Ghost Ranch is a northern New Mexico site at Abiquiu that appears in this archive as the founding ground of the state’s organized passive-solar movement: the New Mexico Solar Energy Association was co-founded there in 1972, the first Life Technic conference (1972) was hosted there the same year, and NMSEA’s inaugural Sun-dwellings project built its passive-solar test dwellings there from 1976. Peter Van Dresser is buried at Ghost Ranch beside his wife Florence.
NMSEA founding and the first Life Technic conference (1972)
NMSEA’s own history states it “was founded in 1972 in Ghost Ranch, New Mexico by Peter van Dresser, Steve Baer, and Keith Haggard.” The ASES regional history (Bruce D. Hunn, 2022) calls Keith Haggard “the principal founder” and places the site at Abiquiu; the Corrales Comment obituary for Steve Baer likewise records the 1972 co-founding at Ghost Ranch. (Haggard is a distinct person from Ken Haggard of Cal Poly, with whom earlier passes of this wiki conflated him.)
The three founders hosted the first “Life Technic” conference at Ghost Ranch that same year, with over 50 other members sharing information about solar energy; the conference proceedings became NMSEA’s first official publication. Van Dresser served as NMSEA’s first president and Keith Haggard as executive director.
The Sun-dwellings project
Ghost Ranch was the site of NMSEA’s first project, the Sun-dwellings. Van Dresser headed the design team — with William Lumpkins, David Wright, Francis Wessling, Benjamin “Buck” Rogers, Mark Chalom, Aubrey Owen, Keith Haggard, and Baer — which began meeting in Santa Fe in 1973 and designed four two-bedroom dormitory units for Ghost Ranch. NMSEA’s history pages describe the four 20’ x 40’ test structures as demonstrating a lean-to greenhouse, a Trombe wall, direct gain, and a control building.
Construction began in the summer of 1976 under Quentin Wilson and Mark Chalom, using local trainees. Per the ASES history, the best-performing building achieved 78% of its needed heat, against 18% for the control building.
Funding accounts differ slightly across NMSEA’s own pages: one credits a $34,000 grant from the Four Corners Regional Commission (echoed in the Van Dresser biography sources, which add that the grant was partial funding); the other puts total federal grants at about $102,000.
A Ghost Ranch Sun Dwelling also appears in Baer’s own retrospective canon: his 2009 AIA passive solar slideshow lists “Sun Dwelling / Ghost Ranch — Peter Van Dresser, Abiquiu, NM (Direct Gain and Trombe Wall)” among the New Mexico projects surveyed.
Van Dresser’s burial
Peter Van Dresser (died June 20, 1983, in Santa Fe) was buried at Ghost Ranch beside his wife Florence. NMSEA’s history marks his death as the start of the organization’s post-1983 decline.
