Introduction
Introduction
Objective
Explore and propose optimal design variants based on financial, environmental, and programmatic KPIs. This includes assessing the impact of different design choices on energy efficiency, cost-effectiveness, and urban integration.
Scope
Two plots in a dense urban neighborhood, requiring a balance between maximizing built-up area, maintaining environmental performance, and adhering to zoning regulations.
Key Focus Areas
Parametric workflows for flexible design exploration, building physics studies to optimize energy and daylight performance, and data-driven decision making to align with both financial and environmental goals
Approach & Methodology
Tools Used
Input Parameters: Plot dimensions, building types, constraints.
Main simulation environment utilizing EnergyPlus and Radiance engines to perform annual energy consumption and daylight simulations.
Single and multi objective optimizations, to find the most efficient solutions based on criteria like daylight exposure or energy consumption.

Revenue Calculation
Revenue Calculation
Net Profit = Price of Saleable Area + Price of Balconies (if there any) +Price of the corridor Area (if there Any)
Price of Saleable Area = Total Units Area * Form Factor * Price per sqm
Price of Balconies= Total number of Units* addition per unit price
Price of Corridor Area= Total corridor Area* Form Factor * Price per sqm
