Transcript of Energy Efficiency Strategies

Gavin Dillingham, PhD
Research Scientist
Houston Advanced Research Center Energy Efficiency Strategies CATEE
2012 Data Driven Decision Making Collect and organize building and utility data.
Facility data – square footage, year built, hours of operation, etc.
Utility data – minimum of 12 months of bill data
Consumption (kWh, mcf) and monthly cost
Energy management system Take your KPIs and compare them to other District’s in the region;
Benchmarking helps to identify opportunities for District
Benchmarking helps to prioritize and focus on areas of improvement Benchmark Your Facility Implement Energy Management System to reduce utility and operating costs and identify energy efficiency opportunities.
Web-based enterprise energy management system
Provides interval data
Utility tracking and utility bill validation
Baseline development, benchmarking and trend analysis tools
Energy cost savings analysis,
Energy budgeting and planning
Leverage your smart meters Energy Management System Retro-Commissioning
Process of discovering, correcting and optimizing issues that prevent building systems from operating at their peak efficiencies Continuous Retuning
Periodically tuning BAS ensures maximum building energy efficiency and occupant comfort.
Benefits: Cost and Persistence Vending Machines Reduce Plug Load Preventive Maintenance “Tell me and I'll forget;
show me and I may remember; involve me and I'll understand.” Change the way we use our buildings through awareness and education
Consciousness through Transparency
Information Sharing
School Specific Reports
Education and Reinforcement
Resources
Incentives Behavioral Change Promote long-term behavioral change to reduce resource consumption and increase recycling
Low cost/no cost effort
Provide resources and guidance on implementing Challenge at each school
Incentives and Recognition Green School Challenge Set Goals and Performance Targets
Educate
Information and Feedback
Provide Incentives Sustainability teams started by each school to implement program at the schools.
Team made up of students, faculty and staff
Develop own policies and processes to successfully compete in the Challenge
Provided resources to succeed from the Energy and Sustainability Division of CFS Green Teams Upgrade of HVAC, Lighting, Controls, Building Envelope, etc.
Life Cycle Cost Analysis
Be careful of focusing only on first cost
Long term view
Purchase Options EPC is a process to pay for energy efficient upgrades
ESCO guarantees minimum savings, and project is paid for out of those savings
Entities with little/no funding can improve energy efficiency
Justification for EPC - financing method - allow us to fix equipment without having to use emergency funds
Accumulation of deferred maintenance cost on older buildings. Pay for equipment that we currently don't have funds to pay for.
Lack of available funds to make much needed repairs and improvements to infrastructure.
Comfortable learnig environment for students; more conducive learning environment; significant improvement in learning environment
Inefficient energy use due to age of infrastructure.
Rising energy and operational costs
20% Decrease in Energy Costs Energy Performance Contracting Tax Exempt Lease Purchase (TELP) (3% to 3.5% rate)
Qualified School Construction Bonds (QSCB) ($538 million/ .25% rate) – tax credit bonds
Internal Funding Sources –Bond money; energy budget savings
Mixed Funding Sources – pay down with internal funds and finance with TELP and/or QSCBs
LoanStar with the State Energy Conservation Office Financing Options Incentives and Credits – buy down project costs
DSIRE - Database for State Incentives for Renewables and Efficiency
179D tax credit – EPAct 2005
CenterPoint SCORE program and LED incentive program
State Energy Conservation Office Grants
Department of Energy Grants if come available “The great thing in the world is not so much where we stand, as in what direction we are moving.”

- Oliver Wendell Holmes www.houstonisd.org/greenschoolchallenge Single-Stream recycling is a process in which materials are all mingled together with no sorting required by you, the recycler.

Aluminum cans and plastic bottles can be recycled together with newspaper, cardboard, etc.

The recyclable material is picked up on a regular basis and taken to a Materials Recovery Facility (MRF) where the recyclable materials are separated and sent to various markets for sale. Single Stream Recycling
