D&H Building Science™

D&H Building Science is the analytical method we use to determine the best balance of these elements for your specific project.
A structure’s energy efficiency depends on four elements:

  • Insulation
  • Moisture control
  • Air sealing
  • Indoor air quality


  • Significantly reduced utility costs
  • Improved indoor air quality for more dust-free, draft-free living
  • Safeguards against mold (now excluded by many homeowners insurance policies)
  • Reduced outside noise
  • A more comfortable, healthier structure environment
  • Possible tax credits for qualifying structures
