Problem
Buildings often operate inefficiently because their live operational data is not analyzed or acted upon, leading to wasted energy and occupant discomfort. Traditional engineering consultancies may identify problems but often fail to deliver the hands-on implementation and follow-through needed to achieve real, lasting performance improvements.
Solution
nulla.energy acts as an engineering partner that connects to a building's live data sources—including BMS, energy, water, sub-metering, and occupancy—to understand its actual performance. The company pinpoints inefficiencies and delivers projects to improve performance, covering the full spectrum from energy audits and ESOS compliance to BMS optimization and capital project de-risking. By keeping engineering, data, and delivery under one roof, they ensure that recommendations are turned into actionable, implemented measures. Their approach includes cost-optimizing contractor quotes and treating buildings holistically to avoid overspending or specifying incorrect measures in isolation.
Target Audience
Primary customers are building owners, facilities managers, and real estate teams seeking to reduce energy consumption, achieve net zero targets, and improve occupant comfort through practical, data-driven engineering projects.
Features
- Energy audits (Net zero, ESOS) that produce costed measures and performance specifications, ready for RFP
- BMS and operational optimization that connects to all data sources via API for controls tuning and demand control
- Capital project optimization including holistic retrofit strategy and heat pump design review
- Unified data platform that structures BMS, energy, water, sub-metering, occupancy, weather, and field data in interoperable formats
- Hands-on delivery with site teams to implement changes, not just provide reports
