• Cold temperatures require high insulation levels and airtight construction for the building envelope.

• Low sun angles will make solar control more difficult, but direct solar gain can be a benefit if designed as part of a passive solar heating strategy with thermal mass.

• Indirect passive solar heating techniques such as transpired solar collectors can be effective.

• High summer sun angles make solar control relatively easy on the south facade, reducing solar heat gain through windows.

• Low speed winds from the south can be used for natural ventilation.

• Lower night temperatures allow night time purging of heat through natural ventilation. Interior thermal mass can aid night purge effectiveness.

Holistic Sustainable Design

Sustainability is a key design strategy for the Expo Rail Facility by creating a workplace that makes every employee proud to work there and by offering an amenity for the surrounding communities by being a model of environmental responsibility. The Facility will aim to be a minimum of LEED-NC Gold Facility with the possibility of achieving Platinum.

The expansion of the Expo line will create benefits reaching multiple scales including enhancing the experience of the Expo workers and surrounding local community to the Energy and Water savings affecting the larger regional Southern California and beyond.

The facility is being designed with a holistic Sustainable Design approach that considers the Environmental, Economic and Social Priorities – Design for One Earth.

The diagram that appears on all subsequent pages maps the different scales that the EXPO Rail Facility has the potential to impact in a positive way through the sustainability goals set through the Design for One Earth process. The orange boxes explain which scales the sustainability strategies set for each value have the greatest ability to impact.

SUSTAINABILITY

Metro has identified four overarching priorities for the new Expo Rail Facility:

Stormwater Management - to be a zero stormwater runoff facility

Energy Performance - to be a highly energy efficient facility and net-zero energy ready

Community Benefit - to create a community identity and amenity for the surrounding Pico Neighborhood

Employee Benefit - to create the model workplace experience

The diagram (above) prioritizes the Design for One Earth Values for the EXPO Rail Facility. The orange dots that are located closer to the outer dark blue circle represent a stronger emphasis of that particular value for this project.

Pages from Sustainability Report

The building is to endure over time and be able to respond to new needs in the future. Create spaces and systems that are flexible and adaptable. Design the building for a long service life and consider the vast array of changes possible in this century in the technologies serving the building and occupants. Design for passive survivability, which will allow the building to remain fully or partially functional in the event that some adverse condition that may impact power or fuel supplies. Design for community involvement, knowing that connection and preparedness is the key to a community’s resilience and sustainability.

08 RESILIENCE

Resilience Goals:Reduce operational maintenance cost of the Expo Rail Facility by 10%.•Design the building to a minimum 50 year lifespan.•

Scales of ImpactStrategies

Design the building to be valued as an asset by the local community.1. Utilize adaptable and flexible systems and assemblies that can be 2. reconfigured over time.Utilize durable and long service life materials and details.3. Utilize passive strategies such as daylighting, thermal mass and natural 4. ventilation that can provide for visual and thermal comfort without conventional mechanical and electrical systems. Utilize renewable energy that can make the building independent of the 5. electricity grid’s potential interruptions and power losses

The goal for this Affordable LEED home is to provide transpar-ency - transparency of systems, construction, and sustainability that function as an educational tool for the family, for the com-munity, and for McHenry Habitat for Humanity. The home’s shape emulates traditional building types, but as portions are worn away to provide transparency, the form becomes a progressive new building type with echoes of the past.

The 1200 square foot living space provides flexibility of program to accomodate different families. The dressing/closet area is pro-vided for the entire family. This allows for a functional core of the home, centered on the areas that get the most use – bathroom and kitchen. The patio also has 10 foot tall double sliding doors which allow for the living space to open up and flow into the exterior during the milder months.

Barceloneta, historically two-storyfisherman homes situated on a strong grid, were built upon over time creating an overly dense housing community situated next to a very populated public beach. By removing abandoned ground floor structures, openings are created within the existing fabric making new passage ways and giving reference to the experience ofwandering through the old city of Barcelona. The openings function to bring more light and air to the very dense area.

The smaller width of the housing unit is derived from the 8.5 m width of the existing housing and the larger 14 m unit width is derived from the 8.5 m dimension plus the width of the street. The extension of the new units helps create semi-private interior couryard space separate from the public beach front.

The new housing aggregates in-clude spatious one, two, and three bedroom possibilities as well as live-work units on the ground �oor. The units are designed so that the di�erent size units stack on top of one another allowing for greater e�ciency and �ex-ibility in the overall form of the aggregates.

The new housing aggregates al-locates the entire ground level as public space adding an important component to the Barceloneta beachfront. The new pedestrian passageways also inhabit the ground level mimicking the wandering experience of the old city. By stacking the smaller units on top of larger units in the up-per levels, courtyards in the sky create a di�erent kind of public space allowing views into the existing fabric of Barceloneta.
