Jefferson University Currents

  1. 1. CurrentsEnergy Management at Jefferson Jefferson’s Energy Strategy is to reduce energy costs and reduce energy use which will lower our carbon footprint. This article describes how we do this while delivering a world class patient experience. Energy Use at Jefferson First, how much energy do we use at Jefferson? Hospitals generally use energy as shown below: We are one of the largest energy users in the City of Philadelphia. We spend over $40 Million a year in energy costs (includes the cost for electricity, natural gas, steam, water and sewer services). We use over 260 Million kilowatt-hours (Kwh) of electricity every year.   To get a feel for just how much energy this is, consider your home: • Energy use for an “average” home in 2017 – 10,400 kilowatt-hours per year (U.S. Energy Information Administration) • Jefferson annual electricity use equivalent to 25,000 homes • Assuming 2.5 people in the “average” home (U.S. Department of Commerce, Economics and Statistics Administration), our electricity use each year is equivalent to approximately 62, 500 people • The population of Harrisburg is approximately 50,000. Therefore, Jefferson buildings use more electricity each year than all of the homes in the City of Harrisburg. The Energy Conser vation Newsletter • W I N T E R 2019 Vol.17,No.2 Welcome to our Jefferson Currents Newsletter. This newsletter will highlight our energy conservation efforts throughout the enterprise. The total energy spend for Jefferson is now more than $40 Million per year. The challenge – how do we manage this for maximum savings. The good news – we have a solid proven plan for doing this, as described in this newsletter. But we need your help. Every employee in every Department can help to reduce our energy costs. Please learn more... and take action!

  2. 2. Currents WINTER 2019 Jefferson monitors its energy use on a 24-hour basis throughout the Enterprise.    • Over 200 measuring points in all of our buildings • Real-time tracking of energy use on a 24/7 basis Jefferson’s Energy Management Team Jefferson is one of the few operating institutions in Philadelphia to have a dedicated full-time energy management professional. Jefferson’s energy management team members: • Randy Haines, Director of Energy Management • Facilities Operations Supervisors • Jefferson Controls Group • Facilities Design and Construction • Outside Contractors Randy has been in this position for over 22 years. Randy is a recognized leader in energy management in the City of Philadelphia. Randy served as the President of the Philadelphia Chapter of the Association of Energy Engineers (AEE), and later served as its International President. What does the Energy Management Department do? The Energy Services Department conducts the following day-to-day functions: • Energy Efficiency; management of energy efficiency projects (ESCO- AECOM), retrofit and new building energy designs, new technology research • Maintenance and Plant Operations; Continuous Commissioning (Cimetrics), Reliability Program, Co-Gen operation, employee training • Energy Metering; real-time tracking of energy use and characteristics for trouble-shooting and repairs • Energy Purchasing; purchasing, load shedding, market trend analysis • Energy Accounting; auditing, bill paying, tenant billing, energy budgeting • Reporting; management reports, energy team, energy benchmarking (City Rule), Currents Newsletter, awareness outreach. • Strategic Planning; policy and procedures, guides and standards, trend analyses Some Recent Results 1. Energy Purchasing • Newly signed electricity contract (until 2021) at a price that is lower than our current contract • 35% of our electricity is being supplied by a PA wind farm.   • East Falls has purchased renewable energy credits that are equivalent to them being 100% green. 2. Energy Efficiency projects • Co-generation units were installed at Abington (2012) and Torresdale (2016).  The Torresdale unit saves $360,000/year • Long-term energy efficiency projects conducted in Center City over the last 18 years are now saving over $4.4 M/year in energy costs • Installation of a new software system by Cimetris Inc. to perform continuous commissioning of our energy using equipment (see article below) • Replacing over 85,000 lamps (bulbs) with higher efficiency LED products and also adding over 3000 new occupancy sensors 3. Load Shedding • Voluntary program for the electrical “grid” that we are in • Financially rewards companies that can reduce their energy use when needed by the grid…we have developed a plan to do this, safely   • We receive payments each year for our participation YOUR Role in Jefferson’s Energy Management Plan Energy management and conservation at Jefferson has two parts: 1. What the Enterprise does to conserve energy, described above 2. What YOU can do to conserve energy You may not realize how important individual employee energy conservation is to Jefferson.  We would like to ask everyone to practice the following energy saving steps in your everyday job: 1. Turn out lights when not needed in public spaces such as conference or break rooms 2. Close fume hoods when not in use 3. Turn off unused vacuum lines 4. Call in water leaks to 5-6846 for leak maintenance Energy Management at Jefferson – continued
  3. 3. Jefferson’s Building Commissioning Project What is Building Commissioning? • checking and testing (“tune-up”) your building’s energy- using equipment during design, construction and turnover to the building owner. What is Continuous Commissioning? • checking and testing your equipment continuously, 24/7. while it is operating.  Buildings change, all the time, in many ways. Interior spaces and uses can change. Equipment wears down with age and is oftentimes changed in piecemeal fashion. Active buildings like ours change quickly.  Continuous commissioning helps us know that our buildings are changing in a way that won’t waste energy, while increasing occupant comfort at the same time. Jefferson’s Continuous Commissioning Program The Jefferson continuous commissioning program began in March of 2013. We selected the following team of recognized experts in continuous commissioning for the project: Cimetrics Inc. • 30-year old Boston-based company that is a leader in analytics technology for building automation systems • Recognized leader in continuous commissioning using their Analytika software, which is now being used by Jefferson. Martinez Cx • A Philadelphia commissioning company that coordinates the Cimetrics project for us.   • Alex Martinez, the owner of this company, has worked locally in facilities maintenance and management for over 20 years and has done commissioning work for the past 10 years.  How Does the Jefferson Continuous Commissioning Program Work? Before Cimetrics, it was difficult for us to identify building energy problems because they can easily be “hidden”, such as heating and cooling an area at the same time. The Cimetrics program overcomes this with sophisticated technology developed by Cimetrics. • The Cimetrics Anaylika software has now been added to our Siemens building automation system to help identify and target energy-wasting issues. • The Cimetrics Analytica process not only helps us find existing energy wasting problems with our equipment, it can also “predict” a problem and can identify where a problem exists but is “hiding”. Currents WINTER 2019 L to R, Lisa Zagura, Senior Analyst, Cimetrics, Alex Martinez, Martinez Cx, Randy Haines, Jefferson Director of Energy Management, and Mary Ellen Cantabene, Cimetrics COO discuss the progress and results of the program at an office meeting. Bob Pizzo, Facilities Services Control Technician and Alex Martinez field verify problem areas targeted by Cimetrics.
  4. 4. Currents WINTER 2019 The Cimetrics program includes: • The analysis of 18 Center City buildings that have a combined floor space of almost 4 Million square feet. • The Cimetrics software analyzes over 76,000 system operation sampling points in our Siemens Apogee Building Automation System, (BAS).   • Over 1.2 Million sampling points are evaluated by the Cimetrics system every day. These sampling points are in: • 20 Chillers and 4 cooling towers • 116 pumps • 247 air handling units • 100 fume hoods in 200+ lab areas • 41 operating rooms • 4,300 exhaust fans The Cimetrics workflow is a two-part process: 1. Cimetrics Analytika software: • Determines where a mechanical and control system fault is occurring that can result in unusual energy use • Identifies a corrective action for the situation and also identifies cost factors for the potential problem • Documents the incident and sends this to Martinez Cx for field verification 2. Martinez Cx and a Jefferson Facilities supervisor • visit the problem condition or area  to confirm or deny the problem condition. • If confirmed by Martinez Cx, Jefferson Facilities personnel correct the problem using the Facilities Department’s work order process. The final step in the Cimetrics process is a follow-up evaluation of the repair or correction. What Have Been the Cimetrics Results So Far? The Cimetrics program results so far have been: • Energy cost savings of over $1 Million dollars. • The reduction in CO2 from our reduced energy use is over 7,000 Metric Tons. This is the equivalent of taking 1500 cars off the road for a year. Jefferson continues to sustainably provide its world class patient experience every day. Bob Pizzo and Alex Martinez do extensive field checking and verification of potential energy-using problems with our equipment on a regular basis.
  5. 5. Home Heating Tips for Winter Heating your home: • uses more energy and costs more money than any other system in your home • typically makes up about 42% of your utility bill. • No matter what kind of heating system you have in your house, you can save money and increase your comfort by properly maintaining and upgrading your equipment. Using a “whole house” plan can save about 30% on your energy bill while reducing environmental emissions. Here’s some tips for saving home heating energy costs this year: • Upgrade ceiling insulation to R-38 (higher R values mean greater insulation levels and thus more energy savings) • Insulate exterior heated basement walls to at least R-11. • Set your home thermostat as low as comfortable (68 F is suggested) when the house is occupied. • Set back the thermostat by about 8 degrees at night or when the house is unoccupied during the day. • Set back the thermostat to 50 to 55 F when the house is unoccupied for over 24 hours. • Install a programmable thermostat to automatically provide the setbacks mentioned above • Replace furnace filters once a month during the heating season. • Remove any obstructions and clean heating registers regularly. • During winter, keep the draperies and shades on your south-facing windows open during the day to allow the sunlight to enter your home and closed at night to reduce the chill you may feel from cold windows. And if you replace your heating system, remember that you may be able to get a PECO rebate to help with the costs.
