BRICK SLIDE_001   What does sustainability have to do with genuine clay brick?  Industry commitment to a better tomorrow.  Give our future generations a healthy environment.  Brick as made for the earth from the earth.
 New Picture (1)   Clay masonry can last a lifetime, historical buildings are a testament to this.  Communities want sustainable buildings and landscapes for future generations.  “Green” design means that sustainability is a must and considers the economic and social aspect of the design in addition to the balance
 New Picture (2)   Sustainability is defined as “meeting the needs of the present without compromising the ability of future generations to meet their own needs”.
 New Picture (3)   Sustainable buildings are designed in a way that uses available resources efficiently and in a responsible manner, balancing environmental, societal and economic impacts to meet the design intents of today while considering future effects.
 New Picture (4)   Often the tendency is to focus on one aspect of sustainable design, such as energy use or environmental impacts.  This approach leaves out other equally important elements necessary for true sustainability. Truly sustainable design is best described as achieving the “triple bottom line,” that balance of environmental goals, societal goals and economic goals.
sustainable design elements slide_001   The versatility and durability of clay brick facilitate its use as part of many elements of sustainable design.
 revist brick slide_001   It’s a material you’ve long known, specified and used successfully. You know its design flexibility, durability, and low maintenance, and how its endless array of colors, shapes, textures, and sizes set the standard for beauty. The properties listed above are just a few that make brick the superb sustainable material it has been for thousands of years.
 Unsurpassed Life CycleNew Picture   Due to durability of brickwork construction, a life cycle cost analysis can often demonstrate the long-term benefits of building with brick. Brick structures/buildings have been in place for hundreds of years and they will be around for hundreds more.
 New Picture (2)   And now I must describe how the soil dug out to make the moat was used, and the method of building the wall. While the digging was going on, the earth that was shoveled out was formed into bricks, which were baked in kilns as soon as sufficient number were made; then using hot bitumen for mortar, the workmen began at revetting the brick each side of the moat, and then went on to erect the actual wall. In both cases they laid rush-mats between every thirty courses of bricks.— Herodotus, i. 179 (of Babylon)
 Exceptional Energy EfficiencyNew Picture (3)   Energy-Efficient Building Envelope. An energy-efficient building envelope is a key component in sustainable building design. Incorporation of brick masonry’s thermal mass provides numerous energy benefits, including the reduction of peak heating and cooling loads, moderation of indoor temperature swings (improved thermal comfort), and potential reduction in the size of the HVAC system. The benefits of thermal mass have been demonstrated when brick is used as a veneer, and are even more pronounced when brick masonry also is exposed on the interior of the building.
 natural ingredients_001   Brick is made primarily from clay and shale, which are abundant natural resources [Ref. 6]. Most of the clays and shale used in brick making are mined in open pits located near brick manufacturing facilities — many of which are less than a mile away. Most plants use material from the same pit extracted through multiple soil layers for a minimum of 50 years, thus minimizing their impact to the surface area.
 minimal waste_001   Building construction can generate significant amounts of waste. Because of the small, modular nature of brick, on-site construction waste can be dramatically reduced through careful design and detailing. In addition, scrap brick is easily crushed and recycled for new uses, thus avoiding the landfill. Packaging from brick is minimal and easily recycled.
 Minimal Waste ContinuedNew Picture (5)   Regional Sources. By selecting materials from regional sources, environmental impacts associated with the transport of materials can be reduced. Most brick are manufactured from materials obtained from within a few miles of the manufacturing plant. Of the 50 largest metropolitan statistical areas (MSAs) in the United States, there are more than 25 plants on average within 500 miles of each, and there are at least two brick plants within 500 miles of 49. More than 70 percent of these MSAs have at least one plant within 200 miles
 Countless Recycling OptionsNew Picture (6)   Brick can be recycled in many ways.

  • Raw brick and fired brick (grog) are recycled in the manufacturing process. Most plants require approximately 10{580b706b7a39da80a3d56953fe8b38e4696fb54136ba48cddcd6ca657ca227c8} grog to manufacture clay brick.
  • Scrap brick and brick from demolition can be crushed and recycled into new brick or used as brick chips for landscaping, baseball diamonds and tennis courts
  • Recycled brick also can be used as sub base material for pavements, on quarry roads or even as aggregate for concrete
  • Brick also can be reused (individual brick units can be salvaged and reused with proper precaution)

 

 checklist for selecting materials_001    Select materials carefully with an eye toward the future.
 building green_001   Environmental: building green reduces the impact of natural resource consumption.  Economic: improves the bottom line in terms of building operation, asset value, worker productivity, and can bring favorable zoning ordinances and tax benefits.  Health & Safety: enhances occupants’ comfort & health.  Community: minimizes the strain on local infrastructures by lessening demand for landfills, water supply, storm water management, and transportation of materials
 site planning_001   Land Use – Broad Category
Storm Water and Erosion, Site/ Habitat Disturbance, Urban Development, Brown Fields, Heat Island Effects and Utilizing Alternative Transportation.Permeable Paving.  Heat Island Effect of retaining heat around buildings due to dark colors.  Light color brick with a high Solar Reflective Index greatly reduce this effect.
 resources_001   Conservation of Material and Resources involves three distinct aspects of materials to be considered in a sustainable design.
1.  Reuse of materials and buildings along with the durability of each.
2.  Efficient use of materials (includes construction waste and
resource efficiency).
3.  Material manufacturing.
 indoor_001   Indoor Environmental Quality is critical because we spend nearly 80 percent of our time indoors.  Masonry offers superior acoustic performance offering quieter interior spaces.  Air quality is also important and masonry doesn’t contain any volatile organic compounds (VOC’s).  Mold is not able to grow on masonry keeping dangerous spores from entering the air.
 clay mining_001   This is where the life of the brick begins.  Clay is an abundant natural resource and mined from numerous locations around the world.  Very strict reclamation processes ensure that many mines will have a positive impact on the area.
 recydling materials_001   Clay and grog (recycled clay material) are crushed and screened in order to get the proper particle size for production.  Grog is a critical component to the manufacturing process and can come from numerous recycled sources.  Recycled content in clay masonry is typically above 10 percent
 process_001   The manufacturing process to make clay masonry is very efficient with almost no waste of materials.  To reduce environmental impact, 100 percent of unused clay is recycled.  Modern pollution controls have significantly reduced any production air discharges.
 finsihed_001   Sustainability is a must for all green buildings and clay masonry offers performance second to none.  Unlikely to ever need replacement, clay masonry can be utilized on buildings with a very long life expectancy.  Building in downtown Denver, Colorado.
 energy_001   Probably the best way to understand brick’s thermal mass is to think of brick as a thermal battery.
 thermail mass_001    “Thermal mass acts as a ‘thermal battery’.
 embodied energy_001   During summer it absorbs heat, keeping the house comfortable. In winter the same thermal mass can store the heat from the sun or heaters to release it at night, helping the home stay warm.”
 gasoline_001   Less to cool and heat. Buildings with exterior masonry walls, also called mass walls, utilize less energy to heat and cool than similarly insulated buildings with wood or steel frame walls.
 thermal mass_s_001   Capacity to store energy. Masonry’s thermal mass has the capacity to store warmth or cold.
 thermal mass3_001  

This results in moderate indoor temperature fluctuations, slower transfer of heat through the building envelope, and the ability of a building to store energy and shift peak energy requirements.

 ashrae_001   Energy savings due to thermal mass is dependent on climate. Mass has the greatest benefit in climates with large daily temperature fluctuations above and below the balance point of the building (55 to 65°F).
 comparison_001   Lowers peak loads. By lowering peak loads, energy dollars can be saved. For example, peak cooling loads in office buildings are often in mid-afternoon. Properly designed thermal mass can shift a portion of the load from mid-afternoon until later when the building is unoccupied or when peak load electricity costs are less.Reduces size of HVAC system. Analytical and experimental studies show that the use of materials with thermal mass in buildings reduces heating and cooling peak loads, resulting in reduced HVAC system capacity requirements. Studies show that the HVAC system in a house with mass walls can be downsized from that of a house constructed with frame walls, even when the mass walls have less insulation.
