How to Choose between an HRV and ERV system

Choosing between an HRV and an ERV

All homes need ventilation, whether natural or mechanical with an ERV or HRV system. Buildings and houses are no longer constructed leaking heat and moist air the way they used to be; we now build them as airtight as we can, especially Passive House or LEED certified homes. This makes mechanical ventilation essential ...

Home lighting design

The first thought of home lighting design should be the orientation of windows for quality of life, but also passive solar heat gain. Not only does the sun offer free heat, but free light as well. Natural and certain types of artificial lighting can reduce the symptoms of Seasonal Affective Disorder (S.A.D.). Studie...
