Example 1: Multi-Site ESOS - Commercial Real Estate
Client: A national Commercial Real Estate organisation operating a portfolio of 50+ office buildings of varying sizes, ages, and construction types, with a diverse range of building fabrics and mechanical and electrical systems.
The client has made a proactive investment in maintaining up-to-date EPCs across the portfolio and is concurrently undertaking Minimum Energy Efficiency Standard (MEES) reviews to assess compliance risk and future improvement requirements at both asset and portfolio level.
Traditional Consultancy Approach: An external consultant is appointed to carry out the ESOS audit, prepare the compliance report, and provide ESOS Lead Assessor sign-off. The process is largely outsourced, with limited client involvement and minimal long-term capability retained in-house.
The Zerith Approach: ESOS compliance is delivered by the client’s internal team using the ZECO AI platform, with Zerith providing structured pre-audit and post-audit guidance, quality assurance, and ESOS Lead Assessor certification. The process is faster, more transparent, and fully compliant—while building internal understanding of energy performance.
Cost Comparison
Projected cost reduction: Up to 60%
Estimated saving: Approximately £10,000 to £12,500 compared to traditional consultancy delivery

Example 2: Multi-Site ESOS - Manufacturing Client
Client: A complex industrial organisation operating two energy-intensive manufacturing facilities at separate locations, each supporting distinct production processes, alongside a separate distribution centre.
Energy and sustainability oversight sits with a central ESG Manager, responsible for portfolio-wide energy performance and strategy. Each manufacturing site is supported locally by a Site Engineering Manager, a Site Manager, and a Compliance/Health and Safety Manager, creating an in-house team with in-depth knowledge of the site, processes, and equipment. The site has previously submitted long-term capital investment plans and focused on identifying previously unseen energy-saving opportunities through ESOS.
Traditional Consultancy Approach: An external consultant is appointed to conduct the ESOS audit, prepare the compliance report, and obtain ESOS Lead Assessor sign-off. The process is largely outsourced, with limited client involvement and minimal long-term capability retained in-house.
The Zerith Approach: ESOS compliance is delivered through a client-led, structured energy assessment, in this case an Energy Treasure Hunt (could also be an Energy Audit, or Kaizen event), with Zerith providing hands-on technical support throughout the process. Zerith specialists actively support the on-site Treasure Hunt, ensuring energy-saving opportunities are identified quickly, accurately, and in line with ESOS requirements.
Following the on-site activity, the client’s Energy Manager completes the ESOS audit and evidence pack using the ZECO AI platform, supported by Zerith’s structured technical guidance, quality assurance review, and ESOS Lead Assessor certification.
This approach creates a more engaging and effective compliance process. It leverages deep internal knowledge of production processes, operational constraints, and building performance; increases energy awareness across teams; delivers full regulatory compliance; and builds lasting internal capability to manage and improve energy performance well beyond the ESOS cycle.
Cost Comparison
Projected cost reduction: Up to 50%
Estimated saving: Approximately £6,000 to £7,500 compared to traditional consultancy delivery

Net Result
Full ESOS compliance at lower cost, equal technical insight, and long-term organisational benefit—without reliance on expensive third-party consultancy.
Example 3: Manufacturing – Compliance Bundle
Example 2: Manufacturing – Climate Change Agreement (CCA)
Client: A complex, multi-site industrial organisation operating across energy-intensive manufacturing and support facilities, seeking to transition from outsourced consultancy delivery to an internally led model for CCA, SECR, and ESOS Phase 4 compliance.
Historically, compliance activities have been delivered by external consultants on a scheme-by-scheme basis. While the organisation already holds the vast majority of the required energy, production, and operational data, this information is siloed across sites and functions, often managed independently by engineering, finance, compliance, and ESG teams. The lack of a structured, standardised approach results in duplicated effort, limited visibility at the portfolio level, and an ongoing reliance on costly third-party support.
The client’s objective is to empower internal teams—at both site and central levels—to self-deliver compliance confidently and consistently, while improving data quality, transparency, and insight. This includes creating a repeatable, auditable process that supports regulatory submissions, enables cross-site benchmarking, and transforms compliance outputs into actionable intelligence for energy reduction and long-term Net Zero planning.
Traditional Consultancy Approach: Schemes are typically outsourced to a specialist consultant who collects site data, prepares the target unit calculations, completes the submission, and manages correspondence with the scheme administrator. The process is often opaque, repeated every reporting period, and reliant on ongoing consultancy spend. ESOS Processes completed as a turnkey solution
The Zerith Approach: compliance delivery is brought in-house and structured through the ZECO AI platform, creating a single, standardised framework for data capture, validation, and reporting across all sites and schemes.
CCA is delivered by site teams and central ESG functions using ZECO to structure energy and production data, calculate target unit performance, and complete submissions—supported by Zerith’s technical guidance and quality assurance.
SECR is centrally coordinated, with ZECO consolidating energy and fuel data across sites, applying emissions factors, and generating audit-ready disclosures aligned with statutory reporting timelines.
ESOS Phase 4 is delivered through client-led energy audits, Energy Treasure Hunts, or Kaizen events, with Zerith providing technical support, quality assurance, and ESOS Lead Assessor sign-off.
Throughout the process, Zerith works alongside internal teams to train, guide, and support delivery, ensuring compliance is accurate, repeatable, and transparent. Data is reused across schemes, improving efficiency and consistency while enabling cross-site benchmarking and deeper insight into energy performance.

Multi-site energy management is the coordinated control of energy use, carbon emissions, and compliance across multiple locations. It brings together data, systems, and teams to improve efficiency, reduce costs, and deliver consistent performance across an entire estate.
At Zerith, multi-site energy management is enabled through our ZECO AI compliance and performance tool. ZECO centralises scheme management for requirements such as ESOS, SECR, CCA, and Heat Networks, guiding internal teams through data capture, reporting, and submission using information already held within the business.
This replaces fragmented, site-by-site processes with a single, structured approach—providing greater visibility, reducing reliance on external consultants, and giving organisations long-term control over compliance, energy performance, and their Net Zero journey.
-
For manufacturing and industrial organisations, energy is a major input cost and operational risk. Rising and volatile energy prices, tightening regulation, and increasing pressure to decarbonise mean that unmanaged energy use directly impacts margins, competitiveness, and resilience.
These sectors typically operate energy-intensive processes, often within legacy infrastructure and complex production environments. Without structured energy management, inefficiencies remain hidden—driving unnecessary cost, carbon emissions, and operational risk.
Zerith supports manufacturers by turning energy reduction into a continuous, practical process, not a one-off exercise. We combine structured energy management with targeted energy audits, on-site energy treasure hunts, and Kaizen-style continuous improvement to identify and deliver real, measurable savings.
By working directly with site teams, Zerith uncovers operational inefficiencies, process losses, and quick-win opportunities that are often missed by traditional audits alone. These actions are prioritised based on impact, feasibility, and return on investment, ensuring savings are delivered quickly and sustained over time.
The result is:
Reduced energy and utility costs
Improved process efficiency and reliability
Lower Scope 1 & 2 emissions
Stronger compliance and risk control
An embedded culture of continuous energy improvement
For the manufacturing and industrial sectors, effective energy management—supported by Zerith’s hands-on approach—is essential to protecting margins, improving performance, and enabling a credible pathway to Net Zero.

At Zerith, energy efficiency in office buildings is delivered through a structured, data-led approach that focuses on real operational performance—not just design intent.
We start by understanding how the building is actually used, analysing energy data, building systems, and controls to identify inefficiencies and opportunities for improvement. This includes targeted energy and BEMS audits, optimisation of HVAC, lighting, and controls, and reviewing operational schedules to reduce unnecessary energy use.
Efficiency measures are then prioritised based on cost, impact, and return on investment, ensuring quick wins are delivered alongside longer-term improvements. Our approach is supported by the ZECO AI platform, which provides visibility, tracks performance, and supports ongoing compliance and reporting.
Crucially, Zerith works with on-site teams to embed knowledge and capability, ensuring energy savings are sustained over time. The result is lower energy costs, improved comfort, reduced carbon emissions, and a clear pathway toward Net Zero.
We begin by understanding how each site operates, analysing energy data, processes, and building systems to identify inefficiencies and high-impact opportunities. This can include targeted energy audits, BEMS and controls optimisation, process and plant efficiency reviews, and operational improvements tailored to the sector and site.
Efficiency measures are then prioritised based on cost, operational impact, and return on investment, ensuring quick wins are delivered alongside longer-term improvements. Our approach is supported by the ZECO AI platform, which provides estate-wide visibility, tracks performance, and supports ongoing compliance and reporting.
By working closely with site and central teams, Zerith embeds knowledge and capability within the organisation—ensuring energy savings are sustained, costs are reduced, and emissions are lowered across the entire portfolio.
-
In the hotel and hospitality sector, an energy management system (EMS) plays a critical role in controlling costs, maintaining guest comfort, and reducing carbon emissions—all while supporting round-the-clock operations.
Hotels are energy-intensive environments with highly variable occupancy, extended operating hours, and multiple energy demands such as heating, cooling, hot water, kitchens, leisure facilities, and laundry. An effective EMS provides real-time visibility of energy use, allowing operators to optimise systems based on occupancy, demand, and operational schedules.
At Zerith, we use energy management systems as part of a broader, integrated approach. An EMS enables hotels to:
Monitor and control HVAC, lighting, and hot water systems
Identify inefficiencies and abnormal energy consumption early
Optimise performance without compromising guest experience
Support compliance and sustainability reporting
Track progress against energy and Net Zero targets
Ensure BeMS System Optimisation
Begin the transition towards smart hotel systems, such as integrated room management via the hotel booking system.
When combined with structured energy management processes and engaged on-site teams, an EMS helps hotels reduce energy costs, improve operational efficiency, and deliver consistent comfort—making it a core tool for sustainable and commercially resilient hospitality operations.

Centralising energy performance starts with creating one consistent view of energy, carbon, and compliance across all locations. The challenge for most organisations is fragmented data, different systems, and site-by-site approaches that make comparison and control difficult.
At Zerith, we centralise energy performance using a structured framework supported by the ZECO AI platform. ZECO brings together energy data, compliance requirements, and performance metrics from multiple sites into a single system, standardising how information is captured, analysed, and reported.
This allows organisations to:
Compare performance consistently across sites
Identify high-impact energy efficiency opportunities
Share best practice and prioritise investment based on ROI
Manage compliance schemes such as ESOS, SECR, CCA, and Heat Networks from one platform
Zerith supports this with training, guidance, and targeted expert input, ensuring local teams are engaged while central teams retain visibility and control. The result is coordinated, scalable energy performance improvement across the entire estate.
-
Yes. At Zerith, carbon savings can be tracked at building level, site level, or across an entire portfolio.
Using the ZECO AI platform, energy and emissions data is captured and standardised, allowing you to calculate carbon baselines and track reductions over time for individual buildings. This provides clear visibility of where savings are being achieved and which sites are delivering the greatest impact.
Building-level tracking enables:
Accurate measurement of Scope 1 and 2 carbon reductions
Comparison of performance across sites
Verification of savings from energy efficiency projects
Evidence-based reporting for compliance and Net Zero targets
This level of visibility ensures carbon reduction is measurable, auditable, and directly linked to operational action—not just estimated at a high level.
