Ongoing commissioning (OCx) is an innovative approach to managing buildings – it provides continuous improvement in the operation of building systems. OCx is a multi-step implementation process, followed by a step-by-step continuous improvement cycle. Implementing this process within...

Lab and field evaluation of demand defrost controls for walk-in freezers. The purpose of the project is to quantify the energy savings achievable only defrosting on an as-needed basis as opposed to a...

The purpose of this project is to evaluate efficiency/performance of residential variable capacity heat pump (VCHP) systems. These are "traditional American-style" high static ducted systems. There will be one to two systems from three to five...

Xuan Luo,[1] Tianzhen Hong,1 Mary Ann Piette,1 Yixing Chen1Building Technology and Urban Systems DivisionLawrence Berkeley National LaboratoryThis research developed load shape benchmarking using the energy use data of 2,353 small- and medium-sized commercial buildings in California. The load shape...

The typical existing inventory of high mast fixtures is made up of either high pressure sodium fixtures or legacy MH fixtures. This project will evaluate the energy efficiency and demand reduction potential of retrofitting the high masts with the new generation LED fixtures. To accomplish this the...

This project would leverage stationary batteries (existing and new installations) and communication infrastructure for testing DR opportunities at commercial and industrial customer...

In 2013 PG&E engaged Honeywell Smart Grid Solutions (HSGS) to implement and administer a technology assessment project with Demand Response Emerging Markets & Technology funding.  The objective of the project was to test a variety of program features combined (e.g. emerging technology...

The solution selected for study in this report is a connected LED lighting system with embedded sensors and wireless controls integrated into the luminaire. The luminaires can connect wirelessly to wireless access controls (WACs) that are connected to the EMS. This smart luminaire with...

Project SummaryThis report explores the potential role utilities may play in the emerging home energy management (HEM) marketplace and develops a roadmap to leverage, promote, and enable the use of these technologies for energy savings and grid load reduction. It takes a comprehensive view of...

Project SummaryThe primary project goal was to field evaluate radiant panel performance, and to compare performance to that of conventional HVAC systems. A detailed study of field performance would help define best practices and identify opportunities for improving and optimizing these systems....
