High Temperature Heat Pump 101 Guide

This guide from The Clean Fight and RMI helps building owners and managers understand how high-temperature heat pumps can decarbonize steam and hot-water space heating systems. It outlines key benefits, technology basics, example products, and strategies for effective retrofit integration. High-temperature heat pumps offer a new, less disruptive path to electrification for buildings with steam or hot water distribution.

Energy Recovery Analysis Tools

Summary:

Waste heat isn’t waste—it’s an untapped resource. Recovering energy that would otherwise be rejected from a building can both reduce greenhouse gas emissions and improve the economics of decarbonization projects. This applies across a range of uses, including space heating, heating ventilation air, and domestic water. To maximize the impact of decarbonization retrofits, it’s essential to consider energy recovery during the planning process. By identifying and thoughtfully integrating heat recovery solutions early on, project teams can reduce energy demand, improve system efficiency, and enhance the overall cost-effectiveness of building upgrades.

Spreadsheet tools available for download on this page have been developed to make energy recovery analysis in retrofit planning easier and increase awareness for energy recovery in initial project planning and data collection. The tools provided are not comprehensive design tools but can generate inputs for energy and financial analyses used in investment decision making.

While these spreadsheet tools may be used for any building type, they were developed with existing, large commercial and multi-family properties in mind. Recommended users include staff within the building owner’s organization (e.g., facility manager, chief engineer, energy manager) or consultants supporting a building owner to develop a strategic decarbonization plan.

Source and Sink Inventory Tool

Purpose: Identify locations where waste energy can be captured (sources) and where the recovered energy can be applied (sinks) for evaluation during the retrofit planning process.

Phase: This tool is best used during the Pre-Planning phase when examining a building’s current conditions.

Inputs: Targeted existing condition information from the building’s systems.

Outputs: Transparent characterization and documentation of energy recovery and renewable heat sources relevant to the building to support energy analysis in following phases.

Energy Recovery Mapping Tool

Purpose: Compare building-specific data for source(s) and sink(s) to estimate potential energy recovery. Default assumptions and data are included to streamline the process. The following common use cases are included in the tool:

  1. Capturing heat rejected by the cooling system to improve space heating system performance.
  2. Capturing heat rejected by the cooling system to improve domestic hot water (DHW) heating system performance.
  3. Capturing heat from wastewater to improve domestic hot water (DHW) heating system performance.
  4. Capturing energy from exhaust air to temperature outside ventilation air.

Phase: This spreadsheet tool is intended to supplement other engineering and financial analysis tools during the Planning phase. Additionally, it is recommended the team review the spreadsheet tool during the Pre-Planning phase and identify data collection needs. This is critical, because if data isn’t already being collected the metering will need to be initiated and data collected over a range of operating conditions (e.g. throughout the winter).

Inputs: Input requirements are dependent on the use case:

Uses cases 1 & 2: Short-interval (e.g., hourly) data for source(s) and sink(s) relevant to the energy recovery use case(s) to be evaluated. The data is typically collected using data trending through the building automation system. Additional metering (e.g., thermal energy “BTU” meters) may need to be installed. Data collected should also be reviewed for accuracy and completeness and normalized for factors such as outside air temperature. If data cannot be collected from the building explore leveraging an energy model for estimates.

Use case 3: Attributes about the building’s occupancy, domestic hot water usage, and wastewater.

Use case 4: Attributes about the building’s air distribution system.

Outputs: Annual load and recoverable heat per use case. Data collection initiated to support future heat mapping.

Strategic Decarbonization Planning Training Series

About the Series

NYSERDA and Building Energy Exchange, in collaboration with RMI and Ember Strategies, are excited to offer a comprehensive three-part Strategic Decarbonization Planning training series designed to help industry professionals tackle complex retrofit projects with confidence. Tailored for professionals in engineering, real estate, and technology, this training series will equip participants with the tools and knowledge to drive practical, cost-effective low-carbon retrofits in large buildings. Grounded in lessons learned from NYSERDA’s Empire Building Challenge and their innovative retrofit demonstration projects, participants will learn how to:

  • Identify effective retrofit strategies by evaluating technical solutions and real estate conditions;
  • Make the case for low-carbon retrofits with compelling business narratives that resonate with decision-makers; and
  • Turn plans into action by creating clear, step-by-step decarbonization roadmaps for real-world projects.

Live training sessions for all three courses and on-demand, online courses for Course 1 and 2 are coming this fall. SRead more about our high-impact, solutions driven training series below:

Course 1

SDP: RED Framework and Technical Solutions (1.5 AIA LU)

This first course of the series will explore Resource Efficient Decarbonization (RED) as a replicable solutions framework used to develop carbon neutrality roadmaps for large buildings in cold climates. Using real-world examples from Empire Building Challenge retrofit projects, participants will learn how to apply the RED framework to create comprehensive, long-term decarbonization plans for their buildings. Additionally, the training will review a range of technical solutions for decarbonizing buildings, highlighting how prioritization of these technologies can optimize retrofits.

Course 2

SDP: Building the Business Case for Better Decarbonization (1.5 AIA LU)

The second course will focus on the finance and asset planning components of strategic decarbonization. Participants will learn how to evaluate and align technical solutions with economic realities and long-term asset strategies to inform decision-making. This course will also provide guidance on crafting compelling business case narratives that build stakeholder support and unlock investment for retrofits. By the end of the training, participants will be equipped to develop persuasive business cases that advance building decarbonization projects.

Course 3

Let’s Decarbonize! A Hands-on Building Decarbonization Workshop

The third course of the series will be a highly interactive session offering a hands-on introduction to building decarbonization planning – delivered in a dynamic, game-based format. The session begins with a brief review of key concepts from the first two courses, then, participants will break into small groups to create a mock decarbonization plan for a real-world building scenario. Teams will evaluate strategies to reduce greenhouse gas emissions while weighing factors such as costs, trigger events, and other site- specific considerations. Come prepared to collaborate, apply your skills, and dive into the decision- making process behind effective building decarbonization.
