Five Year Solar Performance on Connecticut Home

Written by Gayathri Vijayakumar, VP – Senior Building Systems Engineer

Over the last 10 years, we’ve seen great strides in the solar PV market in the United States. Between the federal tax credit and utility-sponsored incentives, the price to install PV systems came within reach of many homeowners. For others, eager to make a positive impact on the environment, power purchase agreements with solar companies and no up-front costs made it possible to utilize their roofs to generate electricity.

While the calculated cost-effectiveness of solar panels relies on the future price of electricity (which we can’t predict), we can confirm that they do deliver energy. In a very scientific study of exactly one home, owned by a SWA engineer, five years of generation data is available. Sure, it’s not the pretty Tesla roof, but these panels were installed back in November 2011. At 4.14 kW, with no shading and great Southern exposure, the panels were estimated to generate 5,400 kWh/year of electricity in New Haven, Connecticut (Climate Zone 5). The panels have exceeded expectations, generating on average, 6,200 kWh/year, which is roughly 70-80% of the electricity required by the 2,500 ft2 gas-heated home and its 4 occupants.

The Adventures of Mo and Her No Mow Lawn

I always thought the phrase ‘about as interesting as watching grass grow’ conjured a vision of ultimate boredom. That was before I attempted to grow my own no mow lawn. It turns out that watching grass grow can be a roller-coaster of emotions: the angst of wondering whether my inability to precisely follow directions would matter… the excitement of seeing the first blades of green poking up… the anguish over bare spots… and the pride over healthy, lush sections.

April 2015 – The lower tier is seeded; the upper tier wall-building is still in progress

For years I advised clients to consider no mow lawns in their green homes, but I had never seen the end product through a full cycle of seasons. Friends of friends who own a turf farm expressed their interest-slash-skepticism at my undertaking, which more or less echoed the sentiments of a whole stream of landscape architects before. “Sure, you could try no mow if you really WANTED to… ” A search of local nurseries turned up nothing available. I couldn’t figure out why something that sounded so ingenious wasn’t more popular! An internet search for “no mow grass” turns up Prairie Nursery in Westfield, WI as a major supplier. A colleague used their product, and they were extremely helpful on the phone, so I ordered the No Mow Lawn Seed Mix online.

SWA Lifestyles: A Simple Weekend Cabin

By Kai Starn, Sustainability Consultant

Autumn has arrived again in the Northeast and the foliage is in full splendor. Over the Canadian Thanksgiving / Columbus Day weekend, I headed up to Ontario to deliver one final truckload of building materials to my family’s property there, which is located an hour and a half across the Canadian border. While I am a Connecticut native, the land bordering the Frontenac Provincial Park has been in my family for generations. In the 1980’s, my grandfather logged the area, and subsequently built a road and a log cabin on the property, which is where my grandmother now spends time during the summer.

The main cottage is a gathering place for family reunions; as such, I had always envisioned building a small weekend cabin to accommodate extra people for the occasions when there was sure to be a full house. About a year ago, I began to design and build this structure. When completed, the tiny cabin will be a simple, un-insulated cottage of old. But, dang, if it doesn’t scream summer and lake and relaxation!

Energy and Water Use Study in DC Multifamily Buildings

Do you live in DC? Do you own, manage or reside in a multifamily building? If so, we would love to get your feedback!

The District of Columbia’s Department of Energy and Environment (DOEE) has engaged Steven Winter Associates to gain feedback from multifamily owners, managers and residents about their energy and water usage. To start off, we’re conducting brief surveys (10-minutes max), and hope this effort will have positive outcomes for future multifamily projects in DC by raising awareness of green/energy efficiency initiatives.

PURPOSE:
Survey responses will inform the potential development of a voluntary energy and water conservation program tailored exclusively for the multifamily rental sector in the District. This program will include a customized toolkit to engage residents and building managers in improving energy and water efficiency. It will also encourage participation in a peer-to-peer energy and water reduction competition.
