Building Performance Standards

Once you understand how your building uses water and energy, it’s time to start using resources more wisely. That is where Building Performance Standards–AKA BPS–come into play. 

BPS is a policy that requires building owners to meet performance targets for energy use by actively improving their buildings over time. Since the majority of commercial and residential building stock that will be standing in 2050 is already built, BPS will help accelerate carbon-reduction at the rate necessary to meet local and national climate action goals. From a building owner’s perspective, BPS provides flexibility as owners can use whatever technologies and operational strategies they decide are most effective and economical to meet the target. Multiple state and local governments have passed BPS policies, including Washington D.C., New York City, St. Louis, and Colorado and Washington states.
The BPS policy details for the City of Aspen have not been defined, yet. We are interested in getting feedback from community stakeholders and will be starting stakeholder engagement beginning in 2022 with the goal of collecting input to implement policies the following year, in 2023. CORE provides technical and financial resources to help aid in the process. Check out our grants and rebates to receive funding for energy efficiency projects. 

The City of Aspen wants to hear from you! Email the Climate Action Office or visit the City’s Building IQ page and let them know what you think about Building IQ.

Back It Up with a Battery

The last step to the Path to Zero is back up your renewable energy with a battery and installation of an EV charging station. 

Residential + Commercial


Battery storage helps our electric grid be more resilient and reliable by making renewable energy available in almost any conditions. These systems store electricity and use smart software to optimize how it is used. As a result, renewable energy systems are more effective. Battery storage is one of the most important tools for reducing our dependence on fossil fuels and restoring the climate.


EV chargers are a great place to hold and use the electricity you produce through renewable energy. There are four types of EV chargers out right now for residential and commercial uses. 

Level 1—Home Charging (~5 miles per hour of charging): Level 1 charging requires a grounded regular three-prong outlet. All EVs and most homes are already equipped to accommodate level 1 charging. It can add about 40 miles of range in an eight-hour charge.

Level 2—Home and Public Charging (~22 miles per hour of charging): Level 2 charging requires a 240V circuit, like the circuit used to power an electric clothes dryer. These are the most common chargers and are found in a growing number of public places. One hundred and eighty miles can typically be added during an eight-hour charge. Level 2 chargers accommodate all EVs except Teslas which require an adapter that comes with the vehicle.

DC Fast Charging—Public Charging (100 – 180 miles per hour of charging): DC fast charging will add 50 to 90 miles in 30 minutes, depending on the station and vehicle. Level 2 charging stations are compatible with most EVs thanks to adapters.

Tesla: Tesla has their own proprietary rapid charging station. The technology is similar to the DC fast charging station. It will charge a Tesla at a rate of 170 miles per half-hour of charging.

Power with Renewables

Using renewable energy to power your home is an important consideration in reducing your carbon footprint.

There are many different options when tackling the 4th step on the Path to Zero, so it is important to find the best solution for you, your home, and your region. Some examples of renewable energy are solar, wind, geothermal, and hydroelectric power. 

Energy Saving Measures Include:

Solar Photovoltaic or Solar PV generates electricity from the sun. You can put solar panels on your roof (ideally south facing) and with Colorado’s 300 days of sunshine, you can produce a lot of energy depending on the size of your array. You will produce more in the summer vs winter, and during the day vs at night, which is something to consider. It is smart to get a battery with your solar panels so you can use the energy you are producing. If not, you will put it back into the  grid and to offset (or pay for) the cost of your electricity. There are rebates, tax credits, financing, and other funding options for solar, so get more information HERE.

Solar Thermal is a system that uses the sun to heat water and produce steam that can be converted into electricity. It can also be used to meet your domestic hot water needs. When used to heat water, it can be connected directly to your hot water system.

Microhydro is a smaller hydroelectric system that can be used for a home or small community. It complements solar because in many places water flow is highest in the winter. With the amount of snow and rivers in Colorado, this is another valuable alternative to fossil fuels. 

You might picture large wind turbines when thinking about wind power, but now there are many smaller systems you can use in your home or community. According to the Colorado Energy Office, as of 2016, 17.3% of the electricity generated in Colorado is through wind.

Also known as geothermal heat pumps, ground source heat pumps use the ground as a heat sink. This system transfers heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons. They can be used for space heating and cooling, as well as water heating.

Electrify Everything

The 3rd step on our Path to Zero is to get off of fossil fuels (natural gas and propane) and onto electricity by switching your appliances and mechanical systems to all-electric.

Beneficial electrification is the process of switching from dirty fossil fuels to clean electricity in ways that benefit consumers, the environment, and the utility grid. With the electric green getting greener with renewable energy, there are many options to switch your appliances and heating systems over to electric. 

Energy Saving Measures Include:

Sometimes when we seal up a building to make it more energy efficient, we can make the air quality unhealthy for the occupants. In older leaky homes, plenty of air from the outdoors inadvertently can make its way in through the cracks, so providing a dedicated supply of fresh air isn’t as much of a concern. Once all those leaks are sealed, it’s vital to replace that air source with a balanced ventilation system. One of the most common types of systems that provides us fresh air without compromising energy efficiency is the energy recovery ventilator (ERV). This device pulls in fresh air while exhausting old stale air. As a result, it recovers some of the heat that would normally be lost.

Working like a refrigerator, but in reverse, heat pumps move heat from outside to inside. This magic box can pull heat out of the air (even with temperatures as low as -15°F) and bring it into the home, and in the summer, it pulls the hot air from the . They can be used as a space heater or cooler, and are sometimes called “reverse-cycle air conditioners”. Heat pumps can be up to 2-3 times more energy-efficient when compared to electric baseboards.

Hybrid electric water heaters use a heat pump to gain dramatic increases in energy efficiency. Rather than create hot water from electricity or gas, these units collect heat from the surrounding air and transfer it into a storage tank for later use. As long as the air has a useful amount of heat in it, these units are extremely efficient: up to four times more efficient than a traditional electric water heater.

Air Seal + Insulate

Step 2: Air Seal + Insulate

By sealing drafts and insulating walls, attics, and crawl spaces you can make the most of the heating and cooling you’re already paying for.

During your home energy assessment, the analyst will do a blower door test to see where the leaks are, but you can typically feel the draft or see daylight around your exterior door. This is the second step on our Path to Zero, and is important in keeping your heat in and the wind out. 

Energy Saving Measures Include:

Air sealing is designed to prevent unwanted air from flowing into or out of your home. This often occurs around windows, garage doors, recessed can lights, attic openings, and crawl spaces. By addressing air leakage, you also address comfort and indoor air quality issues that might be present in your home. The idea here is to seal up the home as tightly as possible, then ventilate it properly so you know where the fresh air is coming from. It can be as simple as caulking or weather stripping, but CORE can help with larger projects. 

Simply put, insulation slows heat flow. To get started, you must understand the basics of R-Values. R-Value is a measure of a material’s ability to resist the flow of heat. If you remember one thing about R-Values, remember this: higher R-Value = warmer home. Insulation comes in many forms: blown-in cellulose, fiberglass batts, and spray foam, to name a few. When insulating your home it’s important to think about all the areas of your home that you want to be heated or cooled.
