Breckenridge’s Arts District combines historic charm with amenities such as dining, shopping, and art studios, galleries, and performance spaces to bring arts and entertainment to locals and visitors of this former mining town. For development of the District, 360 Engineering provided mechanical and plumbing engineering design and construction administration services for a project that included a 2,600-square-foot ceramic studio, the Robert Whyte House (1,083 sf), Burro Barn (500 sf), Randall Barn (700 sf), and 1,000 square feet of flexible-use studio space. The team first reviewed the area’s existing mechanical and plumbing systems and then engineered construction drawings for new replacement systems. In addition, a study for a potential addition/renovation of the existing Breckenridge Theater building was conducted.
Constructed in the 1930s to honor George Rogers Clark, this circular granite building consists of a 40-ft. high rotunda with a glass ceiling. The interior features seven historically significant murals, along with three of Clark’s quotations. To address a failing mechanical system, 360 Engineering provided new mechanical and electrical systems. The granite walls posed a unique challenge, as they did not allow new chases to be created for routing conduits, pipe, or ductwork. Several options were explored including replacement of the existing steam boilers and reuse of the existing steam lines, installation of new high-efficiency heating water boilers and reuse of the existing steam lines as hydronic lines, converting the building to electrical power, or a new geothermal system. With the design team’s input on the pros and cons of each option, the client decided on a new geothermal system, which entailed creation of 18 300-ft. deep boreholes, which were installed in an archaeologically clear area south of the memorial.
Utah’s Natural Bridges National Monument features three natural rock bridges formed by erosion caused by water flowing through the canyons. 360 Engineering is designing a new mechanical system for the existing onsite pump house, supporting the replacement of common domestic and fire protection piping, and specifying equipment for the replacement of the booster pumps and fire pump.
Rocky Mountain National Park’s Beaver Meadows Visitor Center, built in 1967, was designed by Frank Lloyd Wright’s firm, Taliesin Associated Architects, following his death. The park’s main visitor center, this unique structure is undergoing a full mechanical renovation including design and installation of a new four-pipe fan coil system and the refurbishment of existing ventilation systems. All work must be completed without compromising the building’s original architectural design.
One of the town’s several National Historic Landmarks, the 1909 Breckenridge Schoolhouse underwent a two-year comprehensive rehabilitation to become the Breckenridge Grand Vacations Community Center and Summit County South Branch Library. The 26,000-square-foot space features a new 160-seat feature film theater, a community conference space, a library with multipurpose meeting spaces, expanded reading areas, state-of-the-art technology, and coffee shop, and other amenities. During early design, 360 Engineering provided cost-saving mechanical engineering consulting to the Town of Breckenridge. Based on research and an evaluation of local climate data, the team determined that a full mechanical cooling system was not required, and that a passive cooling system was the most suitable solution. This resulted in a positive impact on the Town’s budget and allowed them to maximize return for their investment in other areas of the building. 360 also designed a new facility-wide mechanical system to accommodate the building’s changed use.
Scotts Bluff, a stone formation that rises 800 ft. above the North Platte River in Nebraska, has long served as a landmark for travelers — from Native Americans to pioneers on the famed Oregon, California, and Mormon Trails to people today. Located inside the 3,000-acre Scotts Bluff National Monument park, the historic Oregon Trail Museum and Visitor Center, comprising several structures built in phases from 1935 – 1949, needed renovation and system upgrades. 360 Engineering designed new mechanical and plumbing systems for the main visitor center and an additional building. To preserve the facility’s original design intent, the existing in-wall ducts and grills were incorporated into a new, energy-efficient VRF (Variable Refrigerant Flow) HVAC system with energy recovery ventilation.
A historic 211-room hotel built in 1915, Many Glacier Hotel is the primary visitor service facility for the east side of Glacier National Park in Montana. For a renovation encompassing 31,000 square feet of the south half of the hotel, including approximately 80 guest rooms, the design team’s scope of work included the replacement of fire suppression, fire alarm, plumbing, electrical, and ventilation systems. All work complied with National Park Service requirements for quality control, sustainability, and integrated design principles.
Originally built in 1891, St. Barnabas Episcopal Church has undergone several renovations and additions over the years. Most recently in 2016, there was a full remodel of the parish hall, including classrooms, office and work space, and a commercial kitchen, plus an opening up of space between the existing sanctuary and Fellowship Hall to accommodate the growing congregation. 360 Engineering designed complete mechanical and plumbing systems for this renovation, which now provides a commercial kitchen for special events and outreach ministries, and updated HVAC ventilation which offers better cooling/heating options for the church’s offices and classrooms. All renovations were complete in time for 2017 Doors Open Denver, an annual event that offers tours of select public and private architectural gems.
Metro Caring, a not-for-profit hunger relief organization that provides urgent food assistance and related services to individuals and families in need, had outgrown its facility. Conditions were cramped and parking was limited. A new ground-up 15,000-square-foot facility constructed on the existing site and an adjacent vacant lot consists of a lobby/reception area, a welcome center, client care offices, administrative offices, a boardroom, a nutrition center with kitchen, and a “healthy living” space featuring a Client Choice Market that teaches healthy grocery shopping. The market is completely stocked with shelving, reach-in coolers, and freezers, and has support areas for processing, warehousing, and a loading dock. Multiple mechanical systems were evaluated, including evaporative cooling and mechanical cooling with either change-over bypass or VAV operation before deciding on a combination of VAV and constant volume. To meet a strict budget while limiting onsite water use, plumbing fixtures were specified at low flow rates to achieve a smaller standard tap size.
Located in Denver’s Lower Downtown (LoDo) area, the Alliance Center is a six-story, 40,000-square-foot office building originally constructed as a warehouse in 1908. More than 100 years later, this historic structure was renovated into a sustainable, multi-tenant facility by its owner, The Alliance for Sustainable Colorado (the Alliance). With building improvements including a new digitally controlled HVAC system, energy-efficient fixtures and appliances, a lighting control system, translucent wall panels, sun shades, and a rooftop photovoltaic (PV) array, the two-year project transformed The Alliance Center into an extremely energy-efficient building. All onsite combustion of fossil fuels was eliminated, including the use of natural gas for heating, in favor of using solar or gridded electricity to meet all power needs.
To further decrease their carbon footprint, the Alliance launched its “DC project.” Devices such as computers, office equipment, and consumer electronics consume DC (direct current) power, generated by converting grid-supplied AC (alternating current) electricity to DC, an inefficient process. After exploring several options, 360 Engineering designed a system with the capacity to accept input from up to four different energy sources in addition to gridded electricity. By allowing the use of more solar (PV), wind, and any future clean energy technologies, this approach drastically lowered the Alliance Center’s reliance on the grid and further reduced its CO2 emission. During the project, 360 also collaborated with manufacturers to convert existing HVAC equipment to DC input, an effort that resulted in a research grant from Colorado State University to further study the potential energy savings of such HVAC AC-to-DC power conversions.
The facility has received several LEED certifications including Existing Building Operations and Maintenance LEED Gold, Commercial Interior LEED Silver, and Dynamic Plaque LEED Gold. It was the first facility in Colorado and fifth in the world to recertify based on ongoing building performance evaluation.
