Introduction to Green Buildings and LEED EB
Leadership in Energy and Environmental Design
The basics of greening existing commercial non-residential buildings
http://www.usgbc.org/
Definition of Green Building
• Practice of increasing the efficiency with which buildings and their sites use energy, water, and materials. • Holistic approach of construction, operation, and maintenance
What are Green and Sustainable Buildings?
• Use energy, water, and materials • Create healthier work, learning, and living environments • Contribute to improved health, comfort, and productivity • Are cost-effective
What is Sustainability?
• Leaving the world better than you found it • Taking no more than you need • Trying not to harm life or the environment • Making amends if you do
• It can also be defined as: meeting the needs of the present without compromising the ability of future generations to meet their own needs

Energy
• Finite Resources. The second law of thermodynamics leads to the conclusion that energy cannot be used over and over indefinitely, that the available usable energy is a finite resource.
• This is because each time energy is converted from one form to another, it looses energy during the transition, usually as heat. • While there are still large supplies of coal, oil, and natural gas, worldwide demand is increasing as the amount of new supplies being found is decreasing.
Non-renewable Energy Sources
Renewable Energy Sources
Energy Cost
• Energy costs have risen dramatically over the past 7 – 10 years and will continue to rise. • Some areas have seen increases above 125% in electrical and natural gas costs • Experts predict another 70% increase over the next year • Main reasons for escalating cost of electricity is rising oil and natural gas costs created by worldwide demand

Overview of LEED-EB
LEED for Existing Buildings is
• a set of performance standards for the sustainable operation and upgrades of existing buildings. • It helps building owners and managers solve building problems and improve building performance.
What is LEED EB - O & M?
• LEED EB Operations and Maintenance is the latest revision of the LEED Existing Building program. • It is a program that should continue for the life of the building to ensure continued success. It should be considered a continuous improvement program. • One of the requirements of LEED EB O & M is the creation of a comprehensive building operations manual. • The list will also include standard operating procedures like Indoor air quality procedures, filtration systems and types, chiller and boilers information such as tonnage and horsepower, cooling tower information, water treatment procedures and parameters etc.
LEED EB O & M
• LEED EB O & M requires that the building establish a set of policies and procedures covering a variety of issues such as: • Building Exterior and Hardscape Management Plan • Integrated Pest Management, Erosion Control and Landscape Management Plan • Alternative Transportation Program • Stormwater Management Plan • Cooling Tower Water Management Plan • Building re-commissioning Plan • Sustainable Purchasing Policy
LEED EB O & M is also:
• • • • • • Building Operations Plan Solid Waste Management Policy Environmental Tobacco Smoke Policy Green Cleaning Policy Refrigerant Management Plan IAQ Management Plan
• Some of these policies are required to meet prerequisites
It’s not just a project, it’s a journey over time.
• LEED EB O & M is a journey that continues for the life of the building • It’s a program that helps you establish guidelines and operating procedures that are building specific • It requires facility management to adopt policies and procedures that are relevant to sustainable buildings • It is more than energy reductions, it covers the entire building function and use
Six Categories of LEED EB O & M

17th Street – 41 years old
16th Street – 70 years old
M Street – 21 years old
Where it all Began
• Lighting – EPACT 1992 Began a series of lighting upgrades • Facilities evaluation Needed to know where we were • Created a Plan Looked at all mechanic systems/technology • Capitol budget Competition for corporate funds
EPACT and Lighting
Replaced recessed lamps of 100 watt to 300 watt with halogen type of 50 to 100 watt. Conversion from T-12 & magnetic ballast to T8 & electronic ballasts. Replaced exit signs with LED type. Motion sensors CFL’s – finally a better solution
Facility Evaluation
• • • • • • • Looked at aged mechanical systems Life Safety – fire alarm systems Human comfort- restrooms Vertical transportation Environmental issues – CFC’s/Halon Water saving measures Air filtration
5 Year Master Plan
• • • • • • • Chillers Cooling towers Boilers AHU replacement Elevator modernization Restroom ADA issues Energy Management • • • • • • • • Roofing Landscaping Asbestos Fire alarm systems Fire suppression Kitchen refrigeration Motor controls Water use
The Capitol Budget
It’s like “Dialing for Dollars”
Process
• • • • • • • DC Municipal Bond $14,000,000 Short spending time/hurdles Capitol Improvements Encouraged to use DC owned businesses Informed 6 months into program Fast paced projects
Our First Major Project Eliminate CFC’s and Increase Energy Performance
Water Efficiency – Energy & Atmosphere
This is a 1000 ton heat exchanger used for free cooling.
1000 Ton Plate and Frame Heat Exchanger – Increase Energy Performance
We needed to gain maximum efficiency from our new chillers.
• Although the old cooling towers (20 yrs.) were rated at 1000 tons, this was prior to towers being CTI certified. The new cooling towers are CTI certified to be 1000 tons and have increased our chiller efficiency due to lower condenser water temperatures.
Variable Frequency Drives were installed on all secondary pumps.
• Controlling of the pumps is by pressure sensors in the piping. This controls the VFD’s and allows the pumps to only deliver the amount of water necessary, thus reducing energy use. The primary pumps are controlled by the chillers microprocessor.
We also replaced several 40 year old air handling units.
• Efficiencies in coil designs, use of premium efficiency motors with VFD’s and a digital control system make the new units more efficient to operate.
