Local adoption and enforcement required by July 1, 2015. Applies to all construction in the state of Maryland – up to individual jurisdictions to implement the code. Cannot be weakened. Intended to provide flexibility – which also promotes complexity Includes requirements for: Building Envelope Mechanical Systems Service Water Heating Electrical Power and Lighting Systems Total Building Performance Commissioning

5. IECC Definitions Addition: an extension or increase in the conditioned space floor area or height of a building or structure C502.1 General. Additions to an existing building, building system or portion thereof shall conform to the provisions of this code as those provisions relate to new construction without requiring the unaltered portion of the existing building or building system to comply with this code. Repair: the reconstruction or renewal of any part of an existing building for the purpose of its maintenance or to correct damage Section 501.3 Maintenance. Buildings and structures, and parts thereof, shall be maintained in a safe and sanitary condition. Devices and systems that are required by this code shall be maintained in conformance to the code edition under which it was installed…

6. IECC Definitions Alteration: Any construction, retrofit or renovation to an existing structure other than repair or addition that requires a permit. Also, a change in a building, electrical, gas, mechanical or plumbing system that involves an extension, addition, or change to the arrangement, type or purpose of the original installation that requires a permit. C503.1 General. Alterations to any building or structure shall comply with the requirements of the code for new construction.

IECC Definitions Residential Building: includes detached one- and two- family dwellings and multiple single-family dwellings (townhouses) as well as group R-2, R-3 and R-4 buildings three stories or less in height above the grade plane Commercial Building: all buildings not included in the definition of “residential building”

8. Residential or Commercial? Cambridge Hall – 4 stories above grade – Commercial Code Carroll Hall – 3 stories above grade – Residential Code Mixed use – one story commercial, 2 stories residential – BOTH Commercial and Residential Code Mixed use – one story commercial, four stories residential – Commercial Code

36. LEED vs. IECC Maryland base code is IECC 2015/ASHRAE 90.1-2013 LEED v3 Energy Model based on ASHRAE 90.1-2007 (Appendix G) LEED v4 Energy Model based on ASHRAE 90.1-2010 (Appendix G) Note: Section C102.1.1 allows the code official to deem a project using an “above code” program (including mandatory requirements) to be in compliance with the code. Neither LEED v3 nor LEED v4 would be considered “above code” compared to IECC 2015.

37. LEED beyond IECC LEED prerequisite - whole building energy metering LEED Credits beyond code: Enhanced Commissioning Advanced energy metering Renewable Energy Production

38. High Performance Building Program (Fully state funded projects greater than or equal to 7,500 SF) requires either LEED Silver OR IgCC “Performance based designs shall demonstrate an energy savings of at least 15% over the current version of the International Energy Conservation Code IECC).” (EUIp/EUIb) =<.85 of current IECC EUI – “Energy Use Intensity” measured in kBtu/sf-Yr

39. New University of Maryland College Park Energy Analysis Requirements - During Design Energy modeling early in the process to inform the design Preference for “open source” modeling software Energy modeling reports at each design phase

40. New University of Maryland College Park Energy Analysis Requirements – After Occupancy As Built energy model which incorporates any major changes that occur during construction Review of energy usage 12 months after occupancy to identify areas where building is not performing as designed and provide recommendations for addressing issues

41. From: Energy and Energy Cost Savings Analysis of the 2015 IECC for Commercial Buildings prepared for the U.S. Department of Energy August 2015 Looking to the Future – codes moving to Zero Net Energy Estimated site EUI for a one or two story building in our area to achieve ZNE is 21 kBtu/sf-yr. 15% better would be 25 kBtu/sf-yr

42. Gaps in documentation – daylighting calculations, mechanical equipment efficiency requirements, insulation information often missing No industry standard - documentation there but “hidden” – sometimes on drawings, sometimes in specs, sometimes in different drawings or specs than we expect, sometimes in a separate calculation submission Narrative explaining calculations and confirming code compliance is unclear or missing Challenge s

43. Multiple energy models are required for different phases of design LEED and IECC require different modeling baselines and methodologies Keeping up with technological “advances” Post-occupancy Energy model not indicative of actual building energy use Building systems too complicated to manage properly Building users by-pass energy saving systems Preventive maintenance

44. Recap All projects in Maryland must follow the 2015 International Energy Conservation Code – new construction, renovations, additions, alterations, equipment replacements (for Washington, DC and VA – 2012 IECC) Four compliance paths meet the requirements of the IECC – 2015 IECC Prescriptive Path, 2015 IECC Performance Path, ASHRAE 90.1-2013 Prescriptive Path, ASHRAE 90.1-2013 Performance Path. Choose one - no mixing and matching! Construction documents must include energy code information to confirm compliance. Mandatory inspections must be documented during construction. There may be additional requirements from the jurisdiction and/or owner.
