Abstract:
The human population has been growing at least at the rate of 1.2% annually since 1960 reaching
up to 6.4B in 2002 and more than 7.0B in 2012. In Davao City, the annual population growth rate is running at 3.22% in year 1990, at 2.41% last 2007 and recently in 2013 at 2.36%. The alarming problem we confront today is that the increase in land area for human use does not expand in proportion to population density increase. It is the aim of this study to address the future problems on land and food shortage through the efficient integration of vertical farms on mixed-use multi-storied commercial-residential buildings in Davao City in order to provide income generating condominiums and produce organic crops for residents in an urban setting. The result of the computations showed that the integration of farms to mixed-use residential-commercial buildings in Davao City is highly feasible. The gross profit is highest using gross floor area percentage ratio combination of 50:5:20 for residential, commercial and vertical farm units respectively. (i.e., 50% of the building’s gross floor area should be allotted to residential units, 5% to commercial units, and 20% to farm units). Moreover the gross profit and ROI of the 50:5:20 gross floor area ratio
also generated the highest which amounted to Php 1,785,316,198.00B compared to only Php 501,045,100.00M for the typical commercial-residential buildings in five years. This research has mainly focused on the integration of hydroponics, but the inclusion of aquaponic farms in vertical structures can also be further explored.
Machine summary:
"It is the aim of this study to address the future problems on land and food shortage through the efficient integration of vertical farms on mixed-use multi-storied commercial-residential buildings in Davao City in order to provide income generating condominiums and produce organic crops for residents in an urban setting.
Statement of the Problem The purpose of this study was to determine the most economically efficient mixed-use ratio percentage of gross floor area needed when incorporating multi-storied farms in urban vertical structures to address food and land shortage problems, as well as transportation costs from having to deliver goods to urban centers, specifically it seeks to: a.
To determine the preferred hydroponic crops that can be grown in multi-storied vertical farms and the annual consumption of Davao City residents that can be included in the proposed mixed-use building structure?
b. To compute for the most efficient and effective gross floor area percentage of vertical farm that must be applied in the mixed-use residential and commercial ratio that will supply the required demand of preferred crops of the residents?
/ Fig. 2: Conceptual Framework MATERIALS AND METHODS The main goal of the study is to efficiently integrate farms in mixed-use commercial and residential buildings as a means to provide sustainable multi-storied structures in Davao City while maximizing land use and at the same time making the building beneficial to both the developers and tenants in such a way that it would generate greater income and would let them have a healthy comfortable and sustainable place to live."
