A PROPOSED TWO-STOREY RESIDENTIAL HOUSE USING AN ENERGY EFFICIENT DESIGN PROCESS FLOW CHART Site Survey -Determination of Location and Lot Area for the Proposed Two-Storey Residential Building Cost Estimate •General Requirements •Earthworks •Structural Works •Architectural Works •Plumbing Works •Electrical Works Design Calculations -Structural Analysis Drawings and Plans using Sketchup and AutoCad 2018 -Site Development Plan -Floor Plan -Elevations -Foundation Plan -Roof Deck Plan -Electrical Plan -Sanitary Plan Recommendation The process flow chart for the proposed two-storey residential house using an energy efficient design starts with the site survey by determining the location site and area dimension of the lot. Next, design calculations will be processed in order to determine the exact loadings and sizes of the needed foundations such as footings and columns. After the design, Sketch up and AutoCad 2018 will be utilized as tools for drafting of the plans namely: Site development plan, floor plan, elevations, foundation plan, roof deck plan, electrical plan, and sanitary plan. With all the available specification and designations in the plans, cost estimation will be done. These include the general requirements, earthworks, structural works, architectural works, plumbing works and electrical works. Finally, recommendation and feedback will be obtained based from the proposed design.
