			The following sample application of STYL~IE shows the results of the RECC v2.5 model for global buildings [https://www.industrialecology.uni-freiburg.de/odym-recc].

			The upper figure on the right shows the different steps in the energy service cascade that are included in the STYL~IE accounting equations below, and the lower figure on the right shows sample results for the building stock in different regions.

			Most scenarios show substantial decoupling of per capita GHG for both scope 1+2 (energy supply) and scope 3 (material supply) for the building stock (STYL~IE figure on the right side). Despite growing stock levels, decoupling of energy-related GHG by reducing the energy consumption per built-up stock by half to two thirds and the GHG intensity of energy supply down to a small fraction of current values (STYL~IE figure with results, blue plots, left). Material-related GHG decline as well, driven by less inflow per stock (as stocks grow and construction declines) and a decline of the GHG intensity per ton of material supply by about two thirds (combined effect of more recycling/CE and less carbon-intensive primary production) (STYL~IE figure with results, red plots, right). Due to the high construction demand in some world regions (India chosen as representative region here), and the slow rise of low-carbon materials, the material-related scope 3 emissions are of similar size, and at times even larger, than the scope 1+2 emissions. This finding highlights the importance of including these embodied or ‘grey’ emissions in a consistent model approach of the building sector and require a policy debate on their mitigation

The accounting equations of STYLIE (see figure on the right) follow the scheme of the widely known [[wikipedia:I_=_PAT\|IPAT accounting equation]], as they expand the total pressure indicator into the different system variables, rearranging them to a decoupling factor for each stage in the energy service cascade.

	Each of the factors in the model equations has a distinct meaning. For example, the variable <math>C/S</math> denotes the material consumption <math>C</math> needed to expand and maintain a given in-use stock <math>S</math>. The indicator raw material input <math>RMI</math> per material production <math>MP</math> describes the dependency of material production on natural resources, whereas its complement, the recycled content <math>SC/MP</math> is a salient {{abbr\|Circular Economy\|CE}} indicator.
