Mixed Mode Ventilation with Assisted Buoyancy Flows

This project investigates the potential for a mixed mode ventilation system in the new PDSI building at MIT. It is proposed that the existing atria be unconditioned for much of the year, using motorized louvers and smoke evacuation fans to moderate temperature during certain seasons. The atria would be conditioned in the most extreme seasons. More information is available here.

Spectral, Bi-directional Fenestrations

In this project, I explored the potential for integrating a spectral bi-directional fenestration system in a solar home. The idea is to install a passive window system that rejects near infrared radiation during the summer but transmits it during the winter while at the same time providing visible light for daylighting year round. A presentation on the system is available here

Sustainable, Modular Residences

As part of a class on Open Source Building for Low Energy, Responsive Homes in the MIT Media Lab, I explored ways to integrate renewable energy and water conservation technologies into prefabricated, modular houses. These designs are meant take advantage of prefabricated components that fit into a standardized 12 by 12 by 10 framing system for reduced material consumption and site assembly time. A presentation on my preliminary design concept for a modular, sustianable house is available here.

Solar Decathlon Energy Analysis

The solar decathlon is an international competition among university's to design and build a house powered entirely by solar energy for heating, cooling, ventilation, hot water, appliances, lighting, controls, and any other energy demanding home functions. As part of this competition, I developed a building energy simulation tool that estimates the total annual electricity and hot water production and consumption of our solar decathlon design. The Excel based energy simulation model is available here. An energy analysis of the initial solar decathlon design is available here.

House for an Ecologist

The American Institute of Architects (AIA) hosted a competition to design a "house for an ecologist" that provided a working and living space for a hypothetical ecologist in residence at the National Conservation Training Center (NCTC) in West Virginia. The house was meant to be completely "off the grid", however our design team deliberately worked against this idea. Our team emphasized the designs many connections to social, environmental, industrial, and technological "grids" at many scales, while at the same time producing power, hot water, potable water and replinishing nutrients. Our submission is available here.

UFAD used for Mixed Mode Ventilation

As a final project in the Analysis and Design of Heating, Ventilation and Air Conditioning (HVAC) Systems, each class member designed the basic framework for a new Sloan School of Management building along with a HVAC system for the building. We then analyzed the effectiveness of our design on the summer and winter design days as well as the potential for natural ventilation during moderate seasons of the year. My design attempted to utilize an underfloor distribution system for both mechanical, displacement ventilation and natural ventilation through insulated louvers to the outside. These louvers could be sealed during active conditioning and opened for natural ventilation. A presentation about my project is available here.
