Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com Importance of Net Zero RetroFits In 2011, homes accounted for 22 percent of all energy consumed in the U.S. Slide 8 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com Importance of Production Not Just Reduction In order to solve these problems, the transition to a fully renewable electricity system and a fundamental transformation of the grid will be necessary Distributed generation (DG) like solar photovoltaics will be crucial and will likely need to make up roughly 30 to 40 percent of production by 2050 (up from about 0.2 percent today) Access to renewable electricity supply at home will become increasingly important for the transformation of the transportation system to electric vehicles Slide 9 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com Why is DG Important On Every Single Structure? In order to deal with the intermittency of renewables like solar and wind the electric grid will need to transition to a smart grid infrastructure This will require as wide a geographic distribution of renewable generation as possible to allow supply to be balanced through the distribution grid reducing pressure on the transmission grid Slide 10 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com Part 1: Energy Efficiency and Building Envelopes Slide 11 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com Reduce Before You Produce The first step is evaluate the home & perform an energy audit on: Health & Safety items Comfort issues Energy leakage (blower door test & thermal image scan) Appliances Lighting Heating & cooling Water heating It is always a better value to tighten up the home and to reduce the amount of energy being used prior to getting involved with Renewable Energy projects. Slide 12 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com We create the interest throughout the audit process Customers do not call specifically requesting I want a net zero home, please come & give me an estimate When we receive call for estimates for specific items such as a furnace, geothermal or solar system, we always strongly encourage & recommend an energy audit Home energy performance is the right path for the homeowner and it is our responsibility to embrace this way of thinking full time and always. Not part time when it is convenient. Most All of Our Net Zero Retrofit Jobs Begin with an Energy Audit Slide 13 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com Go together like apple pie, ice cream & caramel syrup! HVAC/Home Energy Performance AND Renewable Energies Slide 14 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com An energy audit is a great way to get this accomplished. When you are seated you can guide the customer through the process. Always reduce before you produce but every now & again you will get a customer who wants to be at net zero. Our net zero retrofit projects usually consists of a) Home Energy Performance b) Geo thermal c) Solar Electric Systems The 1st step is to get a seat at the kitchen table as a consultant. Slide 15 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com We have to deal with many different types of insulation methods to tighten up these older homes. The products we have available are: Open Cell Expandable Foam, Closed Cell Expandable Foam, AirKrete Non- Expandable Injection Foam, and Cellulose These are not one size fits all solutions to tighten up older homes. Home Energy Performance - Insulation Types Slide 16 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com Part 2: Renewable Energy Slide 17 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com We use both direct exchange waterless and water-based geothermal systems to retrofit these existing homes The foot print needed to install a direct exchange system is usually only a 12 circle. We can use a small drill rig on tracks that can get into most spaces. We drill one 4 hole, 100 deep per 12,000 BTUs We can incorporate hydronics and domestic hot water with these systems GeoThermal Slide 18 865 Co. Rd. 6, Phelps, NY 14532 | 800.533.3367 | www.halcoenergy.com We do pole mount systems as well as roof mounted systems and sometimes a combination of both. These systems are expandable so that if a customer wants to start with the home performance piece and then add renewables in the future, it is possible. This is why it is important to establish life long relationships with these valuable customers. Solar PV Slide 19 865 Co.
