Bainbridge Architect, Coates Design is devoting this “Architect’s blog” to sharing the design and construction progress of the Ellis Project.
The Ellis Residence is registered with the United States Green Building (USGBC) and designed with the goal of LEED Platinum certification.
Thank you for visiting! Please come back often to observe the progress and of course let us know if you have any questions or comments

These Seattle Architects had the opportunity to climb up on the roof of the Ellis Residence to film the installation of the 20 panel, 4 kw photovoltaic system which will supply about 40% of the power to the residence. The system features 200 watt panels from Sanyo. The panels harness the rays of the sun to create DC electricity which is then inverted to usable AC power. Electricity generated by the panel but not used by at the residence, especially during the summer months, will be sent to the power grid to be used elsewhere. The installation was recently featured on a Bainbridge Island Television broadcast.

Two 4′x8′ solar hot water flat plates have been installed on the lower, south-facing roof of the Ellis Residence. These two panels will collect heat from the rays of the sun to help supplement the domestic hot water supply throughout the year. The Seattle area has some beautiful, sun shiny summer months, and during that time the solar hot water panels will supply all that is needed for the domestic hot water.

Our first look into the Ellis Residence mechanical systems begins with the heat recovery ventilator(HRV). The main function of the HRV is to provide an energy efficient way to bring fresh, filtered air into the house while exhausting stale and contaminated air. The basic premise of a HRV is the following:
1. One set of ducts collects stale moist air from the kitchen and bathrooms. This stale contaminated air passes through the HRV unit and is exhausted to the outside.2. A second set of ducting draws in fresh clean air from outdoors through the HRV unit.
3. As the two air streams pass each other within the heat exchanger core, heat is transferred from the outgoing stale air to the fresh incoming air. There is no mixing of air streams.
4. The HRV unit is able to capture up to 85% of the energy from the outgoing stale air. Filtered, preconditioned fresh air is delivered where you need it – in the living areas of your home.
The Ellis Residence HRV utilizes MERV 13 filters in order to maximize LEED for Homes credits for air filtration.

We are going to start a mini-series dedicated to the various mechanical systems that have been installed in the Ellis Residence. During the next few weeks check in to learn more information about each individual system that has been utilized in a home targeted with the goal of LEED for Homes Platinum. To get you primed, take a look back to the posts on geothermal energy and radiant heating.

We are pleased to announce that the Ellis Residence will be part of the American Solar Energy Society National Solar Tour on October 3, 2009. More details to come. The Solar Tour will mark the third time that the Ellis Residence construction site has been open for public tours since March.

This may not seem like the most interesting topic in the world, but it is one of the more economically accessible energy saving options for a new home builder. The Ellis Residence utilizes a hybrid insulation system. The wall and roof cavities are first filled with three inches of closed-cell spray foam insulation and then finished off with your standard batt insulation. This system allows the house to utilize the greater insulation and air sealing properties of the spray-foam in conjunction with the ease of installation and cost effectiveness of batt insulation. Often insulation is only looked at for its thermal properties (r-value), however, itsability seal around outlets and joints in the exterior sheathing from the outside air temperatures is just as important. As the spray-foam expands it does just that. Spray-foam in the roof cavity also allows us to have an unvented roof assemblywhich if properly detailed and executed will reduce the possibility of condesation and consequent mold growth in the roof cavity.
On average the roofs in the Ellis Residence are insulated to an r-value of 60. In the state of Washington the building code calls for an r-value of 38.
