Hotel Expansion & Renovation

Edgewater Hotel

Situated on the shoreline of Lake Mendota with views of both the lake and downtown Madison, this project included the renovation of the existing 1940s and 1970s hotel areas and a new grand hotel along with condominiums. The project also provided a large plaza area overlooking the lake that can be transformed into an outdoor skating rink in the winter. The existing underground parking garage was expanded and a new underground parking garage added to support the growing facility and area business.


New MEP systems replaced the existing aging systems and support new technologies and security requirements for the facility. A mechanical system consisting of high efficiency hydronic boilers and water-cooled chiller provide heating and cooling. The large occupancy areas, such as the banquet hall and ballrooms, are served ventilation air with demand control through the use of CO2 monitoring. This matches ventilation air to actual space occupancy to reduce energy use when the areas are not fully occupied. The facility also has a dedicated outside air unit that uses energy recovery to pre-treat the outside air with the conditioned air being exhausted out of the building. Four-pipe fan coil units provide the individual temperature control for the guest suites and condominiums. A new indoor spa and fitness area including an indoor pool (all served by new MEP systems) was added to the 1940s building.


A new commercial kitchen replaced the existing Rigadoon Room and supports the outside dining area.


Lighting throughout the renovated area was upgraded to enhance the space and improve efficiency by reducing energy consumption through improved fixtures, lighting control, and occupancy control. Conference areas have multi-level switching control to allow for various space functions as needed.


The new hotel tower includes a large banquet hall and gathering area; a grand staircase is used to showcase this building and banquet facilities. Individual guest rooms are located on the upper floors with the top two floors housing condominiums.

Technology systems include voice/data/CATV structured cabling, video surveillance, audio/visual systems, and technology grounding/bonding infrastructure.
