To promote occupant productivity and ensure a sufficient level of thermal comfort.
Part 1: Ventilated Thermal Environment
All spaces in mechanically-ventilated projects meet the design, operating and performance criteria:
- ASHRAE Standard 552013 Section 5.3, Standard Comfort Zone Compliance.
Part 2: Natural Thermal Adaptation
All spaces in naturally-ventilated projects meet the following criteria:
- ASHRAE Standard 552013 Section 5.4, Adaptive Comfort Model.
See detailed requirement for Thermal comfort
Thermal comfort describes the satisfactory perception of the thermal environment. It is mostly influenced by six factors which are needed to maintain a healthy balance: air temperature, mean radiant temperature, air velocity, humidity, clothing level, and physical activity level.
It can be achieved by applying very high resistance thermal insulation to all room surfaces (including windows), combined with ventilation adapted to the season, doors and shutters, perfect airtightness to avoid unwanted air input and the building’s good thermal inertia.
ISOVER’s range of high performance insulation solutions is constantly being developed with new and innovative products and systems that take the science of insulation to a new level.
Insulating a building envelop reduces heat loss in winter and heat gain in summer. It also reduces the “cold wall effect” that can be experienced as radiating from poorly insulated walls. Insulation keeps walls’ surfaces warmer in winter, reduces condensation on the sides, and improves the temperature feeling in rooms (homogeneous temperature in the living space). It helps to maintain a comfortable temperature in all points of the building.
Besides adequate thermal insulation, the building shell must be airtight in order to prevent the uncontrolled flow of air, as leaky cracks and joints will invariably cause uncomfortable draughts.
