Now that Zero Net Energy (ZNE) is the default for all new residential homes, we’re going to see a tremendous change in the way houses are built in California. While ZNE is a positive development for the environment and the reliability of our electric grid, not all builders will have the experience to craft homes that will excel 2020 Solar Mandate. To understand this a bit better, let’s look at two families that represent clients we see at Clarum: the Parkers and the Joneses. Matt and Sarah Parker – On the go Matt Parker is a busy guy. As a lead partner in his private equity...

Taking Sustainability Beyond Solar Since the California Solar Mandate took effect in January, sustainable building practices are on everyone’s mind. We all want to do what’s best for the environment and integrating solar energy is a great way to do that; one we’ve been endorsing for years. The mandate is a positive first step toward more sustainable practices. Over the years we’ve found, when it comes to home construction, there’s so much more to sustainability than solar. We’re seeing the cost of energy rise in a rapid way, and it’s not just in dollars. It’s important...

The 2020 Solar Mandate is here The news has been swirling for months but the day is finally here. Effective January 1, 2020 all new residential home builds must live up to the standard of Zero Net Energy. This initiative is part of California’s ongoing commitment to transition away from centralized power. The new plan aims at having 50% of California’s electricity come from clean energy sources by 2030 (NYT). It’s an ambitious goal and requiring new home construction to include solar energy is a big part of making it happen. As the calendar year moves to 2020, builders are scrambling to...

How do you decide whether to build a high-performance home or a home built to code? We can help you figure it out. Building beyond code In California, CalGreen is the baseline building code that all new home construction must follow. In terms of energy efficiency, air quality, and sustainability, there is a lot of room for improved performance by building beyond this code. And, the cost difference is not very significant. In high-performance design and construction, everyone involved in the building process takes into account energy and water efficiency, resource efficient building design...

A passive-certified home is one that employs a set of advanced building technologies to achieve extreme energy efficiency. Energy consumption is reduced by up to 90% compared to a conventionally-built home. A passive-inspired home incorporates many of the same building techniques and materials found in a passive-certified home, but without the rigor of certification and at a slightly lower price tag. Keep reading to understand the key differences between these two sustainable home options and choose which route is best for you. What is Passive-Certified? If you would like to part...

Building a green, high-performance home will typically always cost more than the same home built to standard building codes. The advantage is the long-term energy savings over the life of the home and the improved quality of life — which for many is priceless. Using California Code as a baseline of construction standards, these tables show the costs differences in initial construction costs, as well as the energy efficiency gains and ROI potential. Costs and return on investment People are often surprised to learn that a high-performance home only costs 5-10% more than a conventionally-built...

The cost of energy is rising rapidly — and not just in dollars. Our environment is also paying the price: non-renewable energy consumption, carbon emissions, and pollution. In the U.S., 39% of all greenhouse gas emissions come from buildings. We use energy — electricity, gas, and water — to keep our houses at a comfortable temperature, our showers hot, our lights on, and our gardens green, all of which generates carbon dioxide (CO2). Your carbon footprint is the sum of all emissions of CO2, which are induced by your activities in a given time frame. High-performance homes support...

These third-party certification programs define the parameters and expectations of the custom home’s ongoing energy savings. They include suggested materials, recommend efficiency engineering practices and can demand applied environmental quality controls. There are some popular and emerging high-performance home certification programs on the market today. Homeowners are increasingly familiar with...
