Finding and Mining Today’s Energy Inefficiencies The Gold Rush of the 21st Century Lorenz V. Schoff Energy Consultant “Finding Little Energy Inefficiencies, Generating Big Energy Savings”
Background Information 43+ years in Facilities Management AF Civil Engineering Officer Director of Facilities for Governmental Agency Original member of US DOE – Rebuild America Member of Committees working on Design Documents for ASHRAE and USGBC
Background Information – Commercial Bldg 18% of all energy use in the US – $100 Billion + Cooking 2%; Computers 3%; Electronics 6%; Ventilation 6%; Water Heating 6%; Refrigeration 6%; Lighting 30%; Space Heating 17%; Space Cooling 14% 4.9 Million Buildings 72 Billion SF Average site Energy Intensity – 91 kBtu’s/SF/Yr Average Primary Energy Intensity – 191 kBtu’s/SF/Yr
Agenda Observations How buildings are Operated? What is Energy Management (EM)? Best Practices in Operations, Maintenance and Behavior Bottom-Line
Observations Limited or Reduced Maintenance Improper Light Levels Energy Inefficient Equipment To Many Personal Appliances Improper Use of Controls
Observations Limited or Reduced Maintenance Dirty Filters increase energy use (EU) Cleaning of light lenses reduce light levels Increased friction increase EU Leaks around doors and windows increase EU
Observations Improper Light Levels Office areas over illuminated Hallways over illuminated Storage and Mechanical Areas Use of shades and blinds
Observations Energy Inefficient Equipment HVAC Equipment Motors Appliances
Observations To Many Personal Appliances Personal Heaters Refrigerators Microwave Ovens Fans
Observations Improper Use of Controls Light Switches Thermostats Energy Management Systems
How Buildings are Operated? Without knowledge of energy use and impact of individuals actions Lack of Utility Management No Energy Policy/Regulation No approved Energy Management Plan
How Buildings are Operated? Education is Key to the Success of Any Program -- Energy Awareness of all `
How Buildings are Operated? Lack of Utility Management No Knowledge of how much energy is used Can not Manage what you do not know
How Buildings are Operated? No Energy Policy/Regulation No approved Energy Management Plan
What is Energy Management? A process to obtain an Understanding of: Building Utilization How energy is being consumed Energy Systems Installed A process to: Improve overall energy efficiency and reduce impact on the environment
What is Energy Management? Understanding of Building Utilization What areas are used and when? Patterns of occupancy and habits Space compatible with programs and energy efficiency How’s the Energy is being consumed? What are the light levels? Identifying Plug and Phantom Loads HVAC equipment operations – EMCS Electrical Systems
Adoption of an “Energy Policy” KISS Principle “… provide leadership in developing a realistic energy ethic in the operation of its facilities and reduce operating costs…” “… success …Is the Joint responsibility of the administrators and employees is based on their cooperation.” Development a Successful EM Program
Gather the Energy Utility Data Use this data to establish a baseline – kBtu’s/SF/YR Establish Baseline Portfolio Manager will assist in validation of Efforts Sub-metering of circuits helpful Who reviews this information/data? Data, Info, Baseline
Conduct an Energy Use Audit of Each Facility Determine Building Occupancy Profiles Determine Building Characteristics and Systems Conduct an Plug Load Survey Remember you can not determine how much you can save until you know how much you use Data, Info, Baseline
EM Regulation Operation of energy systems in the building Establish accountability for action in each building Establish method for Baseline Energy Use in each Bldg Establish an Energy Management Teams Describe an Incentive Program Establish a reporting and evaluation methodology EM Plan Designate Responsibility and means of implementation Establish goals and objectives Establish Checklist for all personnel Establish an Energy Awareness Training program for all personnel Establish a means of evaluating and celebrating success Other EM Elements
Plug and Phantom Loads What is a plug load? How best to control plug loads? What is a Phantom load? Means of controlling Phantom Loads?
It’s the Little Things Turning off Lights Offices Storage All Areas Control of Plug Loads and Phantom Loads Cleaning Operations Use of Facilities Best Practices in Operations, Maintenance and Behavior
Energy Awareness Training All Personnel KISS Newsletters Make it part of daily routine They can be part of the solution or part of the problem Best Practices in Operations, Maintenance and Behavior
Potential Energy Savings • Use of Lighting Systems – 15% • Lighting Controls – 10% • Energy Awareness Training 10-15%
It’s Not Rocket Science Nothing is Impossible it just takes time and resolve
