Multi-Site Industrial Portfolio — Midwest, USA

CHALLENGE

A private equity-backed industrial operator with 14 facilities across the Midwest had no visibility into facility-level energy consumption. Energy costs were running at approximately 12% of revenue well above the industry benchmark. The firm was preparing for a sale process and wanted to improve EBITDA before going to market.

SOLUTION

Lumen conducted a portfolio-wide energy audit across all 14 sites within 60 days. LumenSmart™ monitoring was deployed at the six highest-consumption facilities. Mechanical optimization was implemented at four sites with compressed air system inefficiencies. LED conversion was completed at all facilities. Electricity procurement renegotiation reduced the blended rate across the portfolio.

RESULTS

  • 22% reduction in total energy consumption across the portfolio
  • $1.4M in annualized cost savings
  • EBITDA improved by $1.4M, supporting a significantly higher exit multiple
  • Carbon output reduced by an estimated 1,800 metric tons CO₂e annually
  • Project completed within 90 days of engagement

Class A Office Tower — London, UK

CHALLENGE

A London commercial property owner was facing rising energy costs at a 250,000 sq ft Class A office building. Utility costs had increased 30% over two years due to market pricing changes and aging building systems. The building’s energy intensity was affecting its BREEAM rating and tenant retention conversations.

SOLUTION

Lumen UK conducted a full building energy audit and identified three primary opportunity areas: HVAC controls optimization, lighting upgrades to smart LED, and a renegotiated energy supply contract. LumenSmart™ was installed to provide real-time baseline data and ongoing monitoring.

RESULTS

  • 29% reduction in electricity consumption in the first year
  • £420,000 in annual cost savings
  • BREEAM energy rating improved from ‘Good’ to ‘Very Good’
  • LED conversion completed with 14-month payback
  • Tenant retention improved — energy performance cited in lease renewals

Hotel Portfolio — Eastern US

CHALLENGE

A hospitality operator managing 8 full-service hotels was experiencing energy costs as a percentage of revenue well above their peer group. Management-level visibility into property-level consumption was limited, making it difficult to benchmark performance or prioritize capital allocation.

SOLUTION

Lumen deployed LumenSmart™ across all 8 properties to establish consumption baselines by department (rooms, F&B, back-of-house, common areas). HVAC scheduling was recalibrated property by property. LED conversion was completed in all high-use areas. Electricity contracts were renegotiated for the full portfolio in a single procurement event.

RESULTS

  • Average 24% reduction in energy costs per property
  • $2.1M in total annualized savings across the portfolio
  • Energy cost as % of revenue reduced from 9.1% to 6.9%
  • Full portfolio deployment completed within 120 days
  • Ongoing LumenSmart™ monitoring maintains savings and flags new opportunities

Multi-Family Residential Portfolio — Southeast US

CHALLENGE

A real estate investment trust managing 22 multi-family properties needed to reduce common-area energy costs to improve NOI across its portfolio. Individual property managers had limited tools to manage energy consumption and no visibility across sites.

SOLUTION

Lumen audited the top 10 highest-cost properties and implemented LED conversion in all common areas, parking structures, and corridors. LumenSmart™ monitoring was installed in shared mechanical rooms. HVAC optimization was applied to buildings with centralized systems.

RESULTS

  • 34% reduction in common-area energy costs
  • $680,000 in annualized savings across the 10-property initial rollout
  • Expanded to all 22 properties in Phase 2 based on Phase 1 results
  • Total portfolio savings estimated at $1.5M annually on full deployment
  • NOI improved meaningfully across the portfolio; asset valuations increased
