How to assess sustainability benefits and business value

Defining The Market For Energy Efficiency Solutions

This report analyses the maturity, proven business value and future direction of energy efficiency solutions targeting climate change and sustainability challenges. Verdantix defines energy efficiency solutions as: Products or services that increase the energy efficiency of a site, a building, a process or an asset by directly or indirectly reducing the energy required to achieve the same business results.


The Verdantix Total Portfolio analysis of energy efficiency solutions helps executives and managers to make better informed decisions on investments in energy efficiency solutions and energy consuming assets linked to business sustainability programs. The analysis also helps product and portfolio managers in energy solution providers to understand the current state of the ecosystem for energy efficient products. The analysis covers LED lighting, PC Power Management, Voltage Optimisation, Variable Speed Drives, HVAC Controls, Building Management Systems (BMS), Insulations, Lighting: Occupancy Controls, T5/T8 lighting controls and Boiler Controls which is detailed below.

Boiler Controls


The harmonising of a boiler’s output to match site demand through automated modulation of the boiler. More intelligent systems will prevent boiler cycling, associated with oversized boilers. They can be installed as a standalone system or integrated within a BMS.

Maturity Phase:

Growth. This solution has been widely implemented within the commercial and industrial sectors. Adoption by smaller energy consumers has been limited. Uptake of intelligent boiler controls is still growing.

Business Value:

Moderate. Through automatic output modulation and the limitation of boiler cycling, gas consumption and CO2 emissions can be reduced by 10 per cent to 25 per cent. The payback period for boiler controls is typically between 6 months and 2 years.

Sustainability Rating:

4. Increases in efficiency result in lower consumption rates and reduced CO2 emissions. However the boiler remains a significant consumer of energy.

Investment Advice:

Boiler controls are advised for both commercial and industrial sector. The effectiveness of linking boiler controls to a BMS depends on the level of intelligence. When looking to avoid boiler cycling it is advised companies install stand alone controls.
