Our team of in-house engineers has deep experience in both new multifamily construction design and existing multifamily retrofit, and they understand how to coordinate effectively with multiple stakeholders. We have experience developing and retrofitting both low-income and market-rate multifamily units.

We work with:

• Developers
• Architects
• Engineers
• Energy and LEED Consultant
• General Contractors
• Construction Managers
• PPA Finance Companies
• Independent Power Producers

Whether you are developing a new multifamily unit or outfitting an existing building, renewable energy solutions such as solar PV, solar hot water, battery storage, and EV charging offer a number of benefits:

• Reduce energy use
• Save money on utility bills
• Increase property value
• Meet sustainability goals
• Attract and retain residents
• California solar tenant billing

California Solar Tenant Billing

Solar tenant billing enables owners of multi-tenant properties to generate another stream of rental income. On-site solar energy is substantially cheaper than residential electricity from the utility, building owners can provide their tenants with a ~10% discount on energy from the utility rate while still earning a substantial return on their investment.

For example, the cost of energy for Building B from the utility is $0.35 per kWh. After installing renewable energy, the cost of onsite energy is $0.04 per kWh. Though the cost of energy went down for Building B by putting solar on the roof, the owner can still provide a discount to tenants at $0.32 per kWh while only paying $0.04 per kWh for all of Building B’s energy usage. By implementing California solar tenant billing, owners can generate an additional $500 to $1200 per unit per year, accelerating payback of the solar installation and generating additional revenue for over 20 years increasing NOI and property value.

The Title 24 California Solar Mandate

California’s New Construction Solar Mandate via Title 24 building code requires all newly constructed commercial and high-rise multifamily buildings to install Solar PV and Battery Storage Systems. The required Solar PV and Battery system sizes are based on the conditioned floor area, climate zone, and building type and will be sized to meet approximately 60% of the building’s electric load. This new Title 24 California Solar Mandate will apply to projects that submit for permits on or after January 1, 2023.
