How Much and How Much Better? A Case Study of Zero-Net Energy Housing in Northern Minnesota

Abstract

Greenhouse gas emissions, the most prevalent being CO2, methane, and nitrous oxide are collecting in the atmosphere and impacting all organisms that reside on this planet. We have the resources, knowledge, and technology to reduce these emissions, thereby slowing, stopping, and even reversing the negative impacts if we move quickly and make the big investments needed to make a difference. Each sector can make significant contributions to reducing emissions and this paper models the energy, financial, and CO2 savings of a net-zero residential home design in a very cold climate (northern Minnesota, USA) compared with the same design built to current Minnesota Residential Energy Code minimums. Results of the modeling and next steps are discussed.
