The purpose of this Energy Addendum (Matrix) is to establish certain code requirements that address issues specific to this jurisdiction that are not already addressed in the currently adopted 2015 International Energy Conservation Code (IECC). These requirements include increased energy conservation measures to offset additional energy use and consumption in houses above a certain size or that contain large amounts of glazing. The Matrix also addresses energy upgrades in existing houses when feasible and removes certain exemptions found in the 2015 IECC. The Matrix also establishes certain minimum equipment efficiencies and renewable energy preparation requirements per Appendix RB of the 2015 IECC.
Section 101 Scope and Administration
Section 101.1 Scope All Residential and Commercial Residential (multi-family dwellings or the Residential portions of mixed use occupancy) buildings in Pitkin County shall be required to comply with the requirements of the Matrix as applicable.
Section 200 Definitions
Air Sealing (Leakage) The buildings thermal envelope shall be constructed to limit air leakage in accordance with the requirements of Section 402.4 (f) 2015 IECC
AFUE Annual Fuel Utilization Efficiency A measure of how efficiently your furnace can utilize its fuel. The more efficient your furnace, the more heat you will get per unit of fuel.
Commissioning Project commissioning is the process of assuring that all systems and components of a building or industrial plant are designed, installed, tested, operated, and maintained according to the operational requirements of the owner or final client.
Continuous Insulation (as defined by Section R202 2015 IECC)
ERI Energy Rating Index (as defined by Section 406.3 2015 IECC)
Glazing Windows, doors and skylights or other similar glass components
Home Energy Assessment (Home Energy Audit) A home energy audit is a service where the energy efficiency of a house is evaluated by a person using professional equipment (such as blower doors and infrared cameras), with the aim to suggest the best ways to improve energy efficiency in heating and cooling the house.
R-Value A measure of thermal resistance, or how well a material or series of materials resist the flow of heat. The R-value is the reciprocal of the U-factor.
Sustainable Construction Methods Using processes that are environmentally responsible and resourceefficient throughout a buildings construction.
Thermal Bridging A component, or assembly of components, in a building envelope through which heat is transferred at a substantially higher rate than through the surrounding envelop area.
U-Factor A measure of how well a material or series of materials conducts heat. U-factors for window and door assemblies are the reciprocal of the assembly R-value. The smaller the number, the less the heat flow.
Section 300 Application and Enforcement
Section 301 Submittal Requirements and Inspections 23
Section 301.2 Plan Submittal. Compliance with the Matrix shall be demonstrated by appropriate notations or details represented on the set of documents submitted to the Building Department for review, approval and issuance.
Section 301.2 Inspection Process. Compliance with the Matrix shall be demonstrated by review of the approved permit documents and field inspection of the indicated requirements.
