On the 22nd April the design team and installers met at the property with the resident to carry out further feasibility surveys.
Having all contractors together on site proved to be a very valuable exercise enabling the different specialists to discuss how their equipment would fit together, timings for works and allocation of responsibility for each part of the project. For example the external wall insulation company were able to discuss with the thermodynamic solar energy supplier how the panels could be fixed to the external wall through the insulated wall system and where to locate pipe-runs. Opportunities were identified to reduce the amount of visible pipe-work and co-ordinate the two work programmes saving time as the project develops.
All the works will take place with the resident in-situ. It is recognised that this will be disruptive especially elements such as insulating the floor and some of the internal walls. Throughout the project the resident has been kept fully informed of the proposed works. The day gave her opportunity to meet the different contractors, highlight her concerns and input into the specification for different elements of the works, e.g what window finishes she would like.
Difficult issues such as temporary sanitation and cooking facilities and protection of personal belongings were discussed and solutions reached with full cooperation of the resident.
The team is now moving rapidly forward with the detailed specifications, and works programme.

Project Aims
We hope to demonstrate a whole house solution which will result in significant carbon and primary energy reduction. The solution was developed to be replicable across a large proportion of the UK housing stock, and to enable UK businesses to meet a national scale up.
The property has been extensively analysed and monitored to give a baseline starting point energy consumption.
Our modelling shows that the measures to be carried out will reduce fuel bills by 94%
The Property
The solid-walled semi detached house is traditionally regarded as hard-to-treat. There are no wall cavities to be filled and the façade has architectural features that we do not want to change.
The works
Insulation will be added to all the heat loss surfaces.
A thin layer of high performance aerogel will be added internally to the front façade. External wall insulation will be added to other surfaces and finished to look the same as the current walls.
Vacuum insulated panels will be added to the floor, stopping heat loss and draughts, without a large increase in floor height.
Underfloor heating will replace the storage heaters. Hot water and space heating will be provided by a heat pump whilst electricity will be generated from solar panels on the roof.
The cold porch will be replaced with a sun lobby which will capture spring and autumn heat, but not allow heat loss or gain to the house in the winter or summer.
It is important to understand that this is our tenant’s home. All the works will be carried out whilst she is still living in the property to the highest standards with disruption kept to a minimum.

Phase II
We have won funding to implement the Retrofit Works. Great news. Well done everyone. Time to put our theories into practice!
