U.S. ARMY ENGINEER RESEARCH AND DEVELOPMENT CENTER Construction Engineering Research Laboratory (CERL) Cooperative Research And Development Agreement (CRADA) Primary Focus & Objective - Joint Base San Antonio Goal of this project is to design and build a high performance building at Joint Base San Antonio to demonstrate the technologies that can be incorporated into the building and the return on investment that can be achi Other Department of Defense & Federal Agencies Locations Explore Third Party Financing Opportunities - Energy Savings Performance Contracts (ESPC) - Independent Savings Plan Company (ISPC) - Department of Energy (DOE) - Private Sources

U.S. ARMY ENGINEER RESEARCH AND DEVELOPMENT CENTER Design Build of Energy Efficient High Performance Buildings There are a number of design and construction strategies that can be used: Tight building envelope Energy efficient HVAC ( geothermal ) Natural day lighting Energy efficient lighting Occupancy sensors Solar or geothermal domestic water heating Water conservation Gray water recycling Rain water catchment Occupancy sensors & control systems can lead to efficient building operations and performance

BEGINS WITH THE LEARNING PROCESS

EDUCATION - ON-GOING PRACTICE Learning Construction Terminology, Techniques - New Construction - Retrofit & Renovation Educating End-User operations and behavior changes Third Party Financing PRESENTATIONS Corp of Engineers - Fort Worth Joint Base San Antonio Energy Manager for Joint Base, Randolph AFB and Lackland AFB SAME San Antonio Post SAME Tulsa Post SAME Savannah

ENERGY EFFICIENT HIGH PERFORMANCE BUILDINGS NEW CONSTRUCTION SOLUTIONS There are a number of design and construction strategies that can be used in a high performance building. The basic elements may include: Tight Building Envelope - Walls, Windows & Roof Insulated Concrete Forms (ICF) - Blast Resistant - Withstands 250 MPH Winds - Energy Efficient - R-50 - 4-hour fire protection Geothermal - HVAC & Water Heating Solar - Water Heating

Information Technology

Natural Day lighting

Wireless Technology

Night Lighting

Occupancy Sensors

Energy Efficient Lighting

Water Conservation Gray Water Recycling Rainwater Catchment Become self-sufficient with renewable energy like Solar Photovoltaic or Wind Turbines

The final step in a high performance building is building operations. Occupancy sensors and control systems are important, but everyone in the building has to be dedicated to efficient operations to ensure building performance.

PREPARE THE ENVELOPE RETROFIT & RENOVATION

Identify Assets Long-Term Use of Assets Enhance the Assets Establish a Controlled Environment Prepare a detailed analysis of building Make educated decisions on return on investments for different types of Energy

HIGH PERFORMANCE BUILDINGS EVOLVE INTO NET ZERO ENERGY BUILDING

A Energy Efficient High Performance building can evolve into a Net Zero Energy Building with the addition of an on-site renewable energy source such as: Solar Wind Geothermal

The critical factor is reducing the building’s energy consumption so that a renewable energy source can be affordable and located on-site.

Health Care Hospitals and other health care providers are slow to adopting energy efficient principles. However, hospitals and medical clinics are beginning to see the value of reducing energy costs. Hospitals can operate at over 1,000 kBtu/sf yr. Energy efficient facilities can operate at or below 200 kBtu/sf yr. Clinics and outpatient surgery centers can operate even more efficiently.

Kosair Children's Medical Center – Brownsboro (a pediatric outpatient surgery center with a 24/7 emergency department and full diagnostics such as CT and MRI)
