That’s a well-designed lot and very cool green-roof building indeed! I would love to work there! But it serves a very different context and real-estate economics than the high-density examples linked by Troupo. A suburban insurance HQ in a mid-sized city doesn't face the same constraints as a retail hub in a capital. The target demographics and land pressure aren't comparable.

In your example, they could have likely built the solar array on the large lawn to the north for much cheaper and with easier maintenance. The fact that they chose this integration suggests that cost was secondary to corporate signaling and employee experience [0]. For most parking lots density isn't a design choice, it's a financial necessity.

The one I was talking about (still on construction) targets a working class suburb. The few trees were tightly packed between the parking spaces and the new roof's supports are as well placed mostly in-between spots. They cuter the tree because the shade and the impossible maintenance. The shaded rosebush were kept but are now dying.

edit [0] Indeed, the roofs are part of their "Transition Plan" > As a key part of our ambition to consume 100% renewable electricity, Aviva has taken a significant step by installing a 1MW wind turbine at its Perth office in October 2024 In combination with our existing solar car ports and rooftop solar, the turbine will fully power the Perth office with 100% self-generated renewable energy for the majority of the year. It is expected to generate 1,700MWh annually, the equivalent to the electricity required to power over 620 homes. https://static.aviva.io/content/dam/aviva-corporate/document...
