Eighteen building, 408 unit Condominium Complex

Forensic engineering, field investigation, photo-documentation of existing conditions and code compliance issues of HVAC and plumbing systems, and fire protection sprinkler freeze-burst issues.

Forty building Townhouse Complex

Forensic engineering, field investigation, building envelope thermography, photo-documentation of existing conditions and code compliance issues of HVAC and plumbing systems.

Twenty-seven Building Townhouse Complex

Forensic engineering, field investigation, photo-documentation of existing conditions and code compliance issues of HVAC and plumbing systems, report of findings.  Flue draft and combustion testing of water heaters and furnaces.

136,000 square foot Mixed-Use Commercial and Residential Complex

Forensic engineering, field investigation, photo-documentation of existing conditions and code compliance issues of HVAC, fire protection, and plumbing systems, including acoustic issues involving sound transmission and hydronic turbulence-generated sound, balcony drain leaks, snowmelt leaks, and report of findings.

Palmer Ridge High School

Peer review for new high school.  Systems include ground-coupled heat pumps, energy recovery ventilation, and a variety of measures intended to make this school one of the lowest energy use high schools in the State.

GSA: Araj U.S. Courthouse, Denver, Colorado.

Peer review and commissioning support for new US GSA courthouse facility in Denver, Colorado. Systems included displacement ventilation, high-efficiency lighting/controls, photovoltaics, and district heating and cooling.

Confidential Client, Denver, Colorado

Investigation and troubleshooting was performed for a confidential client in the City of Denver.  Existing heating systems were experiencing equipment shut-down problems in multiple buildings with similar systems.  The cause was found to be improper venting, damaged attic vents, and control problems related to tempering valve selection.

Confidential Client, Denver, Colorado

Investigation project for a confidential client looked into uneven heating and cooling.  The cause was found to be related to building pressurization problems and inadequate return air paths.

Great West Life; Tower II Balancing Consultation; Englewood, Colorado

Project Manager and Project HVAC Engineer for system troubleshooting consultation. Evaluation of apparent stack effect problems and HVAC system imbalances. During the project, discovered numerous contributing problems including substantial ductwork and plenum leakage and damper control problems.

Lincoln Center; Stack Effect Study; Denver, Colorado

Project Manager and Project Engineer for HVAC system evaluation. During the evaluation, discovered numerous related problems including fan tracking control problems and apparent stack effect problems due to modifications made to counteract freeze-up problems.
