The Art And Science Of Restoration

  1. 1. Buildings Building a sustainable future begins with restoring our past. The Art & Science of Restoration
  2. 2. Preserve Architecture is an expression of our values. Preserving architecture through building restoration is a sustainable, responsible use of resources. What is sustainable building if not preserving what we have already built? The art of craftsmanship, the science of 44,000 commercial buildings are demolished annually in the New construction is estimated to create 1.5 times more The demolition of buildings in the United States produces United States. greenhouse gas than building about 124 million tons of lasting solutions. (Environmental Building News, as cited in Architecture, April 2003) restoration. (Carnegie Melon Green Design Institute) debris every year. (Deconstruction Institute)
  3. 3. An unconventional look at building restoration Why is restoration important? Restoration is responsible and sustainable stewardship Restoration is a legacy of our resources we leave to the next generation The urgency for sustainability and preservation Architecture embodies our heritage. Our buildings of our natural resources grows daily. What can are a reflection of our values. As you tour the be more sustainable than restoring an existing great cities of the world, you can read the story building? When a building is restored we keep of these cities in their skylines... a rich story waste out of landfills and make responsible use worth preserving. Through restoration, we of existing resources. By restoring rather than preserve our link to the past. demolishing, we leave the built environment better than we found it, using our resources Restoration is about vitality wisely for today’s needs while being mindful of and renewal Restoration: the needs of future generations. Restoration preserves our history, our culture and What does it really mean? our progress. If we allow our buildings to fall to Restoration utilizes existing infrastructure. It Building restoration can be defined as preserves the equity invested in buildings such corrosion, deterioration and disrepair, we erode the act of preserving assets, returning as embodied energy, labor, money and emotion. the fabric of our neighborhoods and communities. them to their former position or an It presents us with the opportunity to make an Building restoration has the power to transform. important and significant impact on the built improved condition. It can heal and revive, strengthening the social world that enhances the quality of life. Restoration is structure of our communities. about craftsmanship It requires thoughtful planning, skill, knowledge and ability. But it also takes passion and appreciation for the legacy we leave for the future; a perspective that includes the important relationship between buildings, their inhabitants and the environment.
  4. 4. Search It’s time to find a better way... one that avoids demolishing repairable structures, filling landfills with construction debris, and destroying the character of our cities. Sustainability begins with The EPA has noted that building restoring our own construction debris constitutes around a third of all waste generated in the U.S., and has communities. projected that more than 27% of existing buildings will be replaced between 2000 and 2030. (“Historic and Green”, Traditional Building, Donovan Rypkema)
  5. 5. The search for better solutions begins with asking the right The challenges of restoration Knowledge is the key to long term solutions questions. Restoration is vital to the future of our cities, but the industry faces many challenges. Restoration Material science is rapidly evolving, with constant efforts are often “too little too late.” Problems are technological advancements as well as changes ignored or repairs are minimal – treating the to meet new regulations and performance symptoms rather than the cause. Job site requirements. Knowledge is essential in order to variations, non-standard design and fast track make informed decisions and formulate the most construction schedules can compromise long effective restoration strategies. To be successful, lasting repairs. you need a knowledgeable team. Many repairs do not last because of lack of BASF restoration specialists join with design knowledge about the root causes of the problems, professionals and contractors to solve problems by material chemistry and interaction, misdiagnosis or bringing knowledge, experience and insight to the inexperience. The complexity and volume of task. They are able to understand the relationship information can be daunting – design professionals between various chemistries, how they relate to and contractors cannot know it all. one another and how they function together in the building envelope. A partnership of knowledge The better solution: A holistic approach can be a powerfully effective tool. and a comprehensive strategy It’s a simple premise: look at the entire picture, past, present and future. For the building envelope to function properly and be sustainable, it is critical that all conditions are examined and all questions answered. Every project requires a unique set of solutions. Successful repair combines knowledge and experience with a comprehensive strategy that dovetails with the right compatible products and the most effective methods. From 1957 to 1962, two hundred buildings over 17 square blocks in Minneapolis’ Gateway district were demolished. This amounted to 40% of the city’s historic central business district. (Lost Twin Cities, Larry Millet)

Towers Condominium Venice, Florida PROBLEM Built in 1968, the seven story structure suffered from a long list of maladies, from waterproofing problems to structural deficiencies. SOLUTION BASF’s range of repair solutions allowed the contractor flexibility in approaching the building’s unique repair challenges. Repair mortars, sealants, adhesives, corrosion inhibitors and waterproofing systems were used to create the necessary structural repairs while improving appearance and providing long term protection.
