Phius Building Certification Manager Al Mitchell provides details on the new Phius Intermittent Exhaust & Make-Up Air Estimator.

Use this estimator to determine a climate-adjusted coefficient of performance (COP) for the Aegis A CO2 Heat Pump Water Heater. This estimator also includes instructions on modeling storage losses associated with water storage tanks per Lync by WATTS' available products. This estimator is applicable for the 250, 350 and 500 models.

Use this estimator to determine a climate-adjusted coefficient of performance (COP) for the Transom Heat Pump Water Heater. This estimator is applicable for the V105, V210 and V420 models.

Use this estimator to determine a climate-adjusted coefficient of performance (COP) for the Ice Air ccHPWH. This estimator is applicable for the 275-D-B, 275-S-B, 550-D-B and 550-S-B models.

Use this estimator to determine the auxiliary energy associated with an active snow-melt system.

Phius Building Certification Associate Zoe Rader shares information on the newly released Phius Project Details Library.

The window comfort and condensation risk criteria apply to all buildings, regardless of size. Use this tool to determine the maximum U-values allowed and demonstrate compliance. New features: Unit conversion (imperial and metric), multiple languages (English, French, Japanese and Spanish) and custom climate data is accepted.

Use this estimator to determine specific or total storage loss inputs for domestic hot water storage tanks when no 3rd party rating is provided or when an AHRI standby loss is known.
