Bikers need wheel benders like a fish needs a bike lock. In LEED v4, bike rack quality is a requirement. Photo Credit – forkergirl, via Flickr, Creative Commons LicenseThat question has been asked under past versions of LEED, and LEED v4 provides an answer. If you're pursuing this credit, plan not only to provide bike storage and changing facilities, but also to ensure that the project is connected to a "bicycle network"—bicycle trails or lanes that connect, within three miles bicycling distance, to at least 10 diverse uses, a school of employment center, or a transit stop.
LEED v4 has rewritten the calculations used to determine the number of bike racks and changing facilities required for projects, and introduced the concepts of short- and long-term bike parking.
Short-term bicycle storage must be within 100 feet (30 meters) walking distance of any main entrance. Long-term bicycle storage must be within 100 feet (30 meters) walking distance of any functional entryAn entryway that is designed to be used by pedestrians and is open during regular business hours. This does not include any door that is exclusively designated as an emergency exit, or a garage door that is not designed as an entrance for pedestrians.. That allows LEED v4 to provide finer-tuned requirements, as follows.
Whereas LEED 2009 required storage for 5% of all users measured at peak periods, LEED v4 requires only 2.5% coverage with short-term bike parking, while requiring 5% coverage for regular building occupants with long-term parking. In each case, a minimum of four spaces must be provided on all projects.
Rather than requiring changing facilities for 0.5% of full-time equivalentFull-time equivalent (FTE) represents a regular building occupant who spends 40 hours per week in the project building. Part-time or overtime occupants have FTE values based on their hours per week divided by 40. Multiple shifts are included or excluded depending on the intent and requirements of the credit. (FTEFull-time equivalent (FTE) represents a regular building occupant who spends 8 hours a day (40 hours a week) in the project building. Part-time or overtime occupants have FTE values based on their hours per day divided by 8 (or hours per week divided by 40). Transient Occupants can be reported as either daily totals or as part of the FTE. Residential occupancy should be estimated based on the number and size of units. Core and Shell projects should refer to the default occupancy table in the Reference Guide appendix. All occupant assumptions must be consistent across all credits in all categories.) occupants, as in LEED 2009, LEED v4 requires one onsite shower with changing facility for the first 100 occupants (a 1% rate), and then another for each additional 150 occupants (a 0.7% rate).
Residential projects must provide short-term bicycle storage for at least 2.5% of all peak visitors, and provide long-term bicycle storage for at least 30% of all regular building occupants. There are also minimums: four short-term spaces, and one long-term space per residential unit.
This contrasts with the LEED 2009 requirement of covered storage for 15% of building occupants.
LEED v4 requirements also address the quality of the bike storage itself.
Bicyclists know that all bike racks are not created equal. Beware of “wheel bender” bike racks and other types of bike racks that neither keep the bike supported nor secure the bike effectively. For LEED, bike racks should "reflect best practices in design and installation," according to the LEED Reference Guide.
That typically means supporting the bicycle in at least two places to keep it from falling over, and allowing the owner to lock both the bicycle frame and one or both wheels with a U-lock. The rack must be securely anchored and resistant to cutting, rusting, bending, and other deformation.
BuildingGreen offers guidance and a curated list of how to find quality bike racks.
Short-term bike storage is for visitors staying for a period of two hours or less. Long-term storage is for more than two hours.
In order to comply with this credit, at least four short-term and four long-term spaces are required. If you are unsure about how many visitors will be expected, a good rule of thumb is to use approximately 10% of the FTE.
To promote bicycling and transportation efficiency and reduce vehicle distance traveled. To improve public health by encouraging utilitarian and recreational physical activity.
Design or locate the project such that a functional entryAn entryway that is designed to be used by pedestrians and is open during regular business hours. This does not include any door that is exclusively designated as an emergency exit, or a garage door that is not designed as an entrance for pedestrians. and/or bicycle storage is within a 200-yard (180-meter) walking distance or bicycling distance of a bicycle network that connects to at least one of the following:
All destinations must be within a 3-mile (4800-meter) bicycling distance of the project boundary.
Planned bicycle trails or lanes may be counted if they are fully funded by the date of the certificate of occupancy and are scheduled for completion within one year of that date.
Provide short-term bicycle storage for at least 2.5% of all peak visitors, but no fewer than four storage spaces per building.
Provide long-term bicycle storage for at least 5% of regular building occupants (excluding patients), but no fewer than four storage spaces per building in addition to the short-term bicycle storage spaces.
Provide at least one on-site shower with changing facility for the first 100 regular building occupants (excluding patients) and one additional shower for every 150 regular building occupants thereafter.
Provide secure, enclosed bicycle storage for at least 30% of regular building occupants (excluding patients), but no less than one storage space per residential unit.
Short-term bicycle storage must be within 100 feet (30 meters) walking distance of any main entrance. Long-term bicycle storage must be within 100 feet (30 meters) walking distance of any functional entry.
Bicycle storage capacity may not be double counted: storage that is fully allocated to the occupants of nonproject facilities cannot also serve project occupants.
