It was an exciting day for clients Terry and Frank at our Passive House project in Nailsea this week, as they met with Richard Simon, Director of Solarsense and energy consultant Piers Sadler to hand over the renewables package prior to commissioning and learn how the various elements of the system work, using the latest technology.  Richard Simon, Director of Solarsense, demonstrates the smartphone technology that operates the renewables package for clients Terry & Frank's new Passive House while energy consultant Piers Sadler looks on. The package includes a whole roof integrated 7.3KW PV system, a Mitsubishi air source heat pump with thermal store and the latest TESLA battery – Powerwall 2 - for storage. Once registered with TESLA all the data can be monitored via an App on a smartphone, laptop or tablet. The house, which achieved preliminary air test results of 0.27ACH back in February is almost complete and ready to be signed off as a certified Passivhaus - the first in the wider Bristol area.

We recently joined forces with The Green Register to offer a site visit at our current Passivhaus build on an Urban Infill site in Nailsea, near Bristol. They have put together a short video of the afternoon - click below for a taster of the event and a very chilly Richard and Malcolm talking about our commitment to sustainable building and the benefits of partnering with The Green Register for site visits like these. We joined forces with The Green Register last week to offer a site visit to our current Passive House project in Nailsea, near Bristol. Twenty construction professionals braved the cold to visit the Station Rd project, which isn't yet Passivhaus-certified but has already achieved an outstanding preliminary air test result of 0.27ACH. Attendees had the opportunity to look around the site, ask questions and listen to presentations from Greenheart's Richard Hatfield and Passivhaus consultant Piers Sadler. “Richard and I were really pleased with the event - those attending seemed to find it interesting and useful to visit a Passive House project which is still under construction. This gave everyone the ability to see in “real life” how and why the house was put together” said Greenheart Director Malcolm McMahon. We hope to run many more site visits in partnership with The Green Register in the future - watch this space!  
The preliminary air test was carried out on our Nailsea Passive House project on Friday 9th February, achieving the excellent result of 0.27ACH. The house is due for Passivhaus certification once completed but at the moment we are at first fix stage - air tight and weathertight - hence the preliminary test. The result required for Passive compliance is 0.6 ACH @ 50 Pascals and the figure achieved was 0.27 ACH (lower is better). This is a great result and as ever testament to the hard work and attention to detail shown by our guys on site - well done!  Lots going on at our Passivhaus build in Nailsea currently - underfloor heating going in, MVHR installed in the loft, with boards to hold in extra insulation.
