II. The Triple Bottom Line Approach
Claire talked about the multiple benefits of keeping the existing wood roof structure of this 1950s house and actually exposing it as a vaulted ceiling in the remodel. We try to use the triple bottom line to make most of the decisions at Castaway House. In the case of the existing roof structure, the triple bottom line was design, budget and energy efficiency. In other cases, such as in design decisions having to do with kitchen cabinetry, it may be flexibility, universal design and recycled materials.
The point is, at the Castaway House, we’re not just looking at the typical bottom line – the budget. We’re looking to cultivate multiple benefits from everything we do.
III. Stack Ventilation Illustration
One of the benefits we get from exposing the existing roof structure instead of building a dropped ceiling is that it affords us a high vaulted space. Not only is this good in terms of the every day experience of the people who will be living there, but it provides an opportunity to put in place stack ventilation – an ancient passive cooling strategy explained below.Tags: architecture, blooming rock, budget, Cavin Costello, Claire Aton, energy efficiency, existing wood roof structure, operable skylight, phoenix, stack ventilation, taz loomans, The Castaway House, The Ranch Mine, triple bottom line, vaulted ceiling
