Study Finds Care Home Falls Reduced 43% By Changing Light Spectrum & Intensity

The Journal of Post-Acute and Long-Term Care Medicine (JAMDA) recently published a research study showing long-term care facility falls were reduced 43% by changing light spectrum and intensity throughout the day for residents.

The Journal of Post-Acute and Long-Term Care Medicine (JAMDA) recently published a research study showing long-term care facility falls were reduced 43% by changing light spectrum and intensity throughout the day for residents. In four long-term care homes totaling 758 residents, investigators at Brigham and Women’s Hospital, led by Shadab Rahman, Ph.D., MPH, and Leilah Grant, Ph.D., of the Division of Sleep and Circadian Disorders, studied whether changing the intensity and spectrum of lighting across the day — which impacts neurocognitive processes such as alertness, mood and sleep — can reduce the rate of falls in elderly care-home residents.

In the homes, specifically, the short-wavelength (blue) content of ambient lighting was changed dynamically across the day and night at two sites, with fall rates at these sites then compared to the fall rates from the two other control sites, where the intensity and spectrum were fixed throughout the day and night. Overall, the researchers found a 43% reduction in the rate of falls for those who were exposed to the dynamic lighting versus those who were not.

“The ability to significantly reduce the rate of falls in long-term, care-home residents by implementing a relatively low-cost, passive, environmental intervention such as changing the spectrum and intensity of lighting throughout the day as a preventative strategy has major implications for improving health and well-being in this at-risk population,” said Rahman, the corresponding author of the study.

Falls are the leading cause of injury-related death for older adults (age 65+) in America. Since current interventions to reduce falls are multifactorial and require significant time and resources, pushes have been made to find alternative low-cost and low-burden solutions.

“The Why” of Toggled iQ Networked Lighting Controls

In July, I wrote an article about a LightFair product demonstration that I received from Toggled, of their new wireless smart lighting platform, Toggled iQ. In that story, I focused on the various components (sensors, controllers, smart TLEDs, etc.), and the performance capabilities of those components.

What I didn’t cover was the question of why invest the additional time and money in a wireless networked lighting control system, like Toggled iQ.

What I didn’t cover was the question of why invest the additional time and money in a wireless networked lighting control system like Toggled iQ.

ENERGY MANAGEMENT

Converting a building from fluorescent to LED lighting can save up to 60% in lighting energy savings. Adding additional layers such as controls and back-end data analytics can add another 20% in energy savings.

Implementation of available Toggled iQ analytics capabilities allows users to manage and actively engage in improving their facilities’ energy efficiency. Device sensors provide data to Toggled iQ analytics tools which help identify areas that may be underperforming from an efficiency standpoint or flag areas that may not be used as often as originally thought – allowing for future efficiency adjustments.

OCCUPANT EXPERIENCE

By providing an optimal occupant experience, the Toggled iQ smart building platform can increase overall tenant satisfaction and can improve long-term tenant retention. Everything from lighting to HVAC can be customized and controlled in real-time, whether it be a single fixture, room, building or campus, all from the Toggled iQ mobile app. The building can be controlled by the organization or an individual.

PREDICTIVE MAINTENANCE

Predicting the remaining useful life of a building asset based on real-time data provided by Toggled iQ Analytics allows organizations to create, manage, and optimize maintenance schedules.

Toggled iQ Analytics provides multiple tools to help identify potential signs of deterioration, anomalies, and actual equipment performance issues in real-time. Collected data allows for the development of predictive maintenance schedules, which ensures assets continue to work at their optimal levels for as long as possible. Real-time data and predictive maintenance schedules also help to reduce labor costs associated sending crews out for maintenance that may not have been necessary.

WORKER SAFETY & PRODUCTIVITY

Maintaining clean building spaces will be key for those returning to work, post-pandemic. Part of that maintenance includes air quality. Toggled iQ devices can monitor and optimize air quality.

Providing quality lighting environments is also important. Toggled iQ lets end users tweak and tailor their lighting environment to make their workspaces more pleasant, efficient, and productive.

Flexible in-person workspaces can enhance collaboration and communication at work. Building owners and corporate leaders can develop their own unique workspaces that align to their organizational culture and environment. The control system can change room configurations in seconds, with the mobile app.

SPACE UTILITIZATION

Uncertainty in the pandemic has made it difficult for building facility professionals to optimize their spaces without wasting resources. Building data collection, utilizing Toggled iQ sensors and devices, combined with Toggled iQ Analytics enables building owners and facility managers to make informed office space utilization decisions.

The platform is capable of continuous monitoring of employees’ workspace usage and overall real estate utilization. Based on real-time data, facility managers can now better understand employees’ actual workspace demand and track workspace pattern changes to determine needs and optimize space. Workspace optimization Increases employee productivity and happiness and reduces costs by increasing space efficiency.

What The IRA / Climate Law Can Mean For The Green Building Industry

Last week, President Biden signed the $750 Billion Inflation Reduction Act (IRA). The new law addresses inflation, climate, energy, prescription drug policy, and corporate tax changes. Roughly $370 Billion are focused on combatting climate change, including energy generation and transmission, manufacturing, transportation, agriculture, and environmental justice. 

Last week, President Biden signed the $750 Billion Inflation Reduction Act (IRA). The new law addresses inflation, climate, energy, prescription drug policy, and corporate tax changes. Roughly $370 Billion are focused on combatting climate change, including energy generation and transmission, manufacturing, transportation, agriculture, and environmental justice.

Some experts predict the nation’s electricity grid will double in capacity by 2030, largely with renewables. The IRA identified Grid-Enhancing Technologies (GETs) as an important solution for clean energy integration. The law will spur the building of new transmission and maximize the efficiency of the existing grid by implementing GETs.

The IRA reinstates and expands numerous clean energy incentives with an estimated $370 billion of new energy tax credits over the next 10 years. Microgrid development also could gain a tremendous market boost as the legislation includes up to 50 percent in investment tax credits and higher production tax credits for on-site clean power development. Some experts expect the IRA provisions to cut the cost of microgrids by 10 to 50 percent.

On the energy efficiency front, the bill offers tax credits and other incentives for improving the affordability of heat pumps and electrification in the residential and commercial building sectors. Building efficiency upgrades could accelerate lighting upgrades in existing buildings.

The IRA will affect smart building construction and operation in four main areas: energy efficiency, codes and standards, energy financing, and federal investments by the General Services Administration (GSA). The IRA provides many incentives and investments to improve and manage energy use by buildings, to which smart building technology will be key. Though many of its provisions relating to residential buildings, such as tax credits for homeowners to switch to renewable energy, the bill allocates $362 million for a commercial energy efficiency tax deduction. Many think smart building technology will be required as buildings integrate with the future smart grid, renewables, and EV charging infrastructure.

The drive to improve the building code structure began in November 2021 with the passage of the Infrastructure Investment and Jobs Act. That bipartisan law allocated $1.2 trillion for infrastructure programs and provided the DOE with $225 million over five years to fund competitive grants for “sustained cost-effective implementation of updated energy codes.” Supported by the International Code Council, the program aims to drive improvement in the implementation of energy codes, as well as water conservation and community resilience efforts. The IRA provides an additional $1 billion over 10 years for efficient building code adoption grants. Raising the bar for performance expectations will likely drive innovation and investment in more sophisticated and advanced building management and automation systems.

To distribute up to $27 billion to clean energy technologies, the IRA sets up a Greenhouse Gas Reduction Fund (GGRF). This Clean Energy and Sustainability Accelerator, or green bank, is going to deploy resources in communities that haven’t previously had enough resources deployed in them.

As established in the IRA, the GGRF will give the Environmental Protection Agency administrator authority to disburse $20 billion to eligible recipients, defined as nonprofit green banks that “provide capital, including by leveraging private capital, and other forms of financial assistance for the rapid deployment of low- and zero-emission products, technologies, and services.”

Of this $20 billion allocation, $8 billion would be dedicated to financial and technical assistance for low-income and disadvantaged communities. The provision also designates $7 billion to states, municipalities, and tribal governments to drive local investments in sustainability and efficiency—and smarten up their buildings.

Along with the incentives and funding for the private sector, the federal government plans to invest $250 million through the GSA to convert buildings owned or managed by the agency to high-performance building standards. The impact will be significant due to the sheer size of the GSA, which has an annual operating budget of $33 billion, oversees $66 billion in procurement annually, and manages approximately 8,700 owned and leased buildings. Its large footprint has enabled the GSA to become an influential leader in high-performance building and sustainable design efforts. Funding to improve the operations of GSA building stock will almost certainly involve upgrades in building management and other smart building technologies as part of the agency’s efforts to improve the operations of its significant portfolio.

The IRA helps consumers through a $9 billion home energy rebate program for buying electric home appliances and retrofits. Much of these allocations focus on low-income consumers.

The next decade could accelerate public sector assistance in rooftop solar, electric heating and cooling, and electric water heaters. Individuals who buy used electric vehicles could receive $4,000 in tax credits and $7,500 if they acquire a new EV.

Last year’s $1 trillion Bipartisan Infrastructure Law allocated $65 billion toward electric grid transmission infrastructure upgrades and construction. It also contained a $7.5 billion investment to build out a national network of EV chargers.

Two DOE Reports Characterize Current UV LEDs

The U.S. Department of Energy has released two reports which characterize the current state and viability of commercial ultraviolet (UV) LED products.

The U.S. Department of Energy has released two reports which characterize the current state and viability of commercial ultraviolet (UV) LED products. RTI International conducted these studies through a contract with KeyLogic Systems, working with the LED Systems Reliability Consortium (LSRC).

  • Initial Benchmarks of UV LEDs and Comparisons with White LEDs focuses on the construction and initial performance of commercially available UV LED components in radiometric and current-voltage tests. A test matrix containing 13 different UV LEDs was created in association with the LSRC. Testing involved at least 22 samples of each commercially available product (as of June 2021). In addition, two common, commercial white LEDs were tested to provide a benchmark against blue-pumped white LEDs. Read the report.
  • Operating Lifetime Study of UV LED Products focuses on the long-term performance and reliability of the same set of commercially available UV LEDs. Understanding the failure modes and failure rates of UV LEDs is important in understanding GUV product effectiveness over time and improving UV product reliability at the LED, lamp, and luminaire level. This information is critical to developing products with higher efficiency, lower carbon footprint, and significantly reduced environmental impact than the lighting technologies they replace. The study employed three stress tests to examine the reliability of each product. Results from stress testing, along with an extensive literature review, identified specific failure mechanisms across these UV LEDs. Read the report.

The COVID-19 pandemic put a spotlight on germicidal ultraviolet (GUV) radiation for air and surface disinfection. This technology area represents a growing opportunity to improve indoor air quality while saving energy over high-ventilation approaches. However, light-emitting diode (LED) GUV sources and fixtures available today have low efficiencies relative to visible LEDs or other UV sources (such as mercury lamps). Driven by demand for pandemic preparedness measures in buildings and good indoor air quality, many emerging GUV R&D activities target application effectiveness through increased source efficiency, improved fixture design, and enhanced reliability.

Ready Or Not, Here Comes Climate Action

Significant climate action legislation is occurring at the US Federal level, as well as in Massachusetts and Maryland.

Significant climate action legislation is occurring at the US Federal level, as well as in Massachusetts and Maryland. The US Senate and House passed the Inflation Reduction Act, with $369 Billion in climate action. President Biden just signed it into law on Tuesday, 8/16. The bill will address greenhouse gas emissions, renewable energy, electric vehicles, carbon sequestration and capture, and more.

In July, Massachusetts passed a sweeping climate bill that includes benchmarking language for buildings over 20,000-square-feet, huge energy and greenhouse gas reduction goals, and incentives for electric vehicles.

In April, Maryland enacted a mandate to end carbon emissions on a net basis economy-wide by mid-century, targeting electricity generation, building heating, and transportation. The package also incorporates environmental-justice provisions. Backers called it one of the country’s most aggressive climate change laws.

The MD Climate Solutions Now Act of 2022 contains significant provisions to decarbonize buildings and transportation. Measures to reduce building energy use could likely accelerate LED lighting retrofits.

EV incentives in the Federal, Massachusetts, and Maryland laws will all further spur the EV charger market, which a growing number of lighting manufacturers have jumped into. Last Fall’s Infrastructure Law also contained significant EV charging infrastructure incentives.

CIE Publishes CIE 250:2022 On Spectroradiometric Measurements, Measurement Uncertainties, & Instrument Calibration

The Technical Committee TC2-80 of the CIE has prepared a new technical report on the spectroradiometric measurement of optical radiation sources. The document, published as CIE 250:2022, supersedes the almost 40-year-old report CIE 063-1984.

The Technical Committee TC2-80 of the CIE has prepared a new technical report on the spectroradiometric measurement of optical radiation sources. The document, published as CIE 250:2022, supersedes the almost 40-year-old report CIE 063-1984.

It explains the basic measurement principles and provides practical instructions for the measurement of irradiance, radiation density, radiation intensity and radiant flux, including instrument calibration. In addition, the report describes in detail the physical effects relevant to spectroradiometric measurements, and in particular the estimation of measurement uncertainties. The measurement uncertainties occurring in every measurement quantitatively determine the accuracy of the calibration chain for traceable measured values.

The new technical report is for optical radiation sources in the wavelength range 200–2500 nm. The report offers a comprehensive insight into the relevant terminology and the fundamentals of calibration of spectroradiometric measuring instruments. It is a practical guide to the identification, understanding and quantification of the relevant components of measurement uncertainty and can be purchased in the CIE online shop: .

LiFi Can Now Work Around Corners And Be Securely Coded To End Devices

LEDs Magazine recently reported that engineers from Cisco are now claiming that light-based communications, known as LiFi, is gaining the capabilities to work around corners and be securely pre-coded to end devices.

LEDs Magazine recently reported that engineers from Cisco are now claiming that light-based communications, known as LiFi, is gaining the capabilities to work around corners and be securely pre-coded to end devices.

Li-Fi, or light fidelity, is a technology that uses modulated light waves from LEDs or lasers to transmit data. It is like Wi-Fi in that it provides wireless internet connections, except where Wi-Fi uses radio waves (RF), Li-Fi uses visible light or IR.

The IEEE has been working on a standard for Reconfigurable Intelligent Surfaces (RIS) as a way to intentionally redirect radio signals in complicated deployments. A research paper in March, whose authors include LiFi pioneer Dr. Harald Haas, claim that RIS-equipped Li-Fi environments ‘can lead to enhanced physical leader security’ in several different ways. For example, an RIS system can detect intruders, and then emit artificial noise in the intruder’s direction as a jamming technique. RIS elements can be pre-coded in a way that only legitimate users can decode, the authors state.

LiFi RIS can create a wireless network that only works with designated devices, allowing for an ‘intentional’ approach to network design. Radio waves don’t offer this type of precision.
