Proper Insulation Can Save your Plants!

This past snow was exciting, beautiful, and for some, provided much needed time indoors.  For others, the snow and subsequent colder temperatures cost much more than they anticipated.

Attic spaces that are not properly insulated can allow heat to escape.  Melting of the snow/ice will ensue (in our case from this storm, up to 3 feet of snow in some areas!!!) thus creating an avalanche of destruction on the foundation and plants below.  In some cases, it will bring the gutters with it!!  Additionally, trying to shovel the snow off your plants will only make it worse.

Properly insulating your home not only saves you on your direct energy cost but will avoid potential subsequent repair cost and is the MOST COST EFFECTIVE amendment you can make to your home at this time!

Petro has on staff LEED AP!

Landscape Architect, Colleen Bathon is LEED AP certified! LEED stands for Leadership in Energy and Environmental Design, and is an internationally recognized certification system highlighting the importance of green building and sustaining our environment.

The program was developed by the U.S. Green Building Council (USGBC), and provides building owners with a framework for implementing and measuring practical green building design, construction, maintenance, and operations. Using the LEED process will help promote sustainable design, buildings and development.  This certification can be applied to both residential and commercial building types. LEED aims to achieve high performance in several areas of human and environmental health including sustainable site development, water savings, energy efficiency, materials selection, and environmental quality.

If you are interested in how your home/building could apply for LEED status, OR interested in learning more about sustainable applications for your site contact us.  info@petrodesignbuild.com

Benefits of replacing Asphalt with Pervious Pavement

Montgomery County Department of Environmental Protection defines pervious pavement as having more air spaces than regular pavement, allowing water to drain through the surface into the underlying soil. Most paved surfaces are currently impervious, but Environmental Site Design (ESD) efforts including installation of pervious pavement are being required for new development as well as redevelopment of properties in Montgomery County.

Applying ESD techniques such as pervious pavement in place of asphalt will help to reduce runoff and issues with flooding, as well as improve water quality. Replacing asphalt surfaces with pervious pavement can provide other ecological, social, and economic benefits.  Pervious pavement functions to slow water and allow infiltration while filtering stormwater on-site. Adding trees and vegetation in previously paved areas can provide comfortable spaces by reducing urban heat island effects and improving air quality as well as overall human health. Pervious pavements and vegetated areas help to reduce energy costs and add aesthetic appeal to any environment (www.montgomerycountymd.gov).

Petro has worked on several projects utilizing ESD techniques, including pervious pavement. Petro used pervious concrete and vegetation to help alleviate issues with pooling and flooding at a residence in Columbia, Maryland. The photo below shows the pervious concrete next to older standard concrete.
