Throughout history, utopian ideals have existed promoting nature as a necessary affect for better aesthetic and psychological being. Yet, as human populations climb so do stresses upon the natural environment - therefore, bringing "the city in harmony with nature" becomes more challenging. Fortunately, hope exists through the use of greenroof technology. Greenroofs are a green space created by continuous layers of drainage, protection, growing medium, and plants either onto or integral to a roofing system. This paper explores extensive greenroofs, characterized by low-maintenance and shallow growing medium. Greenroof benefits (ecological, economical, aesthetic, psychological) are classified as: Market and Human. Further exploration of human-driven benefits result in the definitions of active and passive sensation (the division of sensation): Active sensation is the immediate, present, unimagined engagement of a specific sense. Passive sensation is the imagined perception (sensing) of an object or element. As defined, Active Sensations are real and, therefore, have limits/defects/boundaries; yet, Passive Sensations are imagined, and therefore, limitless. As alluded by William James, "The philosophy which is so important in each of us is not a technical matter; it is our more or less dumb sense of what life honestly and deeply means. It is only partly got from books; it is our individual way of just seeing and feeling the total push and pressure of the cosmos." The remainder of the document explores human-driven greenroof design; emphasizing design as a form of inquiry. / Master of Landscape Architecture

As we move towards a sustainable future, designing technology plays a key role. Over the last few decades, the role of design has been steadily expanding from a purely economic benefit for products to a discipline that contributes to positive change for humanity. While the recognition of this responsibility is growing, there is a knowledge gap for design practice. What is a contemporary design approach and how does it translate into practice? We briefly review three major design movements (human-centred design, participatory design, design for sustainability) and introduce the human-driven design approach, which integrates all three perspectives into the design of technology. To explore the gap between human-centred design theory and design practice, we reflect on three use cases. Finally, this paper provides insights into how human-driven design can be implemented in practice and presents four key issues that require action: Stakeholder management, faster horses, prototyping for disruptive scenarios and methods for sustainability.
