"A key strategy in creating environmentally friendly, energy-efficient education spaces is capturing abundant daylight and reducing the reliance on artificial light. Efforts to maximize daylighting in school facilities have taken many forms as techniques have grown more sophisticated.... For architects and administrators who have reaped the benefits of many of these strategies and are seeking even more daylighting dividends, one characteristic to consider that some may be overlooking is the reflectivity of the flooring material selected for a space."

"The complexity of lighting design has made commissioning of lighting controls an essential part of projects. Commissioning for the most part is voluntary; however, if an owner is contemplating U.S. Green Building Council LEED certification or if ASHRAE 90.1-2010 compliance is required, commissioning is mandatory."

Why Incorporate a Shading System?

Environmental Design + Construction, Nov. 2014, by William Maiman.
http://www.edcmag.com/articles/95974-why-incorporate-a-shading-system

"The challenge for architects, building owners and engineers is to provide as much daylight on the interior floors for the longest period of the day so that electrical lighting can be turned off and reduce energy costs/lower greenhouse gas emissions at power generating facilities. For the occupant, solar radiation can be more than an annoyance. Interior heat gain aside, most people are very sensitive to a slight variation of temperature."

and_Healt_27101.aspx


"Usually HVAC systems and lighting are the first places most people think to start when it comes to improving energy efficiency in hospitals and health care facilities. These are, indeed, critical elements of the journey; however, one might argue that the first place one should actually start is with the building envelope, because it’s where energy savings opportunities really begin and then carry through its affiliated processes."
