ANALOGIA (OVVIA) CON LA MEMBRANA CELLULARE
Più o meno parliamo della stessa cosa, più o meno le regole sono quelle

1. The looming requirement for facade retrofit should be regarded as a fundamental infrastructure
problem; energy efficiency and carbon reduction goals cannot be achieved without addressing this
problem.
2. Meeting the demand will be costly and complex, with a high potential for the process being
wasteful.
3. There is urgent need for defining appropriate retrofit strategies, evaluation criteria for their
application, and the definition of means and methods for the implementation of the various
strategies, possibly taking the form of best-practice guidelines for the various stakeholders.
4. Design practices for new facades that anticipate and accommodate the eventual need for
retrofit could facilitate future retrofit requirements. Facade systems should be designed to
facilitate the retrofitting of new materials and technology as developments occur.
5. Sustainable facade retrofit practices must be developed; a focus on material reuse is imperative
to avoid filling landfills with discarded facade materials, particularly glass.
6. New architectural glass recycling (not down-cycling) technologies are needed.
7. Advanced facade solutions using raw float glass should be pursued because of the
uncompromised material life and the
potential for easy recycling. Double-skin strategies may accommodate this in certain applications.
8. Costing models that factor in the environmental cost of damaging construction practices and the
true cost of energy are urgently needed to correct inaccurate perceptions of long payback periods
for energy efficient technology.

Building Enclosure Commissioning (BECx) is a quality-oriented process to enhance the delivery of a
new building or the retro-fit of an existing building in accordance with the Owner’s Project
Requirements (OPR). The process includes tasks to achieve, verify, and document that the
enclosure design and construction meets the expectations of the Owner and the performance
criteria identified in the Construction Documents (CDs). The BECx process is comprised of
numerous tasks and is performed during the standard phases of a project: Pre-Design, Design,
Construction, and Occupancy. The primary tasks include:
• Establishing a well-defined OPR and BECx Plan
• Verifying that the details and specifications meet the OPR through careful design reviews of the
CDs performed by a party knowledgeable in the detailing, performance, and construction
practices/installation of building enclosures
• Developing a building enclosure specification for inclusion in Division 1 of the Project Manual,
inclusive of project specific field testing
• Reviewing construction phase submittals and developing project-specific checklists
• Laboratory or field mock-up of building enclosure and testing to validate performance
• Periodic or ”milestone” observing, documenting and reporting of work during construction for
compliance with CDs
• Testing of assemblies throughout construction to validate performance
• Report for the building enclosure “close-out”
• Facility personnel training related to building enclosure operation and maintenance
