Two New Reports Link Daylighting to Worker Health and Productivity

January 21 2015

Two recently released reports summarize research linking daylighting with worker health and productivity. The first study prepared by the World Green Building Council (WBGC) aims to establish a quantifiable monetary link between energy and environmentally responsive commercial buildings and occupant wellness and productivity. The report is a meta study of hundreds of academic and industry studies covering a range of office design factors, including lighting ( daylighting and electric lighting ), thermal comfort, acoustics, interior layout and biophilia ( the connection  of people to the natural environment ). The report offers a toolkit for building owners to realize and substantiate the financial benefits of energy and environmentally responsive design strategies. The intent of the report is to help organizations integrate this type of information into financial decision-making.

The second report released by Northwestern University and the University of Illinois at Champaign-Urbana indicates that occupants of a workspace containing windows that provide daylight not only are more productive, but they also get more sleep during off hours, are more physically active, and report a higher quality of life then those who worked in spaces without daylight. Because of the dangers of sleep deprivation, as well as the productivity and health advantages of daylighting, the study’s author’s urge building owners and architects to keep window place and daylighting in their minds  when designing or redesigning office space.

LightLouver LLC Testifies at EPA Clean Power Plan Hearing

August 15 2014

Michael Holtz, FAIA, a Co-Founder and Principal at LightLouver LLC, testified at a July 30th Public Hearing at the U.S. Environmental Protection Agency  (EPA) offices in Denver regarding EPA’s proposed Clean Power Plan rule, which would reduce CO2 emissions by 30% by 2030. Michael’s testimony was in support of the rule which sets state-specific targets ( goals ) for CO2 reduction and requirements for state plans for achieving these CO2 emission reduction targets. His testimony brought attention to the role that the building sector plays in CO2 emissions, and the need for state plans to address equally supply side reduction opportunities and demand side reduction opportunities. According to the U.S. Energy Information Administration in 2013, the building sector accounts for 47.6% of total U.S. annual energy consumption, 44.6% of all U.S. CO2 emissions and 75% of all U.S. electricity consumption.

Additionally, Holtz called for more aggressive CO2 emission reduction goals implemented quicker to address the growing impacts of climate change, in large part cause by electric power plants burning coal and natural gas.

SmartMarketâ„¢ Report Identifies Barriers to Healthy Working Environments

August 14 2014

A SmartMarket Report produced by McGraw Hill Construction in collaboration with the American Institute of Architects reveals that the biggest barrier to considering the health impact of buildings is a lack of education on the connection between healthy work and living environments, and building occupants.

The report emphasizes key barriers that prevent companies from adopting design and construction strategies that take health impact into consideration. Top challenges to implementing these building practices include the large number of factors builders must consider, lack of information and data on health impact, and the lack of willingness to invest in improvements related to occupant health.

The figure above summarizes the factors influencing design and construction decisions most in 2014.

The LightLouver Daylighting System addresses a number of these factors, including energy savings, improving productivity, building impacts on health and aesthetics. In fact, the non-energy related benefits of daylighting in combination with the energy saving benefits of daylighting provide great value to the building occupants and owner.

LightLouver LLC Launches National Advertising Campaign

Beginning with the January 2014 issue of Architect, The Magazine of the American Institute of Architects published by Hanley Wood, LightLouver LLC will launch a national advertising campaign promoting deep, glare-free side-daylighting achievable with the LightLouver Daylighting System.  “Our goal is to reach more architects, and promote integrated lighting design which combines daylighting, electric lighting and lighting controls” states Michael Holtz, FAIA, Founder and Principal at LightLouver LLC. Under the theme “Daylighting Made Easy!”, each ad will focus on one of six key aspects of effective daylighting, all of which are achievable with the LightLouver Daylighting System:

  • Glare-Free Daylighting
  • Energy Saving Daylighting
  • Deep Uniform Daylighting
  • Predictable, Reliable Daylighting
  • Code / LEED Compliant
  • Economical Daylighting

“The LightLouver Daylighting System enables architects to specify a side-daylighting product that will deliver daylight deep into the space and do so in a cost-effective, glare-free manner” according to Holtz. He continues, “ LightLouver units are a non-intrusive side-daylighting solution that can provide large energy savings, compliance with stringent building and energy codes and support achievement of LEED and Green Globe sustainable design certification.”

We hope the national advertising campaign will draw the attention of the architectural community to the LightLouver Daylighting System, an economical and effective side-daylighting solution.

The first ad in Architect Magazine is shown below.
