Mechanical, Electrical, & Lighting Design Services An Office with LEEDTTMM Accredited Professionals 40801 US Hwy 6 & 24, Suite 214, Eagle-Vail, CO 81620 Post Office Box 8489, Avon, CO 81620 phone: 970-748-8520 email: stan@aec-vail.com web: www.aec-vail.com July 5, 2017 – Update January 15, 2018 Roger Hall David Johnston Architects 119 South Spring St, Suite 203 Aspen, CO 81611 Re: Lot 7 Thunderbowl, Aspen, CO Dear Roger, This document is intended to show compliance of the new construction of the residence located at Lot 7 Thunderbowl in Aspen, Colorado with the 2015 International Energy Conservation Code (2015 IECC). We propose to use a prescriptive approach per sections 402.1-402.3 and 403.2.1 of the 2015 IECC. Project The project at 27 Fall Creek Road is the new construction of a residence with a floor area of approximately 8,900 sf plus a garage. For RREMP fees and heat load calculations, please refer to the Appendix. The heat load calculations are performed using the Carrier Hourly Analysis Program and provides a more detailed and accurate load than the Manual J heat load method. We have also provided equipment selections sheets in place of the Manual S selection process. Building Envelope The following table lists the mandatory minimum insulation and fenestration requirements for the project climate zone (7). All new assemblies will meet the following requirements. Fenestration U-factor Ceiling R-value Wood frame wall R-value Floor R-value Basement wall R-value Slab R-value Crawl Wall R-value Code Minimums 0.28 (1) 49 20+5(5) 38 (2) 15/19 (3) 10 (4) 15/19 (3) Notes: 1) Fenestration SHGC requirements do not apply in climate zone (7) 2) Or insulation sufficient to fill the framing cavity, R-19 minimum 3) R-15 continuous insulation on the interior or exterior or R-19 cavity insulation on the interior of the basement wall. Can be satisfied with R-13 cavity plus R-5 continuous. 4) 4 ft deep and R-15 edge insulation for heated slabs 5) Cavity + Continuous Insulation.

FT. FOOTPRINT 4 PUMP CONTROL WIRELESS OUTDOOR SENSOR CAPABLE Lochinvar.com 1/16/18 THE NEW 98% STANDARD Lochinvar re-defined the fire-tube boiler category with its KNIGHT® Wall-Mount and CREST® lines. For residential and light commercial applications, the FTXL™ adds models from 399,999 to 850,000 Btu/hr, and takes Lochinvar’s fire-tube technology to the next level. FTXL offers best-in-class AHRI Thermal Efficiency and footprints, plus remote connectivity that puts the SMART SYSTEM™ control at your fingertips, anywhere! REDUCE INSTALLATION COST WITH VARIABLE FLOW TECHNOLOGY FTXL can operate over a wide range of flow rates* with very low pressure drop. This permits installation of a “full flow” (variable primary) system eliminating the time and materials cost of primary/secondary piping, and pumps needed to maintain flow in a water-tube boiler. Variable flow also makes FTXL more flexible at handling frequent fluctuations in the system flow rate. *See back page for minimum and maximum flow rates by model. SMOOTH-RUNNING, MODULATING COMBUSTION FTXL boilers have a top-mounted, micrometal fiber burner, with a blower/gas valve assembly that drives heat energy downward, through stainless steel fire tubes, with exhaust venting through the bottom of the unit. With up to 10:1 modulation turndown, the burner automatically changes its firing rate as building heat loads vary. An FTX500 fires at its maximum 500,000 Btu/hr rate when heat load is highest, then gradually “turns down” to as low as 10% (50,000 Btu/hr) as load decreases. A modulating system runs smoothly and efficiently, without frequent on/off cycling. MINIMUM SUPPLY PRESSURE, INSTALLER-FRIENDLY FTXL operates with supply gas pressure as low as 4 inches water column. Negative Regulation draws gas into a pre-mix combustion system, instead of relying on utility pressure through the gas valve. The result is steady operation in low gas pressure systems or when peak demand occurs on gas supply. Automatic fan speed control fine-tunes the correct fuel/air ratio entering the burner, providing superior combustion throughout the entire operating range. 1/16/18 INTRODUCING BOILER PLANT CONTROL, FROM ANYWHERE. FTXL features the next generation of Lochinvar’s all-in-one SMART SYSTEM operating control with a re-designed multi-color LCD interface. SMART SYSTEM provides outstanding functionality, and can be integrated directly into a Building Automation System via ModBus and other communications protocols. And now, the CON·X·US mobile communication platform allows SMART SYSTEM to go where no other boiler has gone before.† CON·X·US provides the ability to monitor and manage multiple FTXL boiler plants without ever stepping into the mechanical room. CON·X·US will send alerts via text or e-mail notifying of changes in system status, and anytime, from anywhere, a user can check system status and re-program any boiler function. Once downloaded, the free CON·X·US mobile application allows for remote access to all SMART SYSTEM functions using any Internet-capable device. †CON·X·US control board sold separately. See back cover for a complete list of SMART SYSTEM features. ® REMOTE CONNECT ® REMOTE CONNECT 1/16/18 LOCH-N-LINK® EASY USB FLASH PROGRAMMING Use a USB drive to name, store and easily manage multiple existing proven parameter sets. Quickly upload them via the front panel port into the FTXL boiler, reducing installation and programming time by up to 30 minutes per boiler. WIRELESS OUTDOOR SENSOR Easy to install, greatly reduces time and materials cost for running sensor wire from standard outdoor temperature sensor to boiler control. Approximate range 2,000 feet line-of-sight. ENHANCED MULTI-COLOR LCD INTERFACE normal lockout maintenance HOW 98% TRANSLATES INTO FTXL SAVINGS Even when compared to other condensing boilers, the FTXL fire-tube combustion system will produce significant fuel cost savings. Here are three comparisons, based on building load of approximately 19,000 therms/ year, at a cost of $1.09 per therm of natural gas. Fuel savings is based on a heating load of 19,000 therms per year being supplied by an 82% efficient boiler at the DOE National average for natural gas of $1.09. 3 - Year Fuel Savings $14,000 $12,000 SAVES $12,400 $10,000 $8,000 $6,000 $4,000 $2,000 $0 EFFICIENCY 85%87%94%FTXL 98% 1/16/18 THE SMALLEST FOOTPRINT, EASY TO INSTALL & SERVICE FTXL can be installed with zero clearance on the left and right, and the boiler’s installed footprint is just 6.2 sq. ft. All water, gas and vent connections are in the back of the unit. A hinged top opens for easy access to components and the front panel is easily removed using no tools. FLEXIBLE VENTING OPTIONS FTXL offers 6 venting options, and permits direct-vent air intake and exhaust runs up to 100 equivalent feet, using PVC, CPVC, polypropylene or stainless steel pipe. Plus multiple units can be common-vented to reduce time and materials costs. PEACE OF MIND, WHEN IT MATTERS MOST Up to eight FTXL boilers can be sequenced using a 2-wire daisy-chain connection. Cascade sequencing can be programmed for “Lead-Lag” or “Efficiency Optimized” operation. With Lead-Lag operation, one lead boiler modulates to capacity on demand. As load increases, the system then cascades to additional lag boilers in sequence. The first-on role shifts daily, distributing equal runtimes to each unit. In an Efficiency Optimized system, all boilers fire and modulate simultaneously at the same BTU/hr input rates, maximizing thermal efficiency. If the lead boiler is turned off for maintenance, Cascade Redundancy automatically shifts the lead role to the second sequenced boiler. Peace of mind comes from knowing the system will still function with no downtime until the original lead boiler is back online. 1 2 3 4 5 6 Room Air Vertical Room Air Sidewall Direct Vent Common Vent Direct-Vent Vertical Vertical w/Sidewall Air TO LEARN MORE, LOG ON TO WWW.FTXLBOILER.COM TODAY! 1/16/18 53-1/2" H F 26-1/4"2-1/2"22-1/2"A 65-1/2" 2-1/2" G 40" 9-3/4" C A B D E 26-1/4" Air Inlet Electrical Connections Water Outlet Water Inlet Flue Connection Condensate Connection Gas Connection FTXL™ Boiler Dimensions and Specifications* FTXE-01 (Reprint 5/16) 10M - PDP - © Lochinvar, LLC - 12/16 - Printed in U.S.A. iPhone and iPod touch are trademarks of Apple Inc., registered in the U.S. and other countries.
