A recast of a presentation done for the Fairfax Chapter of Association of Energy Engineers in November of 2013. Presentation focuses on the the Advanced Energy Design Guides published by ASHRAE with association of AIA, USGBC, and IES with funding and technical support from DOE, NREL, and PNNL. In addition, the DOE Advanced Retrofit Guides are also discussed. Both sets of guides are available for download from this resource database.

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 guide covers each major step in procuring a solar photovoltaic (PV) system:
- Conducting technical and financial studies
- Financing a PV system
- Project execution
- Operations and maintenance
- Assessing benefits
The guide provides information on the basic steps, key considerations, and where to go for more information. It is intended to provide an overview and some level of detail, with pointers to highly detailed information and resources.
This roadmap presents a high-level approach to net zero energy building (NZEB) planning, design, construction, and operations, based on NREL’s firsthand experience procuring NZEBs, and based on NREL and other industry research on NZEB feasibility.
This fact sheet discusses NREL's production of conceptual microgrid designs—plans for electrical generation and distribution systems capable of autonomous operation—that deliver reliable, economical, and sustainable energy.
