Beneficios económicos de la certificación LEED. Edificio Centro Ático: caso de estudio

This article discusses the economic benefits of the implementation of the sustainable building LEED (Leadership in Energy and Environmental Design) certification in the Centro Atico building located in Bogota, Colombia. Initially, the consumption of water and electricity are determined, as well as the costs of construction and operation of the building under its original design (built without regard to the parameters set by LEED). Then, strategies to allow the Centro Atico building to obtain the LEED GOLD New Construction V3 2009 certification are proposed and the economic increases associated with them are calculated. Also, the new consumption of water and electricity, when these strategies are applied (modified design), and their operating costs are calculated. Finally, indicators of economic goodness of investment are determined using a cash flow analysis.

Estudio técnico económico de alternativas del proceso de cimbrado y descimbrado en la construcción de un edificio de forjados de losa maciza de hormigón armado

El objetivo del presente trabajo es definir diferentes alternativas de procesos constructivos, estimando cuales resultan ser las mas beneficiosas respecto a su plazo de ejecucion y su coste, para un edificio de forjados de losa maciza de hormigon armado. Para resolver los plazos de ejecucion se plantearon tres alternativas del proceso constructivo: Cimbrado y Descimbrado; Cimbrado, Clareado y Descimbrado; y Cimbrado, Recimbrado y Descimbrado, considerado 2, 3 y 4 plantas consecutivas apuntaladas. Para evaluar que procesos son validos, primero se calculan las cargas que se presentan durante el proceso constructivo mediante el Nuevo Procedimiento Simplificado y posteriormente se comprueba si se cumple o no, en cada una de las operaciones constructivas, la condicion de descimbrado. Para el edificio objeto de estudio se han obtenido como procesos viables economica y tecnicamente los procesos constructivos de Cimbrado, Clareado y Descimbrado con 3 y 4 plantas cimbradas.
