Final answer:
To choose the better environmental option between design alternatives for the Brew House with an added timer, one must compare their environmental impact factors such as energy use, resource usage, waste, and lifecycle impact, considering the identical revenue and costs of the Brew Master's timer.
Step-by-step explanation:
To determine which design alternative is the better environmental choice for the Brew House, assuming that the timer added to the Brew Mini model has revenue and costs identical to those of the Brew Master, one would need to analyze various environmental impact factors such as energy consumption, resource usage, waste production, and lifecycle impact.
If the additional cost and environmental impact of embedding a timer into the Brew Mini are lower while providing equivalent functionality, it might be considered a better environmental choice.
It is important to consider both the direct environmental impact of manufacturing and using the timer as well as any potential environmental benefits that might be derived from the timer's use, such as reducing energy consumption by brewing only as needed.
