Empowering Sustainability: Aligning with the Energize Denver Program and Adhering to Colorado Regulation 28
Commercial building owners in Denver must comply with the Energize Denver Program, a mandate requiring businesses to reduce their carbon footprint by a specific deadline. This program helps property owners meet the city’s energy efficiency standards, ensuring they are in full compliance with local regulations. By following the Energize Denver Program, commercial building owners can both reduce their environmental impact and stay on track to meet required deadlines for a more sustainable future.
Denver’s Energize Program is a city-driven initiative to boost energy efficiency in large buildings across the area. Colorado Regulation 28, also known as “Building Benchmarking and Performance Standards,” mandates that owners of certain properties meet targeted energy usage and emissions reductions, supporting the state’s ambition to reduce greenhouse gases by 50% by 2030. This regulation specifically applies to multifamily residential and commercial properties over 50,000 square feet, setting benchmarks for energy use that encourage sustainable practices among property and business owners.
Compliance with Colorado Regulation 28 is essential for contributing to environmental sustainability and advancing Denver’s goal of reducing carbon emissions. By participating in the Energize Denver Program, businesses can not only demonstrate their commitment to sustainability but also benefit from energy efficiency improvements that lower operational costs. This positions businesses as leaders in green building practices while helping the city achieve its climate targets.
To comply with Colorado Regulation 28, businesses can upgrade to energy-efficient windows, reducing heat loss and gain while improving overall energy performance. These upgrades are essential for meeting energy use and greenhouse gas reduction targets. At CWS Exteriors, Windows, & Siding, we provide window solutions designed to ensure compliance with state regulations. Our energy-efficient windows not only help businesses meet environmental standards but also deliver long-term savings by optimizing energy usage.

Revolutionizing Building Efficiency One Window at a Time
As energy efficiency becomes a top priority for building owners, Low-E (Low Emissivity) glass is gaining recognition as a powerful solution. This specialized glass, with its advanced coatings, not only enhances temperature control but also protects interiors from damaging UV rays. Originally designed for colder climates, Low-E glass is now a smart, cost-effective choice for buildings in a range of regions, offering benefits for both hot and cold weather.
Low-E glass is glass coated with a microscopically thin, transparent layer that reflects infrared (heat) and ultraviolet light. This innovative coating allows visible light to enter while keeping out the parts of the solar spectrum that increase heat or fade interiors. Low-E glass mirrors the insulating effect of a thermos by using a reflective coating—often silver-based—to reflect heat, keeping it either inside or outside depending on the season.
Low-E glass provides energy efficiency by reducing the need for heating and cooling systems, lowering energy costs, and creating a stable indoor climate. Beyond saving on energy, it offers UV protection to prevent fabrics, flooring, and furniture from fading over time. By blocking infrared heat and UV light, Low-E glass ensures optimal light without the added heat, making it a popular choice for sustainable, comfortable buildings.
Building owners interested in Low-E glass can explore options with CWS Exteriors, Windows, & Siding, a trusted provider of energy-efficient window solutions. CWS offers a variety of Low-E options for covered buildings under the Regulation 28. By connecting with CWS, building owners can access professional guidance and expert installation services to implement the ideal Low-E solution for their properties.
Looking to Finance Energy-Efficient Upgrades? Ask CWS Exteriors, Windows, & Siding About C-PACE Options
If you’re concerned about the upfront costs of upgrading your windows, C-PACE (Commercial Property Assessed Clean Energy) provides a valuable solution. This innovative financing program enables owners of commercial, industrial, multifamily, and agricultural properties to fund energy-efficient upgrades with minimal to no upfront expense. By utilizing C-PACE, you can make crucial improvements, like installing energy-efficient windows, that not only improve the comfort and sustainability of your building but also reduce long-term energy costs. What makes C-PACE particularly attractive is its flexibility, allowing you to pay for these upgrades over time through property assessments, aligning your payment schedule with the energy savings you generate. This financing option empowers property owners to invest in their buildings’ future without the burden of significant initial outlays. As of 2023, the C-PACE program has helped finance 120 projects in 39 Colorado counties, facilitating over $250 million in private sector investment in clean energy improvements. CWS Exteriors, Windows & Siding can help walk you through this process so give us a call. How C-Pace works:
Financing is repaid through a voluntary special assessment (lien) on the owner’s property tax bill.
The lien attaches to the property and transfers with ownership.
Owners can select long-term financing (up to 20 years) for as much as 100% of improvement costs. This arrangement spreads the cost of clean energy improvements over a longer period than traditional debt financing.
Property owners can also arrange financing directly with one of the program’s capital providers, or can secure their own capital provider to purchase the Colorado C-PACE lien.
