All monies collected pursuant to this section shall be recorded in a separate fund and shall be spent in accordance with a joint resolution by the Aspen City Council and Pitkin County Board of County Commissioners.

Section 103 Credits for on-site renewable energy. This RREMP payment option is voluntary. Applicants interested in exterior energy use systems can alternatively choose to produce on-site renewable energy (Section 301) with solar photovoltaics and/or solar hot water or micro-hydro. The energy efficient technology of ground source heat pumps is also permitted for supplemental on-site energy.

SECTION 104 PRE-EXISTING SYSTEMS

Pre-existing snowmelt, pools or spas Installed prior to Aspen Pitkin Energy Conservation Code (APECC adopted in 1995) which are being replaced, overhauled or renovated qualify for exterior energy credit. This credit can only be applied towards an installation of exterior energy on the same parcel. The calculation of the credit shall be based on section 301. The maximum allowable replacement credit shall be 6000 square feet of snowmelt (or 240,000,000 BTU’s). The replacement credit may be applied to other exterior energy consumption. Systems installed after the adoption of APECC 1995 without permit approval are not eligible for replacement credit and are subject to all applicable fees.

Section 105 - Residential repairs. Repairs to building components, systems, or equipment which do not increase their pre-existing energy consumption need not comply with RREMP. All replacement mechanical equipment shall be Energy Star© rated.

Section 106 Residential Renewable Energy Mitigation Program (RREMP) for houses 5,000 square feet and more. A new residence 5,000 sq ft or more in area (as defined by the building code), or a residence receiving an addition which brings the area of the residence to 5,000 sq ft or more, is required to offset a portion of its fossil fuel energy consumption through the use of on-site renewable energy or through a fee payment to REMP. Renewable energy systems installed for this requirement do not qualify for credit for exterior energy use.

Section 301.1 Photovoltaic Systems – On-site renewable credit shall be calculated as $6,241.20 per 1 kilowatt of the system design. Solar electric (photovoltaic) systems tied to the electric grid, are eligible for on-site renewable credit. Systems must be sited, oriented and installed for solar electric panels to supply at least 90% of rated capacity of the installed KW. System designer/installer must be certified by COSEIA (Colorado Solar Energy Industries Association) or NABCEP, (North American Board of Certified Energy Practitioners).

Section 301.2 Solar Hot Water - On-site renewable credit shall be calculated as $224.65 per 1 square foot of the system design. The size of solar hot water systems is limited to 500 square feet of collector area.

Section 301.3 Ground Source Heat Pump - On-site renewable credit shall be calculated as $6.84 per 100,000 BTU per year of the system design. In order to use a GSHP for on-site renewable credit the GSHP system must supply at least 20% of the peak load for heating the house and all the exterior energy uses. Each ground source heat pump system shall be tested and balanced and the design engineer shall certify in writing that it meets a design coefficient of performance of 3.0 inclusive of source pump power.

The ground loop system must be designed by a CGD (Certified GeoExchange Designer certified by the Association of Energy Engineers) or a professional engineer with IGSHPA (International Ground Source Heat Pump Association). The mechanical system must be installed by a certified IGSHPA contractor.

SECTION 501 Governmental Renewable Energy Mitigation Program (GREMP)

Local, State and Federal Government Buildings and Structures may be exempted from mitigation payments and offsets defined previously in this code for a percentage of the requested snowmelt when there is a demonstrated risk to public safety related to snow and ice removal.

The following items and any related documentation will be reviewed and evaluated to determine the potential exemption. A percentage of exempted area will be determined and any remaining requested snowmelt will need to be paid for or mitigated in the typical format. Upon receommendation by the Chief Building Official, a formal request will be compiled by the applicant and presented to the Board of County Commissioners for final approval at a regularly scheduled meeting.

501.1 An application for review and approval would include the following:

1. Demonstration and declaration that typical mitigation methods were researched and proven not feasible.

2. Demonstration that the public service being service provided by the entity applying offsets the energy consumption being requested in this application including any cumulative offset exemption requests for REMP mitigation.

3. Demonstration of safety risk to the General Public if exterior snowmelt is not installed including:

• a. 2. Providing the ratio of total paved area vs. Snowmelted pavement
• b. Illustrating that the project minimizes the total amount of exterior energy used; and
• c. The installation of snowmelt only in critical public safety areas.

4. Demonstration that BTU’s saved through other means (existing equipment upgrades, envelope improvements, or other energy saving measures) translate to mitigation BTU’s for snowmelt credit. Examples include:

• a. Hybrids
• b. Wind Poser
• c. Hydro-Electric
• d. Waste Oil Boilers
• e. Pellet Boilers

5. Demonstration that offsite mitigation alternatives have been considered at other offsite locations within Pitkin County for the installation of typical mitigation methods.

• a. Typical Ground Source Heat Pump, Solar, or PhotoVoltaic methods that are not feasible on site could be installed at a more feasible location
