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.

Sector: Multi-family
Client: Vulcan Inc.
Project Size: 238,000 sf

Services

  • Informing Design
  • LEED-NC Energy Modeling
  • LEED-NC Measurement and Verification

The Martin is a new, 188 unit high-rise apartment development in the Midtown neighborhood of Seattle, Washington. The project has been certified Gold under the LEED-NC 2009 rating system. The design utilizes a range of energy and water efficient systems, such as water loop heat pumps, high-efficiency space and water heating boilers, EnergyStar appliances, low-flow plumbing fixtures, and lighting occupancy sensors in most all common spaces. Energy modeling was used to inform the design of ventilation systems by evaluating the impacts of variable-flow corridor ventilation and super-efficient whole house fans. Finally, utilizing the process of measurement and verification, the actual performance of the Martin's design was evaluated, thereby closing the loop on the design of this exceptional project.

 

Green Communities Project

Client: Bellingham/Whatcom County Housing Authority
Architect: RMC Architects
Project Size: Three building sites, totaling 260,000 sf

Services

  • Utility Bill Analysis
  • On-site Performance Assessment
  • Model Calibration
  • 90.1 Appendix G Energy Modeling
  • Measurement and Verification (M&V)
  • Utility Incentive Coordination

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.

  • Informing design
  • LEED for Homes - Midrise Energy Modeling

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.

UW Husky Stadium Renovation and Team Facilities

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.
