• Extending the unit-related geometry into an addition that doubles the size of the building called much attention to itself and started to present a clear challenge to the historic building fabric. We found ourselves trying to bury or lower the addition at every turn to minimize its impact and the loudness of the geometry.

• When continuing the unit-related geometry, we fell into many of the similar geometrical complications created by this geometry. Triangular rooms and 60-degree corners present particularly difficult challenges in the realms of furnishings and flexibility.

• When our peers (architectural historians and critics) reviewed the previous unit-related designs, a consistent concern was raised: Why are you following the same geometry? Doesn’t this mimic too closely work of Frank Lloyd Wright? These peers have seen many additions done to historic buildings and the most successful response across the planet is to make a clear departure from the original architecturally and geometrically.

• The curve was the simplest and the quietest gesture we could make in response to the intense geometry already present on the site. The curve is largely read from the sky. It is almost unperceivable when you first enter the site. On the ground it is a soft and subdued form that lightly touches the upper B-wing.

• A curve always refers itself back to its origin. Here, the curve is generated from center points within the Meeting House and therefore, is always tied back to it. At just about every point in the Crossing, a line of structure or architectural feature leads your eye back to the Meeting House. In this way the curve is self-denying. We felt that this was an appropriate poetic gesture for an addition on this site to make. The curve reinforces the iconic power of Wright’s landmark.

Why did we choose a curve?

System is shown in heating mode. During the cooling season, chilled water flows through the

same cycle.

Air Handling Unit #2

Air Handling Unit #1

Geothermal SystemsThe second phase for building thermal comfort is to utilize the radiant heating and cooling floor system.

In this system, water cycles through the geothermal wells and into the heat pump/chiller, which provides hot water for heating and chilled water for cooling. Tempered water is then piped throughout the building to air handling units and radiant flooring systems. After it has done its job, the water returns to the heat pump/chiller unit and the cycle begins again.

CO2 sensors in the spaces detect when they are occupied, which energizes the mechanical air systems to supply the required amount of fresh air.
