Monitor energy—or more

Measurement and verification (M&V) involves recording actual energy use over the course of occupancy, and comparing that data with the estimated energy use seen in the design. The M&V process ensures all systems are performing as specified and identifies any anomalies in equipment, operations procedures or user habits. In addition, an M&V plan can help reduce energy costs, assist with commissioning, and, over time, document and improve the efficiencies of energy conservation measures.

Flame Retardant Used in Polystyrene to be Banned by EU

HBCD is used in all polystyrene building insulation--both extruded polystyrene (XPS) and expanded polystyrene (EPS).

Trombe Walls

Last week I wrote about sunspaces and how they can be used to deliver passive solar heat to our homes.

Way back in the late 1970s, I worked for the New Mexico Solar Energy Association in Santa Fe. I ran the Workshop Program, leading a crew of three or four like-mined idealists teaching mostly low-income New Mexicans about solar energy through hands-on construction workshops.
