Do you own or manage a building? Are you an energy auditor?
-
If you own or manage a building, you know that reducing energy bill can drive greater tenant retention and translate to healthier bottom line. According to the US Department of Energy and a recent study published by CONSOL Energy, 3M Window Films can reduce energy usage up to 19 kwh per sq ft of windows. With typical ROI's of less than three years, building owners and managers have discovered the cost savings associated with 3M Window Films. In fact, with utility rebates, authorised 3M Window Film dealers have completed projects yielding payback in as little as one year.
Energy consultants are also pressed to look for cost-effective energy saving technologies, like 3M Window Films. They can be easily integrated into eQuest or Trace 700, increase your ENERGY STAR® Portfolio Manager™ score, and assist your building in obtaining ENERGY STAR certification.

About 3M™ Window Film
Security, solar and decorative window films can change your view of what window films can do. Solar and tinted window films save valuable energy and increase worker comfort. Security and safety window films provide shatter-resistant protection in severe weather and bomb blasts. Decorative window films add privacy and style within your building. Now you can provide sun control, UV protection, window tinting and privacy while increasing energy savings. 3M™ Window Films help improve tenant comfort, reduce hot spots and increase window safety in buildings.
For larger more sophisticated projects it is recommended to leverage hourly analysis energy simulation software. This is the typical methodology recommended for any building envelope upgrade, as the modifications to the building envelope affect many building systems. In addition, simple Excel based calculations typically do not take into account how the window performance changes as the angle of the sun changes. To do these calculations, you have two options. 3M will work with you to provide an hourly analysis model free of charge, or 3M can help enter the performance of our films into your preferred energy simulation system.
About 3M’s calculations:
3M utilises the US DOE recommended EnergyPlus™ algorithm to calculate potential energy savings. The output report is generated using a Graphical User Interface (GUI) to EnergyPlus called EFilm, but all calculations are completed by the EnergyPlus Algorithm. We recommend EnergyPlus as it can be audited by 3rd parties, including utility companies and rebate auditing firms.
Using eQuest® or TRACE™ 700:
It is important to note that if you are modeling window films in an alternative software, you should NEVER model the performance of the film by entering in a single SHGC value. In fact, EnergyPlus will not allow users to enter a single value for the performance of a window as research has shown this significantly changes the performance of the building. The SHGC of a window changes with the angle of the sun, and 3M can help you enter in the performance of our films at all angles. Contact 3M™ Technical Service for support.
eQuest is a commonly used hourly analysis building energy simulation tool. eQuest leverages the DOE-II algorithm. Though eQuest is still commonly used with-in the market, the DOE-II algorithm is no longer supported and has been replaced by the US DOE recommended EnergyPlus algorithm. TRACE 700 is a tool also used to calculate potential energy savings and is offered for purchase through Trane. Both tools will accept the angular performance data of 3M™ Window Films.

Utility companies have been incentivising 3M Window Films for years, either through prescriptive or performance based incentives. In some cases, utilities have paid as much as 40% of the project costs. 3M has a team in place that will help complete an energy audit for your building, and we will also help navigate the rebate process and work directly with your utility company on your behalf to ensure you receive the highest possible incentives available.

A number of cities and states have adopted differing policies on benchmarking requirements. Many of these policies revolve around utilising the ENERGY STAR® Portfolio Manager™. The Energy Star Portfolio Manager compares your historical energy use to other buildings of similar size in your area and rates your building on a scale of 1-100. A score of 75 or greater makes your building eligible to receive an Energy Star Rating and suggests that your building is more efficient than 75% of all similar buildings in your area.
3M Window Films can help you meet or exceed your benchmarking goals.
