Project Update

The Mutual Housing at Fairview Terrace affordable senior housing project kicked-off in August of 2022. Early on, the design team met with community members and local organizations to understand the options and approaches best suited for a project in this specific neighborhood of Stockton. The design team studied the history of the City of Stockton, the needs of the neighborhood and how to implement the robust energy and sustainability goals in order to wrap up schematic design at the end of 2022.

Since the project Design Development kick-off at the beginning of 2023, the design team made progress on space allocations for various support functions, architectural floor plans, elevations, MEP schematics and defined an overall strategy to meet the established target Energy Use Intensity (EUI) of 24 kBtu/sf-yr along with on-site PV for net zero energy. To achieve high energy performance, the architectural team implemented external window shading appropriately designed to maintain visual comfort and reduce solar gains by up to 50% in cooling season, while preserving access to solar gains during winter for passive heating benefits. In addition to dwelling units, secure operable window provisions were also made for common areas including the community room, offices, breakroom and lobbies to utilize natural ventilation when weather and air quality permits. The design team researched and identified low-GWP HVAC equipment and a heat-pump water heater, an EV charging system that enables easy scaling-up for the future and dialed-in some details of how the innovative technologies like Hybrid Solar Plus Storage Cogeneration, HVAC optimization controls, plug load management controls would be implemented to achieve project and EPIC goals. With the help of the client, the team has also identified tier 1 and tier 2 critical loads.

The big challenges included integrating emerging technologies with conventional design and establishing overall clarity between design team members on their individual scope of work. An example of the challenges faced was the MEP team’s effort in understanding how the predictive-adaptive controls from the HVAC optimization technology interface with the conventional mechanical and electrical control system, and how the solar cogeneration system would be integrated with conventional plumbing design. A major goal for early 2023 is to evaluate battery sizes and develop microgrid design. Furthermore, the overarching goal early this year is to add details to the drawings and specifications regarding emerging technologies being implemented on the project.

The Issue

The need for affordable housing throughout California is critical. There is no greater need than in Stockton; one of the state’s poorest communities. One out of every 4.5 residents of its approximately 300,000 residents live in poverty--dramatically higher than the 15.1 percent State average. Per the City’s Housing Element, 7,000 (41 percent) of Stockton’s 17,000 senior households 65 years of age or older have a housing-cost burden. Many seniors’ only source of income is Supplemental Security Income (SSI) which currently provides $794 per month for an individual and $1,191 for an eligible couple. As such, SSI recipients are likely to have difficulty finding housing that fits within their budgets. Additionally, 42 percent of Stockton’s seniors are disabled. Many do not have the financial and/or physical capacity to own and/or drive a car and thus are reliant on public transportation to complete their daily tasks such as getting to the grocery store and medical appointments. The built environment can exacerbate this problem by construction practices, location of buildings and CO2 emissions from building operations. This can cause global and regional air quality issues as well as indoor air quality challenges that can greatly impact the health and well-being of occupants. Green buildings, energy efficient technologies, and housing near amenities do exist, but are often not available for lower income households.
Developers designing and constructing affordable senior housing today are currently constrained by market conditions and budget impracticalities and are thus disincentivized to explore and ultimately include innovative, emerging and new technologies in their projects. Sustainable design and construction techniques, advanced building materials, and technological advancements are slow to break into the market.

Project Innovation

This project will assess different existing and emerging grid-interactive and zero-emission technologies, energy efficiency measures, and passive building features to design a mixed-use development for affordable senior housing and office space. The project team will 1) define technical equipment performance specifications and configuration options; 2) simulate baseline energy consumption; 3) finalize a variety of use-cases characterized by different use scenarios, including but not limited to resiliency, demand reduction, bill savings, and cost effectiveness; 4) assess the potential impact of various control strategies; 5) assess different funding mechanisms and incentives to help finance the project; and finally, 6) finalize schematics for the mixed-use development.

Project Benefits

Lower Costs

Affordability

The project supports developers in making more informed choices, lowering the possibility of unexpected costs during construction. Additionally, if built-out it could lower costs with energy efficiency measures, onsite renewable energy and storage technologies that will help offset the building owner and tenant energy bills.

Equity

Equity

The project provides all-electric, energy efficient, and grid-reliability innovations to income-qualified tenants.

Greater Reliability

Reliability

The project will help increase greater electricity reliability by providing reductions in daily peak demand through on-site renewable energy coupled with energy storage. Additionally, microgrid control technologies will provide power for Tier 1 critical loads during power shutoff events.
