Preservation Standards AND <strong>Guidelines</strong> August 1, 2012<br />
1.4 HISTORIC PRESERVATION AND SUSTAINABILITY<br />
Introduction<br />
Many cities across the country have adopted design guidelines to promote the preservation <strong>of</strong> historic<br />
buildings and the retention <strong>of</strong> their original materials. In the sense that preservation discourages the<br />
replacement <strong>of</strong> original architectural features, design guidelines typically are inherently ―green.‖ While<br />
design guidelines imply sustainability, making direct links between the two is now the approach <strong>of</strong> a<br />
number <strong>of</strong> community preservation efforts. Design guidelines embrace the tenets <strong>of</strong> re-use and maintenance,<br />
thus preserving historic buildings and protecting existing resources from depletion. Preservation‘s<br />
traditional focus on the aesthetic and cultural significance <strong>of</strong> historic buildings is expanding to<br />
highlight the inherent energy-efficient values <strong>of</strong> such properties as well.<br />
Sustainable Development<br />
The word ―sustainability‖ has become a common part <strong>of</strong> our modern language. One familiar definition<br />
that was popularized in 1987 by a publication <strong>of</strong> the United Nations Commission on Environment and<br />
Development is “Sustainable development meets the needs <strong>of</strong> the present without compromising the<br />
ability <strong>of</strong> future generations to meet their own needs.” The concept <strong>of</strong> this definition is that sustainable<br />
development requires consideration <strong>of</strong> the finite supply <strong>of</strong> resources.<br />
Working with Nature: Site Orientation<br />
Historic buildings are <strong>of</strong>ten as energy-efficient as new ones. Buildings constructed before World War<br />
II were designed, constructed, and sited to achieve optimum ventilation, insulation, and use <strong>of</strong> daylight.<br />
Over the past sixty years, as electricity, synthetic insulation, and central heating and air conditioning<br />
systems became standard installations in modern construction, architectural design no longer<br />
required attention to the natural environment. Quality and longevity <strong>of</strong> building materials also became<br />
less important, as these modern conveniences could control the interior climate <strong>of</strong> buildings and materials<br />
were readily available to build anew.<br />
Dwellings in the city's historic districts<br />
were designed with inherent energy<br />
conservation methods in the days before<br />
air conditioning. This included<br />
wide ro<strong>of</strong> eaves, broad porches, windows<br />
for cross ventilation (such as<br />
double hung windows) and awnings<br />
for window shade. (416 NW 22nd<br />
