed up door between the office and shop, so that all...

Week 13: Finishing off windows and airtightness

Spirits are high following the encouragement of Friday’s air test results and with the help of the summer sunshine flooding into the building. “It was brilliant, really encouraging to get those results” says Alex. Now the team can start finalising last details of airtightness and finishing off the windows. At this stage, work is concentrating on finishing all the small bits and pieces before moving on to the external insulation – checking for airtightness, finishing off window reveals and boxing, patching up render and finishing plastering....

Week 12: A Lot to Cheer About!

Posted by on Jun 5, 2013 in Warm EnerPHit office | Comments Off

Here’s some great news: we managed a depressurisation air tightness of 0.89 air changes per hour late in the afternoon on Friday! Most of the day had been spent trying to make some remaining aspects of the fabric as airtight as we possibly could.  These efforts focussed primarily on the windows, where we used an airtightness tape specially designed for sealing around windows, and combined this with an airtight adhesive where we wanted to guarantee a good bond to the irregular surface of the render. Once the fan was in place in the doorway, we...
