8 The National Challenge Eliminate Energy Waste Energy waste at work and at home will cost U.S. organizations and consumers billions of dollars in the next 10 years. Wasted energy contributes to smog, acid rain, and greenhouse gas emissions.

9 ENERGY STAR K-12 Schools Maximizing Indoor Environmental Quality with ENERGY STAR

10 Be a Leader Change Our Environment for the Better U.S. EPA s ENERGY STAR The U.S. Environmental Protection Agency (EPA) can help you with buildings and plants to: Reduce energy waste Reduce GHG emissions Protect the environment Learn more and become an ENERGY STAR partner at

11 What is ENERGY STAR? A government-backed, voluntary program that helps businesses and individuals protect the environment through superior energy performance by providing energy efficient solutions for homes, businesses, and institutions. The national symbol for environmental protection through energy efficiency, recognized by more than 65% of all U.S. households.

12 Maximizing Indoor Environmental Quality with ENERGY STAR

13 Let s Get Together Savings of 40-45% possible with energy saving actions compatible with IEQ Energy Cost and IAQ Performance of Ventilation Systems and Controls

14 IAQ is a Health Risk 90% of most peoples time is spent indoors Pollutant levels indoors are often higher than outdoors Ranked in top 3 environmental health risks by EPA s Science Advisory Board

15 Why Incorporate IEQ? Improves health, comfort, and performance of students / staff Documented health and performance benefits Reduced absences ($) Improved student performance ($) Improved perceptions and lower turnover ($) Reduced liability ($) Needed for ENERGY STAR Building label

16 Overview: Key Factors Energy Efficiency Outdoor Climate Building envelope HVAC Outdoor Air (OA) ventilation requirements T-RH setpoints Equipment sizing Equipment efficiencies Equipment, energy performance and operating controls Lighting loads Other loads IEQ Outdoor climate and pollution Building envelope HVAC OA ventilation rate needs Occupant needs for T-RH Sufficient equipment capacity Reliable functional performance Lighting quality Indoor pollution source loads

17 What To Do Actions to Protect or Enhance IEQ

18 Prescriptive vs. Performance Technology Performance 60% fan systems oversized by 60% Chillers oversized 50% to 200% Improper installation and poor maintenance Buildings can exceed code and not perform as intended

19 Actions Compatible with IEQ Efficient fans, motors, drives: OK Efficient chillers/boilers: OK Reduce lighting/office equipment use at night: OK Energy recovery: Good Preventive Maintenance: Good Commissioning controls & equipment: Good OK = Reduces energy with no impact on IEQ or where IEQ can easily be protected Good = Reduces energy and could improve IEQ

20 Actions Compatible With IEQ With Cautions Air-side economizer: Good - Watch Relative Humidity (RH) and polluted outdoor air Building shell: OK - Watch infiltration rate and adjust OA supply accordingly-all HVAC systems Reduce internal loads: OK - Avoid non ENERGY STAR qualified upgrades to protect against inadequate lighting quality - Recalibrate OA control under VAV systems Equipment Downsizing: OK - Watch peak load -- use with Energy Recovery

21 IAQ Resources IAQ Tools for Schools & IAQ Design Tools for Schools IAQ Building Education and Assessment Model (I-BEAM) buildings

22 Tools & Resources Energy Efficient New Construction Use Target Finder--Set energy performance targets and identify ways to close the gap between energy estimates and a building s actual operation (whole-building energy performance) Adopt Best Energy Management Practices ENERGY STAR Guidelines for Energy Management Purchase ENERGY STAR qualified Products More than 50 product categories Building Operation Commissioning - Ensure all systems comply with design intent Use Portfolio Manager Earn the ENERGY STAR

23 Need for a Rating System for Buildings-Portfolio Manager Is 80 kbtu/sf/yr high or low for a building? Statement of Energy Performance EPA Rating Fuel Efficiency MPG Is 60 MPG high or low for an automobile?

24 Complementary Approach Complementary Approach

25 Follow Through Post-occupancy assessment of energy performance EPA s building energy performance rating system Portfolio Manager Input data include: Building characteristics gross square feet, number of occupants, operating hours/week, 12 months of energy data Output data Percentile ranking (1 100) 70, 75, 80 LEED-EB Energy ranking prerequisite of 67

26 LEED-EB & EPA Energy Performance Rating Use Portfolio Manager to receive up to 10 points towards your LEED-EB application Prerequisite Rating Earn the ENERGY STAR EPA Rating LEED-EB Points

27 Become an ENERGY STAR Partner ENERGY STAR helps you and your organization take control of energy use by providing the best information, tools, and resources for improving energy and environmental performance. Download the partnership letter at

28 Become an ENERGY STAR Leader ENERGY STAR partners who demonstrate continuous improvement organization-wide, not just in individual buildings, qualify for recognition as ENERGY STAR Leaders How to become an ENERGY STAR Leader Become an ENERGY STAR Partner Benchmark all buildings and measure district-wide improvement Improve energy use by 10%, 20%, 30%, or more
