She was designing a remodel, which included the kitchen, and the designer had
LEED EMF ID Credit Application The USGBC/LEED recently denied an Innovation in Design (ID) credit application for Magnetic Field (EMF) Reduction. This post includes the official LEED EMF ID Credit Application. The following text is in the traditional formal of an ID credit application and request for a Credit Interpretation Ruling (CIR). Unfortunately the USGBC
EMF LEED Credit Citing the need for more research on human health effects, and questioning long-established Building Biology approaches to minimizing electromagnetic fields (EMF), the USGBC and denied a recent application for a EMF LEED Credit. Healthy Building Science was the LEED for Homes (LEED-H) consultant for two residential properties (CA and NH) that intended
Mold Testing Air Quality Lab Interpretation People with asthma and mold allergies are the first to ask about mold testing.

People like the idea of collecting samples and getting actual data back from a microbiological lab, but mold testing results are highly variable and easily misinterpreted. For there to be statistical significance in the results there must be many samples collected, and most project
