[ca] Les normes que obliguen a la reducció en el consum energètic a les edificacions són cada vegada més estrictes, i tenen com a meta a mitjà termini, aconseguir edificis amb consum zero. L'actualització necessària dels edificis patrimonials enfronta diverses limitacions, ja que les normes de protecció redueixen les possibles intervencions, conduents a l'eficiència energètica i el confort dels usuaris. Aquest article presenta una metodologia replicable que identifica les tipologies d'envolupant profunda més utilitzades durant els inicis del Moviment Modern a Cali, les classifica segons les característiques geomètriques i determina les més representatives. L'objectiu de l'article és caracteritzar les tipologies existents i generar una classificació que es pugui utilitzar en el futur per determinar l'eficiència respecte a la qualitat de l'ambient interior en el clima càlid equatorial. Per definir la mostra intencional no probabilística, es va determinar un univers ampli i es va anar depurant amb criteris d'usos, alçades, any de realització i estat de conservació dels edificis. La definició d'uns criteris específics va permetre identificar les tipologies d'envolupant profunda utilitzades als edificis d'oficines construïts a Cali als anys 1950, es van classificar en 3 grups: amb elements verticals, elements horitzontals i combinació d'elements verticals i horitzontals. Finalment es van seleccionar els edificis que representen millor les envolupants profundes a Cali i que serviran com a casos d'estudi per identificar estratègies replicables en el disseny de façanes.

[en] The regulations that aim to reduce energy consumption in buildings are increasingly strict, and their medium-term goal is to achieve buildings with zero consumption. The necessary updating of heritage buildings faces several limitations, since protection standards reduce possible interventions, leading to energy efficiency and user comfort. This article presents a replicable methodology that identifies the most used deep-envelope typologies during the beginnings of the Modern Movement in Cali, Colombia. It classifies them according to their geometric characteristics, highlighting the most representative ones. The article's objective is to analyse existing typologies, creating a classification that can be used to determine their efficiency regarding indoor environment quality in hot equatorial climates. A wide review of data was used to define a purposive non-probabilistic sample, refined according to building use, height, year of construction, and conservation condition. These criteria allowed to identify the types of deep-envelope used in the office buildings built in Cali in the 1950s: with vertical elements, with horizontal elements, and with a combination of vertical and horizontal elements. Finally, the buildings that best represented the deep-envelope systems in Cali were selected and used as case studies to identify replicable strategies for the design of facades.
