Climeaction Case Studies
Overview
A leading medical manufacturer in Georgia engaged Climeaction to evaluate its energy-intensive multi-building campus through the FAST program, targeting optimisation of steam, chilled water, and HVAC systems.
The Challenge
The site relies on steam distributed across most buildings, extensive chilled-water systems, and a mix of fab, lab, warehouse, and operations spaces. Total site energy consumption in 2024 was about 80.7 GWh across electricity and fuel, with electricity use of about 42 GWh per year and strong summer peaks driven by cooling and HVAC fans. Market-based Scope 2 emissions have been eliminated through renewable procurement, while Scope 1 remains dominated by natural gas for boiler steam.
Thermal and HVAC needs are substantial due to process loads, cleanroom operations, and space conditioning. Complexity is heightened by a multi-decade campus with mixed-vintage systems across numerous buildings and a central steam distribution network. Natural gas usage shows both weather-correlated space-heating demand and a non-weather base load for year-round process needs. Growth and ongoing expansions increase total energy demand, which makes achieving corporate targets more challenging without a coordinated plan that protects production and quality.
The Solutions
FAST Opportunity Mapping and Decarbonisation Roadmap
Climeaction applied the FAST framework to map significant energy users across steam, HVAC and cleanroom air, chilled water, compressed air and process utilities. These insights were translated into a prioritised opportunity register and delivery roadmap.
High Value Portfolio of Energy and Cost Savings
The portfolio identifies more than 25 decarbonisation opportunities, modelling over 1.45 million dollars per year in cost savings, approximately 15.8 GWh in electricity savings, 18.8 GWh in fuel savings and roughly 3,419 tonnes of CO₂e reductions. The full programme demonstrates a strong business case, with an estimated NPV of 11.2 million dollars, IRR of 17.5 percent and a simple payback of 4.8 years.
Waste Heat Recovery Basis of Design
A central outcome is a comprehensive Basis of Design for waste heat recovery. The system captures heat from key utilities and processes and redeploys it to building heating and reheat services. This solution targets boiler driven steam demand and is designed to displace significant fossil heat while meeting temperature, resilience and operational reliability requirements.
ISO Aligned Governance, Measurement and Verification
The plan establishes ISO aligned routines for governance and measurement and verification, ensuring opportunities can be tracked, validated and embedded into ongoing performance management.
Engineering Capability and Implementation Pathway
Climeaction defined the on site engineering bandwidth required to progress priority opportunities into metering plans, control sequence updates, detailed design and tender input, creating a clear and structured implementation pathway.
