Green Retrofit Design(GRD)

Purpose to eliminate negative

environmental impact completely

through skillful, sensitive design

(McLennan, 2004)

Green building(also known as green

constructionor sustainable building)

refers to a structure and using process

that is environmentally responsible and

resource-efficient throughout a buildingslife-cycle: from siting to design,

construction, operation, maintenance,

renovation, and demolition. This requires

close cooperation of the design team,

the architects, the engineers, and the

client at all project stages (EPA, 2012).

GR refer to incremental

improvements

to the building fabric and systems

with the primary intentionof

improving energy efficiency and

reducing carbon emissions(Rhoads,

2010).This definition excludes disruptive

refurbishment that would require

the building to be vacated for

an extended time, behavioural

training programmes and

space rationalisation or utilisation.

GBD vs GRD

TEXT TEXT TEXT TEXT

Standpoint GBD model BIM facilitated GRD modelCommunicative intent

(semiotics)

To site study and document the information from pre-

design, construction, post-design

(to extend the project ideas for the realisation)

To standardise data structure used for the exchange of

building information

(to specify data structures for the information exchange)

environmental values of energy efficiency

The roles in the projects have different professional

backgrounds. (Cerovsek, 2011) Vendors of software

presenting the process maps, function and behaviour of

buildings.

Authoring environment

(encoder)Capture software include ImageModeler, Project

Photofly, Global Link, Pictometry Online and PKNail

Silo energy analysis tools such as Ecotect, Project

Vasari, VE-Pro, Energy Plus, DOE2, TRNSYS with design

optimization from aspects Building Orientation and

Shape, Rational Planning Space and Control Shape

Coefficient, Daylighting design etc.

BIM tools software packages with GBS (Green Building

Studio), Ecotect, Project Vasari, VE-Pro, Energy Plus,

DOE2, TRNSYS these well- developed energy analysis

tools. Design-Design (DD) as-design Model, Design-

Construction (DC) as-construction Model and Design-

Operations (DO) as-built Model are created.

Modelling constructs

(code)Calibration process to optimize model and measure

parameters to contribute the simulation for providing

more accurate estimation of annual cost saving

associated with DCV (Demand-controlled Ventilation)

Milestones for technology development in BIM would consider to be taken places in between time of 1970, 1985,

1993-1995, end of 1990s until now (Moum, 2010).

As early as 1970, according to Howard and Bjork, as product modelling was once introduced.

Then since 1985 to mid-1990s, came with ISO (Standard for the Exchange of Product Data) in the application of

some European and German research projects.

From 1993 to 1995, after gaining the projects experiences from the COMBI, the industry consortium IAI

(International Alliance for Interoperability) took over the AEC industry for the product modelling standardization.

Finnish research activities including VERA programme in 2006 were in good effort in developing IAI then the well-know IFC (Industry Foundation Classes).

AIA introduced the Brand BuildingSMART in June 2005 for integrating technologies 3D object-based modelling and

BIM in the AEC industry.
