LG 360 Q1C-A5 An estimated annual energy consumption of 8505 kwh suggests that a solar array of at least 7.2 Kw must be installed. To foster energy consumption awareness and efficient use of electricity in the home, a home energy monitor is to be installed. NET ZERO OPTION

While pv panels are up to 96% recycleable, the process is labor- and time-intensive. Reusing this system offers both energy and economic sustainability options by diverting material from landfill as well as financial payback.

PASSIVE LIGHTING The RE_CON 01 housing program prioritizes passive lighting techniques to create a comfortable and healthy environment throughout the home. The target buyer may utilize the home as a live work space. In this case, they will likely spend the majority of daylight hours within the home. RE_CON 01 addresses this scenario by capturing both direct and ambient sunlight, seeking to brighten the livingspace. As this can be difficult in an urban infill project, the eastern facing double height space and wester facade are designed to bring in as much light as possible. As the sun moves throughout the day, the strategically placed transom windows on the southern facade allow ambient light to enter, while maintaining privacy between the occupant and neighbors. As in many passive homes around the world, the solar heat gain coefficient of all windows must be balanced with both the visible light transmission as well as the heating and cooling loads of the home. 19.5 MMBTU/yr LIGHTING & APPLIANCE LOADS Plug Loads 16.4% Washer / Dryer 17.2% Mechanical Ventilation 7.1% Dishwasher 4.7% Interior Lighting 24.3% Refrigerator 11.1% Oven / Range 19.2%

The RE_CON 01 housing program’s MEP systems are not often seen in the current Pittsburgh housing market. As a result, prospective buyers of RE_CON 01 will need a user friendly access point from which to manage the home’s systems to fine tune the home to their comfort and energy preferences. A home energy monitoring system affords occupants the ability to not only learn about the advanced systems keeping the home comfortable, but also to monitor the energy consumption and financial impacts that follow. The Sense Home Monitoring System is connected directly to the home’s electrical panel in order to monitor solar production and power consumption in real time. With user-friendly feedback through the Sense app, prospective buyers of RE_CON 01 will be able to adjust their usage of conditioning systems, appliances, and lighting based in order to maximize energy savings.

RE_CON 01 will utilize a ground-source geothermal heat pump to power both heating and cooling the interior spaces. A built-in heat exchanger powers the hydronic sub-floor radiant system during heating season, while a blower directs chilled air through a ducted system during cooling months. The ducted cooling system and heat pump electric water heaters tie into RE_CON 01’s energy recovery ventilator.
