Efficiency Technologies.
Once you’ve stopped the waste, the next question is: are you getting the most out of every unit of energy you consume? Efficiency technologies replace outdated equipment, add intelligent controls, and optimize how energy flows through a building — delivering more performance for less cost.
Smart Systems. Serious Savings.
Efficiency technologies are the bridge between conservation and generation. After you’ve sealed the envelope and reduced waste, efficiency upgrades ensure that every remaining unit of energy consumed delivers maximum output. Heat pumps replace inefficient HVAC. Smart controls eliminate unnecessary run time. Storage shifts when you use energy to when it costs least.
With 14 technologies in this pillar — from DC Nanogrids and Smart Breakers to EV Chargers and Whole House Fans — the Efficiency pillar has more tools than any other because smart energy use is where the biggest ongoing savings live.

Heat Pumps
Replace inefficient furnaces and AC units with a single system that heats and cools at 300% efficiency or better.
Explore →On-Demand Water Heaters
Eliminate standby heat loss entirely — hot water on demand, only when you need it, with no tank to maintain.
Explore →Home Smart Apps
Unified energy monitoring and control platforms that give homeowners and businesses real-time visibility and automation.
Explore →Soft Start Technology
Reduce motor startup surge current, extend equipment life, and lower demand charges — a simple upgrade with immediate impact.
Explore →Smart Breakers
Next-generation circuit breakers with real-time monitoring, remote control, and circuit-level energy data.
Explore →DC Nanogrids
Eliminate AC/DC conversion losses by distributing direct current locally — cutting energy waste in modern buildings and data environments.
Explore →Smart Thermostats
Learning thermostats and programmable controls that optimize HVAC run time — reducing energy use without sacrificing comfort.
Explore →Lighting Solutions
LED and advanced lighting systems cut lighting energy use by 50–75% with payback periods often under two years.
Explore →Laminar Flow Valves
Precision water flow control at the fixture — reducing hot water consumption and cutting both water and water-heating costs.
Explore →Storage
Battery storage systems that shift energy use to off-peak hours, back up critical loads, and maximize the value of on-site generation.
Explore →Air Handling Systems
High-efficiency air handling and ventilation systems that improve indoor air quality while reducing HVAC energy consumption.
Explore →Whole House Fans
Rapidly cool a home using outside air — dramatically reducing AC runtime during shoulder seasons at a fraction of the cost.
Explore →Attic Fans
Powered attic ventilation that exhausts trapped heat before it radiates into living spaces — reducing cooling loads significantly.
Explore →EV Chargers
Level 2 and smart EV charging solutions installed by certified partners — integrated into your home or facility energy system for maximum efficiency.
