Project Profile: Bicycle Hotel

bikehotel

The Bicycle Hotel & Casino is a popular gaming destination in Los Angeles with a newly added high-end boutique hotel. When the project team began searching for an HVAC system for the hotel, they knew exactly what they were looking for: a quiet system that could deliver superior performance in a 24-hour facility. They knew our Variable Refrigerant Flow (VRF) would meet their criteria.

Doug Lee, architect, Lee & Sakahara Architects, Irvine, California, was familiar with our VRF technology from previous installations. In addition to its quiet operation, our technology also offered fewer branch controllers – meaning fewer ceiling access panels – and a two-pipe system, helping to save on material and labor costs.

Even before completion, the system was receiving positive feedback. VRF’s small footprint and flexibility allowed a quick installation in a bustling location that never shuts down. “We wanted a system that would help facilitate and speed up that construction. We had the system installed in 50 days,” said Lee.

Most importantly, the system’s quiet operation leaves hotel guests in a comfortable, peaceful environment. It has even contributed to the hotel and casino earning recognitions like CALGreen and SoCal Edison certifications!

Green Retrofitting: The Future of the Past

As a society, we are increasingly demanding sustainability in all facets of life. The effect on the building industry has been staggering. Owners and managers of commercial buildings have quickly learned that going green can save on operating costs and can attract more, higher-paying tenants. As the U.S. Green Building Council recently learned, the result has been a dramatic increase in demand for green facilities.

Some of that demand is being met by new, high-performance buildings. To fully meet the mandate, however, the industry will need to take on a significant number of green commercial retrofit projects. The good news: The U.S. Energy Information Agency’s recent Commercial Buildings Energy Consumption Survey found that about half of America’s commercial buildings were built before 1980 – creating a wealth of buildings just waiting to get the green treatment.

The scope of each commercial retrofit will include meeting tenant requirements for features like rooftop gardens, recycling and composting programs, and green transportation options. The list of mechanical systems that engineers will be asked to update isn’t unexpected. It includes:

For all of these systems, the question will be what technology or product can help a project meet its client’s needs and budget, as well as today’s building codes. A frequent answer:  super-efficient, state-of-the-art technologies – the same ones that were once considered “alternative.”

Project Profile: Asbury United Methodist Church

The Asbury United Methodist Church (AUMC) in Harrisonburg, Virginia, has been welcoming guests through its doors for 228 years. Today, the church still offers religious services but also serves as a place for education and community activities. AUMC’s education and community wing totals 23,000 square feet of the building and quickly needed a long-term HVAC solution.

Pastor Bob Talbott and Bill Rees, AUMC’s chairman of the trustees, both agreed that the current HVAC system required too much maintenance, and that Variable Refrigerant Flow (VRF) was the perfect solution for the supplementary space. Rees said, “It was the efficiency and functionality that drew us to it – to be able to control individual rooms, to be able to schedule and change the temperature based on the comfort of the folks in the room.”

AUMC selected Blauch Brothers, Inc., Harrisonburg, to complete the project. Winston Rhodes, PE, design engineer, Blauch Brothers, felt Mitsubishi Electric was a wise choice. “Mitsubishi [Electric] was clearly the most field-proven; it has all the kinks worked out as the most mature product in the VRF line.”

Without going over budget, the installation was successful, and the result has been extremely positive for AUMC. The church now has the control and zoning abilities it wanted.

As Rees said, “The system has performed nicely given the variety of uses. Our education wing is used every day – morning, afternoon and evening. The big spaces are used, and the small classrooms are used. So it’s a variety of uses at a variety of times, and the Mitsubishi [Electric] system is performing very, very well.”

Maximizing Comfort in Health and Wellness Facilities

clinic

Healthcare Facilities Management magazine recently reported the success of some HVAC systems in health and wellness facilities. With stringent indoor air quality requirements, these facilities need systems that condition outside air, monitor and control humidity, filter air and provide ample ventilation. The article reported that beyond these measurable requirements, facility managers also want sustainable and energy-efficient systems. It also recognized a few manufacturers – including us – as meeting these needs.

Specifically, our latest Variable Refrigerant Flow (VRF) innovation, CITY MULTI® L-Generation Air-source technology, was recognized for its improvements in efficiency and its ability to maximize heat transfer. In regard to facility management, the magazine celebrated our Diamond Controls™ Solutions for its assistance in helping managers modify zone temperatures and observe building conditions, such as occupancy, CO2 levels, energy usage and humidity levels.

To learn more about how our VRF performs in health and wellness facilities, check out these case studies: Choctaw General Hospital and Grand Lake Mental Health Center.

LEEDing the Way

museum2

On September 24, 2016, the Smithsonian Institution will cut the red ribbon to its 19th museum. Taking the last vacant site on the National Mall in Washington, D.C., The National Museum of African American History and Culture houses over 36,000 artifacts telling stories about how African Americans contributed to the foundation of today’s society. We are deeply honored to be a part of this momentous occasion and this important landmark.

Lead designer David Adjaye and lead architect Philip Freelon designed the building by drawing inspiration from cultures such as the Greco-Romans and Africans. The well-recognized, bronze-colored lattice wraps the entire building but also allows natural sunlight to brighten the interior. Adjaye’s exterior design choice was just one factor that helped the building become the first among the Smithsonian museums to earn LEED® Gold certification. The building contains other systems contributing LEED points, including solar hot water panels on the roof, a geothermal groundwater system and our CITY MULTI® Variable Refrigerant Flow (VRF) zoning system.

To experience this historic opening and learn about history in a comfortable environment, check out the museum’s website to reserve free passes.

Project Profile: Sacramento Drill Tower

drilltower

The Sacramento Drill Tower, Sacramento, California, is an unusual building. A large water tank takes up two-thirds of the 9,476-square-foot, concrete facility. The other third is occupied by offices for the city’s firemen, administrators and IT personnel. For years, these occupants were cooled and heated by a four-pipe chilled-water and boiler system. When that system failed, the city installed our Variable Refrigerant Flow (VRF) technology. The result: immense energy savings and easy maintenance.

When the building’s old chilled-water compressor failed, Nghiem Nguyen, the mechanical maintenance supervisor for City of Sacramento Facility Maintenance turned to our systems. “I was fully impressed by VRF and Mitsubishi [Electric]. They were so far ahead of everybody else when it came to VRF. The engineering aspect and operational maintenance were really in place . . . I knew this would be a great application. It wouldn’t be hard to retrofit since we wouldn’t have to open up the walls to pull out old lines. The real selling feature, though, was the energy savings. I knew it was going to be huge for us.”

Ngyuen was correct. Comparing pre- and post-installation energy data shows that the system’s efficiency has led to a total energy savings (kBtu usage) of 50 percent, and a total cost savings of 19 percent. Money has also been saved on maintenance: “We’re saving so much money on service calls and maintenance calls. We probably have a tenth of the service calls we had before.”

The Sacramento Drill Tower project was so successful that it inspired the city to use VRF at two more facilities. To learn more, check out the case study.

Project Profile: The Willow School

NJ and NY premier Architectural & Interior Photography Studio Specializing in Interior Design, Aerial, Real Estate, Restaurant, and Business Photographer.

“How do you make a building like a tree?” That was the question Mark Biedron, co-founder, The Willow School (Willow), Gladstone, New Jersey, was trying to answer when he, his wife Gretchen and the team at Willow embarked on the Living Building Challenge (LBC). LBC is a standard requiring buildings to be 100 percent electric – often functioning at net-zero or net-positive energy usage. This was the goal for Willow’s new 20,000-square-foot Health, Wellness and Nutrition Center – and it was our very own VRF technology that helped achieve that goal.

Since a tree would use only sunlight, Willow produced energy with photovoltaic panels. That energy then fueled the school’s mechanical systems, like our VRF technology and Lossnay Energy Recovery Ventilators. The VRF units keep the school comfortable for little energy, while the Lossnay ERVs enable this new building to recover energy from exhaust air and simultaneously cool or heat outside ventilation air as it enters the building.

The result is a hugely efficient energy operation – a reflection of the school’s commitment to sustainability, and of the smart products and project design. “Every load was tracked and analyzed. Every amp and watt was accounted for. Nothing was missed,” said Vin Farese, Loring Consulting Engineers, Princeton, New Jersey. The success is evident: The school building performs more than 700 percent more efficiently than conventional educational facilities. Biedron is very proud of that fact: “It’s really the responsibility of the educational community to teach children how the planet works, why that’s important and how to use energy efficiently.”

To learn more about the efficiency at Willow – including how our customer service helped Willow meet certain LBC codes – check out the case study.
