Green Roofs for Healthy Cities

September 1st, 2015

What is a Green Roof?

Green Roof - 7 layers of root barrier - Connaughton ConstructionA “green roof” is an extension of an existing roof on top of the concrete slab, including a high-quality waterproofing membrane, a root repellant system or root barrier, a drainage layer, filter cloth, lightweight growing medium and soil, irrigation system and plants.

How do Green Roofs Make for Healthy Cities?

Green Roofs have Economic Benefits

Green roofs and services create jobs for many people.  According to Green Roofs For Healthy Cities (GRHC)  the demand for green roof installations requires and therefore helps create a business market for manufacturers and suppliers of all the required physical components. That is, all the green roof layers, specialized garden nurseries, architects, landscapers, ecological design and engineering professionals, the labor and maintenance personnel.

Construction costs of green roofs vary from $10.00 to $25.00 per square foot. In Germany where they are more common, the costs of a green roof range from $8.00- $15.00 per square foot. The model green roof at Gund Hall at Harvard University cost $1.00 per square foot.

Green roofs can increase property values.

Green Roofs have Environmental Benefits

Green Roofs have cooling potential. Green roofs provide shade and remove heat from the air through evapotranspiration, reducing temperatures of the roof surface and the surrounding air. They help reduce the heat islands often found in urban areas.

Green roof absorb heat and act as insulators for buildings. This helps us use less energy for cooling and heating.

Green roofs are useful in achieving LEED certification for new and existing buildings.

Green roofs reduce air pollution and greenhouse gas emissions. By lowering air conditioning demand, green roofs decrease air pollution and greenhouse gas emissions. Vegetation remove air pollutants and greenhouse gas emissions through dry deposition and carbon sequestration and storage.

Green roofs improve human health and comfort. Green roofs, by reducing heat transfer through the building roof, can improve indoor comfort and lower heat stress associated with heat waves.

Acoustic insulation properties also exist with green roofs. Many green roofs have been placed near airports with great results in noise reduction.

Green roofs enhance stormwater management and water quality. Green roofs reduce and slow stormwater runoff in the urban environment; they also filter pollutants from rainfall.

Green roofs allow us to grow food locally, eliminating the need to be transported. From herbs such as mint, Lemon balm, edible pansies, thyme, lavender, chives and different kinds of basil are just a few of the many herbs that flourish in the custom-built beds. To vegetables, such as tomatoes, herbs, greens, berries, wheat grass, even some monster cabbage. Restaurants are turning to their own green roof gardens for self-producing fresh herbs and vegetables.

A Net Zero Energy Home costs about 5-6% more when you utilize all the energy incentives that are available today.

Save Millions with Energy Efficient Light Bulbs

June 30th, 2015

The last time I had to buy new light bulbs, I thought I knew what I was doing. Before leaving home, I noted the wattage and the type of light bulb. I get to Home Depot only to find there’s an entire aisle of light bulbs from which to choose. I walk up and down the aisle at least three times. I caved, turned to someone who looked like they worked at Home Depot(wearing the Home Depot apron), “Excuse me sir, can you please help me pick out a light bulb?” Seriously, it was embarrassing.

Choices for Light bulbs

We’ve narrowed it down to the Light Emitting Diode (LED) and Compact Fluorescent Lights (CFL) bulbs and Incandescent light bulbs.

How to buy light bulbs

When buying a light bulb we often buy based on the wattage. But the wattage is actually a measure of electricity, not the brightness of a bulb. The amount of light a bulb generates is measured in lumens.

An incandescent 60-watt bulb, for example, gives off 800 lumens of light. An LED light bulb can deliver the same amount of light using as little as 10 watts. Since an LED draws on less electricity, it is less expensive to run. CFL light bulbs gives off 800 lumens using 15 watts.

You can buy an 8 watt LED light bulb¹ for $4.97. It’ll  use about 329 KWH over the course of one year. You can expect to pay your utility company $32.85. LED light bulbs have a 20 year life span.

An Incandescent light bulb using 60 watts or 3,285 KWH per year with a life span of about 1 year,  and you can expect to pay $328.59 per year.

A CFL light bulb costs about $5.97, delivers 8,000 hours of light, uses 14 watts or 767 KWH per year and you can expect to pay $76.65 per year. CFL light bulbs have an estimated life span of 9 years. Some CFL bulbs can be used with dimmer switches.

Energy Star Light bulbs can save millions

The Environmental Protection Agency says that if every household replaced just one incandescent bulb with an “Energy Star”-rated LED or CFL (compact fluorescent), we would save close to $700 million per year in energy costs.

Is it any wonder we as consumers are confused about which light bulb we should buy? There are so many types of bulbs with different price points and life spans now on the market.

For even more information about light bulbs — the different types available, how long they last and what they cost over the life of the bulb — check out our guide to changing light bulbs¹.
