Bachelor of Sustainable Design
Intro to
Sustainable Design
This course examines the underlying principles of sustainable design within the built environment including resource efficiency, indoor environmental quality, building materials, and land use. By introducing the different strategies and techniques that sustainable designers use to reach these goals, we also work to develop passive and active strategies to be implemented into the project from the very first part of the design process.

Net-Zero Energy Boston
Site Analysis The North End, Boston, MA. A net-zero energy building is defined as a building that generates (on-site) as much energy as it consumes. The development of zero-energy buildings became possible not only thanks to the progress made in new energy and construction technologies, but it was also significantly improved by academic research; which collects precise energy performance data that helps us do advanced computer models that predict the efficacy of the designs. By taking advantage of the site’s attribution, the design concept is molded and shaped based on the initial site analysis for a mixed-use live/work space in the North end neighborhood in Boston.

Design Development Deliverables: Throught the site analysis I performed on Project 2, I designed the initial concept design for a live/work space that adjusts to its environment while at the same time contributing to the area’s social life. The concept design involves building massing and orientation, building envelope strategies, and the selection of renewable systems; based on the idea of sustainable strategies that follow an integrated design approach. This Net-Zero project was made in a conscious approach to energy and ecological conservation in the already built environment, while also taking advantage of the site attributes.

Social and Environmental Interaction This circulation design works by enabling the public to engage with the site directly by connecting the people from the North End to the Boston Harbor through a pedestrian accesible port, this will be a great good contribution to the social atmosphere in the North End by allowing people to interact with the waterfront.
Passive and Active design strategies Passive Strategies: Energy:
-PV System (solar panels)
Heating:
-Trombe wall w/ attached sunspace -Dayilighting massing & orientation
Water Re-use:
-PermeabLe pavement -Water runoff cisterns
Active Strategies: Heating:
-Geothermal system
Water Re-use:
-Grey water treatment system
*Light study
Daylighting and solar passive strategies By taking advantage of the building’s massing, and orienting the design into shapes that work together with the site attributes, and takes advantage of them too; I was able to design a self sustained structure that uses the sun’s direct light to illuminate the inside of the structure through its South facing windows. The program of the building also includes a designated Sunspace which is a very useful passive heating system since it requires little or no effort to operate and they’re ideal spaces where silence and privacy are desired. This space works by facing the room south so it gets maximum sun exposure to help gather the suns heat throughout the day in the thermal mass inside - in this case a concrete floor, walls and roof - and distributing that same heat to warm up other parts of the building. A successful Sunspace optimizes heat gain and minimizes heat loss during cold times, and avoids excess heat gain in hot times as well.

Net-Zero Water Increasing populations will place growing demands on the world’s existing water and wastewater infrastructure. The integration of “closed-loop” systems that emphasize water efficiency, and on-site supply, treatment and reuse is becoming incresingly important as communities seek to strengthen the resiliency of their water systems. By collecting water through the permeable pavement or by catching it from the building’s roof I can redirect it to the cisterns to be re-used in the buildings mixed-use program. By having a building with the combined use of residences, retail and lockerrooms, a good design approach for water efficiency is vital to succesfully cover the water demands. In this case, this project counts with a septic tank that allows us to gather the used water from the building, to pass it through a grey water treatment system that cleanses the water and stores it in the cisterns for later re-use in the facility.
