Located on just more than three acres, Washington Village is a net-zero community in the heart of North Boulder, Colorado. One of the homes uses a very tightly sealed building envelope and a ground source heat pump to deliver net-zero performance. This case study looks at the systems used to make this such a high performance home.
This diagram from PowerWise Systems shows the complete building intelligence system that allows homeowners to monitor circuit-level electricity, building environment conditions, a wide variety of flow, fluid level, water, and gas. Customers can also monitor performance of PV, wind power,...
The EPA says more than 40 percent of the energy use in a home goes to heating and hot water. We can reduce this energy use by up to 50 percent through more efficient heating. This guide reviews some of the key products and technologies that directly address the major energy uses in the home.
Photovoltaic (PV) panels and other onsite renewables generate DC, but these systems still incur losses. Grid-connected renewables require an inverter to convert their DC to AC for the grid, even though it is changed immediately back to DC for onsite use.
Home solar power systems can be a great way to reduce home energy costs and greenhouse gas emissions. But is solar power right for your home? Learn about the latest advances in residential solar power systems and best practices for implementation.
