What We Do

What We Do

01 Row of large hot-water circulation pumps

Service 01

Thermal Infrastructure Transformation

We replace legacy steam with low-temperature hot water built for control, efficiency, and heat recovery. Rather than overlaying fixes, we reconfigure the thermal backbone to cut losses and support electrification.

  • Steam-to-LTHW conversion with full system engineering
  • 46 years of low-temperature hot water design expertise
  • Heat recovery integration across interconnected loads
  • Staged execution for continuously operating facilities

Service 02

Electrification & Heat Pumps

Electrification is a system design problem, not an equipment swap. We integrate heat pumps, heat recovery, and load balancing based on real operating conditions, enabling phased transitions that maintain uptime.

  • Heat pump selection and integration engineering
  • Load analysis before any equipment is specified
  • 6–10 COP chiller efficiencies we design for, not assume
  • Phased implementation that doesn't interrupt operations

03 Decarbonization master planning

Service 03

Decarbonization Master Planning

Structured, system-wide roadmaps aligned with your capital planning cycles. Heating, cooling, and process loads are evaluated together, with scenarios that balance cost, operational risk, and emissions.

  • Multi-scenario modeling tied to real capital cycles
  • Scope 1 & 2 pathways with defensible financial models
  • Alignment with utility incentives and policy frameworks
  • Clear phasing so leadership can commit with confidence

Service 04

Energy Efficiency (System-Level)

Improvements identified through detailed analysis of how energy flows across interconnected systems. Solutions are engineered holistically and validated through measured performance, not assumed savings.

  • Load modeling before any recommendation is made
  • System interactions modeled, not treated in isolation
  • M&V built into the project from day one
  • Validated results you can report to stakeholders

Service 05

Central Plant & Capital Planning

We help you use reinvestment cycles as a chance to rethink infrastructure. Plans prioritize lifecycle value, system integration, and scalability so investment supports long-term performance, not just near-term replacement.

  • Master planning tied to capital replacement schedules
  • Lifecycle cost modeling across competing scenarios
  • Integration with electrification and decarbonization plans
  • Peer-reviewed engineering, not sales-driven specs

06 LightNing lighting upgrades

Service 06

Lighting Upgrades (LightNing™)

Our low-voltage DC lighting systems reduce energy use, simplify maintenance, and enable advanced controls, designed for long-term reliability and integrated facility performance.

  • Low-voltage DC architecture for safety and efficiency
  • Significant reduction in energy and maintenance costs
  • Advanced controls and sensor integration
  • Designed for long-cycle replacement, not frequent service

Our methodology

How every WEI project works.

1

Analyze the Loads

We model every heat flow across your facility before touching any equipment specification.

2

Design the System

Engineering is done against real operating data, not catalog specs or rule-of-thumb assumptions.

3

Install & Commission

WEI engineers stay involved through installation and startup, not just the design phase.

4

Verify Performance

M&V is built into every project. We measure what we promised and report the actual results.
