Natural Gas Demand Response

Our fully automated thermal window shades work with over 90% of windows. The patented design dramatically improves the thermal performance of buildings. In cold climates the technology normally achieves paybacks in four to five years.

Using Advanced Shade Technology to Reduce Natural Gas Consumption



Existing Windows | Millions of Opportunities for Dramatic, Cost Effective Energy Savings

  • Across the US, DOE estimates that 33% of windows are single pane
  • —44% of the windows in New York City are estimated to be single pane
  • —This percentage is noted to be even higher in many European and Asian cities
  • —With single pane windows Uficient Shades triple efficiency
  • For double pane, with no thermal break (the majority of commercial double pane windows) energy savings double


More Glass | Window to Wall Ratio is Growing

  • —In 1940 22% of the average building exterior was windows. Today this number often exceeds 70%
  • Although the performance of glass has improved, the use of glass has expanded significantly
  • Larger, more efficient windows are still responsible for 18 to 38% of average building energy use


Economics | Window Replacement is not Cost Effective

  • —In union labor markets (most northern, cold weather cities) RS Means costing data projects 33 to 46 year payback for commercial window replacements
  • Uficient thermal shades achieve payback from energy savings in 4 to 5 years
