On average, people spend almost 90 percent of their life in buildings. Because of this, we believe in the power of buildings to improve quality of life for inhabitants. Heating and cooling methods, building materials and layouts are just a few aspects of a structure that can impact people’s mental and physical health.
Healthy Spaces for Productive Work
-
Filtration: We utilize advanced air filters in our HVAC system, with some of highest rated filtration media outside of hospitals.
Paints: We exclusively use low or no-voc paints.
-
Thoughtful Tenancy: Half of our building’s square footage is common space and half of our suites are collaborative work suites occupied by an average of four organizations each.
Tenant Events: We hold frequent community events for our tenants, such as happy hours and networking events.
Intentional Design: The layout of our building encourages people to move throughout their day to access shared conference rooms, kitchens and printers.
Information Sharing: We provide multiple ways to share and access information, including curating a community listserv, newsletters and information boards.
-
In-House Choices: Our on-site cafe provides healthy and delicious drink and food options that can accommodate all dietary preferences.
Event Food Selections: Our events promote healthy options with low fat and low sugar alternatives while also providing vegetarian and vegan options.
Encourage Stair Usage: Our stairs are well lit and feature inspiring quotes nominated by tenants. For those who are able, we encourage the use of stairs as opposed to our elevator for energy conservation and health promotion measures.

These accomplishments demonstrate our ongoing dedication to your wellbeing.
Efficient & Sustainable Building Systems
The building sector consumes more than 70 percent of US electricity and emits nearly 40 percent of annual global greenhouse gas emissions, the largest of any single sector. The Alliance Center has been carbon neutral since 2008, and according to Energy Star, we use less energy than the majority of our peers.
-
Carbon Offsets: The Alliance Center offsets what it does consume and has been carbon neutral since 2008.
-
Low-Flow Installations: Our building utilizes waterless urinals, low flow faucets and showers, high efficient pressure assist toilets and drip irrigation. This results in 3.3 gallons per square foot annual consumption.
-
On-Site Compressors: These are used to cool the building during the warm summer months — as opposed to a cooling tower, which requires a continual feed of water.
Domestic Hot Water Heaters: The utilization of gas has been eliminated from the entire building through heating via electricity.
Reducing Waste Responsibly
Colorado on average has a recycling rate of 16 percent—far below the national average of 35 percent. The Center is continuously working to implement and discover ways to reduce our waste production. We currently divert over 85 percent of our waste!
-
Sustainable Products: Closed loop and high post-consumer recycled products such as Interface carpeting are a priority.
-
Agreements: Office space and event customer legal agreements include both restrictions and incentives to reduce waste.
-
Reusables: The Alliance Center provides reusable dishes and utensils for tenants to use for meals at work.
Encourage Alternative Options: We partner with caterers who can provide reusable or compostable dishes and utensils during our hundreds of annual events.
-
Dishware and Utensils: We require reusable or compostable dishware and utensils for events as well as for our on-site cafe.
Compost: Our building supports a local, woman-owned business called Wompost for our compost pick up. This amazing business also works to educate the community and provide compost services where they otherwise wouldn’t exist.
-
The Alliance Center’s Hard-to-Recycle Station takes items that aren’t normally accepted in municipal recycling streams such as lightbulbs, pet food bags and more. Located on the first floor of our building, this community resource is just one of our ongoing efforts to prevent waste from going to the landfill!
