Concentration of CO2 in the Atmosphere

NESEA Speakers at BuildingEnergy 15: Marc Rosenbaum

Tuesday Workshop – Marc’s Zero Net Energy Deep Energy Retrofit

Tuesday, March 03, 2015
10:00 am to 1:00 pm
BuildingEnergy 15 Workshops

A building energy geek gut-renovated a small house. Learn about the decisions made, and consequences thereof; about choices of construction assemblies, materials, windows and doors, and mechanical equipment. Successive blower door test data will illustrate how the building was tightened to exceed the Passive House standard. Detailed energy use data will be presented, and performance data of the solar electric system, heat pump, heat recovery ventilator, and heat pump water heater will be presented, and will be compared to the energy model. Lessons learned, opinions, and some less-than-obvious observations about various aspects of the project will be shared. As always, both mistakes and successes will be cheerfully presented, and there will be plenty of time for discussion.

Minisplit Heat Pumps: Lessons from the Field

Thursday, March 05, 2015
2:00 pm to 3:30 pm
Single Family

Minisplit heat pumps are now used in most high performance homes in New England. Kohta monitored eight homes built by Transformations and Marc has over sixty homes and non-residential buildings with minisplits. After a brief overview of system types, we’ll share energy use data as well as comfort and distribution studies, and cover issues with installation, sizing, setbacks, and some of the quirks of this nifty technology. Have fun with two MIT nerds!
