Energy Optimization
BAS Energy Optimization Strategies by Nexklima Inc.
A Building Automation System delivers its greatest return on investment when tuned for proactive energy optimization. Nexklima Inc. writes and deploys dynamic software algorithms that reduce electric and natural gas consumption without sacrificing occupant thermal comfort or indoor air quality.
By leveraging advanced control routines, your building automatically responds to weather shifts, occupancy fluctuations, and utility peak-demand pricing.
Dynamic Energy Saving Algorithms
Demand-Controlled Ventilation (DCV)
Standard building codes often mandate static outdoor air ventilation based on peak occupancy assumptions, leading to massive energy waste from conditioning unneeded outdoor air.
- Integration of real-time carbon dioxide ($CO_2$) sensors across return air streams and high-occupancy zones
- Automated modulation of outdoor air intake dampers to supply fresh air only when occupancy levels demand it
- Significant reduction in baseline heating and cooling load during low-occupancy hours
Automated System Resets
Static operating setpoints force mechanical plants to run at maximum output even under light thermal building loads.
- Supply Air Temperature Reset: Automatically raising supply air temperatures when cooling demand drops across all zones.
- Duct Static Pressure Reset: Trimming variable frequency drive (VFD) fan speeds based on real-time zone damper positions.
- Chilled & Hot Water Reset: Dynamically adjusting water loop temperatures according to outdoor ambient air conditions.
Peak Load Shedding & Demand Management
Utility companies charge significant demand penalties when commercial facilities spike their electrical draw during peak grid hours.
- Automated power tracking integrated with utility smart meters
- Algorithmic load-shedding sequences that temporarily adjust non-critical space temperatures, dim lighting, or stage down chillers
- Substantial reductions in monthly utility demand charges ($/kW$)
Estimated Energy Savings Potential
Standard Operation ──► Static Setpoints & Fixed Schedules ──► Baseline Utility Cost
Optimized BAS ──► DCV + Resets + Demand Shedding ──► 15% to 30% Annual Reduction
- Demand-Controlled Ventilation: Up to 20% reduction in heating/cooling energy.
- Variable Speed & Pressure Resets: 10% to 15% reduction in fan and pump electrical draw.
- Peak Load Shedding: 10% to 25% reduction in monthly utility demand penalties.
Frequently Asked Questions
Will energy optimization strategies make my building uncomfortably warm or cold?
No. All optimization sequences programmed by Nexklima Inc. operate within strict, pre-approved comfort boundaries. The system makes tiny, incremental setpoint adjustments that reduce energy use while keeping space conditions within target comfort zones.
