Retrofit Existing Buildings

Aus 04

Retrofitting or renovating an existing property can significantly reduce your annual heating
energy requirements and carbon dioxide emissions by between 75 and 90% compared to an
average existing building.

Retrofit applies to any renovations that are to be carried out to an existing building, whether
it is a house, university, school or office, that improves the energy efficiency and reduces
it’s ‘carbon footprint’.

The energy losses in a typical existing house are approximately as follows:


We have found that the following key measures have proved to be particularly effective:
• improved thermal insulation,
• reduction of thermal bridges,
• improved air tightness,
• use of very good quality windows,
• ventilation with highly efficient heat recovery

Where to begin?

Aus 02

One of the challenges with existing buildings and homes is that each and every one is
unique and also has its own interesting choices.

At Integrity we firmly believe that each home or building needs to be looked at in isolation,
we also understand that our clients cannot always afford to carry out the all the necessary
works at any one time and are looking for a phased approach. We therefore look carefully at
a stepped approach, looking at each possible stage, the cost and also importantly planning
the works so that, works carried out today, do not have to be removed to enable the next
phase to take place at a later date.

The Approach

Low Energy = Low Carbon

To ensure carbon reduction, sustainability, energy efficiency, and comfort, we need to:
• Consider design requirements
• Look at materials and methods
• Creative and practical solutions
• Model and calculate proposed works
• Produce cost effective programme

We also need to achieve:
• Constant air temperature
• Uniform surface temperatures
• Draft free spaces
• Managed humidity

Works to be looked at as a whole-building approach, even if works are phased.
