Would you like to know how you could benefit from major savings on energy costs in your building? We will be pleased to accompany you on the way to your goal and support you in word and deed.

Existing structures are losing their energy efficiency ratings due to new technologies and building standards. A comprehensive renovation will put things right and significantly reduce energy consumption. Our team of experts is exactly the partner you need for purposeful, efficient planning and implementation. We will ensure that your project runs smoothly whilst avoiding unnecessary costs through our broad experience, know-how and forward-thinking approach. You can count on us at every stage from consulting to planning through to execution and subsequent acceptance. Each of these three steps is a project in its own right for which we will provide a separate bid and explain in detail – so that you are always free to decide on how you wish to proceed. Another plus: you will have your own personal contact partner during every phase of the entire project.

This is what the Energy+Renovation Division can offer you


Our team of experts will prepare an energy-based building analysis following a non-binding, informative discussion at your premises. We will uncover any weak points in the building’s fabric and management systems, inspect, examine and assess the existing building substance and provide you with renovation suggestions that will have a sustainable positive effect on your building and maintain the value of your property. We also take care of the legal aspects, explain potential grants that may be available to you and produce a detailed cost-benefit calculation.


Once the building analysis is complete, we then take care of project planning and calls for tender. This includes, when necessary, submitting an application for building permission and publishing the required trades. In a subsequent step, we will compare the bids together with you and draw up the contracts to be awarded to the selected companies. You do not enter into any obligations as contractor and are free to choose your preferred tradesmen. The execution of the project is carefully planned and scheduled in parallel.


We supervise construction as your appointed site manager or offer our services as a general contractor. We will provide you with continuous, transparent updates on current costs and carry out construction cost accounting on your behalf. We adopt responsibility for construction work up to the acceptance and handover of your renovated building. 


Our team consists of five professionals in the field of "Energy+Renovation". You will always have a personal contact partner at Weiss+Appetito who will take care of your interests and concerns throughout the duration of the project, from consulting to planning through to execution.
