Hamilton County 800 Building Earns LEED Certified Posted by admin on 01/1/15 in Building, Certified, LEED

The existing Hamilton County Juvenile Court facility, formerly the Times Star Reporter Building has recently earned the first Government Building Leadership in Energy and Environmental Design Certified Certification for Existing Buildings: Operations and Maintenance (LEED EB:O+M) certification in Ohio. This 19 story, 354,588 square foot building, constructed in 1937, has previously been renovated into governmental office and courtroom spaces.

Hamilton County has taken the initiative to implement new sustainable procedures for Sustainable Purchasing, Solid Waste Management, Integrated Pest Management and Green Cleaning. This EB:O+M Certification award recognizes that Hamilton County has successfully implemented exemplary performance in occupant comfort for the 685 full time occupants and the 100 average visitors to the building. The County has been a tireless proponent of sustainable ongoing purchasing, energy reduction and increased ventilation in its buildings. LEED also extended additional recognition to Hamilton County in its’ award due to the County’s reduction in mercury-containing lamp fixtures, use of low-flush water fixtures, new pollution source controls, and an increase in the usage of high performance cleaning equipment.

The Hamilton County Juvenile Court Building has shown a 28.1% reduction in potable water usage.  This reduction has resulted from reducing the buildings water usage to a level 21.16% below the LEED-EBOM baseline. The reduction is a result of strategic partnership alliances between the County, ThermalTech Engineering, GBBN Architects and THP Limited.  The building has consistently shown optimized energy efficiency performance with yearly Energy Star ratings consistently ranking between 86-88 from 2010-2014.  The Energy Use Index (EUI) for this building has decreased from 149.6 kBtu/sf to 141.7 kBtu/sf (201-2014).  The Green House Gas (GHG) Emissions have reduced from 3445.6 Metric Tons of CO2e to 3051.2 CO2e.

A major ASHRAE Level II Energy Audit was performed, during the latest round of Energy Conservation measures, for the baseline energy use for the natural gas, electrical and water systems.  This audit resulted in implementations of low, or no cost, energy efficiency measures including consolidation of server rooms, replacement of old HVAC equipment, lighting retrofits, new variable frequency drives, air balance retro-commissioning and a direct digital controls retro-commissioning.

As part of the standard LEED-EBOM required practice an “Enhanced Refrigerant Management and Emissions” procedure has been implemented and all Chlorofluorocarbons (CFC) shall be phased out of this building within 5 years.

This Hamilton County building has also been awarded three exemplary credits while demonstrating Innovations in their Building Operations. Sustainable purchasing forms show that 96.15% of the ongoing consumables purchased during the performance period were Sustainable. 100% of the cleaning products and 100% of the cleaning equipment used in this building have successfully qualified under the required sustainable criteria.

Finally the building qualified for three additional Regional Priority credits for low flow Plumbing Fixture installation, increased Energy Efficiency and increased Occupant Comfort.  Regional credits are those that are considered to be most important to the area.
