255 Alhambra Circle

Coral Gables, Florida


255 Alhambra, located in Coral Gables, Florida, is a building consisting of mixed office space originally constructed in 1974. In November 2017, the 228,188 square foot building was certified Leadership in Energy and Environmental Design (LEED®) Gold by the U.S. Green Building Council utilizing Transwestern’s LEED for Existing Buildings: Operations and Maintenance™ v2009 Volume Program.

Challenges and Solutions

255 Alhambra utilized Rivion’s in-house commissioning team to perform an ASHRAE Level II audit for Existing Building Commissioning – Investigation and Analysis. As part of the ASHRAE Level II audit, Rivion created a breakdown of energy use in the building, performed a savings and cost analysis of all practical measures that meet the owner’s constraints and economic criteria, and discussion effects on operations and maintenance procedures. Existing Building Commissioning – Implementation was also pursued to implement all no- or low- cost items and to create a capital plan for major retrofits and upgrades.

255 Alhambra is implementing an Indoor Air Quality (IAQ) Management Plan based on the Environmental Protection Agency’s (EPA) Indoor Air Quality Building Education and Assessment Model (I-BEAM). The IAQ Management Plan aims to manage major sources of indoor pollution in buildings such as remodeling and renovations, painting, pest control activities, shipping and receiving, moisture and mold. Additionally, the plan establishes procedures for receiving and responding to building occupant feedback regarding IAQ.

A challenge faced during the recertification project was garnering participation from all office tenants. Building ownership and the on-site management team implemented a tenant engagement program to account for occupant preferences. This program is likely to increase employee satisfaction with their working environment and encourage them to take interest in the building’s long-term sustainability goals.
