                   Energy 
                    use and our environment are inexorably coupled. The International 
                    Panel on Climate Change, a prestigious group of 2,500 scientists 
                    from around the world, stated in their 1995 report that "...human 
                    activities are having a discernible impact on global climate." 
                  It has 
                    also been estimated that more than 85% of our influence on 
                    climate is a direct result of energy use and that, in the United 
                    States, about 35% of our primary energy consumption stems 
                    from energy use in buildings. Our best scientific estimates 
                    indicate that energy use in buildings can be cost effectively 
                    reduced by 30-50%. If this were accomplished in only some 
                    20-25% of new construction over the next decade it would be 
                    the equivalent of taking 20% of the cars off our roads. It 
                    would also save those building owners more than $40 billion 
                    in energy costs and achieve 10% of the greenhouse gas emission 
                    reductions needed to comply with the Kyoto protocol. 
    
              For an exemplary 
                    illustration of what can be technically accomplished in this 
                    arena, consider the monitored air conditioning data in the 
                    figure below, which comes from a pair of side-by-side homes 
                    of the same floor plan and orientation but with different 
                    energy efficiency features. 
                   
                      
                  These 
                    data show that the efficient home (labeled PVRES) uses 83% 
                    less energy for air conditioning than the standard home (labeled 
                    Control), which complies with Florida's minimum standards 
                    for building energy efficiency in new homes. For detailed 
                    information on the field tests represented by these monitoring 
                    data, visit the research report introduction 
                    on the FSEC web site.
