LEED®
Leadership in Energy and Environmental Design
The U.S. Green Building Council is a coalition of leaders in the building industry promoting environmentally responsible and healthy buildings.
Its core purpose is to transform the way buildings and communities are designed, built and operated.
Why Was LEED® Created?
1. Define “green” by providing a standard for measurement
2. Prevent “greenwashing” (false or exaggerated claims)
3. Use as a design guideline4. Promote whole-building, integrated design
processes
Test
What is the LEED System?
LEADERSHIP inENERGY andENVIRONMENTALDESIGN
A leading-edge system for certifyingDESIGN, CONSTRUCTION, & OPERATIONSof the greenest buildings in the world
Scores are tallied for different aspects of efficiency and design in appropriate categories.
For instance, LEED assesses in detail:
1. Site Planning2. Water Management3. Energy Management4. Material Use5. Indoor
EnvironmentalAir Quality
6. Innovation &Design Process
Test
Levels of LEED Ratings
Green Buildings worldwide are certified with a voluntary,consensus-based rating system.USGBC has four levels of LEED.
What is Sustainability?
“Meeting the needs of the present without compromising the ability of future generations to meet their own needs”
Bruntland Commission
Presidents council on Sustainable Development
Building Sustainability
Considers a building’s total economic and environmental impact and performance, from material extraction and product manufacture to product transportation, building design and construction, operations and maintenance, and building reuse or disposal
The Need for Sustainable Practices
Why are we doing this?
8% of a buildings environmental impact occurs at construction, 92% over it’s operational lifetime.Energy and operating costs savings of 20-50% are commonImprovements to indoor environments, access to views, increased daylight, fresh air, personal environmental controls increase occupant performance 2-16%Create the best possible workplace, improved health, morale, productivity
LEED® Facts
There are LEED projects in all 50 states AND 12 COUNTRIES
Total square feet of space registered or certified: 774 million sf
As of January, 2008 there were:-34 certified EB buildings and 234 registered EB buildings-504 certified NC buildings and 3,738 registered NC buildings
May, 2008 – 54 certified EB and 757 registered EB buildings
LEED® - EB Certification Levels
Certified 32-39 pointsSilver 40-47 pointsGold 48-63 pointsPlatinum 64-85 points
All prerequisites must be met to earn LEED certification
The Challenge?
Moving sustainability from the abstract to something measurable and meaningful
What can we do?
Sustainable Sites (SS) Goal
Reduce site maintenance operations and maintenance costs while creating and maintaining an outdoor space that is healthy for building occupants and local plant and wildlife.
Promote use of public and alternative transportation.
Sustainable Sites (SS) Strategies
Use green cleaning products on exterior of the buildingReduce or eliminate architectural lightingUse Integrated Pest Management (IPM) techniquesMulch grass clippings, limit fertilizer, erosion controlUse native plants, low water using trees and shrubs
Sustainable Sites (SS) Strategies
Provide secure bike storage and shower facilitiesPromote commuter services and options –494 Corridor ProgramProvide preferred parking spaces for hybrid or alternative fuel vehicles, car pools
Water Efficiency (WE) Goal
Maximize water efficiency to reduce the burden on potable water supply and wastewater systems
Water Use = Energy Use
Energy is needed to treat wastewater, resulting in more energy consumption and resource consumption to build power plants.
About 8% of all electricity used in the US is expended in the delivery and treatment of potable water, roughly the amount of electricity needed to power 4.5 million private homes each year.
Did you know..?
Letting your faucet run for five minutes uses about as much energy as letting a 60-watt light bulb run for 14 hours.
Water Efficiency (WE) Strategies
Low-flow sensor faucets w/ automatic shut-offUltra low-flow fixturesAdjust irrigation based on precipitation expectedMeter irrigation separately to catch breaks in linesUse new technologies to automate sprinkler and drip irrigation scheduling
Energy & Atmosphere (EA) Goals
Optimize energy efficiencyEncourage on-site and off-site renewable energy sourcesReduce ozone depletion (mechanical and life safety systems)
Energy Star®
The Portfolio Manager tool allows companies to benchmark their properties energy use to their peers, the industry and their own performance over time
EPA’s Energy Star® system generates a rating between 1 and 100 that can be used to establish a baseline for energy performance, and over time, to measure and verify improvements.
Crescent Ridge Corporate Center Rating of 91!
Energy & Atmosphere (EA) Strategies
Close blinds on south and west elevations before the weekend to reduce solar heat gainEncourage employees to turn off equipmentPerform regular after-hours night walk-throughs to verify systems and lights are on or off as programmedPurchase Energy Star appliances and equipment
Energy & Atmosphere (EA) Strategies
Install occupancy sensors & timer controls De-lamp where possibleInstall high-efficiency LED exit signsEvaluate after hours usage & adjust building systems run times to reduce unoccupied space energy use
Energy & Atmosphere (EA) Strategies
Implement Janitorial best practices – team cleaning, day cleaning, early pm start, reduces night lighting requirementsCalibrate thermostats, adjust mechanical equipmentLow flow faucet fixtures reduce energy needed to heat the water
Materials & Resources (MR) Goals
Reduce the quantity of waste while improving the building environment through responsible procurement choices
“Reduce, reuse, recycle”
Materials & Resources (MR) Strategies
Green Cleaning ProgramExpand recycling program (organics, techno trash)Encourage recycling participationEncourage sustainable purchasing (guidelines on website soon)Replace lighting with most energy efficient and sustainable products availableTenant Improvement RecommendationsConstruction Waste Management (66% recycled)
The Case for Green Cleaning Products
Each year, 6 billion pounds of chemicals are used to clean commercial buildings. The majority of these products are formulated from ingredients derived from nonrenewable resources.The commercial cleaning industry consumes approximately 4.5 billion pounds of janitorial paper products which requires the cutting of an estimated 25 to 50 million trees. Additionally, the processing and bleaching of this paper consume huge quantities of water and energy.
The Case for Green Cleaning Practices
Reduced after-hours energy use with daytime or team janitorial methodsReduced health-related issues for janitorial staff due to reduced exposure to toxic chemicals and improved equipmentImproved IEQ for occupants as a result of non-toxic cleanersLess staff turnover (better quality) in janitorial staff
Indoor Environmental Quality (IEQ) Goals
Enhance indoor environment in buildings, thus contributing to the health, well-being and productivity of the occupants
USGBC estimates that we spend 90-95% of our time indoors.
Indoor Environmental Quality (IEQ) Strategies
Install occupancy controls on lighting circuitsNo High Volume Copying PolicyAdditional monitoring of thermal comfort conditions Encourage daylighting and views to outsideLow VOC interior finishes and building productsIntegrated Pest ManagementBest Practices IAQ Plan
LEED Certification Process
2008 Process to include:1. Draft new Policies and Procedures2. Report continuously on performance –
ongoing procedure, continues to ensure Best Practices are implemented
3. Evaluation by USGBC, Certification Award4. Continue to adopt best practices in
operating procedures.
How Can You Get Involved?
Recycling ParticipationProvide PM with Shredding DocumentationTurning out lights, computers, equipmentTurning off running faucets, reporting leaksClosing south and west exterior blinds on weekends during the cooling seasonPurchase recycled or green productsGreen Earth Dry Cleaners (Door to Door)Commuting and Alternative TransportationPurchase Energy Star Products
