[웹페이지]역사적인 건물를 위한 에너지

역사적인 건물에 신재생에너지를 도입하거나, 에너지를 합리적으로 사용하기 위한 프로젝트가 있다. 이름하여 New4Old Project! 이를 운영하는 사이트 주소는 http://www.new4old.eu/ 이다.

New energy for old buildings

Promoting the integration of RES & RUE measures in historic buildings

Project Description

The
project New4Old is committed to significantly contribute to Renewable
Energy Sources (RES) & Rational Use of Energy (RUE) market
penetration in historical buildings through a two-fold approach:

  • Creation of a network of Renewable Energy Houses
    (REH) which will serve as focal points for the sustainable energy
    policy discussion in the different EU Member States & contribute to
    the commercialisation of RES & RUE equipments.
  • Capacity building among architects and planners
    through guidelines and training activities in the field of building
    integration of renewable energy and energy efficiency into historic
    buildings. Inspired by the success of the REH in Brussels, it is the
    intention of this project to lay the ground for the creation of publicly
    accessible REH lighthouse projects, which will serve as a base for
    further stimulation of the market replication of RES & RUE
    technologies in the respective countries. All REH of the network will
    always feature the latest renewable energy and energy efficiency
    technologies available and will serve as demonstration projects for the
    proposed communication and marketing activities.

Project Duration

September 2007-September 2010

gbXML

사용자 삽입 이미지gbXML이란?

The Green Building XML schema, referred to as “gbXML”, was
developed to facilitate the transfer of building information stored in
CAD building information models, enabling integrated interoperability
between building design models and a wide variety of engineering
analysis tools and models available today. Today, gbXML has the industry
support and wide adoption by the leading CAD vendors, Autodesk,
Graphisoft, and Bentley. With the development of export and import
capabilities in several major engineering modeling tools, gbXML has
become a defacto industry standard schema. Its use dramatically
streamlines the transfer of building information to and from engineering
models, eliminating the need for time consuming plan take-offs. This
removes a significant cost barrier to designing resource efficient
buildings and specifying associated equipment. It enables building
design teams to truly collaborate and realized the potential benefits of
Building Information Modeling.
