Sustainability & Historic Buildings & Cool n Photocatalytic Materials

Historic buildings were traditionally designed with many sustainable features that responded to climate and site.

Rehabilitating historic properties can also be a critical part of promoting energy efficiency by preserving the energy already represented by existing buildings rather than expending additional energy for new construction.

Current codes and many green building standards, however, do not always provide a clear path forward on how best to redevelop and revitalize historic and other existing buildings to achieve sustainable outcomes.

Communities that seek to both increase their sustainable investments and protect their historic assets must resolve standards and policies that can at times conflict, and which may render some projects financially infeasible.

How novel technologies such as the "Cool" and "Photocatalytic" materials technology could probably help?

  1. 1. Cool and Photocatalytic Materials Perdikis Prokopis Αbolin Co HISTORIC BUILDINGS SUSTAINABLE CONSTRUCTION – INTELLIGENT MATERIALS COST 540, Application of photocatalytic technologies for cultural heritages protection, NCSR Abolin Co Greece Demokritos, Athens, Greece, Mr Prokopis Perdikis 29- 30 October 2009. www.abolinco.com
  2. 2. Historical Buildings and Cultural Heritage Monuments: Background Identification Sustainability Trends and Approaches Related Problems ( Urban Heat Island, Air Quality, Energy Use) Why and Where Cool and Photocatalytic Materials COST 540, Application of photoca talytic technologies for cultural heritages protection, NCSR Abolin Co Greece Demokritos, Athens, Greece, Mr Prokopis Perdikis 29- 30 October 2009. www.abolinco.com

  4. 4. The Biggest Problem? Urban buildings use more energy, water and materials than any other consumer They also produce more waste than any other source - The world needs a new vision of urban building and a new architecture of sustainable COST 540, Application of photoca talytic technologies for cultural heritages protection, NCSR Abolin Co Greece Demokritos, Athens, Greece, Mr Prokopis Perdikis 29- 30 October 2009. www.abolinco.com
  5. 5. Historic buildings are inherently sustainable: Historic buildings were traditionally designed with many sustainable features that responded to climate and site. ANCIENT THEATRE IN EPIDAUROS COST 540, Application of photoca talytic technologies for cultural heritages protection, NCSR Abolin Co Greece Demokritos, Athens, Greece, Mr Prokopis Perdikis 29- 30 October 2009. www.abolinco.com
  6. 6. When effectively restored and reused, these features can bring about substantial energy savings. Taking into account historic buildings' original climatic adaptations, today's sustainable technology can supplement inherent sustainable features without compromising unique historic character.

  7. 7. There are Standards for four distinct, but interrelated, approaches to the treatment of historic properties--preservation, rehabilitation, restoration, and reconstruction: • preservation, • rehabilitation, • restoration and • reconstruction. LEED-EB® SYSTEM www.usgbc.org 36 CFR Part 67 US Std. COST 540, Application of photoca talytic technologies for cultural heritages protection, NCSR Abolin Co Greece Demokritos, Athens, Greece, Mr Prokopis Perdikis 29- 30 October 2009. www.abolinco.com Modern Approaches?
  8. 8. Preservation focuses on the maintenance and repair of existing historic materials and retention of a property's form as it has evolved over time. (Protection and Stabilization have now been consolidated under this treatment). Rehabilitation acknowledges the need to alter or add to a historic property to meet continuing or changing uses while retaining the property's historic character. Restoration depicts a property at a particular period of time in its history, while removing evidence of other periods. Reconstruction re-creates vanished or non-surviving portions of a property for interpretive purposes.

  9. 9. The following issues require special attention: 1) Sustainable Sites - Heat Island Reduction 2) Water Efficiency - Water Use Reduction 3) Energy and Atmosphere – Energy Use Reduction 4) Materials and Resources - Use of natural materials from the near site, use of existed damaged materials from the building, - Environmental and Sustainable criteria for new materials 5) Indoor Environmental Quality - Ventilation, Outdoor Air Quality, Sick Building Syndrome - Lighting and Daylighting COST 540, Application of photoca talytic technologies for cultural heritages protection, NCSR Abolin Co Greece Demokritos, Athens, Greece, Mr Prokopis Perdikis 29- 30 October 2009. www.abolinco.com

  19. 19. Photo-Catalysis is defined as "acceleration by the presence of as catalyst ( i.e. TiO2)". A catalyst does not change in itself or being consumed in the chemical reaction. This definition includes photosensitization, a process by which a photochemical alteration occurs in one molecular entity as a result of initial absorption of radiation by another molecular entity called the photosensitized.

The use of Cool and Photocatalytic materials even on a microclimatic scale ( surrounding urban area and buildings if any) can positively contribute to the Improvement of the microclimate conditions and therefore to eliminates harsh environmental factors and phenomena:  Urban Heat Island consequences reduction ( less heat stress in microclimate, Energy Savings, Smog mitigation)  Harmful Pollutants Decomposition ( Nox, Ozon, SO2, Bacteria)
