Up to 70% More Energy Efficient

HERS Rating Used by Olthof Homes You’re in the leading home energy and technology forefront with Olthof Homes. Olthof Homes uses the HERS (Home Energy Rating System) rating, which is the standard measure for a home’s energy efficiency, as designed by RESNET (Residential Energy Services Network). The HERS Index Score is used by all certified third-party energy-rating companies and can be described as a “MPG (miles per gallon)” sticker for houses. Olthof homes are up to 70% more energy efficient than the typical resale home and up to 40% more energy efficient for a new home built to code.

As an example, our Cordera plan would save an estimated $3,957 dollars in annual energy costs compared to the typical used home of the same size. Olthof Homes accomplishes this through a package of energy-saving equipment and products, coupled with superior sealing of the home and ventilation systems. These features are tested by a third-party company, which verifies that the energy efficiency standards are met. Olthof Homes provide high-performance new homes for sale and you save money every month.

The most impressive part was the workmanship. This was stylish and affordable and in the area we wanted. We were always drawn to the Olthof style. We like the openness of the kitchen and living room. She was sold on the closet space! We met a couple people on the block and everyone was so welcoming. We’re really happy that we’re here!

Jeff & Julie L.

The build quality was terrific. It’s all usable space and designed very intelligently. It’s not chopped up. In an era where people say one thing and do something completely different, you guys do everything you said you would do and when you said you were going to do it. My recommendation would be for Olthof.

John & Julie M.

The process was fun. The sunroom…that’s the biggest thing that I love. Not many homes have a sunroom like that. For me it’s the basement, for her it’s the sunroom. My friend thought the kitchen was awesome. How could you not just love to pull up to this house! I just love our house!

Matt & Christy G.

This fits me just perfectly. I like the stainless steel appliances. It’s very spacious. I like the size of the living room. Whenever I walk in the door…I’m home! I wish I had done this sooner. I could see myself living here 30 years!
