This project is about the integration of nature with the learning environment in Frick Park on the Beechwood entrance, acting as a transition into the park and the trails. The office and classrooms are located in three solid volumes, while the lobby and greenhouse weave between these components. The openings of the classrooms face the interior greenhouse, allowing plants to seep into the classrooms through the planters that become lab counters for the classroom. These native species are chosen based on height and its ability to enclose space.This project is about the integration of nature with the learning environment in Frick Park on the Beechwood entrance, acting as a transition into the park and the trails.

Terraced Viticulture Hotel

This proposal integrates building systems for humans and grapes, water and wine. Located on a slope in Ithaca, New York, the concept of this terraced viticulture hotel is based on connecting modular units to increase the perimeter of hotel rooms for rainwater treatment. Each hotel unit is designed to address rainwater treatment, thermal comfort, visual and acoustic quality, ventilation and access to nature. Groups of hotel rooms are aggregated according to programmatic and environmental requirements and limitations, creating openings between them to allow light into the deeper interior. The form of the landscape is an extension of the building, creating an optimal drainage pattern for the vineyard.

Environmental Charter School Furniture Design Build

Students are proactive in their own education at the Environmental Charter School. When asked to envision their ideal classroom, the seventh grade class spoke passionately about their dynamic way of learning that required a flexible classroom configuration, their basic needs for storage, as well as their desire to learn in a colorful and comfortable environment. With a budget of $1,000, the team repurposed the students’ desks into colorful padded chairs and storage shelves, and built movable and collaborative white board tables. The project attracted publicity because of the way it empowered the students not only to voice their opinion about what a classroom should be, but also to experience it firsthand.

Waterfront Co-Housing Community

The project began by examining the town of Millvale. The town borders the north edge of the Allegheny river, however, a series of complex highways divide Millvale and the waterfront. While many people enjoy access to the river, it is fairly cut off from Millvale. By building on the waterfront, it encourages a connection from Pittsburgh to Millvale, as well as serves as a public amenity for the town and city. This project seeks to connect Millvale to a larger network of Pittsburgh’s developing riverfront trail system. The site’s location is extremely valuable because it is on the water’s edge, but also has a proximity to widely used bicycle and hiking trails. By trail, downtown Pittsburgh is only four miles away and could potentially be desirable for people who prefer to bike to work in the business district.

While the site is attractive in many ways, it poses challenges. Its proximity to the river is both a desirable trait and a difficulty. In high floods, the entire site would be covered in water, and thus the scheme must address this problem through flood prevention strategies and elevated building design. The site is also on one side of the railroad tracks, which poses an acoustic disturbance potentially two times a day. Currently a series of crosswalks and traffic lights help people cross the tangle of highways. While most of the sequence is complete, a traffic light and some sidewalks are still required to make the waterfront accessible from Millvale.

The public waterfront park will accommodate waterfront activities including boating, kayaking and fishing as well as general outdoor activities such as biking and jogging. Boat, kayak and bike rentals will be provided for the public. The community kitchen will serve a public cafe component. The cohousing project will include barrier free apartments for seniors and the handicapped, small family apartments and large family apartments. Apartments will include small kitchenettes, bathrooms and living areas. The cohousing community will share a laundry room as well as a community kitchen. Lastly, the community’s residents will maintain the waterfront park ‘s landscaping as well as cleanliness as well as take responsibilities for running the cafe and boating and bike rental facilities on site.

Multi-Family Residential Energy Performance Simulation

The building performance analysis is conducted on a 6 story multi-family residential with clubhouse in Pittsburgh, PA. The study aims to investigate different HVAC systems on the building’s energy performance. The investigation includes ontrolling and setting the other variables such as glazing and envelope in attempt to identify the building’s maximum potential for energy performance. Additionally, the study also includes a quick comparison between eQUEST and EnergyPlus, thus identifying potential differences and increase in credibility in the latter simulation tool.

Through careful analytical study of different aspects of the building, the study concludes that the building performance can reach an energy use intensity of 23.81 kBTU/sq. ft./year. As compared to the baseline, the energy performance improved by 35.7%. The study concludes that the building with double guardian glazing with Passivhaus envelope and an VAV HVAC system with heat recovery system was the most effective design solution.

Engaging Stakeholders in Energy and Water Reduction with Data Graphics

Energy disclosure laws have been enacted in major cities in the U.S. requiring various categories of buildings to disclose their utility bills. This not only reveals the potential defects of their energy use pattern but also opportunities for energy saving. However, to effectively convey the findings from the utility data, a report with in-depth analysis and essential information for the viewers is important in order to engage different levels of users to do the right thing---to act on saving energy and water.

How can one transform the endless and unintelligible sheets of data into something meaningful and actionable? How can one provide information to encourage action from different levels of engagement from executives, facility managers, to individuals and the public? What information would the decision makers want to see? What user interface makes the conclusion most expressive to make the readers understand and take action? This research intends to design a compelling report layout with essential information to engage policy makers and facility managers, by analyzing energy use data from different building stacks including 399 Washington government buildings from the Build Smart DC website, 290,676 U.S. Department of Defense buildings, and 3,626 PNC Bank building properties. This synthesis focuses on the engagement of stakeholders on the executive level with the presentation of annual and monthly utility data of a portfolio of buildings.
