1 Energy and Water Benchmarking for Hospitals March 22, 2016 Presented by Dan Doyle, P.E., LEED AP Chairman, Grumman/Butkus Associates Grumman/Butkus Associates Energy Consultants and Design Engineers

2 Presenter Dan Doyle is the Chairman of Grumman/Butkus Associates, a firm of energy efficiency consultants and sustainable design engineers. In this role, he is responsible for the firm's marketing and recruiting. He is also the principal-in-charge for numerous designs and studies. For the past 35 years, Dan's career has focused on energy conservation and efficiency improvements in new and existing buildings, especially energy-intensive and mission critical facilities, such as laboratories, hospitals, data centers, and specialized manufacturing facilities. Dan is a frequent public speaker on sustainability topics and is active in multiple professional associations. 2

3 Learning Objectives Gain an understanding of what benchmarking tools are available for healthcare facilities. Learn results of an annual healthcare facilities benchmarking survey encompassing more than 100 healthcare sites, including both energy and water use. Examine typical resource usage patterns for healthcare facilities. Learn how benchmarking can be the first step in establishing a comprehensive energy and water management program for your hospital. 3

4 Why Should We Care About Conserving Energy and Water in Hospitals? 4

5 Why Should We Care About Conserving Energy and Water in Hospitals? 5

6 Hospitals Are Energy-Intensive Facilities Challenge: Hospitals use two to three times more energy (per sq. ft.) than office buildings 24/7/365 occupancy Demands for high airflow, filtration Lots of energy-consuming equipment (MRIs, PET scans, etc.) 6

7 Hospitals Are Energy-Intensive Facilities EPA estimates that the U.S. healthcare sector s current annual electricity use of 73 trillion kilowatt-hours (kwh) contributes $600 million per year to healthcare costs via increased asthma and other respiratory illness. Reducing energy usage reduces a hospital s operational costs and reduces a hospital s carbon footprint 7

8 ASHE Benchmarking Data: Cost Breakdown of Facility Budgets Energy represents more than half of the healthcare facility budget, according to current benchmarking data from the American Society for Healthcare Engineering. That s more than staffing, materials, and service contracts combined. 8

9 Hospitals Are Energy-Intensive Facilities Opportunity: $100,000 reduction in energy costs is equivalent to $2 million in new revenues (assumes 5% ROS) Research by the EPA shows that hospitals that implement energy conservation measures (ECMs) outperform competing hospitals by as much as 10% in net operating income EPA Study, Boosting Your Bottom Line Through Improved Energy Use, June

10 So Where Do We Start This Process? Benchmarking! 10

11 Why Benchmark Energy Use? Is 10 MPG high or low for an automobile? Is 350 kbtu/sf/yr high or low for a hospital? Answer: Common knowledge Answer:??? 11

12 The Benchmarking Process Only a screening tool Doesn t explain why a building performs a certain way or how to change its performance (we ll get to that later) 12

13 The Benchmarking Process Use benchmarking results to initiate action plans Benchmarking only begins the improvement process If nothing else changes, don t expect your future performance to improve 13

14 EPA s ENERGY STAR A rating scale of 0 to 100 A rating of 50 indicates average performance A rating of 75 or above indicates top performance Eligible for an ENERGY STAR label Most well-known, widely accepted benchmarking and rating system 14

15 EPA s ENERGY STAR Hospitals are not compared to others entered into Portfolio Manager to determine score Until recently, used database from a 1996 EPRI Study New database from EPA/ASHE incorporated in Fall hospitals Average hospital size: 448,061 sq ft Average source energy intensity: 485 kbtu/sq ft Equivalent site energy intensity: 252 kbtu/sq ft The switch to the new database caused changes to most scores 15

16 Energy Benchmarking What else is available for hospitals? Practice Greenhealth s Sustainability Benchmarking Report G/BA s Energy and Water Benchmarking Survey ASHRAE beq limited adoption, has future potential for operational and as-built ratings Green Globes for Existing Buildings DOE Benchmark Buildings Municipal reporting (NYC, Chicago, Boston, etc.) 16

17 Practice Greenhealth Sustainability Benchmark Report Compilation of metrics from 220 hospitals that submitted entries to 2015 Partner for Change awards program Provides best practice metrics for energy, water, waste from the top performers Good data for goal setting Member benefit PGHBenchmarkingReport 17

31 G/BA Benchmarking Survey Natural Gas and Electricity Cost Trends for Hospitals,

32 Don t Forget the Water! Water and energy are inextricably linked: The treatment and delivery of water accounts for as much as 15% of energy consumption in many other parts of the country Energy represents 80% of a typical water bill Power plants use lots of fresh water (38% of nationwide total), and half of that evaporates By increasing efficiency through water conservation and recycling practices, your hospital can further cut its energy consumption and thus its carbon footprint Reducing water consumption will also reduce sewer charges 32

39 MHA Benchmarking Survey How can we help MHA develop an exclusive energy and water survey for MHA members? 39

40 Benchmarking Survey Survey questions from 2015 (2014 data) G/BA is now collecting data through an on-line tool 40

41 How Can You Use the Benchmarking Process To Improve Your Performance? Comprehensive Approach: Utility tracking Benchmarking Energy purchases/ supply-side management Operations and maintenance Retro-commissioning (RCx) Retrofit of existing building systems/equipment Building infrastructure planning New buildings, major additions & renovations Commissioning and monitoringbased commissioning (Cx, MBCx) Equipment purchasing policies Grants and rebate opportunities Recognition opportunities Financing options 41
