A 1970s bungalow experienced high heating bills and uneven comfort. We performed a whole-house audit that identified air leakage, under-insulated walls, and an aging HVAC system. The solution combined attic and cavity insulation, targeted air sealing, high-efficiency heat pump replacement, and a programmable smart thermostat tied to occupancy patterns. Post-install monitoring over 12 months showed a 28 percent reduction in site energy use, reduced peak demand in winter, and improved overnight comfort. The owner benefited from available state rebates for heat pump installation, shortening payback to under six years.
Project portfolio
Our portfolio highlights practical projects where focused energy measures produced measurable results. Each project begins with a baseline energy assessment to identify the highest impact opportunities. We then apply a combination of targeted retrofits, efficient equipment selection, and smarter controls to improve thermal integrity, reduce wasted energy, and manage peak demand. Typical interventions include insulation and air sealing, efficient HVAC replacements, ENERGY STAR appliance swaps, smart thermostats, submetering, and solar plus battery integration. Where applicable, we implement continuous monitoring and verification so clients can see actual savings over time. The case studies below represent residential, commercial, and industrial work spanning small home retrofits to multi-site commercial rollouts, all emphasizing safety, documented performance, and occupant comfort.
Featured case studies
We select representative projects that demonstrate our process from audit through verification. Each case focuses on measurable outcomes and replicable steps so other property owners can learn from real implementations. Below are condensed descriptions outlining the challenge, the solution, and verified results after commissioning and monitoring. These summaries include context on incentives or financing where relevant and highlight occupant benefits like improved thermal comfort and reduced system noise.
A mid-sized office building needed to reduce demand charges while improving tenant comfort. We designed a rooftop PV array sized for midday loads and integrated it with an energy management system controlling HVAC setpoints and scheduled equipment. The building automation system adjusted ventilation and temperature setpoints during peak price periods, using solar generation and battery buffering to shave demand peaks. Over the first year, demand charges dropped significantly and daytime solar self-consumption reached a favorable level. Tenants reported more stable temperatures and reduced HVAC cycling noise after controls tuning.
A mid-sized manufacturing line had inefficient heat recovery and inconsistent motor controls. After an audit and data collection phase, we implemented heat exchanger retrofits, variable speed drives for motors, and analytics-based scheduling to align production with lower cost grid hours. A monitoring layer tracked energy intensity by product lot, enabling operators to identify waste and eliminate idle runs. The plant achieved a notable reduction in energy intensity, with measured savings that supported a short-term capital recovery plan. The project also improved process stability and reduced maintenance disruptions.
Approach to measurement and verification
Measurement and verification is central to our portfolio work so clients can trust reported results. We begin by establishing a clear baseline using utility data, on-site metering, and, when necessary, short-duration submetering to isolate major end uses. Baselines account for weather and occupancy to ensure apples-to-apples comparisons. After implementing measures, we deploy monitoring equipment and dashboards that summarize energy, demand, and comfort metrics. Our M and V plans follow recognized frameworks that enable incentive qualification and provide confidence in persistence of savings. Where ongoing optimization is valuable, we maintain a monitoring contract to tune controls, detect drift, and recommend low-cost operational adjustments. This emphasis on verification turns projects from one-time capital works into lasting performance improvements that continue to pay back over time.
