The Zero-Net-Energy ROSE Cottage Project Wins the 2013 Marvin Architect's Challenge Showdown

CONCORD, NH--(Marketwired - September 16, 2013) - A new Zero Net Energy (ZNE) home known as the 'ROSE Cottage Project,' which was designed by the Turner Group's David B. Hart, AIA and is featured on the website, has won the 2013 Marvin Architect's Challenge Showdown. The project and architect Dave Hart were declared the winners after 5 rounds of voting and nearly 150,000 votes cast.

The ROSE Cottage Project was completed in 2012 and is located in a rural neighborhood in the capital city of Concord, NH. It contains a total of 3,100SF of interior finished space on two levels. In addition to being a net-zero home, this green building project features multi-generational use and aging-in-place features as part of a sustainable design that incorporates long life cycle values.

More commonly referred to as a "Whole Building Design" approach, the ROSE Construction Method (RCM) is a targeted extension of whole building design with a goal of building projects that produce as much energy as they consume.

Starting with a very tight, well insulated building shell which is constructed with high quality materials that require little or no maintenance, the RCM approach adds readily available solar and geothermal  technologies to drive the energy balance to a zero-net or near-zero-net outcome, all based upon the owner's goals and budget.

Key products used in the project included:

> Bosch Thermotechnology geothermal heat pumps and 9 panel Logasol thermal solar system

BP Solar's 60 panel solar array for on-site electricity production by Talmage Solar Engineering

> NanaWall's sliding/folding door system used to expand the seasonal living space

Marvin Ultimate Clad windows and doors used to daylight spaces while creating a tight building shell

CertainTeed exterior siding, cladding, and roofing products used to construct low maintenance exteriors

Fantech HRV and Premium Bath Fans to provide whole house controlled ventilation w/heat recovery

Glidden Professional Diamond 450 zero VOC interior paint for a healthy, durable finish

Logix Platinum ICF foundation blocks for high performance thermal performance

Stonepeak high-tech porcelain floor and wall tile for high durability and low maintenance

Kinetico Mach water treatment systems which use zero electricity to function year round

Executive Cabinetry zero VOC, Greenguard certified cabinetry for a healthy indoor environment

Phillips LED lighting fixtures for low energy consumption and high quality illumination

> A Solara Awning by Eclipse Technologies used to connect the outdoor living spaces

The ROSE Cottage Project is the first single family home built as part of the new initiative to promote the use of the ROSE Construction Method (RCM) approach through the education of consumers, builders, and developers. Net-zero is also readily attainable on commercial, industrial and institutional projects where the economy of scale helps to decrease the additional cost/sf of the renewable energy features required to balance the energy equation.
