The use of multiple design strategies seeking energy efficiency in buildings can offer a wide range of opportunities to improve energy and thermal performance. While thermal resistance is typically considered of high importance, to achieve energy efficiency and prolong the durability of buildings, hygrothermal conditions must also be taken into account. As new technology develops that is capable of measuring a given structure's real-time data, the research community is increasingly relying on software and tools for hygrothermal assessments of buildings. As the tools vary widely in both extent and functionality, defining a method to identify the effectiveness and accuracy of hygrothermal tools for various project scopes presents a technical challenge. This paper presents a systematic review that organizes and summarizes a range of different software for hygrothermal assessment of new and existing buildings. This research review 11 hygrothermal models and tools based on three main characteristics: (1) interface and information transference, (2) hygrothermal assessment and scope, and (3) context and standards. This review seeks to offer a better understanding of technical tools for hygrothermal performance assessment to assist architects, engineers, and designers, promoting last-longing interventions, and improving assessments' accuracy for energy-use estimations.
Weatherization Plus Health (Wx+H), a pilot program introduced by the Washington State Department of Commerce, has proposed a new scope to improve the indoor environment quality (IEQ) for low-income housing residents – one that extends beyond energy benefits. Typical interventions include the distribution of green cleaning kits, walk-off mats, ventilation system upgrades, and resident education, among other elements. Wx+H experts are working to capture the long-term impact of these combined measures to assess the program’s potential. Although guidelines and best practices exist to measure and verify the impacts and influences of energy conservation, these indicators do not holistically incorporate occupant satisfaction and perceptions regarding health benefits in the context of low-income housing. This paper presents a preliminary literature review that summarizes Measurements and verifications (M&V) schemes applicable to the residential sector from two major standards: ASHRAE Guideline 14 and the International Performance Measurement and Verification Protocol. Additionally, reports from the Washington State Commerce Department were analyzed to identify procedures and factors that might influence M&V schemes as applied by Washington State who are leading health and energy programs. Barriers, opportunities, and innovative M&V are discussed.
About Amy Kim
- My work focuses on the interactions between healthy building design, occupants, and building operations. I am interested in assessing the impact of occupant behavior and expectation on building energy use, monitoring the indoor environmental qualities, and building commissioning and management strategies.
