Passive solar orientation (see angles of sun below)
Information provided by Casey Moothart , Owner
The home located at 4415 Haight Avenue in Northside earned LEED Gold certification October 22 ,2015. Located less than a mile from the business district it is within walking distance of public transportation, shops and other conveniences.
This is a modern home design has a number of notable sustainable design features. utilizing corrugated metal fiber cement panels, and cedar on the exterior. Passive solar orientation was implemented in the design of this home. See design above. The walls and roof were constructed of structural insulation panels (SIPs) which make the house extremely well insulated and quiet. It is a very tight construction and meets Passive Home specifications. There is a large south facing white metal roof. It is orientated for future solar panels/home battery installation.
The concrete floor of the home serves as a thermal mass for storing heat. They did not use any XPS rigid foam installation (because of terrible Greenhouse gas potential of the blowing agent used to make it) and instead used EPS. This includes a special high PSI foam board that was placed under the slab of the basement.
An air circulation system (ERV) circulates fresh air throughout the house. This is an ERV (energy recovery ventilation) which works 24/7 to bring a measured amount of fresh air into the house. During the cold months it transfers the heat and moisture from exhaust air to the fresh air for exceptional energy efficiency. It does the same thing in reverse during the warm months of the years.
The exterior design includes No Mow Turf by Prairie Nursery. All the runoff from the yard and downspouts is routed into a retention ponds and then slowly drains to the sewers from there.
Additional green features include:
- Geothermal furnace for both heating and cooling
- the house does not use natural gas at all but has a heat pump, hot water heater and induction cooktop
- has a “smart” hot water recirculation pump
- a combo washer / condensing dryer (LG) that they don’t have to vent out of the house
- insulated inside the basement walls with open cell spray foam
- insulated hot water plumbing lines
- all air sealing was done with tape and gaskets and did not rely on foam or caulk
“Pure” LEED Neighborhood Development

USGBC introduced its pilot LEED Neighborhood Development metrics in 2007. ND became its 5th portfolio standard, joining BD+C, ID+C, O&M, and Homes. Any registered or certified LEED project falls into one of these latter 4 rating systems. ND is a different cut of cloth.
LEED Neighborhood Development is a platform for every type of LEED building as well as non-LEED structure, its concern being sustainable communities, promoting green infrastructure and engaging public spaces as particular hallmarks. This scope of vision, so compelling, largely remains absent ‘in the flesh.’ LEED ND is hardly a blip on the USGBC portfolio screen.
- ND projects, planned or built to date, comprise one-half of 1% of all LEED presence worldwide (391 ND of all 82,954 LEED) as of October 30, 2015.
- Ohio’s ND showing is 2.3% of all ND accomplishment (9 ND of all 391 ND).
- Certified Ohio ND projects originated as ND pilot ventures – a 9 year vintage.
LEED Neighborhood Development got rear-ended by the 2008 national economic implosion. ND tackled highly territorial entitlement agencies. Its scale confronted capital challenges. And, its urban centric preference often made for in-fill limitations at odds with its ambitious scale.
Cincinnati’s Northside Neighborhood turned up the LEED ND dial by its selection as 1 of 6 US communities to experience a ND ‘diagnostic’ by Global Green USA. This program is in its 4th award year through the US EPA’s Building Blocks for Sustainable Communities Program.
Focus of the Work
“Global Green USA was awarded a 5-year grant by the U.S. Environmental Protection Agency (EPA)’s Office of Sustainable Communities under the Building Blocks for Sustainable Communities Program to assist 30 communities across the US with sustainable neighborhood planning. The Sustainable Neighborhood Assessments are conducted using a tool built around the LEED for Neighborhood Development (LEED-ND) standard.“ Source: Global Green USA
Local USGBC salutes Northside achievement, symbolizing too its renaissance by dedicated, talented residential and business energies. Northside bootstrapped its way to its present and that didn’t happen overnight. Local urban core neighborhoods have waxed and waned 20-30+ years. They offer an existing asset base with add-on capability to reach ND certification.
- This long maturation process serves up a built-in critical mass for LEED ND leverage.
- A LEED ND driver, such as Northside’s planned Metro hub, can be ND transformative.
As a first “Sustainable Neighborhood Assessment,” Cincinnati regains LEED ND traction that surfaced with “The Arbors” in Pleasant Ridge, a LEED ND certified plan that got mothballed. How the LEED ND project checklist is now applied is a game changer; it has moved from project specific documentation to neighborhood feasibility analysis. The “pure” ND model could not exist in urban cores simply because urban cores are already established-not newly minted.
