I <br />ATTORNEY COLLINS EXPLAINED TO THOSE PRESENT THAT THE STATE <br />HAS MANDATED THAT THE COUNTIES PASS AN ENERGY EFFICIENCY TYPE CODE <br />THE CITY OF VERO BEACH HAS BEEN MANDATED THE SAME. HE CONTINUED THAT <br />THE COUNTY THROUGH ITS BUILDING BOARD OF ADJUSTMENT HAS REVIEWED THE <br />PROPOSED CODE; THE BUILDING DEPARTMENT HAS MADE RECOMMENDATIONS; AND <br />THE PROPOSED ORDINANCE IS ENTIRELY CONSISTENT WITH THAT OF THE CITY OF <br />VERO BEACH. ATTORNEY COLLINS FELT SINCE WE HAVE A JOINT BUILDING DEPART- • <br />MENT WITH THE CITY, IT WOULD BE IMPOSSIBLE TO WORK WITH DIFFERING <br />ORDINANCES. HE THEN INTRODUCED JOHN CALMES, REGISTERED ARCHITECT AND <br />CHAIRMAN OF THE BUILDING BOARD OF ADJUSTMENT. <br />MR. CALMES STATED THAT THE CODE APPROACHES SOME OF OUR COUNTRY'S <br />ENERGY PROBLEM. HE DISCUSSED TABLES SHOWING THE ENERGY USED IN THE <br />UNITED STATES, AND NOTED THAT BUILDINGS USE ABOUT 43%. OF THAT, THE <br />GREATEST AMOUNT OF ENERGY IS USED IN SINGLE FAMILY HOMES, WITH MULTI- <br />FAMILY SECOND, AND COMMERCIAL BUILDINGS THIRD. MR. CALMES THEN DISCUSSED <br />"U -VALUES," AND EXPLAINED THAT THESE RELATE TO THE DEGREE OF THERMAL <br />RESISTANCE OF BUILDING COMPONENTS. HE..NOTED THAT THE CODE ADOPTED BY <br />THE CITY OF VERO BEACH LAST NIGHT PRIMARILY EXEMPTS BUILDINGS THAT ARE <br />NOT TO BE HEATED OR COOLED, SUCH AS WAREHOUSES, BODY SHOPS, ETC., AND <br />IT ALSO EXEMPTS SINGLE FAMILY RESIDENCES OF LESS THAN 1,500 SQ. FT. HE <br />STATED THAT ITS GREATEST AFFECT ON OUR RESIDENTIAL CONSTRUCTION WILL BE <br />IN TERMS OF CONCRETE BLOCK CONSTRUCTION. MR. CALMES EXPLAINED THAT THE <br />t U -VALUE OF A CONCRETE BLOCK WALL IS APPROXIMATELY .29, AND THE MAXIMUM <br />IS TO BE .30 SO THAT ALLOWS FOR NO GLASS IN THE WALL WITHOUT ADDING <br />INSULATION. HE CONTINUED THAT IF INSULATION IS ADDED TO THE WALL, YOUR <br />PERCENTAGE OF GLASS TO THE OVERALL PERCENTAGE OF GROSS WALLS CAN INCREASE <br />UP TO ABOUT 20% OF GLASS AREA,AND YOU CAN APPROACH A PERCENTAGE OF CLOSE <br />TO 35% GLASS BY USING INSULATED GLASS AND INSULATING THE BLOCK WALL TO <br />ITS MAXIMUM. MR. CALMES FELT THERE HAS BEEN A GOOD DEAL OF MISUNDER- <br />STANDING ABOUT THIS CODE, AND THAT THERE IS A GOOD DEAL OF FLEXIBILITY. <br />MR. CALMES INFORMED THE BOARD.THAT SECTION 5 OF THE ORDINANCE IS WHAT <br />OUR BUILDING DEPARTMENT WILL BE DEALING WITH, AND THERE ARE DIFFERENT <br />WAYS OF DEALING WITH THIS. <br />19 <br />39 PAcE41 <br />MAR 2 1* 1979 <br />
