In celebration of Earth Day.
Did you know there is a tree planing program in Albany ran through DGS?

To encourage planting trees, the City will underwrite one half of the cost of purchasing and planting a tree. The trees are to be planted in the city right of way in front of or on the side of your home. Trees are available to be planted for the spring and the fall planting, while supplies last. To receive an order form, call the Department of General Services at 434-2489.

Here are 10 benefits that should encourage you to plant a tree.

1.

Trees combat the greenhouse effect

Global warming is the result of excess greenhouse gases, created by burning fossil fuels and destroying tropical rainforests. Heat from the sun, reflected back from the earth, is trapped in this thickening layer of gases, causing global temperatures to rise. Carbon dioxide (CO2) is a major greenhouse gas. Trees absorb CO2, removing and storing the carbon while releasing the oxygen back into the air. In one year, an acre of mature trees absorbs the amount of CO2 produced when you drive your car 26,000 miles

2.

Trees clean the air

Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark.

3.

Trees provide oxygen

In one year an acre of mature trees can provide enough oxygen for 18 people.

4.

Trees cool the streets and the city

Average temperatures in Los Angeles have risen 6°F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased.

Trees cool the city by up to 10°F, by shading our homes and streets, breaking up urban “heat islands” and releasing water vapor into the air through their leaves.

5.

Trees conserve energy

Three trees placed strategically around a single-family home can cut summer air conditioning needs by up to 50 percent. By reducing the energy demand for cooling our houses, we reduce carbon dioxide and other pollution emissions from power plants.

6.

Trees save water

Shade from trees slows water evaporation from thirsty lawns. Most newly planted trees need only fifteen gallons of water a week. As trees transpire, they increase atmospheric moisture.

7.

Trees help prevent water pollution

Trees reduce runoff by breaking rainfall thus allowing the water to flow down the trunk and into the earth below the tree. This prevents storm water from carrying pollutants to the ocean. When mulched, trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.

8.

Trees increase property values

The beauty of a well-planted property and its surrounding street and neighborhood can raise property values by as much as 15 percent.

9.

Trees help prevent soil erosion

On hillsides or stream slopes, trees slow runoff and hold soil in place.

10.

Trees provide food

An apple tree can yield up to 15-20 bushels of fruit per year and can be planted on the tiniest urban lot. Aside from fruit for humans, trees provide food for birds and wildlife.

Summer approaches: Think Cool Roofs

“To combat climate change, there’s no question that we need to increase the earth’s albedo,” or reflectivity, Dr. Gaffin said. “Some scientists are contemplating tinkering with the earth’s atmosphere to do this, but we should start with what’s easy and uncontroversial — white roofs.

Before you proceed with this article. One caution is to mind your surroundings.  Cool roofs must be considered in the context of their surroundings. It is relatively easy to specify a cool roof and predict energy savings, but some thinking ahead can prevent other headaches. Ask this question before installing a cool roof:

  1. Where will the reflected sunlight go? A bright roof could reflect into the higher windows of taller neighboring buildings. In sunny conditions, this could cause uncomfortable glare and unwanted heat for you or your neighbors. In these cases, building owners can opt for a cool colored roof to provide some improvement in reflectance without significantly affecting neighboring buildings

Here is a video that captures a case study in NYC. I was particularly interested in the fact that it is a material that is mindful of its historic context, community, and is able to conserve the environment.

Traditional roofs are dark and retain the sun’s rays as heat. During the summer, heat absorption increases roof temperatures, air conditioning costs, energy demand and even local temperatures in a phenomenon called the Urban Heat Island Effect. Cool Roofs can reverse these impacts!  According to the NY Times article White Trumps Black in Urban Cool Contest

Here are some interesting diagrams from that outlines the impacts of when the sun hits a black roof versus a white roof from
Cool Roof Tool Kit.  As you can see you can see there are several environmental implications at hand.

Cool Roofs Lower Cooling Costs
A conventional roof can reach very high temperatures on a sunny, windless day. A Cool Roof creates a cooler building envelope, reducing the cost to cool the building in the summer.

Cool Roofs Offset the Urban Heat Island Effect
The Urban Heat Island Effect is a phenomenon in which the high concentration of dark material, such as asphalt and conventional rooftops, increases the temperature of densely built cities by up to five degrees. Cool Roofs mitigate this effect by reducing the number of dark energy absorbing surfaces.

Additional benefits

  • Cool Roofs prolong the life expectancy of the building cooling equipment, which doesn’t need to work as hard or as long to cool the building.
  • Cool Roofs reduce the electrical power of HVAC equipment which can run less frequently and with lower capacity.
  • Cool Roofs lower air pollution and greenhouse gas emissions by reducing power demand.

How a Cool Roof Works

A Cool Roof is more than just a roof painted white. To be a Cool Roof, a roof must be treated with a specialized coating material that is lightly colored and has two unique properties: high solar reflectivity and high infrared emissivity.

Solar reflectivity expresses the degree to which a roof reflects the visible, infrared and ultraviolet rays that comprise solar energy. Surfaces with high solar reflectivity reflect more infrared and ultraviolet rays.

Infrared emissivity refers to the roof’s ability to give off its absorbed heat. Highly emissive surfaces are cooler than non-emissive surfaces since they have the ability to shed more absorbed heat at a faster rate.

A Cool Roof reduces the amount of energy absorbed by the roof which helps lower a building’s temperature and cuts energy costs.

Optomizing energy for historic homes

EHS

Are you wondering how to lower your energy bills without losing features that give your house its character? Are you concerned about how your decisions might affect the long-term maintenance or condition of your home?

Historic homes were constructed using different techniques and materials than most modern structures. They were typically built with environmentally friendly features such as:

  • Thick walls
  • Light-reflecting finishes
  • Operable windows and shutters
  • Vents
  • Awnings and porches to provide shade
  • Locally sourced materials

Older homes can be made more energy efficient. They simply need to be treated with a thoughtful, whole-house approach.

Maximize Your Home’s Original Energy Saving Features

Here in Albany, NY,  some of these considerations may be applicable to your individual needs:

  • In the northeast, saltbox-style houses were positioned so that the long slope of the roof directed the cold north wind up and over the house to keep the house warmer in winter.
  • House and buildings were grouped in an L or U-shape to create a sheltered dooryard in which to work.
  • In areas where the winters are cold, chimneys typically run through the center of the house to allow the heat to radiate into the rooms.
  • Thick masonry or adobe walls work in both warm and cooler climates. The walls provide thermal mass to absorb the sun’s energy during the day and transfer it very slowly to the interior. This helps keep the interior cool during the day and warmer in the evening as the heat works its way through the walls.

Owners of older and historic homes can continue to use these practical features as they were originally intended, or rediscover them, making use of their great energy-saving potential.

How can I establish a baseline comparison of where to start with my historic home?

Energy audits provide the best way to identify air leaks in your home. This comprehensive audit will create a roadmap of where and how to best make improvements on your home. This is especially critical with historic homes because air sealing can dramatically alter how moisture moves through the structure.

Here is a  video from NYSERDA that outlines the steps involved in assessing where the common inefficiencies are in buildings. (While the property they are looking at is in not historic, you can at least get an idea of the process)

Be sure to check out NYSERDA’s website that focuses on the Residential Opportunities.They also have their 2013 issues available on line to download

The diagram at the top of the page was found on the Edinburgh World Heritage Site. I liked it because it referenced what they call “Behavior Change” which essentially is the reduction for the need of energy.

Historic Wooden Windows

window imagaes

There are many resources out there that can explain the  facts and myths of the replace vs. restore historic windows debate. Despite the bad rap windows account for only 10-15% of energy lost through mostly air filtration. One thing to do is to make sure your windows fit tightly by repairing them and adding weather-stripping, interior or exterior storms and interior window treatments.

According to the Weatherization Tool Kit by the Division for Historic Preservation, they suggest avoiding replacing historic windows with new windows. You may find asking yourself why bother because of all the extra time and effort it takes.
But here are some reasons that will encourage you to restore your historic windows:

  1. Replacement windows are often more expensive, they have a limited life span.
  2. Replacement windows can change the character of your historic home.

If you live in a Historic District in Albany you should check with the Historic Resources Commission (HRC) to follow their suggested protocol. It is important to be aware of what we talked about way back in the first post. Check with your local agencies!

Here is a diagram of common windows to historic buildings found through NY State:

Image

The key component is to think about each individual window. Creating a survey system of each window and door will be really helpful. Simply rate the windows (poor, fair, good, excellent) Once you have a survey of each window you can account for the individual circumstances of each one.

Common Problems with historic windows:

  • Sticky Windows/ Loose Windows
  • Replacing Glazing and Putty
  • Sash Cords and Weights
  • Cracked Paint: If your house was built prior to 1978, trim and window elements likely contain lead. See Environment Protection Agency for regulation

Here is a diagram from the Division for Historic Preservation NY State Office of Parks, Recreation and Historic Preservation of where the air infiltration occurs most often:

Image

A. Weather-stripping should be installed at the jambs, the sill, the head and the meeting rails. Use a thin putty knife to slip behind the stop and lightly pry off. This will allow you to remove the sash and install spring bronze.
B. Spring bronze is a good choice for the jambs. The strip is nailed to the jamb channel along the interior side of the stop or parting bead.
C. An interlocking strip is best for the meeting rails. When the window is closed, the strips close off any air gaps. The sash lock pulls the meeting rails tight.

Here is six minute video from Mac Bagala called Window Restoration 101. The video outlines the process involved in restoring a historic window. He has even included a soundtrack for your enjoyment. I really enjoyed seeing the entire process and while we often just want to get our windows un-stuck and opened, I can now see the patience and craftsmanship involved in restoring old wooden windows.

In addition, John Leake a Maine preservationist has a great resource on the web as well as a book called Save America’s Windows that is a very useful guide.

Vunlerable exterior parts of a historic home

Image

The exterior diagram outlines the vulnerable elements of your home that are most susceptible to deterioration and drainage.  Before undertaking any kind of maintenance, repair or improvement, you should keep a record of the existing condition of your house. Typically you should check it every fall and spring to prevent small problems from worsening. Regular and through inspections are required to maintain a historic home.

Here is a typical Time Inspection Timetable that may be helpful to understand the frequencies of the inspections.

Image

Developing a Maintenance Plan

  • Assess the condition of your property using an inspection checklist
  • Determine how often you will inspect each element
  • Identify which items you can appropriately inspect yourself
  • Identify those items for which you may need a professional to inspect the property
  • Maintain a list of qualified professionals, contractors, and tradesmen that may be contacted for advice, recommendations, or repairs.
  • Develop a timetable for maintaining, improving, and repairing items that need attention.

Funding Resources

TAX CREDITS

While it isn’t up-front cold hard cash. There is a fantastic program dedicated to historic properties in NY State.  There are two to receive tax credits if you qualify. This is orchestrated through New York State Office of Parks, Recreation & Historic Preservation.

Keep in mind you can look on New York State Department of Taxation and Finance for information as well. (click on the underlined portion)

1. New York State Historic Home ownership Rehabilitation Tax Credit Rehabilitation 

Rehabilitation work on historic residential structures may qualify for a tax incentive. The credit will cover 20% of qualified rehabilitation costs of structures, up to a credit value of $50,000.00. Houses must be an owner-occupied residential structure and be individually listed on the State or National Register of Historic Places, or a contributing building in a historic district that is listed on the state or National Register of Historic Places. In addition, the house needs to be located in an eligible census tract. At least $5,000.00 must be expended on qualifying work. At least 5% of the total project must be spent on the exterior of the building. All work must be approved by OPRHP prior to start of construction.

2. New York State Tax Credit Program for Income Producing Properties

This tax credit must be used with the Federal Investment Tax Credit Program for Income Producing Properties. Owners of income producing properties that have been approved to receive the 20% federal rehabilitation tax credit automatically qualify for the additional state tax credit if the property is located in an eligible census tract. Owners can receive an additional 20% of the qualified rehabilitation expenditures up to $5,000,000 *. In order to qualify, the placed-in-service date must be after January 1, 2010.  After Part 1 and Part 2 of the federal application are approved by the National Park Service, The New York State Office of Parks, Recreation, and Historic Preservation will issue a certification form allowing owners to take the state credit.

Be sure to look at SHPO’s website for further clarification and we’d be happy to help in any way possible.

Here is a map that outlines the qualifying districts in Albany county. Please keep in mind that you have to own a property that is on the National Registry and be in a qualifying district. If you have any questions please contact SHPO for further information.

Are you in a Historic District?

Congratulations! You now have a historic home in Albany, NY that is in a historic district. If you are in question about your district, please refer to the Historic District Map from the Historic Resources Commissions website.

What does that mean and how will that impact you?

The best case scenario is that your home is in perfect condition and the previous owner has updated everything beautifully and you are in the clear. That is wishful thinking. There is always a window that may need replacing or exterior painting that needs updating. The main thing to think about as you begin to look closely at the challenges ahead on fixing  your property is that you will have play by the rules. By this point, you have already acknowledged the property’s importance to its community, state and some people will argue to the NATION. However the initial impact for you can seem costly and time-consuming, but there are resources that can help you through the process. This goes without stating, Historic Albany Foundation can always guide you through these steps.

There are a few resources affiliated with the City of Albany to know about as you move forward
