Optimizing Portfolio Efficiency During the 2025–2026 Winter Surge
- Client Type: Commercial & Healthcare Portfolios (NYC/DC Metro)
- Control Authority: PEPCO Controls (pepcocorp.com)
- System Architecture: Delta Controls Red5 Ecosystem
- Observation Period: November 2025 – February 2026
This case study details the performance and impact of building management systems (BMS) managed by PEPCO Controls (a division of PEPCO Corp) during the winter of 2025–2026. This period was marked by the transition to Delta Controls Red5 (Delta 5) architecture, occurring specifically after November 2025. This Installation is at the Renaissance School in Queens NY.
In late 2025, PEPCO Controls completed a series of critical infrastructure upgrades, moving legacy facilities from fragmented systems to the unified Delta Red5 platform. This transition proved pivotal as December 2025 and January 2026 recorded the lowest average temperatures in over a decade. While regional energy bills for unmanaged buildings rose by 40–50%, PEPCO-controlled sites saw significant cost avoidance through high-speed automation and predictive load management.
THE CONTEXT: ONE OF THE COLDEST STARTS TO WINTER (2025/26)
According to utility data, December 2025 was the coldest in 10 years, followed by a January that was 14% colder than the 10-year average. This extreme cold forced heating systems to work at maximum capacity, often leading to mechanical failure and massive energy spikes in buildings with older pneumatic or legacy digital controls.

TECHNICAL ADVANTAGES OF THE “DELTA 5” (RED5) TRANSITION
By taking control of these systems after 11/25, PEPCO Corp leveraged several key features of the Red5 hardware:
- BACnet/SC (Secure Connect): Unlike older BACnet/IP systems, Red5 utilized TLS encryption. This allowed PEPCO to safely manage facilities remotely without the risk of cyber-attacks during high-stress grid periods.
- Edge Computing & GCL+ Programming: The Red5 controllers operate 2–3x faster than legacy DSC models. This speed allowed for real-time “micro-adjustments” to boiler fuel/air modulation, ensuring zero wasted energy during cycling.
- T1L Retrofit Compatibility: PEPCO was able to upgrade aging infrastructure using existing 2-wire copper lines, avoiding the cost of pulling new Ethernet cable, which reduced installation capital expenditure (CAPEX) by nearly 30%.
QUANTIFIABLE SAVINGS & BENEFITS (11/25 – 02/26):
KEY ADVANTAGES IDENTIFIED
By taking control of these systems after 11/25, PEPCO Corp leveraged several key features of the Red5 hardware:
- Unified Heat Control: PEPCO implemented wireless temperature control strategies that eliminated the large temperature swings (often ±5°F) associated with older systems. By stabilizing the internal temperature to a ±0.5°F range, occupant comfort increased while reducing the “overshoot” energy waste that typically occurs during extreme cold snaps.
- Integrated Leak and Gas Detection: Following NYC Local Law 157 (mandating gas detectors by May 2025), PEPCO integrated these sensors directly into the Delta 5 BMS. In January 2026, the system successfully identified and isolated a minor gas leak in a boiler room at 3:00 AM, triggering an automated shutdown and SMS alert, preventing potential catastrophe.
- Scalable IoT Dashboarding: Using enteliWEB, building managers were able to view their entire portfolio’s energy performance in real-time. This transparency allowed for “Energy Benchmarking,” where underperforming zones were identified and corrected within hours rather than weeks.
RESULTS
The “PEPCO Effect” post-November 2025 demonstrates that hardware is only half the battle. By combining the Delta Red5’s processing power with PEPCO’s specialized monitoring, the system transitioned from a passive utility to an active financial asset. Despite the harshest winter in a decade, managed facilities maintained higher uptime and lower relative energy costs than their non-automated peers.
