Office building at night with the lights still turned on, wasting energy. BRIGHTER, the AI-driven software that optimizes HVAC for commercial buildings is the best solution to prevent energy waste

BRIGHTER is AI-driven software that optimizes HVAC for commercial buildings

BRIGHTER’s AI-driven software operates as an intelligent layer on top of the existing Building Management System (BMS) and HVAC installations, continuously optimizing 24/7 based on real-time data to deliver measurable, data-driven energy savings.

The benefits of BRIGHTER:

  • Immediate energy savings without costly renovations

  • Faster progress toward sustainability targets such as Paris Proof

  • Improved energy performance while maintaining indoor comfort

  • Often delivers payback in less than 12 months

  • BACS-ready, today and beyond 2030

  • Fastest implementation in the market

What is BRIGHTER?

BRIGHTER is software that automatically optimizes HVAC performance, reduces energy consumption and supports real estate portfolios in achieving BACS compliance through AI algorithms, real-time sensor data, and weather forecasting.

When is BRIGHTER the best choice?

  • When you want to significantly reduce the energy consumption of your buildings

  • When you aim to improve sustainability without costly hardware replacements or major capital investments

  • When a short payback period is essential

  • When indoor comfort must be maintained

  • When you need to comply with sustainability standards such as BACS

BRIGHTER is not the best fit for buildings without a Building Management System (BMS). Nor for residential buildings.

How does BRIGHTER work

BRIGHTER logo
  • Smart layer on top of the BMS: BRIGHTER operates as an intelligent layer on top of the existing BMS.

  • AI-driven HVAC optimization (24/7): BRIGHTER continuously controls climate systems using predictive algorithms based on real-time and historical data.

  • Weather- and environment-driven preconditioning: The system uses weather forecasts and solar radiation data to pre-heat or pre-cool buildings with minimal active energy use.

  • Elimination of simultaneous heating and cooling: BRIGHTER prevents conflicting system control, a structural cause of energy waste in traditional building operations.

  • Digital Twin technology: A digital replica of the building models thermal behavior and works across all HVAC types and existing BMS environments.

  • Automatic fault and anomaly detection: Algorithms identify deviations that traditional building management systems often miss, helping prevent complaints and technical failures.

BRIGHTER as the Most Effective Sustainability Measure for Commercial Buildings

What is the most effective sustainability measure for commercial buildings? Measured by energy savings and payback period, BRIGHTER outperforms every other sustainability measure assessed. The savings are based on realized results across more than 728,000 m² of managed real estate, spanning offices, healthcare facilities and hotels in the Netherlands.

When comparing sustainability measures, two variables are decisive. Energy savings are defined by the European Commission’s Energy Efficiency Directive (EED) as the measured or calculated reduction in energy consumption before and after an efficiency measure, corrected for external influences. Payback period refers to how quickly the investment is recovered based on realized savings, the criterion used by the Netherlands Enterprise Agency (RVO) to assess compliance with the statutory energy-saving obligation. Together, these two variables allow measures to be objectively compared on both a technical and financial level.

Comparison of sustainability measures for commercial buildings by energy savings and payback period (EED methodology). BRIGHTER delivers the best combination of both.
Sustainability measure Energy savings Payback period
BRIGHTER 28% 1-2 years
Sun protection and natural ventilation 10-30% 3-7 years
Energy-efficient appliances (A+++) 10-20% 3-7 years
Solar panels 20-40% 4-8 years
Roof, wall and floor insulation 15-30% 5-10 years
HR++ or triple glass 10-25% 8-15 years
Heat pump 40-60% 7-12 years
Underfloor heating 10-20% 10-15 years
Green or white roof 5-15% 10-20 years

Heat pump or HVAC optimization first: which delivers more?

The heat pump scores highest on energy savings: 40 to 60 percent. But with a payback period of 7 to 12 years and a significant installation effort, it is rarely the right first step. BRIGHTER optimizes existing HVAC installations without replacing them, delivering an average of 28 percent energy savings with a payback period within 12 months. The two are not mutually exclusive: BRIGHTER is the logical first step, with a heat pump a later consideration when installations are due for replacement.

Who benefits from BRIGHTER

BRIGHTER is used by technical asset managers, property managers and installers who are responsible for energy consumption and building performance, and who aim to achieve structural improvements without replacing installations or making major capital investments.

Average 28% energy savings

BRIGHTER demonstrably delivers an average of 28% energy savings at portfolio level.

Payback often within 12 months

The investment typically pays back within 1–3 years, frequently within the first year.

Reduced stranding risk

BRIGHTER helps assets remain compliant and leasable in a changing regulatory and market landscape.

Faster progress toward sustainability targets

The platform actively steers energy efficiency in line with CRREM pathways and Paris Proof objectives.

BACS-ready, now and beyond 2030

BRIGHTER enables buildings to comply with BACS Class A (for the control system component), the most stringent classification.
