North End Portsmouth will offer the convenience of a downtown grocer through Whole Foods Market. Through environmental stewardship, Whole Foods Market will deliver many local benefits including a local producer loan program, community giving and many other unique programs.
The Proposed Mixed-Use Development in Portsmouth, NH will pursue LEED for New Construction 2009 certification. The project team would like to attempt the certification at gold level. The strategies and assumptions presented in the attached project scorecard will allow the project to attempt 60+ points, as required for the gold level.
LEED-NC 2009 certification is divided into 5 major categories: Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources and Indoor Environmental Quality. There are 2 supplementary categories: Innovation in Design as well as Regional Priority.
The project undertook an effort to carefully analyze the proposed site to avoid unexpected contaminants – the Phase 1 ESA determined that no contamination was present. If any contamination is found during construction, the site will be cleaned up as required by regulations. The site location limits the amount of public transportation available however the project is located in a close proximity to two bus stops, serving 2 lines. The project is located adjacent to multifamily residential neighborhoods and provides walking access to numerous basic services.
The site design will try to maximize the open space and vegetated areas in order to improve the pedestrian and occupant experience as well as restore the natural habitat, currently not present at the site. Proposed strategies include stormwater runoff reduction, heat island effect prevention as well as avoidance of light pollution.
The project will also maximize alternative transport opportunities within the site, by providing preferred parking for low emitting vehicles as well as electric vehicle charging stations. Bicycle racks will be provided for the occupants and the public, while the employee changing facilities will include showers. The project will promote walking by enhancing the pedestrian experience around the site – the sidewalks will be improved, new trees and planters will be provided, Wholefoods will feature an outdoor café.
The designed vegetation will complement the existing one surrounding the site, the selected species will be native or adapted, low maintenance and draught tolerant. This will minimize the need to use harmful chemicals, expenses associated with maintenance as well as unnecessary potable water use for irrigation purposes. The project does not intend to install permanent irrigation system. Any water needed for plant irrigation would come from the collected rain water.
Indoor plumbing fixtures will be low flow, including ultra-low flow faucets, low flow showers, low flow kitchen sinks, pint urinals, dual flush toilets and low flow single flush toilets, depending on the location. The occupants and public will be educated about the reduced water use practices through signage.
Energy and atmosphere
The building intends to reduce energy usage and associated carbon emissions through architectural and systems design. The compact structure is being optimally sited to take advantage of passive design opportunities. It will include advanced building envelope, highly efficient mechanical systems, daylight harvesting opportunities, significantly reduced lighting power density and lighting controls.
The project team is considering incorporating tools that can be used by the building operations team for analyzing and optimizing ongoing energy usage. The integrative design process implemented by the project team will maximize opportunities and synergies between building elements as well as allow for optimizing design and provide operational savings.
The building will be fully commissioned and it plans to purchase renewable energy credits to offset its energy usage by renewable sources.
Materials and resources
The project will be designed and constructed to minimize its impact on the environment. The construction waste will be diverted from landfill. Selected building materials will come from renewable sources, will be regionally sourced to promote local economy and limit CO2 emissions associated with transport, will contain recycled components. The project team will prepare recommendations for recycling opportunities during operational phase.
Indoor Environmental Quality
The main goal of the project team is to design and construct a healthy and comfortable building which will maximize wellbeing of the occupants.
All building materials and products will be low emitting and tested in accordance with the LEED recommended standards. Lighting and HVAC will be optimized to enhance the occupant comfort. Spaces will be well ventilated, daylit, will feature operable windows where feasible and occupants will be provided with views of the surrounding nature. Implemented construction practices will improve indoor air quality.
Innovation in Design
The project will utilize a number of innovative solutions including low mercury lighting, educational displays and signage, green cleaning, design for health, and others. The team will also propose strategies to be implemented in the operations phase that will increase sustainability of the project, like green cleaning, green building tours or organic landscaping.
