Project Summary | Low Energy Home
This new modern home keeps with today's highest
standards for energy performance and home health.
The building envelope includes spray foam insulation
and continuous rigid foam insulation, which combine
for an excellent R-value, dramatically reduced thermal
bridging, and an excellent air infiltration rate
of only 0.65ACH at 50 pascals. Solar electricity
is supplied by a grid tied 2.5 kWsystem on the roof
and uses net metering gain credit with the utility
company. Solar hot water panels are pre-plumbed
for future installation. Heat is supplied by a high
efficiency condensing boiler (95% efficient), with
radiant floors on the first floor, and an air handler
supplying forced hot air to the second floor. A
high-SEER condenser and cooling coils within the
air handler provide air conditioning to both floors
during the summer. A heat recovery ventilator (HRV)
connected into the ductwork provides constant fresh
air while recapturing some of the energy from the
air stream being exhausted. Motion detectors turn
on remote fans in the bathrooms, exhausting unwanted
moisture to the exterior. A portion of the house
has a living green roof, which reduces run-off from
storms and provides aesthetic value. The project
has been registered with the USGBC LEED for Homes
program in an effort to achieve LEED Gold certification
and is Energy Star Certified with a HERS rating
of 39. |

Project Summary | Low Energy Home
The Concord Green House includes great energy performance
and a super healthy home in a very traditional aesthetic
package. The efficiently performing home is well-insulated,
includes great air sealing, and is without thermal
bridging. The house completely wrapped with 2 inches
of rigid and uses expanding spray foam in the wall
and roof framing cavities. The spray foam makes
a huge performance difference, even over a home
with similar R-values as it greatly cuts down on
the amount of unwanted air infiltration (a large
portion of a typical house's heating bill). The
healthy home is maintained with excellent indoor
air quality. The HVAC systems do not include a central
duct system for heating and cooling (a common source
of airborne dust, mold, and other allergens). Rather,
the heating system is hydronic (both radiant floors
and radiators) with a high efficiency condensing
boiler. There is a very small duct system for fresh
air ventilation and air filtration. All of the air
in the house is cycled through a HEPA filter while
a percentage is exhausted and replaced with fresh
outdoor air. The fresh ventilation air and exhaust
air first pass through an HRV to recover most of
the heat in the exhaust air. This filtration/ventilation
combination will maintain the indoor air quality
at the highest of levels. Furthermore, all materials
selected for the house were chosen to be non-toxic,
VOC-free, and formaldehyde-free. |

Project Summary | Low Energy Home
The Masson Residence is a 6,000 square foot luxury
house. The homeowner asked ZED to provide energy
modeling and HVAC design. The homeowner's first
priority was energy efficiency, provided that the
energy efficiency measures were sound financial
investments. Using the predicted energy savings
that were determined by the energy model, along
with the utility costs, inflation rate, personal
discount rate, downpayment percentage, mortgage
interest rate, etc, ZED was able to calculate the
net present value of each energy efficiency measure
and compare one to another. In doing so, ZED was
able to identify the most financially sound measures.
ZED also designed a closed-loop ground-source heat
pump system that provided radiant floor heating
and forced-air cooling. Additionally, a heat recovery
ventilator was incorporated to efficiently maintain
excellent indoor air quality. |

Project Summary | High Performance Homes
Five Lanterns is a luxury housing neighborhood at
The Pinehills in Plymouth, MA. The developer and
builder, The Green Company, asked ZED to provide
energy efficiency recommendations and design the
HVAC systems for the homes. The mechanical design/layout
needed to be adaptable to different customer-selected
building options. Efficient and cost effective selections
were made to both reduce utility bills and gain
efficiencies of scale over numerous buildings. The
'rightsized' systems also reduced the first installation
cost of the system as well as the ongoing operating
costs. Cooperative efforts led to one of the best
Energy Star ratings yet achieved by the builder.
ZED also led a seminar for the Green Company's sales
team that served as a primer to green building,
energy efficiency, and where the Five Lanterns homes
fell in the spectrum. Selected by Boston magazine
as the Design Home 2008, the homes also received
5 national design awards including Best in North
Atlantic Region award from the 2008 Best in American
Living Awards. |

Project Summary | Commercial Deep Energy Retrofit
The Center is the heart of this dynamic property,
which includes numerous agricultural and commercial
structures on well over 1,000 acres. For over 200
years the original farmhouse has been home to generations
of the Appleton family. This commercial rehabilitation
project will focus on conversion of 4,700 square
feet of the house including two distinct elements,
the original 1794 farmhouse and the 1872 west wing,
both of which have been abandoned and “mothballed”
for over 15 years. This LEED-registered project
is undergoing a deep energy retrofit, including
a full gut to the frame, fully updated building
envelope, complete systems replacement, and the
addition of renewable energy systems. Targeted energy
performance is well beyond a 50% reduction when
compared to Massachusetts Building Code requirements.
Planned tactics include: super-insulation (rigid
insulation board and closed cell spray foam), high-performance
historical windows, high-efficiency wood- or pellet-fired
boiler, heat recovery ventilator coupled with ground-loop
heat exchanger, air-source heat pumps, solar thermal
hot water systems, automatic lighting controls,
and smart thermostats. |

Project Summary | Low Energy Home
The 100k House is an affordable housing project
in Philadelphia, PA. The developer's concept was
to build urban-infill, two-bedroom homes targeting
LEED Platinum certification with only a $100,000
construction budget. With cost effectiveness being
paramount for the project, ZED developed energy
efficiency recommendations that reduced the home's
energy use by 44%. An optional package with a slightly
higher construction cost produced higher performance
and included a solar thermal system. |

Project Summary | Passive House
The Landau Residence is a 3 bedroom house that is
being designed to meet the rigorous Passive House
standard. The house will be air-tight and super-insulated,
with R-60 above-grade walls, R-80 roof, R-40 basement
walls, and an R-70 basement slab. The windows will
be custom made with low U-values (very insulative)
and high solar heat gain coefficients (good for
passive heating). The heating will be provided by
an active solar thermal-fired hydronic system. Solar
themal panels will provide the hot water and small
circulators will distribute the hot water to low-temperature
baseboard radiators throughout the house. A heat
recovery ventilator will be used to ventilate the
house in an energy efficient manner. A small photovoltaic
system will be installed to offset 100% of the energy
consumed on site. |

Project Summary | Passive House
This private retirement residence located in a oceanside
community features high performance in a small package.
The owners desired exceptional performance with
a modern aesthetic, combined in a house no larger
than their needs. The answer is a simple gable roofed
structure, designed to meet Passive House criteria,
and rightsized for the couple's lifestyle. The high
R-values, R-40 walls, R-40 slab, and R-70, roof,
means that only 6,600 btu/hr is needed for heating
on the coldest day. This is a fraction of what a
conventional house would require. In addition to
the very small heating system, the house will also
incorporate a heat recovery ventilator to maintain
excellent indoor air quality and do so at a minimal
energy expense. |
