This project demonstrates three innovative bundles of pre-commercial technologies. The technology bundles were strategically developed through a systems-level approach to address the most energy-intensive areas in commercial buildings. These include: (1) Chilled Water Plants: Optimized all-variable-speed chilled-water (CHW) plants utilizing alternative refrigerant chillers. (2) Office and Exterior Space LED fixtures with integrated advanced controls, advanced building management system (BMS), and plug load controls controllable for demand response (DR), and off-grid, exterior, LED lighting in the parking lot, and lastly (3) Advanced laboratory ventilation, fume hood exhaust, and direct current (DC) lighting systems.

This research will examine several high aspect ratio (15:1) cylinders, (smooth, roughened and grooved) in a wind tunnel test that specifically measures dynamic response to simulated boundary layer flow. Both along- and cross-wind response will be measured for a range of wind speeds to determine the nature of the loading and in particular the effect of the grooves on the loading and axial wind speeds. This will provide the necessary data to develop a full proposal to study the bio-mimicry aspects of this work to the aerodynamics of tall buildings.

This project picks up on an ET project with long-term performance monitoring of a cold climate heat pump in Fairbanks, AK. In the United States, approximately 14.4 million dwellings use electricity for heating in cold and very cold regions, consuming 0.16 quads of energy annually. A high-performance cold climate heat pump (CCHP) can result in significant savings over current technologies (greater than 70% compared to strip heating) and in annual primary energy savings of 0.1 quads when fully deployed, which is equivalent to a reduction of 5.9 million tons of annual carbon dioxide emissions.

ClearStak will work with Heating Systems, LTD (Thermo-Control), a biomass-fired heating device manufacturer in Cobleskill, NY, to replace the existing controls on the Model 600 wood burner with non-proprietary components and software. This will be completed using their existing Intelligent Biomass Controller (IBC) to optimize combustion efficiency. The IBC allows for wireless connectivity, giving end-users access to remote monitoring capabilities, data reports, and alert notifications. Following the successful modifications to the system and the integration of the IBC, the entire system shall be tested using the Method 28WHH for Certification of Cord Wood-Fired Hydronic Heating Appliances With Partial Thermal Storage (Method 28 WHH-PTS) method at an EPA accredited testing laboratory. The project will be completed with UL testing and certification of the entire system, resulting in a commercial-ready product

This project will develop and demonstrate a Climate Appropriate Air Conditioning system for commercial buildings. The heart of this system is an intelligent HVAC controller that processes signals from building sensors and system feed-back to maximize system efficiency. This control system will manage two technologies to optimize building energy and peak demand reduction. Getting fresh air into commercial buildings is a code requirement. However, the ingress of hot air into a cooling system and vice versa presents an inefficiency problem. This project will evaluate heat-recovery ventilation (HRV) and indirect evaporative cooling (IEC) to decrease the temperature of the incoming air in the summer and increase it in the winter. Both technologies can be intelligently controlled by the building controller to reduce cooling and heating costs. This project will also research low global warming refrigerants for commercial buildings

Overall goal is to facilitate commercialization of this technology in the Pacific Northwest. This is a continuation of the previous and current work with the Sanden split system heat pump water heater (HPWH). Sanden will provide a UL listed version of its split system HPWH designed for marketing in the US with particular focus on the Pacific Northwest. This project will assess and report on the market readiness of this product after examining: 1) freeze protection strategy and operation for both power on (including circulation and heat tape) and power off; 2) tank port layout and threads from both water heating and combined space and water heating system perspectives; 3) electrical connections; 4) labeling; 5) documentation including user and installation manuals; 6) warranty and service provisions; 7) cost; 8) installation training materials and strategy; and 9) marketing and installation strategies.

The project will focus on the performance of different attic assemblies and their associated heating, ventilating and air conditioning (HVAC) systems. Field measurements of attic and HVAC system performance will be conducted in two new high performance homes in California with sealed and insulated attics. One home will be built to be about 30 percent better than Title 24 and the other will be a ZNE home. The attic insulation approach will be a new lower-cost approach using blown insulation that does not use expensive spray-foam. The results of the measurements will be used directly to provide technical support for potential changes to Title 24 and provide information to contractors and builders on sealed and insulated attic performance and alternative approaches.

Three different attic designs will be refined, tested, evaluated, and demonstrated in new home construction. The team will recommend the best of these approaches to home builders addressing cost-effectiveness and energy-efficiency. The baseline for comparison will be current energy efficiency code practices for attic construction involving ventilated, uninsulated attics containing code compliant ducts. The team will evaluate the new design approaches analytically at the start of the project. Researchers will assess approaches that include methods to produce sealed, insulated attics, as well as, standard vented attics, both of which have been demonstrated and are in limited use in the market today but currently add considerable cost to builders. The team will employ new and novel installation methods and materials that have the potential for energy savings on par with ducts in the conditioned space, but at a cost similar to current practice.

This project will assess factors affecting the scale of solar water heating (SWH) installations, such as system cost, performance, and reliability and scale.

The Lighting Research Center (LRC) of Rensselaer Polytechnic Institute will work with the Lighting Design Lab at Seattle City Light (SCL), a leading manufacturer of LED outdoor lighting and a leading controls manufacturer to demonstrate a sensor-controlled, adaptable LED lighting system in the parking lots for municipal, retail, or similar parking lot.

Working with project partners from the Seattle Lighting Design Laboratory, the Lighting Research Center (LRC) will identify a suitable outdoor lighting installation in a parking lot and conduct evaluations of energy and power use, visual responses of people in and approaching the outdoor location, and subjective ratings of safety and personal security while viewing and occupying the location. The design of the lighting installation will utilize published research on the spectral sensitivity of the human visual system for scene brightness perception and on the relationships between scene brightness and perception of safety and security previously published by the LRC project team. The proposed project will consist of a full-scale outdoor lighting demonstration at a parking lot facility within BPA service territory. The demonstration will be based on a proposed specification method for maximizing perceptions of safety and security of occupants, taking advantage of the differential spectral (color) sensitivity of the human visual system for brightness perception at nighttime light levels. Sensations of brightness are in turn strongly related to perceptions of personal safety and security in outdoor locations. It is anticipated that using white light sources such as a lighting emitting diode (LED) illumination in place of conventional high pressure sodium (HPS) illumination energy savings of 40-50% will be possible while maintaining perceptions of brightness, safety, and security.
