"SB 668" building requirements

Background What are the requirements? How does this affect my agency? What are the reporting requirements? Financial component (project costs, life cycle cost analysis, projected savings, incentives, etc.)

Background

Senate Bill 668

Introduced by State Senator Janet Cowell AIA involvement and input Initially based on LEED Silver with an emphasis on energy 30 % Improvement in Energy Performance LEED is not required

Does not address other environmental or sustainability topics

­

Focus on Energy and Water Performance

Background What is Senate Bill 668?

Performance Standards for Sustainable, Energy-Efficient Public Buildings Applies to: State-Owned Buildings

Public Agency Funded in whole or in part by ...State Capital Budget Community Colleges, when using State funds

Requirements

· Energy Efficiency Standard · Energy Consumption At least 30% less... · ASHRAE 90.1-2004

­ American Society of Heating, Refrigerating and Air-Conditioning Engineers ­ Energy Standard for Buildings Except LowRise Residential Buildings ­ IECC and NC Energy Code

· Renovations ­ 20% less energy · Aggressive goal - - Achievable goal

Requirements

· Major Facility Construction Project

­ > 20,000 gross square feet

· Major Facility Renovation Project

­ Cost > 50% of Insurance Value ­ Renovation > 20,000 gross square feet

· · · · ·

Energy-Efficiency Standard Water Use Standard Performance Verification Separate Utility Meters Performance Review of Program

Requirements

· Building Commissioning = Cx

­ Starts by Schematic Design ­ Commissioning Agent (CxA), Licensed Engineering Firm in North Carolina

· Definition of Building Commissioning

(State of Georgia, Commissioning Guidelines, 2002.)

­ A planned and integrated systematic process to ensure, through documented verification, that all Building Systems perform interactively according to the Owner's Project Requirements (Design Intent). ­ Commissioning procedures require a collaborative team effort and begin in the predesign phase, continue through the design and construction phases into the occupancy phase, including the training of O&M staff.

Requirements

· Building Modeling

­ More than a useful tool ­ Had not done enough previously ­ Tangible Results ­ Decision-Making Tool During Design ­ Quantify the 30% Performance Improvement

Requirements

· Measurement and Verification

­ Too soon to tell ­ 12 month performance ­ Commitment from Architect/Designers ­ Responsibility for Energy Performance

Future Direction

· Whether Program should be expanded to include additional public agencies · Future Legislation · NC Energy Conservation Code

­ Building Code Council ­ Applicable to All Commercial Buildings

· Example for others to Model After

­ County or Municipal Governments

· ASHRAE Standard Project Committee 189.1 (SPC 189.1) Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings

­ More comprehensive than 90.1

Effective Date of Efficiency Standards

· Projects in Schematic Design after August 8, 2008

Cost Impact

· · · · · · · **Advanced Planning** Design Construction Operation "Front Loaded" cost Additional Deliverables Incentives

­ Tax Credit ­ May be transferrable to Designer ­ Utility Companies Demand Side Management Programs

Estimated Cost Increase from Efficiency Standards: Construction Cost Design Commissioning Total Estimated Cost Increase + 2.5% + 1.0% + 0.5-1%

+ 4.0%
