Aspen, Colorado | C&D Waste Audit
Aspen, Colorado | Construction & Demolition Waste Audit
Construction and Demolition (C&D) debris management can be a considerable challenge for communities with limited landfill space and/or concerns about methane production in their landfill. Much of C&D debris is often bulky, heavy, and most importantly can be diverted from the landfill to be recycled or repurposed. The city of Aspen has taken this challenge head-on.
In January 2022, the Aspen City Council set a Science Based Target to reduce greenhouse gas emissions 63% by 2030 and net zero by 2050. They also set waste reduction targets to reduce organic material going to landfill by 25% by 2025 and 100% by 2050, and a reduction of all waste going to the landfill by 70% by 2050. While a typical landfill fee approach is to weigh the items going into a landfill, Aspen wanted to better calculate fees based on the environmental impact of C&D materials that should be diverted, but arrive at the landfill unsorted. Using a dataset of Embodied Carbon for materials and the U.S. Environmental Protection Agency’s Social Cost of Carbon, Lotus quantified the present cost of future environmental damage from the material’s life cycle of extraction, production, transportation, and ultimately disposal. Aspen is currently in the process of applying this metric to C&D debris that originates within the City of Aspen.
Urban Villages and APARIUM Hotel Group | Populus Hotel GHG Emissions Dashboard
Populus Hotel GHG Emissions Dashboard
Lotus worked with Urban Villages and the APARIUM Hotel Group to create a public greenhouse gas emissions tracking dashboard in Microsoft PowerBI for the Populus Hotel. The dashboard tracks real and predicted greenhouse gas emissions and offset activities from the construction and operations of the hotel over time. The dashboard includes functionality that allows for easy data updates, transparency for specific operations (waste diversion, water, energy, etc.), and tracks whether Populus has achieved their carbon positive goal. Lotus also developed back-end calculations for the quantification of greenhouse gas emissions and documenting methods and assumptions for all calculations in a user guide.

City of Fort Collins | Under-Resourced Buildings Engagement
under-resourced buildings engagement
Lotus worked with the City of Fort Collins to engage under-resourced building (URB) stakeholders. The core purpose of the engagement was to gather insight into specific tools, resources, and other support mechanisms that Fort Collins could deploy to support commercial and multifamily building owners and tenants in achieving greater energy efficiency. Lotus delivered a final report to the client that compiled current stakeholder challenges in pursuing energy efficiency and provided research-backed recommendations for programs that could overcome those challenges. The team successfully engaged all stakeholder types, including, but not limited to, affordable housing providers and nonprofits supporting affordable housing providers, multifamily tenants, business tenants and commercial developers, collecting critical data and program or policy recommendations specific to these building types.
The team applied community-centered principles throughout the engagement process to ensure reach with key URBs. Lotus developed a context guide that documented the factors and processes for the City to consider when developing the engagement strategy, resources, and support services to help URB communities make building improvements. The context guide served as the foundation for fair and defensible engagement throughout the project.
Lotus also developed a stakeholder map of URBs based on the City’s specific, data-driven definition. Our team spearheaded the creation of the matrix of data criteria defining and categorizing URBs. Following that, buildings were specifically identified and targeted for engagement based on their criteria score.
Lotus facilitated a number of engagements, including in-person focus groups, virtual focus groups, informational interviews, and listening sessions. All engagements were planned with a focus on bringing the community together, including providing participant stipends, food, and childcare while ensuring all materials and presentations were translated and interpreted into languages most appropriate for the audiences. Lotus conducted all Spanish written translations in-house. We contracted with the Community Language Cooperative (CLC) to provide interpretation services for in-person meetings in Spanish and for translation services in Vietnamese, Arabic, and Mandarin Chinese.
In addition to engagement, Lotus created a scoring methodology to categorize buildings as URBs. Lotus used building data provided by Fort Collins, affordable housing information, building condition information, energy use, demographic data, and a variety of other datasets to develop a list of URB criteria. Points were assigned to each criteria and buildings were assigned a point total based on the number and type of criteria they meet. URBs were identified based on a point threshold. Additionally, URBs were categorized into tiers to further highlight buildings with the greatest need for assistance. The scoring methodology was vetted through the engagement process and refined to ensure the scoring mechanism reflected Fort Collin’s unique context.
Once URBs were identified through the scoring methodology, Lotus developed a web mapping tool displaying all URBs. The mapping tool included filters and a data update workflow to enable Fort Collins to update the URB list and visualize URBs by tier, building type, or building size.
Colorado Department of Local Affairs (DOLA) | Strong Communities Grant Program Impact Evaluation
Strong Communities Grant Program Impact Evaluation
Lotus, in partnership with Economic Planning Systems (EPS) is completing an analysis to evaluate the effectiveness of the Strong Communities Grant Program. The Strong Communities Grant Program incentivizes the adoption of policies that promote affordable housing and sustainable development. Lotus and EPS are developing a methodology and an analysis tool that assesses the environmental and economic impacts of the land use best practices that are supported by the program. The tool will provide insight into how these best practices can reduce greenhouse gas emissions, vehicle miles traveled, household transportation costs, local government and infrastructure costs. Additionally it will quantify how best practices can increase affordable housing and influence housing costs. Understanding these impacts will allow grantees to communicate the benefits of the land use best practices and provide other communities with insight into how they could benefit from implementing these practices.
In addition to the methodology and tool, Lotus and EPS will create individualized reports summarizing results of the analysis for each grantee. Lotus and EPS will also provide case studies of a sample of projects to enable DOLA to continue to communicate the benefits of the program and the included best practices.
DOLA (Colorado Department of Local Affairs) | RENW Program Impact Evaluation
RENW Program Impact Evaluation
Lotus completed an analysis to evaluate the effectiveness of the Renewable and Clean Energy Initiative (RENW), understand how RENW can be improved, and develop information on how to evaluate future applications for RENW funding. Lotus developed two tools to complete this analysis, an impact evaluation spreadsheet that quantifies the impacts of implemented RENW projects and a cost-benefit analysis tool to assess the effectiveness and feasibility of RENW applications. These analyses assessed reductions in greenhouse gas emissions, energy impacts, and impacts to Disproportionately Impacted and Just Transition communities.
Through discussions with DOLA, Lotus identified key metrics to track and compare project impacts. An interactive evaluation tool was developed that allows DOLA to easily enter any new project data and calculates all identified metrics for all RENW projects. This work aids DOLA in making investments that advance renewable energy generation and reduce GHG emissions in Colorado.
Wheat Ridge, Colorado | Climate Action Plan Update
Climate action plan update
Lotus worked with the City of Wheat Ridge to update and formally adopt their Sustainability Action Plan. The community was the impetus for the first Plan, which was created in 2018. Lotus led the strategic analysis of the 2018 plan, which involved a comprehensive review of relevant City plans, as well as regional, state, and federal plans and initiatives. This review allowed the client to utilize existing collaborations and funding to force-multiply their sustainability efforts. Lotus also engaged City staff and key stakeholders to contextualize the 2024 plan update and identify critical opportunities, and guided community engagement to garner community input on sustainability priorities and strategies. Lotus sought to capture the grassroots, community-driven spirit of the plan and ground the plan update in the key implementation details that City staff would champion.
Commerce City, Colorado | Climate Action Grants Consultant
Climate Action Grants Consultant
In 2024, Lotus and One Small Step (OSS) worked with the City of Commerce City (C3) to support their sustainability-focused grant writing projects. Lotus has worked with C3 in the past to create their Sustainability Action Plan and support their Environmental Policy Advisory Committee. The grant writing services are a rewarding extension of this multi-year partnership, as we work to fund their sustainability goals. We work collaboratively with the city’s grants coordinator to identify opportunities aligned with the city’s goals and drive applications to completion. Lotus and OSS have helped to coordinate stakeholders to create coalitions that will improve the competitiveness of the application. Our grant writing team has also created streamlined processes to expedite the grant writing processes and has helped to create a prioritization methodology to identify strategies that will win funding. To date, we have applied for the EPA Community Change Grant, CDPHE Environmental Justice Grant, and Great Outdoors Colorado Community Impact Grant.
Boulder Housing Partners Behavioral Change Program
In concert with two other consulting firms, Lotus helped Boulder Housing Partners reach their goal of becoming the nation's first net-zero energy housing authority through an innovative occupant engagement program. The project involved outreach and education to BHP residents regarding energy consumption and energy efficiency and included in-depth work on behavioral change models that can be effective to reduce energy use.
“Hillary and Emily were amazing to work with. They jumped into a project that had been delayed several times due to a number of obstacles. They were able to resurrect the project and get it done on time and under budget. They were thoughtful, efficient and helpful on all phases of our project. I would highly recommend their services for any sustainability project.”
City and County of Denver | Home Energy Score Program Evaluation
Home Energy Score Program Evaluation
Lotus worked with the City and County of Denver’s Office of Climate Action, Sustainability, and Resiliency to conduct a program evaluation of the city’s Home Energy Score pilot program. The purpose of this program was to spur investment in energy efficiency at the point of sale of a home. Lotus analyzed survey data, home energy score data, qualitative interviews, and other data points to develop an analysis of the Home Energy Score program, an assessment of how it can support Denver’s energy reduction goals and recommendations for furthering that impact, and other ways Denver may compel homeowners to invest in efficiency at or around the point of sale. The results were delivered in a comprehensive program evaluation with a full report.
City and County of Denver | Energize Denver Equity Priority Buildings Facilitation Services
Energize Denver Equity Priority Buildings Facilitation Services
First, the City and County of Denver’s Office of Climate Action, Sustainability, and Resilience (CASR) Energize Denver program partnered with Lotus to inform equity priority building (EPB) owners about forthcoming building performance standards (BPS) for small buildings and gather insight into specific tools, resources, and other supports Denver may be able to offer to support these building owners in meeting the requirements. This project offers an overview of Lotus’s core steps and deliverables designed to foreground equity in the stakeholder engagement process: equity guide, stakeholder map, engagement plan, and final report.
First, the equity guide identifies the factors and processes to consider when developing the engagement strategy, resources, and support services to help Denver’s EPB community meet the City’s BPS. The guide (1) contextualizes the need for an equity-first approach to community engagement and program development, (2) explores existing equity-first approaches that the City has undertaken, and (3) outlines equity-first best practices and processes for use in this current relationship-building phase and for consideration in future equity-focused engagement work by CASR. The equity guide served as the foundation for equitable engagement throughout the project, as well as offered insights into potential strategies and programs that may work well for the project.
Next, Lotus developed a stakeholder map of buildings that were between 5,000-24,999 square feet. The stakeholder map forms the basis for targeting engagement efforts, ensuring the project team is aligned on who to engage and when, how, and why. All data was run through a series of filters, including the percentage of affordable housing units in the building, whether the buildings were in Neighborhood Equity & Stabilization (NEST) neighborhoods (neighborhoods identified by the City that are facing rapid change and increased cost of living, rent, labor, and materials), and building location compared to census tract. Following that, buildings were specifically pulled out based on their Equity Index.
From the research conducted for the equity guide and the stakeholder map, Lotus crafted and facilitated a number of engagements, including in-person and virtual focus groups, informational interviews, and listening sessions. All engagements were planned with a focus on equity, including providing participant stipends, food, and childcare while ensuring all materials and presentations were translated and interpreted into languages most appropriate for the audiences. Lotus also conducted all Spanish translation in house, contracted the Community Language Cooperative (CLC) to provide interpretation services for in-person meetings in Spanish, and contracted CLC for translation and interpretation services to Vietnamese.
As evidence of Lotus’s flexibility and responsiveness to the community, we focused on deploying informational interviews with key community connectors and convening or attending community meetings led by trusted community partners, such as BuCu West, DEDO, Little Saigon Business District, and Vecinos Unidos. This adaptive approach opened the doors to facilitating informational interviews with stakeholders from business improvement districts, property management, brokers, industrial contractors, and HOA boards. All engagements held space to listen to concerns and co-create solutions.
Finally, Lotus drafted a report summarizing engagements and providing recommendations and guidance to Denver on opportunities to improve services and resources for EPB owners to better compel compliance with Energize Denver requirements. The final report was written in English and translated into Spanish to reach a broader audience and continue equitable practices during the project process.

80 x 50 Climate Action Plan & Annual GHG Inventory
The City and County of Denver’s 80x50 Climate Goal: Stakeholder Report establishes a path to reduce community-wide GHG emissions by 80 percent by the year 2050. Lotus led the development of Denver’s 80x50 Plan by conducting a review of processes and plans already established by the City; conducting a needs assessment; working with a diverse network of over 80 stakeholders and community experts in the fields of energy and transportation to identify the most relevant and impactful strategies for Denver to pursue; modeling the impacts of stakeholder-identified emissions reduction strategies; and drafting a CAP that will support the City in achieving its goals. Additionally, Lotus completed Denver’s community GHG inventories for calendar years 2018-2022.
City and County of Denver | Renewable Heating and Cooling Plan (Building Electrification)
Renewable Heating and Cooling Plan (Building Electrification)
Lotus led the development of the City and County of Denver’s Renewable Heating and Cooling Plan, a roadmap for beneficial electrification in existing buildings. As part of this process, Lotus convened stakeholders from across the metro area and the State to understand the impacts of electrification on the workforce, disproportionately impacted communities, building owners of all sizes, homeowners, equipment manufacturers, and other stakeholders.
Lotus managed a variety of engagement activities ranging from surveys and one-on-one interviews, to large focus groups and workshops. In addition to the public input that helped to shape the plan, Lotus worked with subcontractors to complete a building stock and technology transition analysis and a grid and cost impact analysis. The final plan includes not only details on the technical components of electrification, but also the various levers (i.e., policy, financial, incentive, programmatic, and communications) that can be triggered to support full electrification of Denver’s applicable building stock over the coming decades.
Lotus has been lucky enough to consistently work with the City and County of Denver since 2016. Other work Lotus has completed for the City and County of Denver includes:
-Completed GPC-compliant GHG emissions inventories every year since 2017, CDP Reporting, and developed Denver’s first municipal operations inventory (2020).
-Completed a life-cycle GHG analysis for waste.
-Completed an embodied carbon analysis for buildings. (see below)
Lotus developed the maps below to use data to inform Denver’s Electrification plan. The maps showed inequities and helped identify vulnerable populations.
“Lotus partnered with Denver to create our Renewable Heating and Cooling Plan. The plan was practical and achievable yet pushed the boundary of what is possible. They excelled at project management, keeping the project partners on task. They led fun, engaging discussions with a variety of stakeholders whose insight helped shape the plan. Once all the quantitative and qualitative data was collected and analyzed, they synthesized the findings into a plan that could be understood by the public, and not just limited to those with an electrification background. We are thrilled with their work and would recommend them for future projects!”
“Lotus has been an exceptional partner in the development of a key technical roadmap that will lead to strong policy implementation. They are helping us address all the challenges and opportunities regarding building electrification in existing buildings.”
Adams 12 Five Star Schools | GHG Inventory And Related Work
GHG Inventory And Related Work
Lotus developed the first GHG emissions inventory for Adams 12 Five Star Schools for activities in 2017, which included a measurement of emissions generated from energy use, fleet activities, industrial product use (i.e., refrigerants), waste, wastewater treatment, and consumption-based sources (i.e., paper, food, and fertilizer). Lotus developed the tool to align with the Sustainability Indicator Management and Analysis Platform (SIMAP) so that the district could compare its emissions with other school districts using SIMAP. Along with the GHG inventory, Lotus provided a summary report and an Inventory Management Plan (IMP) so that Adams 12 staff could complete this work in-house in future years. Following the completion of the GHG inventory, Lotus assisted Adams 12 in auditing the district's 2018 inventory (completed in-house with the guidance set forth in the IMP) and also created a modeling tool to measure the impact of the district's sustainability goals on GHG emissions.

Denver Regional Council of Governments (DRCOG) | Climate Pollution Reduction Grant
Climate Pollution Reduction Grant
Lotus is currently working with DRCOG to fulfill the requirements of the agency’s $1 million Climate Pollution Reduction Grant (CPRG) from the Environmental Protection Agency (EPA). As part of this process, Lotus supported data collection, emissions calculations, modeling, stakeholder engagement, and strategy development and prioritization for DRCOG’s Priority Climate Action Plan. Currently, Lotus is supporting stakeholder engagement and related tasks to develop the regional Comprehensive Climate Action Plan.
To date, Lotus has led and facilitated multiple community and stakeholder engagements, and facilitated an equity subcommittee. Lotus conducted an all-day workshop that brought together representatives from communities across the 12-county region to organize implementation details for the eight PCAP strategies. The stakeholder engagement process that was deployed for the PCAP and will continue for the CCAP, has ensured that a broad constituency of community members from across the DRCOG region are engaged in, and empowered to participate in the resulting PCAP strategy implementation process. The creation and participation of the equity subcommittee as part of the PCAP process helped to ensure that the final implementation details for the PCAP strategies are informed by the communities that will be most impacted by this work.
DRCOG’s Priority Climate Action Plan was submitted to the EPA with the corresponding grant application for CPRG Implementation Funds. DRCOG secured grants funds for the Decarbonize DRCOG Program, the funding mechanism for the program related to this RFP and proposal.
YMCA of the Rockies | Sustainability Action Plan And Cost-Analysis
Sustainability Action Plan And Cost-Analysis
Lotus worked with YMCA of the Rockies to support the development of a Sustainability Action Plan that addressed the sustainability objectives of the YMCA of the Rockies strategic plan. The project actively engaged YMCA of the Rockies staff to foster a culture of sustainability within the organization and facilitate the implementation of effective climate action strategies. To support this work, Lotus conducted a comprehensive greenhouse gas emissions inventory of both campus locations, as well as emissions modeling of sustainability strategies to gain insights into YMCA of the Rockies' environmental footprint and which strategies would be most impactful. Furthermore, Lotus developed a cost evaluation of carbon emission reduction strategies for the YMCA of the Rockies. The strategies evaluated for implementation costs were also those that were modeled by the Lotus team for their anticipated carbon reduction impact. To ensure holistic implementation of the Sustainability Action Plan, Lotus worked with guest-facing staff to develop a Best Practice Guide and Lesson Plan for guest engagement in sustainability initiatives.
Finally, Lotus worked strategically with YMCA staff to bring forward a GHG reduction goal to the YMCA Board of Directors and Senior Leadership to ensure the plan and associated goal were aligned with the mission and values of YMCA of the Rockies and that the Board understood the responsibilities associated with setting a GHG target for the organization.
“Over the past year, YMCA of the Rockies has had the pleasure of working with Lotus on the creation of our comprehensive sustainability action plan. Through this process, Lotus has helped us to create a plan that aligns with our needs as a mission-based organization. Their thoughtful approach to creating a plan that encompasses all aspects of our needs has ensured that we are setting goals we feel confident in. From understanding our unique needs as a non-profit, to facilitating meaningful conversations with stakeholders of varying climate expertise, Lotus has successfully navigated through the process of developing a plan molded specifically to who we are as an organization. We are glad we chose to work with Lotus on such an important aspect of our mission.”

Identifying possible activities and associated emissions reductions.
Identifying potential barriers including such as estimated costs; awareness/attitudes; countervailing priorities/projects; technology/scale limitations; areas outside of DEN control (Electric supply limitations); and areas where DEN has partial control (vendors).
Identifying potential tailwinds such as policy and regulatory changes; funding Increases; grant opportunities; partnerships; and City and County of Denver initiatives.
Alpine Bank | Annual Sustainability Audit
Annual sustainability audit
Lotus has been collaborating with Alpine Bank since 2014 to help maintain and update Alpine Bank’s Utility Tracking Database on an annual basis, calculate emissions from facilities, and normalize energy use for the weather.
Lotus performs a quality check on Alpine Bank’s energy and water use tracking spreadsheet. The tracking spreadsheet has records of monthly electricity, natural gas, and water usage at all of Alpine Bank’s locations across the state of Colorado. Once a quality check is completed, Lotus reviews the results and errors found with the project team at Alpine Bank. Finally, Lotus writes a section reviewing the emissions and activity data trends across the organization to be included in the annual report.
“Hillary was tasked with creating a new Excel-based tool that empowered Alpine Bank’s energy managers to normalize energy data for weather from 2006 moving forward. The tool, which was designed to complement our internal energy tracking spreadsheet system, not only enables us to better understand our energy usage across our 38 locations but also helps us meet ISO 14001 goals, the results of which are published in our annual Environment Report. We continue to rely on Hillary as a key technical resource for various Alpine Bank sustainability initiatives. We highly recommend Lotus’s services for comparable projects.”
