Bike Shop A Net-Zero Energy Research Building

Project Type: Research Studio 602: ProfessorArthur McGeoy Location: New Orleans Tools: Revit, Google SketchUp, Sefaira, Climate Consultant Spring 2017: The University of New Mexico

Project Brief Goal Statement: The building should be sustainable. It should produce energy required for its uses. Building should be designed with sloped roofs in order to use solar panels on roofing and curtain wall with glass as major element for natural lighting. The space should be divided into two zones , one for office and service space and the other for display and lobby area.

Project Statement: As per the goal statement, the spaces are divided into two zones. The project comprises of two blocks combined together with sloped roof in order to provide the sufficient shade to the building. 1� insulating glass curtain wall is provided. Walls are of concrete, Aluminum box horizontal Louvres are provided for shading and interior wall is finished with gypsum board. The roof is of concrete supported by Metal deck.

The inhabitant of the project will get enough natural lighting, and sufficient volume with the double height spaces. A lobby is equipped with seating spaces and sufficient area for storage and for Bike service is provided. Display area for repaired bikes is provided at the entrance inorder to provide easier accessibility.

Best environmental strategies to be followed for building design are, A.Use light colored building materials and cool roofs (with high emissivity) and to minimize conducted heat gain.

B.Minimize or eliminate west facing glazing to reduce summer and fall afternoon heat gain.

Daylighting Strategies Considering the climate of New Orleans two daylighting strategies have been adopted to achieve the best daylighting goals.

Building oriented 15 degrees to east-west

A. Building Orientation B.Horizaontal Louvres

4”x2” Horizontal box Louvres

Aluminium box louvres (4”x2”) with spacing 4” are added to the facade glazing facing east and south. The louvres helps to reduce glare or solar heat gain during warm seasons.

The west side of the building is a solid wall with no glazing and opening.

Building Envelope The temperatures in New Orleans range from the mid 40’s in winter to the upper 90’s in the summer.

Rainfall is common in New Orleans, with a monthly average of about five inches of precipitation.

Inorder to maintain maintain the comfort and workability inside the structure, Vapor control layer, Water control layer, Thermal control layer and Air control layer are added to the Building Envelope.

Also steel roof gutters are added to tackle the rainfall effectivly.

0.15 SHGC is maintained for facade glazing system letting in natural light yet keeping the temperatures consistent during winter and summer.
