Make your buildings
run better.
We're the engineering partner that connects to your building's live data to understand how it really runs. We pinpoint inefficiencies others miss, and deliver projects to improve performance - so your building uses less energy and keeps its occupants happy.
What we do
Three ways we make your buildings perform.
Anybody can walk into a building and tell you what's wrong. The hard part is making change happen. That's where we're different - engineering, data and delivery under one roof.
Energy audits that turn into action
Net zero audits, ESOS compliance and feasibility studies - but not the kind that gather dust. We identify the measures and develop the specifications, so you get a ready-made RFP to take to market.
- Net zero & ESOS audits
- Engineering feasibility studies
- Costed measures & performance specs
- Procurement support to market
BMS & operational optimisation
We connect to your BMS and every data source we can - energy, water, sub-metering, occupancy - bring it into one place, and find the savings hiding in plain sight. Then we work with your teams and contractors to implement.
- Connect & analyse everything via API
- Controls tuning & demand control
- Additional sensing where it pays
- Hands-on delivery with site teams
Capital project optimisation
Retrofit is a system, not a shopping list. We cost-optimise contractor quotes from an engineering perspective and treat the building holistically - so you never overspend or specify the wrong measure in isolation.
- Holistic retrofit strategy
- Heat pump & heat decarbonisation design review
- Demand reduction, storage & bivalent options
- Cost-optimal sequence to your target
The platform underneath
One workspace for our engineers, one source of truth for your building.
We're changing how engineers work. Instead of jumping between Excel, Word, PowerPoint, modelling tools and data portals, everything lives in one place - every data source, every document, every site note and photo, structured into a single source of truth and made interrogable by AI.
Connect everything
BMS, energy, water, sub-metering, occupancy, weather and field data - unified in structured, interoperable formats.
Ask, don't dig
Instead of churning through half-hourly data, just ask. "Why is my AHU running out of hours?"
A living asset register
AI reads your site docs, photos, notes and conversations into a single source of truth, beside your live operational data.
Modular, AI-native workspace
Our engineers can pull data, run calculations, and flag operational issues in a single window. Less context-switching, more efficient engineers.
How we work
From data to delivery - and everyone on board.
We work with your incumbent supply chain, not around it. Site teams, regional managers, sustainability leads and contractors - we make sure everyone gets something out of the project.
Connect
Link the BMS and every data source we can reach via API.
Analyse
See exactly how the building is running and where the waste is.
Engage
Bring site teams and contractors together around the plan.
Implement
Make the change happen, then measure and verify the savings.
Why Nulla
The full stack of forces to make change happen.
What makes our team special: we're computer scientists, data analysts, engineers and engagement experts - everything you need to understand a building and move it.
Root cause, properly
We fix the system, not the symptom - and we treat the building as one connected whole.
People first
Guest comfort, the bottom line, carbon, time saved - we manage the impact on everyone involved.
Fast, and now
Early wins with little to no capital. We build momentum instead of writing reports that stall.
Commercially real
Every recommendation is ROI-led. We've saved clients millions per project by de-risking capital.
Let's make your building run better.
Even in buildings that seem well run, savings can be significant. Book a building review and we'll show you what's possible.
