  1. MECHANICAL ASPECTS OF MICHIGAN UNIFORM ENERGY CODE MIAM DOHERTY INN 09-5-2011 CLAIRE, MICHIGAN MARK RILEY

  2. PRESENTATION DIVIDED INTO TWO PARTS • RESIDENTIAL R-2, R3, R4, Less than 4 stories. • COMMERCIAL – except low rise residential

  3. RESIDENTIAL CODE • Based on chapter 4 0f 2009 International Energy code modified to Michigan Uniform Energy code • MUEC is 36 pages while is 79 pages

  4. Structure of the IECC • Chapter 1 Administrative • Chapter 2 Definitions • Chapter 3 Climate Zones • Chapter 4 Residential Energy Efficiency • Chapter 5 Commercial Energy Efficiency • Chapter 6 Referenced Standards Residential Chapter

  5. 401.3 CERTIFICATE • POSTED ON ELECTRICAL PANEL • CAN’T COVER REQUIRED LABELS ON PANEL • LISTS TYPES EFFICIENCIES OF HVAC & HOT WATER HEATER

  6. Table 402.4.2 concerns • Shafts, Penetrations duct shafts, B Vent must be sealed. • HVAC register boots outside walls and floors over unconitioned areas. • Fireplace walls – Air barrier required.

  7. HOMEWORK WAS NOT DONE ON THIS CODE! CONFLICT 403.2 – 1601.4.5 item 4 2009 MRC 403.7 REFERENCES 503 -504 DOES NOT EXIST SECTION 403.4 CIRCULATING HOT WATER SERVICE SYSTEM REFERENCES HVAC EQUIPMENT! THIS CODE IS MESSED UP

  8. MANDATORY VS. PRESCRIPTIVE SECTION 403 • 2 METHODS COMPLIANCE • SECTION 403 ONLY REFERENCES 403.2.1 FOR PRESCRIPTIVE • DUCT INSULATION SEE SECTION 405.2 • PRESCRIPTIVE CAN ALSO USE TOTAL U/A ALTERNATIVE RESCHECK.

  9. CONTROLS 403.3 • PROGRAMMABLE THERMOSTAT • INITIALLY PROGRAMED • HEAT PUMP SUPPLEMENTARY

  10. Ducts 403.2 – INSULATION & SEALING • R-8 SUPPLY IN ATTIC ALL OTHER R-6 (CONFLICTS) WITH 2009 MRC) • DUCT SEALING PER MRC M1601.4.1 • AIR DUCT TESTING DELETED

  11. PIPE INSULATION 403.3 • 403.3 Mechanical system piping insulation (Mandatory). Mechanical system piping capable of carrying fluids above 105°F or below 55°F shall be insulated to a minimum of R-3. • Exceptions – HVAC equipment & run out piping 4 feet from valve.

  12. PIPE INSULATION 403.4 • Circulating hot water systems (Mandatory). All circulating service hot water piping shall be insulated to at least R-2. Circulating hot water systems shall include an automatic or readily accessible manual switch that can turn off the hot water circulating pump when the system is not in use. • Exception does not make sense.

  13. EXHAUST FAN DAMPERS 403.5 EXHAUST FANS REQUIRE BACKDRAFT DAMPERS MOTORIZED OR GRAVITY ALLOWED

  14. EQUIPMENT SIZING 403.6 • Additional requirements for equipment sizing are included by an inspection for compliance with the Michigan Residential Code. M1401.3

  15. SYSTEMS SERVING MULTIPLE RESIDENCES 403.7 • For systems serving multiple dwelling units documentation has been submitted demonstrating compliance with 2009 IECC Commercial • Building Mechanical and/or Service Water Heating (Sections 503 and 504). • No code sections in the book!

  16. Swimming Pools:403.9 • Heated swimming pools have an on/off heater switch. Pool heaters operating on natural gas or LPG have an electronic pilot light. Timer switches on pool heaters and pumps are present. • Exceptions: • Where public health standards require continuous pump operation. Where pumps operate within solar- and/or waste-heat-recovery systems. • Heated swimming pools have a cover on or at the water surface. For pools heated over 90 degrees F the cover has a minimum insulation value of R-12.

  17. SIMULATED PERFORMANCE ALTERNATIVE SECTION 405 • Mandatory requirements. Compliance with this section • requires that the mandatory provisions identified in Section 401.2 be met. • All supply and return ducts not completelyinside the building thermal envelope shall be insulated to a minimum of R-6. • EnergyPlus Energy Simulation Software

  18. COMMERCIAL ENERGY CODE Rule 1087. Rules governing the energy efficiency for the design and construction of buildings and structures, not including residential buildings, shall be those contained in the international energy conservation code, 2009 edition, section 501.1 and the ASHRAE energy standard for buildings except low-rise residential buildings, ANSI/ASHRAE/IESNA standard 90.1-2007 (hereafter the standard), including appendices A, B, C, and D.
