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.

01 - STRATEGY

Energy and carbon strategy that turns 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
02 - OPTIMISE

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
03 - DE-RISK CAPITAL

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.

Nulla Console - Beaconsfield
▸ What's driving the overnight electricity spike?
Two AHUs (Plant Room 3) are running 22:00-05:00 against an empty building. At 7.5 kW each, that's 105 kWh (~£26) wasted a night. Recommend scheduling to occupancy - est. £9,600/yr saved, zero capex.

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 costed and commercially justified. We've saved clients millions per project by de-risking capital.

Let's make your buildings perform.

Whether you need a strategy, better-run systems or a capital project that stacks up, start with a building review and we'll show you where the value is.
