We are aware of the importance of the environmental impact and energy consumption that households generate. For this reason, if the client so wishes, we can carry out the study, assessment and management of any installation supported by sustainable energy. The introduction of renewable energy, as well as taking advantage of existing natural resources, allows for a reduction in energy costs and consumption, the revaluation of the property, and access to grants to finance such. Sustainable architecture and energy efficiency are also part of LF91’s ideology.
