Test House Studies Confirm that LoE2 Glass Reduces Energy Usage by 20%. To obtain this proof, Cardinal Authorized three long-term studies in locations across the country - California, Texas and Indiana. Identical new houses were purchased in each location, and the effects of different glazings on energy usage were scientifically measured and monitored by outside experts

Energy Savings Calculator

In every case, the test projects can reduce energy consumption, saving home-owners on heating and cooling bills while making homes more comfortable year around. Builders can save on the cost of heating and cooling equipment. Projections from these results show that LowR-366 will expand on these savings.

Energy Savings up to 20%. When compared with various glass types - such as high solar gain low-e [HSLE], tinted and clear glass -LoE2 saved energy on combined heating and cooling in every test site. Total annual savings ranged from 15-20%

Significant HVAC savings. Clear or tinted glass created 50-60% of the cooling load. But because LoE2 glass cuts solar heat gain in half, project houses were able to utilize smaller air conditioning units and maintain proper temperatures. All tests validated the A/C sizing calculations. The equipment savings realized - typically one ton or up to $1,000 per house would normally
be enough to more than offset the increased cost of LoE2 glass.

With air conditioner now properly sized, better dehumidification was also achieved through the cooling season. And a smaller A/C unit running full time is more efficient - it uses less energy and improves comfort.

Improved comfort year around. The Energy Savings aspect of LoE2 glass is only part of the story. Comfort year-round. This can provide warmer glass in winter, cooler rooms during the “swing” season, and more comfortable rooms in direct sun.
