3 Current energy initiatives: 2030 Challenge Adopted by the American Institute of Architects (2030 Commitment) Incremental decreases in fossil fuel consumption to reach carbon neutrality by year 2030 All new buildings and major renovations, annual building-area match in renovations to existing buildings

4 Current energy initiatives: ASHRAE 90.1 Significant increases in standards from 2007 to 2010 (18.5% reduction in energy use) Requires consideration of entire building envelope, not only MEP systems Use less energy Use that energy efficiently Then rely on generated renewable sources

5 Strategies of the 2013 Standards Envelope Solar Ready Commissioning Compliance Documentation Costs

6 Current Commercial Building Energy Code Adoption Status States with the most stringent energy codes

7 California Energy Commission Title 24, Part 6: 2013 Building Energy Efficiency Standards CEC created in 1974 to develop & maintain energy efficiency standards Updated approximately every 3 years 2013 Standards went into affect January 1, 2014 CEC goal of reaching Zero Net Energy ZNE = Using a combination of building efficiency features and on-site/near-site generated power to meet 100% of a building s annual energy demand ZNE for residential construction by 2020 ZNE for commercial construction by 2030

8 Compliance Documentation Required registration of compliance documents went into affect January 1, 2015 Certificates of Compliance Certificates of Installation Certificates of Acceptance Testing For new construction and alteration of nonresidential buildings Incorporated into construction documents Submittal to data registry creates electronic versions of registered documents to be made available to authorized users Energy consultants, builders, building owners, contractors and installers, enforcement agencies, the California Energy Commission, etc. Utilized to satisfy public information requests, perform research and program evaluation

9 Certificates of Compliance For completion during early design phases and construction documents z

10 Certificates of Installation For completion during construction site visits z z

11 Certificates of Acceptance For completion at activation of building systems z z

12 Building Envelope Increase low-slope cool roof requirements Increase reflectance from 0.55 to 0.63 for new construction and alterations Section 140.3(a)1Aia1 Section 141.0(b)2Bia Established a maximum air leakage rate 0.04cfm/SF, except in mild climate zones Consistent with air leakage requirements in IECC Section 140.3(a)9B Increased fenestration requirements to reduce solar gains and increase visual light transmittance for daylighting 0.36 U-factor, 0.25 SHGC, VT 0.42 for fixed windows Required values vary for operable windows and skylights. Section 104.3(a)5B, C and D Added mandatory minimum wall and roof insulation requirements Section 120.7

13 Certificates of Compliance: Building Envelope NRCC-ENV-01-E, Envelope Component Approach (Opaque Surfaces and Cool Roof) NRCC-ENV-02-E, Envelope Component Approach (Windows) NRCC-ENV-03-E, Solar Reflectance Index Calculation Worksheet NRCC-ENV-04-E, Envelope - Daylit Zone Worksheet NRCC-ENV-05-E, U-Factor and SHGC Fenestration Certificate Label

14 Solar Ready Provisions to more easily enable the future addition of solar systems to nonresidential construction. Solar electric systems Solar water heating systems Mandatory requirements for buildings 3 stories or less Section (a)4 Creation of unobstructed Solar Zones Located on-site or near-site Roof of building Roof of another structure within 250 feet of building Covered parking installed with the building Total Solar Zone to be 15% of total roof area or that portion of the roof receiving annual solar access of 70% or greater Structural implications in initial design Accounting for a loading zone of a certain surcharge for TBD-technology Costs could vary from 0% to +20%, largely based on geometry of building Indication of future interconnection pathways for required conduit and plumbing

15 Certificates of Compliance: Solar Ready NRCC-SRA-01-E, Solar Ready Areas NRCC-SRA-02-E, Minimum Solar Zone Area Worksheet

16 Commissioning Moved Part 11 commissioning requirements to Part 6 for energy-related building components Section Added mandatory requirements for design-phase commissioning Early review of design intent documents Highlighting efficiency specifications in both construction documents and Standards compliance forms Section 120.8(d) Added performance standard compliance requirements to produce whole building performance rating twice during project process During design permit stage ( design rating ) After construction acceptance testing ( as-built rating ) Section 120.8(g) Commissioning Plan due at permit submittal, commissioning measures to be indicated in construction documents

17 Certificates of Compliance: Commissioning NRCC-CXR-01-E, Design Review Kickoff Mandatory design-phase commissioning meeting Selection of Design Reviewer based on size of project Review of design intent, owner s project requirements and basis of design

18 Certificates of Compliance: Commissioning NRCC-CXR-02-E, Commissioning Construction Documents (Envelope)

19 Certificates of Compliance: Commissioning NRCC-CXR-03-E, Commissioning Construction Documents (Simple HVAC Systems) NRCC-CRX-04-E, Commissioning Construction Documents (Complex Mechanical Systems)

20 Certificates of Compliance: Commissioning NRCC-CXR-05-E, Commissioning Design Review Signature Page

21 Commissioning Plan To be developed at time of permit submittal Reiterate owner s goals for energy efficiency, list systems to be commissioned, identify plans for testing equipment Original design intent Testing condition requirements Measurable criteria Process, activities and schedule of testing

22 Functional Performance Testing Completion of required Certificates of Installation and Certificates of Acceptance Site visits conducted by commissioning firm to ensure systems are installed and functioning correctly Including system-to-system interfacing Training manual for maintenance staff and final report provided to owner

23 Cost Implications Energy-efficient systems and strategies add an estimated to add $5-7 per SF to construction costs Additional increased costs to consider in project budget Design Fees Architectural, Structural, MEP Commissioning Useful to ensure building systems are installed and working properly CEC requirements go beyond typical commissioning measures

24 Alterations to Existing Buildings Compliance depends on type and extent of work Adding to energy load = system must comply with current Standards Adding/replacing parts but not adding to energy load = limited compliance required i.e. Rerouting HVAC, no additional load = only installation and insulation must comply i.e. Reconfiguration of lighting adds switches, no additional load = switches must comply May depend on percentage of building being altered i.e. Reroofing limited to 50% of existing roof or 2,000 SF before compliance is required Tenant Improvement considered new construction in an existing building New systems must comply, existing depend on extent of alteration

25 Additions to Existing Buildings 3 methods of evaluation Option 1 Addition Alone Addition considered separated from existing building by wall with no heat transfer value Based on relationship of existing building and addition Option 2 Existing-Plus-Addition Calculated on 3 features: Existing building features to remain unaltered All altered features designed to comply Addition designed to comply Compliance is balanced by combination between a relatively inefficient addition and energy improvements to existing building Option 3 Whole Building as All New Construction Whole building, existing and addition, comply with Standards for new construction (envelope, lighting and mechanical) Only practical if existing building is at or will be improved to current Standards
