2. Exterior pools

3. Exterior hot tubs and spas

4. Permanent natural gas or electric systems for heating outdoor commercial spaces.

C410.1 On-site renewable credits.

Credits for renewable energy production will be calculated and applied per "Breckenridge REMP Calculation Sheet" for energy generated on-site. Renewable energy methods listed in the calculator include: solar photovoltaic, solar thermal, ground source heat pumps, hydroelectric and wind power. Provision for alternative method calculations is also provided, but it will require specific review and approval by the Building Official.

C410.2 Snowmelt systems.

1. R-10 insulation shall be installed under all areas to be snowmelted.

2. Required snowmelt controls. All systems are required to have automated controls to limit operation to when moisture is present, outdoor air temperature is below 40F and above 20F, and the slab temperature sensing. Idling of commercial slabs is allowed where public safety is a factor.

C411

A permit shall not be valid until all fees as in effect at the time of permit submittal are paid in full, or the renewable energy system is proposed for on-site credit. Nor shall a change order to the permit be released until the additional fees, if any, have been paid. REMP compliance will be verified at Certificate of Occupancy or Certificate of Completion according to the proposed plans. C.O. can be withheld if the project is non-compliant.

C412 Pre-existing systems.

Pre-existing systems, for which a prior permit was applied for and granted prior to the effective date of this code, are exempt from this program. Additions or expansions of existing systems that require a permit will require compliance with this above code program.

Pre-existing systems for which a prior REMP payment was paid and which seek to be replaced shall receive a pro-rated credit calculated by the number of years since prior REMP payment divided by 20 years. For example, a REMP payment made for a system permitted 10 years prior to the current replacement being sought will receive credit for ½ of the prior REMP payment and that amount shall be deducted from the REMP payment owed on the replacement. For renewable systems installed on site, full credit will be given for up to 20 years after the date of installation. Credits will only be applied to properly permitted and functioning systems within the scope of the adopted Energy Code and applicable Mechanical and Electrical Codes. Systems installed prior to 20 years before the date of permit application are not eligible for pro-ration of system credits.

Upgrades to existing mechanical equipment (boilers, heat pumps, HVAC equipment, etc.) or renewable energy systems will not require submittal to the REMP program.

Residential outdoor natural gas fireplaces, firepits, and firetables shall include timers required to limit the run time of the system. Controls and switching shall be configured so as not to allow continuous operation.

R409.1 Electric heat tape controls.

Electric roof and gutter deicing systems shall include either automatic controls capable of shutting off the system when outdoor temperature is above 40F and below 25F, and which limit the use of the system to daylight hours by means of a programmable timer or automated clock, or moisture detection sensors.

R410 Renewable energy mitigation payment.

A permit shall not be valid until all fees as in effect at the time of permit submittal are paid in full, or the renewable energy system is proposed for on-site credit. Nor shall a change order to the permit be released until the additional fees, if any, have been paid. REMP compliance will be verified at Certificate of Occupancy or Certificate of Completion according to the proposed plans. C.O. can be withheld if the project is non-compliant.

R411 Pre-existing systems.

Pre-existing systems, for which a prior permit was applied for and granted prior to the effective date of this code are exempt from this program. Additions or expansions of existing systems that require a permit will require compliance with this above code program.

Pre-existing systems for which a prior REMP payment was paid and which seek to be replaced shall receive a pro-rated credit calculated by the number of years since prior REMP payment divided by 20 years. For example, a REMP payment made for a system permitted 10 years prior to the current replacement being sought will receive credit for ½ of the prior REMP payment and that amount shall be deducted from the REMP payment owed on the replacement. For renewable systems installed on site, full credit will be given for up to 20 years after the date of installation. Credits will only be applied to properly permitted and functioning systems within the scope of the adopted Energy Code and applicable Mechanical and Electrical Codes. Systems installed prior to 20 years before the date of permit application are not eligible for pro-ration of system credits.

Upgrades to existing mechanical equipment (boilers, heat pumps, HVAC equipment, etc.) or renewable energy systems will not require submittal to the REMP program.

R412 Solar photovoltaic systems.

System designer and installer must be certified by Colorado Solar Energy Industries Association (COSEIA) or North American Board of Certified Energy Practitioners (NABCEP), or a licensed Professional Engineer in the State of Colorado.

R412.1 Solar thermal.

The size of solar hot water systems is limited to 500 square feet of collector area absent approval by the Building Official. Systems larger than this limit will be considered, but will require documentation showing year-round utilization of the system.

R412.2 Ground source heat pumps.

In order to use ground source heat pumps for on-site renewable credit, the GSHP system must supply at least 20% of the peak load for heating all the exterior energy uses. Each GSHP shall be tested and balanced and the design engineer shall certify in writing that it meets or exceeds a design coefficient of performance of 3.0 inclusion of source pump power. Design conditions for determining COP will be 30F ground loop temperature measured at the GSHP inlet, and 110F GSHP load side outlet.
