Sixty-one Acres of LED Lighting will reduce garage energy-use by 80 percent; Entire property by 7 percent

Duane Tilden‘s insight:

>LED technology is one of the highest performing, currently available methods of lighting. Energy savings of 50 to 80 percent are common when compared to the lamps that are typically used in garages. LED lamps also have much longer operating lives, resulting in fewer materials and transportation resources needed over time. The MGM Grand Detroit LED retrofit, will save enough electricity to power more than 350 average homes per year. […]

Earlier this year, the company initiated a program to install 1,600 induction technology lighting fixtures covering 160 acres of open lot parking area at its resorts in Las Vegas. These lamps are ideal for the hot Las Vegas climate and will have an operating life of up to 20 years. An estimated 2.7 million kWh will be saved annually following the project’s completion.

Additionally, MGM Resorts recently announced the planned installation of one of the largest rooftop solar photovoltaic arrays in the world at the Mandalay Bay Resort Convention Center. The 6.2-megawatt installation will be MGM Resorts’ first commercial solar project in the United States and will generate enough electricity to power the equivalent of 1,000 homes.<

Creating Value: Energy Retrofits for Buildings

See on Scoop.itGreen & Sustainable News

Buildings in the U.S. consume[…] 42 percent of the nation’s primary energy and 72 percent of its electricity. Much of that energy is needlessly wasted through inefficient design and operation.

Duane Tilden‘s insight:

>Rather than examine energy costs in isolation, our approach assesses how energy and sustainability improvements add value to all parts of a property or company. This approach is not revolutionary, but rather more comprehensive, applying industry-accepted valuation methods to the full set of retrofit value contributions, including saved energy costs, health and productivity benefits, reputation and leadership, and risk reduction.

Energy investment (and resultant property outcomes) should be treated as one of many factors that influence value, including location, tenant mix, quality of design, and more. Evaluating retrofits within the broader context of property/company value enables a logical, defensible calculation and assessment of a deep retrofit’s relative contribution to value. Previous attempts to value energy retrofits have ignored retrofits’ value contributions and overlooked standard approaches to valuing properties and companies.<

Wireless Transmission of Energy in Buildings – Building Automation

See on Scoop.itGreen Building Operations – Systems & Controls, Maintenance & Commissioning

Energy harvesting wireless technology becomes more attractive for OEMs as a basis technology for products and solutions that contribute to a building’s efficient energy management. The wireless modules gain their power from the surrounding environment…

Duane Tilden‘s insight:

>Energy harvesting technology enables batteryless automation devices and systems to make buildings more energy-efficient based on sustainable, resource-saving technologies that eliminate the need for batteries. […]

In a complex commercial building scenario, EnOcean Link can be implemented on a central device, like a control server, which controls the whole building, holds the automation intelligence, and can be physically located outside the building (in the cloud). Several gateways in the building record radio telegrams from thousands of distributed batteryless wireless sensors and relay receivers, and send back information or command data when needed. These gateways are connected to the control server by a backbone, which does not have to be based on EnOcean radio, or even be wireless. The middleware, located in the central unit, interprets all telegrams received by the gateways and provides them to the automation system.

High energy efficiency goals demand flexible automation systems for all kind of buildings that cover several areas. This particularly affects retrofit projects, where the intelligent control of energy consumption is the key factor for a building’s improved energy and carbon footprint. Energy harvesting wireless technology fulfills the demands for today’s and tomorrow’s automation and energy management systems. […]<

Innovative Empire State Building Program Saves Millions, Establishes New Energy Efficiency Model Nationwide

See on Scoop.itGreen Building Operations – Systems & Controls, Maintenance & Commissioning

/PRNewswire/ — The innovative energy efficiency program at the Empire State Building has exceeded guaranteed energy savings for the second year in a row, saving $2.3 million and providing a new model for building retrofits that is now being rolled…

Duane Tilden‘s insight:

>”The success from the Empire State Building retrofit project further demonstrates that thoughtfully applied energy-efficiency investments can deliver unparalleled returns through a combination of lower energy, lower operating costs, and increased building valuation,” said Iain Campbell, vice president, Global Energy and WorkPlace Solutions, Johnson Controls Building Efficiency.  “When implemented under a performance contract, the energy savings are guaranteed, ensuring a no-risk investment and a smart business decision.”

The retrofit has attracted new Empire State Building tenants over the past two years, including LinkedIn, Skanska, LF USA, Coty Inc., the Federal Deposit Insurance Corp., and Shutterstock.  These tenants sought space that reflected their sustainability values, provided more comfort for employees, and allowed them to monitor and control their energy use.

“The Empire State Building project has conclusively proven the business case for deep energy retrofits of any building,” said Raymond Quartararo, international director at Jones Lang LaSalle.  “We have consistently surpassed annual projected energy savings through a process that is very transparent, quantitatively intense and internationally approved.  The overwhelming majority of people want to do their part to reduce energy usage while delivering economic returns and occupying an environmentally responsible building.”<
