Application to replacement fenestration products

Where some or all of an existing fenestration unit is replaced with a new fenestration product, including slash and glazing, the replacement fenestration unit shall meet the applicable requirements for U-factor and SHGC.

Building Envelop Requirements

Building thermal envelop assemblies for building that are intended to comply with the code on a perspective basis, in accordance with the compliance path described in Item 2 of Section C401.2, shall comply with the following:

The opaque portion of the building thermal envelop shall comply with the specific insulation requirements of Section C402.2 and the thermal requirements of either the R-value –based method of section C 402.1.3; the U-, C-, F-Factor-based method of Section C402.1.4; or the component performance alternative of Section C402.1.5

Roof solar reflectance and thermal emittance shall comply with Section C402.3

Fenestration in building envelop assemblies shall comply with Section C402.4

Air leakage of building envelop assemblies shall comply with Section C402.5

Perspective Compliance

Vertical Fenestration: New vertical fenestration area that results in a total building fenestration area less than or equal to that specified in Section C402.4.1 shall comply with Section C402.4. Additions with vertical fenestration that result in a total building fenestration area greater than Section C402.4.1 or additions that exceed the fenestration area greater than Section C402.4.1 shall comply with Section C402.4.1.1 for the addition only. Additions that result in a total building vertical glass area exceeding that specified in Section C402.4.1.1 shall comply with Section C407.

Skylight area

New skylight area that results in a total building fenestration area less than or equal to that specified in Section C402.4.1 shall comply with Section C402.4. Additions with skylight area that result in a total building skylight area greater than Section C402.4.1 or additions that exceed the skylight area greater than Section C402.4.1 shall comply with Section C402.4.1.2 for the addition only. Additions that result in a total building skylight area exceeding that specified in Section C402.4.1.2 shall comply with Section C407.

The $7 Trillion AI Boom Is Turning Into The Energy Trade of the Century

You might think that Shark Tank’s “Mr. Wonderful,” Kevin O’Leary, is betting it all on AI, but he is not. He is betting on the $5+ trillion in infrastructure required to run it, and that’s where big capital is flowing now. And he’s betting on Bitzero (NASDAQ: AIBZ) to be one of the first to break AI’s biggest chokepoint: power. Bitzero was looking further ahead while most of the rest of the market was narrowly focused on AI software and semiconductors. As a result, on May 5th, Bitzero…

One of Texas' Oldest Oil Plays Is Running Dry

The Eagle Ford shale play has shown remarkably consistent crude oil production and rising natural gas output in recent years. A formation beneath the Eagle Ford has been producing for nearly a century, but now it has its remaining resources nearly exhausted. The Buda Limestone formation, which lies beneath the Eagle Ford Group, has limited remaining oil and gas resources, the latest analysis by the U.S. Geological Survey (USGC) showed this week. Technically recoverable resources at Buda Limestone are estimated at 184 billion cubic feet of gas and…

China Is Quietly Winning the Clean Energy Trade War

China’s clean energy dominance is growing. Buoyed by the skyrocketing energy needs and future projected demands of the artificial intelligence boom, clean energy projects are getting greenlit at a breakneck pace. And those projects depend on cheap Chinese clean energy components, as Beijing has near-total control of global supply chains for clean energy tech including solar panels and lithium-ion batteries for electric vehicles as well as energy storage systems. As a result, Chinese clean energy exports are going gangbusters in virtually…

NASA Eyes Moon Base Powered by Solar Panels and Nuclear Reactors

With major plans for space travel, several governments are proposing lunar energy production, including solar and nuclear projects. In May, NASA announced plans to send robotic landers, hopping drones, and vehicles to the moon as part of the United States government’s plans to develop a lunar base. NASA is expected to develop the machines alongside Intuitive Machines, Astrobotic, Blue Origin, and Elon Musk’s SpaceX. The United States aims to land its astronauts back on the moon before President Donald Trump leaves office in 2029, 60…

The AI Power Crisis Is Creating a Massive New Market for Fuel Cells

Data center developers are scrambling for reliable power, turning away from congested grids and toward on-site fuel cells. Rystad Energy research and analysis projects a tenfold increase in fuel cell market revenues by 2030, rising from around $2.8 billion in 2025 to roughly $30 billion, as AI computing demand drives unprecedented growth in data center construction. A contracted order book of approximately 9 gigawatts (GW), including framework agreements with Oracle, AEP, Equinix, and Brookfield, points to growing confidence among major operators…
