New Quincy Center Redevelopment

SERVICE:

GHG and Mesoscale Analysis

DESCRIPTION:

Tech Environmental, Inc. prepared air quality and greenhouse gas (GHG) studies of the New Quincy Center Redevelopment. The work was conducted in compliance with the M­EPA GHG Policy and Protocol and with the Certificate on the EENF. The scope included 10 design blocks which www.chattime.me ­contained 15 distinct buildings, all of which will contain mixed uses.

As part of this project, Tech performed a mesoscale air quality analysis for volatile organic compounds (VOC), oxides of nitrogen (NOx), and carbon dioxide (CO2) in accordance with Massachusetts Department of Environmental Protection's (MassDEP) guidelines. The EPA MOBILE6.2 model was used to calculate VOC and NOx motor vehicle emission rates for the average daily traffic speeds. These emission rates were used to calculate total VOC and NOx emissions in the study area for six analysis cases. Since the Build case VOC and NOx emissions will exceed those for the No-Build case, a mitigation analysis was required. All "reasonable and feasible" TDM measures and roadway/traffic signal improvements were presented, and to the extent possible, the benefits will be quantified.

Tech also performed an energy and carbon dioxide (CO2) emissions GHG analysis for the 15 buildings in the Quincy Center Redevelopment Project. Energy use and CO2 emissions were calculated for two cases: a building code-compliant Base Case, and the Preferred Mitigation case. Tech worked with the design team to consider lower energy-intensity alternatives in the building design, its lighting and mechanical equipment, and transportation to the site.

Tech summarized this work in the GHG report Draft Environmental Impact Review (EIR) to help attain a MEPA Certificate for the project.
