Building and process performance
Target the systems that materially affect consumption, cost, reliability and production efficiency.
Explore performance services
Engineering-led energy, compliance and performance support for manufacturing sites where process demand, utilities and production reliability must be considered together.
Manufacturing demand changes with product mix, shifts, throughput, maintenance and the condition of process and utility systems.
Site-wide invoices rarely show whether waste sits within production equipment, compressed air, steam, refrigeration, HVAC, power distribution or out-of-hours operation.
Zerith focuses assessment on the largest consumers and operational constraints first, creating a targeted programme that protects output and prioritises commercially credible action.
Product mix, shifts and throughput can make simple year-on-year comparisons unreliable. Performance needs to be read alongside relevant production context.
Compressed air, steam, refrigeration, power distribution and other shared systems can be difficult to distinguish from production consumption in site-wide data.
Any improvement must be considered against quality, maintenance, safety and continuity of production—not energy in isolation.
What drives the cost: explore a factor to see how it can affect energy cost per unit produced.
Pre-assessment helps define an efficient scope and investigate the largest energy consumers with the greatest commercial relevance.
Relate energy use to relevant production and operating variables so sites and processes can be compared on a more meaningful basis.
The question: which systems materially shape cost and output?
Engineering review · Operational contextThe aim is a prioritised programme of low-risk operational improvements, planned upgrades and longer-term investment decisions.
Connect engineering insight, compliance evidence and portfolio context to a practical next step.

Zerith manages the programme from initial assessment and data analysis through prioritisation, implementation support and verification.
Your internal team leads delivery, using ZECO and Zerith’s specialist support to strengthen analysis, consistency and quality assurance.
Internal teams manage routine activity while Zerith supports complex engineering, modelling, compliance and investment decisions.
Independent expertise. Practical outcomes.
Zerith combines more than 50 years of collective consultancy experience with hands-on expertise across building performance, energy compliance, infrastructure and Net Zero delivery.
The team brings CIBSE Low Carbon Consultant capability, ESOS Lead Assessor expertise, CIBSE Heat Network Consultants, ISO 50001 assessor capability and IES VE Level 3, 4 and 5 modelling.
Manufacturing recommendations are considered alongside production, quality, maintenance, safety and business continuity.
Low-carbon consultancy capability to support engineering review and energy improvement planning.
ESOS assessment support aligned with the organisation’s qualifying status and operational needs.
Specialist support where heat networks form part of the site’s energy and engineering context.
Assessor capability to support energy management system review and evidence.
Advanced modelling capability to help examine scenarios and support planning decisions.

The scope is planned around operating constraints, safety requirements and available shutdown periods. Data analysis and pre-assessment help focus site time where it adds value.
Yes. Zerith can examine production demand, utilities and building systems, bringing in appropriate specialist evidence where the process requires it.
Support can include ESOS, SECR, Climate Change Agreements and ISO 50001, aligned with the organisation’s qualifying status and operational needs.
ZECO can use production, operating-hour and site-context variables so performance is compared on a relevant basis rather than through raw consumption alone.
Yes. Client-led and hybrid models allow site teams to undertake routine data and implementation activity with Zerith providing structure, specialist review and quality assurance.
Start with a focused discussion about production, utilities, compliance and the consumers most likely to offer meaningful savings.
