Case Study: Solar Integration in Building Design in Lawside NJ

Solar integration in building design works best when it starts on the drawing board, not on the roof after construction is done.

TerraSol applied this approach to a four-building corporate campus at the Woodcrest Station Business Park in Lawnside, NJ, and the results show what's possible when solar is part of the plan from day one.

TL;DR

• TerraSol planned solar integration into a Lawnside, NJ, business park during the design phase, not after construction was finished.

• The first building (leased to IBC Technologies) carries 1,416 solar panels, generates 849,041 kWh annually, and cuts carbon output by 405 tons a year.

• Building solar into the electrical and structural plans upfront avoided rework, keeping construction costs and schedule on track.

• A second, identically sized building now powers RevZilla's operations.

• Well-designed integrated systems can cover roughly 80% of a building's energy needs and support net-zero energy goals.

• Solar integration in building design is becoming standard practice for commercial properties, not an upgrade added on later.

What Is Solar Integration in Building Design?

Solar integration in building design means planning a building's electrical, structural, and architectural systems around solar power before construction begins, instead of retrofitting panels onto a finished structure.

This includes integrated solar panels on the roof, structural framing sized to carry the system's weight, and electrical infrastructure that's ready for solar tie-in on day one.

The U.S. Department of Energy describes a related approach called building-integrated photovoltaics (BIPV), in which photovoltaic materials replace conventional building materials on roofs, skylights, facades, or windows, rather than sitting on top of them.

Why Plan for Solar Integration Before Construction Starts

TerraSol began working with the owner of the Woodcrest Station Business Park two years before construction started on the first building. That building, leased to tenant IBC Technologies, is the first of a four-building corporate campus designed for sustainability-focused owners.

It carries 1,416 solar panels, generates 849,041 kWh annually, and cuts the building's carbon footprint by 405 tons a year.

TerraSol was able to integrate the photovoltaic solar power systems into the electrical engineering plans during the design and engineering phase, which resulted in substantial cost savings as no rework is required when the solar tie-in is ready.

The structural engineering of the roof was also completed during the planning phase. This simplified solar panel installation reduced construction costs and time. These minor modifications to the planning process have resulted in substantial budget and schedule improvements, making a sustainable future of building design more accessible and cost-effective.

Another year later, and now TerraSol has completed phase two of this business park project. The second building features a solar energy system equal in size to the first. However, this will power the facilities and operations of RevZilla.

Case Study - Solar Integration in Building Design for A Commercial Business in Lawnside NJ

The demand for sustainable energy solutions will only continue to trend upward as climate change issues have accelerated over the years. Solar power is a prominent renewable energy source that is transforming how residential and commercial properties operate.

TerraSol has incorporated a progressive strategy to building design with two corporate buildings for sustainability-focused owners. The first of a four-building corporate campus that will feature photovoltaic solar power to provide clean energy for Tennant IBC Technologies, USA.

Two years prior to the start of construction, TerraSol initiated discussions with the building owner to implement photovoltaic solar power systems into the building’s architecture and engineering designs.

The building will have a carbon footprint reduction of 405 tons with 1,416 solar panels and 849,041 kWh in annual solar performance.

How Solar Integration Improves Energy Efficiency and Energy Resilience

Solar integration is essential for sustainable building design because it changes what a building does with the energy it uses and generates. A few points worth knowing:

• Well-designed integrated systems can support roughly 80% of a building's energy requirements, combining solar generation with efficient design.

• Success in solar integration involves a holistic approach that combines passive strategies (building orientation, insulation, window placement) with active strategies (solar panels, energy storage, thermal systems).

• Optimizing a building's orientation and roof pitch helps capture more sunlight and improves system output without adding equipment.

• On-site energy generation reduces electricity bills for building owners and lowers dependence on the grid, which supports energy resilience when utility prices rise.

• Incorporating solar into building design from the start helps a property work toward net-zero energy goals, rather than treating solar as an add-on after the fact.

TerraSol's work with Phoenix Contact on a 1MW solar system follows the same logic at a larger scale: design the solar system alongside the building's existing power infrastructure, not around it after construction.

Building-Integrated Photovoltaics: Solar as a Building Material

Solar integration turns a building into an active power generator instead of a passive structure that only consumes electricity. Building materials such as wood, glass, and metal panels can now incorporate solar cells directly, which means roofs, facades, and windows can double as electricity generators.

Integrated solar materials provide insulation and weather protection in addition to generating power. Solar thermal systems, which use the sun's heat for water and space heating, reduce dependency on conventional energy sources for that load specifically.

Solar components also give architects a way to design buildings that are visually striking without sacrificing energy performance — a flat black-on-black panel array reads very differently on a building facade than a bolted-on rack system.

This is also where the trade-offs show up. PV glass and BIPV windows affect how much natural light passes into a building, so designers have to balance daylighting and indoor comfort against power generation.

TerraSol's net-zero energy building project in Pennsylvania is one example of how that balance gets worked out on a real building.

What Are The Challenges to Solar Integration in Building Design

Solar integration isn't free of friction. A few recurring challenges:

• Local building codes and fragmented regulations. Permitting requirements vary by township and state, and inconsistent rules can slow down or block solar projects. TerraSol's experience navigating local permits and approvals for a Chester County solar installation shows how much groundwork this can require.

• Energy storage and supply fluctuations. Energy storage systems are crucial for managing the gaps between when solar panels generate power and when a building actually needs it. They allow continuous power availability during periods of low generation, such as overcast days or winter months.

• Upfront cost and design coordination. Integrating solar into architectural and structural plans calls for coordination between architects, engineers, and solar designers from the earliest design phase, which is a different workflow than ordering panels for an existing roof.

High-performance buildings address some of this by minimizing energy demand through efficient design first, then sizing the solar system to what's actually needed, rather than over-building.

Is Solar Integration in Building Design Just a Trend?

No. Rising energy costs, stricter local building codes, and increased energy demand are pushing solar integration toward becoming standard design practice rather than a trend that fades.

Businesses such as those at Lawnside's Woodcrest Station Business Park, commercial properties working through solar incentive programs in Delaware, and small businesses exploring whether solar panels are worth the investment are all part of the same shift: treating solar as infrastructure, not an accessory.

That shift also shows up in how communities support it. TerraSol's recognition as a top commercial solar installer in the PECO region and projects like the SunPower carport installation in Atlantic City point to growing demand for solar across commercial, industrial, and public sites, not just isolated projects.

The Bottom Line

In summary, TerraSol's approach to designing with solar energy in mind is an excellent illustration of how businesses can take a proactive stance toward sustainable design.

TerraSol’s new construction solar systems demonstrate the advantages of integrating solar energy into the building design from the beginning. By designing buildings with renewable energy sources in mind, we can create a more sustainable future.

As more businesses switch to solar to manage rising energy costs, and more property owners look at eco-friendly building design from the ground up, solar integration in building design is becoming a standard part of how commercial properties get built, not an upgrade tacked on afterward.

Frequently Asked Questions

What is solar integration in building design?

Solar integration in building design is the practice of planning a building's structure, electrical systems, and architecture around solar power before construction starts, so the building is built ready for solar rather than retrofitted for it later.

How much of a building's energy needs can solar integration cover?

Well-designed integrated systems can support approximately 80% of a building's energy requirements when solar generation is combined with efficient building design and passive strategies.

Is solar integration more expensive than adding panels later?

Planning for solar during design and engineering typically reduces costs. TerraSol's Woodcrest Station Business Park project avoided rework by including solar in the electrical and structural plans from the start, which kept the project cost-effective compared with retrofitting later.

What's the difference between rooftop solar and building-integrated photovoltaics (BIPV)?

Rooftop solar panels are mounted on top of an existing roof. BIPV replaces conventional building materials like roofing, facades, or windows with photovoltaic materials that generate electricity while still serving as the building envelope.

Can solar integration help a building reach net-zero energy goals?

Yes. Incorporating solar generation into a building's design, alongside energy-efficient materials and systems, is one of the more direct paths toward net-zero energy performance. TerraSol's PV solar and energy storage project for home energy resiliency and its Montgomery County, PA commercial solar work both apply this principle at different scales.
