Climate Data for Building Simulations

Computer simulations rely on a variety of datasets when assessing the effects of climate on building performance.  These data, and the models they power, provide an important basis for planning, design, and cost analysis.  Below I describe some of the major types of climate datasets used in energy and hygrothermal modeling. Weather Years Datasets described…

Improved Moisture Management With Plan Reviews

In an earlier article, we outlined some general aspects of plan reviews and the benefits gained relative to costs (article link).  Here, we focus on plan reviews related specifically to the building enclosure, including roof, wall, foundation, and floor assemblies.  As with all plan reviews, the purpose is focused squarely on minimizing errors and omissions. However, building enclosure…

Quotes: Construction Documents

“It may be set as the glory of an architect’s specification, that it shall be so clear, that the builders who from it are estimating the probable cost of the intended work, may have to ask no questions; that the specification, shall contain and exact comprehensive and proper description of the work, as it really…

Plan Review

Plan Reviews: Small Investment, Big Gains

Plan reviews are an important quality assurance and quality control initiative.  They offer significant benefits for building owners, designers, and contractors.  They minimize errors and omissions, reduce risks for the designer and contractor, and minimize change orders assisting in controlled project costs.  Other not-so-obvious benefits include: Minimizing requests for information (RFI) thereby improving project workflow Improved…

Making It Green Does Not Make It Right

The principles and practices of green building have had a transforming effect on the way we build, work, and live. By ‘green’ I refer to a collective of high-performing objectives in sustainability, energy-efficiency, healthy building, and resiliency.  Inherent to its mission are claims of improved building performance – that is, perceived betterments in resource use,…

Moisture Performance Of An All-Wood R-30 Wall

Natural alternatives to foam insulation are highly desirable for high-performing wood-framed buildings.  But lignocellulosic materials can be highly bio-nutritive and moisture absorptive, increasing their vulnerability to degradation and reduced thermal performance.  Designers are often faced with the dilemma of selecting materials that are less environmentally safe for much improved performance.  In this article, I describe a…
