360 Analytics was engaged by the design team to provide energy modeling services to inform HVAC system selection and LEED-NC energy modeling.  During the design development phase, the study focused heavily on comparing two HVAC system options: 1) Packaged variable air volume (VAV) versus 2) a high-efficiency variable refrigerant flow (VRF) system with dedicated outdoor air system (DOAS).  Because this analysis occurred early in design, 360 Analytics worked closely with members across the project team including design professionals, contractors, and subs to ensure the systems and performance modeled closely represented a fully designed system.  The analysis illustrated the significant energy/maintenance savings, CO2 emission reductions, and additional LEED points, while a simple financial model revealed an acceptable payback period.

Sun Tower is a 200 unit, affordable senior living and assistance community located in the sunny heart of Washington State.  The developer and architect team, inspired by some of the work presented on the success of the Green Communities Project, engaged 360 Analytics to help identify and prioritize energy and water efficiency updates as part of a major renovation.  360 Analytics completed a site assessment, including a robust sampling of ventilation and water fixture flow rates.  Two years of energy, water, and solid waste utility bills were compiled, and degree-day regression models were developed to identify the heating, cooling, and base load energy flows.  Using the site measurements and energy monitoring data from past projects, the models were further refined to identify other end-use flows, such as elevators and hot water heating.  The analysis gave the owners and design team a better understanding how utility dollars were being spent, and is being used to prioritize retrofit funds. In addition, 360 Analytics design review led to identifying a suitable heat pump HVAC replacement option, available for a negligible additional cost over the electric resistance option.

The Arbora Court Apartments is a project being realized by Bellwether along with University Christian Church (UCC). It is a new, 133 unit affordable, housing project planned for the bustling University District of Seattle. Leveraging a grant from Enterprise Green Communities, Bellwether Housing assembled a robust team of consultants, designers, and a contractor, Walsh Construction, to develop and evaluate a large package of energy, water, and waste saving strategies early in the design. 360 spearheaded the utility bill analysis of two, recently built, similar buildings in the owner’s portfolio, and used the existing building information to inform and tune the occupant dependent loads assumed for the UCC design analysis. The eQUEST energy model developed by 360 for the project was used to calculate the savings of over 30 different efficiency measures, bundled into multiple packages. 360 worked closely with Bellwether and Walsh to compile the construction costs, utility costs savings, and utility incentives into a comprehensive financial analysis.

The goal of this analysis was to evaluate the energy consumption and cost impacts of installing new glazing units as part of an overall retrofit of the sloped glazing system at the top of the Tower. The process started with an initial site visit, review of as-built drawings, and confirming operational/HVAC assumptions with the building manager. Using this information, a whole-building energy model of the upper floors was created, including descriptions of VAV air distributions systems, central plant equipment, and daylighting controls. Detailed simulation inputs for the existing and various new glazing options were generated using the WINDOW/OPTICS programs, and the impacts of each selection on HVAC and lighting energy consumption evaluated.

The Green Communities Project is a major renovation to three public housing authority-owned multi-family towers located in Bellingham, Washington. Funded by a $9.9 million grant from the U.S. Department of Housing and Urban Development (HUD)/American Recovery and Reinvestment Act (ARRA) stimulus funding, the project’s stated goal is to “facilitate transformational energy efficiency and ‘green’ retrofits to substantively increase energy efficiency and environmental performance of public housing properties and thereby reduce energy costs, generate resident and PHA energy savings, and reduce greenhouse gas emissions attributable to energy consumption.”

For this project, 360 Analytics started with an in-depth evaluation of existing building performance, including regression analysis of historical utility data, physical building audits, and targeted short-term sub-metering to develop calibrated, baseline energy models. These models were leveraged to evaluate the impacts of individual energy conservation measures, as well as complete a 90.1-2004 Appendix G analysis to demonstrate grant compliance. Ongoing activities include development and execution of an IPMVP compliant measurement and verification protocol, continued analysis of utility meter and sub-metered energy use data and coordination of utility incentive applications.

The H2O Apartments are an innovative Seattle apartment complex that targeted LEED Gold certification. Early emphasis on energy savings enabled architectural concepts as well as mechanical and electrical solutions to contribute to the predicted energy savings of this project over conventional designs. Moving away from the traditional double-loaded corridor concept, exterior entries to all apartments significantly reduce the typically high energy consumption associated with common areas in multifamily buildings. High-efficiency windows, lighting, and appliances also contribute to the predicted performance.

The University of Washington Husky Stadium Renovation and Team Facilities restores iconic Husky Stadium to one the finest college football venues in the country. In addition to new seating, suites, and other spectator amenities, state-of-the-art team operations and sports medicine facilities have been efficiently integrated into the renovation of the program.

Energy modeling was initially employed to evaluate compliance with the 2009 Seattle Energy Code via the Systems Analysis (RS-29) approach. This required close coordination with the design team, as well as proactive communication with code reviewers throughout the permitting process. The same detailed models were used to evaluate impacts of various envelope revisions, and ongoing work includes preparing ASHRAE 90.1-2007 Appendix G energy models to determine LEED-NC 2009 Energy and Atmosphere (EAc1) performance rating.
