L&S Engineering delivers experienced engineering services to bring the desired functional and systems needs of each project to reality.
Our knowledgeable team provides mechanical design, electrical engineering, sustainable design, energy modeling, and lighting design that makes any built environment perform better for the people who live, work, or learn there.
When work or a task must be accomplished, a mechanical system may be the best way to get the job done. L&S Engineers understands the complexities of mechanical engineering, designing systems and machines that meet the technical requirements of unique and demanding projects.
Examples of our mechanical design include solutions for materials handling, building systems, machine design, central plant design, heat recovery systems, and fire protection.
L&S Engineers’ specialty subsets of mechanical design include HVAC, climate control systems, and plumbing and process piping systems.
Electrical engineering is required for any building, facility or plant project. Electrical components such as power generation and distribution systems, substations, backup power systems, audiovisual systems, industrial controls and automation, motor controls, telecommunications, fire alarms and detection systems, and lighting design and controls are all designed by L&S engineers.
A focus on sustainable design is no longer considered a luxury or an ecological side benefit to a traditional project. Sustainable design is a technical requirement for many projects and can make compelling economic sense.
L&S Engineers’ sustainable engineering practices can generate long-term returns, not only for the environment, but often financially. Upgrading a facility or designing a project from the beginning to reduce its environmental impact and optimize its energy use, creates facilities with reduced impact for the long-term. And that equates to cost and maintenance savings and potential energy rebates.
L&S Engineers’ LEED-accredited engineering staff understand the criteria for achieving LEED certification for building projects. Through energy modeling and other analysis, we can show the benefits gained from lowering life-cycle cost and energy conservation through sustainable design.
L&S Engineers provide energy modeling services to determine system feasibility, financial costs over-time, energy efficiency, and emission controls—testing assumptions and providing analysis before a system is designed.
Energy modeling is gaining importance as regulations increase relating to climate change. L&S Engineers use energy modeling to show clients the future and how they can manage it to their advantage.
The best designed and constructed spaces will lose efficiency and comfort if they are not properly lit. Lighting design is an important component to any project. Determining how many fixtures are needed, where they will project, and how many lumens are required to adequately illuminate a workspace is part of L&S Engineers services.
In 2019, Washington State adopted a new energy performance standard to ensure improved energy efficiency for commercial buildings larger than 50,000 square feet. Mandatory compliance of this standard begins in 2026.
According to the Washington State Department of Commerce, the buildings sector is the state’s second largest carbon polluter behind transportation, and accounts for 27% of statewide emissions.
L&S Engineering understands these standards and works with clients to achieve compliance, lessening Washington State’s carbon emissions and improving environmental quality for everyone.
Energy Use Intensity (EUI) benchmarking determines a building’s energy use. It’s calculated by dividing the total energy used by a building over one year and dividing that figure by the square footage of the building. This benchmarking is used by property owners, facility managers, engineers and architects to assist with making energy usage recommendations and improvements to the facility.
There are many ways a building’s systems can be improved to lessen energy use and lower operating costs. L&S Engineering’s EUI benchmarking provides the information and insight necessary to realize these benefits.
