Web Usability 4 Summary:
Daylighting and perimeter visual environment System maintainability Material durability Beyond these major performance issues the following more specialized building performance topics are covered by separate authors in concert with the principal system authors and, where appropriate, integrated into the main text for each system: The Whole Building Design Guide www.
Accordingly, the WBDG covers the whole range of today's issues in building design, such as sustainability, accessibility, productivity, and safety—both from human and natural hazards.
The WBDG is constantly augmented with updated and new information and is structured as a "vertical portal", enabling users to access increasingly specific information as they navigate deeper into the site.
The concept of the Whole Building Design Guide has been formalized to achieve four main goals: To simplify access to government and non-government criteria and standards information using a web-based approach so that valuable time is not wasted searching for this documentation.
To replace outdated, redundant paper-based criteria documents.
To provide a brief, up-to-date and informative resource that covers general and specific topics in an encyclopedic form. However, unlike a traditional encyclopedia, the WBDG enables the user to build up a private store of relevant information by direct links to other resources available on the Internet with a few mouse clicks.
The WBDG has become a primary gateway to up-to-date-information on a whole range of Federal and private sector building-related guidance, criteria and technology from a "whole building" perspective. Users are able to access information through a series of "levels" by way of three major categories: At a lower level are Resource Pages, which are succinct summaries on particular topics written by experts.
Pages within the WBDG are cross-linked to each other, and hyperlinked to external Web sites, publications and points of contact, allowing easy access to related information.
Agency-specific information is accommodated in a Participating Agency section. Other features include relevant Federal mandates, news headlines and a robust search engine. A Board of Direction and Advisory Committee, consisting of representatives from Federal agencies, private sector companies and non-profit organizations guide the development of the WBDG.
The Evolution of the Building Envelope The Building Envelope Design Guide will constantly evolve, with its users participating in this evolution rather than simply using a set of fixed, definitive guidelines.
They will thus be advancing the evolution of the building envelope itself.
The first building envelope that protected humans from the elements was probably a cave that provided a degree of privacy and security. The earliest building envelopes were dome-shaped structures that combined wall and roof Figure 2A.
At an early stage, however, the two dominant forms of envelope evolved, depending on climate and available materials: Early shelters in the warm climates of Africa and Asia used timber or bamboo frames clad with leaves or woven textiles.
In other regions and climates heavier indigenous materials such as stone, rock and clay baked by the sun were used to provide more permanent shelter and protection from the heat and cold Figure 2D. To this day rural regions in lesser developed countries still construct these forms of shelter.
In the developed world we still use envelopes of timber frame and masonry walls, although both have evolved into a wide range of materials—some natural, others synthetic. Roofs evolved independently as waterproof elements with their own set of materials.
Steps in the evolution of the building envelope: Thus, eventually the roof, wall and floor became distinct elements of the building envelope that have continued to this day with very little change in concept, use and even material.
A medieval dwelling might have walls of wood, brick or stone, a wood roof structure, a slate tile or thatch roof and a floor of stone or hardened dirt.
Such a dwelling can still be found today in many regions of the United States and the world. To take one element of the envelope, the wall, its basic performance requirements have remained the same from medieval times to this day: However, our expectations have vastly increased, both in terms of absolute performance and the ability to control the impact of exterior water, sunlight and the ambient outside temperature on our interior environment.
Depending on a society's structure and economy, such needs as degree of permanence of our exterior system, its scale and adornment and our desire to have a wide variety of exterior envelope choices may also vary considerably.Beyond this thorough instruction in design, Durkin's Expert Systems outlines the steps required to introduce, implement, and manage an expert system project in the workplace--in a chapter that covers choosing a project, obtaining management approval, testing the system, and maintaining the system.
This book is a combination of introduction 5/5(6). Design Systems—also known as 'pattern libraries' or 'component libraries'—promote quality, consistent UX design across products; and expedite the work of designers, developers, and anyone else working on a website, application, or any digital design.
General Responsibility Assignment Software Patterns (or Principles), abbreviated GRASP, consist of guidelines for assigning responsibility to classes and objects in object-oriented pfmlures.com is not related to the SOLID design principle..
The different patterns and principles used in GRASP are controller, creator, indirection, information expert, high cohesion, low coupling, polymorphism. Quality System Regulation 21 CFR Basic Introduction Basic Introduction Kimberly A.

Expert systems are designed to solve complex problems by reasoning through bodies of knowledge, represented mainly as if–then rules rather than through conventional procedural code. The first expert systems were created in the s and then proliferated in the s.
