How Steam to Hot Water Conversion and Other Transformational Changes Lead the Way. University campuses across North America are pursuing ambitious plans for sustainable energy supply, motivated by a desire not just to lower costs but also to achieve meaningful reductions in greenhouse gas emissions. After capturing “low-hanging fruit,” such as lighting upgrades, many are seeking deeper, transformational energy retrofits, including steam to hot water conversion, electrification of heating, heat recovery technologies, and renewables. These changes were the subject of a roundtable discussion hosted by Ecosystem Energy Services at the APPA conference in San Francisco this July.
A double win for Ecosystem! Our projects at CAE and the Quebec City University Hospital Center (CHU) both received 2017 Energia awards. Recognizing best practices and excellence in energy efficiency, the Energia awards are conferred by AQME, Quebec’s association for energy management.
In this short video, Robert Shipley, Associate Vice President of Facilities at Adelphi University, shares his experience balancing a large retrofit project with construction of a new campus building, and describes the challenges of fitting modern technology into a space built in the mid-1900’s. The results of some smart engineering in 2016 are generating significant savings in 2017, giving Bob just a little bit more to work with as he faces his next set of challenges.
We all strive to do more with less to improve our schools’ learning environments and to keep abreast of commitments to a sustainable future. In this short video, Timothy Burton, Senior Vice President of Finance at Adelphi University shares his best practices for financing an energy savings project and how to avoid a common pitfall when working with ESCOs. By analyzing different offers, Tim was able to turn a large project with 15-year payback to one that starts generating savings for Adelphi in year eight and is cash-neutral almost from day one.
Mineola School District is using the IEPC approach to convert the steam distribution networks at Hampton Street School, Jackson Avenue School, and the Middle School to hot water networks. This is the first steam-to-hot-water (STHW) conversion project in a NYS school district through an EPC. A hot water network can perform the same heating functions as a steam network but is significantly more efficient and easier to control. Dr. Michael Nagler, Superintendent at Mineola Public Schools, spoke exclusively to Ecosystem’s Ahmed Ibrahim about this groundbreaking project.
Since last summer, the Patriotes School Board and Ecosystem have been collaborating to reduce the school board’s energy use and greenhouse gas emissions by upgrading 26 schools. The project will decrease energy bills by 39%, generating $960,000 in annual savings. Greenhouse emissions will drop by 2,455 metric tons of CO2 per year, the equivalent of removing 1091 cars from the road. As part of this project, Mont-Bruno Secondary School will benefit from an innovative energy efficiency measure. Due to its strategic location near Goyer Lake, it will become one of the few schools in Quebec to use an open-loop geothermal system to meet its energy needs.
Residents at 710 and 720 Trethewey Drive in Toronto, Canada, can now enjoy more fresh air and better heating in their buildings, thanks to the recent installations of new condensing boilers and air handling units. This work is part of the TowerWise Retrofit project, funded by The Atmospheric Fund, which will upgrade seven Toronto Community Housing buildings, currently home to over 1,200 residents. The project aims to reduce energy consumption by 20%.
Since 1994, engineering students from the ETS university in Montreal have participated in an international cooperation program called PRECI (Programme de Regroupement Étudiant pour la Coopération Internationale). Each year, a team of ETS students design and build an engineering project in a developing country.
An energy efficiency project is underway at the Olympic Park which will reduce operating costs by $1.3M per year and greenhouse gas emissions by 57%. The Olympic Park’s electromechanical systems are undergoing major upgrades with the goal of dramatically reducing energy bills, eliminating energy waste, and optimizing systems so they meet real needs without overconsuming.
It’s almost the most wonderful time of the year, with the kids looking forward to receiving presents and being out of school. If you are a facility operator or a controls technician for a school board, however, you probably are planning the best way to shut down the schools’ building automation system (BAS) during the two-week period. We asked our resident BAS experts for their advice, and here is the checklist of how to prepare the shut-down.
