Pilot-Scale Evaluation of Integrated Building Control System for Commercial Buildings

06/02/2023

The California Lighting Technology Center, in collaboration with the California Energy Commission, conducted research to refine and deploy technology strategies that integrate and optimize automated controls for heating, ventilating and air conditioning, electric lighting, and dynamic fenestration (window and door) systems. Project objectives were:

1. Refine and publish an integrated building control system specification for commercial applications including necessary hardware and software components.

LD+A Research Matters: Smart & Clean Exterior Lighting for the Community

02/27/2023

Researchers at the California Lighting Technology Center are addressing the integration and demonstration of exterior lighting systems with on-board solar generation, battery storage and advanced controls with funding provided by the California Energy Commission’s EPIC program. In other words, “smart and clean” exterior lighting systems.

Advanced Lighting Control Systems Bench Testing - Plug Load Controls

04/01/2022

Advanced Lighting Control Systems (ALCS) Bench Testing – Plug Load Controls aims to revisit and refine the technology validation program developed in Phase I. ALCS Bench Testing - Plug Load Controls focuses on the plug load specific additions that are available with select ALCS and evaluates whether these advanced plug loads controllers (APLC) can accurately report the energy use of the connected plug loads consistent with utility requirements/needs.

Energy Code Lighting Language Cleanup Initiative

The California Lighting Technology Center, in collaboration with Southern California Edison, RMS Energy Consulting LLC, and the California Energy Alliance, are establishing a working group of industry stakeholders to help develop recommendations that will simplify and clarify the nonresidential lighting and lighting controls language contained in the 2022 Title 24, Part 6 Building Energy Efficiency Standards.

CLTC & Partners Publish New Article on Outcome-based Code

Outcome-based energy codes are relatively new. They incorporate strategies that quantify a building’s actual energy performance over time to demonstrate code compliance. The term "outcome-based" refers to the fact that compliance is linked with a building’s actual energy “outcome” which may be measured post-occupancy.
