This document is for a watt diet study of a 999 sq ft ADU in Palo Alto. The main house has a 200-amp existing service panel. Planners were asking for an upgrade to 400-amp main-service based on the original load calculations. We were able to show that an upgrade could be avoided.
This document discusses the full electrification of residential buildings in Alberta, covering aspects such as the Watt Diet, appliance swapping, load-sharing devices, and a few examples of piloted devices and applications. Single-line diagrams are provided for reference.
This letter to the CPUC for the Net Energy Metering 3.0 proceeding of December, 2022, includes a comprehensive literature review of Time of Use rate research that illustrates no TOU study, hypothetical or real-world, to date has shown Low Income households to benefit from TOU rates.
The primary objective for the project team is to analyze cooking session data taken from the Atascadero housing complex and determine if an 1800W induction cooktop is sufficient for their cooking needs. The project deliverables summarized below reflect the data analysis requests of the client (Redwood Energy) and are within scope of what is extractable from the data set provided.
Redwood Energy was contracted by Trinity Church in Menlo Park to deliver a feasibility report and plan for reducing natural gas use on its campus and adding a resilient microgrid so that the campus could be used as a shelter during grid outages. This document includes budget estimates for needed equipment and specific equipment recommendations to replace each gas appliance.
Comparing Utility Rates and Additional Solar Needed to Offset Costs of 2019 CA Title 24 Prescriptive and High-Performance Apartments in All-Electric vs. Natural Gas-Hybrid Scenarios
For new homes, an all-electric home is much more economical than adopting a dual-fuel home with two space conditioning appliances. In addition, taking into account the avoided cost of an NG infrastructure cost, the economics of an all-electric home gets even better. For existing homes, the current capital costs of HPSC are only around 10-15% higher than air-conditioners (AC). So already replacing retiring NG furnace or AC with an HPSC makes economic sense. Mandating new homes to be all-electric and incentivizing homes with AC and NG furnace to switch to HPSC will help bring down the installation cost of HPSC, due to economies of scale. Greater customer adoption will require larger outreach and education to consumers, building contractors, plumbers and technicians and developing regional partnerships that set market adoption targets, standards-setting, or performance goals in heat pumps.
Redwood Energy has led the design of more than 20,000 units of Zero Net Energy, all-electric affordable housing, and 200 all-electric market rate residences.
