MyPassivHaus.uk will document my attempt to get a 1930 semi-detached house, from its existing state, with solid walls, cheap double glazing, poor roof insulation and a north facing "conservatory" upto Passiv Haus standards. Ideally, I want to be able to reduce the heating bills to almost zero.

The items I want to cover (in no particular order) are

• Roof insulation
• LED lamps througout
• Heating system improvements (TRV)
• Triple glazing
• Low U value external doors
• Heat recovery ventilation system
• Conservatoy / Trombe wall on south west side
• Large insulated porch on south east side
• Replace conservatory with extension on north west side
• Solar thermal installation for hot water
• Solar thermal system for heating
• Solar PV system for electricity
• Underfloor insulation & heating system
• Season thermal energy store

We are still very early days and investigating all the options. Money is also quite tight, so it won't happen all at once.
