• NFRC 100 Applied Films, NFRC 100 Cladding Definition, NFRC 100 Complex Glazing, NFRC 100 Sightline Definition, NFRC 100 Skylight Size and NFRC 100 Table 4-3 ballots from the U-factor subcommittee.

Additionally, Jeff Baker of WestLab announced his resignation as chair of the technical committee. A new chair will be voted on in tomorrow’s board of directors meeting.

Attendees of the meeting also had the chance to view a net-zero energy building in the area on Monday evening and tour the nearby Madico Window Films plant.

At the first stop of the night, the first net-zero building, developed for several commercial business tenants, Tom Hall, building developer and manager of All Florida Management, says the energy-efficient building has generated credits with the power company.

“Since we started this project December 2, 2012, we have yet to have a power bill; in fact, we’ve only generated credits,” he said.

Hall said he projects the average energy credit at full production to be around $700 per month. Hall also said the building had submitted to platinum LEED certification and had recently received an Energy Star® designation.

Current highlights of the project include window tinting, solar photovoltaic panels, electric vehicle charging stations, a geothermal HVAC system, tankless point-of-use water heaters, independent recycling, green spaces that include indigenous plant life and rainwater harvesting.

One of the highest-performing products, noted Hall, was the Madico window films used on the building’s low-E windows.

The films, according to Hall, offered a lower-cost option that boosted the overall efficiency of the windows, helping to bring down the cost of the project without lowering the efficiency. The next stop at Madico’s plant offered attendees a glimpse into the manufacturing and assembly process for developing window films.

The NFRC’s Spring Committee Meetings run through Wednesday. Stay tuned to for more details.
