Centralized energy distribution, backed by local and global expertise
Reliable, efficient and low鈥慶arbon thermal networks are reshaping the future of campuses and cities. District energy systems (DES) use centralized plants to generate hot water, steam or chilled water and distribute it through underground piping to multiple facilities. By consolidating energy production, DES improve efficiency, reduce emissions and support resiliency and energy affordability for universities, hospitals, airports and utilities as well as municipal and federal districts.
Since 1990, we鈥檝e supported district energy providers and public agencies worldwide. As part of a global, multidisciplinary infrastructure practice, we help clients plan, design and deliver district heating and cooling systems that integrate advanced heat鈥憆ecovery technologies, modernized central plant infrastructure and optimized network layouts.
Our services cover the full lifecycle of DES, from infrastructure design, energy master planning, business case development and feasibility studies to construction, operations, maintenance and delivery. We ground our work in technical excellence and global expertise, supporting communities seeking dependable, cost鈥慹ffective and low鈥慶arbon energy at scale.
Smarter planning for future-ready systems听
Decisions made today shape the performance of systems that may operate for more than 50 years. We partner with clients to assess current conditions and anticipate future demand, mapping all potential pathways for thermal decarbonization and long-term energy security.
Our planning services include:
- Energy master planning, decarbonization roadmaps and resilience planning
- Emissions assessments, feasibility studies and life鈥慶ycle analysis
- Campus and portfolio energy and load modeling with scenario planning
- Development of business case, commercial strategy and route to market
- District energy, renewable energy and microgrid concept design
- Planning and permitting
- Utility and infrastructure planning, system audits, contract and request for proposal (RFP)
- Expansion planning for growing campuses or new urban districts
We help clients compare technology pathways, understand lifecycle costs, and identify the most effective strategies for achieving reliability, energy security, operational savings and carbon鈥憆eduction goals.
Integrated capabilities across the district energy lifecycle听
We support district energy systems across their full lifecycle, bringing together electrical, mechanical, thermal, control, digital and civil expertise to deliver integrated, high-performing solutions in:
4th and 5th听驳别苍别谤补迟颈辞苍蝉听顿贰厂,听wastewater听and听effluent听heat听recovery, geothermal听and industrial heat recovery,听energy-from-waste听(EFW)听generation,听data center听heat capture, use of river听and听lake water,听thermal and seasonal energy storage.听
Combined heat and power (CHP) and trigeneration, EFW and biomass generation, and high-efficiency boiler, chiller and several different types of heat-pump systems
Advanced protection and control听strategies for thermal networks, SCADA and cybersecurity integration,听digital听twins听and performance monitoring.听

As a vendor-neutral service provider, our approach ensures clients receive technology-agnostic guidance focused on long-term performance and value.
Our district energy work is shaped by听innovation,听collaboration听and听real-world听delivery experience:听
- 30+ years听designing and modernizing DES听for听public and private听sector clients听worldwide.听More than听one billion square feet of built space, spread across multiple campuses, communities and facilities听are supported听through听integrated energy听planning.听听
- 180,000+ refrigeration tons of district heating and cooling capacity designed, installed or under construction.听
- More than听US$800听million听in听recent听energy projects听delivery.听听
- 5,000+ facilities improved through energy efficiency,听onsite听generation听and distributed energy solutions.听Across geographies and sectors, we support new and existing infrastructure. This helps听clients deliver systems that听perform today and听evolve听with the听demand,听policy听and technology听changes of tomorrow.听
