Our first step in defining what is “green” is to look at the elements that are common across all green activities and programs. The principles shown here all build on the values and benefits that I talked about earlier.Again, green is more than energy efficiency. That’s a good place to start, but what we hope to achieve is something more holistic, that considers not only energy and water, but especially healthy indoor environments, and all the different ways that homes and communities can impact the environment.The principles also include two very important concepts for green activities – that of durability and the related lifecycle approach. Durability involves using materials and methods that will last longer, which produces less waste over time and results in lower replacement costs. Similarly, a lifecycle approach considers what the longer term costs of an activity or product or home are going to be – it considers not just the upfront cost, but all the operating costs, maintenance and replacement costs. Many green decisions make more sense when seen through these lenses.In our program document we’ve outlined how these different principles apply to two different settings – the educational setting, working with residents and homebuyers, and the buildings setting, in construction, rehab, and management.
Green strategies manage the impact of the work we do on the environment, and conserve natural resources, reduce waste, and protect ecosystems. But being “green” isn’t only about that:It’s also about maximizing health and sustainability benefits for the residents and communities that we serve – the social element.The social equity benefits of ensuring that lower income people and communities aren’t left out from benefiting from the latest, healthiest and most affordable technologies.The integrity we gain from walking the walk for ourselves rather than assuming that everyone else should be responsible for dealing with our planet’s challenges.It’s about saving money, attracting money, and surviving in tough economic times – both for residents and for our organizationsAnd, it’s about preparing for a future with scarcer resources – by reducing our dependency on natural resources we can help stabilize costs and uncertainties.And bottom line is – it’s about survival – what are we doing to help keep us all here in the long run? What can we do to make our organizations more economically sustainable in a way that helps make our planet, communities more livable and sustainable places and providing the people we serve with healthier, more comfortable, and affordable homes in the long run.
In homes, the most significant sources of formaldehyde are likely to be pressed wood products made using adhesives that contain urea-formaldehyde (UF) resins. Pressed wood products made for indoor use include: particleboard (used as sub-flooring and shelving and in cabinetry and furniture); hardwood plywood paneling (used for decorative wall covering and used in cabinets and furniture); and medium density fiberboard (used for drawer fronts, cabinets, and furniture tops). Medium density fiberboard contains a higher resin-to-wood ratio than any other UF pressed wood product and is generally recognized as being the highest formaldehyde-emitting pressed wood product.Other pressed wood products, such as softwood plywood and flake or oriented strand board, are produced for exterior construction use and contain the dark, or red/black-colored phenol-formaldehyde (PF) resin. Although formaldehyde is present in both types of resins, pressed woods that contain PF resin generally emit formaldehyde at considerably lower rates than those containing UF resin.
This residence in the North of Broad neighborhood in Columbus, Ohio, was awarded LEED Platinum certification by the U.S. Green Building Council (USGBC) for achievement in green homebuilding. The home is the first Platinum-certified residential dwelling in the state of Ohio and the first in the Midwestern United States. The home was built by NeighborWorks member Columbus Housing Partnership and a collaboration of other non-profits, government, corporate and educational entities. The home: uses up to 60 percent less energy than a traditional house of a similar design; features an Apricus solar thermal system, advanced framing that diminished the amount of wood used for construction a rain garden to keep storm runoff on site and out of the watershed triple pane high performing windows low flow toilets, green cabinetry, and landscaping that includes native drought resistant plants. has two renewable energy systems on the home’s roof, which allows onsite generation of all necessary electricity by using the sun.

What is Green?Healthy and Sustainable Homes Principles
Why are Principles Needed? Energy is most common issue addressed Green building programs are broad and multifaceted, but they don’t work for all projects Nonprofits work in areas outside of building – counseling, lending, community building
Beyond Energy - Water Water supply is limited Less than 1% of world’s water supply is available for human use Water is costly Average household spends over $500/year Using water also uses energy five minutes of water = 60-watt light bulb run for 14 hours Water matters everywhere Southwestern US is highest water use per household (>250/gal/p/day); also highest population growth 36 states facing water shortages by 2013 Source: WaterSense and EPA
Beyond Energy - Health Indoor air matters People spend approximately 90% of their time indoors and 80% of most people’s exposure to pesticides occurs indoors Disparities in health Asthma disproportionately affects children from lower-income families and from specific racial and ethnic minority groups
