Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.
  • GULF COAST GREEN 2013 CREATE(D) HISTORY: LEARNING FROM THE PAST TO GUIDE THE FUTURE PASSIVE SUSTAINABILITY FOR EXISTING BUILDINGS SUSTAINABILITY WITH LESS “TECHNOLOGY” EXISTING BUILDINGS, DEPENDING ON AGE AND CONSTRUCTION SYSTEMS, CONTAIN MANY ASPECTS OF SUSTAINABILITY THAT MAKE THEM MORE ECONOMICALLY VIABLE THAN NEW CONSTRUCTION. COURSE SUMMARY
  • GULF COAST GREEN 2013 CREATE(D) HISTORY: LEARNING FROM THE PAST TO GUIDE THE FUTURE 1. IMPERATIVE FOR CONSERVATION OF EXISTING BUILDINGS AND EMBODIED RESOURCES. 2. INHERENT CHARACTERISTICS OF EXISTING BLDGS. 3. TAKE ADVANTAGE OF INHERENT CHARACTERISTICS FOR PASSIVE SUSTAINABILITY LEARNING OBJECTIVES
  • GULF COAST GREEN 2013 CREATE(D) HISTORY: LEARNING FROM THE PAST TO GUIDE THE FUTURE “THE GREENEST BUILDING IS … ONE THAT IS ALREADY BUILT.” CARL ELEFANTE, FAIA, QUINN/EVANS ARCHITECTS EMBODIED ENERGY AND CARBON IN EXISTING CONSTRUCTION AND MATERIALS: A 50,000 SF COMMERCIAL BUILDING IS EQUAL TO 80 BILLION BTU’S OF ENERGY, THE EQUIVALENT OF 640,000 GAL. OF GASOLINE, AT $3.75/GAL. = $2,400,000 = $48/SF IF AN EQUIVALENT NEW BUILDING COSTS $200/SF, THE EXISTING BUILDING WOULD BE 25% MORE ECONOMICAL
  • GULF COAST GREEN 2013 CREATE(D) HISTORY: LEARNING FROM THE PAST TO GUIDE THE FUTURE “THE GREENEST BUILDING IS … ONE THAT IS ALREADY BUILT.” CARL ELEFANTE, FAIA, QUINN/EVANS ARCHITECTS EXISTING BUILDINGS OUTNUMBER NEW BUILDINGS IN THE US BY 100 TO 1

  • GULF COAST GREEN 2013 CREATE(D) HISTORY: LEARNING FROM THE PAST TO GUIDE THE FUTURE WHAT IS AN EXISTING BUILDING? 1. OVER 50 YEARS OLD – “HISTORIC” 2. 50 – 30 YEARS OLD – POSSIBLY BUILT W/O AC

LESS THAN 30 YEARS OLD – PROBABLY BUILT WITH AC IN HOUSTON, 1980 IS A KEY TURNING POINT FOR OUR ENVIRONMENT: BEFORE 1980, SOME PLACES WHERE AIRCONDITIONED. AFTER 1980, EVERYPLACE WAS EXPECTED TO BE AIRCONDITIONED: BUILDINGS, HOMES, CARS
  • GULF COAST GREEN 2013 CREATE(D) HISTORY: LEARNING FROM THE PAST TO GUIDE THE FUTURE PASSIVE SUSTAINABILITY VALID FOR ALL PROJECTS, NEW AND EXISTING BUILDINGS PASSIVE APPROACHES MAY BE LESS EXPENSIVE TO BUILD PASSIVE SUSTAINABILITY TAKES ADVANTAGE OF THE CHARACTERISTICS OF AN EXISTING BUILDING, HISTORIC OR OTHERWISE, TO CREATE A HABITABLE ENVIRONMENT USING AS FEW NATURAL AND MAN-MADE RESOURCES AND ACTIVE SYSTEMS AS POSSIBLE.
