Project Goal:

43 Neron is nestled among traditional local vernacular homes in the East Carrollton neighborhood. The home is a stylistic hybrid, including neo-classical, local vernacular and modern architectural idioms. The first floor is mostly open, like a traditional Creole cottage with wide porches, both open and screened. All rooms are proportioned using sacred geometries that include classical harmonic relationships within a central cube, which has its primary elevation in the proportion of a golden rectangle. Owner/Architect Steven Bingler designed the home as a laboratory for best practices in environmental and sustainable design for tropical climates, some of which have been practiced for centuries in New Orleans and some of which are relatively new to this region.

Solution:

The LEED for Homes “rating system” provided a menu of sorts for the Architect to explore ideas and possibilities for re-building sustainably. This pilot project features a hybrid passive and active mechanical heating and cooling system. The passive system will operate during hours when the external wet bulb temperature is within the comfort zone. During other times, heating and cooling will be powered by five 300-foot deep earth contact geo-thermal wells tied to a water source heat pump. Other passive systems include: a cross-ventilation system using the centrally located stairway; the stair opening creates a natural cooling “chimney” that channels the flow of air vertically through all three stories of the house to discharge through a louvered attic fan at the peak of the roof.

The primary roof slope is derived from solar inclination and steeply sloped on the west and north encouraging negative pressure across the louver and dormer windows and less steep on the south and east to increase the surface area for rain water collection and to hold more than 700 square feet of photovoltaic and solar hot water panels, which will cover the full triangle of the roof facing south. A 1,200-gallon wooden cistern tied to an integrated rooftop rainwater collection system will provide water for toilets and irrigation. Local HERS Rater Audrey Evans worked with the project team and shared her expertise working on homes in hot-humid climates and verified the installed mechanical systems met performance expectations.
