Presentation by Home Performance Contractor Academy giving building science advice for for homes in dry climate zones, specifically combustion safety and combustion appliance zones. Part 3 of 7.
This project analyzed combined condensing water heaters or boilers and hydronic air coils to provide high efficiency domestic hot water (DHW) and forced air space heating. Called "combi" systems, they provided similar space and water heating performance less expensively than installing two...
Second part of an article series focusing on servicing high efficiency modcon boilers. This part focuses on paperwork and follow-up communication with the homeowner for scheduling annual maintenance.
Report about measurements of three recent vintage dishwashers of very different efficiencies showing that while they are substantially more efficient than older dishwashers.
Website describing how solar water heaters -- also called solar domestic hot water systems -- can be a cost-effective way to generate hot water for your home.
Report evaluating lighting and electronic building technologies based on their ability to provide grid services and the type of value provided, including efficiency, load shed, load shift, and modulation.
Research project aimed to verify whether homes in the New Jersey HPwES program achieved 30% source energy savings, and if so, what measures were implemented to achieve them.
Report evaluating HVAC building technologies based on their ability to provide grid services and the type of value provided, including efficiency, load shed, load shift, and modulation.
Fact sheet describing the requirements for EPA WaterSense certified kitchen faucets that highlights flow rate specifications, efficiency code standards, local requirements, faucet types and regulations for building and verifying a labeled faucet to ensure it meets the quality and water management...
