Performance Systems Development

Performance Systems Development (PSD) is a software company and consulting firm based at 40 W Evergreen Avenue in the Chestnut Hill section of Philadelphia, Pennsylvania. The organization works at the intersection of building science, energy efficiency program administration, and data management, producing software platforms and advisory services used by utilities, government agencies, program implementers, contractors, and building professionals across the United States.

Overview of the Business

PSD operates in a specialized corner of the technology sector: software built specifically for the energy efficiency and building performance industry. Rather than producing general-purpose business applications, the company develops tools that handle the particular demands of residential and commercial energy programs, including participant tracking, energy modeling, quality assurance workflows, incentive processing, and reporting to regulators.

The firm pairs this software work with consulting services. Staff members with backgrounds in building science, engineering, and program design advise clients on how energy efficiency programs should be structured, how savings should be calculated and verified, and how field data should be collected and used. This combination of technical software development and subject matter consulting is the defining characteristic of the organization, and it distinguishes PSD from vendors that supply software alone or from consultancies that do not build their own technology.

Services and Software Platforms

PSD's work generally falls into several related categories:

• Energy efficiency program management software, used by utilities and implementers to track projects from application through completion, manage rebates and incentives, and document savings claims.
• Field data collection tools designed for auditors, raters, and contractors working in homes and commercial buildings, including mobile-friendly interfaces for capturing building characteristics and equipment data on site.
• Energy modeling and analysis capability, which translates collected building data into projected energy use and savings estimates.
• Quality assurance and quality control systems that support inspection scheduling, sampling, scoring, and corrective action tracking.
• Reporting and analytics, including dashboards and data exports that help program administrators demonstrate performance to regulators, evaluators, and funding bodies.
• Consulting on program design, evaluation support, technical standards, workforce training, and building science practices.

Because energy efficiency programs vary widely from state to state and utility to utility, much of PSD's software work involves configuration and customization. Measure lists, incentive structures, eligibility rules, and reporting requirements differ between jurisdictions, and platforms in this field need to accommodate those differences without requiring a new system to be built from scratch each time.

Industry Context

Energy efficiency programs in the United States are typically funded through utility ratepayer charges, state energy offices, or federal initiatives such as the Weatherization Assistance Program. These programs are subject to regulatory oversight, and administrators must document that claimed energy savings are real, measurable, and attributable to program activity. That accountability requirement creates significant demand for structured data collection and defensible calculation methods, which is the need PSD's tools are built to address.

The company's work also touches on residential energy performance standards and rating systems used in the home performance industry. Contractors performing insulation, air sealing, HVAC replacement, and whole-home retrofits often interact with program software to submit jobs, document test results such as blower door readings, and receive approval for incentives. Software in this space has to function for field technicians working in attics and basements, not only for office staff.

Location and Setting

The Evergreen Avenue address places PSD in Chestnut Hill, a neighborhood in Philadelphia's northwest section known for its stone architecture, tree-lined streets, and the commercial corridor along Germantown Avenue. The area is served by two regional rail lines, SEPTA's Chestnut Hill East and Chestnut Hill West, both of which connect to Center City Philadelphia. West Evergreen Avenue runs a short distance from Germantown Avenue, putting the office within walking distance of the neighborhood's shops, restaurants, and coffee houses.

Chestnut Hill has attracted a mix of professional services firms, design practices, and small technology companies that prefer a neighborhood business district to a downtown tower. Street parking is available in the vicinity, and the neighborhood's commercial area includes public lots. The entrance to the business is wheelchair accessible.

Service Area

While the office is located in Philadelphia, PSD's client base is national. Energy efficiency program administration is organized largely at the state and utility level, which means work of this kind is distributed across many jurisdictions. Software deployment, training, and ongoing support are frequently delivered remotely, with travel for implementation planning, stakeholder meetings, and field training as needed. The company has historically maintained a presence in more than one location, reflecting the geographically dispersed nature of its client relationships.

Working With the Company

Prospective clients typically include:

• Electric and gas utilities administering ratepayer-funded efficiency portfolios.
• State energy offices and public agencies managing weatherization, retrofit, or decarbonization initiatives.
• Program implementation contractors responsible for day to day operation of efficiency programs.
• Home performance and HVAC contractors participating in those programs.
• Nonprofits and community organizations delivering energy services to income-qualified households.

Engagements often begin with a scoping conversation about program requirements, existing data systems, regulatory reporting obligations, and timeline. Because efficiency programs generally operate on annual or multi-year cycles tied to regulatory filings, implementation schedules tend to be planned around program year transitions.

Why the Work Matters Locally and Beyond

Buildings account for a substantial share of energy consumption and greenhouse gas emissions in the United States, and improving the performance of existing housing stock is a persistent challenge for policymakers. Older cities such as Philadelphia, with large inventories of row homes and pre-war construction, face particular difficulties in delivering retrofits at scale. Companies that build the administrative and analytical infrastructure for efficiency programs play a supporting but necessary role in that effort, making it possible to run programs that serve thousands of buildings while still documenting results with enough rigor to satisfy regulators and evaluators.
