PNC Financial Services partnered with DOE's Commercial Building Partnerships (CBP) Program to develop and implement solutions to retrofit its existing Singer Island, Florida, branch to reduce energy consumption by at least 30% versus ASHRAE Standard 90.1-2004. Construction was completed in January 2012.
Older, inefficient commercial rooftop unit (RTU) air conditioning systems are common and can waste from $1,000 to $3,700 per unit annually, depending on the building size and type. By replacing or retrofitting them, you can save money, improve your energy efficiency, make your building more comfortable, and help the environment. The Advanced RTU Campaign (ARC) encourages commercial building owners and operators to replace their old RTUs with more efficient units or to retrofit their RTUs with advanced controls in order to take advantage of these benefits. This website shows updates to the campaign including resources and progress towards the campaign's goal.
Case study describing how adidas implemented a best practice of a planned replacement program for its rooftop units (RTUs), which resulted in significant cost and energy savings. The case study outlines the planning process, implementation, results, and the future plans of their RTU replacement program.
This document provides facility managers and building owners with an introduction to measurement and verification (M&V) methods to estimate energy and cost savings of rooftop units replacement or retrofit projects. The M&V methods presented here are helpful in estimating paybacks to justify future projects.
This checklist will assist facility managers and building owners evaluate the capabilities of HVAC companies and the proposals they submit for installation of new HVAC equipment. The questions on the checklist will help owners and managers understand the requirements contained within the ACCA HVAC quality installation Standard 5.
This case study details the very successful Walgreens proactive RTU replacement program that has resulted in 50% efficiency improvements. The streamlined process allows Walgreens to reduce installed cooling capacity, increase RTU efficiency, provide improved service, and reduce overall costs compared to emergency replacements.
The case study details how the U.S. Navy saved over 100 MWh annually with five year payback by installing advanced RTU control retrofit packages at Pearl Harbor, Hawaii.
In FY14, BTO funded PNNL to develop and integrate AFDD methods for both air-side and refrigerant-side fault detection and diagnostics with one of the leading advanced RTU controllers sold in the market today. The work also includes testing and validating the integrated solution in the field. If the results from the field demonstrations show reliable fault diagnostics, it will encourage utilities to provide incentives to pursue the integrated technology because it makes the retrofit controller more cost effective and could make market adoption of the retrofit controller even more attractive to building owners.
Seven AFDD algorithms were developed, deployed and tested on the RTU controller for detecting and diagnosing faults with RTU economizer and ventilation operations using sensors that are commonly installed for advanced control purposes.
This multimedia toolkit is designed to guide energy efficiency program administrators through the process of planning, implementing and measuring a large-scale, deep retrofit energy efficiency program for small-to-medium businesses (SMB). We provide downloadable tools and forms you can adapt for use in your own program.
