Who We Are ~ What We Do

Our company, based in Duluth, Minnesota, has been building a reputation for our work designing solutions that address energy problems in homes since 1994. Conservation Technologies' background is in building construction, the performance of buildings, and energy issues in general. When builders moved toward more air-tight and better-insulated building construction techniques, we were there for the various side effects of that transition. Tighter construction, as well as the use of new materials with properties different than those traditionally used, led the industry into a stream of problems.

Elevated interior relative humidity levels, inconsistent energy performance, indoor air quality problems, back drafting combustion equipment and bulk water intrusion are all examples of issues that have kept the building performance industry on its toes over the last few decades.

Conservation Technologies' is researching the growing evidence of rapidly approaching energy supply problems. We are trying to move the building performance industry in a direction that focuses on energy issues in addition to problems in buildings.

Conservation Technologies sells energy efficient building supplies and Venmar heat recovery ventilation systems. We also consult in building design and performance. We work with various utilities on the design and delivery of energy efficiency and conservation programs.

Conservation Technologies has a comprehensive support team that includes sales, installation and technical support professionals. We serve a growing area in the upper Midwest from our Duluth office. If you have any questions or want more information, come into our showroom and allow our staff to answer all your questions.

Why Solar

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar


A Smaller Footprint

According to the Environmental and Energy Study Institute (EESI), there are 1.5 million solar water heaters already in use in U.S. homes and businesses. Since solar water heater systems can work effectively in just about any


Go Green

While solar heating and cooling can be a relatively inexpensive source of electrical energy where grid power is inconvenient, unreasonably expensive to connect, or simply unavailable the cost of solar electricity is falling, solar
