EMF in Schools – Collaboration for High Performance Schools For many years CHPS has been a leader in identifying sustainable and healthy building trends for school buildings. Long before LEED for Schools, there was the Collaboration for High Performance Schools Criterion and scorecard. This rating system has been tested and proven effective, and recently has

EMF Electric Fields EMF design consulting for human-generated electrosmog should involve Radio Frequency (RF) radiation, dirty electricity (high-voltage transients), low-frequency magnetic fields, and low-frequency electric fields. These four elements can be wrapped under the umbrella term, “electromagnetic radiation,” or “EMR.” This blog focuses on basic practices to minimize low-frequency EMF electric fields during design and construction. This

Eichler Remodel – Healthy & Efficient Home Why write about an Eichler remodel? Because my family is lucky enough to call this our first home, and remodeling has almost completely absorbed me for the past 3 months! This isn’t just a remodel, it’s a green Eichler remodel. What is an Eichler? Joseph Eichler was a

An Insider’s Point of View Being an architect myself and having worked as an architectural project manager until 2012, I have an insider’s view into the profession.

Last year, I petitioned the USGBC Technical Committee on Homes and received the green signal to pursue LEED certification for a 32 story apartment tower in San Francisco’s Transbay neighborhood. Midrise V 2010 allows certification for residential buildings of 4 to 12+ stories with exceptions made for taller buildings on a case-by-case basis. Residential projects

Understanding LEED IAQ Testing Requirements LEED 2009 and LEEDv4 both have credits that require building flush-outs or building air quality testing prior to occupancy. The credit requires that after construction ends, the GC must install new filtration media and flush-out the building by supplying a total air volume of 14,000 cubic feet of outdoor air per square

For folks building a new home, the job of selecting the Energy Efficient windows can be daunting. Based on the nature of the contract, the architect may or may not be involved in the window selection. Their contract may end with assisting the home owner with obtaining the permit. In such cases the homeowners may rely

We are excited to announce that we are new members of the U.S. Green Building Council – Northern California Chapter’s Building Health Initiative! The Building Health Initiative is a two-year program in which Northern California industry leaders from multiple sectors have pledged to promote health and wellness. Members have made commitments to take simple but

We decided to lighten the mood at Healthy Building Science by creating a funny building science video about what we do. What started off as a standard informational video soon turned into something very different. We hope you enjoy the results of this building science video. In October 2013, we assembled a team consisting of

You may have heard about the problem with flame retardants in polyurethane furniture foams. If you haven’t, and you want a safer sofa, I highly recommend reading the Chicago Tribune’s exposé on the flame retardant industry: Playing With Fire. The California flammability standard, known as TB117, in effect required manufacturers to use toxic flame retardant chemicals
