Sentences with phrase «building envelope surfaces»

Consensus among microbiologists gives the critical relative humidity for adverse biological activity to occur on building envelope surfaces to be 70 percent.

Therefore, conditions should be maintained within a building such that the critical 70 (or higher) percent relative humidity at a building envelope surface does not occur.

Not exact matches

We quantify sea - level commitment in the baseline case by building on Levermann et al. (10), who used physical simulations to model the SLR within a 2,000 - y envelope as the sum of the contributions of (i) ocean thermal expansion, based on six coupled climate models; (ii) mountain glacier and ice cap melting, based on surface mass balance and simplified ice dynamic models; (iii) Greenland ice sheet decay, based on a coupled regional climate model and ice sheet dynamic model; and (iv) Antarctic ice sheet decay, based on a continental - scale model parameterizing grounding line ice flux in relation to temperature.

In mechanically cooled buildings in hot - humid climates, if interior negative pressure causes moisture - laden outdoor air to enter the building envelope, moisture can condense on cool surfaces, and, if restricted from drying to the inside, problems of material durability and indoor air quality can result.

The modest surface to volume ratio that this affords means less heat loss and therefore a smaller demand on the performance of the building envelope.

A Major Renovation is any renovation of a building where (a) the total cost of the renovation related to the building envelope or the technical building systems is higher than 25 % of the value of the building, excluding the value of the land upon which the building is situated, or (b) more than 25 % of the surface of the building envelope undergoes renovation.

Typically, the risk of surface condensation and mould growth increases with internal humidity loads in buildings and / or reduced quality of the thermal envelope.

/ sq. meter of energy delivered to some part of the building envelope depending in part on the specific surface orientation and angle of the sun's elevation.
