1. SUNTERRAENERGYBLOCKThe Smart Way to Build

2. New Building MethodThe construction industry is changing and future homeownersare looking for the most cost effective and energy efficientways to build new homes. While builders are trying to insulatethe home envelope better, using windows that dont lose heatand creating barriers to heating/cooling loss, there has beenno breakthrough in the capacity to store heat within thebuilding itself until now. 3. T her mal MassThermal mass is a term used to describe the ability of buildingmaterials to store heat, or thermal storage capacity. The basiccharacteristic of materials with thermal mass is their ability toabsorb heat, store it, and at a later time, release it.WinterIn winter, thermal mass can store the heat from the sun or aheating source to release it at night, helping the home staywarm. 4. T her mal MassAppropriate use of thermal mass throughout your home can makea big difference in comfort and to heating and cooling bills.SummerThermal mass acts as a storage unit, absorbing hot air in thesummer to keep the house cooler and more comfortable. 5. High T her mal MassBuilding materials that are heavyweight store a lot of heat soare said to have high thermal mass. Materials that arelightweight do not store much heat and have low thermalmass. Most residential construction today is built using light-weight materials.Light ConstructionHeavy Construction2 x 6 Wood Wall 5 lbs8 Block Wall 80 lbs2 x 10 Wood Floor 7 lbs6 Concrete Slab 50 lbs12 lbs/sf 130 lbs/sf 6. Ener g y RequirementsThe use of heavyweight construction materials with highthermal mass, i.e., concrete slab floors and EnergyBlockwalls, can reduce total heating and cooling energyrequirements by up to 35% compared to a home built oflightweight construction materials with a low thermal mass. 7. Exter nal InsulationFor maximum effectiveness, thermal mass should be leftexposed internally allowing it to interact with the buildingsinterior. For this reason, Insulating Concrete Forms (ICF)offer little thermal mass benefit.Insulation must be on the exterior surface only. 8. Ener g yBlockSunTerra EnergyBlock is apatented new system poised totake advantage of high thermalmass with exterior insulation.This new system is made up of aspecially designedconcreteblock with dovetail grooves and amasonry-insulationconnectorstrip to retain rigid foaminsulation, making it ready toattach your choice of siding. 9. Higher Standar dsSunTerra EnergyBlock exceeds the International EnergyConservation Code (IECC) insulation requirements for woodand ICF walls with comparable insulation Rvalue in allclimate zones.Zone 5 ExampleZone 4 Example 35% better than wood walls62% better than wood walls 24% better than ICF walls 50% better than ICF walls 10. DesignSunTerra EnergyBlock allows architects, builders andhomeowners to design and construct a home with a versatilelook that can either feature the aesthetic masonry interiorsurfaces or conceal them for a traditional plaster wallappearance. EnergyBlock comes in multiple colors andfinishes. 11. InteriorSunTerra EnergyBlockprovides masonry value,strength, and beauty. 12. Comparison of ICF vs .
