Energy Assessments

Owen’s hallmark is energy-efficient, sustainable, and workable designs. Through our MEP and sustainable design division, Henrikson Owen, we are commissioned by the State of California for the study and implementation of numerous energy efficiency projects. Henrikson Owen has also conducted hundreds of energy audits over the last 25 years. During the course of many feasibility studies, we have identified a wide array of energy conservation measures (ECMs) for which our services have subsequently been retained for design and implementation of these ECMs, which have included HVAC improvements, building envelope insulation, glazing replacements, advanced DDC networked controls, central plant systems, day lighting and occupancy lighting controls, and energy efficient HVAC systems. Henrikson Owen also implements strategies for non-toxic materials and use of renewable energy sources, which are now dominant in school design, specifically with the California Proposition 39. Henrikson Owen specializes in Proposition 39 projects, often teaming with Contractor’s and other firms. In November 2012, California voters approved Proposition 39, which changed the State tax structure for multi-state businesses and directs the proceeds over the next five (5) years beginning with the fiscal year 2013-14, an estimated $550 million annually, to support energy efficiency and clean energy products in K-12 schools, community colleges, county offices of education, and state special schools. The following are notable projects currently underway or recently completed:

Los Angeles Unified School District | Proposition 39 Projects for the Los Angeles Unified School District (LAUSD). Henrikson Owen and Opterra Energy Services (ESCO) have teamed up and have been retained by LAUSD to provide engineering, construction, and retro-commissioning services for the Proposition 39 Projects at Four LAUSD High Schools. The four high schools (HS) are Garfield High School, Southeast High School, South Gate High School, and Washington Preparation School.

This design/build projects entail the implementation of a variety of Energy Efficiency Measures (EEMs), including HVAC system upgrades, lighting replacements, lighting controls, HVAC controls retro-commissioning, and other HVAC and lighting enhancements.

San Marino Unified School District (USD) | Energy Audits to Support Proposition 39 Projects. Henrikson Owen performed energy audits for the San Marino Unified School District to identify and recommend potential energy conservation measures (ECMs).  The intent is to use these energy audits as a basis of procuring grant funds through the Proposition 39 Implementation Program in which $428 million is available in grant funding to Local Educational Agencies (LEAs) [89% of that figure for K-12 school districts]. Henrikson Owen developed potential technical energy conservation measures (ECMs), which involved a review of the interior and exterior lighting systems (lighting replacements, daylighting controls, etc.), considered potential expansion of ECMs for additional savings, reviewed HVAC equipment / systems, and more. We analyzed the feasibility of each ECM, including estimated costs to implement, estimated annual energy savings, simple payback, and various rebates and funding sources where applicable. We also determined what funding sources (such as utility energy conservation rebates, Prop 39, etc.) were available the District for ECM implementation and incorporated these rebates into the economic feasibility analyses.

Conejo Valley Unified School District | Proposition 39 Projects. Henrikson Owen provided MEP engineering services for the Design-Build Energy Efficiency and Proposition 39 Project (HVAC Project) for the Conejo Valley Unified School District (District). The project was funded by Proposition 39 and entailed the replacements of HVAC units and DCV retrofits at five schools. The project required the demolition of all units and the MEP engineering design for their replacements. The five schools sites included Aspen Elementary School, Newbury High School, Sequoia Middle School, Westlake High School, and Wildwood Elementary School.

Conejo Valley Unified School District (USD) | Los Cerritos Middle School and Thousand Oaks High School HVAC Modernization projects. Henrikson Owen and Owen are providing architectural and engineering services for the design and assistance during construction for the Los Cerritos Middle School and Thousand Oaks High School HVAC modernization projects. The Energy Efficiency Measures are funded by Proposition 39.

Henrikson Owen is also providing architectural and engineering services as a subconsultant to Schneider Electric. The scope of A&E services will be completed in three phases.  Phase 1, development of the Basis of Design, has already been completed by Henrikson Owen.  Phase 2 is the design and DSA plan check, currently underway by Henrikson Owen.  Phase 3 is the construction to be completed by Emcor.
