About WEESS:Building Power as an Infrastructure Standard
WEESS fundamentally rethinks building power. As a technology house, we develop a standardized building energy infrastructure that turns multi-tenant buildings into independent energy assets – physically clean, economically robust, and regulatory compliant. WEESS building power is more than tenant power: it is an infrastructure standard.
We see energy as a system.
We do not view energy as a loose collection of products, but rather as a technical and operational challenge. That is why we develop solutions that are not only well-planned, but can also be implemented smoothly and operated reliably.
We develop energy systems from the ground up. This means that we first look at the building, its use and operational requirements, rather than focusing on a single product. This results in solutions that are technically well-structured, remain straightforward in everyday use and do not fail due to a lack of system logic.
Energy can be complex. But it shouldn’t be unclear.
Our aim is to provide an energy supply that is secure, sustainable and cost-effective, and that works in practice.
System rather than retrofitting
Storage, distribution, control and utilisation are not simply brought together as an afterthought. We develop the solution as a coherent system.
Solutions for residential buildings, tenant electricity and commercial energy projects
Our aim is to provide an energy supply that We are working on energy solutions for different types of buildings and project sizes. What they all have in common is a clear technical structure and a distinct role within the overall system.
From individual plants to networked infrastructure
Whether it’s a private residential building or a commercial site with more complex requirements – our solutions follow the same basic principles: technical clarity, scalable system logic and a structure that remains robust even as projects grow.
- 01-
Private customers
For residential buildings and private PV projects where self-consumption, storage and control are designed to work together within a clear system logic.
- 02-
Building electricity and tenant electricity
For apartment blocks and housing developments where locally generated energy is to be distributed, monitored and utilised within the building.
- 03-
Commercial
For locations where energy flows are organised, loads are more predictable and storage is considered part of the operational infrastructure.
- 04-
Grid-connected and larger-scale storage projects
For applications in which storage is used as a flexible infrastructure component and technical scalability is a key priority.
Understand first. Then build sustainably.
We don’t start with the product name, but with the task at hand. This results in a structure in which every component has a clear function.
- Clarify requirements
The first step is to ask what a building, site or project actually needs and what role energy should play there.
- Structure the system logically
Based on these requirements, we develop a solution in which generation, storage, distribution and control are technically integrated.
- Leading the way in implementation
We design the technical structure in such a way that planning, installation and subsequent operation do not conflict with one another.
- Ensuring transparency in operations
What is crucial is a system that not only works today, but also remains understandable and robust in ongoing use.
For owners, project partners and companies with specific energy requirements
We operate in areas where energy is not merely consumed, but must be planned, distributed and organised effectively.
Owner and asset manager
When energy needs to be utilised in a building in a cost-effective and structured manner.
Housing developments and apartment blocks
When local generation, distribution and consumption need to be integrated into a clean building system.
Commercial sites
When storage, control and transparent energy flows are to become part of a resilient location concept.
Project and implementation partner
When technical solutions need to be carefully planned and systematically developed, rather than improvised.
Because good energy solutions only prove their worth once they are up and running
We operate in areas where energy is not merely consumed, but must be planned, distributed and organised effectively.
Clear roles in the setup
Each component performs a specific function within the system. This ensures clarity in planning, implementation and operation.
Clear project logic
Solutions arise from the specific application rather than from a random selection of products.
Designed with technical and practical considerations in mind
We develop systems not just for installation, but for everyday use afterwards.

Frequently asked questions
We develop energy solutions for residential buildings, apartment blocks, commercial applications and other project-specific areas. Our focus is on systems with a clear technical structure.
WEESS was founded in 2022.
The focus is on comprehensive solutions. We do not view products in isolation, but rather in terms of their role within a functioning overall system.
For projects involving the generation, storage, distribution and control of energy, from private residential buildings to commercial sites.
We approach things from a project-based perspective. This results in setups where technical components do not simply sit side by side, but work together logically.
The process begins with the project: the building, its use, requirements and vision. On this basis, we develop the appropriate system logic.
