water efficiency requirements The mechanical system combines energy
sourced from solar-heated hot water, a pellet-fired boiler, and a
propane-fired back-up boiler, to heat a 1,000 gallon hot water sink,
which supplies all of the energy required to heat the house, the
domestic hot water, and the outdoor swimming pool. Above all the owners
plan to share their home as an educational
example of green building.
The Keithan Residence Killingworth CT - Most Intriguing
Residential winner is a classic New England home, in a farm
setting, with today’s modern systems and conveniences, all wrapped up
into a home requiring Zero Energy. The residence is a 3,600 square foot
single family home with a detached garage and barn which is under review
to meet USGBC’s LEED for Homes highest rating of Platinum. The home
displays a maximum number of energy efficient measures to attain the
zero energy status.
The charming home was sited facing south to maximize the solar gain in
the heating season. Trees have been retained on the south and west side
of the house to provide shading in the summer months. The southern
exposure has wide overhangs and sun screens to minimize the heat gain in
the summer as well. The walls have sprayed in foam insulation for
maximum R-value. Utilizing a geothermal well and heat pump as well as an
energy recovery ventilator provides maximum efficiency in heating and
cooling the home. All appliances are Energy Star rated and only energy
efficient lighting was used. Rooftop mounted solar hot water collectors
provide for the hot water needs of the home.
The formerly forested property has been restored and will function as a
small working farm with chickens, vegetable gardens and farm stand,
fruit trees and Christmas trees, all fully organic.
The owner, engineer and architect also wanted this house to be a
learning tool for the trades, community and students.
Royal Bank of Scotland – Most Intriguing
Commercial – This 500,000 square foot office complex in
Stamford is the new US headquarters for RBS Americas and contains the
world’s largest trading floor. According to Chris Riley, Vice President
and Director of Public Affairs at RBS, the bank spared no expense when
it came to greening the building, seeking LEED’s top certification. “It
will be the largest such building in Connecticut, if not all of New
England”. Roger Ferris + Partners incorporated numerous sustainable
features into the building. Sited in close proximity to the Metro North
Railroad station with a narrow and elongated plan configuration that
take advantage of natural day-lighting, the complex boasts an urban
courtyard/rooftop garden with grey-water collection for irrigation of
native adaptive plant species. Operable louvers on the trading floor
adjust automatically to the natural conditions while an interior
daylight dimming system links to all office space lighting.
Commercial Storage Barn - Il Poggio LTD – Most Intriguing Commercial
- The Barn was a delightful effort to make a statement about a storage
barn, it had no pretense to attempt to obtain LEED since there was no
heat involved, but the interior storage of the material handling
equipment, and maintenance work space was lighted by translucent walls
and ceilings allowing natural daylighting during the day and some solar
PV mounted on the roof to generate whatever electrical power was needed
for equipment and lighting at night. The idea was to display outdoor
products on the outside of the building for customers viewing,
illuminated at night by the interior lighting through the panels at
night. A beautifully crafted and unique idea on how to store and
maintain the materials that the company sells.
Connecticut Science Center – Most Intriguing Institutional
- A wonderful LEED Gold certified building that stresses the
importance of sustainable design, with an emphasis on energy savings
throughout the building. Designed by renowned architects Pelli Clarke
Pelli, the building, perched high above the Hartford skyline, captures
the wonder of science as well as the city and state’s commitment to
education and cultural enlightenment.
Kroon Hall – Yale University – Most Intriguing Institutional
- Probably one of the most important buildings constructed in the past
year, in the United States; this is truly a great design and
demonstration of what can be done to provide a sustainable building.
Kroon Hall Yale School of Forestry and Environmental Studies earned a
LEED Platinum certification by the USGBC earning 59 points, or seven
more than required for platinum standing. Kroon Hall was designed to use
81% less water and 58% less energy than a comparable building, and to
generate 25% of its electricity on site from renewable sources. The
building, sited on a previously developed location, displays a white
façade and a partial green roof to combat urban heat island effect.
Its outstanding water efficiency technologies recycles storm water
through a native aquatic plant filtering system. Waste water from sinks
and showers is added to the storm water and for use in toilets and
irrigation. Through onsite renewable energy production and optimized
lighting but primarily for its passive strategies such as utilizing an
east-west building orientation for maximum solar access, highly
efficient insulation, and a natural fresh air ventilation system the
project earned all 13 LEED energy points. Solar energy is generated by a
photovoltaic roof installation and provides 25% of the all electric
building needs. The materials used for Kroon Hall were primarily sourced
within a 500 mile radius and contain recycled content. This building
exemplifies Yale University’s commitment to reduce greenhouse gases and
protect natural ecosystems.
Stoeckel Hall – Yale University – Most Intriguing Institutional
- A wonderful total renovation and extensive exterior terra cotta
restoration of a classic building on the Yale campus, demonstrates the
ability to provide a sustainable environment within an existing
structure and earned the building a LEED Gold certification. The
availability of public transportation as well as water conservation
initiatives in addition to high efficiency lighting, control
ventilations and hot water pump loops, re-using 90% of the walls and
floors and recycling 80 % of the waste materials contributed to earning
the building’s LEED certification. Originally built in 1897, the
building currently houses the School of Music. The restoration included
a 4 story classroom, computer lab and practice room addition.
Rogers International Magnet School – Most Intriguing
Institutional - A splendid teaching environment, the ability to
achieve a sustainable building within the confines of the State of
Connecticut education guidelines is demonstrated to all CT communities
that it can be achieved. Former Stamford Mayor Dan Malloy was quoted as
saying of the project, “The decision to build green is an extension of
the Environmental theme for the curriculum of the school”. The two story
wing of classrooms was designed to maximize daylight , while the media
center, cafeteria, gymnasium and theater are house in a second wing
covered by a planted green roof. An outstanding feature of the school is
a unique rain garden built in the former Clairol headquarters building
foundation which in addition to bio-swales provides onsite storm-water
filtrations. The captured rainwater will provide irrigation for the
extensively planted green roof. Efficient fluorescent lighting augments
daylighting with the use of dimmers. Some of the building’s energy needs
will be met by the photovoltaic solar panels and wind turbine.
Armour Academic Center, Westminster School – Honorable Mention
- A classic example of architecture that is thoughtful and carefully
designed to fit into the campus yet provide the benefits of a
sustainable environment. The 95,000 square foot LEED Gold building
includes a humanities wing and a math and science wing surrounding a
center glass atrium. The center achieved its LEED rating through the use
of a large scale geothermal heat exchange system as well as a high
capacity ventilation system providing fresh air to all classrooms for an
improved learning environment. Highly efficient mechanical systems,
water efficient plumbing fixtures and low emitting paints, finishes and
carpet as well as recycled content building materials all contributed to
the LEED Gold designation.
Chase Tallwood Technical Center, Kingswood Oxford School–
Honorable Mention - Founded in 1909, the Kingswood Oxford
School is located in West Hartford. Key to the sustainability of their
technical building was its siting. Rather than using a more typical
available open space the decision was made to utilize the existing space
between several buildings and not disturb virgin land. The new math and
science building, Chase Tallwood Technical Center, was beautifully
crafted to bridge a series of campus buildings into a functioning unit
that serves the entire school. The use of abundant natural light in the
building’s design and the reconfiguration of an existing energy system
from an adjacent structure as a baseline heat source and then converting
that source to both heating and cooling with a heat exchanger, work to
reduce the usage of electrical power.
