NEMA ERCS P1 - NEMA’s Electric Resistance Heating Technical Committee Primer on Codes and Standards
January 1, 2018 - NEMA

Introduction Codes and Standards can have a significant impact on a manufacturer's ability to sell products. For instance, some states have adopted building codes that discourage (or even prohibit) the use of electric resistance heating in new buildings. Making matters more challenging, there are...

ASTM E2725 - Standard Guide for Basic Assessment and Management of Greenhouse Gases
February 1, 2019 - ASTM

Overview-This guide presents a generalized systematic approach to voluntary assessment and management of the causes and impacts of GHGs. It includes actions, both institutional (legal) and engineering (physical) controls for GHG reductions, impacts, and adaptations. Options for a tiered analysis...

ASHRAE MODELING & ENERGY - Modeling and Energy Consumption with Parallel and Series VAV Terminal Units with ECM and PSC Motors
January 1, 2014 - ASHRAE

Introduction Since fan-powered variable-air-volume (VAV) terminal units were introduced to the marketplace, proponents of both parallel and series types have argued about which provides a system with the highest energy efficiency.* ASHRAE/AHRI research was undertaken to define the operation...

Andean Hydrology
February 1, 2018 - CRC

This book describes the ecosystem of the Andean watersheds, covering the Californian valley, tropical Andes, and southern Andes. Case studies of the new methods and techniques used for hydrological research in the Andes are provided, and sustainability issues pertaining to Andean water...

NEMA BE P1 - Building System Efficiency Modeling — Improving the Accuracy of Building Energy Modeling: A Study of the Relative Strengths and Weaknesses of Building Energy Modeling Tools and Recommendations for Improvements
January 1, 2018 - NEMA

Executive Summary Building energy modeling (BEM) tools are used to document compliance with energy codes, in green building certification, for incentive programs, to help optimize new designs, and to inform project retrofits. Organizations like ASHRAE and AIA advocate for the wider...

NEMA VT P1 - The Value of Volt-VAR Technologies
January 1, 2018 - NEMA

Executive Summary It's been estimated that every year in the U.S., about five percent of the electricity that is transmitted and distributed is lost.1 This is the equivalent of powering all of California for one year. Reducing electricity losses, even by a small amount, could result in...

NEMA MGRD R2 - State Regulatory and Policy Considerations for Increased Microgrid Deployment
January 1, 2018 - NEMA

Executive Summary Some of the most significant barriers to microgrid deployment are created by policy and regulatory environments that were not designed to enable microgrids. Microgrids are small electric distribution systems that utilize distributed energy resources (DERs) to power a one or...

AWWA M62 - Membrane Applications for Water Reuse
January 1, 2018 - AWWA

Preface Reverse osmosis (RO) membranes have been used in water reuse since the 1960s. Cellulose acetate membranes for treating conventionally clarified municipal effluent was initially applied to small industrial applications and as irrigation water for golf courses. In the 1970s, Orange County...

ASHRAE OR-16-C057 - Getting Heat Pump Water Heaters Into California
January 1, 2016 - ASHRAE

California's single-family residential building stock is dominated by gas-fired storage water heaters. This is a result of the building energy efficiency code. For decades the water heater energy consumption calculated in the budget compliance tools has made it hard to justify using...

Impacting Rapid Hydrogen Fuel Cell Electric Vehicle (FCEV) Commercialization
February 19, 2016 - SAE

Preface Fuel cell electric vehicles (FCEVs) powered by proton-exchange membrane fuel cells (PEMFCs) and fueled by hydrogen offer the promise of zero emissions with excellent driving range of 300-400 miles and fast refueling times of less than ve minutes-two major advantages over battery electric...

ASHRAE OR-16-C063 - Development and Validation of a New VRF Model in EnergyPlus
January 1, 2016 - ASHRAE

VRF (Variable Refrigerant Flow) systems vary the refrigerant flow to meet the dynamic zone cooling and heating loads, leading to more efficient operations during part-load conditions. VRF systems have minimal or no air duct, which also contributes to reduce heat losses. This paper introduces a new...
