Paul Mallion will be contributing to SPAB’s (Society for the Protection of Ancient Buildings) ‘Old House Eco’ courses in London on 22 June and in Bristol on 16 November. Paul will be presenting a case study of a Victorian terraced house.
Conker is delighted to announce that Tyland Farmhouse in Sandling, Maidstone was runner up in this years RICS Regional Awards in the ‘Building Conservation’ category for the South East, beaten to the Award by Windsor Castle!
Rescuing the dilapidated building was quite a challenge, Kent Wildlife Trust are delighted with the final building and pleased that their hard work has been recognised, along with Conker and the main contractor, S & T Fullers Ltd.

Recently published, Old House Eco Handbook is a practical guide to retrofitting for energy efficiency and sustainability and a companion volume to Old House Handbook.
Conker Conservation contributed to the section on sustainable insulation.

Planning consent has been obtained to refurbish a farm classroom building.
The refurbishment will provide a low energy, sustainable classroom which will enhance the rural science learning environment for pupils and staff alike. The design embodies a number of low energy strategies; shading has been incorporated to reduce solar gain in summer, whilst still allowing users to benefit from it in winter. High levels of thermal insulation and air tightness will ensure very low heat losses in winter with resultant low energy requirement and running costs. Natural daylighting will be maximised wherever possible to provide a pleasant internal environment and reduce reliance on artificial lighting.
Work is currently on site, with some unusual spectators.
Planning consent has been granted for a pair of Passivhauses in Camber, East Sussex.
The buildings will be super insulated, minimising heat losses and maximising passive solar gain and natural daylighting. The site is very challenging; orientation is opposite to what would be preferable for passive solar design, neighbour amenity issues and flood risk.
During last year’s weird weather, we had periods of heavy rain following drought. This caused extreme stressing of the sewage network, resulting in the overflow of vast quantities of raw sewage into the Channel, which made many of our most popular beaches unusable. None of us would like to swim in polluted water.
However, we seem to be less fussy about breathing polluted air. Research has shown that in many houses, schools and offices, we breath in a cocktail of chemicals which can be harmful to our health. These result from the activities in our buildings, the furniture, machinery, paints, and carpets.
Most houses are naturally ventilated, research shows that ventilation rates can vary hugely, depending on wind speed and weather conditions. 0.3 air changes an hour per person is recommended.

The first residential passivhaus Conker ever worked on is a detached, traditional looking cottage in Chilham, near Canterbury. The design work started in 2005, when hardly any information was available in the UK. Our client embraced the principles of Passivhaus and started work in 2007. Progress continues at a steady pace.
Our client kindly opened his house to the AECB’s Pedalhaus Tour on 21 May 2011 to talk about his experiences. He had hoped to complete by Christmas 2012, but this has moved on to 2013. His chickens are keeping an eye on things and doing well!
Keep up the good work!
Conker’s offices in 1942 following an air raid.
In reprisal for RAF raids on non-military targets in Germany, the Luftwaffe started to target cities of historic significance in the UK based on the ‘Baedeker’ travel guide books. Cities bombed included Exeter, Bath, Norwich, York and Canterbury. Stour Street was hit on 1st June 1942.
Thankfully our relations with Germany are now entirely PASSIV!
Subsidence, front and side elevations leaning, severe condensation, plastic cladding, 30mm wide structural cracks – not the ideal starting point for an ecologically sound refurbishment.
Our brave client is undaunted by this task, and intends to create a fine example of energy efficiency using natural breathable materials.
Many difficult challenges have arisen during the detailed design, balancing cost, complexity, performance, buildability.
Follow us to see progress.

Air tightness is an essential part of a refurbishment or new build.
The Passivhaus standard requires a maximum figure of 0.6 air changes per hour, or 1.0 ach for refurbishment to the EnerPHit standard.
This table shows figures achieved on recent projects that we have been involved with to some extent. It shows that the method of construction has little influence on the final result; but contractors with most experience do best. The current award goes to Ecolibrium Solutions Ltd. Any challengers?
Work is progressing on site for a new 4 bedroom passivhaus in Faversham. Conker managed to obtain planning permission in December 2008 for the site in a dense residential area of the town centre, which suffered from considerable overlooking. This was partly due to a considerate and responsive design solution, partly due to the hard work by the client in liaising with the 32 neighbours, and partly due to a very positive and constructive planning department at Swale Borough Council.
As the client is a specialist in renewable energy, the scheme naturally includes solar PV, solar thermal, plus pipework underground for testing heat pumps and ground cooling systems.
After many years of promoting and practicing the passivhaus standard, Paul Mallion has taken the Passivhaus Institute exam and passed.
He is now recognised by the PHI and is listed on the www.passivhausplaner.eu database, one of only 3 chartered surveyors in the UK and Ireland.
Paul Mallion has been elected Fellow of the RICS by achievement. This was based on Paul’s contribution to the profession in regard to sustainability and energy efficiency.
It is not true that he now has to grow a beard!
Conker has been assisting a local group in saving the unique and historic Westgate Hall from demolition. On 28 July 2011 Canterbury City Council agreed to save the building and grant a 99 year lease to the Westgate Community Trust from March 2012. The hall will be preserved, refurbished and managed as a community centre.

Conker Conservation Ltd are working on designs for a Passivhaus Standard primary school in Kent. Colliers Green School is a very successful rural school, with very forward thinking Head, staff and governors. They were dismayed at the apathy displayed by conventional designers when given the brief for an ultra-low energy building. No so at Conker, we have researched primary school design in the UK and found many exemplary buildings completed in the last 10 years.
Regrettably, these are dwarfed by the number of average buildings with poor energy performance, almost none meet the DECC guidelines for electricity consumption.
A passivhaus school recently completed in Redberg, near Frankfurt has given us confidence that we can achieve the standard. Fund raising is currently underway.
