1. Why Energy Efficiency Matters for Shops

A well-built shop shouldn’t just be a shell—it should be a space that works hard without wasting energy. Energy-efficient shops offer:

• Lower heating and cooling bills

• Better temperature control year-round

• Less moisture and condensation issues

• Improved resale value

• Greater overall comfort and usability

Plus, in Spokane’s variable climate, a poorly insulated shop can become freezing in winter and sweltering in summer.

2. Start with the Right Building Envelope

The building envelope is your first line of defense. This includes the walls, roof, windows, and doors that separate indoor and outdoor environments. We focus on:

• Tight framing

• Quality vapor barriers

• Durable siding and roofing

• Thoughtful orientation to sunlight and wind

A strong, sealed envelope reduces heat transfer and boosts energy performance right from the start.

---

3. Insulate Like You Mean It

Insulation is your most powerful tool for energy efficiency. We recommend:

• Spray foam for high-performance air sealing and R-value

• Batt insulation in framed walls and ceilings for cost-effective coverage

• Rigid foam board under slabs and on metal panels

Insulate the roof, walls, and even the floor if you're using your shop year-round. A small upfront investment pays back quickly.

4. Seal Out Drafts and Air Leaks

Even the best insulation won’t perform if air leaks go unchecked. That’s why we:

• Seal around windows and doors

• Use weatherstripping and foam gaskets

• Caulk panel seams and wall joints

• Install insulated, tight-fitting garage doors

Stopping air leaks helps your HVAC system work smarter, not harder.

---

5. Use Efficient Windows and Doors

Windows and doors are often overlooked in shop design, but they play a big role in efficiency. We suggest:

• Double- or triple-pane windows

• Low-E coatings to reflect heat

• Insulated overhead doors

• Steel or fiberglass entry doors with thermal breaks

These upgrades keep conditioned air in—and Spokane’s extremes out.

---

6. Choose High-Efficiency Lighting

Lighting is a common energy drain in shop buildings. We recommend:

• LED fixtures for long life and low power draw

• Motion sensors or timers to cut unnecessary usage

• Task lighting to avoid over-lighting the entire space

LEDs can reduce lighting costs by up to 75% compared to incandescent or fluorescent options.

---

7. Go Smart with Heating and Cooling

If you’re planning to heat or cool your shop, go with energy-efficient systems:

• Mini-split systems for zoned comfort and low energy use

• Radiant floor heat for consistent warmth and comfort

• Programmable thermostats for smarter control

Insulation + a right-sized HVAC system = serious long-term savings.

---

8. Take Advantage of Natural Light

Adding windows, skylights, or translucent wall panels can reduce your need for artificial lighting during daylight hours. Not only does it cut energy use—it makes your shop feel more open and welcoming.

We help you design for orientation, sunlight angles, and proper shading to keep glare and heat gain under control.

---

9. Consider Renewable Energy Sources

If you’re looking long-term, solar panels can turn your shop into an energy producer. Spokane gets enough sun for solar to make sense, especially if your shop has:

• A large south-facing roof

• Low daily power demands

• Net metering access with your utility

Even a small solar setup can offset lighting or HVAC loads over time.
