Jeff May has spent his career helping people identify what's causing their chronic health problems. In My House Is Killing Me! (one of the four books he has written or cowritten) he draws on the dramatic personal stories of his clients' suffering and relief to help readers understand the links between environmental factors and problems like allergies and asthma. Explaining how air conditioning, finished basements, and other home features affect air quality, he offers a step-by-step approach to identifying, controlling, and often eliminating the sources of indoor pollutants and allergens. If we could see this contamination, Jeff observes, the air would look as murky as stagnant water, and we would know not to breathe it. Jeff is a Certified Indoor Air Quality Professional, a Council-Certified Microbial Consultant, licensed as a mold assessor/inspector in the states of FL and NH, and holds a Certificate in Food Science Technology, MIT.
Reading, My House Is Killing Me! allows you to see your house the way an expert would. Just as he looks at spaces and systems during an indoor air quality investigation, May focuses first on the areas of daily life (bedrooms, bathrooms, kitchen), then looks into attics and basements (including heating and air conditioning), and finally moves outside to the garage and the exterior of a home. Along with offering a wealth of practical advice and proven solutions for various problems, he includes a glossary of terms and a list of valuable resources.

In 2009, Corbett Lunsford started teaching pros through his Building Performance Workshop. (He’s hosted over 100 YouTube videos and 60 interviews for the Building Performance Podcast.) Along with his wife, Grace, he then created the first-ever TV series on measured home performance and building science, which airs on public television stations nationwide. Corbett’s goal is “to package building performance so it can easily be understood and used by professionals and consumers alike, for better buildings worldwide. We need to quit kidding ourselves that homeowners are aiming for efficiency or sustainability and start aiming at what all homeowners aim for: living in a better home and getting a better life.” He has performed comprehensive home performance analyses and building investigations, and presented courses in partnership with National Healthy Homes, Air Conditioning Contractors of America, and the RESNET and Affordable Comfort (ACI) Conferences. He also wrote the book, Home Performance Diagnostics: the Guide to Advanced Testing and developed the APT Reports software tool.

Carl Grimes is nationally recognized as a professionally accredited Healthy Home Specialist (HHS) and a Certified Indoor Environmental Consultant (CIEC). Equally important, he personally experienced a series of unhealthy homes. He is all too familiar with the uncertainty, exhaustion, and skepticism inherent with the struggle to finally recognize and accept that his home was perhaps not his safe and secure “castle,” but was instead contributing to his puzzling declining health and sense of well‐being. 

Since 1987, Carl has worked nationally as a private consultant guiding people who suffer from unhealthy houses. He has developed action plans and verification methods designed to eliminate health issues in homes. His clients include mothers, children, property managers, attorneys, health care providers, insurance adjustors, teachers, parents, architects, builders, and remediation contractors. In 1999, he authored the book, Starting Points for a Healthy Habitat, based on his personal experience, as well as the experiences of his clients, living in unhealthy environments. This brought him to the attention of the national Indoor Air Quality Association.  He was elected to their Board of Directors in 2002, and recently served as their President.

Carl is now the Vice President of Practice for the International Society of Indoor Air Quality and Climate. Carl has served on, created, and chaired a variety of committees writing industry consensus standards.

David Johnston, founder and President of What’s Working, Inc., is one of the pioneers of the sustainability movement in the US. For the last 30 years he has been working to transform the building industry to become greener and more sustainable. David worked as a consultant to the USDOE solar program from 1978-81. During that time, he was involved with the early work at the Solar Energy Research Institute and the Regional Solar Energy Centers. He was responsible for the commercialization of passive solar technology and the integration into the residential building industry and the introduction of the technology to many building industry trade associations.

David continued with his passive solar career by founding the award-winning company, Lightworks Construction, Inc. For ten years, Lightworks built passive solar homes and offices across the DC, Virginia and Maryland market. He was named builder of the year by the DC chapter of the National Association of the Remodeling Industry and inducted into the Remodeling Hall of Fame for his innovative work.

In 1992, he sold Lightworks and moved to Boulder, Colorado to apply his experience in passive solar program development to green building. In 1995, his new company, What’s Working, developed the first green building code in the US for the City of Boulder. He was inspired in 1992 after the first green building program in the US in Austin, TX and was given a Sustainable Development award at the Earth Summit in Rio de Janeiro to do the same thing in Boulder.

David established the first private sector green building program in Denver, CO through the local Home Builder’s association. It is now the largest program in the private sector and was the catalyst for the National Association of Home Builders to develop national green building guidelines.

David was part of the development team for the Leadership in Energy and Environmental Design (LEED) that has transformed the market for green commercial buildings in the US. He was also a co-director of the original LEED for homes development process in 2000, another national market transformation program.

Over the last 8 years he has developed green building programs throughout Colorado, for the City of Los Angeles, the San Francisco Bay Area (now statewide), Minneapolis, Boston, Phoenix, Seattle, and Boulder and has consulted with other cities across the country and Canada to create market-based building programs.

Altogether, he has influenced the construction of tens of thousands of green homes built from coast to coast. The unique quality of his work is to use a whole-system approach that brings together all the relevant stakeholders who deliver a home to the consumer. This approach has focused on the human side of sustainability to create market demand for innovative solutions for affordable, environmentally friendly housing across the country.
