YOUR INTELLIGENT BUILDING ADVISOR
The future of buildings starts with how we think.
Marco Rutzke brings together software, entrepreneurship and a clear vision for intelligent buildings.
He has been working with software development and digitalisation since the age of 14. As the founder of NetTask and initiator of HXA.io, he sees buildings as connected systems that evolve with their users.
As a thought leader in software-defined buildings, he connects the owner’s perspective with the possibilities of digital technology. Together with the HXA team, he turns this thinking into a concept for your project.
SOFTWARE-DEFINED BUILDINGS
Architecture endures. Possibilities grow.
A software-defined building can adapt its functions to new requirements through software.
We consider spaces, technical systems and digital services together. Open interfaces and a coordinated data structure provide the basis for connecting bookings, access and room functions.
We start with people: how do they arrive, how do they work and which activities should the building support? These answers shape requirements for architecture, specialist design and future operation.
01
People & use
Working, arriving, meeting
02
Digital building layer
Identity, booking, rules, data
03
Systems & spaces
Access, lighting, climate, resources
PLANNING TOGETHER
Your project sets the direction.
For building owners
Clarity before you invest.
Which digital functions create value? We prioritise requirements, consider implementation and operation, and define sensible stages of investment.
For architects & designers
Design for digital needs early.
We translate use cases into coordinated requirements for spaces, interfaces and infrastructure, working with your architectural and building services design teams.
For developers
Make flexibility part of the project.
We structure the digital base specification and potential tenant options, so future changes of use are considered from the outset.
OUR ADVISORY SERVICES
Advice with a concrete outcome.
From an initial conversation to delivery support. The scope follows your project stage.
01
Opportunity assessment
The right questions first.
We review your project or existing building and discuss objectives, user groups and current systems.
Your outcome
Prioritised use cases and a clear recommendation for the next steps.
02
Digital building blueprint
A shared foundation.
We develop use cases, system architecture and interfaces. Responsibilities and stages of delivery are coordinated with your design partners.
Your outcome
A digital concept to support design and procurement.
03
Delivery support
Bring the concept into daily use.
We support design coordination, review solutions against agreed requirements and assist with pilots and functional checks.
Your outcome
Verified workflows and preparation for future operation.
DESIGN AROUND USE
One meeting. A coordinated experience.
What should happen when a meeting room is booked?
One possible design scenario: authorised guests receive access. The room is prepared for the meeting. After use, the agreed room functions return to their idle settings.
We work with you to determine which steps make sense and which systems, permissions and interfaces are needed.
- Before arrivalBooking and access permissions
- During useRoom comfort and available services
- After the meetingRelease and demand-based operation

PERSPECTIVE
Software-defined Buildings
Why SMEs should consider digital buildings a strategic opportunity. By Marco Rutzke, with Celina Distler.
BACKGROUND
The software-defined building
An overview of the terminology, architecture and applications of software-defined buildings.
FAQ
Good to know.
When should we involve your team?
Ideally during the concept stage, when uses and requirements are taking shape. We can also review decisions in an ongoing project or existing building and identify a suitable starting point.
Does this replace our specialist designers?
We complement architecture and building services design with a digital usage perspective and system integration expertise. Scope, responsibilities and handovers are agreed for each project.
Do we have to use HXA products?
Your requirements and existing systems are the starting point. As the team behind HXA.io, we bring our own technology. Where it fits the concept, we make its proposed use clear and review the interfaces required with other solutions.
How do we get started?
In our first conversation, we discuss your project, its stage and your goals. We then propose a clearly scoped engagement, such as a paid opportunity assessment.
YOUR NEXT STEP
What should your building be able to do tomorrow?
Discuss your project with Marco Rutzke and the HXA team.
