The Why Factory’s research design studio operates on the exchange of collective work and individual project. Implementing from the studio’s common framework, The Blockmaker, the studio’s research explores the notion of what makes a housing block? Through data to design approach and parametric software thinking, the Blockmaker is a research software that allows one to generate multiple design solutions by transforming mass, reconfiguration of programs, accessibilities, porosity and generating options for façade and structure responsively to a climate condition. My research question speculates on a scenario where a housing block would be self-sufficient with solar energy. How would it look like? How would it performs for power generation and at the same time generate better housing qualities for views, daylight and terraces? Can it create better qualities for a dwelling? In this studio, we add one parameter to observe the changes in our design intervention. In my case, for a block to be self-sufficient with solar panels, a parameter of energy demands with solar panel surfaces would be a primary aspect to consider. However, to make a housing block, it requires multiple parameters of housing qualities to finalise an optimised design decision.
