Final Architectural Design Studio Design Of Davao City Vertical Housing With Nearly Zero-Energy Building And Biomimetics Concept On Building Envelope

Abstract

Davao City is a 1st class highly urbanized city in the island of Mindanao. it was populated 1,632,991 based on the 2015 census. This translates to an average of four persons per household. The annual population growth rate is at 2.3% in 2015. This result as an issue related with spatial availability, especially in several locations at the center of the city like Bucana. This area is now very dense due to the increasing number of migrants living in the area. Therefore, a vertical dwelling is needed to accommodate this increase in population. Based on data from the World Green Building Council one of the largest energy user sector is occupancy sector, energy consumption in the occupancy sector is dominated by electrical energy that is 71 percent of total energy consumption in 2013. The amount of energy consumption only includes energy activity in residential buildings. It proves that in the post-occupation phase and building operations, residential buildings consume tremendous energy. The problem arises due to the high cost of living in a housing mainly because of the energy usage, to achieve low expense housing it needed Low Energy Consumption to lower the energy usage. This concept aiming so that the energy fulllment of buildings can be suppressed and the residents there can improve their standard of living by getting housing that is low expense and livable. One of the strategy of reducing energy is by using building envelope mainly to minimize the usage of air-conditioning and articial lighting, by using Biomimetics as a approach that relies on the building envelope for function. The main function of the building envelope is to provide the interior space with an external shading system throughout the day allowing natural daylight and minimal heat. The application of the Biomimetics approach on building envelope hoped that will become a building advantage and enhance housing quality in Davao City.
