Planning Permission Granted for New Passivhaus Archive

We have been advising Carmarthen County Council on their proposed new Passivhaus Archive in Carmarthen.  

The design is for a new radical low energy archive with minimal plant required to maintain the exacting environmental conditions required for document storage.  

The aim is for this to become the second passivhaus archive in the UK.  We have been working with Elemental Solutions and Alan Clarke to implement the lesons learned from the first Passivhaus archive in Hereford.

Full planning permission was granted in November 2017 and we understand that the project is currently out for tender.  We expect to be retained for Pasivhaus advice during detailed design and construction.

Passivhaus - Is it worth it?

Piers's presentation to a sold out Green Register Bite Size event on 24th November at which he helped Greenheat Sustainable Construction to answer the question - Passivhaus - Is it worth it?  The event was well attended by a range of building professionals who were able to hear from Rich Hatfield of Greenheart how they are using lessons learned from building to the Passivhaus standard in a range of low energy buildings.  Piers's presentation covered costs and benefits and showed how over a 20-30 year period, properly designed Passivhaus buildings will almost always be better value than typical buildings built to current Building Regulations.  He also explained how best to achieve the Passivhaus standard through careful planning, design and construction.

Three rules to make Passivhaus much easier

My July blog for the Green Register explains how to make it much easier (and cheaper) to build a Passivhaus.  These rules aim to guide designers and clients on key features from the outset.  If you don't take note of these riules you probably won't end up with a Passivhaus and your house will be much less energy efficient than you probably hoped.
