GreenTRIP Sustainable Transport Building Certification Program

There are various ways to define building sustainability. A narrow perspective assumes that sustainable development simply means that buildings minimize energy consumption and climate change emissions, but a broader perspective recognizes that sustainability requires consideration of additional economic, social and other environmental impacts, such as lifecycle affordability, social equity, community integration, public health and safety, and land use impacts. In particular, even the most energy efficient building cannot be considered truly "green" if sited in an isolated location where access requires driving, and therefore lots of parking, and is poorly integrated into the larger community.

The US Green Building Council's Location and Planning Technical Advisory Group, of which I am a member, struggles with these issues. For example, we are working to define the specific requirements for walkability, bicycle parking and alternative vehicle incentives. It's amazing how much time we have spent defining the maximum bicycle rack and storage locker design, and the acceptable distance between bicycle racks and building entrances.

The GreenTRIP (Traffic Reduction + Innovative Parking) program provides a good model for consideration of transport and parking management in building location and operation. This program certifies new residential and mixed use developments that incorporate traffic and parking reduction strategies, with standards tailored to specific land use types. It was developed by TransForm (formerly the Transportation and Land Use Coalition), a San Francisco Bay Area smart growth advocacy group, with funding from the Bay Area Air Quality Management District, The Rockefeller Foundation and The Silicon Community Foundation.

Currently, all of the certified projects are located in the Bay area, but they have plans to expand to other regions such as San Diego and Sacramento starting this fall. Sign up for updates on GreenTRIP here.

Below are examples of certified projects with links to their GreenTRIP evaluation reports:

San Leandro Crossings is a mixed-used, multi-phase transit-oriented development located next to the Downtown San Leandro BART Station. The Crossings development includes Cornerstone, a 200-unit mixed-use residential project and The Alameda, 100 affordable homes. All parking spaces at Cornerstone will be unbundled and leased separately from the cost of housing.

The South Hayward BART Affordable Family and Senior Housing Project is a 206-unit, 3-5 story, mixed use apartment project next to the South Hayward BART Station. Eden Housing will offer two AC Transit passes at a 50% discount to each household for the life of the project.

Station Park Green is a 12-acre Transit-Oriented Mixed-Use Development in San Mateo, California. The project's program includes 599 residential units, office facilities, and carefully-crafted community-serving retail and restaurants. EBL&S is committing to provide a carshare pod on site and offer free carshare membership to all eligible residents for the life of the project.

Parker Place is a 155 unit mixed-used project in Downtown Berkeley. City Centric has committed to both unbundling parking from the cost of housing as well as offering two AC Transit Easy Passes with at least a 50% discount to each household for the life of the project.

 

These examples show that it is possible to develop truly sustainable buildings that incorporate efficient transport and parking management.
