The latest Omni Block HERS evaluation was recently completed in Alvarado, Texas. The 2512 sq. ft. single-story house, owned by Mr. and Mrs. Pete Muzika, scored a 58. This basically means that the house should perform 42% better than the prevailing energy code. The certificate can be seen below. The HERS evaluation includes a blower door test and a duct blaster test as well as the make and model of all appliances. The third-party testing company, TexEnergy Solutions, used an R-19.6 for the Omni Block walls. When questioned about why they used this lower R-Value the lead project coordinator responded that 19.6 was the highest R-Value that this region can input. Any higher R-Value inputed would not change the overall result.
Notice that TexEnergy projected the energy consumption to completely run this house at $2,602 annually or approximately $214 a month on average. The owners have now lived in the home for over 5 months, keeping their thermostat set at 73°, and the actual average energy cost has been $110 (and that usage includes a large water pump to irrigate their pasture, which was not included in the TexEnergy projection).
Statement of fact: This house, built with Omni Block is beating the utility projection by 50%.
