The operating reality
Commercial buildings rarely operate exactly as designed.
Occupancy, lease arrangements, tenant activity and changing space use can all create a gap between design intent and day-to-day performance.
Schedules and controls drift while energy costs, compliance obligations and expectations for asset performance rise. Zerith combines engineering review, operational evidence and portfolio intelligence to identify improvements that protect occupier experience and asset value.

Where we look
Find the operational and investment priorities that improve asset performance.
Zerith combines site inspection, energy data, controls review and asset context to understand where cost, compliance and performance risk intersect.
Engineering review
HVAC schedules, setpoints and zoning
Review heating, cooling and ventilation schedules against building use, tenant requirements and actual operating demand.
The question: are controls supporting the way the building is used today?
Evidence-led engineering reviewThe aim is a prioritised programme of low-risk operational improvements, planned upgrades and longer-term investment decisions.

Frequently asked questions
Clear answers for complex estates.
Can you support both landlords and tenants?
Yes. Zerith can help define responsibilities and review the systems, information and operational areas under each party’s control.
Can operational improvements be made without major refurbishment?
Often there are opportunities to review schedules, setpoints, sensors, plant sequencing and building management systems before considering larger capital works.
How does compliance support asset performance?
Evidence prepared for requirements such as ESOS, MEES, SECR, NABERS or heat networks can also help expose priorities for wider asset-performance review.
Do you support acquisition and refurbishment decisions?
Yes. Support can include due diligence, modelling, investment appraisal and independent engineering input to inform property and refurbishment decisions.
Can ZECO compare different building types?
Yes. Properties can be considered by relevant context such as use, size, occupancy, systems and operation to make portfolio comparisons more meaningful.
