Report on a project conducted to better understand the current usage of thermostatic radiator valves by key market players in steam and hot water heating and to conduct limited experiments on the effectiveness of new and old thermostatic radiator valves as a means of controlling space temperatures...
Report providing information about energy-efficient heating, ventilation, and cooling (HVAC) equipment options to help homeowners cut their energy use, reduce their carbon footprint, and increase their homes comfort, health, and safety.
The main principle of smart ventilation used in this study is to shift ventilation from time periods with large indoor-outdoor temperature differences, to periods where these differences are smaller, and their energy impacts are expected to be less.
Fact sheet outlining the research behind how smart ventilation controls boost energy efficiency and indoor air quality, including research findings from seasonal temperature, timer, and real-time weather-based controls showing that all three systems showed potential for energy savings while...
Technical report on a field validation study that utilizes low-cost indoor air quality sensors to assess a smart ventilation system's effectiveness in maintaining acceptable indoor humidity in low-load homes in humid environments, revealing that while the smart ventilation algorithm demonstrated...
Report evaluating the relative effectiveness of various control and distribution strategies to improve hydronic space heating performance in existing low-rise multifamily buildings
Guide describing the use of electronically commutated motors (ECMs) in HVAC central air handler fans to reduce power consumption compared to a single-stage fan motor.
Report providing step-by-step instructions for heating contractors and hydronic designers for selecting the proper control settings to maximize system performance and improve response time when using a thermostat setback.
Technical report describing algorithms that use communicating thermostat heating data and that were developed to optimize customer adoption of energy conservation measures, enhancing the identification of retrofit opportunities, estimating post-retrofit energy savings, and enabling home-specific...
Case study describing an alternative ground source heat pump (GSHP) cold-climate application in an attempt to reduce the installation cost of the ground loop portion by containing the entire loop beneath the basement slab.
Guide describing how to improve boiler efficiency in multifamily central hydronic heating systems by installing thermostatically controlled radiator valves (TRV) to reduce temperatures in overheated spaces.
