Sustainability and Energy Services AGENDA • Introduction • Commissioning • Industry Changes • Retro-Commissioning • Energy Auditing • Sustainability PERSONAL QUALIFICATIONS Colin P. Fay, PE LEED® AP BD+C, O+M AEE Certified Energy Auditor Colin joined PDC in 2009, and has relevant experience in building HVAC systems, plumbing systems, and fire protection systems. Supporting his design experience and expertise, he also has specialized certifications including Certified Energy Auditor certification, as well as his LEED-AP BD+C and O+M. Colin is active in the field of sustainable design including attendance at national conferences and training seminars on LEED credit interpretation, LEED credentialing, and credit documentation. Locally, he is an active member of the Cascadia Green Building Council chapter, serving as the Alaska Branch Chair. Additionally, Colin spearheaded an internal LEED training program at PDC that included marketing, organizing, and developing coursework for the in-house training of employees to achieve the LEED Green Associate Credential. CHANGES IN OUR INDUSTRY Why now? Energy cost increases Push for sustainability & environmental responsibility Improved return on investment Alternative energy technology is now proven Building codes ENERGY AUDITING WHAT IS AN ENERGY AUDIT What is an energy audit? What is the goal of an energy audit? Audit levels: Simple vs. in-depth LCCA vs. simple payback Identifying energy usage Grant opportunities & institutional requirements AHFC DEED Private Banks AUDIT PROCESS SITE WALK THROUGH General Identify current code violations Identify maintenance improvement opportunities Collect equipment information BUILDING ENVELOPE Review as-builts Visual inspection IR camera MECHANICAL System operation Functionality Remaining life expectancy Efficiency Controls ELECTRICAL Lighting levels Lighting type Occupancy and day-lighting controls IR Camera for circuits EEM/ECM DEVELOPMENT Energy Efficiency Measures (EEM) Energy Conservation Measures (ECM) Engineered calculations Energy savings Cost/benefit analysis Simple payback LCCA Return on investment Report process COMMISSIONING COMMISSIONING What is Commissioning? “Commissioning is a systematic process of ensuring that all building systems perform interactively according to the design intent and the Owner’s operational needs.” What is Retro-commissioning? Commissioning for existing buildings. Usually includes a facility assessment Who Should Commission? GOALS OF COMMISSIONING Ensures the building operates properly Reduce warranty calls Lower operational costs Achieve expected energy savings Provides 3rd party voice Ensure proper staff training WHAT SHOULD BE COMMISSIONED? Systems: Automatic Function Complex Facilities Health Care Laboratories Schools Industrial Projects Power Plants Water/Waste-water Plants Energy Efficient Projects LEED Rural/Remote Projects LEVELS OF COMMISSIONING Which should you choose? Simple Couple of systems Simple systems Advanced Complex systems New maintenance staff Critical facilities LEED RETRO-COMMISSIONING Existing Buildings or Remodels Normally includes Site Assessment Corrective Actions (CCA): Basic Repairs Conservation Measures (CCM): Low cost upgrades, < 1 yr How does this benefit? All of the benefits of commissioning Lower energy costs Better building comfort and controllability Save a lot of money in remodel costs SUSTAINABILITY SUSTAINABILITY “Sustainability” vs. “Green Design” Sustainability Green Construction HOW DOES IT DIFFER FROM ENERGY SAVINGS Energy is the basis of sustainable design. BENEFITS OF GREEN CONSTRUCTION increased productivity environmental responsibility fewer sick days SUSTAINABLE DESIGN better staff retention marketing better test scores in schools HOW IS THIS ACHIEVED? 3rd Party Certification LEED – Leadership in Energy and Environmental Design Green Globes – Building Owners and Managers Association Energy Star COMPLIANCE VERIFICATION IECC & ASHRAE 90.1 Energy Standard for Building Except Low-Rise Residential Buildings IGCC & ASHRAE 189.1 Standard for the Design of High Performance of Green Building Typically 30% savings from 90.1 LEED Depending on Jurisdiction Owner Requirements Certification vs. Design to LEED Standards Achieve the benefits with less cost COST of LEED LEED Specific • Documentation • Registration & Application fees to GBC High Performance Design • Research • Energy Modeling • Commissioning • M&V Construction & Traditional Design LIVING BUILDING CHALLENGE Seven petals Site Water Energy Health Materials Equity Beauty For more information, visit www.living-future.org/lbc or join the Cascadia Green Building Council (email [email protected]) QUESTIONS http://www.pdceng.com [email protected]
