OUS Capital developed the Energy Savings-as-a-Service platform to implement carbon reduction and energy saving equipment onsite, along with the Decarbonization Energy Fund, to provide the capital to offer energy and carbon Savings-as-a-Service including equipment maintenance. OUS Capital simply charges a monthly service fee that is less than what a building is currently spending.


Chillers nationwide use 20% of the electricity iny USA. The Department of Energyf least 30% of thisf


the (DOE) estimates that at electricity is wasted because the chillers


and chilled water system are not properly optimized. One condominium association with a fixed speed compressor was recently converted to a variable speed through the installation of af


variable frequency drive (VFD) and an


advanced controller. Chillers are designed for the several hottest days in a year. Chillers run most efficiently when they are fully loaded so a fixed speed compressor is inefficient most of thef


ally year. By converting the chiller to


a variable speed, it can achieve huge energy savings by reducing the frequency to match the actual load for cooling. Through the Smart Compressor Controller, savings typically are at the 40% energy savings level as well as extending tg the life of thef


536,230 kWh per year creating $48,536 in annual savings. The Energy Savings-as-a-Service 60-month service fee was $3,212 leaving over $800 in net cash savings a month. After

water. In fact, water has an embedded carbon footprint from using 4% of all the electricity used in the USA for pumping, water, and sewer. One condo association thought its water sewer bills were getting excessive. We utilized ultrasonic meter to identify the fact that every minute of the day at least 8-gallons was flowing. That means is a leak, and 8-gallons per minute is 3,153,600 gallons per year or $31,536 in cost. The property had been built in the 1970s using 3.5 gallon-per-flush toilets. Our solution

Going solar is not practical for the majority of mid and high-rise community associations but HOAs (homeowners associations) with extra property cany


be


a good fit. Designing and engineering a solar systemis the first step, along with preliminary energy modeling. Solar in Illinois requires an association to submit and get qualified for SRECs (Solar Renewable Energy Credits) to enhance the economic viability since electric rates are still low. Then an interconnect study is done by ComEd (Commonwealth Edison). We are currently beginning a project for 527 kWh at an HOA that would generate 743,493 kWh per year. Over a 20-year Solar Savings-as-a-Service agreement, the HOA would have a net savings of $458,436 and have saved 26,170,000 pounds of carbonf


dioxide from being produced.
