Parsimonious process model of energy retrofit of buildings

Abstract

Building information modelling (BIM) technology has been focusing on the creation, sharing and use of a comprehensive digital twin of the facility under construction or renovation. It is believed that a more comprehensive, structured and complete model would be better. The aim of this paper and the underlying research is to reaffirm the view that the essence of information is to inform the user and that the main purpose of information models is that they are informative – that they contain the necessary information. Parsimonious information is information that is necessary but as simple as possible. Our hypothesis is that in many cases simpler models could be more useful, as they do not introduce technological barriers with the usually involved low- and medium-level contractors. One such case is the energy retrofitting of existing buildings. Many public and residential buildings with poor energy performance are located all over the world, especially in Eastern and Central Europe, as well as in China. They are an efficient target for a significant improvement in their energy performance by improving the building envelope and openings. The paper presents an economical process model for the modernisation of existing buildings. This model provides a basis for a parsimonious product model, which is currently under development. The broader objective of the research presented is to examine cases where a heavy information model may not be necessary and where a detailed process definition – as described in the BIM implementation plan and related documents – would lead to over-specification that would limit the free dynamics of a workflow.

Secondary abstract:	Tehnologija informacijskega modeliranja stavb (BIM) se osredotoča na ustvarjanje, izmenjavo in uporabo celovitega digitalnega dvojčka objekta, ki se gradi ali prenavlja. Menijo, da bi bil celovitejši, bolj strukturiran in popoln model boljši. Namen tega prispevka in raziskave, na kateri temelji, je ponovno potrditi stališče, da je bistvo informacij obveščanje uporabnika in da je glavni namen informacijskih modelov, da so informativni - da vsebujejo potrebne informacije. Parsimonične informacije so informacije, ki so potrebne, vendar čim bolj preproste. Naša hipoteza je, da bi lahko bili v številnih primerih preprostejši modeli bolj uporabni, saj ne uvajajo tehnoloških ovir z običajno vključenimi izvajalci na nizki in srednji ravni. Eden od takih primerov je energetska prenova obstoječih stavb. Veliko javnih in stanovanjskih stavb s slabo energetsko učinkovitostjo je po vsem svetu, zlasti v vzhodni in srednji Evropi ter na Kitajskem. So u činkovit cilj za znatno izboljšanje njihove energetske učinkovitosti z izboljšanjem ovoja stavbe in odprtin. V članku je predstavljen ekonomski model procesa za posodobitev obstoječih stavb. Ta model je osnova za enostaven proizvodni model, ki se trenutno razvija. Širši cilj predstavljene raziskave je preučiti primere, v katerih težak informacijski model morda ni potreben in v katerih bi podrobna opredelitev procesa - kot je opisana v načrtu za izvajanje BIM in povezanih dokumentih - vodila v pretirano specifikacijo, ki bi omejila prosto dinamiko delovnega procesa
