Reducing energy use, emissions and impacts of materials

Contractors, building owners & operators, engineering and architectural firms, as well as manufacturers, are looking for green solutions. We started decades ago at CTLGroup. Green building design is an integral part of our practice.

CTLGroup's green building design construction consultants provide a comprehensive variety of engineering, consulting, research and testing services that support sustainability of the built environment:

  • Efficient use of energy, materials and resources
  • LEED compliance verification and documentation including Solar Reflectance Index testing (SRI)
  • Energy usage analysis/simulation for problem identification and resolution
  • Environmental product declaration and third party verification
  • Low carbon cementitious materials and concrete mixture design

Additional services include:

  • Energy or green audit - assess current performance and identify ways to go green
  • Building component analysis, including optimal insulation levels
  • Building envelope engineering, including insulation, thermal mass, air barriers,  vapor retarders, and moisture mitigation
  • Energy code and green building design standard compliance
  • Remaining service-life analysis, performance assessment and analysis of existing buildings and structures
  • Life-cycle inventory (LCI) or life-cycle assessment (LCA) to help assess your product, process or building; or provide data for the U.S. LCI database
  • Life cycle cost analysis (LCCA) or service-life assessment
  • Solar reflectance, SRI and thermal property testing
  • Optimal material proportioning using recycled content materials

CTLGroup has the depth of green building design experience matched by few and has been making the world a greener place-project by project-for over 30 years in several ways:

  • Determining the environmental impacts of materials through the application of life-cycle assessment (LCA) since 1993
  • Contributing to the development of ASHRAE/USGBC/IES Standard 189.1 Standard for the Design of High Performance Green Buildings (since 2006) and ASHRAE 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings (since 1990)
  • Testifying at the International Green Construction Code Hearings (IGCC) in August 2010 and the International Energy Conservation Code Hearings (IECC) since 2002
