Smarter Building Performance & Energy Control

Lower energy waste. Improve comfort. Take control of how your buildings really perform.

Energy performance is one of the biggest challenges facing facilities and property teams today. Rising costs, ageing systems, sustainability targets, and increasing pressure to do more with less.

That’s why Reactik Services has partnered with System5, part of 4Energy Group, to help organisations gain clearer insight, better control, and real, measurable improvements in how their buildings operate.

By combining Reactik’s facilities management oversight with System5’s building controls and energy expertise, we help clients turn complex building systems into something that actually works for them, not against them.

The Reality of Managing Building Performance

For many organisations, building systems and energy performance can feel like a black box:

  • Energy usage is high, but the causes aren’t clear

  • Building controls are outdated or poorly optimised

  • Comfort complaints keep coming in

  • Systems don’t talk to each other

  • Small inefficiencies quietly drive high costs

Over time, this leads to wasted energy, frustrated occupants, and buildings that never quite perform as they should.

A More Practical, Joined-Up Approach

Our partnership with System5 is about making building performance understandable, manageable, and efficient.

Together, we focus on optimising how building systems are controlled and monitored, helping clients reduce energy waste, improve comfort, and extend the life of critical assets.

This isn’t about ripping everything out. It’s about making smarter use of what’s already there, supported by the right expertise and oversight.

What This Partnership Delivers

Better Control of Building Systems!

System5 specialises in building controls and energy optimisation, helping ensure systems such as HVAC operate efficiently, reliably, and in line with how buildings are actually used.

Reduced Energy Waste

By identifying inefficiencies and improving system performance, energy consumption is reduced without compromising occupant comfort.

The result:

  • Lower energy costs

  • More stable building performance

  • Fewer complaints

  • Better use of existing infrastructure

Improved Comfort for Occupants

Well-controlled buildings are more comfortable buildings. Better temperature control, improved responsiveness, and fewer system issues all contribute to a better day-to-day experience for occupants.

Clear Oversight Through Reactik

Reactik manages coordination, visibility, and ongoing performance oversight, ensuring improvements are sustained, not just implemented and forgotten.

Who This Is For:

  • Facilities Managers

  • Property & Asset Managers
