Energy consulting
Engineer-led advice for residential and non-residential buildings: survey, renovation roadmap, heat load and heat pumps, funding and economics – as a listed federal energy efficiency expert.
Engineers who advise, plan and support landlords across the Rhine-Main region – practical, manufacturer-neutral and costed with figures that hold up.
Two services from one engineering practice: we advise owners and landlords on refurbishment – and take the modelling work off energy consultants' hands.
Engineer-led advice for residential and non-residential buildings: survey, renovation roadmap, heat load and heat pumps, funding and economics – as a listed federal energy efficiency expert.
We turn existing building plans into a three-dimensional building model that you continue working on in your own software. Assessment and professional responsibility stay with you – the time-consuming modelling is done by us.
What to expect for heating oil, natural gas and district heating is set out on the CO₂ cost development page.
Four building blocks that come together in every project, whether it is a single-family house or a large apartment building.
Developed from the building's condition and use – practical, technology-open and manufacturer-neutral.
Engineering and business expertise produce reliable figures you can base a decision on.
We use the allocation options the law allows, so the investment stays viable and tenants are relieved over time.
We guide you through planning, contractor recommendations and funding applications through to completion.
Our planning reduces CO₂ emissions and creates lasting benefits for landlords and tenants at the same time:
How refurbishment costs can be passed on and depreciated is explained under levies and depreciation.
More than two-thirds of all residential buildings in Germany are energetically outdated. That is the largest CO₂ savings potential of our time, and it is exactly where we work.
We come from industry, think in systems and work precisely and pragmatically – so that heat pumps and building automation actually perform in an existing building.
Our solutions are technology-open and manufacturer-neutral, tailored to the property in front of us. We do not sell equipment.
Business expertise gives realistic amortisation figures rather than the most flattering calculation available.
K&S Energy is entered in the German federal list of energy efficiency experts – the precondition for BEG funding through KfW and BAFA. More about us
A first conversation costs nothing and usually settles whether a measure is worth doing – and in which order – before you commission anything.
