Half Moon Bay Library

Half Moon Bay Library

This new 22,000 square foot library includes separate spaces for literacy services, youth services, a teen room, quiet study space, computer use, a programming space with an attached catering kitchen, a children’s garden, a courtyard and a secondfloor deck. This library replaces an existing 7,285 square foot library that was designed to serve a community of 4,320 – a community which has now grown over six times to over 29,000 people.

The design supports the City of Half Moon Bay’s sustainability goal by reaching a minimum certification of LEED Gold and a stretch goal of LEED Platinum. Integral Group provided energy modeling to estimate the Net Zero Energy potential for the library. Integral also performed full mechanical, plumbing and electrical services, and a photovoltaic system of at least 488 kW will be installed.

The library featured natural daylight and views, healthy indoor air quality, plenty of natural ventilation with mechanical assist, passive cooling, active heating, energy efficient equipment, and active space cooling where required. The design allows for flexibility in schedules, staffing and courses, and will showcase to the staff and community the importance of a responsible design and how this impacts our environment.

The lighting design for the library was developed to compliment the ample daylighting. Visual comfort is achieved through a direct-indirect lighting scheme used throughout with a focus on uplighting the second floor sloped ceiling. The visitor experience is enhanced by the use of lighting to accent architectural features such as the dynamic folding ceiling in the Program Room and circular pendants that echo the curving forms of a cove the in shape of a stream running through the children’s room. On the exterior, bollards keep light levels low and minimize uplight to preserve the night sky in this ocean-side community.
