New York City has over 960,000 buildings.
Only 9,000 of them (less than 1%) use the dirtiest heating oil (grades #4 and #6). But those 9,000 buildings are responsible for over 86% of the soot and ozone pollution in the air.
These particulates contribute to the failure of New York City’s air to meet the National Ambient Air Quality Standards and the failing grade received from the American Lung Association’s State of the Air Report not to mention all the unnecessary cases of childhood asthma in New York City’s kids.
What is this dirty heating oil?
Generally speaking, when crude oil comes off the boat into the refinery, the sludgier oil (called residual oil) sinks to the bottom while more refined products, which are less viscous such as propane, gasoline, kerosene etc… (called distillates) rise to the top.
#6 oil is barely refined sludge. It’s the least expensive of the heating oils and has the highest fuel content which starts to explain why people continue to use it.
It is solid at room temperature. This means that the entire oil tank must be kept to at least 90 degrees at all times in order for the oil to burn properly. #2 oil, while more expensive per gallon, burns much cleaner, doesn’t require any additional energy to make the combustion process work properly and typically requires less maintenance than boilers burning #6.
Environmental Defense Fund, with support form the Urban Green Council issued a very informative report called “The Bottom of the Barrel: How the Dirtiest Heating Oil pollutes our Air and harms our Heath” including a great interactive map showing all the buildings currently using #6 and #4 oil.
Before you start yelling at me, let me just say that bio-diesel heating oil substitute is not made from corn. The ethanol that you are thinking of is a gasoline substitute. The bio-diesel fuel I’m talking about is made from used restaurant grease that would have been otherwise dumped into the waste stream.
The major supplier of bio-diesel for heating fuel is Tri-State Biodiesel. If you visit their homepage you can buy fuel or sign up for cooking oil collection – they already collect from over 2,000 NYC restaurants.
Biodiesel can be used alone or mixed in any amount with petroleum diesel fuel. A typical blend of 20% biodiesel with diesel fuel is called “B20,” a 5% blend is called “B5″ and so on.
To incentivize bio-heat, New York State currently offers heating oil customers an income tax credit of 1 cent per gallon of biodiesel used for Bioheat (i.e. 20 cents credit per gallon of B20 Bioheat; 5 cents per gallon of B5 Bioheat). This incentive brings the cost of bio-heat down slightly below the cost of #2 oil. (For a 1-2 family home, the tax credit could be around $300, for a 50,000 SF multi-family building, the tax credit might be in the range of $6,500 depending on the efficiency of the building and the heating system).

Catherine Mohr in her TED talk explains how to get down to brass tacks in deciding how to build your house. The basis of her decisions is how much energy is embodied in the extraction, manufacture, transportation and installation of all the elements that go into a new building.
She’s right but I wish she talked more about reducing energy waste in existing buildings. There are so many strategies that could save so much energy. If we can just eliminate the waste over the next 10 years, then all the cool new renewable technologies that are coming out now can fill in the remaining capacity and then we can finally be on the way to recovery.

Thanks to 3Rblog for this.
If you are like me and can’t remember which plastics go where, Real Simple published an easy-to- read guide about how to recycle everything.
Many of these links are national and concern specific products.
If you live in NYC, check the Don’t Throw It Away page from the Department of Sanitation.
For books, you can trade them through neighborhood book swaps or sell them for (paypal) cash at Powells. If shipping your books across the country doesn’t sit well and you live in Brooklyn, drop them off for (real) cash at PS Bookshop in DUMBO.

I lived in an apartment for 4 years that had mold hiding somewhere. Turns out I’m allergic to mold. I coughed basically the entire time I lived there. It was miserable but I know from where I speak!
When I give a talk about the benefits of good clean indoor air quality, I start by asking the audience who spends an hour a day outside – most of the hands go up. At the question of who spends about 1 to 2 hours outside a day on average, many hands go down and at 3 hours or more, there are rarely more than 1 or 2 hands still raised.
Given that we spend as much time indoors as prisoners typically do, focusing efforts on keeping our indoor environment as clean and healthy as possible is of paramount importance.
#1 Good Ventilation: The most important component of good indoor air is proper ventilation. With all the talk about reducing air infiltration to increase energy efficiency, you don’t always hear the other side of the equation which is to make sure you have adequate fresh air both for healthy breathing and for safe combustion at your boiler. If cooking smells hang around for a while or the rooms smell musty, you might want to check your ventilation rates. Here’s a great explanation of how ventilation rates are calculated. In summer, a vented skylight can take advantage of natural ventilation to flush the house of hot humid air and bring in cool fresh air. Bathroom fans should be run at least 25 mins after showers to reduce interior moisture.
#2 Reduce the Number of Contaminants in the Air that get tracked in on your shoes: 80% of indoor air contaminants can be traced to shoes carrying contaminants from the outdoor world including dog poop, heavy metals from truck exhaust, road kill, garbage truck juice etc….See this post we did about cute mop shoes to wear around the house and 37 reasons to remove your shoes.
#3: Clean the air. Air purifiers work fairly well to remove allergens and contaminants but they create ozone (which is an allergen), and use electricity to do so. A less expensive and more aesthetically appealing way to clean the air is via plant life. This book will show you how to grow your own clean indoor air and this is one of our projects where plants were used to improve the quality of the indoor air. Here’s Treehugger on healing and air-purifying plants in hospitals and the best air-filtering plants according to NASA. If you’re still not convinced, here’s a TED talk with stats and everything about the air purifying powers of plants.
#4: Make sure your smoke alarms are working. Change the batteries annually. By code in NYC, there should be one within 15 feet of each bedroom door (and inside bedrooms in NJ).
#5: Make sure your carbon monoxide (CO) alarms are working. They should be replaced every 5 years or so. CO is lighter than air and is basically undetectable. CO at high concentrations can kill you quickly and at low concentrations can make you feel sick and sluggish. CO is not a naturally occurring compound – it is created from incomplete combustion and should NOT exist at all in your living space. The commercially sold CO alarms typically have a lower sensitivity than a personal CO detector. There should be at least one CO detector within 15 feet of bedroom doors, one near the Boiler Room and anywhere there is a combustion appliance, including in the kitchen. You are allowed to use a combination smoke/CO detectors but we recommend a stand-alone CO detector for the Kitchen because smoke alarms are very sensitive and will drive you crazy if there’s any amount of cooking smoke.
#6: If you smell gas, call the a plumber or the utility immediately.
#7: Open a window (or windows) for at least part of every day.
#8: If you have a leak, correct it immediately! This is a great post describing the importance of managing moisture in buildings. Uncontrolled moisture will destroy your building. And quick!
#9: Use green cleaning products or make your own. Cleaning products with few or no toxic chemicals make your indoor air easier to breathe and keep our waterways healthier. Happy Spring Cleaning!
#10: Remove mold: Mold requires moisture, and a non-ventilated cool area. Repair any active leaks first. Remove mold with (1:5 water:bleach or ammonia/dish detergent). Provide ventilation and heat. Sheetrock is the perfect medium for mold growth, if it comes back after cleaning, you need to replace the material the mold has grown on. Plaster fares much better than sheetrock. Other materials such a densglas can replace sheetrock. Ventilate for fresh air.

We weatherized our house last year. You can read all about it here.
So far, in the 11 months since we completed the work, we have saved approximately $900 on our annual heating bill. Assuming energy prices remain constant (which they won’t – all projections indicate rising energy prices), we will payback the insulation and air sealing portion of the work in about 5 1/2 years giving us about an 18% return on investment. Sure beats our savings account (and our IRA’s for that matter).
I like Suze Orman’s approach in this month’s O Magazine: The sub-heading is “act green before you buy green”
Suze’s top 10 tips (all paraphrasing mine):
- Reduce your energy consumption first before embarking on any energy-saving technology. Start with the small, easy-to-accomplish measures like changing lightbulbs and properly programming your thermostat (if you don’t have a programmable thermostat – get one – it will pay you back in a week!).
- Set an energy-saving goal. Enlist the kids. Offer to give them half of the energy savings if the family meets its goal.
- Pick projects that will increase your property value.
- If using a home equity line of credit for energy-saving upgrades, aim to have it repaid within three years because interest rates are expected to rise (I’d say five years if you can finance high-payback strategies).
- Get a home energy audit from an Energy Star partner (call us!)
- Check DSIRE (Database of State Incentives for Renewables and Efficiency) for all available upgrades. The database is updated monthly. A retrofit project can take some time so make sure you check back at reasonable intervals.
- Talk to your accountant about all eligible tax credits and rebates.
- If you are purchasing new appliances, buy Energy Star.
OK, the next two are mine:
- If you are doing a major retrofit to your house, incorporate an energy audit and energy-saving strategies as part of the construction (we’ll help!)
- Whether you live in a single-family home, co-op or condominium, analyze your energy consumption data at least once a year to see how you are doing.

We have some exciting news!
Ellen Honigstock Architect has teamed up with The Chartier Group to provide energy audits for existing buildings large and small!
Is your building overheated in the winter? Does the air feel too dry? Is there a lot of dust on the surfaces of your living space? These could be signs that your heating system is not operating optimally and your building enclosure is leaky.
An energy audit will identify the causes of these problems and root out wasteful energy use. Once we identify these and other signs of inefficiency, we can then help you implement corrective measures that will make your building more comfortable and efficient and improve your bottom line.
Small measures add up!
Please don’t hesitate to call us to discuss the particular aspects of your building. We will review your building holistically to capture both the easy fixes and long-term intensive measures. Click here to see more information about the services we offer.
We look forward to working with you to make your building as energy efficient and environmentally responsible as it can be!
