EXTERIOR WALL MEMBER AND CONSTRUCTION
To provide an exterior wall member capable of reducing cooling and heating energy consumption by reducing influent and effluent heat amounts between indoor and outdoor environments in such a situation that the indoor temperature is kept constant by use of cooling and heating equipment independently of the outdoor air temperature changes, and to provide a construction including the exterior wall member.Provided is an exterior wall member, including: an outdoor-side heat insulating layer (A); an indoor-side heat insulating layer (B); and a heat storage layer between the outdoor-side heat insulating layer (A) and the indoor-side heat insulating layer (B), in whichR ≤ 0.20 where R is represented by Equation (3):R=2R1−0.52+R2−12+R3−0.552where R1 is represented by Equation (1):R1=Tb/Kb/Ta/Ka+Tb/Kbwhere Ka is a thermal conductivity of the outdoor-side heat insulating layer (A), Ta is a thickness of the outdoor-side heat insulating layer (A), Kb is a thermal conductivity of the indoor-side heat insulating layer (B), and Tb is a thickness of the indoor-side heat insulating layer (B),R2 is a ratio of a latent heat amount of the heat storage layer in a temperature range of 15°C to 40°C with respect to a latent heat amount of the heat storage layer in a temperature range of -10°C to 60°C, andR3=L5/L20
