Green Building Certification, A Common Sense Approach

Halstead outside

As Director of Sustainability for JL Architects, I am active as both a Green Globes Professional and Green Globes Assessor for the Green Building Initiative (GBI).  I recently had the pleasure of completing the Green Globes Stage II Verification for the Halstead International’s new warehouse in Rincon, GA, and proudly share that the project successfully achieved 2 Green Globes!

Wondering what this means?  Follow along with this (very!) condensed version of a Green Globes Stage II Report, and learn if a Green Globes building certification is the right solution for your next project.

Green Globes Report (condensed)

The Halstead warehouse is a new construction project consisting of a 153,000-square foot, single-story warehouse with a two-story office space built within. The warehouse is a structural steel frame building with a concrete tilt up exterior wall system, aluminum storefront, and membrane roof.  It is used as a warehouse facility, to serve the customers of Halstead International.

The Green Globes Stage II verification process included an on-site assessment.  During the assessment, I completed the following: a physical review of the completed building, interviews with members of the design and construction team who were responsible for the management of the project, and a review of product submittals and documentation. This allowed for me as the Green Globes Assessor to verify the targeted achievement defined by the project team, and as confirmed in the Construction Documents.

The onsite assessment was performed on January 25, 2018 beginning at 9:30 am.  The following people accompanied me on the assessment:

  • Jonathan Stone, Vice President of Operations, Halstead New England
  • Rowland Davidson, Randall Gipson, and Steven Barthlow of Lynman Davidson Dooley Architects
  • Bryon Payne, Building and Site Manager

Discussions focused on substantiating the points from the online self-evaluation using the construction documents, records of the design and construction processes, specification sheets, shop drawings, logs, meeting minutes, reports, computational models, and other relevant information.  At 10:30, the facility was toured to verify installation and implementation of the features.  Following the tour, a closure meeting was conducted with Jonathan Stone to review the tentative results of the assessment and identify additional information required to complete the Stage II verification process.  The tour concluded just in time for the 12:00 Ribbon Cutting Ceremony.  During the Ceremony, the Halstead organization shared their commitment to sustainability.

The methodology used to derive the final score was to assess the criteria within each of the following project elements:

Project Management

Meeting minutes were provided to reflect initial and final performance goals. Qualitative values and metrics were provided in the energy model summary data to demonstrate green design, as well as performance goals for electricity, and the use of the solar panels producing onsite renewable power.


The Hydrology report includes calculations to demonstrate that the site meets municipal water quality targets and is designed to retain 50% of the total average rainfall volume.

The technical information was provided for the UltraPly TPO Membrane roof including the Radiative Properties such as solar Reflectance at .79/.68.

Existing large trees were integrated into the surrounding landscape, while the new landscaping  combined with the existing native surroundings assures plants are non-invasive and drought-tolerant.

An energy model was created using ASHRAE 90.1 2010 Appendix G and was used to assess the future energy performance. The provided model summary indicates that the energy costs and consumption to be 63% compared to the reference base building.

On-site Renewable Energy – A study was conducted to determine the technical feasibility and cost effectiveness of on-site renewable energy. The recommendations of the study were partially implemented resulting in rooftop Solar panels and controls.

Contributing to the reduction of potable water demand, the Toilet fixtures have a 1.28 GPF, and lavatory faucets have a flow rate of .5 GPM. The landscaping does not use irrigation.

 Materials and Resources

Shipping containers were salvaged and refurbished for use in the design of the office area interior and exterior skin. The shipping container doors are welded open to form sunshades. The reception desk incorporates reclaimed shipping pallets. Decorative mobiles are installed in the reception area and are made of reclaimed wood flooring.

Reports were provided to verify over 75% of construction waste was diverted from the landfill. 120 tons of concrete was hauled off the site to be crushed and reused.

Ozone-depleting Potential – R-410A (which contains only fluorine) does not contribute to ozone depletion. Heating and cooling roof top units are capable and equipped with leak detectors.

Indoor Environment

Between 50-74% of the floor area occupied for critical visual tasks achieve a minimum daylight factor. Between 31-59% of task areas have views to the exterior. 149,400 SF of daylit area uses photo sensors.

The warehouse has louvers on the north side of the building. Fans are installed for air circulation as per ANSI/ASHRAE 62.1-2010. All operable openings are readily accessible to the building occupants.

Verification by the assessor resulted in a final score of 486 out of 836 applicable points, which equates to 58.1% and a Two Green Globe rating for the Halstead Warehouse Rincon, GA.  This level of sustainability is a notable accomplishment!
