Handling global settings node in MVC partial views on Umbraco site

I'm currently setting up my partial views on my master template, like so:

@inherits UmbracoTemplatePage
@{
    Layout = null;

    IPublishedContent global = Umbraco.TypedContentSingleAtXPath("//*[@nodeTypeAlias='Global']");
}

<!DOCTYPE html>
<html>

    <body>
        @Html.Partial("Header", global)

        @RenderBody()

        @Html.Partial("Footer", global)
    </body>
</html>

The global node being called contains everything needed for the header and footer to work, namely content-managed logos and navigation. As things stand, this works fine.

However, it feels wasteful to have to declare and pass this global node every time I want to grab global settings. My background is with WebForms so while I could just create a class and call this each time to grab the node I'd like to know of a MVC-type way of handling this.

Does anyone know of a clean way I can merge this declaration into a Model or Controller, so that I can call global settings when needed, without having to declare first and call into my partial views?
