LEED Gold 2011

The Mulvaney Medical Office Building is the first LEED® Gold certified Core and Shell project in Idaho.

The three-story 70,000 square foot Mulvaney Medical Office Building, located on the Saint Alphonsus Regional Medical Center campus, faces a major highway (I-184) and is viewed by thousands of daily commuters as they travel into and out of Boise’s downtown area.
 
The Mulvaney Medical Office Building is the first LEED® Gold certified Core and Shell project in Idaho. The building incorporates high-performance glazing, an energy-efficient building envelope and lighting systems, water-efficient fixtures, durable and low-maintenance building materials, and non-toxic finishes.  
 
A 2,500 square foot second-floor roof garden is filled with drought-tolerant native and adapted plants, grasses, wildflowers, ground covers and trees. Translucent skylights on the third floor and exterior shading devices on the west, east and south elevations provide 13% of modeled energy savings. 84% percent of the construction waste was recycled locally, and 35% of construction materials were acquired within 500 miles of the project site. 64% percent of the materials contained recycled material, and 90% of wood products were harvested from FSC-certified forests.
 
During design, the University of Idaho Integrated Design Lab in Boise conducted analysis of the exterior shading devices, roof skylights, and interior day lighting strategies for the building. This analysis translated into an energy savings reimbursement through the local power company.
 
The original goal of the project was LEED® Silver certification. Through construction the owner saw LEED® Gold as being attainable and revised the goal.
 
The project’s sustainable commitment extends to each tenant improvement development within the building. Through lease agreement tenants were required to: use water-efficient fixtures, non-toxic materials and carpet, and energy efficient strategies including daylight harvesting in their tenant improvements.
 
During design, several mechanical systems were evaluated for energy efficiency, life cycle cost analysis, and initial cost including a ground source heat pump system. It was determined that a ground source heat pump system would not be cost effective for this scale project. The building could be connected to a geo-exchange system if developed in the future.
 
A motivated owner who wanted to develop a LEED building engaged a LEED experienced design team and LEED experienced contractor to provide integrated project support. The contractor provided cost estimating, value engineering, and constructability direction and provided several key subcontractors for ‘design assist’ during the document phase of the project. The net benefits were seen in a financially successful project as well as a project that over-achieved its goals.
