Introduction The Boston Architectural College, the institutions in the Colleges of the Fenway Consortium Boston University, and Northeastern University have joined together to establish a distance learning mixed-use facility, for use by visiting students and Faculty when their programs bring them to the Boston area. The project will consist of a living and residential part, educational part, and supporting facilities.

Research and Exploration

What are the Environment Goals? In the Owner’s project requirement , it was stated that: first, learning areas should be 100% day lit during the day. Reduce energy consumption by 50% and finally, Have a green area inside the building. To reach both goals of having a building mostly day lit and save the energy. A decision was made to orient the building strictly to the south and maximize the exposure to the south.

Testing and Failures: 1-Triple glazed façade: failed because it will reduce solar heat gain. 2-Rock bed thermal storage: failed because it’s expensive and requires large areas. 3-Trombe walls: failed because they block daylight and views, water filled columns causes glare issues. 4-Stack ventilation: failed because it did not comply with the building’s solar heating and air circulation strategy, instead a cross ventilation strategy was adopted to circulate the air the unconditioned spaces in summer.

Research and Exploration

What is the best way to harvest solar heat? To the left is a comparison between Direct gain, trombe walls and Sun spaces. By the end of this investigation a decision was made to rely on a combination of all, but mostly having a sun space in front of most of the spaces in the building that would serve as a winter garden in cold sunny days and a balcony in summer days bay using movable glass walls. The heat is mainly stored in a concert exposed floor and aesthetic glass columns that are filled with water can be used here and there to provide more comfort. It is known that having a visible heat source will increase physiological comfort levels during cold periods. These columns were not shown in the design, but I would like to add them if I were to work further on my project.

Solar heating: The building is using the difference of sun angles between summer and winter to regulate heat gain by using overhangs. In summer, sun light angles are relatively perpendicular. So, the only heated area is going to be the balconies and the three feet near the window. This were shading was provided by wising automated rolling blinds. In winter, the sun rays will penetrate through the glass walls deep into the building to provide direct gain as well as heating the concrete floor of sun spaces. Day lighting. It is important to note that these sections are showing the widest portion of the building as shown in the plans. So, large projections are affecting one third of the building and having only one projection every two stories allow the sun light to enter deep into one floor every two stories. In order to gain more sunlight light shelves and mirrors are used to reflect a soft light and avoid glare.

Program

The building provides all the amenities a student might require during his study period. Fast food, healthy food, coffee, medicine, nurse room, grocery, day care, worship area. Only worship space was overlooked, yet there are many spaces that are suitable for meditation. To enhance the sense of community. Many gathering spaces, kitchens, performance area are available in all over the building, this is meant to strengthen the ties between students and melt down cultural barriers. Furthermore, having coffee shop that is open to both student and the public is expected to help the students mingle with other people from the city. In the beginning it was intended to create a diversity of accommodation units that fits all students’ needs. This is still valid but more work need to be done on designing flexible built in furniture that can be used in many ways. Like a desk that converts to a bed, A sofa that extends to be a bed. Reinforce learning goals. Having a day lit building and all these green spaces in the building are expected to increase students’ ability to engage in the learning process. Engage the broader learning community. To achieve proximity between Studios and sleeping areas in order to enable students to relax and get some rest during intense study period. This goal was not achieved, instead gathering spaces, multi-use areas were provided in each living floor to enable the students to casually gather and work together.

The building’s exterior

ThermoWood: is produced by heat treating Redwood/Whitewood (Pine/Spruce) to temperatures in excess of 200 degrees Centigrade. During heat treatment, chemical and structural changes occur within the timber which alter and improve some of its basic characteristics. The resulting product is an altogether more durable and stable timber, an ideal material for use in exposed areas such as external wall claddings.

Building’s envelope systems: The southern elevation is mainly treated by using double glazing curtain walls with aluminum mullions. That have operable walls to let in the air from the south east (prevailing wind) to flush out the extra heat in summer. Some areas are treated with ThermoWood rain screen , wooden screen, the solid walls are treated with aluminum metal cladding. The eastern and western façade were made to be completely solid to prevent the unwanted solar heat gain and sun light fro entering the building. If I were to refine this project, I would put more work into the eastern façade, may be a pattern in the material or projected verses recessed units in the building’s skin.

Steel structure with the span of 30’ and the beams depth is 18” in average There are two systems in the building; one is the regular framing which is braced wherever it’s possible. The second system in the sunspace that has a glass roof. The structural system consists of Y shape columns connected with beams and carries the sloped roof of the space.

Across the United States, the average annual energy intensity for office buildings is 79.8 kBtu per square foot and the average cost is $1.65 per square foot. According to the U.S department of energy the average Energy Consumption for a hotel building is (thousand Btu/SF): 110.0 for a hotel. Based on my calculation via Sustainable by design calculator, my building will gain 180 KBtu/SF annually. Of course this heat gain will not be stored or used other than for heating yet, it is expected to reduce the energy required for heating significantly.
