The 15500 W. Colfax Avenue building was built in 1968 and formerly belonged to Rick’s ENCO. Rick's ENCO was both a gas station and a car maintenance & repair shop. ENCO was the secondary retail brand name for Humble Oil Corporation products from 1960 to 1977. At the grand opening of Rick’s ENCO, they advertised giving away 10,000 S&H green stamps which were redeemable for products in the Sperry & Hutchinson rewards catalogs that were popular at the time. The repair shop was proud to offer their customers the once cutting-edge Snap-On Auto-Check System, which could electronically analyze your car’s systems and report on mechanical issues and locations. The station was open 24 hours a day, 7 days a week to always provide for their customers and community. Rick's ENCO was eventually bought and renamed Whitey's ENCO. Whitey’s ENCO advertised their grand opening by offering customers a 6-pack of Sprite with the purchase of 8 gallons of gas or an oil change. They boasted having the latest equipment and the finest in ENCO service until their close.

U-Haul acquired the iconic ENCO gas station in 1976 for adaptive reuse into a truck sharing and moving retail store. Adaptive reuse building conversions allow U-Haul to promote infill development to meet citizens’ needs while preserving the natural resources and land normally required for new construction. Adaptive reuse also allows resources to be focused on integrating environmentally thoughtful features into the existing building rather than creating waste in the form of demolition and using valuable resources for new construction.

Serving U-Haul customers since 1976, this facility was built through adaptive reuse of an abandoned building. Adaptive reuse promotes infill development in an effort to strengthen communities, with the following benefits achieved at this site: 

• 49.4 tons of metal manufacturing & transportation prevented 
• 259.3 tons of new concrete pours avoided 
• 312.7 tons of construction and demolition debris prevented 

Energy-efficiency and waste-reduction programs at this facility provide the following estimated benefits each year for the Golden community: 

• 302,696 lbs greenhouse gas emissions prevented 

• 

  Steel Production 49 tons (45 tonnes) of steel manufacturing and delivery saved to date

• 

  Concrete 259 tons (235 tonnes) of new concrete pours avoided to date

• 

  Emissions 302,696 lbs (137,302 kgs) of greenhouse gas emissions prevented

• 

  Landfill Debris 313 lbs (142 kgs) of construction debris prevented
