The Revitalization of Our Communities Through Sustainable Commercial Building Renovation

Share Article

Green & Main has launched a groundbreaking effort in the historic Sherman Hill area of Des Moines, Iowa to renovate a mixed-use building in a sustainable process that will create a roadmap to use on other buildings throughout the state and beyond. The conversion of older buildings in communities across the country will help to decrease our carbon footprint, increase energy efficiency and overall healthiness of our buildings and promote better use of materials.

If we document how effective design-build management decreases the embodied energy of buildings, especially existing buildings, we can limit the use of raw materials, support /regional economies with the purchase of products/materials manufactured within a 500 mile radius and divert demolition and construction waste from the landfill. We can provide a plan that endures.

Green & Main has launched a groundbreaking effort in the historic Sherman Hill area of Des Moines, Iowa to renovate a mixed-use building in a sustainable process that will create a roadmap to use on other buildings throughout the state and beyond. The conversion of older buildings in communities across the country will help to decrease our carbon footprint, increase energy efficiency and overall healthiness of our buildings and promote better use of materials.

The goal of Green & Main is to develop a pilot project that can be replicated and serve as the foundation for applied best practices to provide a plan to help preserve our most precious resource - our communities.

"It is a most critical task and responsibility of developers to aggressively change what we do with thousands of existing buildings," said Chaden Halfhill, managing member of developer Indigo Dawn LLC and President of general contractor Silent Rivers, Inc. "It really is no longer a choice to build sustainably, it is a necessity for our future."

"The ability to renovate downtown buildings and bring them back in line with current energy usage would greatly increase the ability to bring these buildings back into full use while retaining the overall character of the community," states Tracy Lemar, Vice President of Barker Lemar and a member of the Green & Main design team. "Another important aspect of this project is the overall reduction of a building's carbon footprint. As carbon caps and trading become more main stream, this may offer an opportunity to create a viable future revenue stream."

Green & Main will work to obtain Iowa's first Platinum LEED Renovation certification by the U.S. Green Building Council and provide a centrally located building to serve as an exemplary site for design-build best practices in sustainability.

Achieving 75% improvement in energy efficiency over a 'code minimum' standard, producing 15%+ of the building's energy needs with on-site renewable energy, a reduction of 40% in water consumption and regulating storm water up to at least a 5" rain event are several of Green & Main's project main goals.

"Because buildings are responsible for 50% of greenhouse gas generation it is absolutely vital to establish a high-performance model renovation in a standard masonry building that will be regularly monitored and refined for energy efficiency and the reduction of CO2 output," continued Chaden Halfhill, "If we document how effective design-build management decreases the embodied energy of buildings, especially existing buildings, we can limit the use of raw materials, support /regional economies with the purchase of products/materials manufactured within a 500 mile radius and divert demolition and construction waste from the landfill. We can provide a plan that endures."

The Green & Main Applied Best Practices Manual will provide a roadmap for others to renovate existing buildings in a more sustainable way; they will be able to select the level of design, efficiency and certification they want to achieve.

Green & Main will also have an aggressive ongoing education and communications program to track the progress of the project online and in media; onsite events will also be hosted throughout the construction process and after the building is open.
