retrofit means adding new measures or technologies to your existing building
This is most usually done during a renovation. If you are looking to make alterations to your building, then adding low energy measures is surprisingly simple. Consider adding insulation, making your building airtight, adding new energy-efficient windows and installing ventilation with heat recovery - do this and the energy performance of your building will be dramatically improved.
greentomatoenergy has lots experience in very low energy retrofits. We can advise you on the best methods, design the technologies and recommend the best installers.
