Green Globes is a well-established green building guidance and assessment program that offers a practical and affordable way to advance the environmental performance and sustainability of a wide variety of building types.
I currently had the pleasure of completing the Green Globes for New Construction (Green Globes NC) Stage II Verification for the Greater Cleveland Regional Transit Authority’s E.105th-Quincy station platform located in Cleveland, Ohio, and proudly share that the project has the potential to successfully achieve 2 Green Globes!
It is a policy of the Greater Cleveland Regional Transit Authority to incorporate sustainable and green building principles throughout their facilities. An Eco-Charrette was conducted at the on-set of the project to determine what certification type would be best suited for the project.
The project team found that LEED has a mandatory minimum square footage requirement. The minimum requirement for New Construction is 1,000 sf. The station building is only 355 sf and does not meet the minimum program requirement for LEED Certification. Green Globes was found to be an attainable and practical approach for this project.
GCRTA Platform On-site Assessment Highlights
The project includes a 355 square foot building consisting of an elevator, machine room and electrical room situated on a 3,758 square foot platform. The station services commuters arriving to and departing from E 105th and Quincy Streets in Cleveland Ohio.
During the onsite assessment the following was completed: interviews with members of the design and construction team responsible for the management of the project, a review of product submittals and documentation, a tour and physical review of the completed renovated space. 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.
Discussions focused on substantiating the points from the online self-evaluation referring to construction documents, records of the design and construction processes, specification sheets, shop drawings, logs, meeting minutes, reports, computational models, and other relevant information. The facility was toured to verify installation and implementation of the features. Following the tour, a closure meeting was conducted to review the tentative results of the assessment and identify additional information required to complete the Stage II verification process which will be provided by the project team.
The methodology used to derive the final score was to assess the criteria within each of the highlighted following criteria:
Meeting minutes were provided to reflect initial and final performance goals. Qualitative values and metrics were provided in the Construction Documents to demonstrate green design, as well as performance goals for energy, water and indoor air quality. Qualitative values and metrics were provided in the energy model summary data that demonstrate performance goals for electricity.
The Integrated Design Process was employed, which included a minimum of five of the key design disciplines involved in the project.
Heat Island Effect – In addition to the roof plan and specifications included in the construction documents, the technical information was provided for the R-Mer metal roof system such as solar Reflectance at .84, Light-colored concrete was specified and installed for paved surfaces which provides high SRI. Due to the orientation of the building and platform, between 25-49% of paved surfaces beyond the building footprint will be shaded by structure above.
Shaded Surfaces Year-Round
Public Multi-User Bike Path
Energy Efficient Transportation – According to Neighborhoodscout.com – more people ride the bus in this neighborhood each day to get to work than 95.4% of U.S. neighborhoods. The site is located within 0.25 mi of the bus line 318 providing public transportation and the site is located within access of a public bike path.
An energy model has been performed using Trane Trace 700. ASHRAE Standard 90.1-2010 Appendix G has been used as a reference to complete the energy model. Based on the Trane Trace 700 energy model, the proposed building has an economic cost improvement over the baseline building of 30.68%.
Green Globes Water Calculator results project >39% reduction of water use compared with Baseline water use. If fact, there is no water used on the site.
Materials and Resources
Environmental Product Declarations for the applicable core and shell materials: Concrete and steel make up the largest percentage of materials selected for the building core and shell. Industry wide EDP’s are commonly available for at least 10-24%.
Construction Waste – Reports will be provided to verify over 75% of construction wasted was diverted from the landfill.
Operational Waste – the on-site Assessment confirmed the storage areas for points of waste handling, service and pick up areas.
Storage Area at Point of Service for Recyclables
Materials Allow Modular Sizing of Openings in Walls
Ozone-depleting Potential – R-410A (which contains only fluorine) does not contribute to ozone depletion.Global Warming Potential – However, R-410 has a high GWP (1700 times the effect of carbon dioxide), like that of R-22.
Volatile Organic Compounds – Interior and exterior latex as well as Concrete & Masonry Primer paint contains low VOC. Moisture and Vapor Control Methods – Humidity and moisture control are accomplished using the split system heat pumps and the split system air conditioners. The split system design is used to maintain humidity at an acceptable level.
Pest and Contamination Control – Outdoor air inlets have bird & insect screens as part of standard construction of louvers.
Other Indoor Pollutants – Signage is provided to indicate No Smoking on the premises.
Daylighting – The elevator is the occupied space and receives 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.
Verification resulted in a final score of 383.5 out of 690.5 applicable points, which equates to 55.5% and a Two Green Globe rating for the GCRTA Platform station, in Cleveland, Ohio. This level of sustainability is a notable accomplishment!
