Reversible air conditioning
Bearable summer comfort and back-up heating in the mid-season.

Ducted air conditioning
An invisible system: the unit is hidden in the loft or a false ceiling and air is delivered through discreet grilles.

Heat pump
Replace an energy-hungry heating system with one sized for your home and your emitters.

Thermodynamic boiler and water heater
Replace an oil or gas boiler, or produce your hot water using the heat in the air.

Solar panels
Produce part of your electricity, use it on site and sell the surplus if you wish.

Insulation
Limit heat loss in winter and overheating in summer, starting with the roof.

Whole-home energy renovation
A coherent programme, in the right order, carried out in one go or in stages.

How to choose?
The right order is generally to reduce needs first (insulation, solar protection), then equip the home (heating, air conditioning), and finally produce part of the energy you consume. An adviser helps you set your priorities.
Businesses and investors: solar investment.
